SEE IT FROM YOUR LAWN'S PERSPECTIVE.

 

As the days get shorter, your landscaping needs less water. By September, plants naturally enter into their dormant phase until next spring. The shorter days also mean that less water is lost through evaporation, regardless of daytime temperatures. So dial back the water by 30 percent. You'll still have a beautiful yard and save a boat load of water to boot.

Schedules assume heavy clay soils common to most of IRWD's service area.  Generally, these are the MAXIMUM times you will need for full sun areas.  Start with this schedule and adjust the times only if your plants show the signs of stress.  If stress occurs only in isolated areas, check the operation of your irrigation system before adjusting times.

By "cycling" the irrigation controller to turn on for the recommended number of minutes an hour apart, deeper watering and healthier root growth are gained, while runoff is reduced.

Some irrigation controllers have a feature by which the watering times can be set by changing the percentages instead of specifically entering the days, cycles and minutes.
