Troubleshooting
Forest Spurflower problems — and how to fix them
Forest Spurflower (Plectranthus fruticosus) 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.
Leggy, sparse growth
Without annual pruning, the shrub becomes woody and bare at the base. Cut back by one-third in late winter before new growth emerges to maintain a compact, bushy shape and maximise flowering.
Aphids
Soft new growth and flower spikes are targeted by aphids, particularly under glass. Check growing tips regularly and treat infestations promptly with a strong water jet followed by insecticidal soap or neem oil.
