Pruning st. john's wort — FAQ
When should I prune st. john's wort?
Early spring before new growth emerges; deadhead after first flush of flowers in midsummer. In early spring, cut all stems back to within a few inches of the ground using shears. After the main flowering period, shear plants back by one-third to encourage a second flush of blooms later in the season.
How often does st. john's wort need pruning?
Annually in spring; optional deadheading in summer. St. John's Wort (Hypericum perforatum) is a spreading perennial herb. Cut stems back hard in early spring to promote fresh, vigorous growth and better flowering. Deadheading after bloom is optional but can encourage a second flush. Without annual cutting back, plants become straggly and less productive over time.
