Instructions
Attach Board to Studs
To install a wooden window box with brackets, first cut a pressure-treated 1x8-foot board to the length of the window box minus two inches. Attach the wood board to studs. The bottom of the window box will be half an inch below the bottom edge of the board—decide on the height of the board based on where you want the bottom of the window box to sit.
Editor's Tip: For the best visual effect, your window box should be at least as wide as the window, but should not extend more than three inches beyond the trim on each side.
Attach Brackets and Corbels
Attach brackets six inches in from each end of the wood board to hold the box. For architectural flair, add decorative corbels (painted or stained the same color as the window box) to the bottom of the brackets.
Secure Window Box
Set the box into the brackets, making sure it is seated properly before planting into it. Fill the window box with high-quality potting mix; add plants. For a dynamic window box look, go for a mix of tall and trailing plants for a variety of heights and textures.
