Light Requirements
The Cape stenostelma requires full sunlight exposure to thrive. Therefore, growers should provide the plant with at least six hours of direct sunlight per day. When growing the plant indoors, place it in a south-facing window that receives the maximum amount of sunlight possible.
Temperature Requirements
The plant thrives in warm temperatures, with an optimal range of 20°C to 30°C. Therefore, growers should maintain a temperature range between 20°C and 30°C for the plant to grow well. The Cape stenostelma is sensitive to frost and cannot withstand freezing temperatures. Therefore, it is not suitable for outdoor cultivation in areas with cold winters.
Soil Requirements
The plant requires well-draining soil that is not too rich in organic matter. A sandy or gritty soil mix works well for the Cape stenostelma. Growers can add perlite or sand to regular potting soil to improve drainage. The plant is not tolerant of heavy, waterlogged soils, which can cause root rot.
Cultivation Methods

The plant requires a warm, sunny location and well-draining soil. It thrives in sandy loam soil with a pH of 6.5 to 7.5. Plant the seeds after the last frost. The seedlings should appear in about three to five weeks.
Watering Needs
Stenostelma capense Schltr. is drought tolerant and can survive long periods without water. However, it is best to give it a good drink of water once a week during the hot summer months. Ensure the soil is moist but not soaked. When watering, avoid getting water on the leaves and stem.
Fertilization
Stenostelma capense Schltr. does not require much fertilization. However, you can apply a slow-release fertilizer every three to four months to encourage healthy growth. Alternatively, you can use organic compost in the planting hole, which will release nutrients into the soil as the plant grows.
