How to prune feverfew

Deadhead throughout summer as flowers fade; cut back after main flowering period in late summer. Snip off spent flower heads just above a set of leaves. After the main flush, cut the whole plant back by one-half to two-thirds to stimulate a fresh rosette of foliage. Remove any weak or dead stems entirely.

Deadhead regularly in summer; cut back once or twice per season. Feverfew is a short-lived perennial or biennial that self-seeds freely. Deadhead spent flowers promptly to control spreading and to extend the blooming period. After flowering, cut plants back by half to encourage fresh basal growth. If you want it to naturalize, leave a few heads to set seed.
