I finished my raised bed last night. I say "night" because by the time I was done, I was using the driveway floodlight to read the level, which as it turns out is not a good way to level anything.
The construction was simple and cheep. The whole process involved:
- two 1x8x96 planks, ceder
- two railing posts, ceder
- decking screws
- shovel
- screw driver
The railing posts make up the corners. There is nothing special about these posts, other than price (less $1.50 each). Cut in half, they were the perfect length. I dug 1-foot holes and buried them to keep them from moving. This was the hardest part of the process; apparently digging holes is hard, which I suppose means that I made a good career choice in computers.
Home depot cut the planks down into 3ft and 5ft lengths so they would fit in my car. A few wood screws and they were attached to the posts. They made up the raised edges of the box, resulting 3ft x 5ft x 8in, or 10sqft.
Over all, I am very happy with the result.
