When to prune syngonium 'three kings' 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 'three kings'
Pinch or cut growing tips just above a node to promote branching. Remove reverted green stems at the base. Trim long vines back to the desired length, cutting just above a node.
Syngonium 'Three Kings' needs minimal pruning — mainly removing dead or yellowing leaves and trimming back vining stems when they become leggy. Pinching tips encourages a compact mound. Because its variegation is unstable, watch for all-green stems and remove them promptly to preserve the speckled pattern.

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.
