Outdoor Wood Planter Box Ideas and Designs for Beginners

If you're new to woodworking and want to create a beautiful outdoor space, a wooden planter box is a great place to start. You can choose from a variety of designs, such as the Modern Rectangular Planter Box, which is perfect for small gardens.

A key consideration when building a planter box is the type of wood you use. Western Red Cedar is a popular choice because it's naturally resistant to rot and insects, making it ideal for outdoor use.

You can also consider the size of your planter box, such as the Small Square Planter Box, which is perfect for a small patio or balcony.

When it comes to building an outdoor wood planter box, the right materials are essential. To start, you'll need some basic supplies, including rough-sawn cedar 2x4s for the frame, which are a cost-effective option and can be sanded to a smooth finish.

You can also use cedar fence pickets for the sides, which are a great option because they're affordable and can be easily sanded to reveal a clean surface. Alternatively, you could use pressure-treated lumber or other outdoor-friendly woods like Redwood or Ipe.

To attach everything together, you'll need some exterior screws, wood glue, and a drill. A miter saw and circular saw will also come in handy for making precise cuts.

Here are some key materials to keep in mind:

When working with wood, it's essential to choose the right type for your project. Cedar is a popular choice for outdoor projects due to its rot and weather-resistant properties.

You can use cedar, pressure-treated lumber, or other outdoor-friendly woods like Redwood or Ipe. However, cedar is generally a great choice for outdoor projects like this.

To keep costs down, consider using rough-sawn cedar 2x4s for the frame. These boards have not been sanded and are straighter, making them ideal for this project.

Here are some specific supplies you'll need:

Keep in mind that you can also use 2x2 lumber, but it may not be as sturdy as 2x4s.

If you're looking to create a tiered planter using cedar wood, you're in luck because it's a great choice for outdoor projects. Cedar is rot and weather-resistant, making it an excellent option for withstanding the elements.

For the frame, you can use rough-sawn cedar 2x4s, which are cost-effective and can be sanded to a smooth finish. To get the best results, choose boards with as little twist and bend as possible, and use a sander to work your way up from 80-100 grit to at least 180 grit.

For the slats on the sides, you can use 3/4" cedar fence pickets, which are usually rough-looking but can be sanded to reveal a clean and smooth surface. To make the process easier, use an orbital sander to achieve a high-grit finish.

Here are some other options to consider for your cedar tiered planter:

Remember to use untreated wood to avoid harming your plants with chemicals from treated wood.

We used Cedar, which is rot and weather-resistant, for our outdoor wood planter box.

To keep costs down, we chose "rough-sawn" cedar 2x4s for the frame. This means none of the surfaces have been sanded, so it's essential to choose boards with minimal twist and bend.

Start by selecting boards with as little twist and bend as possible from the store. This will make the project much easier.

To get a beautiful cedar surface, use a sander to work your way up from 80-100 grit to at least 180 grit. This should go relatively quickly if you start with a low grit.

For the slats on the sides, use 3/4" cedar fence pickets, which can be sanded to 180 grit using an orbital sander.

Here are the approximate sizes for the frame parts and slats:

Assembling and constructing your outdoor wood planter box requires some careful planning and precision. To start, you'll need to pre-assemble the long sides by attaching four long slats to two legs, making sure the back of the slats lines up flush with the back of the legs for a 3/4" reveal on the front.

Using a piece of wood to shim the slats is a great trick to help you line up the back edges of both. This ensures a sturdy and even base for your planter box. You can attach the slats to the legs with 1.25" exterior screws, starting with the top and working down all four slats.

Once you've completed one long side, you can repeat the process on the opposite side, making sure everything is square and secure.

As you start to see your raised planter box take shape, it's time to assemble all four sides. To begin, position the second pre-assembled long side upside down on a table so that the side slats line up with the leg in the appropriate place. Ensure everything is nice and square.

You'll want to use pocket screws to attach all eight slats to the second side. This will give you a solid foundation for your planter box. As you work, use a square to ensure your side slats go on squarely and perpendicular to the long side.

To attach the slats, start at the bottom and work your way up all four slats. Use a piece of wood to line up the back flush with the legs. Then, attach the side slats with the pocket screws. Repeat this process on both sides so that all eight side slats are attached to one of the long sides.

Here's a summary of the assembly process:

By following these steps, you'll have all four sides of your raised planter box assembled and ready for the next stage of construction.

The four bottom rails are used to hold up the bottom slats and ultimately the weight of the dirt and everything inside the planter.

They get attached at an angle so water drains towards the center. There are two on each side.

Each bottom rail is raised 1” from the bottom and positioned centered between the batten and the side slats.

Attach each piece with wood glue and five screws.

The bottom slats support the weight of the soil and dirt inside the planter, and they're attached with wood glue and one screw on each side. This is a great opportunity to use scrap pieces you have on hand, just make sure to cover the majority of the bottom.

To attach the bottom slats, you'll want to ensure you leave a ~1/4” gap between each board, which gives you the option to add more drainage in the future if necessary.

Here are the approximate sizes for the bottom slats:

The bottom slats are attached at an angle, so water drains towards the center, and they're positioned centered between the batten and the side slats.

To protect the wood and give it a clean look, we applied a finish to both the frame and the slats.

We recommend painting the frame pieces with two coats of exterior dark gray/black latex paint, and a third coat on the end-grain for extra protection against water.

A roller is a great tool to use when painting to avoid brush strokes.

For the slats, we used a Spar Varnish to retain their natural color and look, and applied three coats, letting each dry completely before applying the next.
