Use a tape measure and pencil to mark the planks at twelve 20" increments. Use a miter saw to cut a 45 degree angle on all ends so they fit snugly when assembled. You will need three planks for each side of the board. planter box, twelve in all.
Mark, measure, and then use a miter saw to cut the 2x2 into four 15” pieces. These will be the inside and vertical corner supports for the planter box.
To assemble the first side of the planter box, lay three boards side by side on a flat surface, then center two vertical support boards along the inside of each mitered edge. Attach these boards to the boards with the nail gun. You can also place a strip of wood glue along the edge before nailing for extra strength.
Working from the bottom up, continue adding boards and 2x2s to build the remaining sides. Fasten with glue strip and nail gun until box is complete.
Measure, mark, and cut two pieces of 2x2 that will serve as the bottom support rails. Turn the box on its side and secure these rails to the inside of the planter box with a nail gun.
Turn the box upside down and attach three planks to the bottom rails with a nail gun. Be sure to leave a little space between the boards for drainage.
Once the bottom boards are in place, turn the planter box over (right side up) and sand lightly with a fine grit sandpaper. It is best to paint or stain the planter box at this time. If you are painting, use an exterior paint that includes primer so the wood will wear the paint well and be protected from the elements.
Using the house number template as a guide, first decide on the location, then pre-drill all the holes with a 1/8” drill bit. Attach template to planter with painters tape for best accuracy.
Once all holes are pre-drilled, remove the template, then secure the house numbers to the planter box using a cordless drill and hardware provided.
