Roll the entire surface of the new sod immediately after laying it to make sure the underside of the sod contacts the soil evenly.
Water the sod strips thoroughly to fully saturate the sod, paying special attention to the edges of the sod strips because they will dry out quickly. Water until the top 2 inches of soil beneath the sod feels completely saturated.
Check the sod every day, especially the seams. Water the sod enough to keep the soil evenly moist. Do not water to the point of making puddles, however.
Continue this watering schedule for two weeks, making sure the seams stay evenly moist to facilitate thorough knitting to the soil.
Check the seams after two weeks to see how the sod is knitting to the soil. If you cannot pull the sod back from the soil, decrease the watering schedule to two or three times each week.
