Propagation of Bidens asymmetrica (Levl.) Sherff
Bidens asymmetrica (Levl.) Sherff, commonly known as Hairy Beggarticks, is a perennial herbaceous plant that belongs to the family Asteraceae. It is native to North America. The plant grows up to 4 feet tall and produces bright yellow flowers from summer to fall. The plant is propagated by seeds, stem cuttings, and division.
Propagation by Seeds
Seeds of Bidens asymmetrica are usually available in the market, or you can collect them from mature plants. It would help if you sowed the seeds in early spring after the last frost. Soak the seeds in water for 24 hours before sowing them. You can plant them directly into the soil or use a seed-starting tray. Cover the seeds with a thin layer of soil and keep the soil moist until germination, which usually takes 14-21 days. Once the seedlings have emerged, thin them out to ensure enough spacing for mature plants. The plants will flower in the second growing season.
Propagation by Stem Cuttings
The stem cuttings method is ideal for Bidens asymmetrica that is mature and healthy. Take a 4-inch cutting from the tip of the stem and remove the leaves from the bottom. Dip the cut end in rooting hormone powder, and plant it in a pot with well-draining soil. Water the cuttings regularly and keep them in a warm and bright place but avoid direct sunlight. Within a few weeks, the cutting will start developing roots, and new leaves will emerge. You can then transplant them to their permanent location in the garden or container.
Propagation by Division
Propagation by division is the easiest method if the parent plant is mature and healthy. You can divide the plant in early spring or late fall. Dig up the plant and divide it into sections using a sharp and sterile knife. Each section should have roots, shoots, and buds. Plant each section in a pot or directly in the garden bed, water well, and keep the soil moist until the plant establishes itself.
