Cutting Propagation
Vernonia bainesii Oliv. & Hiern subsp. wildii (Merxm.) Wild can be easily propagated through cuttings. Cuttings are best taken from mature plants in early spring when plant growth is most active. The cuttings should be about six inches long and should be taken from healthy branches. The lower leaves should be removed, and the cutting should be planted in a well-draining potting mix. The cutting should be kept in a warm, humid environment, and roots usually form within three weeks.
Division Propagation
Another method of propagating Vernonia bainesii Oliv. & Hiern subsp. wildii (Merxm.) Wild is through division. The plant can be divided in early spring when the plant growth is most active. The plant should be carefully lifted from the ground, and the root system should be divided into several clumps. Each clump should have at least one healthy shoot and a good root system. The divided clumps should be planted in a well-draining potting mix and kept in a warm, humid environment until new growth appears.
Propagation of Vernonia bainesii Oliv. & Hiern subsp. wildii (Merxm.) Wild is relatively easy and can be done with minimal effort. With proper care, the plant can reach its full maturity within a year and provide beautiful blooms.
Disease and Pest Management for Vernonia bainesii Oliv. & Hiern subsp. wildii (Merxm.) Wild
