Rake up the dead sod using a spring-tined rake. By removing the dead grass, you allow air and water to penetrate the root system.
Water your sod in the morning. Give your sod 1 inch of water a week to help it bounce back from the dead. Ensure your sod gets enough water each week by placing a tuna can in the yard. Measure the amount of water in the tuna can to see if you need to supplement the water.
Fertilize your sod four to six weeks after installing with a fertilizer that has an NPK amount of 2-1-1 at a rate of 1 lb. of slow-release nitrogen per 1,000 square feet. Apply fertilizer every six weeks throughout the growing season.
Mow your sod when it reaches 3 1/3 inches in height. By allowing your sod to grow to 3 inches, you help the root system establish and promote healthy grass growth.
Distribute a fine layer of grass clippings across your sod after mowing. Grass clippings decompose and contribute important nutrients, like nitrogen, that encourage healthy sod growth.
