Troubleshooting
Konjac problems — and how to fix them
Konjac (Amorphophallus konjac) 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 in dormancy
Caused by moisture and cold while dormant. Keep the lifted or potted corm dry and above 10°C through winter.
Leaf scorch
Direct midday sun burns the single leaf. Site in dappled shade or bright indirect light.
Failure to emerge / weak leaf
An undersized or stressed corm produces a smaller leaf or none. Feed well in growth and store the corm properly to build size.
Foul smell when flowering
Normal: the spring inflorescence emits a carrion odour to attract pollinators. Move flowering plants outdoors or to a ventilated spot.
Prevent konjac problems before they start
Most konjac issues are care-mismatch, not bad luck. Dial in the basics:
