When to prune perplexing rebutia 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 perplexing rebutia
Separate offsets by twisting gently or cutting at the base. Let cut surfaces callous for a day before potting in free-draining cactus mix. For rot, excise to clean tissue and dust with sulphur.
Perplexing Rebutia (Rebutia perplexa) is a tiny, clustering cactus that naturally maintains a neat mounded form and needs no routine pruning. Remove individual offsets in spring if you wish to propagate or thin a crowded cluster. Deal with any rot promptly by cutting back to firm, healthy tissue with a sterilised blade.

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.
