When to prune begonia nelumbiifolia in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune begonia nelumbiifolia
Snap or cut dead leaves cleanly at the petiole base. Trim rhizome tips with a clean blade if they outgrow the container or lose leaves, leaving at least a few healthy growing points.
Begonia nelumbiifolia is a large-leafed rhizomatous begonia grown primarily for its dramatic foliage. It needs very little pruning. Remove dead or yellowing leaves at their base as they appear. If the rhizome spreads beyond its pot or produces bare, leafless stems, trim the rhizome tips in spring.

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.
