How to Build a Cedar Planter Box

When spring hits, it’s time to get those outdoor plants going so let WWGOA show you how to build a cedar planter box. It’s a lot of fun to plant flowers or veggies (and it’s a great thing to do with kids) and it’s even more fun when you’re putting them in a planter that you built.


This planter is made completely out of cedar 1x12s. To give the planter its compound angle look everything is cut at 10-degrees. This looks complex, but can be easily done on the miter saw or table saw. The front and back are 28” long at the long point, and the ends at 14-½” long. A 10’ long board will make all of the parts required for the planter. The ends of the front and back are rabbeted. The bottom is cut to fit and gets ¼” holes drilled through it for drainage. Pay careful attention to the video and the way the parts are cut to make sure you can get all of your pieces out of the 10’ board.

Glue Choice

The best glue for this project is Titebond III. Once you fill the planter with soil and get plants going, you’re going to have a constantly damp environment. That’s what makes Titebond III a great choice. It’s waterproof, so it’ll tolerate the moisture, no problem.

    Shouldn’t the box be lined with some sort of landscape fabric to prevent the soil from falling out the drain holes?

      Hi Michael. It works well without that, but it wouldn’t hurt anything if you wanted to line yours.

    Is cedar pretty resistant to the elements? Can this box be left out in the open (not under cover) or should some kind of finish be applied for uncovered outdoor locations?

      Hi Ryan. Yes, cedar is resistant to elements. You can apply a deck stain to extend the useful life and keep it looking fresh, but you can get man years out of it without applying a finish.
