The best rule of thumb if you are unsure of how much or when to water is to observe your plants. If they are doing well, gradually cut back a bit to find the level needed. If plants start to look stressed, gradually increase water to keep the plants healthy. Remember too that water is only one factor in keeping plants healthy -- be sure to look at other potential reasons for plant stress, such as bugs, poor soil, too much shade or sun.

TABLE 1 - THE BASIC SCHEDULE PER MONTH  

• Lowest in the winter
• Tapering up in the spring
• Highest in the summer
• Tapering back down in the fall. 

The watering times given are estimates, based on an average irrigation system.  Your system may need more or less water.  Remember to observe how your plants are doing. 

Many winters have enough snow or rain to support your landscapes – including your lawn.  In dry winters give a little water – but not very often.  Do not operate your irrigation system in freezing temperatures.  In winter (November - March) only water between 10:00am - 2:00pm.
