This DIY wooden planter box is perfect for spring, adding a fresh and natural touch to your home or garden. Whether you’re planting colorful blooms or vibrant greenery, this budget-friendly project is a wonderful way to welcome the season.
Materials:
- 3 – 1×8 cedar boards, cut to the desired length (for example, the width of your window)
- 2 – 1×6 cedar boards, cut to 7-1/16” (the true width of a 1×8 board)
- 2” exterior decking screws
Step 1: Attach the Front Board to the Bottom Board
To start your wooden planter box, gather your materials and focus on creating the base structure.
- Prepare the Boards: Choose the front board of your planter box from your cedar planks, selecting the smoothest side to face outward.
- Form an L-Shape: Position the front board upright and align the bottom board perpendicular to it, smooth-side-down, creating an “L” shape.
- Secure the Corners: Check the alignment at both ends, then predrill holes about 2” in from each end of the bottom board. Insert screws to connect the two boards securely.
- Reinforce the Attachment: Flip the boards over to form a tent shape, and add screws along the length of the connection, spacing them 6”-8” apart. For added stability, predrill holes to prevent splitting.
Step 2: Attach the Back Board to the Bottom Board
With the front board secured, it’s time to attach the back board to create the framework of your wooden planter box.
- Align the Back Board: Take the back plank and position it so the smooth side faces inward, matching the smooth interior of the front board. This ensures a polished look for the inside of your planter.
- Secure the Corners: Predrill holes about 2” from each end of the bottom board, aligning the back board at a 90-degree angle. Insert screws to secure the corners.
- Reinforce with Additional Screws: Add screws along the length of the back board, spacing them about 6”-8” apart for stability.
Building your own wooden planter box is a simple and rewarding project that adds charm and functionality to your home. Once completed, you can customize it with stain or paint, mount it securely, and fill it with your favorite flowers or plants.
