When to prune syngonium 'white butterfly' 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 syngonium 'white butterfly'
Pinch or cut stems just above a leaf node using clean scissors. For a bushier habit, cut back up to one-third of the longest stems. Reversion removal: trace the all-green stem to its origin and cut it off entirely.
Syngonium White Butterfly benefits from regular pruning to maintain a bushy, compact shape — left unpruned it becomes a climbing vine. Pinch or cut back long trailing stems to encourage branching. Remove any fully green (reverted) stems promptly to preserve the variegation. Regular light pruning is the key to a full, attractive plant.

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.
