I know unfortunately things didnt go as planned. I have been keeping it moist plus there is the benifet that there is lot of shade in this area. It might be ok.Delmarva Keith said:You can use Carfentrazone (Quick Silver) 7 days after emergence. Don't use any surfactant. It will just burn off the top growth of the weeds but you can manage the weeds that way until the grass is old enough to handle stronger stuff for any weeds not killed.
Cool season grass planted this late (end of May?) is a pretty big gamble. Actually almost a sure thing that it won't make it. Do the best you can with it, lots of water, but don't be disappointed if it declines and dies. Reseed late Aug / early Sept.
