When to prune begonia 'torch' 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 'torch'
Cut bare or exhausted canes to 15–20 cm from the base in spring. Pinch growing tips 2–3 cm above a node throughout the active season to stimulate lateral branching and additional flower clusters.
Begonia 'Torch' is a cane-type begonia with pendulous coral-orange flower clusters. Like other cane begonias it can grow tall and leggy without pruning. Pinch stem tips to promote branching and more flower nodes. Cut old bare canes back to 15–20 cm in early spring. Remove spent flower stalks regularly.

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.
