How to prune rose campion

Deadhead throughout flowering (early to midsummer); remove spent stems after flowering; remove exhausted rosettes in autumn. Snip off spent flower stems back to the basal silver-leaved rosette. After flowering, cut all stalks to ground level. Pull out or compost old rosettes that have set seed and died back. Allow some seed heads to ripen if self-seeding is welcome.

Deadhead regularly during flowering; cut back once after flowering; remove spent rosettes as needed. Rose campion is a short-lived perennial or biennial that self-seeds prolifically. Deadhead spent flowers if you want to limit spreading, or leave them to naturalise. Cut back flowered stems to basal foliage after bloom. Remove old rosettes that have finished their life cycle. The silvery foliage rosettes need no pruning.
