Best Time to Water. The best time of day to water your lawn is in the early morning, from 6:00 to 8:00 a.m. Watering in the morning gives wet blades of grass time to dry out over the course of the day, reducing the possibility of fungal problems. Morning is also the coolest and least windy time of day, which means that the water you apply is less likely to be lost to evaporation.
While essential for growth, too much water can harm new grass.

While new grass needs water to grow and establish deep roots, too much water can cause problems that end up hurting your grass. Learning how to properly water new grass and spreading out your watering throughout the day will help you avoid these problems.
