Propagation of Cyrtandra longifolia var. wahiawae Rock
Cyrtandra longifolia (Wawra) Hbd. ex C.B. Clarke var. wahiawae Rock is a beautiful plant known for its elongated, shiny leaves and gorgeous pinkish-purple flowers. Propagation of this plant can be done through several methods including:
Seed Propagation
The easiest and most common method of propagation for Cyrtandra longifolia var. wahiawae Rock is through seeds. Once the fruit ripens, it will split open and release the seeds. These seeds will need to be harvested and cleaned before sowing. Ensure that the soil mixture is moistened before planting the seeds, and place them around 1-2 cm below the soil surface. The seeds can be covered with plastic or a clear plastic bag to retain moisture. Ensure that the soil stays moist, and the seeds should germinate within 2-3 weeks.
Stem Cuttings Propagation
Propagation can be done through stem cuttings, where cuttings can be taken from the parent plant and then rooted in the soil. Cuttings should be taken in the spring during the active growing season when the plant has fresh growth. Ensure that the cutting has at least two sets of leaves and remove the lower set of leaves before rooting. Dip the cuttings in a rooting hormone and place the cutting in well-draining soil mix. You can place a plastic bag or a clear plastic cover over the cutting to encourage rooting. After 2-3 weeks, roots should start to develop, and the plastic can be removed.
Air Layering Propagation
Air layering is a propagation technique where a branch is wounded and then wrapped to promote root growth where it was wounded. In this method, a groove around the branch of the plant is made and wrapped in plastic with some rooting hormone. After 4-6 weeks, roots should start to form around the wounded area. Cut the rooted branch below the wound and plant in a pot with well-draining soil mix. Water and drain as per usual and keep the pot in a warm and humid location until the plant is established in the pot.
Propagation of Cyrtandra longifolia var. wahiawae Rock should be done in the active growing season (spring or summer) when the plant is in optimal condition. With proper care, this plant can be propagated easily through any of the methods described above.
