When to prune euphorbia decaryi 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 decaryi
Use gloves and eye protection. Snip dead leaves at the base with clean scissors or snips, and remove spent inflorescences back to the nearest healthy node. Never cut into healthy main stems.
Euphorbia decaryi is a dwarf Madagascar succulent that needs almost no pruning. Remove dead or damaged leaves and spent flower stalks as they appear. Do not cut into the main stems — this triggers milky latex sap that irritates skin and eyes. Beyond that, leave the plant alone.

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.
