Too much watering causing root rot

I have had a Gen 1 Rachio for years but I can’t figure out my back lawn. It’s on a flex daily schedule but during the spring / summer (the hotter it gets) it will actually die from too much water… how do I fix this?

From my testing and observation, dial down the “crop coefficient.” Check the calendar to see how often that zone gets scheduled as you go. That is like a master amount slider. The “allowed depletion” will determine whether the master amount is metered in more short cycles or fewer long cycles.


Yes, try reducing the crop coefficient by 10% and see how that goes. If still overly wet, decrease another 10 etc.
