Modern Planter




About: Discover woodworking, concrete, LEDs, home decor and DIY projects you'll love.

In this Instrucatable, I am building a simple, yet modern, planter box.

Materials needed:

(1) 10-feet Cedar lumber

(1) Weed barrier

(1) Bag or river rocks

(3) Plants of choice (I used White African Iris)

(1) Bag of pot soil

- Outdoor Screws

- Outdoor wood glue

Step 1: Cutting the Wood

Feel free to make this box as big or small as you like. The dimensions are below for this box.

After all the cutting, you should end with 9 pieces. (See below.)

The type of wood used for the project is Cedar.

Wood Dimensions:

(3) 7x30 inches = 2 long sides and bottoms

(2) 6 1/8 inches X 7 1/8 inches = 2 short sides

(4) 2 x 3 feet

Step 2: ​Assembling

When wood searching, try finding a good and flat lumber. I grabbed one that was a bit warped, and it was challenging to assemble. Using clamps helped hold the box together.

Since water will be constantly added, use screws that are made for outside application, such as those for wood fences and decks.

Adding wood glue would also help with the strength of the box.

Step 3: Prepping and Finishing

I applied an interior/exterior wood filler to cover the screw heads.

Sand the box down until smooth using 220-grit sandpaper.

Then apply the paint of choice. I used "Pure white High Gloss Latex."

Step 4: Attaching the Feet

Use an exterior wood glue for this application. You will also need to screw the feet on as well.

I used a combination square to keep the feet the same distance away from the edge.

Since I used wood glue only, masking tape was added to hold the feet in place as I put weight to hold it down.

Step 5: Adding Soil

Drill out two holes for drainage.

Install a weed barrier. This will also prevent the soil from falling through the drain holes.

I used garden soil, but I was informed that pot soil is better for this application.

Place enough soil to cover the entire bottom.

Step 6: Adding the Plants

Remove the plants from the pot and place in the box. Lightly loosen up the roots, but not too much.

Fold the weed barrier over as shown in the last picture. Then move on to the next step.

Step 7: Adding Rocks

Place the river rocks on top the of the weed barrier. Then do this all the way around, using the rocks to hide the soil and the weed barrier. Then, add water and you are done!

Looks great! Congratulations. Nice simple lines. Cedar is the ideal wood here as it avoids fungus attacks more than other woods. So seeing as it will be exposed to moisture you've picked the perfect wood.
