Wood planter boxes do not have to be as complicated as the ones you normally find in home improvement instruction books or even on the web. A quick and simple planter can be constructed by anyone with nominal carpentry skills. Create them in any size, as needed for particular locations. Basic instructions take you through the process of building a 2-foot-long wood planter box to be placed in your garden or on a patio, deck or porch.
Measure two pieces of cedar wood, each 2 feet in length. Mark the measurements with a pencil. Cut the board pieces with a circular, jig or hand saw.
Measure and mark two pieces of cedar wood, each 8½ inches in length. Cut the boards along the marked lines.
Place the cut pieces of cedar into a frame shape. Do this by standing the two longer boards on edge, front and back, parallel to each other. Place the two shorter pieces of cedar between the longer ones, crosswise, one at each end.
Attach all four cedar boards together with rust resistant screws, the drill and a screwdriver drill attachment. Use four or five screws at each end of the longer boards, drilling them through and into the edges of the shorter cedar boards.
Put the cedar wood frame onto a piece of three-fourths-inch-thick plywood. If you don't have a scrap piece of plywood, check for a small piece at a lumber yard or home improvement center. Mark around the cedar frame, onto the plywood, with your pencil. Cut the plywood at the markings.
Place the cut plywood atop the cedar frame. Screw the plywood piece to the edges of the frame, using a screw about every 4 or 5 inches.
Remove the screwdriver attachment from the drill and replace it with a round drill bit. Work several holes, spacing them randomly, through the bottom plywood for easy water drainage.
Cut two pieces of wood from scrap lumber, each 2 inches wide and 10 inches long. Screw them into the bottom plywood piece at each end of the wood planter box. Use three or four screws, across the strip of wood, at each end. This will allow easy drainage of excess water if the planter is placed on a non-porous surface, such as cement.
