What is the Watering Index?
- An easy guide to using your irrigation controller when watering your yard.
- Inform you of how much water your yard requires.
- Provide you with monthly values that will adjust the time your yard is watered.
On the 1st of each month change the % key on your controller to the appropriate value for the month:
November is time to shut off your irrigation system for the winter!
Where do the WI values come from?
- These are percentages based on historical plant water needs data (evapotranspiration).
- Program designed by John Wynn.
What are the benefits of participating?
- Using less water can result in:
- Lower water bills
- Less mowing because excess water accelerates lawn growth.
