To achieve this goal most spray head zones (sprinklers that do not rotate) need to run approximately 15 minutes and rotor zones (sprinklers that do rotate) need to run approximately 45 minutes. If you have much slope on your lawn areas you may need to run 2 cycles but with shorter run times on the zones.
1 For example, if the soil is damp to 4 inches (10.2 cm) below the surface and your goal is to moisten the soil to a depth of 8 inches (20.3 cm), you'll need to leave the sprinkler on for 30 minutes (2 x 15 minutes) each time you water.atering only when your grass really needs it encourages the roots to grow deeper, but only if you apply enough water each time to penetrate the root zone. 1  The most accurate way to determine the depth of the root zone is to dig a small hole and measure how far the roots go down.
