Water:

Only water every 7 to 14 days if we don’t get rain.
Water deeply (1”per area.)
It’s best to water in the morning. This helps to reduce problems with fungus.

Set your sprinkler:

For best lawn health in clay soil, sprinklers should be run for short times but repeated several times in the same morning, so water can soak in before more water is added. Water deep and then refrain from watering for 7 to 14 days to train roots to go deep.
