When to prune selenicereus anthonyanus 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 selenicereus anthonyanus
Snip individual stems back to a convenient joint using clean scissors. Allow cut ends to callus for 24 hours before placing in propagation mix if rooting. Remove dead segments by cutting cleanly at a joint.
Fishbone cactus (Selenicereus anthonyanus) rarely needs heavy pruning. Trim stray or excessively long stems in spring to keep the plant tidy and encourage branching. Remove any dead or shrivelled sections at any time. Pruned segments propagate easily in slightly moist potting mix, making trimming productive rather than wasteful.

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.
