Planter boxes are great for small garden spaces and to add as an architectural element under a windowsill or on a patio. You can plant anything in them, whether it is herbs, flowers, fruits or vegetables, or even a combination or companion plants. Building a planter box requires a good amount of materials and some time and patience, but it can be less expensive than purchasing planters at your local gardening store.
Wear the gloves, eyewear and dust mask before starting work to protect yourself, as the saw can kick up dust into your face, and you do not want to risk harming any fingers.
Make the back and front of planter box by using the table saw to cut two pieces of wood from the 6-foot by 1-inch by 8-inch board. Each piece needs to be about 30 inches long.
Make the planter box bottom. Use the saw and cut one 30-inch-long piece from the 4-foot by 1-inch by 8-inch board. With the bevel of the saw at a 10 degree angle, chop the wood so its diameter is 5 inches at the thickest part.
Make the planter box sides. Use the saw to cut out two pieces from the wood scraps that are 5 to 6 inches in diameter and 6 inches in height. Use the saw to trim off any awkward angles.
Lay out all the pieces (the front and back, the bottom and sides) and fit them together. You may need an additional set of hands to help hold the planter box steady. Use wood glue to secure the pieces.
Use the drill and drill bits to make the planter box drainage holes. These holes need to be distributed evenly along the bottom of the planter box, about 1/3 to 1/4 inch in diameter.
Use the sandpaper to smooth all rough edges or angles on the planter box. You can stain or paint the box, just make sure to use water resistant sealant.
