Troubleshooting
Mintleaf Spurflower problems — and how to fix them
Mintleaf Spurflower (Plectranthus madagascariensis) 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
The most common cause of decline; the succulent stems collapse quickly when roots sit in waterlogged compost. Ensure the pot has drainage holes and never leave it standing in a saucer of water.
Whitefly
Whitefly nymphs cluster on the underside of the aromatic foliage and are particularly attracted to plants kept in warm, sheltered conditions. Treat with insecticidal soap or a yellow sticky trap and improve air circulation.
