This is to be our first year trying to grow things in our raised beds. Over the past month or so we have built the Taj Mahal of raised beds. Not honestly sure what will be going in there just yet, but whatever the missus decides, that will be it. Both of us have reached the stage where it's difficult to bend, so this first raised bed is literally that. It is lifted up right off the ground. And by the way, given that we've never done this before I welcome your suggestions and criticisms so that we may improve in future. This small area is on the lowest of three "benches" if you will, and from the south edge the land falls away very rapidly. So the room available is fairly limited. Since a picture is supposed to be worth 1,000 words...here goes. That assembly is about 16 feet long and the "fingers" go out for 8 feet or so. First thing I did, after drilling a few hundred drain holes, was to add a layer of drain rock throughout. Next came the filter cloth, followed by topsoil.
