A few months ago my darling husband decided to appease my spontaneous idea of a garden (though historically, I have a very black thumb) and went a step further to build me a few beautiful DIY raised garden beds with corrugated metal and redwood. I’ve had so many people ask for the details about how he made them that I decided I had to share them here!
For each of these raised garden beds, you’ll need:
2 – 4′ x 8′ pieces of corrugated metal
1 – 4″ x 4″ x 8′ piece of metal flashing, cut into 4 – 22″ sections
4 – 2″ x 3″ x 8′ pieces of wood (we used redwood) for the box frame
2 – 3″ x 4″ x 8′ pieces of wood ripped in half for the decorative box top
Optional: 4×4′ chicken wire for the bottom of the box (to prevent animals from tunneling under the box)
A few notes:
Cutting the corrugated metal was definitely the toughest part. You’ll need two people to do it, and safety glasses are a must. We purchased a blade for the skill saw specifically used for cutting metal.
These aren’t the most cost effective boxes you can make, but they’re beautiful! Each box cost us approximately $100. You can use different wood to get the price down.
The corrugated metal has to be vertical for structural purposes.
1. Cut your supplies. You’ll need to cut the corrugated metal and metal flashing into four 22″ sections, the redwood for the box into eight 48″ sections, and the redwood for the decorative top of the box into four 48″ pieces that are ripped in half (cut in half) to make it look a little nicer. Here’s a picture for that last one, where you can see the thinner top piece:
2. Use four of the 2″ x 3″ x 4′ pieces of wood to make the bottom frame of the box. Once we cut the corners to fit together, we used deck screws to secure them together.
3. Next, we fastened the metal flashing to the corners of the bottom frame of the boxes. This was definitely easier to do with two people.
4. Now for the corrugated metal. Again, easier with two people. Steve sat inside the box while I sat outside with a right angle, making sure the metal was straight before he screwed it in place.
5. After securing the corrugated metal, we flipped the planter over so the metal fit just inside of the other box frame. We secured that with deck screws.
6. Optional: Secure the chicken wire to the bottom of the box with a staple gun. Again, we did this to make sure no animal could tunnel under the boxes.
7. Flip the box back over and secure the top decorative frame to the box. This makes the box a bit more polished and gives you a place to sit or place garden tools.
After securing the top, we carried the planter outside and pulled our drip tube through the chicken wire.
8. We filled the boxes with soil, making sure the drip tube stayed at the top.
We were gardening newbies when we started, but I have to say that I think we’ve done a pretty good job in the last few months!
Now, what will you fill your raised bed gardens with?
