How to Build a Narrow Planter Box

Raised garden beds provides superior soil drainage for the plants grown inside. Constructing a wooden planting box provides edging for the bed, which reduces soil loss from erosion while also giving the bed a finished look. Full-sized raised beds aren't suitable for all garden applications. Borders, areas along walkways and other small spaces require a narrow box that holds no more than a single row of plants. Construct the box frame to fit the measurements necessary for your proposed growing site while making it wide enough to provide sufficient space for the plants.

Instructions

    • 1

      Measure the length of the planting site. Cut two 2-by-8-inch boards to the measured length using a circular or handsaw. These are the side boards.

    • 2

      Cut two lengths of 2-by-8-inch board to use as the end boards. Cut the lengths so they are 12 inches long for smaller plants and 16 inches or longer for larger plants.

    • 3

      Lay the side boards on the ground, placing them upright on their narrow side. Set the 12- to 16-inch end boards on either end of the sides, so their edges overlap the ends of the side boards. This leaves an 8-inch space between the side boards if you use 12-inch end boards, or a 12-inch space with 16-inch end boards.

    • 4

      Nail the boards together, forming a box. Use two nails per each corner to ensure the boards are securely attached.

    • 5

      Set the box in the desired planting site. Fill it with high quality garden or potting soil and plant it as desired.
