When to prune strawberry begonia in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune strawberry begonia
Cut spent flower stems at soil level once blooms finish. Trim stolons (runners) with scissors if they extend beyond the desired area. Remove individual dead leaves by pulling or cutting cleanly at the petiole.
Strawberry Begonia (not a true begonia) needs very little pruning. Remove spent flower stalks after the summer bloom flush and snip away any dead or damaged leaves at the base. The plant spreads via stolons — trim these back if the plant is outgrowing its space. No hard pruning required.

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.
