Long-stamen Sage problems — and how to fix them
Long-stamen Sage (Salvia stamina) 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
Appears as white, powdery patches on leaves in humid or shaded conditions; improve air circulation and avoid overhead watering to reduce incidence.
Root rot
Caused by overwatering or poorly drained soil; plants wilt despite moist soil and stems collapse at the base — improve drainage immediately and allow soil to dry.
