How to Make Raised Beds for a Vegetable Garden
How to Make Raised Beds for a Vegetable Garden
After clearing the overgrown land and turning the soil, the next important step in our Raikana Primary School garden project was to shape the land into raised beds.
When I say raised beds, I am talking about raised areas of soil created directly from the ground. We did not build wooden boxes or buy special garden structures. We used the soil that was already on the land and shaped it into organised planting beds with spaces between them.
This is a method I have been using for years. I first learned the importance of raised beds while working with Emnes Elliott Baloyi at our old project, Alkemetic Vegetation Farm. The conditions there taught us that how you arrange your garden can be just as important as what you plant.
I later used the same approach at St Francis Primary School, and I am continuing to use it here at Raikana Primary School in Pretoria, Gauteng.

Why I Started Using Raised Beds
My experience with raised beds did not start at Raikana Primary School.
At Alkemetic Vegetation Farm, Emnes and I were working on land that had a significant slope. The farm was also located near mountains. During periods of heavy rainfall, water could move down from the higher areas and through the farm.
Because we were working on sloping land, we had to think about what would happen to the soil and vegetables when large amounts of water moved through the area.
We learned from experience that simply planting vegetables on flat ground without considering the movement of water could create problems. Plants could be disturbed or even uprooted when water moved strongly through the garden.
That experience is one of the reasons raised beds became part of my gardening method.
Working With the Slope and Water
One of the biggest lessons I learned is that garden beds should be planned according to the land.
At Alkemetic Vegetation Farm, we arranged our beds in relation to the slope because we needed to manage how water moved through the farm. The arrangement helped us create defined growing areas while giving excess water clearer pathways through the garden.
However, this does not mean that every raised bed should simply run straight downhill.
On steep or erosion-prone land, directing water straight downhill can actually increase runoff and soil erosion. Depending on the site, gardeners may need to consider contour planting, terraces, drainage channels, swales or other water-management methods.
The important lesson is this:
Look at your own slope, soil, rainfall and drainage first. Your garden layout should help manage water rather than fight against it.
From Alkemetic Vegetation Farm to St Francis Primary School
The raised-bed method became something I carried with me as my gardening journey continued.
After learning from our experience at Alkemetic Vegetation Farm, I used the same general approach at St Francis Primary School.
For me, this is one of the interesting things about gardening. A technique does not always come from a textbook. Sometimes you learn because you make mistakes, observe what happens, change your approach and then use what you learned somewhere else.
That is exactly how this method developed for me.
Continuing the Method at Raikana Primary School
In 2026, Emnes and I started working on the garden at Raikana Primary School in Pretoria.
Before creating the beds, we had already cleared the overgrown land and turned the soil. There were grass roots, rocks and other material in the ground that needed to be removed before we could properly organise the planting area.
Once the soil was worked, the next job was to give the garden structure.
This is where the raised beds came in.
How We Shaped the Raised Beds
Creating these raised beds was manual work.
We used shovels and hand tools to move and shape the soil. Instead of bringing in expensive materials, we worked with the soil that was already available on the site.
The basic process was:
- Prepare and loosen the soil.
- Remove remaining large roots, rocks and unwanted material.
- Decide where the individual planting beds would run.
- Move soil toward the centre of each bed.
- Shape the sides of the beds.
- Create clear spaces between the beds for walking and maintenance.
- Level and smooth the planting surface.
The goal was not to create perfectly manufactured structures. The goal was to create useful, stable planting areas that we could maintain season after season.
Shaping the Soil Into Defined Growing Areas
In the photographs from this project, you can see how the loose soil gradually becomes organised into long raised beds.
The soil is pulled and shaped so that the growing area sits higher than the pathways between the beds. This creates a clear separation between where the vegetables will grow and where we will walk.
This simple separation becomes very useful later.
Instead of stepping on the growing soil every time we need to work in the garden, we can use the spaces between the beds as walking and working areas.
Leveling and Smoothing the Planting Surface
After the soil was moved into position, we still had work to do.
A raised bed should not simply be a pile of soil. The growing surface needs to be shaped into an area where vegetables can be planted comfortably and maintained throughout the season.
We therefore worked across the beds, breaking down larger clumps and smoothing the soil.
This is especially useful when preparing an area for smaller seeds. A rough surface with large clumps can make planting depth inconsistent, while a reasonably fine and level surface makes it easier to place seeds at the desired depth.
The photographs show this process clearly: the beds become more defined as the soil is moved, shaped and smoothed.
Creating Space Between the Beds
One thing that I find very useful about raised beds is the space they create between planting areas.
These spaces become pathways.
Pathways allow us to move around the garden without constantly stepping on the soil where the vegetables will grow.
They also give us access to the plants when we need to:
- Remove weeds
- Apply fertiliser
- Inspect plants
- Water the garden
- Harvest vegetables
- Replace finished crops
- Perform general garden maintenance
A well-planned pathway can therefore make a garden much easier to work in, especially when the garden is going to be used repeatedly.
How Raised Beds Help With Water Management
Water management is one of the biggest reasons raised beds became important in my own gardening journey.
Raised beds can help create a defined root zone while the lower spaces between beds provide areas where water can move. The exact result depends on the soil type, rainfall, slope and drainage of the site.
In our case, the experience at Alkemetic Vegetation Farm taught us to pay close attention to how rainfall moved across sloping land.
Raised beds are not a magic solution for flooding. If a garden receives very heavy rainfall, the whole site still needs proper drainage and water management.
But organising the soil into beds and pathways can make it easier to control where plants are growing and how water moves around those growing areas.
What Happens to the Roots?
Another reason I like raised beds is the growing environment they can create for plant roots.
Vegetables need enough soil space for their roots to develop. Compacted soil can restrict root growth and make it more difficult for water and air to move through the soil.
Because we had already turned the soil and removed many of the old grass roots before shaping these beds, we were creating a more organised growing area for the vegetables that would come next.
The important thing is not simply that the soil is raised. The soil should also be reasonably loose, workable and suitable for the crops being planted.
Raised Beds Make Fertilising Easier
Another practical benefit I have found is that fertilising becomes easier when the garden has clearly defined beds.
Instead of applying fertiliser randomly across a large piece of land, I can work systematically along each planting bed.
This is especially useful in a vegetable garden where different crops may eventually have different nutrient requirements.
For example, the Raikana Primary School garden is planned for crops such as:
- Swiss chard spinach
- Garlic
- Kale
- Beetroot
- Onions
- Leeks
- Cauliflower
Having organised beds will make it easier to manage these crops individually as the garden develops.
Raised Beds Can Become Permanent Garden Beds
When I say that I use these beds for permanent gardening, I do not mean that the same vegetables stay in the soil forever.
What I mean is that the bed structure remains in place.
At the end of a growing season, I can remove the finished vegetables and plant new crops without completely rebuilding the garden.
I mainly remove weeds by hand, harvest the vegetables when they are ready, remove finished plants and then prepare the same beds for the next crop.
This saves a lot of unnecessary work compared with rebuilding the entire garden every season.
Raised Beds vs Planting on Flat Ground
There is nothing wrong with planting vegetables directly on relatively flat ground. Raised beds are simply another way of organising a garden.
From my own experience, however, the difference becomes noticeable when you are managing a larger vegetable garden or dealing with difficult site conditions.
| Raised Beds | Flat-Ground Planting |
|---|---|
| Clearly defined growing areas | Growing area may be less defined |
| Creates dedicated pathways | Pathways need to be planned separately |
| Can make soil management more organised | Soil may be managed across a broader area |
| Can make fertilising more systematic | Fertilising may be spread across a wider area |
| Useful for organising repeated seasonal planting | Can also work well for seasonal planting |
Raised Does Not Mean Higher Is Always Better
One mistake beginners can make is thinking that a raised bed needs to be extremely high.
That is not necessarily the case.
The height of a raised bed should depend on the soil, crops, drainage, available material and the way the garden will be maintained.
In this project, we were working with the soil already available on the site. We shaped it into practical raised beds rather than trying to build very high structures.
The objective was to create functional planting areas, not simply to make the beds look tall.
Raised Beds Still Need Water
Another important point is that raised beds do not eliminate the need for irrigation or rainfall.
In fact, depending on the soil and climate, raised soil can sometimes dry out faster than surrounding ground because of increased exposure and drainage.
This means you still need to monitor the soil moisture and provide water when necessary.
Good drainage is important, but so is keeping enough moisture available for healthy plant growth.
Why I Prefer This System for My Vegetable Gardens
For me, raised beds are not just about appearance.
They give the garden structure.
Once the beds are established, I know where the vegetables will grow, where I will walk, where I can apply fertiliser and where I can work when removing weeds or harvesting.
They also allow me to keep improving the same growing areas over time rather than starting from zero every season.
This is especially important for me because my gardening journey has always been practical. I am learning by doing, observing what works on different sites and carrying those lessons into the next garden.
Lessons I Learned From Making Raised Beds
-
Look at your land before creating beds.
Understand the slope, drainage and natural movement of water. -
Do not assume every garden needs the same layout.
What worked for me on sloping land may need to be adapted for another garden. -
Prepare the soil first.
Removing roots, rocks and unwanted material makes bed formation much easier. -
Create useful pathways.
Leave enough space to walk and work without repeatedly stepping on the planting beds. -
Do not make beds unnecessarily high.
The purpose is to create productive and manageable growing areas. -
Think about long-term maintenance.
A good bed layout should still make sense after planting, fertilising, weeding and harvesting begin. -
Learn from your own garden.
My raised-bed method came from experience at Alkemetic Vegetation Farm and was later adapted for other garden projects.
My Raised-Bed Gardening Journey
Looking at these beds today, it is easy to forget that this method came from problems we faced years ago.
At Alkemetic Vegetation Farm, Emnes and I had to deal with a sloping site, rainfall and water moving through the farm. We did not have a perfect gardening setup or expensive infrastructure.
We learned by working the land.
Those lessons stayed with me.
From Alkemetic Vegetation Farm, to St Francis Primary School, and now to Raikana Primary School, the raised-bed method has continued to evolve with each garden.
The beds you see in these photographs are therefore more than just rows of soil. They are part of a gardening method that I have developed through years of practical experience.
What Came Next?
Once the raised beds were shaped and organised, the next step was to prepare the soil and protect it before planting.
In the next article, I will show how we used mulch before planting and why covering the soil can be an important part of preparing a vegetable garden.
