Gardening expert Monty Don has revealed the correct time to prune hedges, warning that cutting them too early could harm nesting birds and even lead to legal consequences. The broadcaster and author, best known for presenting BBC's Gardeners' World, emphasizes waiting until late summer or winter to ensure bird safety.
Why Pruning Too Early Is Dangerous
Many UK birds, including robins, house sparrows, blackbirds, and wrens, build nests in hedges during spring and summer. Trimming hedges in spring or early summer can destroy active nests, killing chicks or causing abandonment. Monty Don previously stated on X that April is "the very worst time to cut hedges" due to young birds still being in the nest.
Legal Implications
The Royal Horticultural Society (RHS) warns that disturbing nesting birds is illegal under the Wildlife & Countryside Act 1981. It states: "Before undertaking work on hedges, check that there are no nesting birds in the hedge, as it is an offence to damage or destroy the nest of any wild bird while it is in use or being built." Violators could face fines or prosecution.
When to Prune Safely
Monty Don advises that the "best times for birds are winter months and late summer when all are fully fledged and left nests." For summer pruning, late August is typically safe, as most fledglings have left the nest. The RHS acknowledges that regular trimming is necessary for hedge health but stresses the importance of timing.
Tips for Hedge Maintenance
The RHS recommends hand-held hedge shears for small hedges and powered trimmers for larger ones, including corded electric, battery-powered, or petrol models. Weight is a key factor when choosing equipment, especially for extensive hedging. Monty Don, who began his television career in 1989 on This Morning and has authored over 25 books, continues to share practical advice through social media and his series, including 2026's Monty Don's Rhineland Gardens.
