Laying turf, or sod, is a landscaping job that involves placing grass and soil over an area of land. It is typically done to create a lawn or to repair an existing one. The term 'lays turf' is used to describe the process of laying down sod, which is made up of grass and soil. Sod is cut into strips and then placed on the ground in a specific pattern. Once the sod is in place, it is watered and fertilized to help it take root and grow.
