When to prune sandy sulcorebutia 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 sandy sulcorebutia
Use a clean, sharp blade to remove rotted or dead stems flush with the cluster. Let wounds callous before the plant is watered. Healthy offsets can be gently twisted free and potted after a day of callousing.
Sandy Sulcorebutia is a tiny clustering cactus that needs no pruning. It forms tight mounds of small globular stems. Remove individual stems only if they rot or die, separating them carefully from the clump. Detaching healthy offsets for propagation is optional, not maintenance.

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.
