Troubleshooting
Orange Woolly Sage problems — and how to fix them
Orange Woolly Sage (Salvia confertiflora) 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.
Glasshouse red spider mite
When grown under glass in warm, dry conditions, two-spotted spider mite (Tetranychus urticae) colonises leaf undersides, causing yellow stippling; maintain higher humidity and treat with biological control (Phytoseiulus persimilis) or horticultural soap.
Powdery mildew and root rot
Poor air circulation under glass leads to powdery mildew; overwatering in winter causes Phytophthora root rot. Ensure good ventilation, reduce winter watering, and use free-draining compost.
