How to Make a Large Wood Planter Box

Materials and Tools Needed

Before diving into the construction process, gather the following materials and tools:

Materials

  • Wood: Choose rot-resistant wood like cedar, redwood, or pressure-treated pine. For a large planter box, you’ll need the following dimensions:
  • Four pieces of 2×12 lumber, each 4 feet long (for the sides)
  • Two pieces of 2×12 lumber, each 2 feet long (for the ends)
  • One piece of 1×6 lumber, 4 feet long (for the top trim)
  • Screws: 3-inch galvanized screws for assembly
  • Liner: Landscaping fabric or plastic liner to protect the wood from soil moisture
  • Soil: High-quality potting soil suitable for your plants

Tools

  • Saw: Circular saw or miter saw for cutting wood
  • Drill: Power drill with bits for screws
  • Measuring Tape: To ensure accurate measurements
  • Level: To ensure the planter box is level during assembly
  • Sanding Block: For smoothing rough edges
  • Safety Gear: Safety glasses and gloves

Step-by-Step Instructions

Step 1: Cutting the Wood

Start by cutting your wood pieces to the required lengths. Measure and mark the wood carefully to ensure accuracy. Use a circular saw or miter saw to make clean cuts. You’ll need:

  • Four pieces of 2×12 lumber, each 4 feet long (sides)
  • Two pieces of 2×12 lumber, each 2 feet long (ends)
  • One piece of 1×6 lumber, 4 feet long (top trim)

Step 2: Sanding the Edges

After cutting the wood, sand the edges and surfaces to remove splinters and rough spots. This will not only make the assembly process easier but also ensure a polished final product.

Step 3: Assembling the Sides and Ends

Lay out the four side pieces and two end pieces on a flat surface. Arrange them into a rectangular shape with the ends fitting inside the sides. This will form the basic structure of your planter box.

Using your drill, pre-drill holes at the ends of the side pieces to prevent the wood from splitting. Secure the side pieces to the end pieces using 3-inch galvanized screws. Make sure the corners are square and the edges are flush. Use a level to ensure the sides are even.

Step 4: Attaching the Bottom

Depending on the size of your planter box, you may choose to add a bottom. If you plan to place the planter box on a flat surface, a bottom is not necessary. However, if you want a raised planter box, you’ll need to add a bottom.

Cut additional pieces of wood to fit the bottom of your planter box. Lay them inside the assembled frame and attach them using screws. Make sure to leave small gaps between the bottom boards to allow for drainage.

Step 5: Adding the Top Trim

To give your planter box a finished look, add a top trim using the 1×6 lumber. Measure and cut the trim pieces to fit around the top edge of the planter box. Attach the trim pieces using screws, making sure they are flush with the top edge of the box.

Step 6: Adding a Liner

To protect the wood from soil moisture and extend the life of your planter box, add a liner. You can use landscaping fabric or plastic liner. Cut the liner to fit inside the planter box, covering the bottom and sides. Secure the liner in place with staples or small nails.

Step 7: Filling with Soil

Now that your planter box is assembled and lined, it’s time to fill it with soil. Choose a high-quality potting soil that is suitable for the plants you intend to grow. Fill the planter box with soil, leaving a few inches of space at the top for watering.

Step 8: Planting

With the planter box filled with soil, you can now plant your chosen flowers, vegetables, or herbs. Arrange the plants according to their spacing requirements and water them thoroughly after planting.

Tips for Success

  1. Choose the Right Wood: Opt for rot-resistant wood like cedar or redwood to ensure the longevity of your planter box.
  2. Pre-Drill Holes: Always pre-drill holes before inserting screws to prevent the wood from splitting.
  3. Use a Level: Ensure the sides and bottom of the planter box are level during assembly for a professional look.
  4. Add Drainage Holes: If you include a bottom, make sure to leave gaps between the boards or drill drainage holes to prevent waterlogging.
  5. Protect the Wood: Applying a wood sealer or stain can provide additional protection against the elements.
