Answer: It's too late to feed your lawn again this fall; wait until spring. The seeds you broadcast will continue to germinate and fill in. If you're concerned that maybe you didn't use enough seed for the lawn to fill in quickly, you can over-seed again and water the area well to make sure the new seeds make good contact with the soil. They will germinate and set roots as long as the soil temperature remains above 40 degrees.
Best wishes with your lawn!
