How to Make a Large Planter


A planter is a form of container gardening that allows apartment dwellers, home owners and office workers to incorporate plants and flowers where garden space is unavailable, adding color and visual appeal to the particular spot. Planters range from several inches in length to several feet, depending on the space available. Large planters lined against the exterior wall of a house, deck or patio is sufficient to provide color and beauty to the surrounding landscape.

Step 1

Decide the size and shape of your large planter and select material for it. A rectangular planter that is 3 feet long, 2 feet wide and 1 foot deep is a good size to work with, providing ample greenery and easy to maintain. Although planters can be made from a variety of materials such as fiberglass, terra cotta, wood, heavyweight plastic and ceramic, wood is usually preferred due to its natural look and ability to blend with the surrounding. Purchase good quality wood such as cedar or redwood since they are naturally rot-resistant and will last a long time.

Step 2

Wear your protective eyeglasses and earplugs and cut the wood boards to size with a circular or handsaw, or have a professional at the hardware store do it for you. You will need two 1-foot-by-3-foot boards for the front and the back, two 1-foot-by-2-foot boards for the sides, and a 2-foot-wide base piece that is 3 feet long. Sand the boards to remove any splinters.

Step 3

Place the front board on an even surface. Hold one of the side pieces flush against one of its edges, making sure the joint is even and smooth and both the tops are at the same level. Drill two 2-inch galvanized screws into the top and bottom edge of the front board that will penetrate through the side piece and hold both boards securely together. Once joined, the two boards will resemble an L-shape. Repeat the process with the back board and the second side piece. You will have two L-shaped structures.

Step 4

Join both the L-shaped structures in such a way that the short side of one is placed flush against the long board of another. Hold the joint firmly in place and drill 2-inch galvanized wood screws, one near the top edge and the other near the lower edge, to connect one side together. Repeat the procedure with the other side so you have a box shape that does not have a lid or base.

Step 5

Take the base board and drill 1-inch drainage holes, spaced 8 inches apart. Turn the planter over so its lower side faces up, and lower the base board over it so it rests on the edges evenly. Drill it into place with galvanized woodscrews, two per short side and three or four per long side.
