Raised Beds on Concrete

Raised Beds on Concrete

If we are thinking of building  raised beds on concrete, this is a fabulous idea and can very easily become a reality.  It is a concept that has many advantages, not overly expensive and  when complete, looks very appealing and attractive. We have two options to look at here; firstly, we can construct this on a concrete surface, which will make for a solid foundation and secondly we can easily construct a raised bed from concrete or builders blocks which we can locate in our backgarden. Either of these two  options will work and both ideas can become very worthwhile projects.

If our backyard is completely concreted over,then obviously we have an ideal surface for your raised bed.  If we decide to carry-out this job ourselves, select a nice level area and begin building with the first course of blocks. A height of two rows high should be sufficient as this will give your bed a depth of approx 1-2ft. The standard size of these beds is about approx 8-10ft x 4 ft, but it can vary depending on the amount of space we have and also the amount and type of building materials.

 

Building a raised bed on concrete;

 

Hiring a blocklayer or tradesman would be a great idea for this project, as we need this task to be a job that looks well, is sturdy and it also needs to be waterproof. We don’t need any excess brown coloured water to be seeping from the bed as it would look very unsightly and could easily discolour your existing concreted surface. Before we fill this concrete raised bed with soil, we will need a small layer of gravel and stones on the bottom to absorb any excess water. This system ensures that the bed never dries out completely, as plant roots will always reach downwards in their search for water.

 

 

Concrete raised beds in our backgarden;

 

Building a raised bed from concrete blocks on your garden surface is another option. For this job I would strongly advise hiring a blocklayer or tradesman again. The reason is something  similar to above. We need to dig a trench roughly the size of our bed frame, a base foundation of mortar is made for the blocks. The reason for this is to create a solid foundation so as to prevent subsidence and thereby giving us a solid base for our concrete blocks, which will  make the walls of our raised bed. This method will make a sturdy, safe, sustainable structure and should last a life-time. We might consider this method  expensive, but if we have any blocks lying around from a previous building project, these will also suffice and will help defray some of the project costs.

 

In summary;

 

The two above methods of raised beds on concrete are both rot and pest resistant. The other great advantage is that the blocks, which are made from concrete, will hold most of the heat from the mid-day sun and carry same well into the night. This extends growing periods and provides healthy, sustainable conditions for your plants, vegetables, flowers or shrubs. If we ever need to erect a polythene cover over our bed we have a sturdy structure for implementing and installing this option. A strong sturdy trellis can easily be added to the equation as we have strong base walls to support and attach same.

 

Happy gardening to all,

  1. I am one of the unfortunate as I do not have a garden to call my own.

    There is land around my property but I do not have the permission to use it for gardening purposes.

    I do however have 3 balconies and was wondering if it is possible to apply the methods you talk about here on one of them?

    Great information and it has given me some ideas!

    Thanks

    1. Hi there, Chris.

      Many thanks for your site feedback and comments. Its unfortunate that you cannot make a raised bed on your property, as I can see that you are very enthusiastic about them. Yes you can easily have raised beds on your balconies, they would make a great focal point to be looking out at, from your kitchen, living or sitting room. Have’nt we all seen people with flower pots and window boxes on their balconies. Afterall, a raised bed is just a large planting box. However I would caution that it is imperative that we line these raised beds with a waterproof, membrane liner, as you don’t want the watering of these to cause leakage or seepage out onto the balconies as it would look unsightly and could cause discolouration. If you know a handyman/woman, they could make them to your speficitations and would absolutely look very attractive when planted with flowers or veg etc. Thanks again for your comments.

      Best wishes………………Phil Browne

  2. I like the layout of your website, you seem very passionate about raised beds. Your website is very informative and easy to navigate. Your headlines and images go very well together.
