Many people tend to give up on their lawn after summer with the mindset that the season is over and they can start over next year.  This is a bad mindset because now we have the best growing conditions of the year with cooler temperatures (or arctic temperatures like today), adequate rain, heavy dew, and days that can still give plenty of sun.

Now is the best time of the year to seed.  If you have thin spots or bare spots you have another good week or 2 to seed them.  I would not wait too much longer because this is Michigan and we might have 3 feet of snow on the ground next month.

You should be watering once a day for 7-10 minutes per zone with the rotary heads and 3-5 minutes per day with the pop up heads.  If we continue to have rain once or twice a week you can turn off your sprinklers.  If we go more than 2 days without rain, turn them back on.
