- Exterior paint or sealant
- Tape measure
- Circular saw
- Drill and driver bits
- Clamps
- Safety glasses

Design Your Planter Box
First, decide on the size and shape of your planter box. For this guide, we'll create a simple rectangular box with the following dimensions:

| Length | Width | Height |
|---|---|---|
| 36" (91 cm) | 18" (46 cm) | 12" (30 cm) |
Cut the Wood Pieces
Using a circular saw, cut the lumber according to the following dimensions:
- 2x2 boards: 4 pieces at 12" (30 cm) for the legs and 4 pieces at 36" (91 cm) for the supports
- 1x6 boards: 2 pieces at 18" (46 cm) for the bottom and 2 pieces at 36" (91 cm) for the long sides
- 1x8 boards: 2 pieces at 12" (30 cm) for the short sides
Assemble the Box Frame
Begin by attaching the long sides (1x6 boards) to the supports (2x2 boards) using 1-1/4" wood screws. Apply wood glue to the joints for added strength. Use clamps to ensure a tight fit while the glue dries.
Next, attach the short sides (1x8 boards) to the frame, creating a rectangular box shape. Again, use wood glue and clamps to secure the joints.

Add the Legs and Reinforcement
Attach the 2x2 legs to the bottom corners of the box, ensuring they are flush with the bottom edge. This will raise your planter off the ground, allowing for better drainage.
For added stability, attach the remaining 2x2 supports to the inside of the box, creating a cross-brace pattern. This will help prevent the box from warping over time.
Attach the Bottom Board
Apply wood glue to the bottom edges of the box frame. Carefully place the 1x6 bottom board inside the frame, ensuring it is flush with the bottom edge. Use 1-1/4" wood screws to attach the bottom board to the frame.
Sand and Finish the Box
Use 120-grit sandpaper to smooth any rough edges or surfaces. Wipe away any dust, and apply your chosen exterior paint or sealant to protect the wood from moisture and pests. Allow the finish to dry completely before planting.
Plant Your Box
Once the finish is dry, fill your DIY wooden box planter with high-quality potting soil. Choose plants that complement your garden design, and enjoy your new outdoor decor! Don't forget to water and maintain your plants regularly to keep them looking their best.
Creating a DIY wooden box planter is a rewarding way to enhance your garden space while honing your woodworking skills. With this step-by-step guide, you're well on your way to transforming your outdoor area into a beautiful, personalized sanctuary. Happy planting!
