When to prune oxeye daisy in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune oxeye daisy
Snip off spent flower heads before seeds set, or shear the whole plant back by two-thirds after flowering. In late autumn, cut all growth to ground level. Note: check local guidance — Leucanthemum vulgare is considered invasive in some regions.
Oxeye daisy is a vigorous, prolific self-seeder. Deadhead spent blooms promptly if you want to limit spread — it can become invasive in garden borders and meadows. If naturalising, leave some seed heads. Cut plants back hard after flowering to tidy and reduce re-seeding. Cut to ground in late autumn.

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.
