When to prune antirrhinum majus 'chantilly bronze' in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune antirrhinum majus 'chantilly bronze'
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.
'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.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
