Kudzu, sometimes known as “the vine that ate the South,” was imported from Japan in 1876 to embellish the Japanese Pavilion at the United States Centennial Exposition in Philadelphia. The fast-growing vine was widely planted as a high-protein animal feed crop and to avoid soil erosion. Kudzu escaped cultivation and now covers millions of acres in the southeast, swallowing trees, buildings, and anything else that gets in its way.
Even if they could locate it for sale, most Southerners are aware of kudzu’s invasiveness and would not deliberately grow it. Other potentially invasive plants, on the other hand, are freely available. Non-native plants such as English ivy (Hedera helix), bugleweed (Ajuga reptans), and periwinkle (Vinca minor) were brought to the United States as ornamentals. They’ve escaped into woodlands and fields across the country, where they produce dense evergreen mats that drown out natural flora.
Will bugleweed spread?
Ajuga reptans, sometimes known as carpet bugleweed, is a prominent ground cover. It spreads rapidly by runners, forming a mat of dark green leaves 2 to 3 inches across in full sun and 3 to 4 inches wide in part shade. In full sun, selections with bronze or metallic-tinted leaves hold their color the best. The flowers, which are usually blue, are borne on spikes that are 4 to 5 inches tall. Early May to mid-June is when the plant blooms. Set aside established plants in the spring and they will cover the soil in one growing season. Plants should not be planted too deeply. It’s never a good idea to hide the crown. Runner plants can be dug out and replaced in the spring or early fall from established plantings.
Ajuga genevensis (Geneva carpet Bugleweed) is a perennial rock garden plant that grows 5 to 14 inches tall. It has grayish, hairy stems and coarse-toothed leaves up to 3 inches long that do not spread via runners. Blue flower spikes are the most common, but rose and white varieties are also available. Because it spreads more slowly than A. reptans, this upright species is gaining popularity. It is more sun tolerant than other Ajuga species.
Ajuga pyramidalis (Upright Bugleweed) is a 2 to 10 inch tall erect plant. Runners are not involved in the propagation of this disease. Many roundish, 11/2 to 4-inch long leaves grow from the stems, which contain long grey hairs. The huge purple bracts appear to press against the blue blooms on the flower spikes, which are 4 to 6 inches long.
How do you keep bugleweed from spreading?
Bugleweed grows best in a rich, wet, well-drained soil, but will withstand clay and poor soils. Plant in full sun to create a shady environment. If you’re going to plant bugleweed near to a grass area, bear in mind that it has creeping tendencies; use edging to keep it from spreading. Run a lawnmower over spent flowers to deadhead them. Seed, cuttings, or division are all methods of propagation. To avoid crowding, division can be done at any time of year and should be done every two to three years. There are no major pest or disease problems; nevertheless, crown rot can occur in hot, humid conditions or in locations with inadequate air circulation.
Will bugleweed kill other plants?
There’s no doubting that Bishop’s Weed in variegated form is a lovely plant. It thrives in shady areas where splotches of white are needed to liven things up. But you’ll never be able to enjoy just a smidgeon of Bishop’s Weed. Its roots form a dense mat as it grows, suffocating any neighboring vegetation. While this may sound like a good way to keep weeds at bay, it will eventually take over your garden plants as well.
Bishop’s Weed was initially labeled as invasive in Rhode Island in 1863, although you can still get it for sale. You may probably determine it’s a member of the carrot family by looking at the white, umbel blossoms, which look a lot like Queen Anne’s Lace. The plant does attract helpful insects, so it has some virtues, but it is simply the incorrect plant for many situations.
If you’ve already planted Bishop’s Weed and regret it, the best way to get rid of it is to use up all of your resources. In the early spring, cut it as short as possible and cover the area with plastic. The plants are unable to photosynthesize, receive insufficient water, and are overheated. They ultimately give up, even if it takes a long time.
Goutweed (a mashup of goat weed—goats will eat it) and Snow on the Mountain are other names for Bishop’s Weed.
Should I get rid of bugleweed?
A few sprigs of bugleweed on your lawn may give a splash of color, but the invasive perennial weed may quickly take over as your yard’s dominant ground cover. Bugleweed, also known as ajuga, is a tenacious weed that thrives in temperate areas, and eradicating it is critical for the health of the rest of your garden or lawn plants. Before you go for a chemical herbicide, consider less harmful alternatives for eradicating the invasive weed.
What do you do with bugleweed?
Bugleweed is one of the easiest plants to divide and propagate. Underground runners develop bunches around the parent plant, allowing it to spread. You can dig up and transfer these clumps when they become too congested. It’s better to do this in the spring or fall, when there’s little risk of frost.
What is bugleweed good for?
Bugleweed is a type of flowering plant. Medicine is made from the components that grow above ground.
Bugleweed is used to treat excessive thyroid hormone levels (hyperthyroidism). Premenstrual syndrome, breast pain, agitation, difficulty sleeping (insomnia), and bleeding, particularly nosebleeds and excessive bleeding during menstruation, are also treated with it.
How does it work?
Thyroid hormone synthesis may be reduced by bugleweed. Bugleweed also appears to inhibit the production of the hormone prolactin, which may aid in the relief of breast pain.
How do you get rid of common bugle?
Don’t put the plants in your compost pile; they’ll take root and you’ll be right back where you started – or worse.
Making a DIY, ecologically friendly pesticide by mixing equal parts very hot water and vinegar is another technique for getting rid of bugleweed. Add a pinch of salt and a few drops of liquid dish soap to the mix. Use a spray bottle or a garden sprayer to apply the solution.
If your grass doesn’t have ajuga, you might be able to smother huge portions with black plastic. Leave the plastic secured with bricks or boulders for two weeks to allow the sun to “bake” the ajuga. Leave the plastic in place for another two weeks if the plants are still alive.
Chemical herbicides – If all else fails, a chemical herbicide may be required for ajuga weed control. If you have ajuga in your lawn, read the label carefully and apply a non-selective herbicide that will kill the ajuga while leaving your lawn unharmed.
Chemical management should be utilized only as a last resort because organic methods are more environmentally friendly.
How do you control an Ajuga ground cover?
Using impermeable black plastic sheeting, cover huge portions of ajuga to be removed (weed mulch or heavy garbage bags). Leave the area alone for at least four weeks after anchoring it with rocks. This deprives the plant of both light and water, severely limiting its ability to thrive.
Is Carpet Bugle an invasive plant?
The Invasive Plant Atlas of the United States lists Ajuga reptans (Carpet Bugle).
Invasive species have led to the extinction of 42 percent of U.S. endangered and threatened species, and 18 percent of U.S. endangered or threatened species, according to the US Forest Service. Invasive plants compete directly for moisture, sunlight, nutrients, and space with native species. They dispense with and change natural plant populations, harm wildlife habitat and water quality, and may contribute to soil erosion.
According to the federal government, roughly a quarter of the 20,000 plant species native to North America are endangered, with many of them owing to habitat degradation. Planting beautiful native plants in your garden will assist to counteract this tendency.
A plant is said to be native if it has evolved organically in a certain region or environment without the intervention of humans. Growing native plants has numerous advantages. For starters, these plants have better soil, moisture, and weather adaptations than exotic plants from other regions of the world. They require fewer fertilizers, herbicides, and water. Second, they are unlikely to become invasive and ruin natural habitat if they escape. Third, unlike invasive plants, they benefit wildlife by providing refuge and food for native birds and insects.
What ground cover is not invasive?
It’s past periwinkle (Pachysandra terminalis), English ivy (Hedera helix), and Japanese spurge (Pachysandra terminalis) for American gardeners (Vinca minor). True, these common landscape plants make great evergreen groundcovers, creating dense expanses of attractive leaves quickly. However, they are a nuisance outside of cultivation, invading natural habitats and outmuscling native plants with their vigorous growth. (Invasive plant lists for much of the southern and far-western United States include English ivy and periwinkle.)
Many Americans share the same qualities as the omnipresent three, but without the drawbacks.
Here are a few beautiful natural, evergreen alternatives to invasive spreaders.
