I did a project about 3 weeks ago for a guy. We killed off his front lawn with round-up then waited about 2 weeks and I used my bobcat to scrap off the old grass and smooth it off. Then we laid new fescue sod on the front lawn and some bare spots in the back lawn. Will it has been about 3 weeks since we laid the sod and the front lawn hasn't took yet. The back lawn is fine and you can't pull it up, we didn't roundup anything in the back lawn. The front though you can pull up with little resistance. We have had a lot of rain lately and the sod looks great the roots just are not growing. Any advice would be great. I'm afraid when it gets hot the sod will just dry up without any roots.
