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 weedgoats will eat it) and Snow on the Mountain are other names for Bishop’s Weed.
What can I plant with Ajuga?
Don’t be fooled by a plant’s size. Ajugas may be little, but they are strong and hardy groundcovers. They can help with erosion control on a bank or slope, fill in a patchy lawn where grass won’t grow, or simply offer color to shaded areas. They’re also excellent for planting beneath bushes and trees.
Ajugas are very attractive because their leaf color and attractiveness last virtually all year, and they produce blue, purple, or white blooms from spring to summer. Ajuga reptans, sometimes known as carpetweed or bugleweed, is a perennial that thrives in zones 3 to 9.
The lustrous leaves of these evergreen shrubs form dense mats. They can tolerate full sun to partial shade, but full sun brings out the greatest color in the leaf. Ajugas are easy to cultivate in practically any type of soil and prefer a moist, well-draining environment, but they can endure dryness for short periods of time.
Because ajuga spreads through stolons, or horizontal stems that creep along the ground, it’s important to consider where you plant it. This mint family member spreads quickly and can become invasive. Planting too close to flower beds, lawns, or other areas where you’ll have to remove it frequently is a bad idea. If you’re worried that ajuga is an invasive plant in your area, check out the Invasive Plant Atlas.
Plant ajugas when all dangers of frost have passed. Then, spacing the holes 8 to 15 inches apart, dig holes just deep enough for the root balls. Gently loosen the roots of the plants, then plant them and firm the dirt around them. To settle them in and eliminate air pockets, water them thoroughly. Fertilizing ajugas is rarely necessary.
To keep your ajugas from becoming overloaded, you should thin them every three years or so. If desired, divide and replant established clumps in the fall or early spring.
Crown rot is an issue, particularly in hot, humid climates or in heavy soils. It’s easy to notice since the lower leaves have rot and spots on the tops of the plants. Give your plants plenty of air circulation and avoid overfertilizing to avoid this illness. Crown rot has no treatment, therefore if it appears, you’ll have to uproot and destroy the damaged plants. When it’s time to replant, consider a new type of groundcover to reduce the chances of the problem reappearing.
Patches of ajuga will occasionally die. If this occurs, remove the dead leaves but leave the roots in place. In most cases, the plants will return the next year.
Ajugas are low-maintenance plants with good rabbit and deer resistance. They don’t need to be pruned, but if you want them to look a little neater after the blooms fade, mow them using a high setting on your mower.
Try coral bells, hostas, ferns, daffodils, astilbe, forget-me-not, violas, hardy geraniums, and other woodland species if your ajugas are in the shadow.
Can perennials grow through Ajuga?
Bugleweed (Ajuga repens) in full bloom. Three Ajuga species are especially beneficial to gardeners in South Carolina. These plants can grow in any generally well-drained soil, and while they tolerate full sun, they develop more quickly in partial shade. Plant these perennials 6 to 12 inches apart in the spring or early fall.
How do you stop Ajuga from spreading?
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.
Will ground cover kill other plants?
Plants that expand to cover all available soil are difficult to remove from established flower beds. Ground cover inhibits weeds and creates a visual link between other plants, but it must be removed when it grows out of hand or when a gardener wishes to change the look. Mulch can suffocate other plants, and digging it up risks injuring the roots of desired plants. Herbicides that go through plants from their leaves to their roots, known as systemic herbicides, provide a solution, as long as targeted plants are safeguarded when herbicides are sprayed. The greatest control is to spray ground cover in the fall, when plants are storing energy in their roots.
How quickly does ajuga spread?
Ajuga will try to conquer the entire region in its immediate proximity. Although it is an aggressive spreader, it is relatively easy to contain because it spreads over the ground.
It is recommended that you use a shovel or a spade to edge the borders of the territory limit assigned to Ajuga twice a year, once in the spring and once in the middle of summer.
There is no need to be concerned because this plant does not spread quickly; rather, it spreads slowly and steadily.
You should not plant this next to a lawn because grass cannot compete with it and will quickly become overrun, leaving you with an Ajuga lawn rather than a grass lawn.
Can you walk on ajuga?
It’s true that good things come in small packages. Ajuga, for example, grows only a few inches tall but provides a dazzling display of color in your garden. This easy-care walking groundcover plant, sometimes known as bugleweed, is prized for its ability to carpet your yard with colorful foliage over time. Ajuga produces blue, purple, or white flower spikes in the spring above a base of bronze, chocolate, brilliant green, or bicolor foliage. Ajuga grows well in pots as well.
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.
Do animals eat ajuga?
Some ground coverings, like lilyturf, are invasive. Before using these plants, you’ll have to evaluate your worries about deer management against any issues about their invasiveness. These ground covers, like lilyturf, are such fast growth that you may want to keep them in check:
- This invasive plant, also known as ajuga (Ajuga reptans), is not eaten by invading deer, making it valuable for deer management. It blooms in a bluish-purple color. Ajuga may be planted in zones 3 to 10, and it usually stays short, though it does gain a few inches when in flower. Ajuga is a simple plant to growalmost too simple. It may grow in full sun or partial shade, and it doesn’t mind what kind of soil it’s in as long as it has proper drainage. It will grow into a dense mat with both lovely foliage and blooms. However, it will appear all over the terrain, frequently in unwelcome locations.
- Vinca minor, often known as creeping myrtle or periwinkle vinca vine, is a perennial ground cover used as a grass substitute in grassy areas and as a deer deterrent. Creeping myrtle, which grows in zones 4 to 8, requires good drainage. This shade-loving, deer-resistant ground cover is frequently planted under huge trees, where a lawn grass would have quickly died due to a lack of sunshine. The vine of the creeping myrtle grows just 3 to 6 inches above the ground, but its trailing stems with evergreen leaves can reach up to 18 inches in length. As the stems creep along the ground, they root at the nodes and spread quickly to make an attractive ground cover. It’s appealing, but it’s also intrusive. Keep it under control to avoid it spreading to places you don’t want it to. In the spring, the creeping myrtle produces a bluish-lavender flower, which blooms intermittently throughout the summer.
- Deadnettle (Lamium maculatum) and yellow archangel (Lamium galeobdolon) are close relatives. Both are invasive (yellow archangel is the worst culprit), variegated, shade-loving perennials with poor drainage. Landscapers who want to keep deer out can use them. They grow 1 to 2 feet tall with a similar spread and may be cultivated in zones 4 to 9. Deadnettle has purplish or white flowers, whereas yellow archangel has yellow flowers. Both are renowned for their leaves. The leaves of the yellow archangel have a medium green tint with silver splotches. The silver content of deadnettle leaves is higher than the green content. Both are considered good plants for dry shade once established.
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.
