One of my best lawns has been distroyed by concrete contrators. The yard is Fescue (well, now 1/2 fescue and 1/2 dirt). It is very hot and dry now here in Okla. (105 degrees 2 days ago) I am very hesitant to put down fescue seed or sod right now due to the high temps as there is no irrigation. Is there another grass that could be recommended to grow in this area? (95% shade).
