When to prune parsons 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 parsons juniper
Use loppers or pruners to remove dead stems at ground level. Thin interior congestion by cutting selected branches back to a foliage-bearing lateral. Avoid shearing, which creates a dense crust of dead interior foliage.
Parsons Juniper is a low, spreading shrub that tolerates moderate pruning. Remove dead or winter-damaged branches in spring and selectively thin overcrowded stems to maintain an open, layered form. Junipers regenerate from wood that retains some foliage, so cut back to a live lateral — never to bare, leafless stems.

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.
