Okay so I have been reading a lot but could not find exactly what I was looking for. I got a call 2 days ago. He guy has about ten trees that were removed and the stumps were grinned out. there were some ash, maple, and oak trees I believe He wants to put grass seed where all the wood chips are. I have never done this and i have a few questions. If i were to remove the wood chips how deep should i go with top soil, and what fertilizer should be used to ensure that the seed comes in nice. Thank you in advance for the help.
