Make a Trellis Planter

Step 1: Cut the wood

Make the following cuts:

  • Six ¾- x 8- x 24-inch boards
  • Nine 1- x 2- x 32-inch boards
  • Two 2- x 2- x 6-inch boards
  • Two 2- x 2- x 14 ½-inch boards

Step 2: Assemble the base pieces

For this step you will need two ¾- x 8- x 24-inch, two 2- x 2- x 6-inch and two 2- x 2- x 14 ½-inch pieces of wood.

  • Attach two 2- x 2- x 14 ½-inch pieces to the top of the long edge corners of one of the ¾- x 8- x 24-inch pieces by drilling pilot holes from the underside of the 8-inch piece, then attaching with 2-inch deck screw through the bottom of the 2- x 2- inch piece.
  • Next, attach the two 2- x 2- x 6-inch pieces in the same manner to the other 8-inch base piece.

Step 3: Attach the front and back

  • Create the front of the box by placing the base piece with the 2- x 2- x 14 ½-inch board on its long edge side, with the 2- x 2-inch pieces supported.
  • Lay two ¾- x 8- x 24-inch boards on the 2- x 2-inch pieces flush together so that the bottom of one of the 24-inch boards is flush with the perpendicular 24-inch base board.
  • Attach each board to the 2- x 2-inch pieces with two 2-inch screws each, drilling pilot holes first.
  • Repeat with the other base piece, supporting the 2- x 2- x 6-inch pieces, to create the back of the box.

Step 4: Cut and attach the sides

  • Place the base pieces on a level surface with the 2 x 2-inch pieces pointing upwards, and the base boards flush along their length.
  • Measure the distance for the two remaining sides. The length needed should be 16 inches, but your opening may vary. Remember to measure twice, cut once.
  • Cut four pieces of ¾- x 8-inch wood the span of the sides and attach them as you did in the Step 3, with two 2-inch screws per end of each board, drilling pilot holes first. You should now have a completed box.

Step 5: Build the trellis

  • Lay the box on its back, with the 2- x 2- x 6-inch pieces on the ground.
  • Starting from the top, lay out three of the 1- x 2- x 32-inch boards so that they’re 3 ¾ inches apart, and centered on the 2- x 2-inch pieces.
  • Drill pilot holes, and attach each horizontal piece with a 2-inch screw to each 2- x 2-inch piece.
  • Add another set of three cross boards 8 inches below the bottom of the lowermost 1- x 2-inch piece you just attached, spaced and attached the same way.
  • Repeat these steps for the final set of three.

Step 6: Attach casters

Attach one caster to each of the four corners with 1 ¼-inch coated screws. If the planter box will be placed on a sloped surface, place the two locking casters so that they will prevent the box from rolling down the slope.
