Troubleshooting
Stapelia hirsuta problems — and how to fix them
Stapelia hirsuta (Stapelia hirsuta) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Stem rot
Mushy, blackening stems from overwatering or cold-damp soil. Excise rotted tissue, let cuts callus, and re-root sound stem pieces in dry gritty mix.
Few or no flowers
Caused by insufficient light or a missed dry winter rest. Increase light and keep the plant nearly dry over winter to set buds the next season.
Mealybugs
White waxy clusters lodge in stem grooves and on roots. Dab with 70% isopropyl alcohol and examine the root ball when repotting to catch root mealybugs.
Carrion odour and flies
Open flowers smell strongly of rotting meat and may attract egg-laying flies. This is normal; site flowering plants away from living spaces if the scent is bothersome.
