Forest Elephant's Foot problems — and how to fix them
Forest Elephant's Foot (Dioscorea sylvatica) 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.
Caudex rot in summer
The most common failure: continuing to water during summer dormancy causes the caudex to soften and rot from the base. Withhold water when vines die back and resume only once new shoots emerge in autumn.
Failure to produce new vines in autumn
If the caudex was kept too warm and wet in summer, or too cold during dormancy, it may be slow to break dormancy. Ensure a dry, warm dormancy (18–25°C) and begin very light watering in early autumn to trigger growth.
Vine dieback from cold draughts
The annual vines are frost-tender and will collapse if exposed to temperatures below 10°C. Keep indoors year-round in temperate climates; the loss of vines mid-season stunts the caudex's annual energy reserve build-up.
