When to prune begonia 'cleopatra' in the UK

How to prune begonia 'cleopatra'
Cut dead leaves at the petiole base. Remove spent flower stalks flush with the rhizome. If the rhizome crawls over the pot edge, trim it back or repot and divide.
Begonia 'Cleopatra' is a popular rhizomatous begonia with distinctive star-shaped, hairy leaves. It needs very little pruning — remove dead or yellowing leaves at the petiole base and cut back spent flower stems after blooming. The creeping rhizome should not be pruned unless it outgrows its pot and you wish to divide it.

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.
