When to prune euphorbia pseudocactus in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune euphorbia pseudocactus
Sterilize a sharp blade, cut flush to the parent stem, and immediately rinse the wound with cold water to slow latex bleed. Allow the cut surface to callus in a dry, bright spot before any moisture reaches it.
Euphorbia pseudocactus is a branching, cactus-like succulent that needs minimal pruning. Removing dead or shriveled stems is all that is typically required. If a branch becomes unsightly or damaged, cut it cleanly at the base. Always protect skin and eyes from the caustic white latex sap, which is toxic on contact.

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.
