Spring has officially sprung! It’s time to start thinking about what you’d like to plant in your garden, in your flower beds, and around your home this year.

A DIY planter box is a perfect project to tackle during spring time. Today we’ll show you how to make your own cedar planter box on wheels.

This planter box is versatile – use it as a flower box, a herb garden, or to grow your favorite vegetables. Wheel it around your porch or patio to give your plants the right light, or to easily switch up your spring decor. And since it’s cedar, it will be sturdy and should last for years to come. Let’s get started!

Cedar Planter Box DIY:

This planter box DIY is an ideal project for a first-time DIYer. It’s fairly easy to put together, and everything is a straight cut–no fancy angles.

First, you will need to gather a few supplies. I chose to use cedar wood for this project because it is very resistant to rotting. My planter boxes will look great for years to come with little upkeep.

Cedar is rather expensive though! You could use regular pine boards instead. Just remember if you do, you’ll need to paint or stain them to protect them from the elements.

You will need:

  • Four pieces of 1×6 cedar boards, 8 feet long
  • One piece of  2×4 cedar board, 6 feet long
  • 1-inch brad nails
  • 2-inch brad nails
  • 4 L brackets
  • 4 wheels
  • 1 1/4 inch wood screws
  • wood glue


  • table saw
  • miter saw
  • drill
  • nail gun
  • rubber mallet

For reference, the finished size of this planter box will be 20 ½ inches tall, and it will be a 19 ½ inch square box.

Remember safety always comes first. Please use eye protection and earplugs, and follow all safety precautions when using power tools. They can be dangerous!

Step 1

Cut your cedar boards to size to create the sides of your planter. To do this, cut the 1×6 boards into twelve 16 inch pieces. You’ll need three of these pieces for each side.

Step 2

Using wood glue, attach three of your 16-inch pieces together. You should now have four 16 by 18-inch pieces. These will be the sides of your planter box.

Step 3

Next, you will cut eight trim pieces using a 1×6 board cut into 3/4 inch strips. Each trim piece will need to measure 16 ½ inches long.

Using a nail gun and one-inch brad nails, attach a trim piece to the top and bottom of each side. Don’t forget to add some wood glue between your trim piece and side boards before you nail your side together. The wood glue is what actually holds this planter box together. The nails are just holding everything in place until the glue dries.

Step 5

Next, put it all together! Assemble the four sides using wood glue, the nail gun, and two-inch brad nails. You can use some scrap wood underneath to hold your planter up as you attach the sides.

Step 6

To make your planter a little more sturdy, attach L brackets in each corner using the supplied screws about ¾ of an inch down on the inside of your planter.

Step 7

Next, we’ll add support beams to the bottom of your planter. Dirt and water are both super heavy, so you wouldn’t want to fill the entire planter with dirt.

We chose to go about seven inches deep with our support braces. You’ll need two of these support braces and to make them, cut a piece of the 1×6 cedar board into 1/2 inch strips and then cut them into 16 ¼-inch long pieces. Using wood screws, attach these two brace pieces to opposite sides of the inside of your planter box.

Step 8

To create the bottom of your planter box, cut one of your 1×6 cedar board into three 16 ¼ inch pieces. Place these pieces inside the bottom of your planter. The fit will be snug. If desired, you could nail the boards in place using a nail gun. We opted just to set ours inside.

Do not wood glue these pieces together like you did the other pieces. These unsealed seams will give your planter plenty of drainage later on when you begin to water your plants.

*Step 9

If desired, you can add wheels to your planter box to make it easier to move around your porch or patio. So the last step is to add your wheels to the bottom of your planter. To do this drill a hole in the middle of each leg with your drill.

Then with a mallet put your wheel inserts into each leg.

Flip it over and enjoy your new DIY planter box!

Before you fill your new planter box with your favorite greenery, be sure to wait 24 hours for the wood glue to dry completely. Then add your dirt and your favorite flowers, or try planting your favorite berries or veggies!
