Propagation of Hydrocotyle verticillata Thunb.
Hydrocotyle verticillata Thunb., also known as Whorled Pennywort, is a popular aquatic plant in aquariums and water gardens due to its unique appearance and ease of care. Propagation of this plant is quite straightforward and can be done through several methods:
Propagation through Runners
Hydrocotyle verticillata Thunb. propagates naturally through runners, which are horizontal stems that grow from the main plant. These runners typically form new plantlets at the nodes and can be easily separated from the parent plant once they have developed roots of their own. To propagate using runners, simply wait until the plant has formed multiple runners, then detach them from the parent plant and transplant into a new location.
Propagation through Cuttings
Another way to propagate Hydrocotyle verticillata Thunb. is through cuttings. Simply cut off a section of the stem and plant it in a new location. Ensure that the cutting has at least 2-3 leaves and make sure to provide adequate lighting and nutrients for new roots to form.
Propagation through Division
Hydrocotyle verticillata Thunb. can also be propagated through division. This involves separating the plant into smaller sections and replanting each section in a new location. First, remove the plant from its pot and gently tease apart the individual sections. Make sure each section has an adequate amount of roots and replant into new pots or aquatic environments.
Regardless of the propagation method, it's important to provide the new plants with the proper environment. Hydrocotyle verticillata Thunb. prefers moderate to bright light and a nutrient-rich substrate. Additionally, the plant prefers cooler water temperatures between 68-78°F. With proper care, newly propagated plants should flourish and provide a beautiful addition to any aquatic environment.
