Before You Begin
If you’d like to grow climbing vegetables in your new planter, we recommend using cedar wood. Cedar is naturally resistant to mould and great for organic gardening. Before starting, you should also download the plan and familiarize yourself with the project.

1
Build the Base of the Box

  • 1.1Cut three 46" pieces from the 5/4x6 boards for the base, then cut two 16.5" pieces from a 2x2 board for the legs.
  • 1.2Place three 5/4x6 boards beside each other and join them by using 2 1/2" treated wood screws to attach a 2x2 piece to each end.

Finish Building the Box

  • 2.1For the sides of the box, you’ll need to measure out and cut eight 5/4x6 boards:
    • For the front and back: Four 48" boards
    • For the sides: Four 16 1/2" boards

    Note that the box will be two boards tall.
  • 2.2Arrange the boards for the first row, starting with the boards for the sides and finishing with the front and back. Use a square to ensure 90° corners and use 1 1/2" treated wood screws to attach the side boards to the edges of the 5/4 base boards.
  • 2.3Cut 2x2s into two 6’ pieces and two 10" pieces.
  • 2.4Attach the two 10" 2x2s to the front corners of the box using 2 1/2" treated wood screws, standing them vertically to strengthen the structure. Attach the 6’ 2x2s to the back corners in the same way.
  • 2.5Secure the second-row boards to the vertical 2x2s.

Assemble the Trellis Frame

  • 3.1Cut two 2x2 boards into a 43" piece and a 46" piece.
  • 3.2Put the trellis frame together:
    • Frame bottom: Screw the 43" 2x2 piece horizontally inside the vertical 2x2s.
    • Frame top: Screw the 46" 2x2 piece horizontally at the top of the vertical 2x2s.
  • 3.3Cut ten 1x4 pieces to a size of 62". Using 1 1/2" treated wood screws, attach five of the pieces to the back of the trellis frame. Ensure that the pieces are spaced out equally by placing one on each end, one in the middle, and one between each of the ends and the middle.

Install the Chevron Pattern

  • 4.1Cut 40 2x2 pieces to a size of 11".
  • 4.2Starting at the top, make a mark every 5 1/2" along the vertical 1x4s with a level or a long ruler.
  • 4.3Starting at the bottom, attach the 11" 2x2s using 1 1/2" treated wood screws at an angle following the marks. Screw from the back to ensure a solid and secure hold. Repeat up to the top for each chevron zigzag, checking as you go that the chevrons are parallel.
  • 4.4Attach the five 62" 1x4s with 2 1/2" treated wood screws to the chevron joints. This will hide the joints and keep the 1x4s firmly in place.

Pro Tip

Since the 1x4 piece hides the cuts on the chevrons, you can keep things simple and cut them at a 90° angle. If you prefer to cut them at an angle, then trace their diagonals onto the trellis (step 3.6) to establish the cut angle. Use a sliding T-bevel or a protractor to measure the angle at the 1x4 vertical joints and transfer the measurement to your mitre saw.

5
Final Touches

  • 5.1Use a staple gun to attach a geotextile sheet inside the planter box.
  • 5.2Use a utility knife or scissors to cut away excess fabric.
  • 5.3Extend the life of the planter box and trellis by applying a wood preservative to every cut surface.
