How to Build a Wooden Planter Box

Overview

A wooden planter box is a form of container gardening that provides homeowners, apartment dwellers and office workers a chance to enjoy beautiful annual, perennial or biennial flowers, plants or herbs. People place their planters indoors, or on patios, decks, gardens, against a wall outside, or even mount them from a railing or wall to add color to a spot. The natural appearance of wood allows it to blend with the surrounding easily. However, depending on personal taste, it can be stained a bright color so it stands out and attracts attention.

Step 1

Measure a particular spot you want to place the planter over, so you cut wood to size accordingly. Note the dimensions of your planter on paper, including the length, width and depth. Keep it high to prevent back problems when bending too low, height between 7 to 9 inches and width no more than 3 to 4 feet.

Step 2

Cut five lengths of wood with a handsaw according to your desired dimensions. Use five identical boards for a square planter, but a rectangular planter needs two long boards, two short boards and a base as wide as the short sides. Sand the edges of the boards with medium grit sandpaper.

Step 3

Drill ½- to ¾-inch drainage holes in the board that serves as the base. Depending on personal taste, drill these in equally spaced rows, or randomly. Sand the area over the drainage holes.

Step 4

Lay the base on your work table. Place the front of the planter (long board) flush against it, so its lower, long edge rests against the long edge of the base. Butt the ends and join both the pieces with evenly spaced wood screws. Repeat the procedure to attach the back of the planter (long board) to the other side of the base.

Step 5

Place the wooden side board (short piece) between the ends of the front and back, so it rests flush against the base. Secure it in place by drilling two wood screws at each side and its base. Repeat the procedure to join the second short side to the other end of the structure so the planter box is complete.

Step 6

Apply a coat of clear paint to the planter to retain its natural appearance, or use a bright color for added decoration. The paint protects the wooden planter from moisture damage, so it lasts many years.
