Building wooden plant containers is a quick and easy way to add style or color to your landscaping. Decks, patios and front porches offer a location to garden with a single plant container. Build your planters a bit larger and deeper to use them for a container vegetable garden. Use a rot-resistant wood for outdoor projects, such as redwood, cedar or cypress.
Measure and mark two lengths of 18 inches on a piece of lumber. Always wear safety glasses, before cutting wood. Cut the board at the marks. These two pieces are the front and back of the plant container.
Measure and mark two lengths of 10 inches on the remaining piece of lumber. Cut the board at the marks. These two pieces are the sides of the plant container.
Measure and mark one length of 16½ inches on the remaining piece of lumber. Cut the board at the marks. This piece is the bottom of the plant container.
Lay the bottom piece of wood on its edge, lengthwise. Spread glue on the right and left sides. Press a side piece at each end, creating a squared C-shape. Allow the glue to dry for about four hours.
Use the screwdriver attachment and drill to adhere the screws all the way through the bottom of the side pieces and into each of the edges of the bottom board. Use four or five screws on each side, evenly across where the boards have been glued together.
Place the glued boards so that the bottom piece is flat on your work surface, with the two sides straight upward. Spread glue on all the edges, both sides of the bottom board and the two side boards. Press in place the front and back boards, one on each side. Allow the glue to dry for about four hours. Gluing the plant container together makes it easier to attach the screws.
Attach the front and back permanently to the container. The screws will go through the front board and into the edges of the side board and bottom board. Use a screw about every 3 to 5 inches.
Drill five or six holes through the bottom board with a round drill bit. These holes will allow any extra water from the plant soil to drain. This is important because excess water left in a puddle at the bottom of the container can cause plants to get root rot.
