Tip #10: Irrigation Systems vs. Rain

Did you know that your irrigation system is supposed to supplement the natural rainfall? I bet logically you answered "yes." Reality is that a lot of people see their irrigation system as "how they water their lawn." You lawn is watered by the rain and your irrigation system is meant to just supplement that rainfall. My point is that this reinterates the importance of rain sensors and ET devices to ensure that you are always just "supplementing" the natural rainfall and not overwatering.
