Today I’m going to show you how to build cedar raised beds. If you have been following along in our gardening journey so far, you may have seen our vlog all about our cottage garden, and have gotten a sneak peak at the cedar raised beds we built.

These raised beds were so easy. They only took one day get the beds together, get them filled, and get planted. And we did six! Seriously, it’s that easy.

When we moved into the farm in January, we knew the garden would be a project we would tackle in year one. We love being able to grow a lot of our own food, and we’re excited to continue to expand it each year.

There is something so satisfying about learning, growing, and enjoying the food you produce on your own land, knowing what went into the soil, the kinds of seeds, and all the hard work. But that hard work is so worth it when you get to bite down on a crunchy sweet pepper or into a home-grown, juicy tomato. Truly, there is nothing like it.

I love how much the kids get out of it. You can often find them in the garden chomping away at the vegetables.

Cheap Raised Garden Bed

You’ll need six cedar fence posts for one raised bed. The reason we went with cedar fence posts is because it was the only affordable cedar that our local lumber yard had on hand. Plus, it’s just a really cheap way to go. The posts cost around $2 each, making each cedar raised bed cost less than $15 total. We also repurposed some lumber we had on hand to join the corners.

Now, we went with cedar because it is naturally rot-resistant, and we didn’t want to purchase treated lumber because we didn’t want that treatment leaching into the garden, the soil, and our food.

So lets grab some lumber and your tools, and let’s get to building these cheap raised garden beds.

Benefits Of Raised Beds

  • Kids don’t run on top of the soil (which compacts it), or get into your veggies as much.
  • Less weeding than traditional gardens created right in the ground.
  • You can fill them with whatever soil you can find. Get good soil and add lots of it!
  • Space-saving: you don’t have to garden in rows. The boxes themselves create the rows.
  • The square foot garden is a great way to grow a lot of food in a small amount of space.
  • It is much easier to get in the garden to harvest and weed because they are raised up.

What kind of wood should be used should be used for raised beds?

Cedar is the most affordable, and is naturally rot-resistant due to natural oils in the wood.

Redwood is very expensive, but is rot-resistant and has a long longevity.

Douglas Fir is a very affordable option, but won’t last as long as redwood or cedar in terms of longevity.

While pressure-treated wood could technically be used, it could leach chemicals (like fungicide and copper) into the soil, and is not approved for organic use.

How deep should a raised garden bed be?

A raised bed should be a minimum of 6-12 inches deep, so there is enough room for your plants to develop a good, deep root system, but you can make the raised bed as deep as you would like. If your bed is not 12 inches deep, you could dig out a bit of the ground before adding the dirt to make it deeper.

Materials Needed To Build Raised Garden Beds:

This is for one raised bed. If you are planning to make six beds, then multiply the materials by six.

  • 6- 6 foot pieces of Cedar – we used 6 foot long cedar fence posts
  • 6- 10 inch long 1x2s, or 2x4s ripped in half
  • Screws
  • Circular Saw
  • Drill

How To Build A Raised Garden Bed Tutorial

  1. Cut off the top part of the cedar picket fence.
    • This isn’t something you have to do; we just decided to square off the top to make it look a little cleaner.
  2. Measure the cedar fence pickets. Cut 2 boards in half.
  3. Each post was 6 feet long, so we cut each in half to make two 3-foot boards. These will be the ends of each raised bed.
  4. Take two of the long pieces of cedar, lay them next to each other, and line up the ends.
  5. Place one of the 10 inch long 2x4s cut in half (or 1x2s) to one of the ends of the long cedar boards and drill in.
  6. Stand it up with the cedar board touching the table; the ripped 2×4 is up and part of it is above the cedar.
  7. Place the short end piece next to the long piece creating a 90 degree angle and screw it into the ripped 2×4. Continue doing this until all four boards are attached.
  8. Add the second layer of cedar posts and screw them into the ripped 2x4s.
  9. In the center of the long side of the raised bed, screw in another ripped 2×4.
    • This helps add support so it doesn’t bow out once the soil is added.
  10. Put them in place and add soil.
    • When installing the raised beds, it is a good idea to allow enough space between each bed to make it comfortable to walk through and bend down.
