Silver Spurflower problems — and how to fix them
Silver Spurflower (Plectranthus argentatus) 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.
Powdery mildew on hairy leaves
The dense leaf hairs can trap moisture and fungal spores in humid or crowded conditions. Improve air circulation, avoid overhead watering, and apply a sulphur-based or baking-soda fungicide at first sign.
Leggy, floppy growth
In shade or after a long growing season the stems elongate and flop; pinch the tips regularly to encourage bushiness, and cut hard back in early spring to rejuvenate old plants.
