Why is my ajuga dying

ANSWER: Ajuga (Ajuga reptans) is prone to a fungal root and crown rot caused by the Southern blight fungus (Sclerotium rolfsii). For this reason we tend to restrict ajuga plantings to small, minor areas that will not be too great a loss should this disease hit. Remove all of the diseased plants and dispose of them.

Why does my ajuga keep dying?

ANSWER: This is crown rot, a common problem of ajuga in Louisiana. The fungus attacks very suddenly, causing plants to collapse, wilt and die. Gardeners sometimes use the term "melting out" to describe this condition. This disease, caused by Sclerotium delphinii, is the reason we use ajuga only in limited areas.

Does ajuga need a lot of water?

Soil and water: Soil should be moist, though ajuga plants are adaptable and can even be drought-tolerant. These plants are able to sustain themselves on normal rainfall, though watering may be necessary for times where it is particularly dry or if your plant is located somewhere with full sun exposure.

How do you treat crown rot in ajuga?

The only chemical we can recommend for homeowner use is thiophanate methyl. This chemical will protect healthy plants but will not eradicate the fungus. Disease management includes removing and discarding infected plants and the soil immediately surrounding the rootball.

Will ajuga come back?

The plants will often come back in the following year. Ajugas are low-maintenance plants that have good resistance to rabbits and deer. They don't require pruning, but if you want to make them look a bit neater after the blooms are finished, mow over them with your mower on a high setting.

How often should you water ajuga?

Water. Unless it's really dry, ajuga can usually sustain itself with normal rainfall. Water weekly while plants are getting established, then once every 2 to 3 weeks.

Why is my ground cover dying?

This is the result of frequent rains, overhead watering, crowded plantings, and heavy shade. They are often grown in less than optimal conditions where other plants won't grow. Plants grown in a stressful environment are more prone to disease. Fallen leaves from overhead trees are often left on top of ground covers.

Can ajuga tolerate full sun?

These species grow in any reasonably well drained soil and although tolerant of full sun, growth is more rapid in partial shade. Plant these perennials in spring or early fall 6 to 12 inches apart. Mow or trim away old flower spikes.

What causes crown rot in ajuga?

Crown rot, sometimes called southern blight or southern stem rot, is caused by several soil-borne fungi. It affects herbaceous plants and some woody plants but is most commonly found on ajuga, anemone, campanula, chrysanthemum, delphinium, hosta, hydrangea, iris, narcissus, phlox, rudbeckia, scabiosa, sedum, and tulip.

Why are my ajuga leaves turning yellow?

Sudden wilting, yellowing and death of ajuga, also known as bugleweed, means crown rot may have invaded the planting. This fungal disease is most common in warm wet or humid weather. It first appears as sudden wilting and dieback in colder climates and yellowing and death of plants in warmer areas.

Does ajuga like wet soil?

Ajuga does best in well-drained, moist soil, but it can handle drought and dry soil.

Can ajuga tolerate wet soil?

It is native to Europe, northern Africa, and southwestern Asia. Its compact, dense mat has beautiful small clusters of purple flowers which appear in mid to late spring. It tolearates all light levels and is an excellent choice for moist areas, although it will tolerate moderately dry soils.

What does crown rot look like?

Gardeners often become aware of a root/crown rot when they see above ground symptoms of the diseases. Affected plants are often slow-growing or stunted and may show signs of wilting. Often the canopy of an affected tree or shrub is thin, with foliage that is yellow or red, suggesting a nutrient deficiency.

Can you come back from root rot?

Once root rot is identified, you must determine if the plant can be saved. If the entire root system has already become mushy, it is too late to save the plant. However, if some healthy, white, firm roots exist, try to bring the plant back to good health by replanting in fresh soil with good drainage.

Can plants recover from crown rot?

Often, the plant will continue to grow and develop despite infection due to the generation of new nodal and brace roots. Some may say that the plant “outgrows” crown rot. The new roots continue to provide access to additional moisture and nutrients, and the plant survives, albeit with a reduced vascular system.

Can ajuga take full shade?

While this plant can tolerate sun, it also does very well in the shade, making it perfect for those areas in your landscape with too little sun for turf. It forms a dense, low-growing evergreen ground cover with dark green to purple foliage.

How do you take care of an ajuga plant?

Once established, ajuga plants requires little care. Unless it's really dry, ajuga can usually sustain itself with normal rainfall and there's no need to fertilize this plant. Of course, if it's located in the sun, you may need to water it more often.

Can ajuga grow in shade?

Ajuga is a great groundcover for creating color in moist shade. Ajuga, also known as "Carpet Bugleweed," is a small, spreading evergreen plant that many gardeners love. Its beauty lies in its waxy, weed-suppressing foliage that spreads eagerly, even in the deep shade where grass won't grow.

How do you encourage ajuga to spread?

All you have to do is dig out the clumps and pull or cut them apart into smaller sections, then replant them in another location. You can also simply cut out big sections of plant mats – like lawn sod – and move them to a new location.

Does bugleweed grow back?

This low-maintenance perennial is grown for its colorful foliage and groundcover habit. In the spring, it produces profuse blue flower spikes about 6" tall and it may sporadically bloom again throughout summer and into fall. Bugleweed's flowers are breathtaking when planted in mass.
