When to prune string of hearts 'silver glory' 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.

Cut trailing stems just above a leaf node using clean scissors. Aim to remove no more than one-third of the vine length at once. Place cuttings (2–3 nodes) in water or moist soil to propagate.
String of Hearts 'Silver Glory' benefits from light pruning to keep its trailing vines tidy and bushy. Trim long, sparse stems back by one-third to encourage branching and denser growth. Remove any dead or shrivelled leaves. Pruned cuttings root easily in water or soil, making trimming doubly useful.

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.
