When to prune golden lace 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 golden lace cactus
Wear gloves. Use a sterile blade to cut or twist away dead/rotted offsets at the base. For propagation, remove a healthy pup, dust the cut end with sulfur or charcoal, and leave it to callous for 2–3 days before potting in dry cactus mix.
Golden Lace Cactus (Mammillaria elongata 'Copper King') naturally forms dense, attractive clusters and needs no routine pruning. Do not shape or shorten individual stems — the cactus will scar permanently. Only remove fully dead or rotting offsets. Detaching healthy pups for propagation is the main reason to cut.

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.
