Potato farming in South Africa is a dynamic industry influenced by diverse regional climates, seasonal shifts, and the growing impact of climate change. Farmers must adapt their practices to these evolving conditions to ensure high yields and sustainability, advises Walter Matshidi, potato producer and regional chairperson for Potatoes SA.
He provides valuable insights into managing the complexities of potato farming in South Africa, drawn from over ten years of experience in potato production.
Timing is everything
One of the most critical aspects of potato farming is understanding the planting schedule. However, there is no universal planting period for South Africa due to the country’s varied climates.
“There is no ideal planting time that covers the whole of South Africa. Every province has their own times, depending on their climate. If we say, giving an example of Limpopo, it’s late February until mid-August. That’s when you expect to get a better yield,” Mathidi explains.
Farmers must align their planting schedules with regional climate patterns to optimise their yields.
Assess the climate
With the effects of climate change becoming increasingly evident, traditional farming methods are no longer sufficient. Mathidi explains that planting without foreknowledge of the climatic conditions is a risk that will pose challenges for a farmer.
“With the current climate condition, it is very difficult to just plant using [traditional] methods. [Therefore], we check the weather and climate and see what we can plant and when.”
Farmers must monitor weather forecasts and assess climatic trends before deciding on planting times.

Select the right varieties
Potato varieties play a pivotal role in successful farming, as certain types thrive in specific seasons and regions.
“There are varieties that are suited for specific seasons and also for specific areas. You can get this easily from seed growers. That’s where you will get that information. There are always new varieties that are being developed,” Mathidi says.
Consulting with seed growers is essential for accessing the latest information and selecting certified seeds tailored to local conditions.
Have contingency plans for extreme weather
Extreme weather can significantly impact planting times and crop health.
“The extremes of any temperature can affect your planting time. When it’s too hot, it won’t be good. When there’s lots of rain, the seed can rot in the ground,” says Mathidi.
Farmers must be prepared to adjust their planting strategies based on prevailing weather conditions. This may include planting less, waiting for favourable conditions, or preparing land well in advance.
The importance of preparation
Preparation is the cornerstone of successful potato farming.
“For you to be able to have a crop that establishes well, land preparation, enough water and relevant fertilisers, are important,” he says.
Mathidi shares the following key steps for preparation:
- Land preparation: Ensure the soil is well-prepared for planting.
- Water management: Secure adequate water supply for irrigation.
- Fertiliser use: Apply relevant fertilisers based on soil needs.
- Pest control: Address potential pest issues proactively.
Adapting to uncertainty
Flexibility is crucial in dealing with climate unpredictability.
Farmers should remain vigilant and responsive to environmental changes, leveraging tools like weather forecasts to make informed decisions.
“You calculate the time, you listen to weather forecasts, you also pay attention to the climate and its impact. Once you have done this, then you decide when to plant and how much to plant,” says Mathidi.
