So I have been on a quest for a couple years to find an easy to make Raised bed. I have tried several different patterns. Used several different materials. First using 4×6 timbers, then using fir and cedar, and concrete wall block. I stumbled acr0ss this pattern at the Farmers Market. One of the booths had these for sale in several colors and a couple of different types of wood.
After a little investigation I found that these beds where easy to build, easy to assemble, and best of all inexpensive. Not only are they easy to build but replacing a worn out section is simple. Each 8ft beds take 3 2″ x 8″ x8′ and four 8″ galvanized spikes. The wood should be untreated pine or oak. I used pine because it was easy to obtain and work with, but for longer lasting beds oak would be better. I would not use treated wood, the salt used to cure this would can leach and effect growth in the garden and enter the food you are growing.
Tools you might need: an electric hand drill, and 1/2″ drill bit, a box saw, a skil saw, a measuring tape, a square, a pencil, gloves, 1 1/4″ bit, a hammer, and rubber mallet.
I have included a video that may be helpful in making cuts and assembly. The pattern is easy. You measure each board to lenght. In the video I am make 48″ square beds, but 8ft beds require the exact same cuts. A squre bed uses two board instead of three.Then measure in from the end 1 1/2″ then measure 3 5/8″ to the center of the board. Connect the lines When cut the result would be an L. Repeat on both ends of the board. When complete the board would look like a T. Repeat on all four of the boards.
Once all four boards are cut set them together so overlaps are alternating and you have a square. At this point you may need help holding the boards to drill holes in the corners. The bit will not reach all the way throught the boards unless it is 8″ or longer. If this happens drill all the corners, when finished drill the unfinished hole the rest of the way through. Take the spikes and place in the corners to check fit. They should come a little over 1/2″ out of the bottom. Disassemble and move to the final location. Start to finish about 30 to 45 min.
Till next time good Gardening!
