The flowers are small and white and appear in clusters during the summer season. The fruit of the tree is a small, round berry that turns yellow when ripe.
Uses of Boscia pruinosa Chiov.
Boscia pruinosa Chiov. has many traditional uses in sub-Saharan Africa. The tree's bark, roots, and leaves are used in traditional medicine to treat a range of ailments such as diarrhea, stomach ache, and fever. The fruit of the tree is edible and is used to make a refreshing drink. The wood of the African corkwood is hard and durable and is used to make furniture, tool handles, and other household items.
Boscia pruinosa Chiov. is also an important tree for the environment as it provides shade and shelter for animals and birds. Its roots help to stabilize the soil and prevent erosion.
Light Requirements
Boscia pruinosa Chiov. typically grows in areas with plenty of sunlight. Thus, it requires full sun or partial shade to grow. It can tolerate some shade, but it won't thrive in low light conditions.
Temperature Requirements
Boscia pruinosa Chiov. is suited for subtropical and tropical climates. It can withstand high temperatures up to 45°C during the summer months. However, it cannot handle frost or chill temperatures below around 10°C. The plant requires warm tropical temperatures year-round for optimal growth.
Soil Requirements
Boscia pruinosa Chiov. grows well in well-draining soils that are slightly acidic to neutral with a pH level ranging from 6.0 to 7.0. The plant prefers sandy loam or loam soils that are rich, fertile, and well-draining. Its roots cannot handle soils that are waterlogged or heavy clay soils, as they can cause root rot. The addition of organic matter such as compost, manure, or peat moss can improve soil fertility and drainage.
Cultivation methods
Boscia pruinosa Chiov. thrives in areas with warm temperatures, high humidity, and well-draining soil. The plant can handle some level of drought but prefers consistent moisture in the soil. It is advisable to plant the shrub in full sun or partially shaded areas to ensure optimal growth. The ideal pH range of the soil should be between 6.0 to 7.5 to provide the necessary nutrients for growth.
Watering needs
Boscia pruinosa Chiov. requires moderate watering. Irrigate the plant at least once a week in dry seasons or when the soil seems dry. The rate of watering should reduce in the rainy seasons to avoid overwatering. Overwatering leads to waterlogging, which may cause the roots to rot. It is advisable to use a watering can or drip irrigation to irrigate the shrub and minimize water wastage.
Fertilization
The Boscia pruinosa Chiov. plant requires regular fertilization to provide the necessary nutrients for growth and development. Fertilize the plant once every month using a balanced fertilizer that contains nitrogen, phosphorus, and potassium in equal proportions. Use organic fertilizers for better results and avoid over-fertilization, which may lead to nutrient toxicity and damage the plant.
Pruning
Boscia pruinosa Chiov. requires little pruning, mainly to remove dead and diseased branches. Prune the plant during the dormant season (winter) to promote new growth in the spring. Use sanitized equipment to minimize the chances of infecting the plant with diseases or pests. Do not over-prune the shrub as it may reduce its flowering and fruiting capabilities.
Propagation of Boscia pruinosa Chiov.
Boscia pruinosa Chiov., commonly known as the African shepherd tree, is a slow-growing evergreen tree that belongs to the family Capparaceae. Propagation of this plant can be done through various methods such as seed germination, stem cuttings, and air layering.
Propagation by Seed Germination
Seed propagation is the easiest and most common method of propagation for Boscia pruinosa Chiov. The seeds should be collected from fully matured trees and sown during the beginning of the rainy season. The seeds should be soaked in water for at least 24 hours, and then sown in a well-drained medium. The seedlings must be adequately watered and kept in a partially shaded area for the first few weeks until they become established.
Propagation by Stem Cuttings
Boscia pruinosa Chiov. can also be propagated through stem cuttings. Select a healthy stem from the parent plant and take a cutting approximately 15cm long. The leaves on the lower end of the stem should be removed and the stem should be treated with a rooting hormone to increase the chances of successful rooting. The cutting can be inserted into a rooting medium and placed in a humid environment. It should be watered regularly and covered with a plastic bag to maintain moisture levels until it develops roots.
Propagation by Air Layering
Air layering is a suitable method for propagating Boscia pruinosa Chiov. from mature branches. An incision is made on a mature branch and a rooting hormone is applied to the exposed section. The incised section is wrapped in damp sphagnum moss, and covered with a plastic wrap. The moss should be kept damp regularly and roots will develop at the incision point. Once the roots have formed, the branch can be severed and potted in a well-drained medium.
Disease Management
Boscia pruinosa Chiov. is generally a tough and resilient plant but is still susceptible to various diseases. Here are some common diseases that might affect the plant:
- Anthracnose: This fungal disease affects the leaves of the plant causing yellowing, browning, and necrosis of the leaves. To manage anthracnose, plants should be sprayed with a fungicide. Copper-based fungicides are usually effective against this disease.
- Crown rot: Crown rot is a fungal disease that affects the stem of the plant, causing it to decay. To manage crown rot, the affected plants should be removed and destroyed, and the soil should be treated with a fungicide. The soil should be allowed to dry out before planting new plants.
- Leaf spot: This disease is caused by a fungal or bacterial infection that causes small, circular spots on the leaves of the plant. To manage leaf spot, affected leaves should be removed and destroyed. The plant should be sprayed with a fungicide to prevent further infection.
Pest Management
Boscia pruinosa Chiov. is susceptible to various pests, which can damage the leaves, stem, and fruits of the plant. Here are some common pests that might affect the plant:
- Scale insects: These insects are tiny and can be difficult to spot. They attack the stems and leaves of the plant, sucking the sap of the plant, which can cause the plant to weaken and die. To manage scale insects, affected plants should be sprayed with an insecticide. Neem oil is a good natural remedy to control scale insects.
- Spider mites: These are common pests on Boscia pruinosa Chiov. They attack the leaves of the plant, causing yellow spots on the leaves. The plant can also become deformed and stunted in growth. To manage spider mites, affected plants should be sprayed with an insecticide. Insecticidal soap, neem oil, and pyrethrin are all effective in controlling spider mites.
- Fruit fly: These pests can damage the fruit of the plant, causing it to deteriorate rapidly. To manage fruit flies, affected fruit should be removed and destroyed. The remaining fruit can be protected by using sticky traps or a fruit fly bait. Covering the fruit with a fine mesh can also protect it from fruit fly damage.
