Origin
Terminalia baumannii Engl. & Diels, also known as simply Terminalia baumannii, is a medicinal plant belonging to the family Combretaceae. It is native to the tropical and subtropical regions of Africa, particularly in countries such as Cameroon, Kenya, Tanzania, Uganda, and Zimbabwe.
Common Names
The plant is commonly called "Muiri" and "Mueri" in Kenya, "Mpofu" in Zimbabwe, "Mutewa" in Tanzania, and "Kongoloti" in Cameroon.
Uses
The different parts of the Terminalia baumannii plant have long been used in traditional medicine for various purposes. The bark is used for treating gastrointestinal disorders, respiratory ailments, and skin infections. The roots are boiled and the water is ingested as treatment for diarrhea. The leaves are used for wound healing, as well as for treating malaria and fever. The fruits, on the other hand, are edible and can be consumed raw or cooked.

General Appearance
Terminalia baumannii is a small to medium-sized deciduous tree that can grow up to 10 meters tall. Its bark is grayish-brown and rough, while its leaves are elliptical, oblong, and arranged alternately on the branches. The flowers are small and inconspicuous, with a greenish-yellow color. The fruit is a drupe that is green when young and turns to yellow or brown when mature. It has a single seed enclosed in a hard, woody shell.
The tree is generally hardy and adaptable, able to grow well in a wide range of soil types. It is often found growing naturally in savannas, woodlands, and dry forests.
Growth Conditions of Terminalia baumannii Engl. & Diels
Terminalia baumannii Engl. & Diels, also known as the almond tree, is a tropical evergreen tree that is widely distributed in Africa, southern Asia, and Australia. It is mainly found in woodland and savannah areas, often near watercourses. The tree grows up to 20 meters tall and may live for several hundred years.
Light Requirements
The almond tree prefers full sunlight and can tolerate partial shade. It is not well-suited to grow in areas with heavy shade as it may lead to slow growth and poor fruiting.
Temperature Range
Terminalia baumannii grows best in warm to hot climates. It is adapted to tropical and subtropical regions with average temperatures ranging from 10 to 35°C. The tree can tolerate brief periods of frost but may suffer in prolonged cold temperatures.
Soil Requirements
The almond tree can grow in a broad range of soil types, including loamy, sandy, and clayey soils. The soil should be well-drained and slightly acidic or neutral. It can tolerate periodic flooding for short periods but will not thrive in water-logged soils.
The almond tree can grow in nutritionally poor soils but may benefit from the application of organic fertilizers, particularly during the first few years of growth. It may also benefit from mulching to reduce weed competition, retain moisture, and improve soil structure.
Thus, the optimal growth conditions for Terminalia baumannii are full sunlight, warm to hot temperatures, and well-drained, slightly acidic or neutral soil.
Cultivation methods for Terminalia baumannii Engl. & Diels
Terminalia baumannii Engl. & Diels, commonly known as the sandpaper tree, is native to Africa and thrives well in tropical and subtropical regions. For cultivation, it is best to plant this tree in an area with well-drained soil and full sunlight exposure. It is a hardy tree that can tolerate a wide range of soils, including sandy, loam, and clay soils.
The plant propagation can be done using seeds or stem cuttings. However, stem cuttings offer a quicker way to propagate the plant than using seeds.
Watering needs for Terminalia baumannii Engl. & Diels
Terminalia baumannii Engl. & Diels is drought-tolerant and can survive with minimal watering once established. However, the plant requires regular watering during the establishment period, especially when grown in hot and dry regions. A rule of thumb is to water the plant deeply once a week and increase the frequency during the dry months.
It is essential to avoid waterlogging the tree since it does not tolerate wet soils. Soggy soil can lead to root rot and cause the death of the plant.
Fertilization of Terminalia baumannii Engl. & Diels
Terminalia baumannii Engl. & Diels does not require extensive fertilization. A balanced fertilizer application once a year, preferably during the growing season, can provide the necessary nutrients needed to support plant growth and development. An organic fertilizer is ideal, as it is gentle on the plant, and it has a slow-release functionality that promotes consistent growth over time.
Pruning Terminalia baumannii Engl. & Diels
Pruning Terminalia baumannii Engl. & Diels is not necessary, but it can be done to maintain the desired shape and size. The ideal time to prune the plant is during the dormant season, mainly in late winter or early spring. When pruning, it is essential to use sterilized and sharp tools to prevent the spread of disease.
Propagation of Terminalia baumannii
Terminalia baumannii, commonly known as Ethiopian almond, is a slow-growing deciduous tree that is commonly propagated by seed and cuttings.
Seed propagation
Seeds of Terminalia baumannii are collected from mature fruits and are sown in a nursery bed or container with well-draining soil. The seeds should be treated with hot water to break seed dormancy before sowing. Once sown, the seeds need to be watered regularly to maintain a moist environment. Germination of the seeds usually takes 4 to 6 weeks.
Cutting propagation
Terminalia baumannii can also be propagated by stem cuttings. Stem cuttings with a length of at least 20 cm and a diameter of 1 cm are collected from healthy, disease-free mother plants during the rainy season. The cuttings are dipped in rooting hormone and planted in a mixture of sand and soil in a well-drained container. The container should be kept under shade and should be watered regularly. It takes about 2 to 3 months for the cuttings to form roots and begin to grow.
Propagation of Terminalia baumannii through seed and cutting results in plants with the same genetic makeup of the mother plant. It is recommended to use healthy and disease-free planting material to ensure a successful propagation.
Disease and Pest Management of Terminalia baumannii Engl & Diels Plant
Terminalia baumannii Engl. & Diels is a sturdy plant that is native to Africa. However, like other plants, it is not immune to diseases and pests that can cause damage to its growth and productivity. Good disease and pest management practices can help to ensure healthy growth and bountiful yields of the plant.
Common Diseases
Fungal diseases and bacterial infections are the most common diseases in Terminalia baumannii plants. These are mainly caused by wet conditions, overwatering, or poor ventilation. Some common diseases that can affect the plant are:
- Leaf Spot: This is characterized by black or brown spots on leaves which eventually lead to leaf drop. It is caused by fungal infections. To manage it, remove infected leaves, avoid over-watering, and apply copper-based fungicides.
- Anthracnose: This is characterized by dark, sunken circular spots on leaves, flowers, and fruits. It is caused by fungi and can be managed by pruning infected parts, improving ventilation, and applying copper fungicides.
- Powdery Mildew: This is characterized by a white, powdery coating on leaves and stems. It is caused by fungi and can be managed by applying neem oil, sulfur-based fungicides, and ensuring adequate spacing between plants for air circulation.
Common Pests
Terminalia baumannii plants are susceptible to pest infestation, which can cause damage to the plant. Here are some common pests that can affect the plant and ways to manage them:
- Spider Mites: These are tiny bugs that feed on plant sap, causing leaves to appear stippled or yellowed. To manage them, remove affected plants and apply insecticidal soap or neem oil.
- Mealybugs: These are small whitish bugs that produce a waxy substance on leaves and stems. They can weaken plants and spread viruses. To manage, remove infected plants and apply insecticidal soap or neem oil.
- Aphids: These are small insects that suck sap from the plant's leaves, leading to stunted growth and curled leaves. To manage them, spray the plant with soapy water or neem oil.
It is important to regularly monitor the plants for signs of diseases or pest infestation. Prevention is key, so always maintain good plant hygiene by removing diseased plants or infested plant debris and applying preventative measures such as natural or chemical pest control methods. These practices will go a long way in ensuring healthy growth and productivity of Terminalia baumannii plants.
