When to prune begonia foliosa 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 foliosa
Use clean scissors or snips to remove dead stems at the base. For leggy growth, cut stems back to a healthy leaf node or by up to one-third. Avoid removing more than a third of the plant at once.
Begonia foliosa is a shrub-type begonia with fine, fernlike foliage that grows as a compact houseplant. It rarely needs heavy pruning. Remove any dead, damaged, or crossing stems as needed. If the plant becomes leggy, cut stems back by a third in spring to encourage bushier growth.

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.
