When to prune japanese cedar 'globosa nana' 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 japanese cedar 'globosa nana'
Remove any dead or winter-bronzed shoots by cutting back to a healthy lateral. If a strong upright shoot disrupts the globe shape, cut it at the base before it lignifies. Avoid routine shearing — the cultivar's form is self-regulating.
Cryptomeria japonica 'Globosa Nana' is a slow-growing, naturally globe-shaped dwarf that almost never needs pruning. Its tight, symmetrical habit is a genetic trait, not something that needs to be clipped into shape. Remove any dead shoots in spring and occasionally rub out vigorous upright shoots that break the globose outline.

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.
