It is commonly known as the monkey orange due to its fruit that is similar in appearance to an orange but with a hard, yellow shell that looks like a monkey's face. Strychnos mitis S.Moore is native to tropical and subtropical Africa, including countries such as Kenya, Tanzania, Mozambique, and South Africa.
Appearance of Strychnos mitis S.Moore
The tree of Strychnos mitis S.Moore can grow up to 20 meters tall and bears dark green, glossy leaves that are smooth and oval-shaped. Its flowers are small and yellowish-green in color, and the fruit is spherical and can reach up to 20cm in diameter. The fruit has a hard, woody shell that contains a white, fibrous pulp that is edible.
Uses of Strychnos mitis S.Moore
The fruit of Strychnos mitis S.Moore is edible and is consumed by humans and animals alike. The pulp of the fruit is used to make juice, jams, and jellies in some parts of Africa. The bark and roots of the tree are used in traditional medicine to treat various ailments such as malaria, fever, and stomach problems. The seeds of Strychnos mitis S.Moore are also used to make soap while the tough, fibrous inner bark can be made into cords and ropes.
In addition to its practical uses, Strychnos mitis S.Moore is also a popular ornamental plant in some regions due to its attractive, glossy leaves and unique fruit. It is often cultivated as a shade tree and is an important part of the ecosystem as it provides food and shelter for many species of animals.
Light Requirements
Strychnos mitis S.Moore requires a considerable amount of sunlight to thrive. It typically grows in regions that receive abundant sunlight throughout the year. Therefore, it is essential to expose the plant to light to ensure maximum growth and development.
Temperature Requirements
The plant requires moderate temperatures to grow. It is typically found in regions that experience warm to hot temperatures throughout the year. Temperatures ranging from 20°C to 30°C are optimal for its growth and development. However, the plant can survive in temperatures as low as 10°C, but lower temperatures can stunt its growth.
Soil Requirements
Strychnos mitis S.Moore grows best in well-draining soils that are rich in organic matter. The plant requires a slightly acidic to neutral soil pH, ranging from 5.5 to 7.5, to ensure optimal growth. The soil should be moist but not waterlogged. The plant cannot tolerate waterlogged soils, which can lead to root rot and eventually plant death.
Cultivation Methods
Strychnos mitis, also known as the monkey orange, is a small to medium-sized tree that can grow to a height of up to 18 meters. It is native to the humid, tropical regions of Africa and is often found in secondary forests, open woodlands, and along riverbanks.
If you are planning to cultivate Strychnos mitis, it is best to plant it in well-drained sandy or loam soils that are rich in organic matter. The plant requires full to partial sun exposure, with at least 6 hours of direct sunlight daily. Monkey orange seedlings or cuttings can be planted in the field or containers and transplanted once they have developed strong roots.
Watering Needs
Proper watering is crucial in the cultivation of monkey orange. While it can tolerate drought conditions, regular watering is necessary to ensure optimal growth, especially during the early years. Newly planted seedlings require more water to establish roots and grow. When mature, water your Strychnos mitis tree deeply once or twice a week to keep the soil moist, but not water-logged.
Fertilization
Monkey orange trees respond well to organic fertilizers such as compost and manure, which add nutrients to the soil, including nitrogen, phosphorus, and potassium. Fertilize your plants once or twice a year, during the rainy and dry seasons to enhance growth and fruit production. Avoid applying too much fertilizer, as this may lead to salt accumulation and harm the plant.
Pruning
Pruning helps to shape and maintain your Strychnos mitis tree, reduce pest and disease infestation, and promote good air circulation. Prune your plant during the dry season when the tree is dormant. Remove any dead, weak, or damaged branches and suckers. Thin out the canopy to reduce shading and encourage light penetration. Be sure to use clean, sharp tools and avoid damaging the bark.
Propagation of Strychnos mitis S.Moore
Strychnos mitis S.Moore can be propagated through various methods:
Seeds
The most common propagation method for Strychnos mitis S.Moore is through seeds. The collected seeds must be planted immediately after harvesting since they have a short viability period. To improve germination rates, the seeds should be soaked in warm water for 24-48 hours before planting. The planting medium should be soil-based and well-draining, and the seeds should be sown at a depth of about 1 cm.
Cuttings
Another propagation method that can be used for Strychnos mitis S.Moore is through stem cuttings. The cuttings should be taken from semi-hardwood stems, and the length should be between 10-15 cm. The lower leaves should be stripped, and the cuttings should be dipped in rooting hormone before planting. The planting medium should be a mixture of sand and peat, and the cuttings should be planted at a depth of about 3-4 cm. The cuttings need to be kept in a warm and humid environment until rooting occurs.
Air-layering
Strychnos mitis S.Moore can also be propagated by air-layering. This method involves creating a wound on a mature stem and covering it with a rooting medium, such as sphagnum moss. Once roots have formed, the new plant can be cut free from the parent plant and potted in a well-draining soil mix.
Grafting
Grafting is another propagation method that can be used for Strychnos mitis S.Moore. The plant is usually grafted onto a rootstock of a related species to improve its growth rate, disease resistance, or adaptability to different soil types. Grafting requires considerable skill and is usually done by experienced propagators.
Disease and Pest Management of Strychnos mitis S.Moore
Strychnos mitis S.Moore is a tropical plant species found in Africa. It is commonly known as the monkey orange due to its yellow-orange fruit that is eaten by primates and humans. However, like any other plant species, S. mitis is susceptible to diseases and pests that can negatively affect its growth and productivity. Therefore, it is crucial to understand the common diseases and pests that might affect S. mitis and how to manage them.
Common Diseases
One of the common diseases that affect S. mitis is anthracnose, which is caused by a fungus called Colletotrichum gloeosporioides. Anthracnose causes black spots on the leaves and stems of the plant, which can lead to defoliation and stunted growth. To manage anthracnose, it is essential to ensure proper drainage, reduce overhead irrigation, and prune infected branches to prevent the spread of the disease.
S. mitis is also susceptible to leaf spot, which is caused by a fungus called Cercospora strychni. Leaf spot causes circular spots on the leaves, which can lead to defoliation and reduced photosynthesis. To manage leaf spot, it is essential to remove infected leaves and ensure proper sanitation by disposing of the infected plant material.
Common Pests
One of the common pests that affect S. mitis is mealybugs, which are small, white, and oval-shaped insects that feed on sap from the plant. Mealybugs can cause yellowing of the leaves, stunted growth, and plant wilting. To manage mealybugs, it is essential to maintain proper sanitation by removing infected plant material, using insecticides, and introducing natural predators such as ladybugs and lacewings.
S. mitis is also susceptible to stem borers, which are insects that bore into the stem and feed on the plant's internal tissues, leading to stem damage and reduced plant growth. To manage stem borers, it is essential to prune infected stems, use insecticides, and maintain proper sanitation by removing infected plant material.
In conclusion, S. mitis is susceptible to various diseases and pests that can negatively affect its growth and productivity. Therefore, it is essential to understand the common diseases and pests that might affect S. mitis and how to manage them to ensure optimal plant growth and productivity.
