When to prune cassytha rhipsalis 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 cassytha rhipsalis
Snip stems back to a node with clean, sharp scissors. Cuts stimulate branching just below the cut point. Removed stems can be propagated by laying on barely moist cactus compost in a warm, bright spot.
Rhipsalis cassytha (the most common mistletoe cactus) needs very little pruning. Trim overly long or damaged stems back to a node in spring using clean scissors. The plant is naturally pendulous and looks best left to trail freely. Pruning can encourage bushier branching, but it is entirely optional.

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.
