Onions are a staple in many South African households and are a versatile ingredient in many dishes. There are various types of onions that can be grown in South Africa, each with its own unique flavor and characteristics.
One type of onion that is commonly grown in South Africa is the short-day onion. Short-day onions require 10-12 hours of daylight to form bulbs and are typically grown in the Highveld region of South Africa. These onions are typically smaller in size and have a sweeter taste compared to other varieties.
Another type of onion that is commonly grown in South Africa is the intermediate-day onion. Intermediate-day onions require 12-14 hours of daylight to form bulbs and are typically grown in the central regions of South Africa. These onions are larger in size and have a more pungent taste compared to short-day onions.
Lastly, long-day onions are not commonly grown in South Africa due to the country’s climate. These onions require 14-16 hours of daylight to form bulbs and are typically grown in cooler regions.
Understanding the different types of onions and their growing requirements can help you choose the right variety for your garden or kitchen.
Varieties Types of Onions in South Africa
As a South African, I have grown up eating onions in almost every meal. Onions are an essential ingredient in many dishes, and it is essential to choose the right variety of onion for the desired taste and texture. South Africa has a variety of onion types, including red, brown, white, and intermediate types.
Red Onions
Red onions are a popular variety in South Africa and are known for their mild, sweet flavor. They are commonly used in salads, salsas, and pickled dishes.
The Red Creole variety is a popular red onion variety in South Africa and is known for its deep red color and sweet flavor. These onions are typically harvested in the summer months, and they can be stored for up to three months.
Brown Onions
Brown onions are the most common variety of onion in South Africa. They are known for their pungent, strong flavor and are used in many dishes, including stews, soups, and curries.
The Texas Grano variety is a popular brown onion variety in South Africa and is known for its large size and sweet flavor. These onions are typically harvested in the winter months, and they can be stored for up to six months.
White Onions
White onions are a milder variety of onion in South Africa and are often used in dishes where a more delicate flavor is desired. They are commonly used in Mexican cuisine and are known for their crisp texture.

Cultivation Practices – Types of Onions in South Africa
Soil Preparation
Before planting onions, it is important to prepare the soil. The soil should be well-drained and rich in organic matter.
I usually prepare the soil by adding compost or well-rotted manure. The ideal pH range for onions is between 5.5 and 6.5. If the soil pH is too low, lime can be added to raise it.
Sowing and Spacing – Types of Onions in South Africa
Onions can be grown from seed or sets. I prefer to use sets as they are easier to handle and give better results.
The sets should be planted about 2-3cm deep and spaced about 10cm apart in rows that are about 30cm apart. If you are planting from seed, the seeds should be sown about 1cm deep and thinned to about 10cm apart.
Watering and Fertilising
Onions require regular watering, especially during dry periods.
I usually water my onions once a week, but this can vary depending on the weather conditions. It is important not to overwater onions as this can lead to rotting.
Onions also require regular fertilising. I usually use an organic fertiliser such as bone meal or blood meal.
Weed and Pest Control
Weeds can be a problem in onion beds, so it is important to keep the area weed-free.
I usually mulch around the onions to suppress weeds. Onions can also be attacked by pests such as thrips, onion maggots, and onion fly.
To control these pests, I usually use an organic insecticide such as pyrethrum.
Climate and Regional Considerations – Types of Onions in South Africa
When it comes to growing onions in South Africa, there are a few climate and regional considerations to keep in mind. In this section, I will discuss the temperature and sunlight requirements of onions as well as the importance of daylight hours and crop rotation.
Temperature and Sunlight
Onions require a specific temperature range to grow properly. According to my research, the ideal temperature range for growing onions in South Africa is between 13°C and 24°C.
Onions also require plenty of sunlight to grow well. In general, onions need at least six hours of direct sunlight per day to thrive.
It is important to note that different onion varieties have different temperature and sunlight requirements.
For example, short-day onion varieties are better suited to the warmer regions of South Africa, while long-day onion varieties prefer cooler temperatures. Therefore, it is important to choose the right onion variety for your region.
Daylight Hours and Crop Rotation – Types of Onions in South Africa
Onions are photoperiodic, which means that their growth and development are influenced by the amount of daylight they receive.
Short-day onion varieties require 10-12 hours of daylight to bulb, while long-day onion varieties require 14-16 hours of daylight.
Crop rotation is also important when growing onions in South Africa.
Onions should not be planted in the same spot for more than two years in a row to prevent soil-borne diseases from building up. It is recommended that onions be rotated with crops such as maize, beans, or peas.
Growth and Harvesting – Types of Onions in South Africa
From Seedlings to Mature Onions
Growing onions in South Africa requires careful planning and attention to detail. The process begins with planting onion seeds or onion sets (small onion bulbs) in well-draining soil with good fertility.
It is important to choose a sunny location for the onion bed. The best time to sow onion seeds is from February to the end of March.
Once the onion seeds are planted, they will start to germinate within a week or two. The seedlings will need to be thinned out to ensure that they have enough space to grow. The spacing between onion plants should be around 10-15cm apart.
After about 3-4 months, the onions will be mature and ready for harvest.
It is important to keep the soil evenly moist during the growing period. Onions require a lot of water, especially during the hot summer months.
Harvesting and Drying Process
When the onions are mature, they can be harvested by gently loosening the soil around the bulbs and lifting them out of the ground.
It is important to handle the onions with care to avoid bruising or damaging them.
After harvesting, the onions should be stored in a dry, well-ventilated area for a few weeks until the outer skin becomes papery.
The drying process is important to ensure that the onions can be stored for a long period of time.
If dried correctly, onions can be stored after harvest until needed or marketed at a time when prices favour the grower. The curing process can take up to three weeks, and it is important to ensure that the onions are stored in a cool, dry place with good airflow to maximize their shelf life.
Storage and Shelf Life – Types of Onions in South Africa
As with any vegetable, proper storage is crucial to maintain the quality and extend the shelf life of onions. In South Africa, onions can be stored for several months if they are stored correctly.
Optimal Storage Conditions
Onions should be stored in a cool, dry, and well-ventilated place. Ideally, the temperature should be between 0 and 4°C, with a relative humidity of 65-70%.
It is important to keep onions away from direct sunlight, as this can cause them to sprout prematurely.
It is also important to store onions away from other fruits and vegetables, as they release ethylene gas, which can cause onions to spoil faster.
Onions can be stored in mesh bags, baskets, or crates, which allow for air circulation and prevent moisture build-up.
Maximising Shelf Life
To maximise the shelf life of onions, it is important to inspect them regularly and remove any onions that are starting to sprout or have soft spots.
Onions that are damaged or bruised should also be removed, as they are more susceptible to rot.
Onions can also be stored in the freezer, either chopped or whole. However, it is important to blanch them first to prevent enzymatic reactions that can cause the onions to become bitter.
Onion Usage in Cuisine – Types of Onions in South Africa
As a staple food in South Africa, onions are used in various ways in the country’s cuisine. Here are some of the most popular ways in which onions are used in South African dishes.
Cooking with Onions
Onions are a fundamental ingredient in many cooked dishes in South Africa. They are used as a base for sauces, stews, and soups. Onions are often sautéed or caramelized to bring out their natural sweetness.
Onions are also used in curries, biryanis, and other rice dishes to add flavor and texture. In fact, it is difficult to find a savory South African dish that does not include onions in some form.
Onions in Salads and Raw Dishes
Onions are also used in salads and other raw dishes in South Africa. They are often sliced thinly and added to green salads, potato salads, and coleslaws to provide a sharp, pungent flavor.
Spring onions, also known as scallions, are a popular addition to salads and are often used to garnish dishes. Raw onions are also used in sandwiches, burgers, and hot dogs to add crunch and flavor.
Economic and Market Factors – Types of Onions in South Africa
Demand and Supply
As a popular ingredient in many South African dishes, onions are in high demand across the country. However, the supply of onions can vary depending on the season and weather conditions.
According to a commodity profile report from the Department of Agriculture, Land Reform and Rural Development, onion prices declined by 8.8% in 2019 despite a 2.6% decline in volume supplied at the market. This was due to poor uptake of onions. In 2020, there was a 1.9% decrease in onion volume supplied at the market, resulting in a 20% increase in market price.
On the demand side, onions are a staple ingredient in many South African households and restaurants. As such, the demand for onions is relatively stable throughout the year. However, demand may increase during certain seasons, such as the festive season, when more people are cooking and entertaining.
Onion Farming as a Business
Onion farming can be a profitable business for farmers in South Africa. According to the commodity profile report from the Department of Agriculture, Land Reform and Rural Development, onion farming is one of the most important field crops in the country, with an estimated production of 196,000 tons in 2020.
The report also states that onion farming is a viable business for small-scale farmers, as onions can be grown in small plots of land and have a relatively short growing cycle.
However, onion farming does come with its challenges. One of the biggest challenges is achieving high yields, which can be affected by weather conditions, pests, and diseases. Farmers need to be knowledgeable about the best farming practices and techniques to maximize their yields and profits.
Agricultural Techniques and Innovations – Types of Onions in South Africa
I understand the importance of using the right agricultural techniques and innovations to enhance crop quality and yield. Here are some techniques that I recommend for planting onions:
Seed Trays and Nurse Crops
Using seed trays is an effective way to get your onion seedlings off to a good start. It allows for better control of soil moisture and temperature, which can help with germination and early growth.
Additionally, planting onions alongside nurse crops such as lettuce and tomatoes can help to improve soil quality and reduce the risk of disease.
Disease Resistance and Crop Health
Disease resistance is crucial when it comes to planting onions in South Africa. As such, it is important to choose onion varieties that are resistant to common diseases such as Fusarium, Botrytis, and Downy Mildew.
Proper sanitation practices such as crop rotation, weed control, and removal of infected plants can also help to prevent the spread of disease and improve overall crop health.
