When to prune purple prickly pear 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 purple prickly pear
Wearing thick gloves, sever individual pads at the natural joint between segments using sharp, sterilised loppers or a knife. Allow cut surfaces to callous in a dry spot for several days before any repotting.
Purple Prickly Pear (Opuntia macrocentra) can be lightly pruned to control size or remove damaged pads. Always wear thick leather gloves — glochids (tiny barbed spines) are hazardous. Snap or cut entire pads at the joint between segments. Prune in late spring when the plant is actively growing and wounds callous quickly.

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.
