When to prune turtle vine 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 turtle vine
Pinch stem tips just above a leaf node using your fingers or clean scissors. Cut leggy stems back by one-third to one-half; the cut ends can be propagated easily in water or soil.
Turtle Vine benefits from regular pruning to prevent legginess and encourage dense, bushy growth. Pinch or trim long trailing stems back by a third to a half to keep the plant compact. Without pruning it becomes straggly, with bare lower stems. It's fast-growing, so light trimming every few months keeps it 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.
