How to prune antirrhinum majus 'chantilly bronze'

Pinch young plants early; deadhead throughout; cutback after first flush. Pinch growing tips when plants reach 10–15 cm to promote branching. Once flowering, cut spent stems back to a healthy lateral. Mid-season, trim all stems back by one-third and feed to prompt a second wave.

Deadhead every 1–2 weeks; one mid-season cutback. 'Chantilly Bronze' has an open, airy habit with loosely branched stems rather than the classic stiff spike. This makes deadheading easier — remove individual spent blooms along each stem. Pinching tips of young plants encourages extra branching. A mid-season trim after the first flush rewards you with continued flowering through summer.
