When to prune zanzibar 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 zanzibar croton
Cut leggy stems back to just above a leaf node or dormant bud with clean, sharp pruners. Pinch out the growing tip of young shoots to encourage a more branched habit. Wear gloves and wipe the sap off blades immediately after use.
Zanzibar Croton, with its narrow strap-like leaves, benefits from occasional pruning to prevent legginess. Prune in spring by cutting bare or overly long stems back to a node, which prompts branching. Wear gloves throughout — the white latex sap irritates skin and is toxic. Young plants respond especially well to tip-pinching.

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.
