Narrow-leaved Sage problems — and how to fix them
Narrow-leaved Sage (Salvia stenophylla) 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 from overwatering
The most common cause of death; plants wilt, leaves yellow, and stems collapse at the base — always err on the side of underwatering and ensure pots have drainage holes.
Powdery mildew
White fungal coating on leaves in humid or sheltered conditions; thin out congested stems and treat with a sulphur-based fungicide if severe.
