When to prune begonia 'escargot' cocktail series 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 'escargot' cocktail series
Pinch growing tips just above a leaf node to promote branching. If the plant becomes straggly, cut back by up to one-half above a healthy node. Remove dead leaves at the petiole. Deadheading is unnecessary.
Begonia 'Cocktail Vodka' (Semperflorens type) is largely self-cleaning and needs minimal pruning. Pinch stem tips in early spring to encourage bushiness, and cut back any leggy growth by one-half mid-season. Spent flowers drop on their own. Remove dead or damaged leaves as they appear to keep the plant tidy.

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.
