When to prune schlumbergera × buckleyi 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 schlumbergera × buckleyi
Twist or pinch off 1–2 stem segments at a joint to shape the plant or stimulate branching. No hard cutting is needed or recommended.
Schlumbergera × buckleyi (Christmas cactus) rarely needs pruning beyond removing a few stem segments to shape the plant or propagate cuttings. Pruning is not required for flowering — flower bud set is triggered by short days and cool nights. Pinching off 1–2 stem segments in late spring can encourage branching and a fuller plant.

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.
