When to prune begonia stipulacea 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 stipulacea
Pinch growing tips just above a node to promote branching. Cut bare or woody canes back to 15–20 cm from the base with clean secateurs. Use healthy cuttings to propagate new plants in water or moist compost.
Begonia stipulacea is a cane-type begonia with bamboo-like stems that can grow tall and leggy. Prune to encourage branching and control height. Pinch stem tips on young plants. Cut older, bare canes back to 15–20 cm in early spring. The plant responds well and breaks vigorously from old wood.

Pruning begonia stipulacea in the UK — FAQ
When should I prune begonia stipulacea in the UK?
Prune begonia stipulacea in early to mid spring. 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.

Is it illegal to prune begonia stipulacea in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check begonia stipulacea for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
