When to prune dieffenbachia amy 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 dieffenbachia amy
Cut main canes just above a node using a sharp, sterile blade. Remove cut material from pets and children's reach immediately; dispose of gloves or wash hands thoroughly.
Dieffenbachia 'Amy' is low-maintenance but benefits from occasional pruning to manage height and bushy appearance. Remove yellowing lower leaves as they occur. Leggy plants can be cut back hard to a node in spring and will resprout from the cane. Wear gloves every time — the sap is toxic and irritating.

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.
