*Irrigation is not usually required in winter months because rainfall provides sufficient water.

  • Divide the recommended number by the number of times a week you are watering.
  • Cool season grasses require more frequent watering than warm season grasses because their root systems are not as extensive. Divide the required weekly minutes into about 3 equal irrigations, evenly spaced throughout the week. Fewer applications may be sufficient during cooler months. Desert areas, slopes or areas with shallow soils also need shorter, more frequent irrigations than warm season grasses.
  • Be sure to monitor your sprinkler system to make sure you are getting uniform coverage. Repair and replace broken sprinklers as necessary.
