Troubleshooting
Roundhead Prairie Clover problems — and how to fix them
Roundhead Prairie Clover (Dalea multiflora) 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.
Root rot in wet soil
The most common reason plants fail in gardens is heavy or poorly drained soil — crowns blacken and collapse. Remedy by transplanting to a raised bed or gritty slope; there is no fungicide substitute for correct drainage.
Powdery mildew
White powdery coating appears on leaves in humid summers with poor air circulation; improve spacing and avoid overhead irrigation. Plants typically regrow cleanly after cutting back affected stems.
