Troubleshooting
Amorphophallus prainii problems — and how to fix them
Amorphophallus prainii (Amorphophallus prainii) 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.
Corm rot
Cold, wet compost, especially during dormancy, rots the corm. Use a gritty free-draining mix and store the dormant corm warm and dryish.
Leaf scorch
Hot direct sun bleaches and crisps the single leaf. Provide bright filtered light or light shade.
Leaflet browning
Very dry air browns the fine leaflets. Raise humidity and keep away from heat sources during active growth.
Delayed dormancy break
A cool or damp rest delays the new shoot. Keep the dormant corm at around 20°C and only barely moist until growth restarts.
