Water sod after installing. Dried-out sod cannot establish strong root systems. Sod may take on a yellow, dead appearance if not kept watered. Keep the first inch of top soil moist or apply 1 inch of water every two to three days for three weeks after installing.
Rake up dead areas of sod to allow more light and air. Dead, matted areas of sod are more susceptible for contracting fungal diseases.
Fertilize sod when 50 percent of the grass has come out of dormancy or four weeks after installation. Spread a fertilizer with a NPK amount of 2-1-1 at a rate of 1 lb. of slow-release nitrogen per 1,000 square feet. Water the lawn after spreading the fertilizer. Fertilize again in six weeks.
Mow your sod when it reaches 3 1/3 inches in height. Take off 1/3 of the grass blade. By keeping your sod at 3 inches, you help maintain strong root systems.
Cut out damaged areas of sod with a sharp trowel. Lay a new piece of sod over the bare soil and cut the piece, so that it butts up against the surrounding sod. Keep the newly laid sod area moist, so it can establish roots.
