The weather has cooled considerably, in fact we had our first frost this morning. The day was lovely for working so I spent the day putting fall fertilizer on the lawn and reseeding bare spots. I also spread seed heavily in areas that have dense clover. While I don’t mind some clover, too much is not a good thing!
I am still cutting my lawn at summer height (as tall as my mower will go). While the weather is cool enough to lower the height, it is dry. Plus I think leaving your lawn long in the fall helps combat those weeds that like to germinate in the cool weather.
