Propagation of Rohria sulcata Thunb.
Rohria sulcata Thunb., commonly known as "chimmoni" or "Indian navvy", is a flowering plant with numerous medicinal properties. It is native to India but has been introduced in other parts of the world due to its popularity.
Propagation by Seeds
The most common method of propagation for Rohria sulcata Thunb. is through seeds. The plant produces small-sized seeds that can easily be collected from the matured fruit. The seeds should be sown in the soil, which should be moist and well-drained. The best time to sow the seeds is during the rainy season.
Once the seeds have been sown, they should be covered with a thin layer of soil and kept moist. Germination should occur within 2-3 weeks. The seedlings should be transplanted to individual pots after they have grown 1-2 inches tall.
Propagation by Cuttings
Another method of propagation for Rohria sulcata Thunb. is through stem cuttings. The cuttings should be taken from mature plants and should be around 10-12 inches long. The cutting should not be too woody or too soft, but rather semi-hardwood.
The bottom part of the stem cutting should be dipped in rooting hormone powder, and then it should be planted in a well-draining potting mix. The cutting should be kept in a shady area and kept moist. The roots should form within 2-4 weeks, and the cutting can be transplanted to a bigger pot or in the ground.
Propagation by Layering
