When to prune begonia aconitifolia 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 begonia aconitifolia

Begonia aconitifolia is an angel-wing cane begonia that can grow tall and benefits from pruning to keep it manageable. Cut main canes back by one-third in early spring to encourage bushy new growth and more flowers. Remove any dead or damaged canes at the base. Pinching young stems promotes branching.

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.
