How to prune motherwort

Immediately after flowering to prevent self-seeding; full cutback in late autumn or early spring. Snip spent flower stalks at the base before seeds ripen. For the seasonal cutback, use loppers or shears to cut all stems to within 5–10 cm of the ground.

Deadhead after each bloom; hard cutback once a year. Motherwort is a vigorous self-seeder, so deadheading promptly after flowering is the most important pruning task. Cut flower stems back before seed sets to prevent unwanted spread. In late autumn or early spring, cut the whole clump down to the basal rosette. This keeps the plant tidy and manageable.
