Propagation of Cynanchum aphyllum auct.
Cynanchum aphyllum auct., commonly known as Dog Strangling Vine, is a plant that can be propagated through several methods.
Seeds
The easiest and most common way to propagate Dog Strangling Vine is through its seeds. The seeds have a high germination rate and can be collected from mature pods, which typically appear after the flowering season. The collected seeds can be directly sown into the soil or started indoors and later transplanted. Seeds need to be kept in warm and moist conditions until they germinate. Generally, germination takes 2-3 weeks.
Cuttings
Propagation from cuttings is not as common for Cynanchum aphyllum auct. However, it still remains a viable option. Cuttings from the plant's stem can be taken during the growing season. The cutting should be about 6-8 inches long and should include a couple of leaves. The cutting needs to be planted in well-drained soil and kept consistently moist until it forms roots. It is advisable to use rooting hormones to increase the chances of success.
Division
Cynanchum aphyllum auct. can also be propagated through division. This is done when the plant has grown to a considerable size. The plant is dug out of the ground and the roots are divided into sections with at least one shoot. Each section is then replanted in well-drained, nutrient-rich soil. It is important to keep the soil consistently moist until the plant establishes in its new location.
Overall, propagating Cynanchum aphyllum auct. is relatively easy and can be done through seeds, cuttings, or division. It is important to keep in mind that the plant is considered invasive in some regions and, therefore, its propagation should be done with caution.
