Downy Yellow Violet problems — and how to fix them
Downy Yellow Violet (Viola pubescens) 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
Powdery white coating may appear on leaves in warm, dry conditions with poor air circulation; improve spacing, avoid overhead watering, and remove affected foliage promptly.
Viola gall midge (Dasineura affinis)
