Grass for heavy shaded area
I am a new homeowner living in Northern Illinois. There are several areas on my lawn that contains dead spots. Basically, there's no grass and it's just dirt. Most of these areas appear to go from medium shade to heavy shade.
What should I reseed these area with. I currently have what appears to be bluegrass of some kind now. The medium shade area is under a tree and is on a high area. Traffic is low (basically no one walks there). The heavily shaded area is under some dense tree and is sitting in a low area, so it gets flooded when there's heavy rain. The neighbor's kid and his dog walks by it may be twice a day and squirrel run around the area, so I guess it's lightly traffic. Should I try some sort of Fescues blend? Would it look weird against the Blue Grass?
