How to prune monarda 'jacob cline'

Chelsea chop in late May to early June; deadhead through summer; hard cutback in autumn or early spring. Deadhead by cutting spent flower whorls back to a new bud or lateral shoot — this often triggers a second flush. For the Chelsea chop, cut all stems back by one-third to one-half in late May. Cut the entire clump to ground level in autumn after flowering ends or in early spring before new growth appears.

Deadhead regularly through summer; Chelsea chop once in late spring; hard cutback once annually. Monarda 'Jacob Cline' benefits from deadheading to prolong flowering and a Chelsea chop in late spring to reduce height and improve air circulation (it is less powdery-mildew prone than older cultivars but still benefits). Cut back hard to the ground in autumn or early spring after the stems have provided winter habitat.
