Yes, I understand about the quality of builder grade seed. That was what I was referring to when I stated that's all the local store carried.
I can keep it wet. We have lots of hoses and timers. Because of the straw beds we created the lawn areas are not too big and we can keep it wet without dragging hoses across the seeded areas.
Wow, it's a much simpler process than I thought it would be! Just need to find someone to aerate it for me.
