Pruning black-eyed susan — FAQ
When should I prune black-eyed susan?
Deadhead throughout summer; cut back in late autumn or early spring. Snip spent blooms just above a leaf node to encourage a second flush. In autumn or early spring, cut all stems back to 3–4 inches above ground using sharp secateurs.
How often does black-eyed susan need pruning?
Deadhead weekly in summer; full cutback once annually. Black-Eyed Susan benefits from deadheading to extend blooming through summer, and a hard cutback in late autumn or early spring. Leave some seedheads standing over winter to feed birds and allow self-seeding. Cut the whole plant to a few inches above ground once frost has blackened the foliage.
