When to prune pieris japonica cavatine 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 pieris japonica cavatine
Clip spent flower clusters to just above a healthy bud with clean scissors or secateurs. Remove any damaged stems back to the nearest healthy sideshoot. Make angled cuts just above a bud to shed rainwater.
Cavatine is an exceptionally compact dwarf — typically under 60 cm tall in 10 years — so it almost never needs pruning for shape. Deadhead spent flowers after blooming to keep it tidy and redirect energy. Remove any dead or damaged stems cleanly. Avoid hard pruning; Pieris responds poorly to cutting into old wood.

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.
