DIY Square Concrete Planter

Create your own square concrete planter using patio pavers that’s perfect for winter and many seasons to come!

What to Buy

For one planter, cut (4) 2x2s at 14 inches long and (6) at 12 inches. If you’re making 2 planters, you can get away with purchasing (3) 2x2s. You won’t need 2 full pieces per planter. Just FYI!

Drill Pocket Holes

There are several ways to assemble your square concrete planter. The method I chose is creating hidden fasteners with a pocket hole jig. I’ve used this before to build a bathroom vanity and dollhouse nightstands. It’s super easy once you own a jig!

Drill pocket holes on the end of each of your 12-inch base pieces.

Attach 2 legs to one base piece. Then repeat. Join the two together with 2 more base pieces. Lastly, attach the remaining base pieces in the middle to create a support for a paver on the bottom.

You could also screw the legs onto the base through the outside of the leg with 2-1/2 inch exterior screws. Though the fasteners won’t be hidden this way.

Glue Pavers in Place

After your 2×2 base is assembled, you’re ready to glue the pavers in it to create your square concrete planter. Start by applying adhesive to the 2 bottom pieces of wood and lay one paver on top, making sure its centered.

Next, using a masonry bit, drill a hole in the middle of the paver for drainage. 1/4 inch is large enough but you could also use a smaller bit and drill 2 holes if that’s what you have on hand!

Then you’re ready to add the sides! Apply construction adhesive to the sides and bottom edge of each opening of your wood frame. Squeeze a little onto the edge of the bottom paver too. Carefully set a paver on its edge into place. You’ll likely need to pull the wood legs apart to fit the paver. But that just means a nice tight fit!

If the tops of the wood legs aren’t staying tight to your pavers after everything is in place, use a large clamp or ratchet strap to keep it tight while the adhesive sets up.

Once the adhesive is dried, you’re ready to add potting soil and pretty plants to your square concrete planter! I opted for a winter look with a tall cypress in the middle and a few Dusty Millers around the bottom.
