At Grow Pro Topsoil we often get asked ‘how do I build a raised bed?’ –  the answer is often easier than people imagine.

Raised beds are a modern feature in Irish Gardens, and they aren’t just great for aesthetics, raised beds also promote the growth of different plants and vegetables if you’re planning some authentic home-cooked dinners for this winter.

Now, you may think that creating a raised bed is simple enough, and you would be right, but there are some crucial steps to follow, so stay with us here for a few minutes.


1. Decide On Size and Position

It may sound obvious, but before you start any work, be very clear on what you wish to grow in your raised bed as the depth and soil type will be determined on this decision.

2. Leave Space to Walk Around

You would be surprised the number of gardeners who create their raised bed and don’t leave any room to manoeuvre around them, leaving no other option than to trample on the soil and plants!

Here are some guidelines to follow;

The minimum depth for raised beds is 20cm (8In). However, some plants need 45 – 60cm (18-24In) to grow, so be sure to check this with your local garden centre. If you are growing root vegetables, you will need even more depth at 60cm (24In). Lastly, if you are placing the raised bed on a hard surface, you will need to allow for a depth of 40cm (16In).

3. Lay the Foundation

Equipped with your tools and measurements, the next phase is where the fun really begins. Mark out where your raised bed is going to be placed and clear the area to create a level foundation.

Note, if you have a tall bed of over 50cm (20In) remove some of the existing topsoil and add some broken bricks and sand to assist with drainage.

We promise there are no more measurements to come!

4. Select Your Material.

So you know the plants you are going to put down, but what material are you going to use to make your bed? We recommend investing in sleepers as they will last for a really long time and they look great in a garden.

Once you have your sleepers, you will need to add stakes to each corner of the bed. The best practice is to use 5cm timber stakes and dig down into 30cm of soil.

To attach the stakes to the bed, use screws or nails to secure them in place. It goes without saying, but do be sure to have someone helping you when you are doing this part.


4. Attach Side Walls

Attach your raised bed side walls to the stakes with nails or screws to secure them firmly in place.

Top tip: Use a spirit level to check the stakes are straight vertically and horizontally

5. Add Your Topsoil – The Magic Ingredient

You must add high-quality topsoil to your raised bed to give it the best chance to flourish. We should be able to help you with that…Shop Now

Add your topsoil to the bed and make sure that it is level with the top of the frame. Don’t worry as the bed matures, the soil will sink into it.

After a year goes by, be sure to add more of our nutrient boosting topsoil to the bed to give your plants the best chance to perform to their best.

And that’s all folks.
