I just read this thread, and I have treated lawns in Springfield MO. Namely the Taco Bells, and Golden corrals Up till a year ago. Most every lawn up there should be treated as a fescue lawn weather it has Bermuda mixed in or not. Fecue does real well in that area.
As for the weeds, even in the 1st year those are easy to control and shouldn't be there. Now if it was Dallisgrass I could live with a few clumps...
