Fall is here!
You should continue to water between rains through October. If you need your
irrigation system blown out, wait until November to have it done. There is no danger
of it freezing before early December.
Try to keep up with the leaves as they come down.
Continue to mow at 3" and do not nmow shorter until the final cut in early November.
The best thing for your lawn is to go into the winter short6 (about 2") and as clean of
debris as possible.
