Late winter to early spring; deadhead in autumn if self-seeding is a concern. Cut the whole clump back to 10–15 cm above ground in early spring using garden shears. To limit self-seeding, cut seed heads before they mature and drop, or remove seedlings from around the parent plant throughout spring and summer.
