I did a small grade & seed job Saturday 7/17 for my brother inlaw. I called him up tonite to find out how it was going (he lives 1+ hours away) and he said it's coming in fine... 3+ inches already and thick. I told him to keep watering and hope it survives August
Luckily the conditions were ideal the last 2 weeks.
I used Lesco's stuff too. I also say to have a little more patience. How far down did the thatcher sow the seed into the ground?
Keep us updated... Good luck.
