Amorphophallus muelleri problems — and how to fix them
Amorphophallus muelleri (Amorphophallus muelleri) 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.
Calcium oxalate irritation
Handling cut tubers can itch and irritate skin; the raw corm is inedible until processed. Wear gloves and never feed raw plant material to pets or people.
Tuber rot from overwatering
Waterlogged or cold soil in dormancy rots the corm. Keep dormant tubers dry and ensure free drainage during growth.
Premature dormancy in cool conditions
Temperatures below about 18°C can trigger early leaf die-back and stall tuber bulking. Maintain warm, humid growing conditions through the season.
Leaf scorch in full sun
The single understorey-adapted leaf browns under direct tropical sun. Provide 50-60% shade or bright filtered light.
