So I have grass replanted in one zone this spring and now when it’s hot days in Seattle I’m seeing few brown spots appearing on the grass. I suspect that might be due to Rachio expects roots to be 6 inches and in reality they might not be that deep (grass is still quite thinnish).
Now i have AD set to 50% and root depth to 6 inches. If I reduce root depth or AD irrigation duration dials down. That shouldn’t really promote root growth as the irrigation would happen more frequently (with 80-90F daily most likely every day).
What is the best plan here? Also I’d like to do a water cup test, how much water should I expect too see in it after one cycle with those settings (AW is 0.11)
I have 0.6 inch precip rate rotary nozzles which are quite overlapping (bad sprinkler design from 90s), so I don’t think it’s a coverage issue.
