I want to raise the level of my lawn as much as 2 feet in places. I now have a large quantity of somewhat composted wood chips and I am wondering if I can use them as fill to raise the ground level and provide a good soil in which to sow a lawn.
“It is not a good idea to use only wood chips to raise the grade of an area,” says Greg Stack, University of Illinois extension educator, horticulture. While wood chips may raise the grade for a while, over time they will decompose and eventually the site will sink. Even using them as fill and putting soil over them is not a good idea.
“I would not use straight compost by itself to raise the lawn level, but mix it with soil,” adds Stack.
