How to Build Wood Planters


Decorate a particular spot inside or outside your house with a wooden planter. Keep it square, rectangular or any angular shape and fill it with bushy, tall or cascading flowers or plants. Use good quality wood such as cedar, teak, pine oak or any wood of your choice, or use 1-inch thick plywood sheets cut to size. Depending on personal taste, place the planter box against your wall, or install it on your railing or wall to add color at varying eye levels.

Step 1

Cut the wooden boards to size with a handsaw, or purchase them pre-cut from your local hardware store. Cut five lengths for a rectangular wooden planter: two same-length boards to form the planter front and back, two same-length board pieces to use as the planter sides and a wooden board that is equal in length to the front and back and a width equal to the side pieces to form the planter base. Keep all the five boards the same size for a square planter.

Step 2

Sand the edges of each board to make them smooth. Drill 3/4-inch drainage holes in the base piece, spaced equally apart. Sand the surface around the holes to remove any splinters.

Step 3

Lay the front board on your table. Hold a side piece against its corner, aligning it so the tops are level and the joint is flush. Wear safety glasses and earplugs, and drill two wood screws to attach both the pieces together. Check to ensure the joint is secure, or drill another wood screw at the same corner.

Step 4

Hold the other side piece against the other corner of the front piece and align it so the joint is flush. Join it to the structure with galvanized wood screws.

Step 5

Place the back of the planter so it rests on the sidepieces and drill it in place with wood screws. Your planter should look like an open box.

Step 6

Flip the planter and place the base over the exposed area. Drill four wood screws per long side and two per short side to secure it in place. Turn it over again and rest it on its base.
