After your lawn has been installed, it is important to water the soil for at least 10 to 12 days. Water should penetrate the soil 4 to 6 inches, so a long screwdriver can easily reach the ground.
After the sod has been laid, water all areas. Watering should be scheduled to ensure that the sod remains moist and water penetrates to the soil at least 4 to 6 inches.
Additionally, you should keep this going for between 10 and 12 days, until roots are formed. Your new lawn can suffer severe damage if the sod layer becomes dry before roots form. Your sod should be watered if you notice any signs of dehydration, such as foot printing or the blue-gray coloration of your grass blades.
After the roots are attached to the soil, water every 2 – 4 days. The soil type, root depth, topography, wind, temperature and humidity will all affect the frequency and amount you water. It is better to water the soil less frequently, but to a depth of 4 to 6 inches.
Applying less water daily can cause root growth to be shallower and decrease drought resistance. To ensure proper water application, check with your sprinkler manufacturer or installer.
Winter watering should be done approximately every 3-4 weeks depending on the weather. This is especially essential if you have sod installed in the fall.
