Pruning skullcap — FAQ
When should I prune skullcap?
Early summer for pinching; late autumn for seasonal cutback. Pinch or snip the top 5–8 cm of stems to encourage branching. Remove spent flower spikes by cutting to the nearest healthy leaf. In autumn, cut all stems to ground level or leave them until early spring.
How often does skullcap need pruning?
Pinching once in early summer; cutback once annually. Skullcap is a low-maintenance perennial herb that needs minimal pruning. Pinching stem tips in early summer encourages a bushier, more compact habit. Deadhead spent flowers to extend bloom. Cut the plant back to the basal growth in late autumn after stems die back, or leave stems for winter wildlife habitat.
