With warmer weather finally arriving, many gardeners are preparing to tackle overgrown hedges and shrubs. However, experts caution that one common gardening task could lead to significant fines. Noah Mabey, Senior Gardener at Thornbridge Hall, warns that May marks the peak of bird nesting season across the UK, and heavy pruning should be avoided until September.
Legal Risks of Pruning During Nesting Season
Under the Wildlife and Countryside Act 1981, it is an offence to damage or destroy an active bird's nest. Gardeners must thoroughly inspect hedges and dense shrubs before cutting. Violations can result in severe penalties. Noah, also Horticultural Advisor to Platinum Spas, emphasises: "Even in the smallest gardens, wildlife finds a way. I've discovered nesting birds in busy garden areas, including a blackbird's nest right by my potting bench."
Safe Gardening Tasks in May
While heavy pruning is off-limits, lighter jobs such as deadheading flowers or gently trimming soft growth are permissible. The key is to always check plants carefully before starting. Noah advises: "Taking a moment to check properly can make all the difference during this crucial time for wildlife."
Rules for Pruning Neighbouring Plants
In the UK, you have a common law right to prune branches or roots encroaching into your garden up to the boundary line. However, you cannot trespass onto your neighbour's land or damage the tree's health. Protected trees with Tree Preservation Orders (TPO) or those in conservation areas require council permission.
Key Legal Rules for Pruning
- The Boundary Line: You may only cut up to the boundary line. Exceeding this or cutting down the tree could lead to charges under the Criminal Damage Act 1971.
- Trespass: You must not enter your neighbour's land to prune; work only from your side.
- Waste Disposal: Cut branches belong to the tree owner. You must offer to return them; throwing branches onto their property may constitute fly-tipping.
- Protected Trees & Areas: Check with your local council for TPOs or conservation area status.
- Wildlife and Countryside Act 1981: It is illegal to intentionally destroy an active nest. Avoid major pruning between March and August.
- High Hedges: Complaints can be made if a hedge exceeds 2 metres in height and affects light or access, per GOV.UK guidelines.
Gardeners are urged to exercise caution and prioritise wildlife protection during this sensitive period.
