A wooden planter box is a fantastic addition to any garden or outdoor space. Not only does it provide a stylish and customizable way to display your plants, but it also allows for better organization and efficient use of space.
Whether you’re an experienced DIY enthusiast or a beginner looking for a simple, rewarding project, building a wooden planter box is an excellent way to enhance your gardening experience.
This guide on how to make a wooden planter box will walk you through the steps to create your very own planter box, using basic tools and materials. Creating wooden planter boxes DIY is an excellent way to add a rustic charm to your garden while giving you a hands-on project to showcase your green thumb.
Why Choose Wood?
Wood is an ideal material for building a planter box due to its natural charm, durability, and versatility. Unlike plastic or metal alternatives, wood blends seamlessly into the garden environment, creating a warm and rustic aesthetic. Additionally, wood is readily available and easy to work with, making it perfect for DIY projects.
Properly treated or naturally rot-resistant woods, like cedar or redwood, can withstand the elements, ensuring your planter box remains functional and attractive for years to come. With wood, you also have the freedom to customize the size, shape, and finish to suit your personal style and gardening needs.
Needed Tools and Materials
Tools:
Measuring Tape:
A measuring tape is essential for precise measurements and ensuring all pieces of wood are cut to the appropriate size.
Saw:
You will need a saw to cut the wooden boards to your desired dimensions. A handsaw or circular saw can do the job, but if you have access to a table saw or miter saw, cutting will be faster and more accurate.
Drill:
A drill is necessary for making holes in the wood for screws and drainage. If you don’t have a drill, you can use a hammer and nails instead.
Sandpaper:
Sandpaper is necessary to smooth out rough edges and create a polished finish. Depending on your preference, you can choose from different grits of sandpaper for a smoother or rougher finish.
Screwdriver:
A screwdriver is needed to drive in the screws and secure the pieces of wood together. An electric screwdriver can save time and effort, but a manual screwdriver will also work.
Materials:
Wood:
Choose a type of wood that is suitable for outdoor use and fits your budget. Cedar, redwood, and pressure-treated pine are popular choices, but any type of sturdy wood will do.
Screws:
Use rust-resistant screws with the appropriate length for your chosen wood thickness. For example, if your wooden boards are 1 inch thick, you will need screws at least 1 inch long.
Waterproof Wood Glue:
To reinforce the structure of your planter box, waterproof wood glue can be used in addition to screws. This will ensure that your planter box is sturdy and long-lasting.
Lining Material:
To protect the wood from soil and moisture, you will need a lining material such as landscape fabric or plastic sheeting. This will also help with drainage and prevent water from seeping out of the bottom of the planter box.
7 Step-by-step Instructions on How to Make a Wooden Planter Box
Step 1: Cut the Wood
Start by measuring and marking the wooden boards according to the desired dimensions of your planter box. Typically, you will need four pieces for the sides and one piece for the base.
Use a measuring tape to ensure accuracy, and mark the cutting lines with a pencil or chalk. Once marked, carefully cut the wood using a handsaw, circular saw, or table saw, depending on the tools available. Remember to wear safety gear, such as gloves and goggles, while cutting.
After cutting, use sandpaper to smooth the edges, removing any splinters or rough spots. This will make the assembly process easier and help create a polished, professional look for your planter box.
Step 2: Make Drainage Holes
Proper drainage is essential to prevent water from collecting at the bottom of your planter box, which could lead to root rot and damage to your plants.
To create drainage holes, take the wooden base piece of your planter box and mark evenly spaced points where the holes will be drilled. A good rule of thumb is to make 4-6 small holes, depending on the size of the base, to ensure adequate drainage.
Using a drill with an appropriately sized drill bit, carefully drill holes at the marked points. Be sure to work on a stable surface and apply steady pressure while drilling to avoid splitting the wood.
If you prefer, you can sand the edges of the holes to remove any rough or splintered wood, ensuring a smooth and clean finish. Once the drainage holes are complete, your base is ready to be attached to the sides in the next step.
Step 3: Assemble the Sides
Take two of the wooden boards you cut in step 1 and lay them parallel to each other on a flat surface. Place the remaining two boards perpendicular to the first two, forming a rectangle shape.
Check for accuracy using a measuring tape or square tool before moving on. Once aligned, apply a thin layer of waterproof wood glue along one edge of the longer sides and attach them to the shorter sides. Secure with screws at each corner, making sure they are flush with the edges. Repeat this process until all four sides are attached together.
Note: For added sturdiness, you can also use corner brackets or L-brackets to reinforce the corners of your planter box.
Step 4: Attach the Base
Now it’s time to attach the base (with drainage holes) to the sides of your planter box. Apply a thin layer of wood glue along the edges of the base, and carefully position it inside the assembled sides.
Use screws to secure the base to each side, making sure it is level and flush with the edges. This will ensure a stable and balanced planter box.
But, before attaching the base, you may want to consider adding a lining material to protect the wood and improve drainage. Simply cut a piece of landscape fabric or plastic sheeting to fit inside the planter box and secure it along the edges with staples or glue.
Step 5: Sand and Finish
Once the planter box has been fully assembled, take the time to sand down the entire surface to ensure it is smooth and free of any rough edges or splinters.
This step is important not only for aesthetics but also for safety, as it prevents any risk of injury while handling the planter box. Use fine-grit sandpaper for a polished finish, working in even strokes along the grain of the wood.
After sanding, apply a finish to protect the wood from outdoor elements. You can choose a waterproof wood sealant, an outdoor wood stain, or a combination of both depending on your preference and the type of wood used.
Use a clean brush or cloth to evenly apply the finish, and allow it to dry as per the manufacturer’s instructions. Adding this layer of protection will ensure your planter box remains durable and visually appealing for years to come.
Step 6: Add Legs (Optional)
If you want to elevate your planter box, you can add legs or stands. This will not only create a more visually appealing design but also make it easier to maintain and prevent any damage to the bottom of the box.
You can use pre-made wooden or metal legs, or construct your own using scrap wood from the initial cutting process. Simply attach them to the base using screws and wood glue, making sure they are evenly spaced for balance.
Step 7: Fill with Soil and Plants
Now that your planter box is fully constructed and ready for use, it’s time to add soil and plants. Begin by ensuring the lining material inside the planter box is properly laid out and secured, as this will protect the wood and aid in drainage.
Next, add a few inches of coarse gravel or small pebbles at the bottom of the planter. This layer will further improve drainage and prevent water from pooling at the roots of your plants.
Once the base layer is complete, fill the planter box with high-quality potting soil. Make sure to select soil that is appropriate for the type of plants you intend to grow.
Spread the soil evenly and leave about 1-2 inches of space below the top edge of the planter to prevent soil from spilling over the sides. Finally, carefully plant your desired plants and give them a good watering.
Congratulations, you have now successfully built your own planter box! With proper care and maintenance, it will provide a beautiful home for your plants and add a touch of natural beauty to any outdoor or indoor space. Experiment with different sizes, shapes, and finishes to create unique planter boxes that reflect your personal style. Happy gardening!
