12 Amazing Cinder Block Raised Garden Beds (2024)

There are limitless ways to grow a garden, and one of our favorites is in raised beds. Raised bed gardening has manybenefits over other growing options.

Because the soil is not continuously getting stepped on, it stays loose and well-drained, and raised beds are simply easier to plant and maintain since they are off the ground. Raised beds can also deter some pests – like gophers and rabbits – from reaching your precious plants.

Raised beds can be made from all kinds of materials, but I love the idea of using cinder blocks because they have many advantages of their own. First, they won’t deteriorate like wood and other materials will.

Second, they are built to stack, so it is easier and quicker to create a raised bed with blocks than with most other materials. Just stack them in any shape you want, fill with dirt, and plant.

And third, they are cheap. You can buy them at most home improvement stores and you can often find them for free from places like Craigslist and Freecycle.

Need a little inspiration? We’ve gathered up 12 examples of different ways gardeners are using cinderblocks to build raised beds.

First, we haven’t found any cinder block garden beds more practical than these incredible grow beds built by Jon Hughes. These can be seen on his YouTube channel.

In most of his cinder block beds, Jon plants a variety of vegetables in the center and onions in the perimeter holes. He grows enough food to donate a huge amount to his local food bank.

I love the fact that Jon utilizes the holes in the blocks for plants. I could see this method being useful for creeping plants as well, as a way to keep them confined to specific areas.

Casey from Oklahoma Gardening demonstrates step-by-step how cinder blocks can be used to build these raised garden beds. She uses the holes in the blocks to insert PVC pipe, creating an easy, handy hoop house over the beds.

In this example, the hoops are used for cover cloth to keep squash bugs off the plants. This is a great idea for crops prone to pests, and could also be used to protect sensitive crops from the elements and to extend your growing season.
