Propagation of Hydrocotyle glabrata
Hydrocotyle glabrata is a perennial aquatic plant that belongs to the family Araliaceae. This plant is easy to propagate. It can be propagated through seeds, cuttings, and division.
Propagation through Seeds
Propagation through seeds is the most common and preferred method for Hydrocotyle glabrata. The plant produces small, greenish-white flowers that develop into tiny, dry fruits that contain a single seed each. These seeds can be collected once they are mature, dried, and stored in a dry and cool place. The seeds can be sowed outdoors during spring or in a greenhouse at any time of the year. Covering the seeds with a thin layer of soil and keeping the soil moist will encourage germination. Germination typically occurs within two to three weeks.
Propagation through Cuttings
Propagation through cuttings is also an easy method that can be employed for Hydrocotyle glabrata. Cut a section of the stem that is about 3-4 inches long, and plant it in the substrate. The substrate should be kept moist during the rooting process, which may take several weeks. Once the cutting has developed roots, it can be transplanted into an appropriate container or pond.
Propagation through Division
Propagation through division can also be used for Hydrocotyle glabrata. This method involves dividing the plant into smaller sections and replanting them. Spring is the best time to divide the plant before it begins to grow. Use sharp scissors or a knife to separate the rhizomes and plant them separately in appropriate containers or pond.
Regardless of the propagation method used, it is crucial to ensure that the newly propagated Hydrocotyle glabrata is kept in a suitable environment. The substrate should be kept moist, and exposure to direct sunlight should be minimized until the plant is adequately established.
