How to Build a Deck Planter Box


Enhance the appeal of your deck with a homemade wooden planter. Depending on personal taste and space available, mount the planter on a railing or wall, or place it on the ground to enhance curb appeal and decorate the spot with a splash of color. It will allow you to relax by yourself or with family, or entertain friends while surrounded by aromatic flowers and foliage. Although home department stores sell readymade planters made from a variety of material, construct a simple wooden planter yourself and save up on costs.

Step 1

Measure the desired spot on your deck for the planter. Use a measuring tape and note the length, depth and width on paper. Also visualize how it will look mounted on the selected spot, and make changes in dimensions accordingly. Ideally, keep it up to 9 or 10 inches tall and 1 to 3 feet wide.

Step 2

Saw the wooden boards to size with a circular saw. Cut five boards for your rectangular planter so it has two identical long sides, a base and two identical short sides. Keep all five sides equal for a square planter. Also sand the sides of each board to make them even.

Step 3

Drill 1/2-inch wide drainage holes over the base piece. Drill them randomly over the surface, or in rows spaced equally apart.

Step 4

Place your base board flat on an even surface and hold a long board (the planter's front) against its long edge. Butt the corners so the joint is flush and even. Drill a line of four to five wood screws into the lower edge of the front board that penetrate the lower long side of the base to join both pieces together. Secure the structure with another wood screw or two if you feel it is rickety.

Step 5

Hold one of the short pieces (the planter's side) against one of the short sides of the base. Butt the corners so its top is level with the top of front piece, and the joint between the base and front is flush. Drill two or three woodscrews into its side to join it to the short edge of the front piece, and into its lower edge to join it to the base board.

Step 6

Repeat this process to secure the other long board (back of the planter) and your other short piece (side of the planter) to the structure.

Step 7

Lift the planter and inspect it for weak or rickety joints. Drill woodscrews where you feel your container garden benefits with additional stability. Also decide whether you want to paint it a natural or bright color, and do so appropriately with spray paint. Set it aside so it dries thoroughly before mounting it over your spot and filling it with soil and flowers.
