Propagation of Voacanga eketensis Wernham
Voacanga eketensis Wernham, commonly known as the Pink Voacanga or Nigerian Dream Herb, is an evergreen shrub that originates from West Africa. The plant is popular for its high medicinal, ornamental, and spiritual importance. Propagation of the plant can be done by several methods such as:
Seed propagation
The easiest way to propagate Voacanga eketensis Wernham is through seeds. Seeds of the plant can be obtained from the matured fruits. The seeds should be cleaned, dried, and stored in a cool dry place before planting. The seeds should be sown in well-draining soil or seed-raising mix, and covered with a thin layer of soil. The soil should be kept moist; germination of the seeds usually takes around 2-4 weeks. After germination, the seedlings can be transplanted into individual pots, and grown to maturity.
Cuttings propagation
Propagation of Voacanga eketensis Wernham can also be done through stem cuttings. The cuttings should be taken from mature healthy plants, and should be around 10-15cm long. The leaves of the lower half of the cutting should be removed, and the cutting dipped in rooting hormone. The cuttings can be placed in a potting mix, and kept moist. Roots will start to grow in around 3-4 weeks. Once well-rooted, the cuttings can be transplanted into individual pots.
Air layering propagation
Propagation of Voacanga eketensis Wernham can also be done through air layering. This method involves stripping a portion of bark from the stem, and applying rooting hormone. The exposed area is then wrapped with a moistened sphagnum moss, and covered with a plastic wrap to enhance humidity. Roots will start growing in around 2-4 weeks. Once roots have developed, the newly formed plant can be separated from the mother plant, and transplanted.
In conclusion, Voacanga eketensis Wernham can be propagated through seeds, cuttings, and air layering. These methods are simple and can be easily accomplished with basic gardening tools. Regardless of the method used, it’s important to provide adequate care and attention, ensuring the plants' optimal growth conditions.
Disease and Pest Management for Voacanga eketensis Wernham
Voacanga eketensis Wernham is a tropical tree that grows in the forests of West and Central Africa.

Here are some common diseases and pests that affect the plant and ways to manage them.
Common Diseases
One of the most common diseases that affect Voacanga eketensis is leaf spot. This is a fungal disease that causes circular or irregular spots on the leaves, which may turn yellow or brown as the disease progresses. Leaf spot can weaken the plant and make it more susceptible to other diseases. To manage leaf spot, it is important to remove infected leaves and stems and dispose of them properly. Fungicides may also be used to prevent the spread of the disease.
Another disease that affects Voacanga eketensis is powdery mildew. This is a fungal disease that appears as a white or grayish powdery film on the leaves and stems. Powdery mildew can be prevented by ensuring that the plant is growing in well-drained soil and has good air circulation. If the disease is detected, a fungicide may be used to manage it.
Common Pests
One of the most common pests that affect Voacanga eketensis is mealybugs. These are small insects that appear as white, fluffy masses on the leaves and stems. Mealybugs feed on the sap of the plant and can cause wilting and yellowing of the leaves. To manage mealybugs, it is important to remove infected leaves and stems and dispose of them properly. Insecticides may also be used to prevent the spread of the pest.
Another pest that affects Voacanga eketensis is scale insects. These are small, brown insects that attach themselves to the leaves and stems and suck the sap from the plant. Scale insects can be managed by manually removing them from the plant with a soft cloth or by using an insecticide.
By being aware of these common diseases and pests and taking steps to manage them, it is possible to ensure that Voacanga eketensis grows strong and healthy.
