Grass-cutting to be reduced in Derry parks to support local bee population Project being implemented across the local area Mayor Brian Tierney pictured at Drumahoe District Park at the launch of the Don't Mow, Let it Grow Campaign, with Cllr Hilary McClintock and Kitty Hepburn, Drumahoe Community Association. Reporter: '); Grass in many public areas of Derry will be cut less frequently this summer. It's all part of a project being managed by Derry City and Strabane District Council to nurture and increase the local bee population. The Don't Mow, Let it Grow initiative will see reduced grass cutting in some areas of local parks and cemeteries over the summer months while free wildflower seed packets will be distributed to the public to encourage them to do the same in their homes.
