When to prune begonia peltata 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 begonia peltata
Snap or cut dead leaves cleanly at the stem. Trim elongated stems back to a healthy node with sharp, clean scissors. Avoid over-pruning — this species stores water in its stems and leaves.
Begonia peltata is a thick-leaved succulent-type begonia that needs minimal pruning. It rarely becomes leggy under good light. Prune only to remove dead, yellowing, or damaged leaves and stems at the base. If stems elongate in low light, cut back by one-third in spring to encourage compact regrowth.

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.
