Daghestan Sage problems — and how to fix them
Daghestan Sage (Salvia daghestanica) 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.
Winter crown rot in wet soils
The primary killer of this plant in UK and Pacific Northwest gardens; plant in very well-drained gritty soil on a slope or raised bed, and avoid mulching directly over the crown where moisture can accumulate.
Powdery mildew in humid summers
The silver-felted foliage can develop powdery mildew in still, humid conditions; ensure good air circulation and avoid any overhead irrigation.
