When to prune peony 'sarah bernhardt' 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 peony 'sarah bernhardt'
Remove spent flower heads by cutting the stem back to the nearest healthy leaf. In autumn, after frost kills the foliage, cut all stems down to 2–3 inches above the soil surface. Do not cut below ground or disturb the eyes (buds) near the crown.
Peony 'Sarah Bernhardt' needs minimal pruning. Deadhead spent flowers promptly to prevent energy going into seed production. In autumn, once foliage has yellowed and died back completely, cut all stems down to 2–3 inches above ground. Never cut back in spring or summer — the foliage is photosynthesizing and building next year's blooms.

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.
