Container gardening provides people who lack garden space or have poor soil conditions an opportunity to grow plants of their choice. A planter box is a form of container gardening that is popular with apartment dwellers and homeowners alike. Although different planter boxes made from materials such as wood, plastic, terra cotta, fiberglass, ceramic and metal are easily available in the market, making a wooden planter yourself will save you extra expense and allow you to customize it according to your needs.
Building a Wooden Planter Box
Decide the shape and size of the planter. Measure any particular spot you want to place it in so that you can determine planter length, depth and width accordingly. Note the measurements on paper so you know how much wood to purchase. Stick to a traditional rectangular or square planter box if you have not specified a particular spot where you want to display it. Keep it up to 9 inches high and no more than 3 feet wide.
Purchase five rot-resistant wooden boards that are an inch thick. Two long boards that are equally wide will serve as the front and back of the planter, two equally short and wide boards will be used for the sides, and the fifth board, as long as the front but as wide as the sides, will be the base. Sand the edges of the boards to make them smooth so that they are easy to handle when you begin assembling the planter.
Drill 1-inch drainage holes in the base, spaced 4 to 6 inches apart. Sand the surface on both sides, directly over the holes, to make them smooth.
Place the base piece on an even surface, and hold the back piece against it. Make sure the long edge of the back rests against the long edge of the base evenly and the joint is flush. Carefully drill 1-inch wood screws, spaced 6 inches apart, into the back. These will penetrate the base to hold both the boards together. Repeat the procedure to attach the front board to the structure.
Lower one of the short sides in place, positioning it so that it rests against the short edges of the front and back pieces and flush on top of the base. Drill it into place with 1-inch wood screws into both its sides and base. Repeat the procedure to attach the other sideboard to the structure. Your planter box is now complete.
Lift the planter to review it. Check to make sure all the joints are secure and that there are no sharp edges or corners. Make necessary adjustments by drilling wood screws into any joint for added stability, and rub sandpaper to remove any splinters.
