Building an outdoor plant box with a slanted bottom is a practical solution to improve drainage and prevent waterlogging, ensuring healthier plants. Here’s a step-by-step guide to creating your own sturdy and functional wooden planter.

Materials Needed:

- Pressure-treated lumber or cedar boards

- Measuring tape and pencil

- Saw (circular or hand saw)

- Drill and screws

- Waterproof wood glue

- Level

- Sandpaper

- Waterproof sealant (optional)

Step 1: Measure and Cut the Wood

Determine the desired size of your plant box. Cut the front, back, and side panels from the lumber. For the slanted bottom, cut two side panels at a slight angle (about 5-10 degrees) to create a downward slope toward the front.

Step 2: Assemble the Frame

Attach the side panels to the front and back panels using screws and waterproof wood glue for extra stability. Ensure the angled side panels are positioned correctly to create the slope.

Step 3: Install the Slanted Bottom

Cut the base panel to fit inside the frame. Place it on the angled sides, ensuring it slopes toward the front for drainage. Secure it with screws and reinforce with glue.

Step 4: Add Drainage Holes

Drill small holes along the lower edge of the front panel to allow excess water to escape. Sand any rough edges for a smooth finish.

Step 5: Seal and Protect (Optional)

Apply a waterproof sealant to prolong the life of your plant box, especially if using untreated wood.

Step 6: Fill and Plant

Add a layer of gravel or small rocks at the bottom for additional drainage, then fill with soil and your chosen plants.

This DIY outdoor plant box with a slanted bottom is perfect for gardens, patios, or balconies, combining functionality with a rustic charm. Happy planting!
