Build a ChoiceDek® Eight-Sided Planter

Are your pots ruining the natural beauty of your plants? Maybe your decor has evolved to the point that simple terra cotta won't quite do anymore. Save yourself the trouble and your treasured plants the shock of repotting. Making your own planter is a simple fix that's both functional and attractive. And, when you use ChoiceDek to make the planter, it's totally maintenance free. In one afternoon, you can have a unique decorative planter. Lowe's is happy to provide this information as a service to you.

Tools & Materials


  •   • Table saw
  •   • Mitre saw
  •   • Jig saw
  •   • Hammer
  •   • Tape measure
  •   • Drill/driver with bits
  •   • Dust mask
  •   • Goggles


  •   • 1 1/4x1 1/4 ChoiceDek balusters
  •   • 1/2" plywood
  •   • 3d finish nails
  •   • 1" wood screws
  •   • Wood glue

Critical Dimensions

  1. Each row of side pieces equals 3/4" of height for the planter.

Note that two rows of side pieces are highlighted. This represents 1 1/2" of height on the planter.

Example: If the planter needs to be 9" high, divide 9 by .75 to determine the number of rows. 9/.75 = 12 rows of side pieces.

  2. The number of side pieces in each row is equal to half the number of sides on the planter.

Example: If the planter has 8 sides, divide 8 by 2 to derive the number of side pieces needed for each row. 8/2 = 4 side pieces per row.

  3. The total number of side pieces required is equal to the number of rows multiplied by the number of side pieces per row.

Example: If the planter requires 12 rows and 4 side pieces per row, multiply 12 by 4 to find the total number of side pieces needed. 12x4 = 48 side pieces

  4. The length of the side pieces determines the maximum diameter pot the planter can hold. Use our chart to size the side pieces for your planter.

Cut the Side Pieces

  1. Rip the balusters into 1 1/4x3/4" pieces.

Make the first angled
cut in the right end of
the work piece.

Flip the work piece edge for edge before you make the second cut.

Use a stop block on the right side of the mitre saw to ensure uniform pieces.

  2. Set your mitre saw to cut a 45° angle to the left. Cut a 45° angle in the right end of one of the balusters, as shown in the illustration. Measure and mark the work piece for its second mitre cut. Flip the work piece edge for edge and make the second mitre cut.

  3. Unplug the saw and lock it into the closed position. Butt one end of the piece from step 2 against the saw blade and clamp a stop block against the other. With the stop block in place, all you need to do is flip the work piece, butt it against the block and cut to make uniform side pieces.

  4. Cut enough side pieces to complete the planter.

Assemble the Side Pieces

  1. Lay out the bottom two rows of side pieces as shown in the graphic. Glue and nail the pieces in place.

When viewed from the top, the the planter should look like this.

Install filler pieces in the top rim to give the planter a more finished look.

  2. Continue gluing and nailing side pieces until they are all assembled.

Cut and Assemble the Top Rim and Bottom

  1. Cut small pieces of side piece stock to fill in the top rim of the planter. Glue and nail the pieces in place.

  2. Trace the planter's outline on the plywood and use a jig saw to cut it out. Secure the plywood to the bottom of the planter with 1" wood screws.

  3. Seal the plywood bottom of the planter.

ChoiceDek Finishing Note: Left unfinished, ChoiceDek will weather to a beautiful grey patina. If you wish, you may apply paint, stain or a clear, topcoat finish to ChoiceDek. Allow the material to weather slightly before applying any finish.
