I love gardening and I love making things from wood.
This is how I make my simple raised beds. You just need wood, a chop saw, drill, and screws.
Step 1: Cut and Lay Out Your Pieces
I bought (2) 2 in. x 6 in. x 12 ft. #2 Prime Cedar-Tone Ground Contact Pressure-Treated Lumber
I bought 4 in. x 4 in. x 6 ft. Pressure-Treated Cedar-Tone Moulded Fence Post
I bought #9 x 2-1/2 in. Star Flat-Head Wood Deck Screws
I cut the 2 X 6's into 3' sections. And I cut the posts into (4) 11" pieces.
In the picture I laid out the lumber in the grass. Then I placed it on a flat surface and put it together without any screws.
I will be planting sunflowers in this raised bed. No veggies. Veggies and pressure treated wood are not a good combination.
Step 2: Screw It All Together
Since I'm placing 2 boards on top of each other to create a higher raised bed, I like to join the wood using these Simpson Strong-Tie 1-13/16 in. x 5 in. Tie Plate or whatever size you want. I do this because some of my raised beds have buckled from the weight of the soil inside. These plates help to hold it together.
Then just screw everything together with long deck screws.
Step 3: Project Completed
Drag your finished raised bed out to your garden area, leaving ample space between raised beds to fit a lawn mower.
When it's time to add soil, I'll get a shovel and dig, dig, dig inside the raised bed, get all that grass out of there, to make room for the soil.
