Propagation of Clitoria rubiginosa Pers.
Clitoria rubiginosa Pers. can be propagated through seeds or vegetative methods such as stem cuttings.
Propagation through Seeds
Fresh seeds collected from mature plants have the highest chance of germination. To increase the success rate, the seeds are soaked in warm water for about 24 hours before planting. A well-draining potting mix is filled in the planting container, and the seeds are planted about 1 cm deep into the soil. The container is placed in a warm, well-lit area and watered regularly to ensure that the soil stays moist. Germination usually takes about one to two weeks.
Propagation through Stem Cuttings
Stem cuttings from healthy plants taken during the active growth phase can be used for propagation. The cuttings should be about 10-15 cm long with a few healthy leaves attached. The lower leaves are removed, and the cuttings are dipped in rooting hormone before planting them in a well-draining potting mix. The container is placed in a warm, well-lit area and watered regularly to ensure that the soil stays moist. It takes about 2-3 weeks for the cuttings to form roots and start growing.

- Aphids: These are small insects that suck the sap from the leaves of the plant, causing them to curl and distort. To control these pests, the use of insecticidal soap or neem oil can be effective.
- Whiteflies: These are small, flying insects that feed on the leaves of the plant, causing them to yellow and wilt. To control these pests, the use of insecticidal soap or neem oil can be effective.
- Spider Mites: These are tiny pests that suck the sap from the plant, causing leaves to become yellow and then brown. To control these pests, the use of miticides or insecticidal soap can be effective.
Overall, the best way to prevent diseases and pests in Clitoria rubiginosa Pers. is to ensure that the plant is grown in optimal conditions, including well-draining soil, proper watering, and adequate sunlight. Regular monitoring of the plant can help to detect any problems early on, making it easier to manage them effectively.
