How to prune chinese yam

Cut back dead vines to the ground each autumn; trim wayward stems during summer as needed. In autumn, once vines die back after frost, cut all stems to ground level with clean shears and compost the top growth. During summer, shorten stems that have outgrown their support by cutting just above a leaf node. Harvest the deep tubers by digging carefully in autumn or early spring.

Full cutback once annually in autumn; light trimming as needed in summer. Chinese Yam is a vigorous perennial climber grown for its edible tubers and aerial bulbils. Pruning is minimal but useful — cut vines back hard to the base each autumn once the foliage dies down after frost. During the growing season, trim excessively long or tangled stems to keep the plant within its support structure.
