When to prune begonia 'jurassic silver swirl' 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.

Snip flower stalks cleanly at the base with sterile scissors. Cut dead or tatty leaves at the petiole junction. Trim rhizome tips back to the pot edge only when necessary to prevent the plant from outgrowing its container.
Begonia 'Jurassic Silver Swirl' is a rex-type grown for its bold silvery foliage and rarely needs pruning. Remove flower stems at the base as they appear to redirect energy to leaves.

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.
