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.
Do you cut back Ajuga after flowering?
After the blooms have finished blooming, cut the ajuga down to 1 to 2 inches above soil level. Hand-cut the spikes using pruning shears, or mow over the patch with a lawn mower.
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.
Does ajuga choke 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 weedgoats will eat it) and Snow on the Mountain are other names for Bishop’s Weed.
Seeds
Planting seeds is one technique to begin propagating ajuga plants. Sow ajuga plant seeds in containers in the fall or spring if you chose to do so. Simply apply a small layer of compost to the seeds and keep the soil moist.
In a month or less, the seeds germinate. Individual plants should be pricked out and placed in larger containers. Move the young plants to your garden beds in the summer.
Division
Stolons, which are underground runners, spread Ajuga. The plant is rooted in neighboring soil by these runners, which create clumps. The ajuga clumps will soon get overcrowded, and their strength will wane. Now is the moment to lift and divide them so that you can have more ajuga plants.
Ajuga division propagation is best done in the early spring or late fall. It’s a straightforward procedure. Simply dig up the clumps, pull or chop them apart into smaller portions, and transplant them in a different spot.
You may also just chop away large portions of plant mats similar to lawn sod and relocate them.
Can you grow ajuga in pots?
Ajuga is one of my favorite plants for pots and garden beds. It is resilient, fuss-free, and produces a large number of plants each season. Ajuga cultivated in containers is just as beneficial and brightens up a pot when other plants haven’t bloomed or have faded back. The vibrant color and cheerful small flowers can thrive in either shade or sun, giving you a variety of container alternatives for any setting.
Gardeners who enjoy ajuga in the garden will be pleased to learn that the plants can also be grown in limited pots. Even runner plants will flourish in a well-drained medium with plenty of organic matter.
Green leafy specimens and blooming perennials that haven’t blossomed yet will benefit from the splash of color and modest growth habit. Ajuga doesn’t compete with the brilliance of other plants once your container is fully bloomed. Instead, it draws attention to the tones and textures that are becoming more prominent as spring gives way to summer. The optimum season to grow ajuga in pots is in the spring, but in temperate climates, the plant can also be used to create a container garden in the fall.
Does ajuga grow in shade?
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. Remove old flower spikes by mowing or trimming them.
Can you eat ajuga?
Ajuga reptans – Bugle: The grass would have to be allowed to grow a little longer than usual for this to work. It thrives in moist, partially shady environments, and the young shoots can be eaten raw in salads. The young leaves can be eaten raw or cooked, and the root is edible but bitter.
