Amorphophallus maximus problems — and how to fix them
Amorphophallus maximus (Amorphophallus maximus) 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 or airless compost, especially in 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. Move to bright filtered light or light shade.
Leaflet browning
Very dry air browns the leaflets. Raise humidity in growth and keep the plant away from heat sources.
Failure to re-sprout
A cold or soggy dormant rest can abort the next shoot. Keep the resting corm around 20°C and only just moist until growth resumes.
