Ten years ago, I made these exact cedar garden beds out of inexpensive cedar fence pickets for under $20 each. They are holding up well! You can also find the single width cedar garden bed plans here.
Preparation
6 - 5-1/2" wide cedar fence pickets (prefer not dogeared, but can use dogeared)
6 feet of 2x4 board, cedar or can be treated lumber
40 - 1-1/2" long self tapping exterior construction screws like these
For installation on soft surfaces like soil, gravel or lawn (includes staking system)
6 - Cedar 2x4 @ 12" - longest point measurement, one end cut at 30 degrees off square bevel (see step 1 for more information)
4 - 5-1/2" wide cedar fence pickets @ 70" if dogeared, if NOT dogeared, no need to cut
4 - 5-1/2" wide cedar fence pickets @ 35" if dogeared, in NOT dogeared, simply cut in half
For installation on hard surfaces like concrete, decks, or pavement or hard compacted gravel (no staking system)
6 - Cedar 2x4 @ about 11" - measure the width of a cedar fence picket and multiply by two (see step 1 for more information)
4 - 5-1/2" wide cedar fence pickets @ 70" if dogeared, if NOT dogeared, no need to cut
4 - 5-1/2" wide cedar fence pickets @ 35" if dogeared, in NOT dogeared, simply cut in half
Instructions
Step 1
Cut boards according to the cut list with a compound miter saw (preferred) or a circular saw.
Attach long fence pickets to the 2x4s, all outside edges flush (with exception of staking end), with 1-1/2" screws, two screws per joint.
Build two identical.
Step 2
Attach shorter fence picket pieces to the project with two screws per joint, all edges flush on outside and to the top.
On installation, adjust project to make sure it is square by taking opposite diagonal measurements and making sure the measurements match. Check cedar bed area for level.
Use a hammer to pound the stakes into the ground to secure the garden box.
