How to Build Wooden Flower Boxes

Wooden flower boxes can enhance the look of your indoor or outdoor container garden. You can build these boxes yourself and save some money. Once you're done, you can choose whether to plant a few flowers directly into the flower boxes or just insert existing plants in unattractive planters into the boxes.

  • Three 1-by-8-inch boards, 2 feet long, for sides and bottom
  • Rust-proof screws
  • Screwdriver or drill
  • Two 1-by-6-inch boards, 8 inches long, for ends
Stand up two of your 1-by-8-inch boards next to one another with an 8-inch gap between them. Set the third board over the first two and line up the edges to make everything flush.

Screw the boards together, placing screws every 6 inches through the top board and into the side boards.

Put one of the end pieces between the side boards and work it into place to begin to close the box shape. Screw two screws through the top board and into the end piece to secure. Repeat with the other end piece.

Reinforce the corner joints with two spaced-apart screws going through the side boards and into the end pieces.

Repeat Steps 1 to 4 to make as many boxes as you need.

Tips and Warnings

  • Make measurement adjustments as necessary for longer or wider boxes. You can also break the box into sections by inserting small boards (the same size as the end boards) and spacing them out inside the box before securing with screws.
