You'll want to dig out all the woodchips from beneath the soil surface. While woodchips are considered organic matter and when they decompose they'll release nutrients into the soil, a large quantity of wood chips can generate heat as they decompose which could burn the roots of your turfgrass if the chips are left in place. Plus, as they decompose the soil level will settle and you'll end up with a soggy area in the lawn. So, now matter how deeply they were set, you'll need to dig them all out before you proceed. You may need to bring in some topsoil after removing the wood chips. Once you've brought the soil level up to par with the rest of the yard, spread 2-3 inches of organic matter over the soil and dig it in. Then you can rake the area level, broadcast your seed and water it in well. Be sure the seeds are kept moist (water several times a day if necessary). The seeds will germinate in 7-10 days. Enjoy your new lawn!
