Hairy Sage problems — and how to fix them
Hairy Sage (Salvia pubescens) 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.
Fungal leaf spots
Dark spots on leaves develop in wet, humid conditions or following overhead watering; improve air circulation, water at the base only, and remove affected foliage promptly.
Whitefly infestation
Clouds of tiny whiteflies can colonise the undersides of leaves, weakening plants; spray with a fine water mist or insecticidal soap and yellow sticky traps help monitor populations.
