When to prune begonia 'potpourri' 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 'potpourri'
Pinch or snip stems just above a leaf node using clean, sharp scissors. Remove no more than one-third of the plant at a time to avoid stress.
Begonia 'Potpourri' benefits from light pruning to stay compact and floriferous. Pinch back leggy stems just above a leaf node to encourage bushy growth and more blooms. Remove spent flowers and any dead or damaged stems promptly. Beyond that, this houseplant begonia needs minimal intervention — over-pruning weakens it.

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.
