I am just curious about how much is to much water. My yard is about 80% shaded and I am starting to get some moss, mushrooms and some possible red thread. I have approx 11 zones and I have had them all set for 20mins a zone, 5 says a week skipping Wednesday and Sunday. Is this two much or not enough. I did make a adjustment last night cutting down to 10mins in the shaded zones and a little more in the sunny zones. Any help appreciated.
