When the hedge has grown approximately two metres in height, it is layered, so forming an impenetrable barrier, along the side of boundary ditches, ideal tracks for foxes.

Hedge laying is a country skill, typically found in the United Kingdom and Ireland, which, through the creation and maintenance of hedges, achieves the following:

the formation of livestock-proof barriers;
the rejuvenation of existing hedgerows by encouraging them to put on new growth and helping to improve their overall structure and strength;
the affording of greater weather protection to crops and wildlife;
the provision of aesthetically pleasing screens to fields and gardens.
