Lawns - Grass not thriving after tree removed...

I had a large tree removed in our yard. The stump was mulched in place. A landscaper smoothed it out and added 4-6 inches of Topsoil and then seeded. However, in every place the mulch was, the grass is not growing well at all.

I am guessing that as the mulch decomposes under the topsoil, it is giving off some chemical that is stunting/killing the grass. Is there some sort of fertilizer I can use to fix the problem?

Thanks!

Yep..you are correct...if most of the ground stump was left in the ground thats what the problem is. It should have been hauled off then soil added, even then, the feeder roots left after grinding can cause problems. Many places reccommend pulling the stump if possible instead of grinding.

I can't remember whether the decomposing wood sucks all the nitrogen out or puts too much in. Pretty sure it sucks it all out since thats one of the tricks to speed up stump decomposition, put some high nitrogen fertilizer into drilled holes.
