How To Build a Wood Planter Box

5 Materials
5 Hours

Ever seen those high-end planter boxes that look super high end? Have you priced them? They LITERALLY cost a fortune---easily over $100.

No worries.

Why buy one when you can make your own?

Here's a simple tutorial to make your own for a fraction of the price.

Here are the wood planters that we built for the front of the house. All you need to get started is plywood and simple pine trim.

Step 1: Nail sides

Start by nailing two of the pieces of 1/2″ plywood cut to 16″ x 22″ together.

Line up the two of the pieces together at a right angle and nail together.

Repeat with each of the plywood pieces until you have a box.

2. Nail bottom

Attach the bottom piece of 1/2″ plywood cut to 16 1/2″ x 16″ 1/2″to your nailed-together four sides.

The edge of the bottom of the planter should line up with the sides of the planter.

Nail bottom piece to the box.

3. Sand any rough edges

Sand off any of the rough edges and you are ready for the trim.

4. Add trim

Attach 2 pieces of 1″ x 3″ x 17″ pine to the top of the box.

Line them up at a right angle, level with the top of the box and nail in place.

Repeat with the other pieces of pine until you have trim on all four sides of the box.

Quick tip: Sometimes your molding pieces may not match exactly.

They might look like this.

No worries.

That’s what caulk and paint are for.

5. Add bottom trim

Repeat the same steps with the bottom molding pieces of 1″ x 3″ x 17″ pine.

Nail them level with the bottom of the planter.

Attach each piece at a right angle.

5. Prep the planter for painting

Sand off any rough edges.

Caulk the gaps.

Now the planter is ready to prime and paint.

6. Paint

Here's the finished planter that we painted white.

We also added raised monogram letters as well as curtain finials for feet. You can see how we added the letters here.

I’m so happy with how the planters turned out.

The main cost for the planters was the wood. I already had the paint and primer.

Total receipt from the home improvement store?


So much better than a $100.00.

And way cuter, too.

    How will you keep the wood from rotting/warping from watering, especially inside where it won't dry off like wood siding?

    • Cindy
      on Aug 15, 2019

      You can put a potted plant inside instead of filling the whole thing with soil and then a plant. Easy to water.

    It looks as if you used regular plywood instead of treated. Did you use some deck paint to protect these from water?

    • Thistlewood

      I did use regular plywood! The inside is painted and the planters are on a covered porch---so water isn't an issue.

    One other question...did you drill holes in the bottom where water can escape?

    • Thistlewood
      on Aug 22, 2019

      Yes! There are holes in the bottom for drainage. I just added a potted plant---I didn't plant directly into the planter!
