When to prune begonia schmidtiana 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 schmidtiana
Pinch or snip spent flower stems at their origin. Pinch stem tips above a node to promote compact branching. In spring, cut the whole plant back by up to one-third to refresh it and promote new flowering shoots.
Begonia schmidtiana is a fibrous-rooted, compact begonia that produces small pink-white flowers nearly year-round. It stays relatively tidy but benefits from light pruning to remove spent flowers and any straggly stems. Pinch stem tips to encourage bushing. Cut back by one-third in early spring if growth becomes lax.

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.
