When to prune mammy croton 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 mammy croton
Cut leggy or bare stems back to just above a healthy leaf node using sharp, clean pruners. On young plants, pinch out soft stem tips between your fingers to encourage bushiness. Wipe sap off blades after cutting to prevent skin irritation.
Mammy Croton benefits from pruning to keep its naturally compact, curly-leaved form dense and bushy. Prune in spring, removing up to one-third of any leggy stems. Always wear gloves — like all crotons, the milky white sap irritates skin and is toxic. Pinching out new growing tips promotes side branching on young plants.

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.
