When to prune golden torch 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 torch cactus
Use a sharp, sterilised knife to cut cleanly through the stem just above healthy tissue. Dust the wound with powdered sulfur or activated charcoal, then leave it to callous for several days before replanting or watering.
Golden Torch Cactus grows as a tall columnar stem and needs no routine pruning. Remove only dead, diseased, or frost-damaged sections with a clean, sharp knife. If a stem is etiolated (stretched from low light), remove it at soil level and propagate as a cutting rather than trying to shorten it.

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.
