However, the pH level of the soil should be between 6.0 to 7.5. The plant also requires regular watering, but the soil should not be waterlogged, as this can cause root rot and other fungal diseases.
Cultivation Methods
The Jamesbrittenia zuurbergensis Hilliard plant is native to South Africa and is commonly referred to as the Eastern Cape jamesbrittenia. It thrives best in a well-drained soil with plenty of organic matter. The optimal temperature range for cultivating this plant is between 40°F and 80°F, and it requires at least 6 hours of sunlight per day. During the growing season, it is important to ensure that the soil is well-watered but not waterlogged.
Watering Needs
The watering needs of the Jamesbrittenia zuurbergensis Hilliard plant will vary depending on the growing conditions. During the active growth period, the plant should be watered thoroughly, but not so much as to cause standing water. Once the plant has become established, it can be watered deeply, but less frequently. Be sure to check the moisture level of the soil before watering and adjust as needed to prevent over or under-watering.
Fertilization

Pruning
The Jamesbrittenia zuurbergensis Hilliard plant requires minimal pruning but can be trimmed back to encourage bushier growth and maintain a more compact appearance. Pruning in the early spring, just before the growing season begins, is advised. Remove any dead or yellowing leaves, as well as any stems that appear to be weak or damaged. Pruning the tips of the stems will encourage the plant to develop a fuller shape.
Propagation of Jamesbrittenia zuurbergensis Hilliard
Jamesbrittenia zuurbergensis Hilliard is propagated from seeds or by taking cuttings from mature plants in the spring or summer.
