When to prune snapdragon 'madame butterfly' 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 snapdragon 'madame butterfly'
Pinch the main stem tip once when the plant has 3–4 leaf pairs to promote branching. Remove spent spikes by cutting to the nearest healthy lateral shoot or strong leaf node.
Snapdragon 'Madame Butterfly' is a double azalea-flowered type that branches naturally and needs minimal pruning beyond deadheading. Pinching young plants once encourages even bushier growth. Cut spent flower spikes back to a lateral shoot regularly. This cultivar reblooms particularly well with consistent deadheading through summer and into autumn.

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.
