Grape-Scented Sage problems — and how to fix them
Grape-Scented Sage (Salvia melissodora) 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
Hairy foliage is susceptible in humid, still conditions; plant in open, breezy positions and space adequately to maintain airflow around the canopy.
Frost damage
Stem tips die back in sharp frosts; in borderline climates mulch the crown heavily with bark or straw in autumn and cut back dead growth in spring.
