Gardeners can now safely tackle hedge trimming without the worry of breaking the law, according to Monty Don. The renowned expert says August is the perfect time for this task, as the vast majority of nesting birds have fledged.
Why August Is the Best Time
Writing on his website, the Gardeners' World presenter explained: "It is safe now to trim hedges in the knowledge that the vast majority of nesting birds have fledged." He advises inspecting branches for any remaining active nests before starting.
Under the Wildlife and Countryside Act, it is illegal to damage or destroy an active wild bird's nest. Trimming in summer also produces "slower, less vigorous regrowth" compared to winter, helping hedges maintain their shape for longer.
Tips for a Perfect Trim
Monty recommends trimming the sides first, ensuring a slight outward slope from top to bottom to allow sunlight to reach lower branches. "Finally, cut the top, using a string strung between canes as a guide," he added.
Cuttings from deciduous hedges can be mown up and added to a compost heap, while evergreen trimmings should be disposed of via local council green waste collection.
Additional Benefits
A summer trim prevents rapid regrowth that can encroach on paths and windows. It also stimulates new side shoots, creating a thicker, denser hedge that improves air circulation and reduces fungal issues. Avoid heavy pruning during extreme heat or prolonged dry weather to prevent plant stress.
For those seeking the next job, Monty suggests cutting long grass or wildflower meadows in August, allowing flowers to set seeds and bulbous foliage like daffodils to die back naturally.
