Immediately After InstallationAs soon as your sod is installed, thoroughly water the sod. To ensure that you have watered enough, lift the sod to see that the water has soaked through and saturated the soil under the sod. Repeat your watering cycle if needed. This first watering is the most critical and will prevent problems later. Be sure your sprinklers are adjusted to provide even coverage. Many times the area between the sprinkler and its outside radius will not receive an equal amount of water due to an improper adjustment. This will result in damage to the sod in this area. To avoid problems, check and recheck your coverage! Keep the sod saturated for two weeks. This may take as many as 4 or more waterings per day or as little as one per day, depending on the weather. Be certain that your new lawn has enough moisture to survive hot, dry or windy periods. Water areas near buildings more often where reflected heat dries the turf. If you see signs of stress, it is most likely due to the lack of water. Increase water in the area, but do not allow water to form puddles. Gradually reduce watering two weeks after installation and refer to the general guidelines below. If your sod was installed before August 15th, apply a pre-emergent herbicide or a fertilizer with pre-emergent after installation on top of the new sod to prevent crabgrass from germinating in the ground underneath the sod. Avoid using anything containing the product Balan on new sod. To avoid causing indentations or air pockets, don't repeatedly walk or kneel on the new turf just after watering. It is not necessary to roll the new sod unless the grade underneath the sod is very uneven and lumpy.
