The Q&A Archives: Ajuga Died Out

Question: I had a very nice garden full of Ajuga -- it showed signs of distress late in the summer and early fall. Last year at this time, it was in full bloom. I have nothing this year -- disease? soil? fungus? I hate to replant if I will lose it all again.

Answer: Ajuga, or Carpet Bugle, is one of the most carefree and attractive groundcovers around. It is generally without problems, except where soil is poorly drained. With wet feet, it can develop crown rot. Sclerotium delphinii is the fungus that enters the plants through the roots and crowns and cuts off the water supply. The most striking symptoms are wilting and yellowing of the leaves. Badly infected plants can be easily pulled up and will show damage to the root system and crown. The fungus can remain in the soil, so it's not a good idea to replant Ajuga in the bed. It's important to improve the drainage prior to planting anything in the bed.
