Hairy Violet problems — and how to fix them
Hairy Violet (Viola hirta) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
Dry roots combined with humid air encourage powdery mildew on the hairy leaves; improve air circulation and water at the base rather than overhead.
Vine weevil
Larvae eat the roots and crown of container-grown plants; check root balls when repotting and use a biological nematode drench (Steinernema kraussei) in late summer.
