Stem cuttings propagation involves taking cuttings from a mature plant and rooting them in soil to produce new plants. Thunbergia schimbensis plants can also be propagated through stem cuttings. Follow these steps:
- Select a healthy, mature stem from the parent plant
- Make a cutting about 4-6 inches long, ensuring it has a few leaves attached to it
- Remove any leaves that are closest to the cutting's base
- Dip the cut end in rooting hormone powder and plant it in a potting mix
- Place the pot in bright, indirect sunlight and keep the soil moist
- Rooting should take place within two to three weeks, and once the new plant is established, it can be transplanted into a larger container or directly into the garden soil
Propagation of Thunbergia schimbensis S.Moore can be done by either seed or stem cutting methods. It is essential to follow the correct procedures for successful propagation. Whatever propagation method you choose, ensure that you do not damage the parent plant in the process.
