Cuttings propagation
Vernonia Fraterna can also be propagated through stem cuttings. Take cuttings from an established plant in early spring or fall. Cuttings should be about six inches long and should be taken from the softwood portion of the stem. Prepare a rooting hormone and dip the cuttings into it. Plant the cuttings in a potting mix and keep the soil moist. After four to six weeks, the cuttings should have developed roots and can be transplanted into individual pots or planted in the garden.
Division propagation
Division propagation involves dividing an established plant into smaller sections. It is best done in the spring or fall when the plant is dormant. Dig up the plant and carefully divide it into smaller sections, ensuring that each section has its roots. Transplant the divided sections into individual pots or directly into the garden. Keep the soil moist until the plants are well established.
Overall, Vernonia fraterna is a hardy plant that is easy to propagate. Whether you use seed propagation, cuttings propagation, or division propagation, you can grow Vernonia fraterna in your garden or greenhouse.
