When to prune begonia odorata 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 odorata
Deadhead by cutting spent flower stems back to a leaf node. Reduce leggy canes by up to one-third, cutting cleanly above a node with clean snips.
Begonia odorata is a naturally upright, cane-type species with fragrant flowers. Prune lightly after flowering to remove spent blooms and trim any leggy stems back to a node. A light spring cut of up to one-third keeps the plant compact. Remove dead or yellowing leaves as they appear.

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.
