The answer to 'how to install sod' is to properly prepare the soil, lay the sod, and care for it until it becomes established. First, clear the area of any debris, weeds, or old grass. Loosen the soil to a depth of 4-6 inches and add any necessary amendments like compost or topsoil. Level the area and compact it lightly. Next, unroll the sod pieces and lay them in a staggered pattern, pressing firmly to ensure good soil contact. Water the new sod immediately and keep it moist (but not soaked) for the first 2-3 weeks as the roots establish.
Proper installation and maintenance are key for sod to thrive. Be sure to mow the new grass at the recommended height and avoid heavy foot traffic until it's well-rooted, usually 2-4 weeks after installation.
