During the hot summer months, it can get too hot or dry for the cool-season grasses. When temperatures rise about 90 degrees, cool-season lawns can start to go dormant and turn brown until cooler weather and enough moisture reach the soil. During these hot summer months, we recommend watering 2-3 inches a week during the morning hours either by rainfall or irrigation.

During the cooler months, a healthy lawn needs 1-2 inches of water a week. When a lawn receives more water than normal, this allows moisture to build in the soil. Having too much moisture can bring diseases into the lawn. If possible, let your lawn dry out for the next couple of days and continue with the recommended watering instructions.
