How to prune dahlia 'breakout'

Pinch in late spring; deadhead through summer and autumn. Pinch the growing tip above the second or third leaf pair after planting. Deadhead by cutting spent flowers back to the nearest lateral bud. For wildlife benefit, leave a proportion of flowers to go over naturally, as pollinators value the accessible single blooms.

Pinch once; deadhead every 7–10 days. Dahlia 'Breakout' is a collarette dahlia that flowers freely and benefits from pinching early in the season for a bushier habit. Deadhead spent blooms to extend flowering from midsummer into autumn. Its open single-plus-collar form is attractive to pollinators, so consider leaving some blooms to mature for wildlife benefit.
