Answer: If you have already tried overseeding and aerating and they haven't worked, it may be time for a complete overhaul: rototilling, adding organic matter or top soil, then reseeding or installing sod. Sometimes it is just best to start over. You can renovate your lawn now by first rototilling, then raking out the debris, spreading several inches of organic matter over the top and tilling it in to loosen the soil, or adding topsoil to enrich your soil. Then rake smooth and either broadcast seeds or install sod (for an instant trouble-free lawn). Once your new lawn is up and growing, plan on watering as needed, mowing regularly and feeding your lawn in April, June, September and late November to keep it lush and thick. A healthy lawn will crowd out weeds so you won't have to regularly treat your lawn for these pests.
Best wishes with your new lawn!
