How to Build a Wooden Planter Box

This stripped-down window planter can be built in less than an hour, yet the simplicity of the design resists rot far better than traditional window boxes.

Draw the circles, then cut

You can put together this simple window planter in less an hour. For each planter, you'll need three 6-in. clay pots, 3 ft. each of 1x10 and 1x3, and 2 ft. of 2x8.

Cut the 1x10 and 1x3 to length (see photos for dimensions). Pot diameters vary, so size the holes by scribing and cutting out a 6-in. circle from cardboard to ensure that the pot will rest on its rim (Photo 1). Keep testing until you find the size. Then lay out and cut the openings.

Use a 5-gallon pail lid to scribe the bracket curves (Photo 2). Make sure the grain runs parallel to the shelf for strength. Smooth off the rough edges and paint the parts before assembly—especially if you want the two-tone look. Then screw the parts together with 2-in. exterior screws.

Mount the shelf to the wall by screwing through the hanging strip into the wall framing.
