UK pruning guide · RHS timing
When to prune chain cactus in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune chain cactus
Use clean scissors or snips to cut stems at a natural joint or segment boundary. Remove dead or shriveled segments entirely. To encourage a fuller look, trim stem tips back by one to two segments, which may promote branching.
Chain Cactus (Rhipsalis paradoxa) is a trailing epiphytic cactus that needs minimal pruning. No shaping is required. Trim back any overly long, dead, or damaged stems to maintain a tidy appearance or to keep the plant in bounds for its pot or hanging basket. Light trimming can be done any time.

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.
