Propagation of Vernonia ulophylla O.Hoffm. var. hoffmanniana Hiern
Vernonia ulophylla O.Hoffm. var. hoffmanniana Hiern can be propagated through sexually or asexually. The propagation process varies depending on the method applied.
Propagation through seeds
Propagation of Vernonia ulophylla through seed is the easiest method. Collect mature seed heads and remove the seeds from the individual seed heads. The seeds can be prepared for planting by placing them in warm water for two days. This treatment can help to soften the seed coat and increase germination rates.
The seeds can be sown directly into the soil outdoors once the soil temperature consistently reaches 70°F (21°C). The seeds should be covered with a light layer of soil and should not be buried too deep. This can also be propagated by seed indoors by starting seeds in flats or small containers and transplanting outdoors once it becomes established.
Propagation through cuttings
The propagation of Vernonia ulophylla O.Hoffm. var. hoffmanniana Hiern can also be through cuttings. Hardwood cuttings are taken during winter dormancy period. These can be up to 8 inches (20 cm) in length. The cuttings should be dipped in rooting hormone and then set in a container filled with well-draining soil. The cuttings should be watered regularly and kept in a warm, humid environment. Within weeks, the cuttings will begin to root and start to grow.
The use of cuttings is also favored because it enables the propagation of selected variety.
Disease Management
