✂️ Step-by-Step Guide to Building Your Planter Box

1. Measure and Cut Your Wood

Decide on the dimensions of your planter box. For a simple rectangular box, a common size is 24″ long, 12″ wide, and 12″ high. Using your measurements, mark and cut the cedar boards accordingly:

- (2) Side panels: 24″ x 12″

- (2) End panels: 12″ x 12″

- (1) Bottom panel: 24″ x 12″The Home Depot Canada

Cedar is recommended for its natural resistance to rot and insects.

2. Assemble the Frame

- Apply wood glue to the edges of the end panels.

- Attach the end panels to the inside edges of the side panels to form a rectangle.

- Clamp the pieces together and drill pilot holes to prevent splitting.

- Secure the panels with 1 1/4″ exterior wood screws.

3. Attach the Bottom Panel

- Place the bottom panel inside the frame, ensuring it fits snugly.

- Drill pilot holes and secure the bottom panel with screws through the side and end panels.

4. Drill Drainage Holes

To prevent water accumulation, drill several 1/2″ holes evenly spaced across the bottom panel. This ensures proper drainage and promotes healthy root growth.

5. Sand the Planter Box

Use sandpaper or a power sander to smooth all surfaces and edges. This not only enhances the appearance but also removes any splinters or rough spots.

6. Apply Finish

Protect your planter box from the elements by applying a wood sealer, exterior paint, or stain. Ensure all surfaces, including the interior, are coated. Allow the finish to dry completely according to the manufacturer’s instructions.

7. Line with Landscape Fabric

Cut a piece of landscape fabric to fit the interior of the planter box. Staple or tack it in place. This helps retain soil while allowing water to drain.

8. Add Soil and Plants

Fill your planter box with high-quality potting soil, leaving about an inch of space from the top. Plant your chosen flowers, herbs, or vegetables, and water them thoroughly.

🌸 Customisation Ideas

Personalise your planter box to match your style and needs:

- Add Legs: Elevate your planter by attaching legs, making it easier to access and adding visual interest.

- Paint Designs: Use stencils or freehand painting to add patterns or motifs.

- Attach Trellises: Support climbing plants by adding a trellis to one side.

- Incorporate Storage: Design a double-decker planter with storage space for gardening tools underneath.

🧼 Maintenance Tips

To ensure your wooden planter box lasts for years:

- Regularly Check for Rot: Inspect the wood for signs of decay, especially after rainy seasons.

- Reapply Finish: Depending on exposure, reapply paint or sealant every 1-2 years.

- Clean Seasonally: Remove old plants and soil annually, clean the interior, and replace with fresh soil.
