Depending on your budget and the wood available in your area, you'll need to select the wood you will use for this project. While cedar is ideal, Douglass fir is a great alternative and about half the price of cedar.

Assemble the garden box on an even surface using the 10' lengths on the sides and the 5' lengths on the ends. Stack the wood four pieces high, staggering the corners as you go.

Once you have your four layers of wood lined up, give your garden box a final check to make sure all the pieces are in place.

Starting in the corner of your garden box, use a 7/8" drill bit to drill through all four pieces of wood. Be sure and keep your drill bit nice and straight as you drill through the wood.

Step 6: Vacuum Wood Shavings as You Drill

It is helpful to have someone sucking up the wood shavings with a vacuum as you drill the holes into the wood. If you don't vacuum the wood shavings as you go, the drill bit could get stick in the hole you are drilling and become difficult to remove.
