Step-by-step instructions
Assemble the rear wall frame
Lay the two 66-inch back posts parallel on a flat work surface. Position the 41-inch lower and upper back planter boards between the inner post faces, aligning the bottom board flush with the post base. Clamp the parts firmly while keeping the frame square.
Install horizontal trellis framing
With the rear frame still flat, place the 41-inch top trellis rail flush between the tops of the posts. Position the three 41-inch horizontal slats evenly between the upper planter board and top rail. Clamp all pieces securely against the post inner faces.
Assemble the front wall frame
Connect the planter side walls
Place vertical trellis slats
