When to prune euphorbia ammak 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 ammak
Make a clean cut with a sterilized saw or loppers. Apply cold water to the cut to slow sap flow. Keep children and pets away from work area. Allow the cut to air-dry and callus fully before watering resumes.
Euphorbia ammak is a large, columnar succulent grown for its dramatic architectural form and needs virtually no pruning indoors. Only remove dead, diseased, or frost-damaged branches. Wear full protection — the milky latex is severely caustic. Never cut to control height; if it outgrows your space, pot size restriction is a gentler approach.

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.
