Propagation of Bidens robustior S.Moore
Bidens robustior S.Moore, commonly known as the Congo tickseed or Robust beggarticks, is a flowering plant species native to East Africa.
The plant can be propagated by both sexual and asexual methods.
Sexual Propagation
Bidens robustior can be propagated by seed. The flower head of the plant produces viable seeds that can germinate into new plants.
Collect seeds from the flower head when they are mature and dry. The seeds can then be sown in a well-draining potting mix.
It is best to cover the seeds with a thin layer of potting mix and keep moist. Place the container in a warm location and provide bright light. Germination should occur within a few weeks.
Asexual Propagation
Bidens robustior can also be propagated by stem cuttings. Take stem cuttings from the plant during the growing season.
Make a clean cut at an angle just below a node and remove any lower leaves. Dip the cut end of the stem in rooting hormone before placing in a well-draining potting mix.
Keep the cuttings moist and in a warm location with bright, indirect light. Roots should begin to form in a few weeks.
Once roots have formed, the newly propagated plants can be repotted into individual containers.
Propagation of Bidens robustior S.Moore is relatively easy, and the plant is often used in mixed borders, herbaceous beds, or containers.
