When to prune baseball plant 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 baseball plant
If rot removal is necessary, cut away affected tissue with a sterilised blade, wearing gloves to avoid latex sap contact. Allow the wound to callous in a dry, bright spot before resuming watering.
Baseball Plant (Euphorbia obesa) requires no pruning whatsoever. It is a naturally globular, solitary succulent that does not branch or elongate in normal conditions. Simply remove any dead or shrivelled tissue if rot occurs. Pruning this plant is unnecessary and any cuts expose it to the same toxic latex risk as other euphorbias.

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.
