I suppose this isn't the most exciting question, but for me its pretty important. I'm located in south-central Maine and built a new house in the middle of a forty acres of woods. The contractor who was supposed to excavate the site and finish the yard couldn't finish up and now I can't get him back. Right now my yard consists of about 12" of sand. I'm going to try to finish it myself. I asked about buying topsoil. Now I've decided to buy a small, used backhoe with a front end loader and use the topsoil I already have. My question is - how deep should I make it. When I asked about buying it, I got quoted two prices - one for 3" and one for 6". Also, should I get a tiller to mix it with the sand that's already there? As you can tell, I don't know anything about landscaping. I'm just tired of paying for stuff and not being satisfied with the results. While I'm at it, my wife is wondering what type of bushes she can plant along the foundation to prevent soil from washing away (we have a slope of about 15 degrees). Thanks for any reply or other help. Please feel free to give any advise.
