The answer to 'how to install sod' is to carefully prepare the soil, lay the sod pieces, and water thoroughly. First, clear the area of any existing grass, weeds, or debris. Then, till the soil to a depth of 4-6 inches and level it out. Apply a layer of topsoil or compost to enrich the soil. Next, lay the sod pieces tightly together, staggering the seams for a seamless look. Once the sod is in place, water it deeply to help the roots establish in the new soil.
Proper installation and ongoing maintenance are key to a healthy, lush lawn. Sod should be watered regularly, especially in the first few weeks, to keep the soil moist. Mow the lawn at the proper height and fertilize as needed to encourage growth.
