Troubleshooting
Greek Sage problems — and how to fix them
Greek Sage (Salvia fruticosa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root and stem rot
Overwatering or heavy, wet soil quickly rots the woody base; plant in gritty, free-draining soil and water sparingly.
Frost damage
It is only borderline hardy and suffers in hard frost; overwinter in pots under cover or protect the base with mulch in marginal climates.
Leggy, woody growth
Plants grow bare and sparse at the base without pruning; trim lightly after flowering each year, cutting into green wood rather than old bare stems.
Powdery mildew
Mildew develops on foliage in humid, still or crowded conditions; ensure full sun, airflow and dry leaves to prevent it.
