Answer: If you decide to redo the entire lawn, start by rototilling the area to break up the soil. Remove any debris (stones, sticks, weeds, etc.) and then 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, rolling it and watering it down well, it only takes a week or two to become firmly established. This approach should improve the soil beneath the lawn and help your lawn grow lush and thick. Spring and fall, when temperatures are cooler are the best times to renovate your lawn and lay sod.
