Propagation of Psychotria williamsii Hutch. & Dalziel
Psychotria williamsii Hutch. & Dalziel, commonly known as Williams' coffee plant, is a flowering shrub native to West Africa. The plant is highly valued for its medicinal properties and is also used for ornamental purposes. Propagation of this plant is done through several methods, including:
Seed Propagation
The most common method of propagating Psychotria williamsii is through seeds. The seeds must be collected from the ripe fruit and planted in well-draining soil. It is important to keep the soil moist but not wet. The seeds should sprout within two to three weeks, but it may take longer in cooler temperatures. It is recommended to plant the seeds in the early spring or late fall.
Stem Cutting Propagation
Another method of propagation is through stem cuttings. Cut the stem from the mother plant at a length of about 8-10 cm and remove the lower leaves and part of the top leaves. Dip the stem cuttings in rooting hormone and plant them in well-draining soil with a ratio of 1:1 of soil and sand. Keep moist but not wet. Within four to six weeks, roots should begin to form and new growth should emerge.
Air Layering Propagation
Propagation can also be done through air layering. Select a healthy stem that is not flowering and make a small cut where the bark and the cambium meet. Wrap wet sphagnum moss around the wounded area and cover it with plastic wrap. Secure both ends with string or twist ties. The moss should remain moist, and after four to six weeks, roots should form. Cut the stem below the roots and plant it in well-draining soil.
Regardless of the propagation method used, it is important to keep the newly propagated plants in a partially shaded area until they have established a strong root system. Once the root system is well established, they can be moved into full sun.
