Wooden planter boxes are a great way to incorporate some greenery into your space. You don’t need a sweeping garden for them—an empty balcony or a wistful windowsill is enough. You can use them as a blooming calendar too. Think petunias in spring, bougainvillaeas in summer, dahlias in autumn, and cold-hardy alyssums in winter.

You can use cypress or cedar boards if you plan to make your own. Alternatively, you can turn a wicker basket, an old drawer, or even a scrap pallet into a creative planter box.

Read on for a step-by-step guide to making your own wooden planter box. We’ll also show you how to build a planter box the easy way and give you some tips on how to make your planter box more durable.

How to make a wooden planter box step by step

To make a planter box out of wood, first, gather all your tools. Then choose the wood you want to work with—teak, cedar, and cypress are some good options.

Next, size and cut the wooden boards and glue the pieces. You may also want to secure the joints with screws.

Once ready, add the finishing touches. Sand any rough edges, prime and paint the outside, or polish it. Finally, fill the planter box with potting soil and plant away.

Let’s take a closer look at each of these steps:

Step 1 – Gather all materials and tools

For your planter box, you’ll need a few basic tools and materials. These include:

Step 2 – Choose the wood

You want your wooden planter box to look classy while also being durable. Choose the wood wisely and make sure it’s resistant to rot and insects.

Cedar and redwood and widely available. They’re also lightweight and crack resistant. Cypress and teak are other options to consider.

Tip: Avoid softwoods like pine and spruce. These are vulnerable to decay.

Step 3 – Size and cut the boards

Once you’ve chosen the right wood for your planter, it’s time to size it. Choose how big (or small) you want it to be. If you’re unsure, think of where you’ll place the planter box.

You can then cut the boards using a saw. When finished, you should have four pieces for the sides and one for the bottom.

Step 4 – Attach the pieces

Time to assemble and glue the pieces. Begin by placing the bottom piece down. Apply strong wood glue around the edges and stick the sides to it.

Once assembled, secure the box with a clamp. While the glue dries, drill screws into all the joints for extra strength. You may also want to drill a drainage hole.

Step 5 – Sand any rough edges

Sanding will give your box a finished look and also save your gardening fingers from potential splinters in the future. Use a sander or sandpaper and run it along the outer surfaces of the box.

Step 6 – Prime, paint, or polish

Priming and painting your box will make it sun and rain-ready. You can choose the colour to match your backyard or home decor.

You can also polish your planter box to bring out the wood’s natural colour but this isn’t ideal if you plan to leave it outdoors.

Step 7 – Plant away

Time to add plants to your box. Before you begin planting, line the box with a plastic sheet to protect the wood. Then add a thin layer of gravel and fill the rest with potting soil.

You can plant seasonal flowers, perennials, seeds, and even vegetables and herbs in your box. Don’t forget to water and occasionally prune them.

Do you have any vintage drinks crates, useless drawers, wood baskets, or old toolboxes? Instead of throwing them away, you can repurpose them into attractive planter boxes.

You may need to clean the container before you can use it. Scrape off any peeling paint, sand the surface, and remove any rusty nails.

Step 3 – Paint or stain it

To extend the life of your wooden container, you’ll have to prime and paint it. You can also use a wood stain for a rustic look.

Step 4 – Fill it with plants

Once ready, line the box, fill it with soil, and begin planting. Choose the plants according to the size of your box. You can fill it with flowering annuals, succulents, vines, and even herbs.
