Making Elevated Patio Garden Boxes

Hey guys, I'm finally getting my Garden Box Vlog down here on the blog! I'm going to go through the reasons why we built our elevated garden boxes, why we made them the way we did, and how to build them! 

 In the being of summer in 2019, I REALLY wanted a patio garden box to grow lettuce in. Our main garden area was not suitable for salad greens, and I desired to grow a fresh salad! We had a couple of 2x10x12 boards under our shed from a previous project, so we fingered why not?

  

Our first patio box was planned based on what we had on hand. Truthfully we did not have a plan, and we really should have. We ended up with a 6ftx2ftx5ft garden bed and planted the bed with lettuce and carrots. The bed was successful, and after three rotation harvest of lettuce, the carrots were ready for picking. Then the bed was turned into a pepper bed. It worked so well that I plan to revise our patio into an elevated raised planter garden!

 

Why I wanted this style garden:

  1. Easy to go right outside my door and pick fresh veggies.
  2. Easy maintenance- Easy to gather food, pick weeks out, and watch for pests or problems. 
  3. Made my porch space more functional.
  4. Elevation keeps animals and kids out of the beds. 
  5. More control over my gardening.

We do have a large garden at the bottom of our property that we use for all the veggies that we put up for canning and freezing. But it is not a functional space for growing greens and carrots. 

 

Things to consider before building:

  1. Make a plan on where your beds will go and what you want to plant in them. 
  2. Study your lighting, how will the sun hit your bed? I planned for a while and knew how the sun would cross my patio. 
  3. These are heavy materials, you will more than likely need help with loading/unloading and building the beds. One possibility is partnering up with a neighbor who knows how to build or can help, then share in your food abundance when the bed is producing! 
  4. Because they are heavy, build them as close to your sight as possible for ease of moving.
  5. Put them in place and take the time to make sure that it is where you want the bed before you add your soil. The soil will make it even heavier! 
  6. If using treated wood is not your thing, then you CAN use untreated! You will still need to put a weed barer down to keep your soil from leaking out. 

 

Materials List: 

Boards: Treated or Non-treated 

1: 2in x10in x 12ft

1: 2in x 10in x 16ft

1: 4in x 4in x 12ft 

1: Box of Premium Exterior Wood Star Bit Screws 10x31/2"

1: Roll of 10ft x 20ft 3-mil or 6-mil plastic sheeting. Depending on how many beds you are making, you can buy up to 100ft of plastic. Research and pick what will work for your situation. 

1: Roll of WeedBlock Landscape Fabric, this also comes in different lengths and widths, so pick a size that will fit your situation. 

 

Tool List: 

Electric Drill

Skill Saw

Heavy-Duty Staple gun with staples

 

Cut list: 

2: 6ft (72") 2"x10" pieces 

8: 2ft (24") out of the 2"x10" boards

4: 3ft (36") out of the 4x4 piece

Side note: You may want to have two 13 1/2" 2x4 pieces to cap the ends of the beds at the bottom. 

 

Step One: 

Layout your two 6ft boards parallel to each other. Place one 2ft board at each end. Make sure that the 2ft boards are on the outside of the 6ft boards, and all sides are flush. Now one person will hold the boards in place while the other screws the screws in place. Each end of the 2ft board should have a screw at the top and bottom, screwing them into place on the 6ft board. Keep repeating this step all the way around, creating a 6ftx2ft rectangle. 

Step Two: 

Now you will screw your 4x4x3 legs into place. Leave your rectangle from the previous step in place on the ground. Now you will take each leg and place it into each corner. One person will hold the leg in place while the other screws. Put two screws into each side, a total of four screws per leg. 

Step Three: 

Now you will place your next six 2ft boards on top of the rectangle. Evenly space out your boards. One person can hold the boards, I stood on top of them to keep them from moving. Screw two screws (total of four) into each side of the 2ft boards. We felt the need to add a 13 1/2" 2x4 piece to cap each end of the bed so that the plastic/dirt would have support. Now carefully flip your bed over, be sure not to force too much pressure on any one leg, and your wooden bed is complete! 

Step Four: 

Now you will add your plastic. Roll out or unfold your plastic on the ground. I suggest you not cutting your plastic until you have placed the plastic inside the box, making sure you have enough for all sides and the bottom. Once you are sure of the fit, you can cut the plastic. Then staple the edges of your plastic at the top of the bed. I folded my edges to have a cleaner look. 

Step Five: 

Place a layer of weed block fabric along the bottom of the bed. No stapling is necessary. You may choose to cover the edges as well, that is your choice. 

Now your box is complete!
