Propagation of Tricalysia crepiniana De Wild. & T.Durand Plant
Tricalysia crepiniana De Wild. & T.Durand is a tropical plant species from Central Africa which belongs to the family, Rubiaceae. It is a small, evergreen shrub that has medicinal properties. It is used to treat various health problems like headache, asthma, and hypertension. Here are some of the propagation methods of Tricalysia crepiniana:
Seeds
The most commonly used propagation method for Tricalysia crepiniana is through seeds. The seeds are collected from the dry fruits of the plant. After collecting the seeds, they should be cleaned and treated with a fungicide to prevent any fungal diseases. The seeds can be directly planted in the soil or in a seedling tray with well-draining soil. After planting, they should be watered regularly and kept in a warm and moist environment. Germination usually takes around 4 to 6 weeks.
Cuttings
Another propagation method for Tricalysia crepiniana is through stem cuttings. The stem cuttings should be taken from a healthy and mature plant. The cuttings should be around 6 inches long and should have a few leaves attached to them. After taking the cuttings, the leaves should be removed from the lower half of the stem. The cuttings should be planted in a well-draining soil mixture and watered regularly. The cuttings should be kept in a warm and humid environment to facilitate root growth. Rooting usually takes around 4 weeks.
Air Layering
Air layering is another propagation method that can be used for Tricalysia crepiniana. In air layering, a part of an established plant is covered with soil or rooting mixture to promote rooting. The plant should be healthy and have branches that are flexible and bendable. A small section of bark is removed from the stem and rooting hormone is applied. The section is then wrapped in moist sphagnum moss and covered with plastic wrap to keep moisture in place. After some weeks, roots should begin to form. The rooted stem can be cut off from the parent plant and transplanted into a pot or directly into the ground.
