Concrete Block Raised Garden Beds

Concrete Block Raised Garden Beds

One way of making a raised bed that will last for years is to construct these from concrete blocks. Just like our dwelling houses, these constructions will last for decades and will not need to be repaired or replaced, if done properly and correctly from day one. I would like to explain before we go any further that, there are two types of concrete blocks that are suitable for this project. The solid concrete block which is made from solid concrete, aggregrate and sand and the other type that we may have heard of also is the breeze or cinder block, which is also made from the same material.  The difference between the two is substantial in building circles and one is more expensive than the other. The solid concrete block is solid all the way through, hence the name and the other has hollow compartments, again hence the name breeze or cinder.

However the fact remains that if we have a good trades person or contractor when building our concrete block raised bed garden, either option will work. For the construction of this project, the work will have to be professional up to a point, in that, when laying the blocks, mortar will be required to tie all the joints together, just like constructing the walls of a house or garage. We could, if we were up to it, do this exercise ourselves, if we had the know-how and this route would save a great deal on the cost. There are hundreds of tutorials online and on YouTube, on how to lay blocks,  how to lay a foundation and also on how easy they claim it is to rener the walls afterwards.

One issue that we need to take into consideration when we are considering making a raised bed from concrete blocks and that is, we need to realise that this will be a permanent structure. So therefore we will have to give this project a considerable amount of thought and decision making into where we wish to locate these garden beds. Like we mentioned previously in this website, if it’s possible, locate these near a water sourse for irrigation purposes. The above image shows how good a well built raised garden bed looks, when it is professionally constructed. The planning in this example was well considered and as you can see a foundation was laid out and then the blocks placed appropriately on the level prepared surface.  The end result looks very neat and tidy and has an appealing appearance. A professional approach for this job will enhance our gardens and backyards. At a cost of approx $1·30 per block and add in the labour, we are looking at an investment of approx $150.

In the above example we see a different take on what a concrete block raised garden bed looks like, if we don’t approach this exercise with a little planning and proper preperation. As we can see the design is not exactly aesthetically appealing and it looks very shoddy and careless. This will not last 12 months as the soil will eventually press against the sides and eventually the sides will fall away. There is no foundation in this attempt and the blocks look like they were just placed on the ground without little or no formation or consideration to the appearance of the raised bed. The upside to this example is ( if there is one ) that the cost was at a minimum. The outlay for this exercise would amount to approx $20, which is fine if our budget is restrained by other circumstances. The only good thing that’s to be said about this example is, it can be easily relocated if required.

The above image shows what a professional well thought out and carefully constructed raised bed could look like, if our budget allowed. It looks like it has been designed by a construction engineer and built off a set of designed plans. However this operation could easily undertaken by a blocklayer on their own. With a set of measured foundations and level surfaces to work on, its very easy to complete this set of raised beds from solid concrete blocks. Proper planning and matching dimensions for each section will result in an awesome outcome and a series of concrete block raised beds that will last for years.

Once the walls of the sections had been completed they were then rendered to give a very artistic and professional outcome. It has a symmetric and square design and looks like it was factory produced. From the location of these concrete block raised beds, we can see that its situated at about four feet from the hedge on two sides and that gives ample room to work on these with ease and comfort. The cost for this structure will be approx $2000 plus. Materials and labour will amount to most of the outlay and if there were plans and design to be paid for, these would cost extra. The upside of this investment is, it will pay us back in spades over time, as we will thoroughly enjoy working in an envoirnment like this.

Let’s now look at something different thats very functional from a raised bed gardening option. These are cinder blocks that interlock and give a very solid bed frame base for our gardening purposes. These blocks are obviously more expensive that the other two varieties that we looked at here earlier. The end result is a super looking raised bed that will be very inviting to all gardeners and especially by senior gardeners, who would welcome the height of this construction. No bending, kneeling or stooping with these and that’s to be welcomed even by those of us that don’t have mobility or health concerns. It looks very inviting and appealing and as we can see it makes a great garden piece and would also make a great conversation piece. The cost of an outlay of this would come in at about $1000 and would be money well spent.

  1. Phil,
    I loved reading this because I grew up with raised beds. My Dad grew everything for us to live in the Alaskan bush. We had huge gardens that produced enough to last us all winter. Those were raised beds with no structured sides. The raised beds are necessary here to allow the soil to warm up faster in the spring.

    Later I helped Dad construct a cinderblock raised bed here in the city to grow peonies. He has passed away now but the bed and the peonies are still there.

    It is great to see a site like yours since so few people garden anymore! It was a ton of work but we really enjoyed it. Of course we were not on the road system so every supply had to be driven out from town hundreds of miles, then flown our in our small plane, then transported from the airstrip by 4 wheeler. Every bag of cement was a ton of work! We collected all we could locally like soil, sand from the rivers, stones from the mountains and dead leaves in the fall for mulch. We had compost piles and chickens and rabbits as well as a dog team.


    1. Hi there Jessica,

      Many thanks for stopping by and taking the time to offer such a great comment feedback, its very much appreciated. I agree with you that raised beds do make gardening so much fun and also very enjoyable.

      You had such a great upbringing and I know that your Dad must have been a great gardener, he was a great believer in the garden and I will bet that he was a great provider for you and your family.

      That is exactly how I learned everything that I know about gardening today, I used to watch my father gardening and learned all there was to know from him.

      Thanks again for stopping by and happy gardening

  2. Thanks for the great idea. I have heard about similar concrete garden beds but never considered it for my own garden. The main reason why I see it a good idea is a low cost and ability to create any configuration flower beds.
    I hope that the budget of about 200 EUR plus own labor is ok for my next garden bed.

    1. Hi there andrejs,

      Many thanks for stopping by and offering feedback comments. I am glad that you liked this post and it’s just another option or set of ideas on how we can be innovative and versatile, when it comes to plans for our raised bed gardens.

      The budget that we have to spend, absolutely will dictate what size, shape and material that will go towards the make-up of our raised bed garden and at $200 you will get a good size framed construction, I am sure.

      Thanks again for stopping by and happy gardening,

      Cheers    Phil Browne.

  3. I would have never thought of this, even though I’m sure I’ve seen them around. I love option number 4 as I have back problems. Definitely something to save up for a research more, since I don’t want anything like option number 2. Thank you so much for posting this, as I’m definitely excited at the possibilities!

    1. Hi there Michelle

      Many thanks for reviewing my post on concrete block raised beds, its very much appreciated. I am gald that you found the information useful and beneficial. Definitely option no. 4 looks like the real deal. Its the right height for easy working and maintenance  and would look very attractive in any garden

      Thanks again for stopping by,

      Cheers      Phil Browne.
