UK pruning guide · RHS timing
When to prune begonia subvillosa 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 subvillosa
Trim back any overly long or bare stems to a healthy leaf node using clean, sharp scissors. Remove dead flower stems at their base to keep the plant tidy.
Begonia subvillosa is a species begonia with a naturally shrubby, branching habit. It benefits from light annual pruning to remove weak or spent stems and to keep the plant from becoming leggy. Remove dead flower stalks promptly. It does not need heavy cutting back — light tidying after flowering is sufficient.

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.
