Well im in tulsa oklahoma and have a new to me house I bought. I would say my yard was about 60 percent crabgrass but I have a lot of that killed off now. I know I should have probably waited but oh well. I really cant put fescue in my front lawn because its 100 percent sun and it will fry in the summer. What else would yall recommend doing? Or do I have to wait to spring to get anything going?
