When to prune palm leaf begonia 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 palm leaf begonia
Cut canes back to just above a node or leaf joint using clean pruning shears. For very tall plants, stagger cuts across multiple stems rather than cutting all at once to avoid stressing the plant.
Palm Leaf Begonia (Begonia luxurians) is a tall cane-type begonia that benefits from pruning to control height and encourage branching. Cut leggy canes back by one-third in early spring to promote bushier, more compact growth. Deadhead spent flower clusters throughout the season. Without pruning it can become ungainly.

Pruning palm leaf begonia in the UK — FAQ
When should I prune palm leaf begonia in the UK?

Is it illegal to prune palm leaf begonia 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 palm leaf begonia 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.
