When to prune variegated string of hearts 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 variegated string of hearts
Cut bare or reverted stems back to a healthy variegated node using sharp scissors. Pin trimmed sections back into the pot soil to fill gaps, or propagate separately in water.
Variegated String of Hearts needs light pruning to stay full and healthy. Long bare stems are common — trim them back to encourage bushy, dense growth. Pinch off any stems that have reverted to all-green to preserve variegation. Propagate the trimmings easily in water or soil.

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.
