Opposite-Flowered Sage problems — and how to fix them
Opposite-Flowered Sage (Salvia oppositiflora) 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.
Frost damage
Any frost will blacken stems and kill the plant; bring indoors or take cuttings before the first autumn frost, and do not plant out until all frost risk has passed in spring.
Root rot from overwatering
Soggy compost, especially in cool winter conditions, causes rapid root and stem base rot; always use containers with drainage holes and allow compost to partially dry between waterings.
