After initial losses, Reneylwe and Lerato Selialia implemented financial management, developed a crop rotation plan, and expanded sales channels, including supermarkets and regional fresh produce markets. In this episode of 'Farmer's Mentor,' they share their experience and key lessons.
For Reneylwe Selialia, creating the Kopana Holdings agribusiness was a process of learning, networking, and practical application of knowledge. Starting with potato cultivation in 2025, Selialia and her husband Lerato expanded the range to include spinach, onions, and sweet potatoes.
The couple produces vegetables in Randfontein, Gauteng, where they established connections with other farmers, utilizing their experience and knowledge to strengthen their operations. Selialia believes that one of the most important lessons for novice farmers is to acknowledge their knowledge gaps and actively seek information from those around them.
She notes: 'We had to move a little and just grab any knowledge we could get from everyone around us.'
Before starting production, the couple conducted soil tests to study their plot. The results showed that the soil was generally suitable, but the high potassium level required adjusting the nutrient balance before planting.
Water resource management also became a critical aspect. Prolonged drought periods forced them to significantly increase investments in irrigation, and equipment problems taught them practical lessons.
This experience prompted the couple to consider ways to protect crops from weather disasters, including plans to install structures for more controlled growing conditions.
One of Selialia's main lessons is that producing a harvest is only part of running a successful farm. Farmers need to build relationships with potential buyers and understand where their products will be sold.
After the first potato harvest, the couple supplied products to two markets, but a significant amount of potatoes remained. Some of the product spoiled, and some was saved as seeds for the next cycle.
Since then, they have focused on expanding their market presence, approaching various markets in Johannesburg, Vaal, and Rustenburg, while also exploring opportunities to collaborate with supermarkets. Their network of contacts played a central role here: a connection with someone who previously sold produce at the market helped the couple register at the Vaal market and introduced them to a wider distribution system.
Selialia says: 'Because we started asking the right questions and talking to people, we learned that we could expand to other markets.'
For farmers supplying products to markets, Selialia emphasizes that production planning must go beyond the current harvest. She explains: 'It's literally crop rotation. As soon as you harvest, you should already be planting the next crop.'
Since crop maturation takes two to three months depending on the type of crop, careful planning of successive plantings is necessary to ensure a stable supply.
Understanding the financial side of farming has also become an important part of the learning process. They hired an accountant to understand cash flow and calculate real production costs. This allowed them to discover that their first potato harvest was produced at a loss.
Selialia points out that expenses such as seeds, travel, and tolls are easily overlooked when farmers focus primarily on production and sales. Now, the couple uses this information to determine minimum selling prices and create budgets for trips to different markets.
Selialia's advice to young farmers who may feel overwhelmed by the amount of material to study is simple: start, but be humble. She recommends: 'Get started, but start humbly.'
She urges new farmers not to rely solely on online research and technology, but to interact with people who have practical experience and remain open to learning from various sources. 'Human interaction is very important. Learn from people.'
For Selialia and her husband, the long-term goal is to turn Kopana Holdings into a farm enterprise that can be passed down to future generations. 'It's less about us and more about the legacy,' she concludes.
