When to prune euphorbia symmetrica 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 symmetrica
Remove only dead or damaged surface tissue with a sterile scalpel or sharp knife, cutting just below the affected area. Blot latex immediately with a dry tissue and let the wound callous in a warm, dry location for several days.
Euphorbia symmetrica is a slow-growing, globose succulent with a neat spherical form. It needs virtually no pruning. Only remove dead outer tissue or damage caused by rot or pests using a clean, dry blade. Always wear gloves — the milky latex is toxic.

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.
