How to grow jerusalem artichoke
Helianthus tuberosus
When to plant jerusalem artichoke
NC State Extension says Jerusalem artichoke tubers may be planted in early spring, much like potatoes: plant whole tubers or pieces with two to three strong buds, and do not let the pieces dry out before planting. Tubers are harvested in fall about two weeks after the flowers fade.
Jerusalem Artichoke is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
