When to prune peanut 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 peanut cactus
Gently twist or cut individual pup segments at the joint with a clean blade to propagate. Remove any visibly dead or shrivelled sections at their natural joints.
Peanut cactus (Echinopsis chamaecereus) does not need pruning. Its cheerful, finger-like stems spread naturally and the plant clusters freely. You may detach offsets by hand or with a clean tool for propagation, but no cutting of the main plant is needed. Simply remove any dead or shrivelled stems.

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.
