Growth Conditions of Aspalathus divaricata Thunb. subsp. divaricata
Light Requirements: Aspalathus divaricata Thunb. subsp. divaricata thrives in full sun to partial shade. However, it tends to produce more foliage and flowers when grown in full sun. Therefore, it is essential to place the plant where it can receive at least six hours of direct sunlight per day.
Temperature Requirements: This plant is native to South Africa, where it grows in a mild climate. It tolerates a broad range of temperatures, from 10°C (50°F) to 30°C (86°F). However, it is best to keep it in an environment with a temperature range of 20°C (68°F) to 25°C (77°F). Moreover, it is crucial to protect the plant from frost and extreme heat, which can cause damage to the leaves, stems, or root system.
Soil Requirements: Aspalathus divaricata Thunb. subsp. divaricata prefers well-drained soil that is rich in nutrients. It can grow in various soil types, including sandy, loamy, or clay. However, the soil must be slightly acidic, with a pH range of 5.5 to 6.5. When planting, it is essential to add organic matter, such as compost, to the soil to improve its fertility and structure.
Water Requirements: This plant requires moderate watering, especially during the growing season. It prefers soil that is moist but not waterlogged. Over-watering can cause root rot, which can damage the plant. Therefore, it is essential to let the soil dry partially before watering again. During winter, the plant requires less water, and watering should be done only when the soil is dry.
Fertilizer Requirements: Aspalathus divaricata Thunb. subsp. divaricata is a light feeder, and it does not require much fertilizer. However, it is recommended to add a balanced fertilizer, such as 10-10-10 or 20-20-20, every two to three months during the growing season. It is best to avoid fertilizing during the winter season.
Cultivation
Aspalathus divaricata Thunb. subsp. divaricata, commonly known as kruie tee or wild rooibos, is a flowering plant native to South Africa. It is a shrubby plant that grows up to 1.5 meters tall. The plant prefers sunny locations and thrives in well-drained and acidic soils.
The best time to plant Aspalathus divaricata Thunb. subsp. divaricata is in spring or early summer. The plant can be propagated from seeds or cuttings. Seedlings are planted about 50 cm apart, while cuttings need to be planted deeper in the soil to encourage root development.
Watering Needs
Aspalathus divaricata Thunb. subsp. divaricata is drought-tolerant and does not require frequent watering. The plants can survive on rainfall alone, but in drier areas, they may require moderate watering once every two weeks. It is essential to ensure that the soil remains moist, but not water-logged.
Fertilization
Aspalathus divaricata Thunb. subsp. divaricata does not require regular fertilization. However, a light application of organic fertilizer during the growing season can help boost growth. Avoid using high-nitrogen fertilizers, which can result in overly lush foliage and poor flowering.
Pruning
Pruning is not necessarily required for Aspalathus divaricata Thunb. subsp. divaricata. However, if you notice that the plant has become too leggy, Pruning can encourage bushier growth. The best time to prune is just after flowering season. Cut back the branches by about a third of their length. Dead or diseased branches should be removed immediately.
Propagation methods for Aspalathus divaricata Thunb. subsp. divaricata
Aspalathus divaricata Thunb. subsp. divaricata, commonly known as "bush tea," is a woody shrub that is indigenous to South Africa's Western Cape. There are several methods to propagate this plant, including:
Seed propagation
The most common propagation method for Aspalathus divaricata Thunb. subsp. divaricata is through seeds. The plant produces small seeds that are typically sown in the late winter or early spring. These seeds should be sown in well-draining soil and kept moist until they germinate, which usually takes between two and four weeks. Once the seedlings reach a height of about 5 cm, they can be transplanted to their final growing position.
Cuttings
Aspalathus divaricata Thunb. subsp. divaricata can also be propagated through cuttings. Softwood cuttings can be taken in the spring and early summer when the plant is actively growing. Cuttings should be taken from the tips of the stems and should be about 5-10 cm long.
