I live in Michigan and want to construct a raised garden in only location
in yard where I get enough sun. this will be about 500 sq ft area. Need to
raise because of poor drainage. I picked up some treated 2x10's for this
project, and some 4x4's I was planning to cement into ground and nail
together. My neighbor advised me that frost would likely force the cemented
4x4 posts up. He said to use crushed rock and not cement. any advise
appreciated.
