Have you ever wanted to plant a strawberry jar but just weren’t sure how to do it? In this article, I’ll provide lots of tips that will ensure a successful outcome.

Strawberry jars (or strawberry pots), those with pockets on the sides, make fascinating container gardens. You can find jars made of terra cotta or plastic, and ceramics with beautiful glazed finishes.

Over the past several years, the stackable plastic sorts have become popular. They are less expensive, true, but it’s hard to walk away from that ceramic strawberry jar that caught your eye (and your heart) at the garden show.

Yes, strawberry plants can be grown in strawberry jars. But, there are many other options, including succulents, herbs, annuals, and even houseplants.

 

 

Planting Succulents In a Strawberry Jar

Terra cotta jars dry out fast because the material is porous, so we must manage them carefully. The succulents, however, love terra cotta!

Dwarf succulents, such as hens and chicks (Sempervivum tectorum, S. arachnoideum), are perfect candidates for strawberry pots. A related genus, Jovibarba, grows in a similar fashion. Both need full sun and don’t mind drying out now and then. Excess growth is easily plucked off and planted elsewhere. The little “chicks”—offsets growing from stolons—cluster close to the “hen”.

To add a little variety to the hens and chicks, include other hardy succulents, such as the small growing Sedum dasyphyllum, S. makinoi ‘Ogon’, S. spurium, and S. ‘Angelina’. Plant Sedum ‘Ogon’ on the north side to avoid sun scald. Most of these sedums are less winter hardy than the hens and chicks, so check their hardiness zones.

Sempervivum varieties grow rosettes of foliage (photo, above) and are available in many colors and bicolors, including green, gray, red, and burgundy. More recent introductions include colors of the sunset in their leaves (‘Gold Nugget’, ‘Orange Glow’). Some varieties have spider webbing, with fine white hairs connecting one leaf tip to another. The leaves of a variety called ‘Oddity from Albidum’ look as though they’ve been rolled into tubes.

 

When It Gets Cold

Hens and chicks are hardy to USDA zone 3 or 4 when they’re planted in the ground. Because roots are exposed to colder air temperatures, however, potted hens and chicks are hardy probably up to the warmer zone 5 or 6.

I’ve seen clay strawberry pots filled with hens and chicks that had been left out all winter in zone 6 Maryland. Because hens and chicks are hardy perennials, they normally survive winter weather. To avoid damaging the pot, though, it’s best to prevent it from repeatedly freezing and thawing. Clay absorbs water, and water expands when it freezes, so, eventually clay pots will weaken.

Keeping the pot quite dry or protected in a sunny shed during freezing weather will help it last longer. Another option is to remove plants from the strawberry jar and heel them into the garden for the winter. Then you can clean the pot, store it dry over the winter, and replant the same plants, or parts of them, in spring.

Gardeners living where winters are moderate to mild can leave hardy succulents outdoors, but others living in cold regions risk losing their terra cotta strawberry pots. You can use plastic strawberry pots instead. Ceramic pots labeled “frost resistant” probably will survive winter weather.

For non-porous pots (plastic and ceramic) that will be planted with succulents, mix a large quantity of extra pine fines, coarse sand, and/or perlite into the soil for faster drainage. Because clay strawberry jars dry out much faster than non-porous pots, they’re the better choice for succulents. However, with enough drainage material, succulents should do well in any pot.

 

 

The Tender Succulents

For the summer growing season, add rooted cuttings from tender (non-hardy) succulents (Echeveria, Haworthia, Gasteria, miniature burro’s tail, dwarf aloe, small cacti, etc.) for their unique coloring and form. Use small, clustering types of plants in the side pockets. Plant a few larger or taller types in the top of the pot. Avoid plants that grow too large because they’ll make the pot appear top-heavy.

All the tender succulents will perish if left outside to freeze. If you want to save them, place the pot in a sunny greenhouse. If you don’t have one, transplant the plants into clay pots at the end of the summer. You could also take cuttings in mid- to late summer so they’ll be rooted by early autumn. Keep tender succulents in sunny windows indoors.

 

 

 

 

Planting Herbs In a Strawberry Jar

Strawberry jars planted with flavorful herbs were sure sellers at the garden shows. When using ceramic containers, check to see if they have non-toxic glazes. Sometimes you’ll see a sticker indicating that the pot is “not suitable for contact with food”, so I would not use those pots for herbs.

Violas planted in the glazed strawberry jar (photo, top of article) sold years ago, in late winter, at the Maryland Home and Garden Show. The manufacturer guaranteed that their pots were resistant to cracking in freezing weather and safe for edible plants. Win-win!

If the root ball doesn’t quite fit the shape of the pocket, a little molding will be necessary. Smaller divisions, younger seedlings, and rooted cuttings fit better into tight pockets. Look for plants in 2-2½” pots or cell packs, or grow your own from seed.

Planting mint with other herbs in a strawberry jar will result in mint growing from every opening! Therefore, it’s best to leave mint and lemon balm to themselves or construct an iced tea pot for the current season.

All plants will get adequate sunlight when growing outdoors in summer, especially if you turn the pot periodically. However, with limited sun indoors, it’s very difficult for all plants in a strawberry pot to get enough sun. This kind of pot will grow well in a sunny lean-to or a greenhouse. But, for growing herbs indoors in winter, choose a pot with a single growing plane. A window box planted with herbs or a simple pot will work better.

 

 

Which Herbs?

Dwarf and creeping varieties of herbs do well in strawberry jars. Use what you like, but trim the larger varieties more often to keep them in scale and for new foliage. Potted plants generally grow to a more restrained size compared to those planted in the garden. Look for herbs at local garden centers or farmers’ markets.

Here’s a sampling, with habit of growth:

  • Basil—small growing ‘Boxwood’, ‘Fino Verde’, ‘Marseillais Dwarf’, miniature purple, ‘Yevani’, ‘Spicy Globe’; the larger ‘Genovese Compact’, ‘Mrs. Burns’ Lemon’, ‘Obsession’ (or other basil downy mildew resistant varieties), ‘Siam Queen’ Thai. Upright, shrubby.
  • Chives—look for the finer-leaved variety ‘Dolores’, but any will work. Upright, tufted.
  • Cilantro—‘Calypso’ and ‘Cruiser’ seem to be the sturdiest, but all are short-lived. Clumping, tufted.
  • Dill—use small varieties, such as ‘Fernleaf’, ‘Teddy’. Upright.
  • Oregano—Greek, ‘Hot ‘n’ Spicy’, Italian. Clumping when young, then trailing.
  • Parsley—curly or flat-leaf varieties, try to find the dwarf flat-leaf ‘Titan’. Upright, tufted.
  • Roman chamomile—fragrant foliage but few flowers. Clumping, creeping.
  • Rosemary—‘Blue Boy’ (dwarf), ‘Chef’s Choice’ (intermediate), ‘Irene’ and ‘Mrs. Howard’s Creeping’ (prostrate varieties), ‘Golden Rain’ (variegated), ‘Hill Hardy’, ‘Salem’. Upright shrubby or trailing.
  • Sage—‘Berggarten’, dwarf silver sage, ‘Icterina’ (gold-variegated), purple, ‘Tricolor’ (mildest flavor). Upright, shrubby.
  • Savory—creeping dwarf savory. Clumping, spreading.
  • Sweet marjoram—‘Compactum’ (my favorite) and others, similar to oregano. Upright shrubby or trailing.
  • Thyme—‘Caraway’, French, ‘Golden Variegated’ (variegated lemon), ‘Hi Ho Silver’ (variegated), ‘Lemonade’, ‘Silver Edge’, ‘Transparent Yellow’, ‘Wedgewood’, and many others. Plant pots with several kinds of thyme for an “All Thyme High”. Clumping, trailing.
  • Viola—a smaller cousin of the pansy, edible flowers and leaves, needs cool weather. Clumping.

Herbs have different life cycles. The annuals (basil, cilantro, dill) need to be replaced once or twice each year. Parsley and viola are biennials. The rest of the listed plants are perennials, but check their USDA hardiness zone ratings to see how much cold they’ll tolerate.

 

 

Other Plants For a Strawberry Jar

 

Colorful annuals spilling out of a large strawberry pot is a lovely sight. For a garden that gets shade or dappled shade, look for the newer ‘Imara’ impatiens, which is impatiens downy mildew resistant. Wax begonias and miniature fuchsias are more possibilities for morning sun or dappled shade.

Dwarf vinca (annual and perennials varieties), bacopa, fanflower (Scaevola), calibrachoa, miniature petunia, diascia, nemesia, alyssum, small varieties of coleus, and plants used in miniature gardens brighten sunny spots. Grow small varieties of scented geraniums for their wonderful fragrances.

Try planting a strawberry pot with houseplants, such as Ceropegia (string of hearts), wandering Jew (Tradescantia spp.), Pilea ‘Aquamarine’, creeping Charlie (Pilea depressa), Peperomia, baby tears (Helxine), moses-in-the-boat (Rhoeo), and dwarf ferns. Small-leaved cultivars of variegated English ivy and rex or rhizomatous begonias add foliage color. Summering outdoors results in vigorous growth, so cut back overgrown plants.

Use plants that need the same conditions, either moist or somewhat dry, sunny or shady. I’ve included photographs of a few candidates, but there are many more worth considering:

Herb Gardens: How To Grow Herbs In Pots

Herb Gardens: The Scents and Flavors of Summer

Fresh ‘Genovese’ basil for the garden salad…savory French thyme on grilled fish…chives and flat parsley to enliven the egg salad and browned potatoes. Yummy! This lengthy article describes how you can plant and enjoy growing herb gardens in containers. Growing potted herbs on the balcony or the sunny patio is the perfect solution if you have no garden space.

Potted herb gardens can be moved around to get just the right amount of sunlight the plants need. They can enjoy the morning sun on one side of the deck, and a few additional hours of afternoon sun on the other. As the sun’s arc changes from one season to the next, you can reposition the plants to capture the most light.

Several years ago, a gentleman asked me to pot herbs into a large strawberry jar. He traveled frequently between his residence and a summer home at the beach. Because he was a keen cook, he planned to take this herb garden with him to the next kitchen, wherever it was. So, if not prohibited where you’ll be traveling, consider taking your herb garden with you on your next road trip!

 

The Gift That Keeps On Giving

Place herb gardens on the picnic table for family and guests to sample as they enjoy the day’s barbecue. And then, in autumn, you can continue the harvest by growing them in sunny windows indoors.

Using herbs to flavor foods might help you kick the salt habit, or at least decrease its consumption. In addition to their wonderful flavors, herbs have high concentrations of beneficial antioxidants, which contribute to our well-being. In decreasing order, oregano, rosemary, parsley, basil, and thyme contain the most antioxidants among the common herbs.

I’ve sold herb gardens as wedding or birthday presents, for Mother’s Day, Father’s Day, Christmas, and as housewarming gifts. Families purchased herb gardens for retiring parents, who planned to devote more time to gardening. Over decades of selling potted plants, I estimate that about half of these delightful combinations were given as gifts.

 

 

Choosing the Right Containers for Herb Gardens

 

clay pots

 

Style and Size

Visit any well-stocked garden center and you’ll see an extensive selection of terra cotta (clay), stoneware, ceramic, wood, and inexpensive plastic pots. Containers are available in all sizes and shapes. Plain or ornate finishes reflect modern, rustic, or classic styles. You’ll also find containers specially fitted for deck railings or for hanging on a wall. Plant a half whiskey barrel with one or more mint varieties, and let them take over…in the pot, that is.

Some ceramics are glazed with materials that should not be used with edible plants. There might be a sticker on the bottom indicating this.

Rabbits are cute, but…

Small clay pots dry out faster than large non-porous pots. Just one day too many in direct sun without water could kill the plants. Lining a clay pot with food-grade plastic and poking a few holes in the bottom will slow the evaporation to a degree. To be sure, your herb gardens—especially small ones—will need daily checking.

Potting herbs in hanging baskets is a great solution if you live where deer and rabbits are waiting for the instant you turn your back. They’re particularly attracted to parsley, cilantro, and dill.

Herbs need excellent drainage, so always choose pots that have holes in the bottom. Other than that requirement, just select the pots that appeal to you. Many gardeners look for a consistent style, favoring pots that harmonize with each other and with the setting.

 

Window Boxes

A popular container for herb gardens is the window box. Window boxes come in many styles, from quite simple to highly ornate. They’re available in terra cotta (lower shelf in photo, above), plastic, and lined or unlined wood. Plastic containers often have plugs in the drainage holes; remove them to ensure proper drainage.

You can hang them outside windows in securely anchored frames; lighter weight containers are a safer bet. Or simply place them on a brick wall, along a sidewalk, or at the edge of a sunny patio. Several herbs in clay pots look charming clustered together on a table. Where wind is a concern, use heavier pots, but don’t place them where they could blow off the balcony to the sidewalk and harm someone.

Cracking

Handle clay pots carefully so they won’t crack. Clay pots might tolerate one or a few seasons of freezing weather; eventually most will begin to spall or crack. When clay absorbs water, and the water expands as it freezes, the clay degrades. Denser terra cotta (Italian for “baked earth”) survives more winters than softer clay.

This clay pot (photo, right) spent almost a decade outside, and it cracked this past winter. Until it crumbles, it will serve some purpose in the garden. I usually used Italian clay pots for my plant business and acknowledge that even better-quality pottery has limits.

Switching herbs into frost-resistant pots where winters are cold is one option. Other options include growing them indoors, in a cold frame, or in a conservatory—in other words, where the pots won’t freeze.

Tuscan Style

Years ago, I planted two herb gardens for a customer in Potomac, Maryland. They sat on a low stone wall surrounding a sunny Mediterranean-style garden. The Italian clay window boxes were over 4′ long and weighed more than 50 pounds empty. They were beautiful when finished—all those shades of green, purple, gray, variegated white and yellow—and the fragrances!

Even without flowers, potted herb gardens have their own unmistakable charm. Green algae and that white coating (efflorescence, from mineral salts) building up on clay pots won’t harm the plants but will amplify the rustic factor. And, yes, you can clean it off if you prefer.

 

Long Toms

Long toms, also called rose pots, are taller than they are wide (top shelf and part of next one, in photo under “Window Boxes”). Variegated lemon thyme or prostrate rosemary cascading over the side are perfect choices.

These pots are available in tiny sizes only 2″ wide, but 4″, 5″, and 6″ pots are more useful. Offer small herb containers as party favors for special occasions or use them to assign seating around the table.

While in Maryland, I potted herbs into 3″ stainless steel long toms for the tables at a popular seafood restaurant. I switched them out every couple of weeks.

I used to purchase clay long toms from a wholesale supplier in Baltimore. They normally came without drainage holes, so I added them, using a reversible drill and a masonry bit. Easy.

 

Plain Pots

azalea pots for herb gardens

“Azalea” pots are 3/4 as tall as they are wide.

Reusing what you have sitting around the garage is most economical.

Clean out those 12″ hanging baskets that held annuals last year, and repurpose them for herb gardens, with or without the wires. Green plastic pots last longer than white ones, which degrade faster in direct sun.

Empty the tired old soil into the shrub gardens and purchase new potting soil for your project. Some plants, particularly basil, are susceptible to several soil borne diseases. Starting with clean materials, therefore, is critical for their success. Wipe down used pots with a 10% bleach solution, rinse, and air-dry…for basil, at least.

Azalea pots are a bit shorter than they are wide and lend a more anchored look to potted plants. I prefer azalea pots over standard pots (height = width). It’s a personal choice, of course. You can pot them up with one plant or use a larger pot for a few plants.

Topiary

Rosemary and lavender topiary standards (the lollipop shape) look great in clay azalea pots, with some moss growing on the soil surface. Grow them indoors, in full sun, where they’re protected from hard winter freezes. But keeping them outdoors—even in chilly weather—ensures they get enough direct sunlight.

Try training the woody herbs “quasi-bonsai” style, with knobby stems, a few little weeds, and a fallen “log” embedded in the moss. Allowing the clay to mellow with algae and efflorescence, and those pots aren’t so plain after all.

 

Strawberry Pots

Planting a strawberry jar is a bit more complicated, so it deserves a post of its own. If your attempts at planting a strawberry pot have been less than successful, refer to this article for solutions.

 

Pot Color

A fine point often overlooked in container gardening is the color of the pot. In summer, with scorching sun bearing down on a dark pot, that heat transfers to the soil. Consequently, the root system will be sparse on the hot side of the pot. Plants are happier without this stress.

You can alleviate their discomfort by shading the root system in summer with smaller pots of heat tolerant plants, such as dwarf zinnias or vinca. Or use white pots in hot weather to lower the temperature.

In autumn, I plant cool season greens and herbs in black nursery pots. Dark colors absorb more energy from the sun. Warming the soil a moderate amount helps limit the deep freeze in winter. The longer the roots can function, the more foliage I’ll be able to pick.

Curiously, clay pots with moist soil can feel cooler to the touch. This is due to evaporative cooling, where the temperature decreases as water evaporates from the surface. So, even in hot weather, a clay pot won’t feel as hot as most other pots. Your skin performs the same function.

Choosing pot colors might not be an option. Alternatively, plant herbs that dislike heat (such as cilantro) on the cooler north (northern hemisphere) or east side of the pot.

 

 

Choosing the Right Plants for Herb Gardens

 

A Proper Fit

First, decide which herbs you want to grow. Look for smaller varieties of the herbs you use in cooking, choosing young but well-rooted transplants. These will adapt better to containers than full size varieties. Sometimes there’s not much choice; maybe only ‘Italian Large Leaf’ basil is available. Okay, I’d rather have it than no basil at all, so there are 4 options when using large-growing herbs:

  1. use fewer herbs in the herb garden to make room for the big basil
  2. keep the basil in the combination pot, but cut it back more frequently
  3. find a larger pot for the herb garden
  4. grow this large basil by itself

We need to find a balance between plant size and available space relative to what other plants need. You can fit a few plants together, but they suffer when cramming all the herbs you like into too small a container. Plants growing in pots, however, don’t grow as large as those in the ground.

 

Seeds and Transplants

Seeds can be sown directly in the pots, but thin them once they sprout. Remember that some species are very slow to germinate, and you most likely will have better success with transplants. For new gardeners, I suggest buying young plants for now, and perhaps experimenting with seeds during the summer. But if the herbs you need are available only as seed, go for it.

Garden centers and farmers’ markets offer a wide variety of herbs grown as transplants. Some growers start them from seed, cuttings, or plugs (very young plants) several times a year. In one growing season, you might find dozens of varieties of basil alone! So, shop around for the local herb lady, and request certain plants she might grow for you.

I included a section on Propagating Herbs, which you’ll find on Page 5.

 

What’s the Difference Between Herbs and Spices?

 

 

Although we use the two terms interchangeably, there is a difference between them. Herbs are leaves of edible plants, and the focus of this article. Spices comprise all other parts of edible plants—bark, seeds, roots, fruits, and flower parts.

Cilantro leaves and coriander seeds come from the same plant, but those interested in this minor technicality differentiate between the herb and the spice.

Turmeric, ginger, vanilla extract, nutmeg, cinnamon, and black pepper are spices that we keep in the pantry. Saffron, the world’s most expensive spice, comes from the 3 threadlike female parts in a fall-blooming Crocus sativus flower.

Tips For Planting A Potted Miniature Garden

Sep15

2019

 

Down To Earth Garden Center, and Planting a Miniature Garden

 

On a recent drive to the mountains of North Carolina, I passed by Down To Earth Garden Center. Maybe it was the charming picket fence, or the need to save time and buy a few packs of vegetables for the deck pots. Either way, the inviting entrance lured me back.

Plus, when living in West Virginia, waaaay back in the 1970’s, I wholesaled potted houseplants to a popular shop called Down To Earth, in the downtown Morgantown retail district. Fond memories…

 

 

Down To Earth Garden Center is located at 1080 South Trade Street, in Tryon NC. Fran and Gary Garside are the owners, and Kiara and Dylan offered friendly greetings and help. After a quick turn around the yard, I asked permission to take a few photographs for the blog. Oliver, the friendly terrier, had no objections, either.

Here’s another small but meticulously maintained garden center.

Check out their facebook page, Down To Earth Garden Center, in Tryon NC.

Phone: 828 859-2283. Call for new hours.

 

 

 

The Newest Project

 

An empty blue ceramic pot sits in our front garden, begging for employment. A while ago, I sowed a pack of older zinnia seeds in it, but they didn’t germinate. So, the pot is looking for work. Construction on our home and others in the neighborhood this summer prohibited any large scale gardening, so I’m eager to exercise some creative horticulture before frost.

 

Thuja occidentalis 'Primo'

Thuja ‘Primo’, an arborvitae.

 

Seeing the dozen or so varieties of hardy dwarf evergreens at Down To Earth Garden Center, I instantly knew what my next project would be. The pot to be planted is roughly 16″ square and 8″ deep. There’s plenty of room for a collection of miniatures, some rocks and gravel, and driftwood with character.

The term “driftwood” is loosely applied here, referring to any piece of weathered wood or woody root. Most of the small pieces I’ve gathered have come from the woods, not from a body of water.

 

Fairy Gardens

In recent years, this style of garden has been called a “fairy garden”, but some gardeners simply refuse to call it that. Let’s just call them miniature gardens. If you or your grandchildren want to dress them up with happy gnomes and resin residences, go right ahead. But for me, a natural landscape is the way to go.

By the way, this is not a new trend in gardening. I remember planting terrariums for a florist in New Jersey, more than 4 decades ago. I used dwarf tropicals, driftwood, rocks and gravel, and life-like little “faux” mushrooms. Merchandisers, however, have captured attention from new audiences by calling them fairy gardens.

Any hobby shop you visit will be stocked with associated paraphernalia, from named fairies and cute cottages to stone staircases. This could be a fun introduction into gardening for our younger folks.

 

Tropicals For a Miniature Garden

Although I will be constructing a garden using cold-hardy species, you might prefer using tropicals for indoor gardens. Garden centers stock miniature plants in 1 1/2″ to 2″ pots for this purpose. You’ll find them as stores gear up for the busy fall (or spring) growing season, but many stock them year-round.

Some species stay small while others eventually will grow too large for a miniature garden. But for a year or so, they’ll do fine. You can find all sorts of ferns, Nephthytis, young palms, peperomia, pilea, baby tears, little succulents for sun, philodendron, and pothos. Young trees, such as Podocarpus, aralia (Polyscias), dracaena, Serissa, and Norfolk Island pine also are available.

 

 

Little Evergreens For the Miniature Garden

 

Picea and Thuja

dwarf evergreens

Some of the hardy dwarf evergreens at the garden center.

From Down To Earth, I selected Picea abies ‘Jana’, a Norway spruce, and Picea glauca ‘Blue Planet’, a white spruce. Each of these globular evergreens grows only 1″ to 2″ in a year when planted in the garden, and less than that in a pot. Their needles are a whopping 1/4″ to 1/3″ long!

Upright growing Thuja occidentalis ‘Primo’, an eastern arborvitae, grows 2″ to 4″ per year, and will serve as a vertical accent in the composition. Dwarf conifers are perfect for trough gardens, rock gardens, and also for outdoor railway layouts.

(***Update***: Each of the spruces grew less than 1″ this past year, and ‘Primo’ added only 1 1/2″ in height. All plants look great, although ‘Jana’ burned a bit at the top during a long stretch of hot weather—100°F heat index. 8/25/2020)

‘Primo’ could easily be mistaken for its cousin, Chamaecyparis, a well-loved genus which I often included in customers’ landscapes and in mine. This dwarf arborvitae has dense fans of tightly-packed foliage whorled around its stems—fabulous textural interest! ‘Primo’ was selected from a crop of seedlings at Iseli Nursery in 2004, and was released to the trade in 2017. Its foliage can take on deeper green to bronze tints in cold weather. When planted in the garden, this variety will grow to about 3′ tall and 1 1/2′ wide in 10 years.

A Holly Called ‘Jersey Jewel’

Down To Earth also had dwarf junipers, Cotoneaster, a ferny Chamaecyparis, and a holly with the cutest and tiniest round leaves. It was difficult narrowing down the choices to 3 plants. Hmmm…I might have to go back for that holly. (***Update***: A couple of months later, I did go back for that holly, Ilex crenata ‘Jersey Jewel’, when my visiting brother, Jeff, and I went for a drive in the mountains.)

 

 

The Cold Facts

 

 

All 3 dwarf evergreens are hardy to minus 30°F, or USDA zone 4. Because they will be kept above ground level, in the pot, their roots will not be insulated by surrounding garden soil. On an average winter night here in zone 7b (borderline 8a), however, the soil probably will freeze only an inch or two into the pot. I’m more concerned about summer heat in this area.

So, how, then, do spruces and firs survive way up in the frigid north? First, they evolved there, and their cellular chemistry has adapted to harsh conditions. Second, a blanket of snow and a layer of forest floor debris help protect plants’ roots, to a degree, even if air temperatures plummet to well below 0°. And those are the full-sized specimens, with roots that venture more deeply than the tiny evergreens I’ll be using in the pot.

 

Other Variables

Large pots in winter sunlight absorb more heat than small ones during the daytime, and release it to the atmosphere at night. And the more hours of sun, the better. You can see how a larger soil mass offers better protection from the cold than a smaller one. It takes more time for a greater volume of soil to release the warmth gathered during the daytime.

Consider, also, the color of the pot. Dark pots absorb more energy from the sun, sometimes making the difference between life and death for their inhabitants. In this case, I already have the blue pot, and it’s a light shade of blue at that. But later I’ll describe other tricks we can employ when dealing with harsh winter weather.

This container has survived many winters outdoors without cracking because it’s frost resistant. Still, there are no guarantees. For those pots that have great value to you, empty and clean them, and store them upside down in the shed or the garage.

Within reasonable limits, most of us in the U.S. can find something to grow in winter pots. Just look for the hardiest specimens you can find, and get some advice from an expert at your local garden center. If live plants are out of the question, consider berried stems, colorful twigs, cut greens, moss, pine cones, and other seasonal ornamentation for the decorative pots by the front door. Or you might choose to take the risk with live plants.

In Unusually Cold Conditions

 

Hardiness Zones

Each variety of tree, shrub, and perennial is assigned a winter hardiness zone. That zone represents the lowest temperatures it can tolerate when planted in the ground. It’s useful when labels include the range of tolerance, such as “USDA zones 4-7”.

Regions on the USDA plant hardiness zone map are divided in ten-degree increments. The additional “a” or “b” designation further narrows down each zone to slightly cooler or slightly warmer parts, respectively. So, zone 7b is 5° warmer in winter, on average, than zone 7a. The zone numbers increase as average winter temperatures increase from Canada to the southern U.S.

It’s not unusual in this area of North Carolina to see temperatures drop into single digits a few nights each winter. And, conversely, we sometimes have those glorious winters that rarely get below 25°! Normally, I recommend using plants for planters that are rated two zones hardier than the zone you’re living in. For example, a zone 5 Pieris japonica that should tolerate winter temperatures as low as -20° planted in the ground likely will survive a zone 7 winter (0° to 10°F) in a pot.

 

The Weather Report

The last weather report of the day will determine if anything needs to be done for the plants outside. I’ll probably move the miniature garden to the warmer back deck, which is protected by a fence. That’s where plants, including edibles in pots, will get the most hours of direct sun.

The corner between the shed and the back wall provides a cozy microclimate. And, if needed, I can move the miniature garden into the shed or indoors for the night. But I’d rather not; it’s rather heavy.

 

Cold Frames

Let’s say you live in the cold northern states, but you want to pot up a miniature conifer garden. You’ll need to provide some protection when temperatures drop so low that the plants are at risk. Here are a few suggestions for those areas where these conditions last for months.

Move the pot into a sunken cold frame, or one that is lightly heated by a heat mat or heat cables. Heeling (burying) the pot into the soil, inside the cold frame, will give more protection by insulating the root system. Or you could pile mulch around the pot up to the rim.

Where winter conditions are cold but not severe, heeling in the pot next to a south-facing wall might be all the protection required. Or move it to a covered sunny porch against the wall of the house. Avoid placing it where ice or snow from the roof might fall on the plants. Watch out for animals that like to dig. Surround the planting with deer netting or a wire barrier (chicken wire, hardware cloth) to prevent damage.

The cold side of a heated greenhouse, an unheated lean-to, a minimally heated sunroom, or a sunny garage window might work during the frigid winter months. The plants will need direct sun even though they’re dormant in winter, but keep them very cool. And don’t forget to water! When cold, the miniature garden will dry very slowly, but it still needs to be checked.

If it’s too warm, the plants will beak dormancy prematurely. But, without adequate sun, that new growth will be weak.

Here’s A Bright Idea

Another option is to surround the pot and soil with a string of indoor/outdoor miniature incandescent lights. Enclosing the whole thing, or just the pot, in plastic at night creates a “lightly” heated bubble of protection.

I’ll use this simplified version of a cold frame during periods of severe cold, meaning temperatures in single digits at night. But I probably won’t wait for the temperature to drop that low. These varieties are new to me, and I don’t want to lose them.

cold frame

Setting up the cold frame in autumn.

In the Maryland back yard, I assembled the cold frame (photo, right) every autumn. Succulents, geraniums, cyclamen, and other plants that tolerated cool temperatures, but not frost, spent the winters there. Edible cool season greens grew continuously under cover. And all received abundant sunlight in the back yard, on the south side of the house.

Cinderblocks and boards supported sheets of durable twinwall polycarbonate above the patio. Extra bricks on the north side (above cinder blocks) helped slope the cold frame toward the south for drainage and a better orientation toward winter sun. I used clear 4-mil plastic to cover the entire frame, sealing up the sides. And I weighed it down so it wouldn’t blow away.

The purpose of the strings of Christmas lights is to give gentle warmth, not light. So, use incandescent lights, not LED’s. The number of strings used in the cold frame varied with outdoor temperatures and with the amount of warmth needed for a particular group of plants. A string of 100 mini lights provides about the same warmth as a 40-watt light bulb.

 

Keeping Their Cool

These evergreens grow best when exposed to natural seasonal variations. But because the roots are above ground, they are more limited in what they can tolerate.

In any case, don’t keep hardy plants on display indoors or enclosed under plastic any longer than necessary. They might break dormancy, and could suffer cold damage when exposed to normal temperatures again. Open or remove the plastic covering every morning, before the sun heats the space.

How To Transplant Houseplants

2019

Updated 9/26/2024

 

 

Time To Transplant Houseplants?

 

 

potting soil, how to transplant houseplants

 

 

As the end of the growing season approaches, we need to prioritize all the chores that need attention. Do the houseplants require transplanting? The plants that summered outdoors must come back inside soon, before frost damages the foliage or kills the plants.

They’ve been luxuriating on the porch, in higher humidity and brighter light than they usually receive inside. It’s no wonder they look fabulous! So, reintroduce them to indoor conditions while the days are still somewhat long and before the furnace kicks on and dries the air.

Perennials that looked picture perfect in May now look a little stressed after those record high temperatures. And the tired vegetable garden needs fresh compost or aged manure before setting the fall crops.

In a few weeks, flowering bulbs will arrive at garden centers…with pansies, violas, snapdragons, dusty miller, and Heuchera, trailing ivy, and hardy grasses. You’ve been dreaming of those beautiful combination planters, like the ones you saw last autumn at the garden center. But first things first.

 

 

Should We Transplant Houseplants Now?

 

Let’s start with the houseplants. Exposing tropicals to cooling temperatures outdoors, as autumn takes hold, could stress your houseplants. And some of those plants are pleading for attention right now.

While certain plants can tolerate cooler temperatures (cyclamen, ferns, English ivy, succulents, ponytail palm), others can’t. The aroids (peace lily, Dieffenbachia, Anthurium, Philodendron, Alocasia, Chinese evergreen, pothos), prayer plants (Calathea, Maranta), and some of the begonias, for example, should come indoors before temperatures dip below 60°F.

Although they won’t be killed by a few nights in the 50’s, or even the 40’s, you don’t want to prolong their discomfort. Chilling stresses many of our tropical houseplants, and can rot roots and disfigure foliage.

 

 

Inspect Them First

 

You probably won’t need to transplant houseplants, summering on the porch, that were repotted in the spring. All you need to do now is to inspect them for insects and spider mites before bringing them indoors. Check the bottom of the pot for slugs and sowbugs hiding around the drainage hole.

Clean up the leaves, too, and remove any that are discolored, insect-eaten, or damaged. Peel away the entire leaf, so none of the leaf stems (petioles) remain that later will turn yellow or brown.

After the inspection, wipe down the pots, wash the saucers, and place the plants in front of the windows where they seemed to thrive last winter.

 

Horticultural Oil

The dwarf Ficus neriifolia contracted a scale infestation, so I sprayed it with a horticultural oil solution. For insects and mites, horticultural oil works very well. It smothers the pests and is safe to use on most plants, including edibles.

Wiping the horticultural oil solution on smooth leaves (fiddle-leaf fig, pothos, peace lily) with a soft sponge removes dust, grime, and residue from water and fertilizers. It gives them a nice luster without appearing artificial. Read the label; I prefer to use less oil than is recommended on the label—to start with, anyway. Horticultural oil makes surfaces slippery, so be careful.

Do Your Houseplants Actually Need Bigger Pots?

Knowing if the plant needs repotting, when to repot, and how large a pot to use is half the battle.

Does it wilt often? Perhaps instead of repotting, the plant needs to be deeply watered. Or maybe the roots have rotted in waterlogged soil, or the water rushes right through without moistening the soil.

I’ve seen a lot of dead plants over the years, and many simply were in pots that were too large. “Aren’t we supposed to transplant houseplants every year, just like our children outgrow their shoes every year?” No; once they have matured, plants can stay potbound for quite some time.

“If I transplant houseplants into bigger pots, won’t that make them grow faster and bigger?” No, another myth! If you transplant houseplants into pots twice the size they need, they more likely will die faster.

Large pots hold large quantities of soil and water. When the moisture is not used by the plant, the sodden mass just sits there, cutting off the oxygen supply and rotting the roots. So, if the entire volume is not tightly filled with roots, the plant doesn’t need to be repotted.

Many houseplants like being potbound. English ivy (Hedera helix), pothos (Epipremnum aureum), Philodendron, palm trees, Ficus trees, African violets, succulents, snake plants (formerly Sansevieria, now Dracaena), and bonsai prefer somewhat cramped quarters. Many potted herbs (rosemary, lavender, chives, sage, thyme) also fare better when potbound. But, in order to ensure good health, gardeners must provide nutrients according to the needs of the particular plant, and according to the time of year.

It’s helpful to know the habits and preferences for each kind of plant. For example, although the 4′ tall variegated snake plant (Dracaena trifasciata ‘Laurentii’) eventually will need a 10″ or 12″ pot, its cousin, the dwarf bird’s nest species (D. hahnii), can stay in a 4″ or 5″ pot for many years!

 

Fertilizing Houseplants

Most tropical plants spending the winter indoors won’t need fertilizer until late winter or early spring. If they continue to grow and look healthy, and they’re receiving good light, though, diluted solutions (1/4 to 1/2 strength) can be added every 4 to 6 weeks. Err on the side of using less fertilizer in winter.

As long as they’re properly watered and fertilized, your plants can remain perfectly happy while potbound. In fact, they’re easier to manage this way, since there’s less likelihood of overwatering. But you’ll have to water more frequently.

Look for products formulated for foliage houseplants or for flowering plants. They’re available in several forms: timed-release prills (use a low dose from fall through winter), liquids, granules, and soluble crystals. Read the label.

 

Fungus Gnats

Plants in smaller pots are less susceptible to diseases, root rot from overwatering, and fungus gnats. Ever have those annoying little “fruit flies” around your houseplants? The simplest remedy is to allow the soil surface to dry out.

Female fungus gnats lay eggs on moist soil. When the tiny larval worms emerge, they eat small roots, sap on cuttings, fungus, and organic matter in the top inch or two of the soil. Let the surface of the soil dry before watering again, and you’ll have fewer fungus gnats. See if adding a 1/2-1″ layer of pine fines as a mulch might prevent gnats from laying eggs.

Yellow sticky cards are good for catching flying insects. A card placed horizontally near the plants, on the pot’s rim, or in a sunny window attracts the most gnats.

 

Save the Spider!

The spider plant in the 4″ pot that your girlfriend gave you two months ago is literally crawling out of the pot. She propagated it from one of her own plants, so it has sentimental value.

Spider plants, related to other strong-rooted Asparagaceae (formerly Liliaceae) family members, develop roots that circle around the inside of the pot. The vigorously growing roots raise the entire plant higher in the pot, opening up air spaces around the root ball. This dries out the finer roots, and water gushes immediately through the drainage holes without moistening the soil. Clearly, it’s time to work on this one.

 

 

When Should I Transplant Houseplants?

 

A good time to transplant houseplants is in spring to mid- or late summer. Plants that recover slowly (for example, succulents) should be repotted, if needed, by mid-summer. In autumn and winter, plants receive fewer hours of daylight, photosynthesizing at a reduced level. Our slower growing tropicals don’t grow much foliage in autumn and in winter. And roots also are reluctant to grow.

Cooler temperatures, compared to the balmy summer days spent on the porch, cause systems to slow down. So, trying to force plants to grow at a time when they’re entering semi-dormancy often does more harm than good. Plopping a plant’s almost dormant root system into wet soil and expecting it to grow is asking the plant to do something against its nature. It would rather stay semi-dormant.

greenhouseProviding a greenhouse atmosphere—warm, humid, and sunny—keeps your houseplants in much better condition, even through the shortest days of winter. Optimal light levels increase rates of photosynthesis, respiration, and transpiration. As a result, they might grow almost as fast as they did in June.

But most of us deal with dryer air, energy-saving chilly nights, and dim lighting (in the plants’ eyes) until the hyacinths bloom outside.

Plants, both indoors and out, take on renewed vigor once the days lengthen closer to springtime. Some of us humans do, too.

 

 

How Big Should the Pots Be?

 

succulent dish garden

I’ve grown dwarf peperomias and miniature succulents, such as Echeveria minima and Haworthia truncata, in 2″ pots for many years. Since the succulents are prone to rot in wet soil, keeping them very potbound decreases the chances. There simply isn’t that much soil in the little clay pot, and it dries fast in direct sunlight.

Most of the succulents I enjoy growing are on the small side, anyway. Almost all are in 1½” to 4″ pots, and others have been planted in larger, but shallow, bonsai trays.

I brought with me from Maryland a 4½” pot of Drimiopsis kirkii, one of the African leopard lilies, and it has yet to be repotted into a larger pot, 6 years later. Its cousin, Drimiopsis maculata, however, grows from bulbs which multiply faster than those of D. kirkii. So, most of the D. maculata plants get divided more often, but they’re still in 4½” pots. Older plants are moved into 6″ pots, and remain crowded until divided.

Dracaena hahnii, the dwarf snake plant, lived happily for years in a 4½” pot. The small, glossy-leaved Spathiphyllum wallissii would have complained if it had been bumped up into anything larger than its 6½” plastic pot.

 

pink cyc.

We’ve had this miniature cyclamen for years.

 

A pink flowering miniature cyclamen stays in its 4½” pot (photo, above), year after year. Now, in late summer, it is coming out of dormancy and beginning to grow new foliage, contrary to what most other plants are doing. That’s because its growth cycle calls for cool to cold, but not freezing, temperatures in order to set flower buds. It will be fertilized accordingly, for a full canopy of marbled leaves.

The plant’s habit and its root structure help determine the required pot size. In general, transplant houseplants into pots that are only 1″ to 2″ wider, and only if they need it.

 

The Old Weeping Fig

Variegated weeping fig.

A weeping fig (Ficus benjamina), given time, will grow to the ceiling. Instead of raising the roof, its height can be managed by “aesthetically” cutting stems back in the spring, when it will respond faster.

I grew a variegated weeping fig in a 14″ pot for about 15 years, in front of a big window that received a few hours of morning sun. When the tree grew to almost 8′ tall, above the top of the window, I pruned it back a few feet. Then, when it regrew, all the foliage was once again in the sun and at eye level.

 

African Violets

 

African violet

A healthy African violet.

 

African violets (Saintpaulia ionantha) are happy to stay in 4″ pots for years. Miniature African violets need smaller pots than that.

A rule of thumb for pot size and an African violet is to plant it in a pot that is 1/3 the spread of the foliage. So, a 4″ pot will accommodate a plant that is 12″ wide. Plants in top condition might take a slightly larger pot, but you have to pay very close attention to moisture and soil drainage.

“What should I do with an African violet that has a long trunk?”

As these plants grow new leaves from the top of the rosette, older leaves lower on the stem die off. That’s part of their natural growth pattern. When the plant develops a trunk, it’s time to make an adjustment. But don’t do this if the plant is slowing its growth. Spring to mid-summer is a better time for this procedure.

Remove the plant from its pot and slice off the bottom third of the root ball. Shave off a small amount from the sides as well. Wash the pot, check the plant for insects (mealybugs, especially), and treat with horticultural oil if necessary.

Place a small wad of polyester fiberfill (from a craft shop) over the hole. Add a small amount of African violet potting soil in the bottom of the pot. These plants like peat moss in their mix. Set the plant in the pot, and fill in the sides with more soil, using a chop stick to firm soil in the gap.

Part of the trunk will now be loosely covered with soil, and it will grow new roots. The top of the root ball should be lower in the pot than it grew previously. (Yes, this is exactly what we don’t ordinarily recommend.) Water it in, using lukewarm (about 85°F) water. Keeping the soil too wet will rot the trunk and the roots.

If needed, use the kitchen sink sprayer to wash soil off the leaves, using lukewarm water. Towel off the water drops, and let the plant dry in a warm location.

It’s less stressful for these plants if this is done every year or two, before the trunk grows a few inches tall. But I have seen perfectly happy violets with long stems curling over the edge of their pots.

“What are those marks on the leaves?”

Water the soil—always lukewarm for African violets—and avoid wetting the leaves. If water splashes on the leaves, absorb it with a towel, and let the plant dry in a warm place. As drops of water chill on this plant’s leaves, unsightly tan or brown rings and lines will be left behind.

Grow African violets at 70 to 74°, and fertilize regularly with a product formulated for this genus.

 

Less Is More

stack of clay pots, transplant houseplantsMove miniature species of plants into something only 1/2″ to 1″ larger, if they need it. I know; that doesn’t seem like it could make much of a difference. But for the plant whose roots, in the wild, might be crammed between layers of sedimentary rock on a blustery cliff, 1/2″ is plenty.

Large-growing plants require new pots up to 2″ wider in diameter. Peace lily (robust varieties of Spathiphyllum), weeping fig (Ficus benjamina), Chinese evergreen (Aglaonema spp.), and larger palm species can be moved from 6″ starter pots into 8″ pots. And, importantly, this assumes that the roots tightly fill the smaller pot.

Many of the tropicals will survive and prosper over the next several months, even while very potbound. If they’re already in 8″ pots, they’ll likely be fine until spring, when they can be potted on if needed. The 6′ tall fiddle-leaf fig in an 8″ nursery pot, though, can go into a 10″ pot, since the heated sunroom has floor-to-ceiling windows. Sunny conditions encourage plants to grow new roots, but carefully monitor soil moisture. Avoid watering houseplants (especially succulents) on cloudy days.

If growing conditions in your home are not ideal, but plants absolutely need to be repotted, transplant them now, before fall, into slightly larger pots. Wait until spring to transplant large houseplants, if it’s needed at all.

Houseplants don’t require repotting every year. Once they have attained a mature size, they no longer need to be moved into progressively larger pots. Instead, regularly fertilizing with products formulated for houseplants will supply all the nutrients they need.

Grow a Potted Tomato: A Step-By-Step Guide

Apr8

 

How To Grow a Potted Tomato

 

 

young tomato plants

Young tomato plants.

 

 

This year’s plan is to grow two potted tomato plants on the deck, inside the fence and away from deer. But less than a week ago, it snowed! For the near future, we’ll be having temperatures in the 70’s F, and in the 50’s at night. It’s time!

Judging by the numbers of people shopping at the garden centers, I’m not the only optimist out there. Always check your local forecast to see if it’s safe to plant tender edibles. Our friends in the North are still shoveling snow. Sorry, guys. Here are today’s purchases, and the step-by-step guide on page 2.

Tomatoes

 

Warm temperatures turn thoughts to tomato plants, so off to the garden center I went. Since we rarely buy tomatoes from the grocery store in the winter, we’ve been looking forward to this moment.

In one of the pots, I’ll include a young flat-leaf parsley and a sweet basil I bought at the grocery store a few weeks ago. The two herbs will be planted on the south side of the heirloom ‘Rutgers’ tomato, so they won’t be shaded. I’ll remove tomato leaves that interfere with the herbs. In case raccoons and squirrels set their sights on a lovely ripe fruit, bird netting wrapped around the fruiting plants will deter them.

Unfortunately, direct sunlight is decreasing in the vegetable garden, next to the house, as the trees to the south grow larger. Even so, the new ‘Sun Gold’ cherry tomato will go into the garden; if any tomato will produce a crop, ‘Sun Gold’ will. Besides, it did well enough last year. It produces loads of bright orange super sweet tomatoes, great for salads and snacking. Bet you can’t eat just one!

 

 

Basil

 

Tuscany basil

‘Tuscany’ basil.

The garden center also had ‘Tuscany’ basil, a light green lettuce-leaf type, with huge puckered leaves. It is wonderfully sweet and lightly spicy, with a hint of fresh anise flavor. ‘Genovese’ and lettuce-leaf basil are among my favorites for Tomato-Basil Salad.

And I added to the cart a pot of ‘Siam Queen’ Thai basil, for the baked salmon. Basil needs warmer temperatures, so they’ll stay in pots for a while, and come inside at night. Potted basil will come indoors even in summer, during rainy or humid weather. That’s when Basil downy mildew becomes a problem.

Curly parsley, a rogue seedling with last year’s flat-leaf parsley, and arugula survived the winter and still look good enough to hold onto for a while. The enclosed deck is a warmer microclimate, where winter temperatures are always higher than on the other side of the fence.

Although there’s some potting soil around, I’ll need more to fill those large pots and a few others. So, I bought the largest bag of soil the garden center carries. There’s enough packaged fertilizer left over from last year.

 

 

Caterpillars, Anyone?

 

I always keep a supply of Bt for battling the caterpillar invasions. Bacillus thuringiensis (Bt) is an organic alternative to substances I’d rather not consume, yet many people still consider it a “chemical”. It is not. Bt is a naturally occurring bacterium. An occasional spraying with Bt on the cole crops (kale, broccoli, cabbage, etc.) and on parsley and dill will save them from utter destruction!

 

tobacco hornworm

The tobacco hornworm on a tomato leaf.

 

Sometimes, 1 or 2 tobacco hornworms attack our tomato plants. They look very similar to the tomato hornworm, which has V-shaped markings instead of the tobacco hornworm’s slashes (photo, above). They’re difficult to see because they blend so well with the foliage.

Left undisturbed, these larvae will develop into a type of hawk moth. But this very hungry caterpillar, as it grows, consumes large quantities of leaves, and leaves behind…well, you know what it leaves behind.

This nature nerd, as a young student, kept a tiny caterpillar indoors, and supplied daily rations of tomato leaves. Well, it grew enormous and wandered off to a secluded spot to pupate. My greatest fear was that my mother would find it. I finally found it, and donated it to a teacher’s Wardian case.

Spraying with Bt kills these hidden caterpillars if you can’t find them. It is more effective, however, when used on young caterpillars. But, if they have little things on their skin that look like grains of rice (photo, above), just pluck off the caterpillars and place them in the shrubs. A small female parasitic wasp laid eggs on or in the caterpillar, and the wasp larvae fed on and will soon kill the caterpillars. The “rice” grains are pupating wasps. And some little animal might appreciate a morsel such as this.

Big Pots

 

I bought two 7′ tall stakes and two 20″ diameter lime green pots, at first considered somewhat disagreeable, but now perfectly acceptable. This shade of green blends in with the greens and browns on the deck. When summer heat is a problem, light colors reflect some of the hot sun bearing down on the pots. This helps moderate soil temperature, which rises in a dark pot. Conversely, in the winter, black pots absorb warmth, keeping hardy herbs and cool season greens happy.

Discounted prices on vegetable transplants accomplished their intended effect: I bought more than I had planned. So, now there are 2 sweet peppers to plant, one a “green-to-red-when-ripe” bell, and the other a ‘Lunchbox’ orange.

 

Peppers

 

Lunchbox peppers

‘Lunchbox’ sweet peppers.

 

‘Lunchbox’ peppers are small and colorful (red, orange, or yellow—a separate color on each plant). I add them to omelets, salads, stir-fries, shrimp and vegetables with rice, and pizza.

They add great color accents as well as a higher vitamin C content than green peppers. In fact, one medium-large ripe lunchbox pepper has 100% of the RDA for Vitamin C.

It takes almost 3 weeks longer for a pepper to mature from the green stage to the colorful one. Normally, I would have waited a week or two for the pepper plants, but they were on sale…and it has been quite mild…

(“Weather Alert: severe thunderstorm watch, possible large hail, winds gusting to 60 miles per hour”. Time to move some things around outside.)

 

One More Tomato

The heirloom ‘Black Prince’ tomato is not as susceptible to cracking as some of the other black tomatoes. And the fruits are smaller. This one substitutes for the ‘Black Krim’ I was looking for.

If ‘Black Prince’ doesn’t do well enough, I’ll pull it out and plant something else. That’s one of the many advantages of living where the growing season is long. (***Update***: The ‘Black Prince’ has grown taller than the 7′ stake, and it is loaded with medium-sized fruits! I’ve already picked more than 20 richly flavored “black” tomatoes. Photo at end of Page 2. June 25, 2019)

 

And Zucchini

Zucchini with fruits.

The fourth of the four-for-$10 deal is a zucchini called ‘Black Beauty’. The seedlings have barely grown beyond the seed leaf stage, and they, with the basil, come indoors at night.

A 50-pound bag of aged cow manure rounded out the purchase.

I’ll plant the zucchini into a nursery pot, and later into the garden. But for now, the garden is still packed with cool season vegetables and greens.

What Is Wrong With My Houseplants?

Jan4

 

2019: HAPPY NEW YEAR!

 

Does your list of New Year’s Resolutions include paying more attention to your houseplants? Now that the busy holidays are over, we’re almost back to our routines. The plants look forward to returning to their normal locations. They missed those bright windows!

If you’re dissatisfied with your plants’ appearance, today might be a good day to give all the houseplants a thorough examination and a good cleanup.

 

Philodendron selloum, easy houseplants

Philodendron selloum adds a tropical element to the indoor environment.

 

 

What Is Wrong With My Houseplants?

 

Let’s begin with some easily recognized problems:

  • the plant has collapsed into a sad-looking heap of wilted foliage
  • leaf tips are brown
  • leaves are turning yellow
  • many of the leaves are dropping off
  • the flowers are gone

But your houseplants have sentimental value, so they’re not going into the trash…or into the compost pile. And you know they probably will recover with a little attention. After all, the same thing happened last year.

A home without houseplants looks sterile—to me, anyway—so there will always be indoor plants wherever we live. They rid the air of benzene, formaldehyde, and other pollutants. In return, we get a small boost in the humidity and oxygen content of the air we breathe.

And we enjoy living with nature. Many studies point to the psychological benefits of living with plants at home, at the office, in school, and in the community.

With the renewed interest in growing houseplants, a huge number of species and varieties are available. Popular plants, such as Fiddle-leaf fig (Ficus lyrata), are in such high demand at garden centers that supply is often difficult to maintain.

Several dozen plants are protected here, and will be covered with plastic for the night.

There are hundreds of plants in my collection, from 1″ tall miniature Haworthias to a 6′ tall 40-year-old ponytail palm (Beaucarnea recurvata).

Many succulents and half-hardy perennials spend the winter in the cold frame outdoors, heated with a few strings of miniature incandescent Christmas lights and covered with 2 or 3 sheets of clear plastic (photo, right). There’s just not enough room inside for everyone!

We often have warm winter days in the Carolinas. This gives some houseplants the opportunity to spend a few afternoon hours on the enclosed deck, basking in the mild sunshine.

 

 

My Peace Lily Is Wilting

 

Spathiphyllum, or peace lily, popular houseplants

Peace lily, Spathiphyllum.

Wilt in peace lilies due to underwatering is a common problem. There are few plants that exemplify wilt more clearly than this one. A dry but still living peace lily, once watered thoroughly, will recover. But a few leaves might turn yellow, and they won’t green up again.

Peace lily (Spathiphyllum spp.) is commonly available and a good choice for beginning gardeners. You see them in malls and offices all over the country, where lush foliage lends a tropical flair to indoor spaces. Garden centers sell cultivars ranging from robust five-foot-tall specimens to table-top varieties less than 10″ tall.

They like soil that stays lightly moist all the time. But roots that stay wet all the time (from overwatering, overpotting, sitting in a wet saucer, or poorly-drained soil) are unable to “breathe”. Air and water are equally important to root health. Tiny root hairs that absorb moisture rot in wet soil, so the plant can’t get water to the leaves, causing the familiar wilt. A plant can wilt from either dry or constantly wet soil.

 

Keeping the Peace Lily Tidy

Strelitzia

Bird of paradise.

When yellow leaves appear, remove the entire leaf—both the blade (the wide part) and the petiole (the narrow leaf stem). The petiole is connected to the crown, stem, or the main trunk of a plant by a thin layer of cells. That layer of cells, the abscission layer, helps the petiole separate from the main part of the plant if the leaf is no longer useful.

After cutting off most of the yellow leaf, peel off the last bit of the yellow or brown petiole. If it is difficult to remove, as in large cultivars, cut the base of the petiole longitudinally down the center, toward the stem or the crown. Now you can easily peel off each half of the remaining petiole.

This works on other species with strong leaf attachments, such as Bird of paradise (Strelitzia, photo, above), yucca, palm, and dracaena. Removing all those dead fragments greatly improves the plant’s appearance.

Easy to Grow

Peace lilies are not demanding when it comes to light. Provide bright indirect light or morning sun for continuous growth. Disregard the advice that they thrive in “low light”. Sure, they’ll survive for a while, but brighter light toughens the tissues. New growth emerges thicker and stronger.

Plants photosynthesize and grow faster and often bloom in those locations, sometimes emitting a trace of scent soon after the white spathe flowers open. During the shorter days of the year, peace lilies welcome a few hours of direct sun.

When the flower turns brown, snip off most of the stalk, wait a few days, and then pull out the remaining part of the shrinking brown stalk. You could remove it earlier, but sometimes a few green leaves are inadvertently removed at the same time. Once again, this keeps the plant tidy, with no lingering dead remnants.

 

How Often Should I Water My Peace Lily?

The Environmental Variables

diagram, wilted plantTemperature, light, humidity, fullness of the plant (number of leaves), pot size and type (porous or non-porous), soil composition, and air circulation affect moisture in the soil. A furnace cycling on more often during cold weather necessitates frequent watering of thirsty plants. Knowing how these variables work in conjunction with each other, for each species, will determine how often your plant needs water.

A full and potbound (roots tightly filling the pot) peace lily, in morning sun at 72°F, and in potting soil that drains fast (has a lot of bark chips), for example, might need water every 2 or 3 days. On the other hand, one that was recently transplanted into soil with mostly peat moss and kept in a room at 65°, in indirect light, with 15 other plants nearby (higher humidity) might need water every 5 or 10 days. That’s why it’s so difficult to answer the question, “How often should I water it?”

Most varieties of peace lily are potted into 6″ to 10″ diameter pots. Stick your finger into the soil an inch or two down from the surface. If the surface of the soil feels dry, but there’s damp soil below that, the plant does not need water.

Waiting to water your plants until they begin to wilt is not a good idea. Delaying for only one day could cause another leaf to turn yellow. Or the plant will refuse to produce new foliage.

How Can I Tell When To Water?

A better course of action is to feel the moisture in the soil and the weight of the plant and pot. Eventually, you’ll learn to recognize that when it feels “this” dry or light in weight, it’s time to water. Some gardeners rely on inexpensive soil moisture meters, but I don’t consider them to be very accurate.

And water your peace lily thoroughly! Not just a little bit that moistens the top 2″ of soil. Instead, give it enough to moisten the entire root ball. Some water will drain into the saucer, and a dry pocket of soil might soak up that excess. Drain off any excess that remains in the saucer after 15 minutes.

Many of us conserve energy in winter by keeping the thermostat in the mid to high 60’s F during the daytime and in the low 60’s at night. If you’re growing plants from the tropics, they appreciate being given lukewarm water, about 85° or 90°. This includes ficus, philodendron, pothos, African violet, Alocasia, Aglaonema, and spathiphyllum. Dry soil absorbs lukewarm water more readily than it does cold water.

 

Upon Careful Examination

Place a fully wilted peace lily in a bucket filled with lightly warmed water up to the pot’s rim. You might have to weigh down the pot. Keep it there for an hour or two, then let it drain. If it doesn’t revive after a few hours, remove the plant from its pot and examine the roots.

Certain materials used at the wholesale nursery, once dry, can resist absorbing water. It’s possible that, even though the plant had been transplanted into better quality potting soil, the plant’s original root ball stayed dry and was unable to produce new roots. When transplanting any plant, tease out some of the roots on the surface of the root ball, especially one that is solidly filled with roots. This helps stimulate the formation of new roots that will quickly grow into fresh potting soil.

I’ve worked on plants that seemed to have moist soil, yet remained in a wilted state. One of these conditions was usually the cause:

  • The plant was repotted too deeply, rotting the petioles and the crown of the plant. The crown should remain at soil level, where the green top growth meets the roots. Very few plants survive being planted lower in the soil. Rule of thumb: the original soil surface should be visible after repotting.
  • Over time, the organic matter (peat moss, wood products) in soil breaks down and loses most of its volume. Consequently, the soil surface drops lower in the pot. If roots are visible under the crown and are exposed to the air, add fresh potting soil to cover the roots. You might have to remove the plant from the pot and add soil under the roots to raise the crown to the proper level. Either way, don’t bury the crown.
  • The roots were not teased out from the root ball, and remained within the tight confines of the original root ball. The root ball dried out before new roots could grow into the moist new soil.
  • New potting soil was loosely added around the root ball, and not firmed in next to the roots. Moderate pressure against the roots helps develop a healthy root system, and fills any voids in the pot that could dry out delicate root hairs. It also prevents water from rushing through the pot, following the path of least resistance, and not soaking in.
  • The plant’s soil was wet for too long, and the rotted roots couldn’t regrow. Fungal and bacterial pathogens build up in wet soil and cause more problems.
  • The temperature in the room or of the water was too low. 
  • The plant was overfertilized, burning the roots. Many people think that fertilizing more often or using more than the recommended concentration makes plants grow faster. It doesn’t. Overfertilizing makes plants die faster. High salt concentrations draw water out of the roots, killing them.

Many of the problems we have with houseplants can be avoided if we keep them potbound in the winter. Cooler soil temperatures and shorter days do not favor root growth at this time of the year. It’s better to delay repotting houseplants into larger containers, if they need it, until spring to mid summer.

How To Grow Succulents To Perfection!

May23

 

 

Speaking Of Succulents

 

Earlier today, I gave a presentation on succulents at the annual meeting for the Charlotte (NC) Council of Garden Clubs. We spent a few hours at Southern Gourmet in Matthews, and, with their help, and someone else’s laptop, I was able to get through all the pictures. Thank you, CCGC, for the invitation.

What Is A Succulent?

 

Succulents, by definition, are plants that store water in their leaves, stems, and roots. They evolved in arid regions (primarily in the Americas, Africa, and Australia), and can endure intense sunlight and prolonged drought and heat. By providing favorable conditions, we can grow colorful succulents in sunny windows. Over the past several years, they have been enjoying a resurgence in popularity.

Decades ago, I purchased young bare-root succulents from a California wholesaler for my horticultural business. Unwrapping each little parcel was like waking up on Christmas morning as a child. These were plants I’d never seen before—Titanopsis, Pleiospilos, Graptopetalum, Lapidaria—and were destined for sale at the Westover Flea Market when I lived in nearby Morgantown, West Virginia.

Although there are many species of hardy succulents in the Sedum and Sempervivum genera, this article addresses primarily the tender succulents, which require temperatures above freezing.

 

 

Plenty Of Light For Succulents

Adequate light is one of those conditions that must be met for these plants to show good color and characteristic form. Some succulents, such as Haworthia, Gasteria, Aloe, Epiphyllum, and Christmas cacti, grow well with at least 4 hours of direct sun, and very bright indirect light the rest of the day.

Crassula, Echeveria, Euphorbia, and Sedum appreciate even more light, at least 5 or 6 hours.

Cacti (succulents with spines or thorns), living stones, and Sempervivum (Hens and Chicks) need abundant sunshine, at least 6, but preferably 8, hours per day.

Direct sunlight keeps the plants colorful and compact. If the plants receive enough sunlight most of the time, they will tolerate the occasional stretch of cloudy weather without deteriorating.

Artificial light helps during the short days of winter or when the sun refuses to shine. When necessary, I use 2-tube 4′ long shop lights with “daylight” LED or fluorescent tubes. Be sure to place the plants within a few inches of the tubes for at least 16 hours per day.

 

When Light Is Insufficient

 

 

How do you know when your succulents are not receiving enough light? Plants that grow in the shape of a rosette start growing faster (photo above, left). The center leaves outgrow the outline of the plant, stretching toward the light. And the new part of the stem grows thinner. That happens when winter sunlight is scarce, as in this Graptopetalum pentandrum ‘Superbum’ (photo above, right).

In poor light, strong colors begin to pale, and purple, red, or orange highlights fade. New leaves become thinner. The internodes (stem segments between the nodes, where leaves are attached) on younger parts of the plant will lengthen (photos, above); this appearance is diagnostic for low light levels.

There’s a huge difference between “direct sunlight” and “bright indirect light”. A few hours of indirect light offers very little benefit to succulents; they need the strong sun. And, without adequate light, succulents are more susceptible to damage from overwatering.

 

 

More Sun For Cacti

 

 

Cacti also suffer in inadequate sunlight. The spines on new growth grow farther apart.

In upright species, the stem becomes narrower relative to the older part that was growing in good sun. If you see that the top half of a cactus stem is thinner than the bottom half, and the spines are not as closely clustered, the plant is not getting as much sun as it was before. Solution? More sun!

The colorful tops of grafted cacti (photo, above right) lack chlorophyll, and depend on the green stock plant for sustenance. Also, the graft is more sensitive to harsh sun and should be placed in cooler morning sun.

Light And Water

 

Light and water are inextricably linked in plants. When the sun doesn’t shine, photosynthesis, transpiration, and respiration slow down, and soil moisture sits unused around the root system. Play it safe and water succulents only on sunny mornings and when the forecast calls for sunny weather for the next couple of days.

Under normal conditions, allow the soil to dry completely before watering again. Although the soil feels dry on the surface, there’s usually some moisture in the lower half of the root ball.

These plants never need misting. Water that sits on the foliage can initiate rot, so shake it off or use a towel to dry it. Never let succulents sit in a saucer of water.

Although glass terrariums are very popular, I do not recommend succulents for terrariums. Unless the glass container has large openings for heat to escape (photo, above), succulents in direct sun will fry in terrariums! They also rot in high humidity or if there’s the slightest amount of excess water in the soil.

 

 

Pots

Succulents and shallow bowls (Pike’s Nurseries, Matthews NC).

 

Succulents prefer to remain quite potbound, where roots are tightly packed in the pot. Plants in oversized pots are more likely to be damaged by overwatering simply because the greater soil volume holds more water for a longer period of time.

Shallow glazed containers, such as decorative bowls and ceramic bonsai trays, make delightful homes for succulent combinations (photo, below). Include rocks, gravel, and driftwood in these dish gardens to create a natural-looking scene from nature.

Tall glazed pots hold a reservoir of water that probably won’t be used by the plant. More appropriate for succulents, terra cotta (Italian for “baked earth”) pots are porous and help the soil dry faster when water vapor passes through the sides.

Repotting, if needed, should be done early in the growing season so a strong root system can develop before the days begin to shorten in autumn. Growth slows during those months. Always use pots that have drainage holes.

 

 

Potting Soil

 

Fenestraria succulents

The soil used for succulents should be gritty for quick drainage. If needed, amend regular potting soil with perlite, coarse sand, horticultural grit, pine fines, charcoal, expanded rock, or PermaTill. “Cactus and Succulent” soil is available, although quality varies widely among brands.

When repotting, all new soil goes below and around the sides of the root ball, never on top of it. Planting too low in the soil results in rotten leaves and stems.

In their natural environment, certain succulents, such as Haworthia, Aloe, and Gasteria, have contractile roots. If blowing sand exposes the crown or the top of the root system, the roots are able to “pull” the plant lower into the soil. Amazing!

 

Living Stones

The ground-hugging living stones, or split-rock, succulents (photos, below) are extremely sensitive to overwatering. Use small clay pots and very gritty, gravelly soil. There should be only a very small percentage of organic matter in the soil.

These plants are well-camouflaged in their native southern Africa, almost indiscernible from the rocks around them. Some of the genera available for purchase include Lithops, Lapidaria, Gibbaeum, and Conophytum.

 

 

 

Fertilizer

 

Succulents grow slowly, so fertilize only 2 or 3 times during the growing season, from March through October.

Use products formulated for indoor houseplants, with small numbers on the package, such as 8-8-8 or 10-10-10. Those three numbers represent the amounts of nitrogen, phosphorus (phosphate), and potassium (potash) in the product. All products list these three primary macronutrients on the label in that order: N-P-K.

It’s better to underfertilize than to overfertilize, so use a more diluted rate than the recommendation on the label. For succulents, dilute it to half-strength.

Lithops and other living stones are extremely slow-growing, so they’re hardly ever fertilized. Use a very dilute higher phosphorus fertilizer only when the plant shows new growth.

 

Sempervivum (hens and chicks) can be tucked between rocks, and they’re hardy perennials.

 

 

Outdoors For The Summer

Succulents summering outdoors benefit from higher light levels and often take on vibrant coloration. Jade plants (Crassula) develop red margins on their leaves in brighter sun, and Echeveria becomes even more colorful.

Monitor closely during periods of high heat. Above 85° F, provide light shade during the hot afternoon hours. Potted plants are more susceptible to stress from extreme conditions than those planted in the ground.

Transition your plants to outdoor conditions gradually. Give them just a couple of hours of early morning sun or dappled shade for the first few days. A plant that was growing indoors all winter will probably suffer sun scald if immediately placed outdoors in full sun. This hardening off process gives plant tissues time to toughen up so they can withstand more intense summer sun. Sunlight causes the cuticle, a protective waxy layer on the leaf surface, to thicken.

This beautiful variegated succulent, called Kalanchoe ‘Fantastic’, has a variably feathered band of cream between the pink edge and the greenish-gray base of the leaf (photo, below). I’ve had this plant for over a decade, and protect it from dropping temperatures in autumn by moving it indoors well before frost. Stronger sun and more stressful conditions might cause it to turn redder in color. It recovers, though, in less extreme conditions.

Protect your plants from excessive moisture. After receiving some rain, place the dampened succulents under cover. Check to make sure the drainage hole allows water to drain freely.

 

And Back Inside In Autumn

As autumn temperatures fall into the high 40’s at night, it’s time to bring your plants indoors for the winter. The more sensitive types, including Echeveria and Graptopetalum, come indoors before the thermometer drops below 55°. Prolonged exposure to cold, wet conditions will cause succulents to deteriorate, so check the forecast!

 

 

Pruning Succulents

If your plants are growing too large and cannot be accommodated in the space available, consider cutting them back. Stretched-out plants benefit from selective pruning in early summer. New growth will soon emerge.

Cacti can be temperamental, so be careful if you choose to lop off the tops. For cacti, this is best done in late spring/early summer for a full season of recuperation.  Stronger light available in the summer causes the plant to respond with more compact growth. They might grow a few new stems below the cut.

During transpiration, water is “pulled” through the plant’s vascular system from the roots, to the stems, and then through the leaves and out to the atmosphere. This process is the primary manner in which moisture is removed from the soil. Therefore, avoid extensive pruning if any plant was recently watered. Because there’s less foliage on the plant after pruning, the soil stays moist for a longer period of time. Wait a few days, or until the soil is almost dry, before pruning.
