Cut off the top part of the cedar picket fence. This isn’t something you have to do; we just decided to square off the top to make it look a little cleaner.
Measure the cedar fence pickets. Cut 2 boards in half. Each post was 6 feet long, so we cut each in half to make two 3-foot boards. These will be the ends of each raised bed.
Take two of the long pieces of cedar, lay them next to each other, and line up the ends. Place one of the 10 inch long 2x4s cut in half (or 1x2s) to one of the ends of the long cedar boards and drill in. Stand it up with the cedar board touching the table; the ripped 2×4 is up and part of it is above the cedar.
Place the short end piece next to the long piece creating a 90 degree angle and screw it into the ripped 2×4. Continue doing this until all four boards are attached.
Add the second layer of cedar posts and screw them into the ripped 2x4s.In the center of the long side of the raised bed, screw in another ripped 2×4. This helps add support so it doesn’t bow out once the soil is added.
Put them in place and add soil.When installing the raised beds, it is a good idea to allow enough space between each bed to make it comfortable to walk through and bend down.
