Plans for a Simple DIY Cedar Raised Garden Bed that’s about eight feet long and four feet wide, making the middle easy to reach from either side. Made of rot-resistant wood, this garden bed will last many seasons.
Materials for a raised bed:
One 6-foot-long 4-by-4 ($15)
Six 8-foot-long 2-by-6s ($75)
One 10-foot-long 1-inch PVC pipe ($3)
Two 10-foot-long ½-inch PVC pipes ($6)
32 3½-inch #14 wood screws and 16 ½-inch #8 wood screws ($29)
One 4- by 10-foot roll of ¼-inch-mesh hardware cloth ($15)
Eight 1-inch galvanized tube straps (semicircular brackets; $3.60)
32 cubic feet (1 1/5 cu. yd.) soil mix ($100 in bags; look for combination of topsoil, compost, and potting soil).
With a table or power saw, cut the 4-by-4 into four 16-inch-tall corner posts. Cut two of the 2-by-6s in half. Cut the 1-inch PVC pipe into four 12-inch-long pieces and the ½-inch PVC pipes into 6-foot-long pieces. Assemble pieces on a hard, flat surface.
Build bed upside down. Set a 4-foot 2-by-6 on its thin edge on pavement, and place a 16-inch post at one end. Secure post with two 3½-inch screws. Repeat at other end of board. Repeat with other short board.
Join short sides with an 8-foot board; and secure with two screws. Add other long side. Add second layer of 2-by-6s.
With help from a buddy, flip the bed right side up. Move it into position in the yard, marking with a trowel each corner post’s location. Move the bed aside; dig a 5- to 6-inch-deep hole for each post.
Put the bed back into place, with posts in holes; fill around posts with soil.
Rake the existing soil at the bottom of the bed to level it, then tamp it smooth. Line the bed with hardware cloth to keep out gophers and moles; trim the cloth with shears to fit around corner posts
Fill the bed with a planting mix of topsoil, compost, and potting soil; rake it smooth, and moisten it with a gentle spray from the hose.
