We have a tall fescue variant that is common in socal.
According to the UC Davis site below, the crop coefficient for tall fescue should be changed throughout the year in order to mirror actual water requirements.
The difference from the winter to spring and summer is rather dramatic and reflects what i have seen in terms of water needs for fescue in San Diego (in addition to the changes that Rachio already takes into account).
Is there a way to program this into the advanced settings of each zone, or would i need to just change it manually each month?
Thanks!!
I copied the data below that corresponds to tall fescue
