Sod is a layer of soil that is held together by the roots of grass. It is often used to create lawns, gardens, and sports fields because it provides a quick way to establish a green area. When you lay down sod, you get an instant lawn that can be enjoyed right away, unlike planting seeds, which takes time to grow. Sod comes in various types, depending on the kind of grass used, such as Bermudagrass or Kentucky bluegrass. It is typically harvested in large rolls or squares, making it easy to transport and install. Proper care, including watering and fertilizing, helps the sod establish itself in its new environment.
