Ajuga Ground cover
The subject ground cover was planted 3 weeks ago. It was just discovered that there are holes in some of the leaves. Is something attempting to eat these leaves? I use to have Hostas planted in the same spot and had the same type of holes, which I assumed were made by slugs. Please advise what you think and if it is happening by some insect, and what do I do to control this problem?
Yes, it sounds like Slugs.
