When to prune mountain laurel 'olympic fire' 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 mountain laurel 'olympic fire'
Snap or snip off spent flower trusses by hand before seed set. Use clean shears to remove any dead or damaged wood back to healthy growth. Only reshape lightly — cut to a lateral bud or branch.
Mountain Laurel 'Olympic Fire' needs minimal pruning. After flowering, deadhead spent flower clusters to improve next year's bloom. Remove any dead, damaged, or crossing branches as needed. Avoid heavy pruning — it is slow-growing and hard cutting sets it back significantly. A light tidy after bloom is all that's usually required.

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.
