Answer: Fall is a good time to start a new lawn. I'd suggest starting small rather than trying to revamp an entire acre. With that said, the best approach is to remove the weeds, either by digging or by using a non-selective herbicide such as Round-Up. After killing the weeds, rototil the area and rake to remove the weeds and their roots. You can amend the soil with organic matter, till again, then rake to level the area. Broadcast grass seeds, cover with a thin layer of peat moss to keep the seeds from drying out. Water as often as necessary (several times a day) to keep the seeds moist. They should sprout in 7-10 days. Once the grass is growing, water every few days to keep it green. Mow when it reaches 3" in height. The roots will continue to grow until the ground temperature drops below 40F. Next spring it should spring to life. Enjoy!
