When to prune lady finger 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 lady finger cactus
Twist or cut offsets away from the base with a sterilised knife. For damaged fingers, cut cleanly at the joint. Allow all cut surfaces to callous for 24–48 hours. Use firm gloves — the hooked spines catch easily in fabric and skin.
Lady Finger Cactus needs very little pruning. Remove shrivelled, rotted, or damaged fingers cleanly at the base. Offsets (pups) can be detached in spring if you want to limit the cluster's spread or propagate. The cylindrical fingers are ornamental — no routine cutting is required or beneficial.

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.
