Sod, or turf grass, is a pre-grown grass mat that is used to establish a lush, green lawn quickly. It consists of a layer of soil held together by grass roots and is typically harvested in rolls or squares for easy installation. Sod provides an instant lawn, eliminating the lengthy waiting period associated with seeding, and helps prevent soil erosion. Available in various grass types suited to different climates and uses, sod is an ideal choice for residential lawns, sports fields, and commercial landscapes, offering a beautiful, functional outdoor space right from the start.
