When to prune oakleaf 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 oakleaf croton
Wearing gloves, use sharp, clean pruners to cut leggy stems back to just above a leaf node. Aim for an even, balanced shape. Remove dead stems at the base. Clean sap from blades promptly. New side shoots will emerge from below each cut.
Oakleaf Croton can become leggy without pruning, so annual shaping in spring keeps it full and attractive. Cut back overgrown stems by up to one-third to encourage branching and denser foliage. Wear gloves at all times — croton sap is a skin irritant and toxic. Remove any dead or damaged stems at their base.

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.
