When to prune dieffenbachia sparkles 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 sparkles
Cut stems cleanly at a node with a sterile blade. Wear gloves when handling — Dieffenbachia sap is a potent irritant to skin, eyes, and mucous membranes.
Dieffenbachia 'Sparkles' needs periodic pruning to stay compact. Lower leaves drop naturally over time — remove them cleanly at the stem. If the plant grows tall and bare at the base, cut the main cane back to a node in spring; it will resprout vigorously. Always use gloves — sap is toxic.

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.
