How to prune monarda 'marshall's delight'

Chelsea chop in late May; deadhead through summer; hard cutback in autumn or early spring. Deadhead spent flower whorls to a lateral bud or shoot to encourage rebloom. Apply the Chelsea chop (cut by one-third to one-half) in late May to produce more compact plants with later, extended flowering. Cut to ground level after flowering or before spring growth begins.

Deadhead regularly; Chelsea chop once in late spring; hard cutback once annually. Monarda 'Marshall's Delight' is a powdery-mildew-resistant cultivar that benefits from deadheading for extended bloom and a Chelsea chop in late spring to reduce sprawl. Cut back to the ground after flowering in autumn or in early spring. Good airflow from spacing reduces disease pressure further.
