When I bought my house, in the front yard there was a mound of dirt and tree stumps that had been there for over 25 years. I had a retaining wall built so I could flatten out the mound and make a bed. This weekend the mound was removed. What we found under all of it was rich black compost. I was fully prepared to amend the soil because I though the mound was going to be mostly sand and clay. Boy was I surprised!!! There was more than enough for the front and some left over for the back yard jungle I'm going to build.
Manna from Heaven!
