UK pruning guide · RHS timing
When to prune begonia solananthera 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 solananthera
Cut trailing stems back by up to one-third to a node after flowering. Remove spent flower stems at their base. Deadleaf routinely to prevent fungal issues in the dense foliage.
Begonia solananthera is a trailing, scandent species with white fragrant flowers, often grown in hanging baskets. Prune after flowering ends to remove spent stems and encourage a second flush. Trim back trailing stems by about one-third to keep growth manageable. Remove dead leaves and stems as needed throughout the year.

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.
