Propagation of Thespesia rogersii S.Moore
Thespesia rogersii S.Moore, commonly known as beach hibiscus, is a beautiful plant that belongs to the family of Malvaceae. The plant is native to Fiji, Vanuatu, and Samoa and is known for its vibrant, large flowers that bloom in shades of pink, white, and yellow. Propagating Thespesia rogersii S.Moore can be done through different methods, including:
Seed Propagation
The most common method of propagating Thespesia rogersii S.Moore is through seed propagation. The seeds can be collected from the plant during the flowering season. Make sure the seeds are soaked in water for up to six hours before planting. Sow the seeds in a well-draining soil mix and keep the soil moist. The germination of the seeds may take up to two weeks. Once the seedlings are strong enough to be transplanted, they can be shifted to bigger pots or planted in the ground.
Cuttings Propagation
Another method of propagating Thespesia rogersii S.Moore is through cuttings. Take cuttings that are about six inches long from the plant's new growth and remove the lower leaves. Dip the cuttings in rooting hormone powder and plant them in well-draining soil mix. The cuttings should be kept moist and in a warm, lighted area. The propagation of Thespesia rogersii S.Moore through cuttings may take up to four weeks, after which the cuttings can be transplanted to bigger pots.
Air layering Propagation
Air layering is a less commonly used method of propagating Thespesia rogersii S.Moore. This method involves making a small cut in the stem of the plant and applying rooting hormone powder to the cut. Then, wrap a small amount of moist sphagnum moss around the cut and cover with plastic wrap to secure it in place. The roots will start to grow within a few weeks. Once the roots have established, the new plant can be separated from the parent plant and transplanted to a bigger pot or planted in the ground.
