The plant can grow up to 3 meters high and bears blue flowers that eventually turn into berries. In this section, we will discuss the different methods of propagating this plant.
Seed Propagation
One of the most common methods of propagating Solanum indicum L. subsp. distichum (Schumach. & Thonn.) Bitter is through seeds. The seeds are usually collected from mature fruits and require special attention when sowing as they have low viability rates. After collecting the seeds, they should be cleaned and stored in a cool, dry place until ready for sowing. To germinate the seeds, they should be sown in a well-draining soil mix and kept moist. It is important to keep the seeds in a warm and sunny location for optimal growth.
Stem Cuttings Propagation
Another method of propagating Solanum indicum L. subsp. distichum (Schumach. & Thonn.) Bitter is through stem cuttings. This method involves taking a small section of the stem from the parent plant and rooting it in a well-draining soil mix. The cutting should be taken from a healthy and disease-free plant and should be around 10-15cm long. The leaves from the lower half should be removed, and the cutting should be dipped in rooting hormone before planting. The planted cutting should be kept moist and located in a warm location with indirect sunlight until roots develop.
Air-Layering Propagation
Air-layering is a propagation method that involves wounding the stem of the parent plant and wrapping it with moist soil or sphagnum moss to stimulate root growth. This method works well for plants that have difficulty rooting from stem cuttings, such as Solanum indicum L. subsp. distichum (Schumach. & Thonn.) Bitter. To air-layer, the stem of the parent plant should be selected, and a small section of bark removed. Next, the wound should be covered with moist soil or sphagnum moss and wrapped with plastic. The wrapped section should be checked regularly for root formation. Once roots develop, the section can be cut from the parent plant and planted in a well-draining soil mix.
Overall, Solanum indicum L. subsp. distichum (Schumach. & Thonn.) Bitter can be propagated through various methods. The method chosen will depend on the preference and experience of the gardener. Seed propagation is the easiest and most suitable for beginners, but stem cuttings and air-layering can be used for more advanced gardeners looking to produce multiple plants quickly.
