When to prune rebutia krainziana 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 rebutia krainziana
Twist or cut dead or rotting offsets from the cluster at their base using a sterilised blade. Allow the wound to callous briefly in a dry, bright spot before resuming normal watering.
Rebutia krainziana is a compact, freely-clustering cactus that blooms prolifically from its offsets without any pruning. No cutting is needed or beneficial. Simply remove dead, shrivelled, or rotting offsets if they appear, using a clean blade. Healthy clumps flower more abundantly when left undisturbed.

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.
