Planters are an ideal addition to any landscape or garden, whether you are attaching them below a window or keeping them on a patio. They can be used to grow everything from herbs, fruits, vegetables and flowers. Building a planter requires a good amount of materials, some time and patience. The key thing to keep in mind when building a planter box is to make sure you measure everything correctly, and to firmly secure the wood together to make it last for years.
Put on the protective eyewear, heavy-duty work gloves and dust mask before you begin working in order to protect yourself. Use the circular or table saw to cut two 30-inch-long pieces from the 6 foot x 1 inch x 8 inch wooden board for the front and back of the planter box.
Cut one 30-inch long piece from the 4 foot x 1 inch x 8 inch wooden board for the bottom of the planter box. Place the saw's bevel at 10 degrees and tear the wood so it is 5 inches wide at its widest part.
Cut two parts from the wooden scrap boards for the sides of the planter box that measure 5 7/8 inches wide and 6 3/8 inches tall. Trim the wooden pieces so they taper from 5 7/8 inches at the top to 5 inches at the bottom.
Lay out the wooden pieces for the planter box and practice fitting them together, making adjustments as needed by trimming along edges.
Use wood glue and clamps to secure the wooden planter box pieces together. If necessary, pre-drill countersink holes through the front and back pieces. Use the 1 1/2 inch screws to screw the pieces together.
Create drainage holes in the bottom of the planter box by using the drill to make about eight 1/8-inch holes around the edges and the middle of the bottom of the box.
Stain and seal the planter box if desired, or paint it to match your house, garden and give it a personalized touch.
