Water is the most important resource that insures this world’s existence. It is life and death; therefore, water is the key element to having a healthy, beautiful, lush lawn.
The most important thing to remember is that grass and sod does not waste water, people do.
Water is very important when installing new sod because it is a perishable commodity; therefore, it must be watered as soon as possible once it has been laid. The first few days of watering are critical! Your sod will start to establish itself in this time period and, “build up the subsoil moisture” that will help start the process of the roots knitting itself with the soil. The amount of water your newly laid sod needs depends on the depth of your topsoil. If you have only 4” of topsoil then you will water your sod until it is “soaked” all the way down to the clay, which holds the water. To know that your sod is getting enough water, use a long screwdriver to probe the soil to help determine the depth of the moisture (remember the depth you want to measure depends on the depth of your topsoil).
Be sure to keep you sod “soaked” for the first 10 to 12 days. You may have to water 3 to 4 times a day to make sure the sod blades and root zone stay moist, depending on numerous factors such as wind and temperature. After the two-week duration has passed your sod should be thoroughly knitted with the soil and already growing quickly. You should water your lawn every 2 to 4 days. It is better to apply 1/2 to ¾ inches at each application rather than lesser amounts daily.
The 3rd week is considered the transition period, where you go from watering daily to increasing the number of days between each watering. This is also the time when you can begin routine maintenance for you lawn. After your lawn has been fully established you can increase the number of days between watering depending on the season and the weather. Make sure to keep you eye on your lawn and use common sense to see if your lawn is dehydrated or not.
