How to Build a Cinder Block Raised Garden Bed
Last year we installed one Cinder Block Raised Garden Bed. We hoped to do three but our bodies and budget gave out at one.
Great news! We built the other two raised beds this year! Yay!
There’s nothing quite like growing your own food and I’m anxious to get going again this year!
After planting a tad too early last year, we are exercising our patience and waiting for Mother Earth News to tell us when to plant. It’s really quite slick! Just head over to What to Plant Now, click on >view planting dates, enter your zip code and email address, and it will send you a handy dandy email when it’s time to plant! Pretty cool, huh?
How to Build a Cinder Block Raised Garden Bed

Here’s the area we are working on. One lonely Cinder Block Raised Garden Bed and a whole bunch of moss with a splattering of grass.

First, we laid out the cinder blocks where we wanted them.
These cinder blocks are 8″X8″X16″ from Home Depot. The long sides of the garden bed have eight cinder blocks and the ends have three for a total of 22 cinder blocks per raised bed.
Note: I called these ‘cinder blocks’ but they are actually concrete blocks.
We plan to eventually add a second row of cinder blocks to match the center raised garden bed. It isn’t necessary but would make it easier on our backs. Perhaps next year!

Of course, the ground isn’t, even so, we either dug a little of the grass out underneath or used a bit of sand to make the cinder blocks line up. It really wasn’t too bad.

Next, we used painter’s paper, from the paint section at Home Depot, in the bottom of our beds. Newspaper or cardboard works great too!

Then, a half yard of compost/topsoil mix was used to fill both beds. They aren’t completely full but it works!

What To Put Around Cinder Block Raised Garden Beds
Wondering what all that cardboard is about? I knew you were!
Our original plan was to rent a sod cutter and remove the moss and grass, bring in a load of sand, and lay flagstone around our cinder block raised garden beds.
We decided our budget would like us better if we used pea gravel and, hey, why not just lay cardboard over the grass and dump the pea gravel right on top?
It was an easier and less costly option.
Steve dug out a trench for edging. We used the black plastic edging but, I have to say, I’m not too impressed. Someday we will have that cool concrete edging!

What To Plant In Your Cinder Block Raised Garden Bed
And voila! We are ready to plant!
It’s important to consider the fruit and vegetables you and your family will eat. There’s no sense in growing a bunch of green beans if no one will eat them, right?
