Propagation of Cynanchum arboreum Forssk.
Cynanchum arboreum Forssk., commonly known as the tree swallowwort, is a dioecious plant from the family Apocynaceae. Propagation of this plant is possible through various methods including seeds, cuttings, and layering.
Propagation through Seeds
The most common method of propagating Cynanchum arboreum is through seeds. The seeds should be collected when they reach maturity and have turned brown. After collecting, the seeds should be sowed in a well-drained potting mix and kept in a warm and humid environment. Once the seeds have germinated, they should be transplanted into individual pots and allowed to grow until they are big enough for transplantation.
Propagation through Cuttings
Cynanchum arboreum can also be propagated through stem cuttings. The cuttings should be taken from the mature, woody stems of the plant in early spring. The cuttings should be approximately 4-6 inches long and taken from healthy plants. Once the cuttings are taken, they should be dipped in rooting hormone and planted in a well-draining potting mix. The pot should be kept in a humid environment until the cuttings have rooted and are ready to be transplanted.
Propagation through Layering
In layering, a stem of the plant is bent and buried in soil. The buried portion of the stem should be stripped of its leaves except for the tip. The stem should be secured in place using a wire or wooden peg. After some weeks, the stem will start producing new roots and shoots. Once new roots have grown, the stem can be separated from the mother plant and planted in a separate container.
Overall, Cynanchum arboreum Forssk. can be propagated through various methods including seeds, cuttings, and layering. Growers can choose the method that suits them best and ensure they follow best practices for success.
