When to prune cercidiphyllum japonicum 'pendulum' in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune cercidiphyllum japonicum 'pendulum'
Use sharp secateurs to remove dead stems at their base. Trim any stems growing along the ground back to a point where they still arch gracefully. Avoid cutting into the main cascading branches — the pendulous silhouette is what makes this cultivar distinctive.
Cercidiphyllum japonicum 'Pendulum' is a weeping form that needs almost no pruning. Its cascading habit is its main ornamental feature and should be preserved. Remove only dead, diseased, or rubbing branches. Occasionally, stems touching the ground can be trimmed to keep growth tidy. Do not attempt to reshape the natural weeping structure.

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.
