After the box planter is assembled, cut brackets to support the weight of the planter, dirt and plants and secure to the home’s exterior. This design uses 2-inch thick wood and borrows a design already on the front porch. The brackets can be cut in any design desired, but this project uses the cardboard template to cut the notches necessary for the brackets to fit flush with the exterior surface.
Trace around cardboard template onto wood after determining the height and width for the brackets (Image 1). Use a handsaw to cut bracket curve and notches for siding profile (Image 2). Remove any marks with a sander (Image 3). Finally, countersink holes on each bracket's edge for screws to be added during installation. Repeat process to complete two additional brackets.
