When to prune espostoa melanostele 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 espostoa melanostele
Excise decayed tissue with a sterilised blade to clean, firm flesh. Treat the wound with sulphur powder and keep the plant in a warm, dry position until it fully calluses.
Espostoa melanostele is a slow-growing Peruvian columnar cactus cloaked in white woolly hair. It requires no pruning. Never cut the column or the pseudocephalium that develops along one side. The only warranted action is removing rotten basal tissue with a sterile blade if decay is detected.

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.
