How to prune laceleaf japanese maple 'crimson queen'
Use clean, sharp pruners or loppers to cut dead or crossing branches back to their origin. For light shaping, follow the natural weeping branch line rather than heading back indiscriminately. Avoid large cuts — wounds heal slowly on Japanese maples.
Crimson Queen is a slow-growing, weeping dissectum that develops a graceful natural form — heavy pruning destroys its character. Prune only to remove dead, damaged, or crossing branches. Light shaping to maintain the weeping silhouette is fine. Less is always more with this cultivar.

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.
