The main cause of an overwatered lawn is unattended sprinklers. Also, rain and high level of humidity can cause excess water in your yard. In this case, you need to create a proper drainage system and implement proper soil aeration techniques to remove excess water and encourage root growth. Besides, a good watering schedule is vital for establishing a healthy lawn. Create proper watering habits while checking for the signs of watering. It is recommended to water your lawn early in the morning before the sun so that it can absorb excess water.
