Why New Sod Turns Yellow
The blades turn yellow because the sod is dying from lack of water or because the sod roots have not made firm contact with the soil below. Water well. Press sod into the soil and water again.
Sod Turns Yellow
Yellow patches may indicate that your new sod is getting too much water. Typically, new sod requires five to 10 minutes of watering, two to three times daily for the first seven to 10 days after installation. Water enough to soak the first few inches of soil. In the second week, watering can be reduced to once daily, soaking about 1/4 inch of soil. Dog urine burns new sod and established lawns due to its high nitrogen content. If the problem is a neighbor’s pet entering your lawn, consider installing a fence or a shrub border to prevent easy access. Fertilizing new sod before this time will cause yellow patches to appear because the shallow root system of the new grass cannot absorb nutrients, and the nitrogen leaches into the soil.
