Cultivation Methods
Terminalia avicennioides is typically grown from seed. The seeds should be planted in well-draining soil in a container or directly in the ground. Sow the seeds about 2-3 cm deep in the soil and make sure to water them right away. In general, it is best to plant the seeds during the rainy season when the soil is moist.
Watering Needs
Terminalia avicennioides requires regular watering, especially during extended dry periods. However, it is important not to overwater the plant because it is sensitive to waterlogging. Waterlogging can cause root rot, which can ultimately kill the plant. It is crucial to let the soil dry out a bit between watering sessions, but make sure the soil does not become too dry.
Fertilization
Terminalia avicennioides can benefit from periodic fertilization. Use a balanced fertilizer that contains nitrogen, phosphorus, and potassium. Apply the fertilizer during the rainy season when the plant is most actively growing. Do not use too much fertilizer, as excessive amounts can cause leaf scorch or even damage the roots.
Pruning
Terminalia avicennioides may require some pruning, especially during the early stages of growth. When the plant is about 2-3 years old, remove the lower branches to encourage a single, straight stem. This will promote the growth of a strong trunk. Additionally, pruning can help control the plant's size and shape and prevent overcrowding. When you prune the plant, always use clean, sharp tools and make clean cuts to avoid damaging the plant.
Propagation of Terminalia avicennioides Guill. & Perr.
Terminalia avicennioides Guill. & Perr., commonly known as Black Terminalia, is a deciduous tree found in West Africa. It is valued for its wood and medicinal properties. The tree has a high demand, and as such, propagating it is essential. The tree can propagate through several methods.
Seed Propagation
The use of seeds is the most common method of propagating Terminalia avicennioides. Seeds can be obtained from the tree during the fruiting period. Seeds can be collected from the ground after falling off the tree or by plucking the fruits from the tree and extracting the seeds. The seeds should be allowed to dry before planting. They should be planted in a well-prepared bed with good soil drainage.
The seedlings should be watered regularly, especially in the first year. After the seedlings have grown for one year, they can be transplanted to their permanent location. The best time to transplant is during the rainy season when the soil is moist. Seedlings should be spaced at an appropriate distance to allow for proper growth and development.
Cuttings Propagation
Another method of propagating Terminalia avicennioides is through cuttings. This method involves taking cuttings from the mother plant and rooting them in appropriate conditions. The cuttings should be taken from the semi-hardwood part of the tree, and the leaves should be removed except for the top two or three.
The cuttings should be dipped in hormone powder to encourage rooting. The cuttings should then be planted in a well-drained medium. They should be covered with a plastic bag to prevent moisture loss and placed in a shaded area. After the cuttings have rooted, they can be transplanted into individual pots or directly into their permanent location.
Air-layering Propagation
Air-layering is a method of propagating Terminalia avicennioides that involves inducing roots on a stem that is still attached to the mother tree. This method is particularly useful for the propagation of mature trees that are not easily propagated through cuttings or seeds.
The process involves wounding the stem of the tree and applying rooting hormone to the wound. A ball of wet soil is then applied to the wounded area and covered with a plastic bag. After rooting has occurred, the newly formed roots can be cut from the mother plant and transplanted into its new location.
Overall, Terminalia avicennioides can be propagated through several methods. The choice of propagation method depends on the availability of resources and the purpose of cultivation.
