Why the timing differs here

RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.

How to prune chinese juniper 'itoigawa'

Pinch or snip extending shoot tips back by one-third to one-half, always leaving green foliage on every shoot retained. Use fingers or scissors — do not shear flat, as browning cut-foliage looks unnatural. Remove any dead or browning inner foliage periodically.

Chinese Juniper 'Itoigawa' is one of the premier bonsai subjects, prized for fine foliage and compact growth. Regular pinching through the growing season maintains dense, cloud-like pads. Never cut back to bare wood — junipers do not back-bud on leafless branches. Remove dead interior foliage in autumn to reduce disease risk.

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.
