When to prune curio rowleyanus 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 curio rowleyanus
Use clean scissors to snip individual strands just above a leaf node or back to the soil line. Do not cut into healthy, bead-covered stems unless they have become bare or diseased.
String of pearls needs minimal pruning. Remove dead, shriveled, or diseased strands at any time to keep the plant tidy. If stems grow bare at the base, trim them back to encourage fresh growth from the crown. Pruning is purely cosmetic — the plant will not suffer if left unpruned.

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.
