How to prune gloriosa daisy

Deadhead throughout summer; final cutback or removal in autumn. Snip spent flower stems back to the nearest set of leaves or lateral bud. Allow a few late-season heads to set seed if you want self-seeding. Remove or cut back to the crown in autumn.

Deadheading prolongs flowering significantly — remove spent blooms regularly throughout summer. If growing as a biennial or short-lived perennial, allow a few late seed heads to mature for self-seeding. Cut back hard in autumn or remove plants entirely if treating as an annual.
