Light Requirements
Aspalathus ternata can grow in full sun to partial shade. However, it thrives best in a location that receives full sun in the morning followed by partial shade in the afternoon. It is known to tolerate some shade, but too much shade may result in reduced growth and flower production.
Temperature Requirements
The plant is native to South Africa and can tolerate a wide range of temperatures. It thrives best in a moderate temperature range of about 20 to 25 degrees Celsius during the day and around 10 to 15 degrees Celsius at night. It can, however, survive temperatures ranging from 5 to 35 degrees Celsius.
Soil Requirements
Aspalathus ternata requires porous soils that are well-drained and contain a mixture of sand, silt, and clay. It can grow in soils that have a pH range of 4.5 to 7.5. The plant can grow in sandy soils with low nutrient content and can fix nitrogen from the atmosphere, which makes it well adapted to poor soils. It is also able to grow in acidic soils, which makes it suitable for acidic soil types such as fynbos and heathland.
Cultivation Methods
Aspalathus ternata, commonly known as the Three-leafed Rooibos, is a shrub that is best grown in well-drained soil and a sunny location. It can tolerate average soils but prefers a pH range between 6.0 and 7.0. It is recommended to grow Aspalathus ternata from seeds as it has proven to be more successful than rooting from cuttings. The ideal time to sow seeds is during the early summer season.
Prepare the soil by removing any weeds, rocks, or debris that may hinder growth. Plant the seeds about 2 cm deep in the soil and water them thoroughly. Three-leafed Rooibos can take up to 2 months to germinate, so patience is required.
Once new growth appears, choose the strongest-looking plants and thin out the rest. Plants that are too close to each other will compete for nutrients, and their growth will be stunted.
Watering Needs
Aspalathus ternata requires moderate watering, especially during the growing season and dry periods. It is crucial to establish the root system before reducing water intake. Always ensure that the soil is moist and not waterlogged. Excess water can lead to root rot and cause the plant's death.
During winter, the shrub enters a dormant phase, and watering can be reduced. However, it would be best if you continue to keep the soil moist to prevent complete dryness.
Fertilization
Aspalathus ternata does not require heavy fertilization. Fertilize once a year during the growing season, either in spring or early summer before new growth emerges. Apply a balanced fertilizer, ensuring that it does not come into contact with the plant's leaves or stem.
Pruning
Pruning is essential for maintaining the shrub's shape and enhancing its overall health. The ideal time to prune is during late winter to early spring before the new growth appears. Remove any dead or damaged wood, and cut back the remaining stems to encourage new growth.
Maintenance pruning can also be done during the growing season to ensure the shrub remains in good shape. Avoid pruning too much and always use sharp, clean pruning shears to prevent disease transmission.
Propagation of Aspalathus ternata (Thunb.) Druce
Aspalathus ternata (Thunb.) Druce, commonly known as Lekkerbos or Cape Mountain buchu, is a plant species native to the Cape Floristic Region of South Africa. It is a woody shrub that belongs to the Fabaceae family.
Propagation by Seed
One of the primary methods of propagating Aspalathus ternata is through seed. The seeds should be collected when they are ripe and brown. They are then soaked in warm water for 24 hours to soften the seed coat. Afterward, the seeds are sown in a well-draining potting mix that has been moistened. The seeds should germinate within 3-4 weeks. Once the seedlings have grown to about 5 cm in height, they can be transplanted into individual containers or directly into the ground.
Propagation by Cuttings
Aspalathus ternata can also be propagated by taking cuttings from an established plant. This method is particularly useful when the plant is difficult to grow from seed, or when a gardener wants to maintain specific characteristics of the parent plant. Cuttings can be taken in the early summer or early fall when the stems are semi-hard. The cuttings, which should be approximately 10-15 cm in length, are then dipped in rooting hormone and planted in a well-draining potting mix. Over time, the cuttings should develop roots and can be transplanted into individual containers or directly into the ground.
Propagation by Division
Propagation by division involves separating an established plant into two or more parts, each with its roots. This method is best suited for mature plants that have outgrown their container or are starting to become woody. The plant should be carefully dug up, and the roots should be gently separated. Each section can then be planted in its container or in the ground. Care should be taken to keep the soil damp until new growth appears.
Regardless of the propagation method used, it is essential to provide the young plants with adequate water and sunlight. Aspalathus ternata prefers a well-draining soil that is slightly acidic. With proper care, this beautiful shrub will grow and thrive for many years to come.
