When to prune kurume azalea 'hino crimson' 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 kurume azalea 'hino crimson'
Use sharp hand pruners to remove spent flowers and any stems that break the plant's compact outline. Cut back to a healthy lateral bud or branch. Avoid heavy shearing; this type looks best with its natural dome shape preserved.
Light pruning immediately after spring flowering is all that's needed. Hino Crimson is a compact, naturally mounding Kurume azalea and typically holds its shape well on its own. Prune right after blooms fade to avoid cutting off next year's buds. Remove dead or damaged wood any time.

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.
