Answer: Use a vegetation killer (such as Round Up) to kill existing weeds. Once you've killed the weeds you?ll want to remove them, then rake and remove any other debris such as sticks and rocks. The soil should then be tilled thoroughly, either by a mechanical tiller or digging down a spades depth over the entire area. Spread 4-5 inches of organic matter over the area and rototill it in, then rake the area smooth. Sod produces an almost instant lawn because the grass is mature with a healthy root system. After laying the sod and watering it down well, it only takes a week or two to become firmly established. Seeding takes a little longer, but the results are eventually the same - a lush, thick, healthy lawn.
