When to prune pellionia daveauana 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 pellionia daveauana
Pinch stem tips back to a healthy leaf node to promote branching. Cut back overly long trailing stems by up to one-third with clean scissors.
Pellionia (watermelon begonia) benefits from occasional trimming to keep its trailing stems tidy and encourage denser growth. It does not need heavy pruning. Pinch or trim leggy stems back to a node in spring or summer. Remove any yellowed or damaged leaves as they appear throughout the year.

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.
