How to Build Deck Planter Boxes

Overview

A deck is where a homeowner entertains guests, has cookouts, or just relaxes with a good book in hand. Planters with flowers, herbs or plants provide a touch of color and aroma to the deck, making it even more pleasurable. Grow planter herbs that you can simply pull off and add to your barbecue dinners, or grow annuals or perennials that will add a burst of color to the landscape, and make it visually appealing.

Step 1

Decide the size and shape of the planter so you can purchase wooden boards for it accordingly. You can have a small 8-by-8-inch square planter that will contain a small flowerpot, or a 2-foot-long planter with a 10- to 12-inch depth. The final size will depend on the area where it is to be displayed and the space available. Do not make the width more than 3 or 4 feet, or else reaching the plants in the center will be difficult. Write all the measurements down.

Step 2

Purchase five wooden boards for the planter box that you can cut to size with a circular saw, or have a professional pre-cut them. You will need five boards--two identical long boards for the front and back, two identical short boards for the sides, and a baseboard as wide as a small board but equal in length to a long board.

Step 3

Drill ½ to 3/8-inch holes, equally spaced, over the surface of the base piece that will assist in draining excess water out of the planter.

Step 4

Take one of the long side boards and place a short board flush against its edge. Hold it securely in place, and align the tops to keep them at the same level. Drill two 1inch galvanized wood screws into the long side that will penetrate the short side to hold them together. Place this L-shaped structure aside. Repeat the procedure with the other long side and short end to connect them.

Step 5

Join both the L-shaped structures by placing them in such a way that the long side of one is flush against the short end of another. Make sure the joint is flush and even, and drill 1-inch woodscrews to join them together so your structure resembles a box with no lid or base.

Step 6

Turn the box over so its base-side faces upwards, and carefully lower the base piece over it. Attach it in place by drilling two 1-inch screws at each short end and three per long side. Check the see the box is secure, and reinforce any joint by drilling a wood screw in place.

Step 7

Sand the surface of the box to smooth out any sharp edges or splinters, and apply a coat of exterior paint, or clear acrylic paint.
