I'm looking for suggestions on building a program for fall overseeding. In the past I've tried a fixed time program for each zone, but the soil ended up being too wet on days that weren't too hot or we had rain. I've tried building a program with weather adaptive watering on and I ended up getting dry areas because the controller determined there was a water surplus and didn't run the program. Yes, it was correct in that 1" down the soil was nice and moist, but the top layer was bone dry and I had all my freshly germinated grass died.
I'd love to get some recommended values or a program from people out there that have solved this issue. I can't be the only one that does fall overseeding! Is there any way to desensitize the weather adaptive watering so that the soil stays nice and moist without over watering freshly planted seed?
