Tall Fescue has no real way of spreading and reproducing itself like Bermuda grass or Zoysia grass does. Late August, September, and October is the best time of year to rejuvenate your fescue lawn. Fescue grows and develops in cooler temperatures much better than hot weather. We suggest doing the aeration and seeding while the soil temperatures are warm rather than waiting until late fall. The seed will need to be kept constantly moist for a much shorter period of time before germination if seeded early in the fall.
“By overseeding your Tall Fescue lawn annually, you are introducing new grass on an annual consistent basis, which will help to keep your lawn healthy, strong, and maintain its full, robust color for the upcoming year.”
