Pruning jerusalem artichoke — FAQ
When should I prune jerusalem artichoke?
Pinch/cut back in early summer; cut to ground after first hard frost. In early summer, cut the top third of stems to promote sturdier growth. Post-frost, cut all stems to 2–3 inches above soil. Remove any shoots emerging outside your desired clump at any time.
How often does jerusalem artichoke need pruning?
Once in early summer for height control; once post-frost for cleanup. Jerusalem Artichoke grows vigorously and can reach 8–10 feet. Cutting stems back by one-third in early summer reduces flopping and can improve tuber yield. After frost blackens the foliage, cut stems down to ground level. Manage spread by removing unwanted shoots — this plant spreads aggressively via tubers.
