Helianthus tuberosus, commonly known as Jerusalem artichoke, is typically ready for harvest in late fall, after the first frost has killed the foliage. To harvest, carefully dig around the base of the plant to avoid damaging the tubers. Tubers can be harvested as needed throughout the winter, as they store well in the ground. Ensure to handle the tubers gently to prevent bruising, and store them in a cool, dark place if not used immediately.
