Proper watering is essential in maintaining a healthy, vigorous lawn. Follow these guidelines for proper watering: For established lawns, apply 1 to 2 inches of water at each irrigation. Water every 23 days (in hot, dry areas) to 10 days if it does not rain. If the lawn wilts (see Drought), water immediately. Water newly seeded lawns lightly and frequently until the roots are established. The lawn will use more water in hotter areas, or where there are tree roots near the surface. Water less often during cloudy and cool weather, and more often during hot and windy weather. Measure the amount of water you apply with several straight-sided cans scattered under the sprinkler. Check to see if you are applying enough water by digging a hole with a trowel a couple of hours after watering. The water should penetrate at least 6 inches. Apply the water slowly enough that it does not run off. If you cannot change sprinkler heads, turn off the sprinklers for 30 minutes whenever runoff occurs. Continue this cycle until you have applied enough water. Aerating (see Compaction) will improve penetration.
