Laying down turf, or sod, is a landscaping job that involves placing strips of grass and soil over an area of land. It is often used to create a lawn or to repair damaged areas of grass. Sod is typically sold in rolls or squares and is made up of grass and soil. The process of laying down turf involves cutting the sod into pieces and then placing them on the ground in a pattern. Once the sod is in place, it needs to be watered and fertilized to ensure that it takes root and grows properly.
