I recently had a 100 year old tree cut down and the stump grinded out. This left a big hole in my lawn, not to mention a lot of sawdust. I removed most of the mulch and sawdust from the area by hand. I was wondering what I could do now to help the area grow grass, cool season turf type fescue or bluegrass, in the damaged area? What are the necessary actions to take to insure that I have pretty green grass by spring. How much will the ground settle, ect. All comments appreciated.
