Troubleshooting
Elephant Foot Yam problems — and how to fix them
Elephant Foot Yam (Amorphophallus paeoniifolius) 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 in storage
The leading cause of loss. Store the dormant corm in dry, barely moist sand or vermiculite at 15-18°C from when the leaf dies back until spring. Never store in wet medium.
Failure to emerge in spring
Usually caused by cold, wet storage or a corm that lost too much energy. Ensure warm storage (above 15°C) and begin gentle warming in late winter to stimulate dormancy break.
Leaf yellowing
Towards autumn, natural senescence. At other times, check for overwatering or root damage.
Pests (vine weevil)
Large larvae can damage or hollow out the corm. Use vine-weevil biological control (nematodes) when repotting in spring.
Odour from inflorescence
The spathe-and-spadix inflorescence produces a strong carrion smell for 1-2 days to attract pollinators. Normal and temporary; move outdoors during flowering if the smell is unwanted.
