When to prune holger juniper in the UK
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 holger juniper
Remove dead stems to the base or back to a live lateral. Shorten overlong shoots by cutting just above a healthy side branch with foliage. Avoid shearing — the naturally layered, spreading habit is the ornamental feature.
Holger Juniper is a spreading, semi-prostrate shrub with creamy-yellow new growth. Prune lightly in early spring to remove any dead or frost-damaged stems and trim back leading shoots that are extending beyond the desired footprint. Cutting back to a foliage-bearing lateral keeps the plant tidy without exposing dead bare wood.

Is it illegal to prune holger juniper in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check holger juniper for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
