Amorphophallus hewittii problems — and how to fix them
Amorphophallus hewittii (Amorphophallus hewittii) 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.
Tuber rot
Wet, cold or poorly drained soil — especially during dormancy — rots the corm. Use a very free-draining mix and keep the dormant tuber dry.
Humidity and warmth sensitivity
As a Bornean rainforest species it sulks in cool, dry air, browning leaf margins and going dormant early. Maintain warm, humid, stable conditions in a greenhouse or indoors.
Leaf scorch
Direct sun burns the single understorey-adapted leaf. Provide bright filtered light or dappled shade.
Long unpredictable dormancy
The corm may stay dormant for many months. Keep it warm and barely moist and resist overwatering the bare pot, which causes rot rather than faster regrowth.
