Troubleshooting
Autumn Sage problems — and how to fix them
Autumn Sage (Salvia greggii) 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 waterlogging
The most common cause of plant failure; stems wilt and collapse even in seemingly adequate conditions — always plant in sharp-draining soil and avoid mulching directly against the crown.
Leafhoppers
Small, pale leafhoppers feed on the undersides of leaves causing white stippling; a distinctive silvery mottling of the foliage is the key symptom — remove badly affected leaves and use an appropriate insecticide if infestation is severe.
