When to prune variegated string of pearls 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 pearls
Snip bare or reverted stems back to where healthy variegated pearls begin, using clean scissors. Lay cuttings on the soil surface in the same pot to fill gaps. Avoid burying the pearls.
Variegated String of Pearls rarely needs pruning, but trim bare stems where pearls have dropped to keep the plant tidy. Cut any all-green reverted stems promptly to maintain variegation. Overwatering causes pearl drop more often than poor pruning — address root health first. Trimmings root easily on moist 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.
