When to prune cotinus coggygria 'golden spirit' in the UK

Prune cotinus coggygria 'golden spirit' in early to mid spring. 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.

There is no nesting-bird restriction that realistically applies to cotinus coggygria 'golden spirit', since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.

For maximum foliage impact, cut all main stems back to 30–45 cm above ground each spring (coppicing/stooling). For mixed foliage and flowers, remove only the oldest third of stems and tip back others lightly. Avoid summer or autumn pruning.

Annually for foliage display; every 2–3 years for flowering. 'Golden Spirit' (sold as Ancot) has luminous golden-lime foliage and performs beautifully as a foliage shrub. Prune hard in early spring to get the largest, most vividly coloured leaves, or prune lightly for smoke-like plumes in summer. Dead, diseased, or crossing stems should always be removed.

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.
