After installing new sod, follow certain steps to properly care for the lawn to ensure strong root development. The sod must establish itself onto the soil beneath it and the roots must penetrate down into the soil to create a strong, healthy lawn. Wait at least two to three weeks before walking on the new sod. Proper watering, mowing and fertilization of your new sod are crucial to lawn establishment and growth.
Water your new sod immediately after it's installed. Use a sprinkler or spray-nozzle attachment on your hose to water the sod and the top 2 inches of soil beneath the sod, ensuring even and thorough water distribution.
Water your new sod lightly for five minutes about four to six times each day during the first two weeks. Watering lightly but frequently will help the roots get both the oxygen and water they need to develop.
Cut back on watering for two days before mowing the sod for the first time. Your first mowing should occur about two weeks after installation.
Mow your new sod with your lawn mower set at a slightly higher setting. Aim for cutting no more than 1/3 of the total grass height at one time.
Water the sod less frequently but for longer periods after the first two to three weeks. Gradually reduce the watering frequency to one or two deeper watering sessions each day during the first growing season.
Feed your new sod at least four to six weeks after installation. Apply a 25-3-6 NPK (nitrogen-phosphorus-potassium) lawn fertilizer according to the directions on the package.
