Use vinyl lattice to make a trellis that is lightweight.

How to Attach a Lattice Panel to a Plant Box

by Mary Lougee

Building a trellis on a plant box for growing a vertical garden allows you to tend plants without bending over, and it creates an area to hide items in a lawn such as a well house or a propane tank. Planting flowers or vegetables gives you a wind block as they grow and fill in the lattice panel. Attaching a lattice panel to a plant box creates a trellis that will support heavy vines and greenery.

Put on safety glasses and gloves for protection from wood splinters.

Measure the inside rear of a plant box with a measuring tape, horizontally. Measure the inside rear wall of the plant box’s height. Determine how tall you want the lattice panel to be above the rear vertical wall. Add this amount to the vertical height.

Mark a lattice panel with a carpenter’s pencil with the horizontal and vertical measurements. Cut along the pencil lines with a jigsaw using a fine-tooth metal blade.

Cut two pieces of lattice cap molding 2 inches shorter than the vertical height of the lattice panel. Cut two pieces of lattice cap molding the same horizontal length as the lattice panel.

Insert both vertical sides of the lattice into the lattice cap molding to form the sides. Place the two other pieces of lattice cap on the top and bottom to form the top and bottom of the lattice. The side pieces should be inside the top and bottom pieces to form a complete frame. Insert one 2-inch-long galvanized screw into each corner junction on the left and right top and the left and right bottom.

Place the lattice panel inside the planted box’s rear wall. Place a C-clamp on each side of the lattice near the top rear edge of the planter box to hold it steady.

Drill 1/4-inch pilot holes through the planter and the lattice about 1 inch from the top and bottom of the back wall on the left and right side.

Screw a 2-inch-long galvanized screw through each pilot hole from the rear. Remove the C-clamps and fill with potting soil.

Transplant your seedlings or seeds at the bottom of the lattice using the same spacing as if they were in a flowerbed or garden.

Weave the growing tips of vines in and out of the trellis openings as they grow longer.

Items you will need

  • Safety glasses
  • Gloves
  • Measuring tape
  • Carpenter’s pencil
  • Jigsaw
  • Lattice cap molding
  • Drill
  • 8 galvanized screws (2 inches long)
  • 2 C-clamps


  • Using a fine-tooth metal blade on a jigsaw prevents the lattice from splintering or tearing as you cut it.
  • Place large plant boxes in the area you want them to remain in before filling them with soil. Large boxes become very heavy after they are full.
  • Choose a plant box with drainage holes in the bottom, or drill 1/4-inch holes about 3 inches apart in each direction.


  • Keep children and pets away from your work area when you are using power tools.
