How to Build a Box Planter


Container gardening has broadened the scope of gardening, allowing gardeners to plant and grow fruits, vegetables and plants in little spaces, indoors, or where soil quality is poor. A box planter is a popular form of container gardening that can be placed on the porch, in the garden or backyard, indoors or even hung outside a window. These can be made high to prevent a gardener from straining his or her back by bending low. Box planters also increase productivity, since every inch of space is exclusively for planting.

Step 1

Decide where to place the box planter so you can determine the appropriate height, width and depth. Ideally, it should not be wider than 3 to 4 feet so you can access the plants growing in the middle easily. Make sure the size of your box planter complements the area where it is to be placed. Take the measurements with a measuring tape, and note them down.

Step 2

Purchase pressure-treated wooden boards from your local hardware store according to your measurements, or cut them to size yourself with a circular saw. Although you can use a variety of material to make box planters, wood is widely used due to its natural appearance and ability to blend with the surrounding. You can select oak, pine, cedar, redwood or any other type of wood depending on your budget. You will need five identical wooden boards for a box planter- four sides and one base. You can also cut four small blocks to serve as 'legs' for the box; lift it off the ground to improve drainage.

Step 3

Hold one board on a flat, even surface and place another board flush against it. Make sure the tops and ends of both are at the same level. Wear your protective eyeglasses and earplugs and drill two 2-inch wood screws, one near the top edge and the other near the lower edge, to attach them together. Drill another screw in the center for added stability.

Step 4

Repeat the procedure with the two other boards to connect them together. To connect both the structures, hold them together so the sides that meet are flush against one another and at the same level. Drill 2-inch wood screws in both the corners of each structure to join them together. You will now have a box without a base or lid.

Step 5

Drill ½-inch drainage holes into the base piece, spaced at least 6 inches apart. Also place wood blocks, if any, on each corner of the piece and drill them into place with wood screws. Turn the box planter so its base-end faces upwards, and carefully lower the base piece over it. Join it to the structure by drilling two 2-inch wood screws on each side.

Step 6

Sand the box planter with medium grit sandpaper to remove any splinters or sharp edges. Apply a coat of paint to protect the box planter from natural elements, especially if placing it outdoors.
