A New Home and New Gardens!

As you might know from reading The Farm In My Yard, I moved from Rockville, Maryland to Charlotte, North Carolina in 2013. I worked for a few years, while watching over my elderly mother. After she passed away in 2020, the search was on for a larger property in a smaller town. Must-haves included reasonably quiet surroundings, lots of nature, room to play in new gardens, and no HOA. This article includes information from a landscaper’s perspective that might help first-time property owners.

Success! In late October, I moved to a new home in northern North Carolina. A few obstacles didn’t stop my tireless realtor, Erika, from finding this (almost) perfect little house. There was Covid, for one, and the reluctance on the part of homeowners to list their homes for sale. Very few livable offerings in my price range came to the market. As soon as they did, they immediately went under contract.

As many buyers have done in this tight market, I made an offer on the property sight unseen. Well, truthfully, I did drive by the house before submitting an offer, and liked what I saw. Trees, woods, space, and sunlight—perfect for a gardener! The previous owners made some major improvements, saving me the trouble and the expense. But I had no idea what the interior looked like.

 

Inspections

When buying a house, have all the inspections done before closing, as recommended by your realtor or for your own peace of mind. Estimate the cost of necessary upgrades and repairs.

Particularly for older homes, check the roof and electrical, plumbing, and HVAC systems. Look for water damage and mold, pests and wood rot, foundation issues, adequate insulation, storage space, and evidence of ongoing maintenance.

Negative findings could nullify a contract or provide a basis for negotiation between your realtor and the listing agent.

 

 

The Lay of the Land

 

Small towns, farms, and independent businesses dot the landscape in this part of Wilkes County. Several vineyards and state parks attract visitors to these lovely rolling hills, and rivers offer lots of sporting opportunities. Drive along any of the scenic roads, and new vistas open at every turn; the Blue Ridge Parkway is only half an hour away. Beautiful countryside!

My new home, a one-story house built in the 1940’s, sits on 1¼ acres of mostly level land. The view from the front porch looks over a field, a few houses, and downslope toward a small stream. Stunning sunrises greet me from that direction almost daily.

Most of the trees’ leaves have fallen from the massive limbs of the native white and willow oaks (Quercus alba and Q. phellos). A few of these trees tower over the eastern border of the property. In the summer, those toward the west will shade the house from hot afternoon sun.

The mighty oaks came first, judging by their size, and then the house. If I were to name the property, Quercus Magnus would seem fitting.

 

Preliminary Plans for New Gardens

There’s plenty of space for the berries and the vegetables to bask in the sun. Plenty of space to raise shade-loving perennials in the fenced enclosure north of the great oaks. And plenty of space for gardens that will support birds, bugs, bees, and butterflies.

Also, importantly, there’s room to grow plants to sell at the local farmers’ markets, as I did in Maryland for 25 years.

 

 

After Moving In

 

Deciding what to do first depends on the season, your climate, and the condition of the house and gardens. Priorities often reflect our occupations or interests, so artists might first set up a studio while contractors organize tools in the outbuildings. Growing families might rank bicycle storage, a big kitchen, and an extra bathroom at the top of the list.

And gardeners? Well, we look at soil quality, existing gardens, and sunlight. This gardener prefers a large, mostly blank slate. Others call it a lawn.

In April, I’d be concerned about starting seeds for the market, getting the summer vegetables and flowers planted, and cutting grass. But it’s December now. The yard needs tidying, houseplants need to find their homes, and, of course, we must bake Christmas cookies. Not to mention, those boxes won’t unpack themselves!

Moving into a house that doesn’t need major repairs eases the stress. To be sure, there are some improvements that can and will be made, but nothing that needs immediate attention. Wouldn’t mind a new kitchen with a dishwasher, Santa. (Chocolate chip or almond crescents?)

 

 

Trees and Shrubs

 

Poor Pruning Practices

Walking around the property will highlight issues that need attention. Check the trees and shrubs for dead or broken branches or call a licensed arborist for a professional assessment. There are some dead twigs way up in these oaks. A brisk wind shakes them loose, so the truck stays parked under the carport. Fortunately, that debris falls short of the house.

 

 

I’ll hire an arborist to clean up the trees and remove branches that have been headed back. Heading back, or bluntly cutting off the end of a branch, causes many epicormic shoots to form. Those are new growing tips emerging from buds concentrated close to the cut. The shoots also can cover the length of the branch. Epicormic shoots have weak connections to the branch, and, over time, most will fail and fall from the plant (photos, above).

Similarly, topping trees is, in my opinion, not recommended. Yes, it reduces the height, temporarily, but topped trees in winter are hardly natural-looking and not attractive (photo, below). They, too, drop twigs over an extended period of time.

An expert arborist might be able to undo the damage from heading back or topping. However, removing the tree might be the most economical solution. Research appropriate tree species for your property and where to plant them. Keep in mind that plants almost always achieve dimensions larger than those indicated on the label. Your local agricultural extension office can help. Check with botanical gardens and sources such as your state’s native plant societies.

The Root of the Problem

Trees planted close to the foundation can threaten its structural integrity. Consider having them removed.

The same ruthlessness applies to the wrong tree in any space. Keeping silver maples or weeping willows close to the house, septic system, or underground utilities begs for trouble. This is where an arborist or a well-informed landscaper can recommend more fitting species and a pleasing design for better curb appeal. Call 8-1-1 to have underground utility lines marked.

 

Constricted

Look for old stakes and wires still looped around trunks or branches. Wooden posts rot, but wire and synthetic rope from clotheslines, fences, and hammocks persist.

As trunks and branches grow in girth, they attempt to grow around the obstruction, usually cutting off the vascular system inside the bark. This results in the death of those parts of the tree that cannot receive water from the roots. Early fall color on isolated branches might indicate trouble, such as pests or physical constriction.

In the Maryland garden, a dogwood tree died for no apparent reason. After cutting it down and opening the bark in several places, I found plastic rope deeply embedded in the trunk a few feet from the ground. Although the damage appeared several years after I had moved there, it eventually killed a beautiful dogwood.

 

Flares and Girdling Roots

 

 

Most trees flare out where the trunk descends into the ground. If this flare is missing, see if soil has been piled up against the trunk, and remove it.

Construction around unprotected trees can deposit soil that cuts off the oxygen supply to the roots, resulting in the plant’s decline. As little as an additional 1-2″ can damage trees. Also, parking vehicles over the root system compacts the soil, impeding air and water penetration. Keep in mind that tree roots extend well beyond the dripline, or the edge of the canopy.

Check for a girdling root crossing over the trunk at the soil line or below it. As it grows, the root will hinder growth of that section of the trunk, making the trunk look straight-sided where it enters the ground. Cut it out before the tree tries to grow around it. Maples and other surface-rooting trees are notorious for this.

There’s no flare at the base of this maple tree (photo, above) and at least one large girding root is constricting the flow of water and nutrients from the soil. I noticed large dead limbs in the canopy, so the tree might be removed.

 

English Ivy

Vining English ivy (Hedera helix) is growing up a white oak’s trunk, using rootlets to cling to the bark. All the vines will be removed for 4 main reasons.

red-shouldered hawk dec 2021First, English ivy is a woody vine, so its stems will grow in girth just as a tree branch does. As they wrap around the tree trunk or the limbs and thicken over the years, the ivy stems will constrict tree growth, killing limbs and possibly the tree.

Second, the evergreen ivy holds moisture and debris close to the bark, and could encourage insects and diseases.

Third, as ivy scampers over the ground and up the trees, it provides safe haven for rodents. Birds of prey and other predators cannot see them. Here’s a red-shouldered hawk perched in a dogwood tree, looking for dinner.

Fourth, ivy competes with small native plants, crowding them out.

So, the ivy must go.

A Passion For The Gulf Fritillary Butterfly


2019

Updated 9/12/2024

 

 

The Gulf Fritillary Butterfly

At the Hendersonville Garden Jubilee in May, I bought a small Passiflora vine as a gesture of support for Bee City USA. One third of the food we eat and 80% to 90% of all flowering plants rely on pollinators to set fruit and, therefore, to reproduce.

Bees are efficient pollinators, but other insects and animals, including butterflies, beetles, moths, bats, and hummingbirds, also provide this service. This article concentrates on attracting the gulf fritillary butterfly to your garden.

Passiflora incarnata

 

Planting the passionflower vine had to be delayed until late summer, after the siding replacement had been completed. And then the plant took off! 

Passionflower vine (Passiflora incarnata), also called maypop, is the primary food source for larvae of the beautiful gulf fritillary butterfly. This herbaceous perennial is native to the southeastern quadrant of the U.S., in USDA zones 5 to 9. A substantial vine, growing to 20′ in length, it blooms from late spring to late summer. Its pale purple 3″ flowers yield kiwi-size yellow-orange fruits from which you can make jams and jellies, although I haven’t tried it.

Other species of Passiflora can host larval fritillary populations, but some are toxic and will kill the caterpillars. So, choose carefully! Usually, the female senses chemicals with her antennae and determines suitability of a particular plant for oviposition (depositing the eggs).

Passionflower vines also host the variegated fritillary, the Mexican fritillary, the Julia butterfly, and the zebra longwing. I was hopeful but not overly optimistic that the caterpillars would show up this late in the season. But I have since learned that caterpillar activity of the gulf fritillary ordinarily takes place in late summer.

 

 

If You Plant It, They Will Come

 

It wasn’t long before the vine had wrapped its tendrils around the coleus and the Salvia coccinea planted only 2′ away.

I saw the bright orange butterflies a few times this summer, flying around the gardens. But now they visited the vine almost every day to lay eggs, and then the nearby hanging basket of flowers to sip nectar. Adults feed only on nectar, including flowers of lantana, zinnia, Buddleia (butterfly bush), salvia, and Liatris.

Soon, holes appeared in the leaves…already?…and then bigger holes. Success! Long gone are the days when I would have implemented measures to “remedy” this behavior.

Close inspection revealed several orange caterpillars with purplish stripes and black bristly projections. Then more appeared, wave after wave, as the older ones matured and crawled away to pupate. I would not have thought that a plant this small could sustain more than 40 caterpillars over a few short months. But it did, although some chrysalises have succumbed to a fungal disease. Recently I noticed more small caterpillars, even though we’ve already had a light frost.

Thank goodness, I thought, because this Charlotte NC garden isn’t large enough for this vigorous vine. These caterpillars and their voracious appetites help keep this young plant in bounds. The plan is to dig it up and to transplant it to a bigger garden when I move. All of it will be removed, or it will take over the neighbors’ gardens as well. The vines had no trouble growing under the sidewalk and emerging several feet on the other side.

***Update***: Since planting the passionflower vine (in northwest NC) at the edge of the woods almost 3 years ago, it has spread to cover the ground 20′ around the trellis. In 2023, I saw several male gulf fritillary butterflies, but no females. This year, we have both males and females and plenty of flowers for the pollinators, but no caterpillars yet. Rocky clay soil and mowing confine the spread of the vines. 9/12/2024

 

 

Life Cycle of the Gulf Fritillary Butterfly

Gulf fritillaries (Agraulis vanillae) are commonly found in open sunny habitat, grasslands, woodlands, fields, and in gardens. These subtropical butterflies range from Texas to Florida and migrate north from Missouri to Delaware. This butterfly is also found in Central America and in Hawaii.

The gulf fritillary and the zebra butterflies belong to a group called the longwings (Heliconiinae). Larvae of both species feed on passionflower vines. Although the gulf fritillary resembles other fritillaries, it is, in fact one of the longwings. Other fritillary larvae (meadow and great spangled) feed on wild violets.

Predators avoid longwing butterflies due to several odorous chemicals produced in abdominal glands. Passionflowers contain poisons (alkaloids, cyanogenic glycosides), which are picked up by the caterpillars as they feed on the leaves. These chemicals make them distasteful to birds and other animals, but less so in the gulf fritillary.

After mating and consuming protein-rich pollen for several days, the female butterflies lay eggs on passionflower vines. This caterpillar prefers mature foliage, if it is plentiful, leaving other butterfly caterpillars to feed on the young leaves at the tips. I’ve read conflicting information, which states their preference for the young growth tips of the vines. There, the plant doesn’t produce nectaries on its foliage, which attract ants that defend the plant from butterflies and larvae.

Adults measure about 2½” to 3½” wide, with females being larger and a bit darker than the males. Females also have more pronounced markings, and both have white spots on the undersides of their wings.

 

Eggs and Larvae

 

 

Eggs are yellow when first laid. They hatch in 3 to 8 days, depending on temperature.

The caterpillar feeds on foliage and molts 4 or 5 times over the next 11 to 20 days. Then it crawls to a suitable point of attachment for its chrysalis.

 

Pupae of the Gulf Fritillary Butterfly

For 5 to 12 days, according to the websites I read, the caterpillar pupates. But the chrysalis by the front door has been hanging around for at least 2 weeks. It is alive; it reacts when I nudge it. A small sign just under the doorbell, where the pupa resides, requests “Please Do Not Disturb.”

The small chrysalis, at only 1 1/8″ in length, could easily be mistaken for leafy debris. But hanging on the door trim or on the shutters, it becomes conspicuous. In fact, the first chrysalis I saw, also on the door trim, had been partially eaten, probably by a resident lizard. Although I’m tempted to move them to the shrubs to “save” them, it’s better to let nature decide. If this were a rare species, I might think differently. (***Update***: Well, someone dined on this chrysalis, too! 11/2019.)

 

 

Mature Butterflies

Adults typically live for a few to several weeks in warm weather, and longer in cooler temperatures. This butterfly prefers warmer regions, and dies when it gets close to 20°F.

The gulf fritillary butterfly can produce several generations per year in warm winter zones.

Typical Butterfly Life Cycle

 

The typical life cycle of a butterfly:

  • starts as an egg,
  • which hatches into a caterpillar (the larval stage),
  • which pupates in the chrysalis (the pupal stage), undergoing metamorphosis,
  • and then emerges as the adult butterfly.

The gulf fritillary overwinters in cooler zones as adults. Do them a big favor and build a brush pile where they can find shelter in cold and inclement weather. Simply stack piles of twigs, branches, straw, and weeds, and let fallen leaves blow in. Birds, insects, and other creatures will appreciate this kind gesture. And you’ll get some compost out of it.

I give the results of this small experiment Four Stars, an A+. As I mentioned earlier, I was pleasantly surprised by how readily the butterflies found the passionflower vine, and by the number of caterpillars feeding from it. If you’ve been considering what to plant to attract pollinators or pretty butterflies, you won’t go wrong with this one. Just give it time and some space!
