When to prune red orchid 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 red orchid cactus
Use clean scissors or a blade to cut spent flower stems and any dead tissue back to a healthy joint. Allow cut surfaces to dry briefly before watering.
Red orchid cactus needs very little pruning. Once flowers fade, remove spent blooms at their base. Trim any dead, rotting, or damaged stems back to healthy tissue. You can shorten overly long stems after flowering to keep the plant compact, but avoid heavy cutting as flower buds form on mature stems.

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.
