Troubleshooting
Field Sage problems — and how to fix them
Field Sage (Salvia campestris) 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.
Crown and root rot
The most common cause of failure; occurs when the plant sits in wet or poorly-drained soil, especially over winter — sharp drainage and raising the crown slightly when planting prevents this.
Powdery mildew
Can occur in warm, humid conditions with poor air movement; improve spacing and ventilation; in most cases plants recover without treatment once air circulation improves.
