Overview

Planters are a form of container gardening that enable home owners to display a burst of color almost anywhere--indoors and outside. They decorate any particular spot where they are placed and stand out against any backdrop, enhancing visual appeal and interest. Planters are made from a variety of material such as wood, concrete, terra cotta, heavy-weight plastic, fiberglass and metal. You can easily make concrete planters at home and save up on extra costs in the process. Plant herbs, shrubs, annuals or perennials in them and enjoy their sight and smell wherever you place them.

Step 1

Decide the shape and size of your concrete planter. If you have any particular spot in mind, measure its length, width and breath and make the concrete planter to fit accordingly. A depth of up to 12 inches is more than enough for most plant roots to spread and grow. Note your measurements on paper. You have to make two plywood boxes between which you will pour the concrete.

Step 2

Use the measurements to cut your 1-inch-thick plywood sheet to size. Depending on the shape of your planter box, you will need two identical long sides (for the front and back), two identical short sides and a base piece for a rectangular planter, or five equal boards for a square planter. Drill a 1-inch drainage hole in the center of the base piece.

Step 3

Assemble the box by attaching the sides and base together with nails. Measure and mark lines for the second box on the plywood sheet that will be at least 2 inches smaller overall than the box you just made. Cut over the lines carefully with a saw, and nail the base piece and the sides together. Also drill a similar size drainage hole in the center of the base piece of the second box.

Step 4

Apply or spray a coat of oil on the inner walls of the larger box, and the outer walls of the smaller box. This will make it easier to remove your planter from the molds once the concrete cures.

Step 5

Follow manufacturer's instructions to mix concrete with water in a wheelbarrow. Insert the plastic pipe into the drainage hole in the larger box, and carefully pour 2 inches of concrete over the base. Spread it with a hand trowel so it is even.

Step 6

Lower the smaller box into the bigger one, aligning it so the drainage plastic pipe extends through its drainage holes as well. Gently press it down so it settles in place. Pour concrete between the walls of both the boxes, until an inch below the rim. Tamp it down to remove any air pockets.

Step 7

Leave the mold overnight so the concrete dries and sets in place. Carefully remove the smaller box when the concrete has dried. It should slip out easily because of the oil. Turn the planter over and slide the larger box out. Your concrete planter is ready.
