How to prune coreopsis 'zagreb'

Deadhead continuously through summer; cut back by half mid-season when flowering slows; cut to ground in autumn or spring. Deadhead regularly by snipping spent flower heads just above a leaf or bud. When overall flowering declines mid-season, shear the entire plant back by one-half with clean shears — this usually restores a full second flush of golden-yellow blooms within a few weeks.
