Pruning chinese artichoke — FAQ
When should I prune chinese artichoke?
Cut back dead top-growth in autumn after the first frosts kill the foliage. Cut yellowed stems to soil level with clean shears once frost has fully killed the top growth. If leaving tubers in the ground to overwinter, mulch the bed after cutting back. Harvest tubers progressively through winter as needed.
How often does chinese artichoke need pruning?
Once annually in autumn. Chinese Artichoke (Stachys affinis) is grown for its small, segmented tubers. Top growth dies back naturally after frost. No active pruning is needed during the growing season. In autumn, once the foliage yellows and dies back, cut stems to ground level. The tubers are then harvested or left in the ground for spring regrowth.
