How many inches per week are you irrigating???
How often do you do the Sumagreen apps???
1.5" a week total (every other day schedule) late afternoons so foliage can dry out before nightfall. Leaf wetness can be an issue here over 10 hours in the Valley. Soil drainage is excellent here on the test lawn.
Rutgers suggests Midnight - 6am best watering times to avoid the 10 Hour wetness rule of thumb.
I only made 1 Sumagreen application.
