1). The #5 setting on the Billy Goat is the amount of seed dropping, not the depth. My depth was between 1/8" and 1/4" depending on the uneven terrain. 2). I have an in ground irrigation system. Normally I water for 35 minutes on each zone 3 times a week to get ~ 1" of water (deep watering, fewer times). My system puts out 15 ga/min. For keeping the seed moist I set it for 10 minutes per zone, 3 times a day/ 7 days a week at 10:00 am, 1:00 pm and 5:00 pm. This is roughly 50% more water/week but way more often to keep the seed moist. 3). 85% of my lawn has very well established grass. It was 100% before the drought. In the areas (15% of lawn) that we bad I increased the seeding rate. Thus the reason I ran out finishing the rest of the lawn. 4). I believe there is plenty of cover (dead grass) to help protect the seed. The slit seeder made the rows to drop the seed in and after a few waterings that laid back down. So it is nor "bare" dirt, but rather daed grass covered area. Keep suggestions coming BTW, It does get real hot in Minnesota.
