Maintaining a temperature of 18-25°C during germination is recommended.
Watering Needs
When it comes to watering, it is important to keep the soil consistently moist, especially during the growing season. Allow the soil to dry slightly between waterings, but do not let it completely dry out. Overwatering can lead to root rot, so it is important to ensure proper drainage.

Propagation of Thunbergia alata Bojer ex Sims var. vixalata Burkill
Thunbergia alata Bojer ex Sims var. vixalata Burkill, commonly known as Black-eyed Susan vine, is a stunning plant with vibrant yellow flowers that bloom plentifully. Propagating this plant is an easy task, and there are several propagation methods that can be employed:
Seed propagation
Black-eyed Susan vine produces seeds that can be collected and used for propagation. The seeds are small, black, and oval-shaped. They can easily be collected by allowing the matured seedpod to dry on the vine until it turns brown and starts to split. The seeds can then be collected from the pod and stored in a dry and dark location until they are ready for planting. The best time to sow the seeds is during the spring season when the temperature is between 20°C and 25°C. The seeds should be sown in a well-draining soil mix. After sowing, they should be watered and covered with a plastic wrap to create a humid environment. Germination of the seeds will occur within a week or two, and once the seedlings have 2-3 true leaves, they can be transplanted into individual pots.
Stem cuttings
Stem cuttings can be taken from the Black-eyed Susan vine and used for propagation. This method is most effective during the summer season when the plant is actively growing. To take a stem cutting, select a healthy stem that is at least 10cm long and has several leaves. Using a sharp and sterilized blade, make a clean cut just below a leaf node. Remove all the leaves from the lower half of the stem and dip it in rooting hormone powder. Then plant the stem in a well-draining soil mix and water it immediately. Keep the soil moist, and the cutting should root in 2-3 weeks.
Layering
Layering is another propagation method that can be used for the Black-eyed Susan vine. This method is simple and involves creating a new plant from the parent plant without interrupting its growth. To do this, select a low-growing stem that is still attached to the parent plant. Bury the stem in a shallow hole and secure it to the ground using a wire or a stone. Then, cover the stem with soil and water it regularly. Once new roots have developed from the buried stem, the stem can be cut away from the parent plant and transplanted to a new location.
Propagation of the Black-eyed Susan vine is an easy and fulfilling task that ensures a constant supply of new plants. With these methods, anyone can propagate this plant and enjoy its spectacular blooms.
