I am not handy with tools, so remember, if I can do this, you can too. All you need is a drill, some drill bits, and 3” outdoor screws.
Go to your closest lumber store and purchase 2 boards and ask them to cut them for you. I got mine at Lowe’s and they did not charge extra for cutting them. I bought the cheapest wood I could find and because this is for vegetable gardening, I did not want treated lumber. 2×12 by 12 foot long. If you have them cut 4 feet off each board, you will now have 2 – 8 ft boards and 2 – 4 ft boards which is perfect for an 8×4’ garden bed! If you go online, you could probably find the price for lumber in your area, I think it cost me about $35 for 1 bed. I was so worried that the boards would eventually bow and warp that I also purchased 8 – 24” rebars (about $2 each)that I pounded into the dirt about 1 foot below ground level on the outside of the boxes (which left 1 foot showing). They were placed at each corner and two in the middle of each long side, so 8 total rebars for one bed. The reason I left 1 ft showing was for the cold months when I would want to cover the raised bed. As you can see I just eyeballed the spacing and depth. Also, I’ve had these first 2 beds for going on three years now and they haven’t warped at all.
A PVC pipe fits perfect over the 1 ft rebar and I just bend it over to the other side. Super easy to set up and tear down. I used another PVC for the ridge pole and wound some twine around the intersections to hold it in place. Then I got some heavy-ish plastic sheeting to cover it. I gathered and stapled the ends to a 4 ft 2×2 to add some weight so the winds wouldn’t blow it off. And it held up great to some fairly rough winds and a few inches of snow even! It may not be the prettiest but it got the job done without extensive carpentry skills.
This year, I decided to add two more 8×4’ raised beds, then went on to add a third 8’x4’ and a 4’x4’. The most expensive part is filling it. The least expensive way to fill it is to take a pickup and a tarp and go to the local nursery that sells garden soil by the yard. They will dump ½ yard of it in my pickup bed (on the tarp which I then wrap over the top to keep it from blowing away before I get back home). This is a bit more labor intensive for me instead of buying bags at the big box stores but it is cheaper in the long run. I don’t fill the beds to the brim because every year, I add compost and mulches that get worked in.
Materials I used for a basic raised bed:
- 3” outdoor screws, 4 on each corner, 16 total
- Small drill bit to pre-drill each hole
- Ryobi Battery-powered drill
