Mountain Desert Sage problems — and how to fix them
Mountain Desert Sage (Salvia pachyphylla) 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 in wet soils
The single greatest threat; poorly drained or clay soils, or excessive irrigation in winter, cause rapid crown and root rot — sharp drainage and a dry winter rest are essential.
Woody dieback without pruning
Without annual pruning after flowering, the plant becomes excessively woody and open; cut back by one-third in early autumn to maintain a compact, vigorous habit.
