How to Build Garden Boxes for Plants

Overview

Container gardening allows you to grow plants and trees that may not be suited to your climate. Cultivating plants in planter boxes offers portability, allowing you to move them indoors when the weather cools or if you'd like to redecorate your patio. You can build garden boxes for plants with wood that's designed to withstand the elements and create a decorative cover with copper, tin or mosaic tiles. Marine or treated plywood is a good base for your garden boxes. Look for the appropriate plywood in and decorative elements at your local garden center.

Step 1

Measure and cut three 12-by-12-inch sections of 1/2-inch treated plywood. One of these sections is the bottom of your garden box and two are the sides. Measure and cut two 11-by-12-inch sections of the same wood. These sections are the remaining two sides of the box.

Step 2

Place the bottom panel on a flat surface. Mark each edge A, B, C and D. Attach one 11-by-12-inch panel perpendicular to the A and C sides of the bottom panel. The side panels should be flush with the bottom edge of the bottom panel that is resting on the table. Countersink the decking screws before you attach the two pieces together.

Step 3

Place the remaining two 12-by-12-inch panels perpendicular to the bottom panel on the B and D edges. Make sure that the panels are flush on all sides to complete the garden box construction. Countersink the screws before inserting them.

Step 4

Flip the box over and drill drainage holes in the bottom panel.

Step 5

Attach one 12-by-12-inch tin tile onto each side of the garden box with waterproof construction adhesive. Let the adhesive dry.

Step 6

Measure and cut four strips of copper foil to fit the top edges of your garden box. Attach the strips with waterproof adhesive.

Step 7

Cut a section of plastic liner to fit inside the garden box. Attach the liner with a staple gun.
