How to Build an Upcycled Planter Box

I am so absolutely thrilled with how this DIY upcycled planter box turned out. I finally used all the fence posts that I scavenged from my neighbor’s trash a couple of year’s ago….sniff

The mix of old weathered wood with fresh rich stained tones is lovely. Plus, as you know, upcycling is my thing 😉

This planter is huge coming in at 7-1/2 feet long. It makes a huge impact as you walk up to my door and I love seeing some color on my porch area.

I pretty much used the same process as I used to make my square planter box

Here is the sad state before the planter box was made. Now this area was fine, since it was simple and just had rocks in it. 

It was obviously zero upkeep and at least looked clean for the time being.  But I wanted more and was ready to take the plunge to add to that area.

How To Make the Upcycled Planter Box

Step 1

Cut four 1” x 4” pieces to 7 1/2’ for the length of the sides. 

Then I cut four to 15” for the other two sides. 

I used a pre-wood conditioner and Minwax’s English Chestnut on the new wood. 

Let dry.

Step 2

Then I cut about 54 fence pickets down to 12”.

Step 3

Using 1/4” scrap wood as spacers I used my air nailer with 1” brad nails and nailed the fence pickets to the top and bottom boards lining up the top and bottom. 

I ended up using my jigsaw to cut a little off the length at the end since it is hard to know exactly how long to cut the pieces since the fence pickets varied a little bit in size.

Step 4

I also found a wider picket for the sides and used one wider picket and two smaller ones. 

If I used three regular sized pickets it was too small and four was too wide for the area so the wider one I had laying around was perfect.

Step 5

Next, I used my Kreg Jig on all four sides and attached it to 2” x 2” cut to 12”.

Step 6

Then I cut some 1×2 furring strips for the top and stained those.

Let them dry.

Step 7

Since I wanted to save money on dirt and certainly didn’t need 12” of it, I used a bunch of scraps I had laying around to make a cleat around the box and then added boards to the top of that. 

That way I had about 6” of dirt to fill.

Step 8

I air stapled black landscaping cloth on the inside.

Step 10

Lastly, I gave the entire piece 3 coats of Spar Varathane to protect it from the elements and help the fence pickets no longer weather.

Step 11

I added dirt mixed with some Osmocote.

I know I have said it before but I just love weathered wood and stained wood together. 

The combination is so pretty.

So I guess I need to restock my weathered fence pickets. 

Who is tearing down a fence I can have? 

I am starting to get the shakes knowing I am all out of weathered wood for projects.

  1. This looks fantastic! It definitely does add some color and interest to your front walkway. I too love the look of the old, weathered wood and the newer stained wood. Great combo!

  2. I love the look of the different wood! Looks so amazing! My hubs is not going to be happy because now I want another box 🙂

  3. Looks great! But what about the concern for the structure weakening from water damage? The untreated picket fence sides (and the flat boards providing the elevated base) strikes me as susceptible to water damage from water held by the soil and landscaping fabric.

  4. Great point. That would definitely be a concern so I gave everything 3 coats of Spar-Varathane to protect from water damage.

  5. Love it, Beckie! Next time I’m at the farm I have to pick up more of this wood to build something like this. Enjoy your weekend 🙂

  6. I love this planter box beckie! do you KNOW how much scrap fence I have laying around? tons! Love the mix of the old and the new. 🙂

  7. Thank you so much for sharing, Kristi. Hope you had a great weekend too!
