Antiaris africana Engl.
Antiaris africana Engl. is a dioecious evergreen tree that belongs to the Moraceae family. This species is native to tropical and subtropical areas of Africa, ranging from Senegal to Uganda and Tanzania. The tree is commonly known as the African breadfruit, false breadfruit, or the corkwood tree.
Appearance
The African breadfruit tree can grow up to 35 meters tall with a trunk diameter of up to one meter. It has a straight stem that is covered with a rough, corky bark, which is where its common name "corkwood tree" is derived. The leaves are pale green, coriaceous, and leathery, with an oblong to elliptical shape. The tree produces small, greenish flowers that are clustered together in panicles.
After pollination, the female tree produces large, globular fruits that resemble breadfruit, hence the name "African breadfruit." The fruits have a rough, greenish-brown skin that becomes smooth when fully ripe and yellow. The fruit contains many small seeds that are surrounded by a white, starchy pulp.
Uses
Antiaris africana Engl. has long been used for various purposes. The bark, roots, and leaves have been used in traditional medicine to treat a variety of ailments, including fever, coughs, and malaria.
The fruit of the tree, which is rich in carbohydrates, has been used as a food source by many African communities. The seeds of the African breadfruit are also edible. They are often roasted and then ground into a fine flour or used as a coffee substitute.
In addition to its medicinal and food uses, the corkwood tree is also used in the production of timber. The wood is hard and durable, making it suitable for furniture, flooring, and other construction purposes. The bark is also used to produce a fibrous material that is used in the making of ropes and mats.
Despite its many uses, Antiaris africana Eng. is not widely cultivated, and its populations are declining due to deforestation and habitat loss.

Antiaris africana Engl. grows well in areas with high light intensity. However, it can also survive in partially shaded areas. It is recommended that the plant receives at least six hours of direct sunlight daily.
Temperature Requirements:
Antiaris africana Engl. is native to humid tropical regions. The plant grows well in temperatures ranging from 20°C to 35°C. Temperatures below 5°C are detrimental, and the plant may not survive prolonged exposure.
Soil Requirements:
The soil should be well-drained, rich in organic matter, and slightly acidic. Antiaris africana Engl. grows well in soils that are loamy, sandy, or clayey. However, the soil should not be waterlogged for prolonged periods as it may lead to root rot.
Cultivation methods for Antiaris africana Engl.
Antiaris africana Engl. is a tropical plant that grows best in warm, humid environments. It requires well-draining soil that is rich in organic matter with a pH ranging from 6.0 to 7.0. The plant prefers full sunlight but can tolerate partial shade. It is essential to provide enough space for the plant to grow since it can reach up to 60 feet in height.
If you plan to grow Antiaris africana, you'll need to purchase seeds or saplings from a reputable vendor. This plant prefers a warm, humid climate with temperatures ranging from 68 to 86°F (20 to 30°C). It grows best in a sheltered location but can withstand some wind if adequately protected.
Watering needs for Antiaris africana Engl.
Proper watering is essential when growing Antiaris africana. This plant requires regular watering in the growing season but is susceptible to root rot if the soil remains too wet. It is necessary to let the soil dry out slightly between waterings, but never allow it to become completely dry. During the dormant season, you should reduce watering.
When watering, focus on the plant's root zone and avoid getting water on the leaves, as this can lead to fungal disease. Use room temperature water and try to keep the soil evenly moist but not waterlogged.
Fertilization for Antiaris africana Engl.
Antiaris africana Engl. benefits from regular fertilization during the growing season. A high-nitrogen fertilizer can be used every two to four weeks, but be sure to follow the manufacturer's instructions. Fertilizer should be applied to the outer edge of the plant's drip line, where most of the feeder roots are located. It is essential to avoid getting fertilizer directly on the trunk, as this can lead to damage.
If the plant is leafier than expected, you might need to reduce the amount of fertilizer you are using. Alternatively, if the plant is failing to grow and develop foliage, it may need more fertilizer.
Pruning Antiaris africana Engl.
To keep Antiaris africana Engl. healthy and looking its best, it is essential to practice proper pruning. Ideally, you should prune the plant during the dormant season, just before the growing season begins. A simple shaping prune of the canopy should suffice, and it's important to remove any dead or diseased wood. If the plant has grown too tall, it's vital to cut off the top to a desirable height.
When pruning your Antiaris africana, always use sharp, clean blades to avoid introducing any pathogens. If you notice that the foliage is wilting or the bark is splitting, or if the plant has stopped growing entirely, it is recommended to seek advice from an arborist.
Propagation of Antiaris africana Engl.
Antiaris africana Engl., also known as the African sapwood or false iroko, is a large deciduous tree that can grow up to 45 m tall. It has valuable wood, medicinal properties, and economic importance. The plant can be propagated by various methods depending on environmental conditions and desired results.
Seed propagation
Antiaris africana produces seeds in a large fruit that can contain up to 300 seeds. Seed propagation is the most common and easiest way to propagate the plant. The seeds should be collected when the fruit is ripe, and the pulp removed. The seeds should then be soaked in warm water for 24 hours, and drained before planting in well-draining soil. The soil should be kept moist and placed in a warm and sunny location. The seedlings should emerge in 2-4 weeks, and should be transplanted to larger pots or in outdoor areas after they develop at least two leaves.
Air-layering propagation
Air-layering is another method of propagation for Antiaris africana. It requires a mature stem which is selected and wounded by removing a ring of bark or superficial tissue. The wounded segment is then treated with a rooting hormone, and wrapped in moist sphagnum moss before being covered with black polythene to create a humid rooting environment. Roots should appear within 6-8 weeks. Once there are roots, you can cut the rooted segment from the parent plant and plant it in a pot or in the ground.
Cuttings propagation
Cuttings is another method of propagation for Antiaris africana. It involves taking semi-hardwood cuttings from the parent plant, and using a rooting hormone at the bottom. The cutting should then be planted in well-draining soil and kept moist. If successful, new roots and leaves should emerge after 4-6 weeks. The plant should be transplanted to a pot or in the ground once it develops enough foliage.
Disease Management for Antiaris Africana
Antiaris Africana is usually resistant to pests and diseases, making it an excellent option for commercial agriculture. However, under some circumstances, some problems can arise, depending on the region and environmental conditions. One of the most effective strategies for managing diseases on Antiaris Africana is prevention.
The following are some of the common diseases that might affect Antiaris Africana:
- Anthracnose: It is a fungal disease that affects the leaves, stem, and fruit of the tree primarily. It starts as small, light spots and eventually grows larger to create a larger sunken area on the plant. To prevent Anthracnose, always cut off and dispose of any infected parts of the plant as soon as you see them. Proper sanitation can help prevent the spread of the disease between plants.
- Powdery Mildew: This is a fungal disease that appears as a white or grey powdery film on the surface of the leaf. It can be caused by high humidity and overcrowding of plants. The best way to manage powdery mildew is to ensure proper air circulation around the plant by pruning or spacing out plants. Regularly spray with fungicides to protect the tree from powdery mildew.
- Leaf Spot: This is a fungal disease that causes yellowish-brown or black spots on the leaves of the tree. The leaves eventually fall from the tree if it's not treated. The best way to prevent leaf spot disease is by managing the moisture level of the soil. Avoid watering the plant from above, watering only the base of the plant. Fungicides can also be applied as a preventative measure.
Pest Management for Antiaris Africana
The following are some of the common pests that might affect Antiaris Africana:
- Aphids: These are small insects that feed on the sap of plants. They are usually found on the underside of leaves, and their presence can cause distorted growth and the yellowing of leaves. To manage aphids, spray the leaves with water to knock them off the plant. You also can apply natural or chemical insecticides to protect the tree.
- Termites: They feed on the bark and wood of the tree, which can cause the tree to die if they inflict a lot of damage. To manage termites on Antiaris Africana, ensure that all the trees around it are free from infestation. Termites could come in through rotten or damaged wood, so pay attention to that. Chemical treatments are highly effective in preventing termite infestation.
- Caterpillars: They feed on the leaves of the plant and could damage a whole tree in a short amount of time. Apply natural or chemical insecticides to protect the tree. Also, remove any damaged or infected branches and dispose of them properly away from the tree.
By managing pests and diseases on Antiaris Africana through preventive measures and effective treatment, the tree would remain healthy, and it would yield a bountiful harvest.
