Cut the boards as shown in the cut list using a miter saw.
Step 1: Assemble Back
Assemble the back by drilling pocket holes in the boards as shown and screwing together using 1-1/4" pocket screws.
Step 2: Install Sides
Install sides as shown using wood glue and 1-1/4" brad nails.
Step 3: Install Fronts
Install fronts as shown using wood glue and 1-1/4" brad nails.
Step 4: Cut French Cleat
To create a french cleat rip a scrap 1x4 board (about 24" in length) down the middle on a 45 degree angle.
Step 5: Install French Cleat and Hang Planter
Install one side of the cleat on the planter using 1-1/4" exterior screws and the other on the wall.
Note: Be sure to check for level throughout this step and if installing cleat into brick or cement you'll need a hammer drill and concrete anchors.
