I have attached some photos of my first raised bed, currently under construction. It is in a crescent shape that is oriented so that it will protect the bee hives from the northwest winter wind. The plan is for it to be about four feet across at the base and six feet tall, or more if I can manage to get the soil up that high. We are doing this mostly without any mechanical equipment. I'm thinking of covering the wood in the photos with dirt and then stacking another layer of logs on top of that and covering that with the upside-down sod, more dirt, and some of hay/straw/manure compost. I'll just plant clover and some flowers on it this year and them add some bushes and vegetables next year.
The logs are red pine and Siberian elm. I'm located in mid-Michigan.
