When to prune prickly pear 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 prickly pear cactus
Use long-handled loppers or shears sterilised with isopropyl alcohol. Sever pads cleanly at the joint between two pads — never mid-pad. Handle removed sections with tongs and place in a dry spot to callous before disposal or replanting as cuttings.
Prickly Pear Cactus benefits from occasional pruning to control size, remove diseased pads, and harvest cladodes. Cut whole pads at the joint with long-handled shears in spring. Wear puncture-resistant gloves and eye protection at all times. Remove any pads showing soft rot immediately regardless of season.

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.
