Growing Rooibos: A Guide for Small Farmers in the Cederberg

Rooibos, South Africa’s iconic herbal tea, has become a symbol of the Cederberg region, both culturally and economically. With increasing global demand for natural and caffeine-free teas, many small-scale farmers in the Cederberg are considering rooibos cultivation as a sustainable farming venture. If you’re one of them, here’s a practical guide on how to successfully grow rooibos and tap into this thriving industry.

Understanding the Rooibos Plant and Its Natural Habitat

Rooibos (Aspalathus linearis) is a leguminous shrub that thrives naturally in the sandy soils and Mediterranean climate of the Cederberg and surrounding areas of the Western Cape. The plant’s deep taproot system makes it drought-tolerant, an essential trait given the region’s hot, dry summers and cool, wet winters.

For small farmers, growing rooibos means working in harmony with the environment, as the crop is highly adapted to local conditions and doesn’t perform well outside its natural range.

Soil Preparation and Site Selection

Rooibos prefers well-drained, acidic sandy soils with low nutrient content. Soil pH should ideally range between 4.5 and 6.0. Avoid areas with clay-rich or waterlogged soils, as rooibos roots are prone to rot.

Choose a site with good sun exposure and minimal frost risk. Slopes are often ideal as they improve drainage and reduce the risk of standing water.

Before planting, farmers should clear the land of weeds and loosen the topsoil to promote root penetration. Some farmers also use light tilling to improve soil aeration.

Propagation and Planting

Rooibos can be grown from seed or seedlings. However, most small farmers prefer direct seeding due to cost-effectiveness.

Rooibos seeds have a hard coat and require a process called scarification to improve germination. Traditionally, farmers have used boiling water or mechanical abrasion to weaken the seed coat before planting.

Plant seeds in autumn (April to May), allowing young seedlings to establish during the cool, wet winter months. Row spacing typically ranges from 50 cm to 1 meter, allowing enough room for bushes to mature.

Managing Growth and Weeding

Weed control is crucial during the first year when rooibos plants are still small and vulnerable. Manual weeding or mulching with organic materials can help reduce weed pressure without relying on chemical herbicides.

Rooibos is a low-maintenance crop once established, requiring minimal inputs. Thanks to its natural nitrogen-fixing abilities, it enriches the soil with nutrients, reducing the need for additional fertilisers.

Irrigation Needs

While rooibos is drought-tolerant, young seedlings may benefit from supplemental watering during extended dry spells in their first year. However, overwatering can lead to root diseases, so soil moisture levels should be monitored carefully.

Established rooibos plants generally survive on rainfall alone, making the crop well-suited for low-input, dryland farming.

Pest and Disease Management

The Cederberg’s dry climate helps limit many common crop diseases. However, farmers should watch for signs of:

• Root rot (due to poor drainage)
• Aphid infestations (can be managed naturally or with organic solutions)
• Damping-off in seedlings (caused by soil-borne fungi)

Practicing crop rotation and maintaining good field hygiene can go a long way in preventing serious outbreaks.

Harvesting Rooibos

Rooibos plants are typically ready for their first harvest after 18 months to 2 years. Harvesting is done during the summer months (January to March) when the plants are most leafy.

Using sickles or mechanical cutters, farmers cut the top 30-40 cm of the plant. The harvested material is then chopped, bruised, and left to ferment and dry in the sun—a process that gives rooibos its distinctive reddish-brown colour and rich flavour.

Processing and Marketing

Small-scale farmers often deliver their harvested rooibos to local processing facilities, where it’s cleaned, graded, and packaged for domestic sale or export.

With growing international demand for organic and sustainably farmed products, certification such as Organic, Fairtrade, or Rainforest Alliance can add significant market value. Farmers interested in these markets should start the certification process early.

Diversifying Income with Rooibos

Besides supplying bulk rooibos for tea production, small farmers can explore value-added products like:

• Rooibos skincare products
• Herbal infusions mixed with other local botanicals
• Rooibos iced teas and specialty drinks

These products can open new revenue streams, especially for farmers with access to local markets, online sales, or eco-tourism outlets.

• Join a local rooibos farmers’ cooperative for support, market access, and training opportunities.
• Monitor weather patterns and soil conditions carefully, as climate plays a big role in rooibos yield.
• Keep detailed farm records to track growth cycles and identify areas for improvement.

With careful planning and commitment, small farmers in the Cederberg can turn rooibos cultivation into a profitable and sustainable agricultural business.
