When to prune euphorbia ferox 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 ferox
Using thick puncture-resistant gloves and eye protection, cut dead stems flush at the base with sterilized pruners. Flush the wound with cold water to slow sap. Keep the plant dry and in bright light until the wound calluses.
Euphorbia ferox is a slow-growing, densely spiny succulent that needs no routine pruning. Remove individual stems only if they die or rot at the base. Extreme caution is essential: the spines can cause injury and the latex is toxic. Avoid unnecessary cuts — this species is valued for its untamed, clustered form.

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.
