The front yard was planted several days ago. Here is a progress report.
The front yard was watered morning and evening for 20 minutes for 7 days. No sign of sprouting. There was a rain shower and sprouted blades appeared the next day. The backyard was planted the day after the shower and watered the same way. It rained (not a lot) on day 3 and again on day 4 (all day). Sprouts appeared on day 5. I think that rain is better than tap water for growing grass. It is growing up fine now. And we also seem to be getting rain nearly every day. At lunch time it was steamy.
