When to prune begonia 'benitochiba' in the UK
Why the timing differs here
This one bleeds sap heavily if cut in late winter or early spring, so the RHS advises pruning in late summer or early autumn instead — the opposite of the general dormant-season rule most pruning guides give.
How to prune begonia 'benitochiba'
Snap or snip dead leaves cleanly at the petiole base. Remove flower stalks promptly to maintain foliage vigor. If stems become bare and leggy, cut back to a healthy node or to the rhizome level in spring.
Rex begonias like 'Benitochiba' are grown for their ornate foliage, not flowers. They need very little pruning. Remove dead or yellowing leaves and any spent flower stems (flowers are insignificant and best removed to keep energy in the leaves). Trim leggy stems back to a node in spring if needed.

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.
