Propagation of Senecio petiolaris DC.
Senecio petiolaris, commonly known as the thread senecio, is a popular plant for its thin, trailing stems and delicate green leaves. It is easy to propagate and can be done through several methods such as stem cuttings, division, and seed propagation.
Stem Cuttings
Stem cuttings are the most common method of propagation for Senecio petiolaris. Take a healthy stem from the parent plant and make a clean cut below a leaf node. Cuttings should be approximately 3-4 inches long. Remove the bottom leaves and dip the cut end in rooting hormone. Place in a well-draining soil mix and keep moist. Keep in a warm, bright location to encourage rooting. Roots should form within a few weeks and the new plant can be transplanted into its own container.
Division
Senecio petiolaris can also be propagated through division. This method is best done during the plant's active growth period, which is typically in the spring and summer. Carefully dig up the plant and separate it into smaller sections, making sure each section has a healthy root system. Repot each section into a well-draining soil mix and keep moist. Place in a warm, bright location to encourage growth.
Seed Propagation
Seed propagation is another option for propagating Senecio petiolaris. Collect seeds from the plant when the flowers have dried and turned brown. Sow seeds thinly on the surface of a well-draining soil mix and keep moist. Cover the tray with plastic wrap or a humidity dome to retain moisture. Seeds should germinate within two to four weeks. Once the seedlings have developed several sets of leaves, they can be transplanted into their own container.
