When to prune red mistletoe 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 mistletoe cactus
Use clean scissors to snip stems at a segment joint or at the base of a dead section. Avoid cutting mid-segment where possible, as clean joints callous more readily. A light trim of overly long stems can encourage branching.
Red Mistletoe Cactus (Rhipsalis pilocarpa) is an epiphytic, trailing cactus that requires very little pruning. Remove dead, shriveled, or damaged stems as they appear. If the plant grows too long for its hanging basket or pot, trim back individual stems at a segment joint. No shaping or regular schedule is needed.

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.
