When to prune begonia manicata 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 manicata
Cut dead or yellowing leaves cleanly at the petiole. Remove spent flower stems by cutting at the rhizome base. Trim any overly long stems back to a node in spring if needed.
Begonia manicata is a robust rhizomatous begonia with large leaves. Pruning needs are minimal — remove dead or damaged leaves and spent flower stalks. In spring, you can trim back any stems that have grown too long to keep the plant tidy. The rhizome itself should not be cut unless you are propagating.

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.
