Introduction: DIY Wooden Planter

About: Maker in weekends.

i made this DIY planter box with an OSB off-cut that i had laying around.

From time to time i prefer to make small projects, to get rid of my hoard scrap wood.

OSB edges are hidden, by cutting bevel edges, and edge banding the top edges.

This is an easy weekend build, i hope you will like this project.

This will be a prototype to check how much the OSB will hold, to humidity factors.

Supplies

Supplies :

  • -a scrap wood of OSB, or any other board , the one i used here was arround 100 x 25 cm (39.3"x9.8") of 18mm (3/4") OSB
  • glue
  • 12 X corner braces
  • 5 X st4-25 pocket hole screws

Tools used :

  • circular saw
  • drill , with a right angle attachment
  • random orbit sander , you can also use a sandpaper with a block of wood.
  • hand miter saw
  • pocket hole jig

Step 1: Bevel Cut

We will start by doing a 45 degrees bevel cuts on both of our board sides.

Make sure you use a fence to guide the circular saw, to cut straight , and to use a blade with a high number of teeth, since that with yield with a cleaner cut, the blade i used was 48 teeth, and the result were very clean , for a cheap circular saw like the one i used

Step 2: Cross Cut

after that you want to cut the board to 4 equal pieces.

i used my DIY crosscut jig, you can use a speed square, if you are interested in this cross cut jig, you can find the build video on my YouTube channel .

Step 3: Edge Banding for the Top Edges

The bevel edge cut will hide the side edges, we will use the off-cut from cutting the bevel, and make mitered cut pieces in order to edge-band the planter top edges, since those will be visible .

Step 4: Assembly

We will use corner braces in order to join the bevel sides together, this way we will hide the osb edges.

Putting glue will help the joint, in case you had any gap, you can make a paste out of glue and sawdust , and fill the gaps, we will sand it once dry, and the gap should become hidden

I made pocket holes to attach the bottom piece, and i made sure to make a drainage hole with a forstner bit, to allow excess water to escape, to protect you plant roots, and the wood.

Step 5: Sanding and Finishing

Make sure you sand the wood, make sure you don't damage the edges, we need to keep them sharp for the hidden edge look.

Also make sure to put on multiple coat in order to better protect the wood, especially on the inside.

I used boat varnish, this should have better humidity protection.

Step 6: Additional Humidity Protection

I put plastic and glued it with silicon, in order to keep humid soil away from the wood, this is a prototype and time will tell how much this setup will hold.

Also make sure you put some plastic legs, to keep it off the floor, since when the drainage will throw water, it don't get absorbed by the wood,

Step 7: Put Soil and Start Planting

I hope you like this project, i will get back to you hopefully in the future to tell you how this planter will age :)

    Interesting, I too would be interested to see how long this holds up. I've seen a 20 year old shed clad in OSB remain viable, it was kept from ground contact and regularly painted, so I know it's possible. But dirt on the inside is the wild card. Thanks for sharing, creative use for OSB scraps.

    On the inside , the plastic should give some protection, we will wait and see.

    Great project. Personally, I have not had good experiences with particle board outside, but, I've never tried boat varnish. I am very interested in seeing how this stands up. Please consider doing an update post in a year or so. Thanks
