Dead or damaged branches should be removed promptly to prevent the spread of disease. It is also important to remove any branches that are crossing or rubbing against each other, as this can cause damage or injury to the plant.

Propagation of Hunteria hexaloba (Pichon) Omino

Hunteria hexaloba (Pichon) Omino, commonly known as African cherry or False cubeb, is a tropical tree species that belongs to the family Apocynaceae. The plant is native to West and Central Africa and is heavily exploited for its valuable timber, fruits, and medicinal properties. Propagation of Hunteria hexaloba can be done through various methods, including:

Seed propagation

Seeds are the most common way of propagating Hunteria hexaloba. The plant produces large, pointed-shaped seeds that are found in a woody, green to brown fruit. The fruit is usually oblong or elliptical in shape, and each contains between one to six seeds. Before planting, seeds should be removed from the fruit and washed to remove any pulp or debris. Stratification or soaking in water for several days can be done to enhance germination. Sow seeds in a well-drained potting mixture or directly in the final planting site. Germination typically occurs within three to four weeks, and success rates of up to 80% have been reported.

Air layering

Air layering is a propagation method in which roots are stimulated to grow on a section of a stem while it is still attached to the parent plant. To air layer Hunteria hexaloba, select a healthy, mature stem and make a 1 cm deep cut in the bark. Apply rooting hormone on the wounded area, wrap it with a moist sphagnum moss, and cover the moss with a plastic film. Secure the moss by tying it with a string or a tape. After several weeks, roots will emerge from the wound, and the stem can be cut off and planted as a new plant.

Cuttings propagation

Propagation by cuttings is another method of propagating Hunteria hexaloba. Cuttings should be taken from mature stems, preferably during the early stages of the rainy season when the plant is actively growing. Cuttings should measure between 15-20 cm in length, and all leaves should be removed except for the top one or two. The base of the cutting should be dipped in rooting hormone and planted in well-drained soil or a potting mixture. The cuttings should be kept moist but not waterlogged and placed in a shaded area until roots form. Success rates of up to 70% have been reported using this method.
