When to prune candelabra euphorbia 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 candelabra euphorbia
Using gloves and eye protection, cut a stem back to a lateral branch or the main trunk using a sharp clean blade. Allow the latex to stop flowing, then let the wound callous in a dry location for several days before watering.
Candelabra Euphorbia requires very little pruning indoors. Remove dead, damaged, or diseased stems as needed. If size control is necessary, trim a branch back to a junction point in spring — always wear gloves and eye protection because the latex sap is a severe skin and eye irritant. This plant grows slowly indoors.

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.
