When to prune begonia 'midnight magic' 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 'midnight magic'
Cut dead petioles cleanly at the rhizome using sterilised scissors. To control spread, trim rhizome tips back by a few centimetres just before new growth flushes in spring. Avoid removing healthy foliage — the leaves are the ornamental feature.
Begonia rex-cultorum 'Midnight Magic' is a Rex begonia grown for its vividly patterned foliage. It needs very little pruning. Remove dead or damaged leaves at the petiole base. If the plant becomes crowded or a rhizome tip grows too far beyond the pot, trim that rhizome tip back to encourage denser, more compact 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.
