When to prune rhizomatous begonia 'cleopatra' in the UK
Why the timing differs here

How to prune rhizomatous begonia 'cleopatra'
Use clean scissors to remove dead or damaged leaves at their junction with the rhizome. Snip spent flower stalks cleanly at the base. If a rhizome grows over the pot edge and looks straggly, trim it back to a healthy growth point in spring.
Begonia 'Cleopatra' is a rhizomatous houseplant that needs minimal pruning. Remove dead or damaged leaves at their base as they appear. After flowering, snip spent flower stalks down to the rhizome. You can trim leggy rhizomes back to keep the plant compact, but it rarely needs heavy cutting.

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.
