How to Build a Wood Flower Box


Wooden flower boxes help create space in a variety of locations. You can use them in windows, on patios and porches, or as landscaping along walkways and steps. Building a wooden flower planter is not difficult and can be done as a short project during the course of a day. You can grow a large variety of flowers and herbs in a wooden planter.

Step 1

Set up two 48-inch boards and two 4-inch boards to form a rectangle with the sides of the long boards set against the edges of the short boards. Apply wood glue between the seams formed where the boards meet. Allow the glue to dry.

Step 2

Set an "L" bracket at the bottom outside edge of a corner. Drill screws into the bracket holes to attach the two boards at that corner. Set another bracket along the outside edge of the corner at the top of the corner. Drill screws into the bracket holes to complete the attachment of the boards at that corner. Repeat this process with the other three corners until all four sides are attached.

Step 3

Lay out the last board for the base. Apply wood glue to all four edges around the base. Set the completed rectangle around the base board. The two pieces should fit snugly together. Allow the glue to dry.

Step 4

On the inside bottom of the box, set one "L" bracket at each end of one of the long walls. Have the brackets resting against the inside wall and the base. Drill the screws into place through the bracket holes. Repeat this process for the other long wall of the flower box.

Step 5

Set two "L" brackets on the bottom inside wall of an end piece. Drill the screws into place. Repeat the process for the other end of the flower box.

Step 6

Turn the wooden flower box over so the bottom is facing up. Drill holes for drainage all along the base of the flower box.

Step 7

Paint or stain the flower box with a weather-resistant finish according to the manufacturer's instructions. Allow the stain to dry before planting flowers in the flower box.
