I have been seeing a lot of dry lawns during my travels around West Michigan. A lot of us have turned our irrigation systems down or off since the weather has cooled off. Me included. So I guess this is just a reminder that your lawn may need a drink until we get significant rain fall.
Also, this is the perfect time to seed your lawn. If you do overseed, make sure to keep your irrigation running until it is time to turn it off in the Fall.
