Materials Needed
Before you begin, gather all the necessary materials. Here’s a list of items you’ll need to build your own large planter box:
- Cedar or Pressure-treated Lumber (2x4s and 1x6s)
- Exterior Wood Screws
- Wood Glue
- Drill and Drill Bits
- Saw (Miter Saw or Hand Saw)
- Clamps
- Measuring Tape
- Pencil
- Level
9 Step-by-step Guidelines on How to Make a Large Planter Box
Step 1: Prepare the Lumber
Start by measuring and cutting your lumber to the required dimensions for the planter box. Using your measuring tape, mark the lengths you’ll need for the frame and sides of the box. Commonly, you’ll need four equal pieces for the longer sides, four shorter pieces for the ends, and additional planks for the base. Use a saw, such as a miter saw or hand saw, to make precise cuts.
After cutting, sand the edges of the wood to ensure smooth surfaces and avoid splinters during assembly. This step is crucial for creating a clean and professional-looking planter box.
Step 2: Create the Frame
Using your shorter pieces of wood, create a frame by attaching them to the longer pieces at right angles. Use exterior wood screws and wood glue to secure the joints. Pre-drill holes before inserting the screws for added strength and to prevent splitting. Repeat this process until you have four connected frames.
You can also add additional support to the corners by using angled brackets or reinforcing blocks for added stability.
Step 3: Assemble the Sides
Attach the sides of your planter box by screwing them into the frame you created in step 2. Start with one end, then attach the longer side pieces, followed by another end piece, and finally, attach the remaining long side pieces. Use wood glue to strengthen joints and achieve a sturdy structure.
It’s important to ensure that the sides are all flush with each other and the frame is level to avoid any gaps or unevenness in your planter box.
Step 4: Add Drainage Holes
To prevent water from pooling in your planter box, drill drainage holes in the bottom of the frame. Use a drill bit slightly larger than the screw to create adequate drainage.
You can also add a layer of gravel or mesh at the base before adding soil to further improve drainage.
Step 5: Create a Base
To create the base of your planter box, measure and cut planks to fit snugly within the bottom frame. Lay the planks side by side, ensuring there are minimal gaps between them to provide strong support for the soil and plants. Secure the base planks to the frame using exterior wood screws, spacing the screws evenly for stability.
For added durability, consider leaving small gaps (approximately 1/4 inch) between the planks to allow excess water to drain more effectively. If preferred, you can line the base with landscape fabric or mesh before adding soil to prevent it from washing out while maintaining proper drainage. This step ensures that your planter box is sturdy and ready to support the weight of the soil and plants.
Step 6: Adding Finishing Touches
Once the structure of the planter box is complete, it’s time to add the finishing touches to enhance its durability and appearance. Start by sanding down any rough edges or uneven surfaces to create a smooth finish. This step not only improves the aesthetics but also minimizes the chances of splinters or injuries.
Next, apply an exterior wood stain or waterproof sealant to protect the wood from weather elements, such as moisture and sunlight. Choose a stain or sealant that suits your desired look, whether you prefer a natural wood appearance or a variety of color options. Be sure to apply at least two coats, allowing the product to dry completely between applications for maximum protection.
If you’d like, you can also add decorative features like trim, handles, or painted designs for a personalized touch. Finally, inspect the planter box for any loose screws or weak areas and make any necessary adjustments. Once this step is complete, your planter box is ready to be filled with soil and plants!
Step 7: Filling the Planter Box
Fill your planter box with a high-quality potting soil mix, leaving about an inch of space at the top for watering. This type of soil provides necessary nutrients and drainage for healthy plant growth. If you’re planning to grow vegetables or herbs, consider using a mix specifically designed for edible plants.
Ensure that the soil is evenly distributed and level in the planter box before adding your desired plants or seeds. You can also add mulch on top of the soil to retain moisture and suppress weed growth.
Step 8: Maintenance
To keep your planter box looking its best, regular maintenance is essential. Water your plants as needed and remove any dead or dying vegetation to promote healthy growth. Depending on the type of wood used, you may also need to reapply a waterproof sealant every few years to protect against weather damage.
You can also periodically check for any signs of rotting or damage to the structure and make necessary repairs. With proper care, your planter box can last for many years to come.
