When to prune begonia carolineifolia in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune begonia carolineifolia
Cut dead or yellowing leaves cleanly at the base of the petiole with clean scissors. In spring, trim rhizome sections that creep over the pot edge. Do not remove large healthy leaves as the plant is a slow grower.
Begonia carolineifolia is a rhizomatous palm-leaf begonia with large compound leaves. It needs very little pruning. Remove dead or damaged leaves at the petiole base as they appear. Trim the creeping rhizome back to the pot edge in spring if it outgrows its container. Avoid cutting healthy leaves — the bold foliage is this plant's main feature.

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.
