There is a lot of benefits of having a sprinkler system and using it the right way, a lot of people think you have to water 5-7 days a week and they do that only to see their yard is not looking good, we have learned that a deep soaking of the grass 1-2 times a week in a dry season gives you the best results! The reason for that is it makes the roots run deep and healthy! The roots of the grass are going to be what gives you the grass you want to see, and also keeps fungus from growing in your yard. Fungus gross in moist environments and if you are watering 5-7 days a week you are creating a place for fungus to grow. Also what helps with your grass is cutting it at a true 4 inches! These two things paired together can help you get the lawn looking the way you want it to! We suggest that you do that deep soaking of the lawn either late at night 9-11pm or early in the morning 3:30-6:30am so that the heat does not take all that water away. It has time to really soak in and get down deep in those roots if you do it at the coolest times of the day!
