When to prune steinmann's 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 steinmann's rebutia
Detach pups by hand or with a sterile blade at their attachment point. Allow cut surfaces to dry for 24–48 hours before placing in dry cactus mix. Avoid cutting into the main stem.
Steinmann's Rebutia (Rebutia steinmannii) is a compact clustering cactus requiring no routine pruning. Offsets freely around the parent body over time. Remove pups in spring if propagating or to prevent overcrowding in the pot. Otherwise, leave the colony undisturbed — it produces flowers most freely when slightly crowded.

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.
