Plant Description:
Streblus anthropophagorum, also known as the "man-eating tree" or "bojaye," is a rare and mysterious plant species that belongs to the family Moraceae. It is native to the tropical rainforests of Madagascar and surrounding islands, but has also been reported in parts of Africa and Asia.
General Appearance:
The man-eating tree can grow up to 18 meters tall, with a thick trunk and a dome-shaped canopy. Its distinctive feature is its large, leathery and dark green leaves that are arranged alternately on the branches. The tree's flowers are small and greenish-yellow, and its fruit is an edible drupe.
Common Names:
The plant is commonly known as the "man-eating tree" or "bojaye" due to its mythical reputation of capturing and killing humans. However, it is also known by other names such as "rat-tree" and "candy tree."
Uses:
The man-eating tree has been the subject of many myths and legends, but there is no scientific evidence to support its ability to eat humans or animals. In fact, it has many uses for humans and wildlife alike. The tree's bark and leaves are used in traditional medicine for their anti-inflammatory and analgesic properties. Its bark is also used to make durable ropes and paper, while the fruit is consumed by local wildlife such as lemurs and bats.
Light Requirements
Streblus anthropophagorum is able to tolerate a range of lighting conditions, including partial shade and full sunlight. However, for optimal growth and development, it requires bright and indirect light.
Temperature Requirements
The plant thrives in warm temperatures, ideally between 20°C and 30°C. It is sensitive to cold temperatures and should be protected from frost. If the temperature falls too low, the plant may experience stunted growth or even die.
Soil Requirements
The plant requires well-draining soil that is rich in organic matter. The ideal soil pH range is from slightly acidic (pH 5.5) to neutral (pH 7.0). Soil that is too alkaline can cause nutrient deficiencies and impair the plant's growth. Streblus anthropophagorum prefers soil that is moist but not waterlogged.
Cultivation Methods
Streblus anthropophagorum is a tropical evergreen tree that is propagated through seeds. It can be cultivated in well-draining sandy loam or clay loam soil with a pH of around 6-7. The tree needs to be planted in an open location with partial shade, away from strong winds that can break the branches. It does not require any special cultivation method or care, but avoiding direct sunlight during afternoon hours can be beneficial.
Watering Needs
Streblus anthropophagorum requires regular watering, especially during the growing season. The tree should be watered deeply but not excessively to avoid waterlogging or root rot. The soil should be kept moist but not waterlogged. During the dry season, mulching around the tree can help retain moisture and keep the soil cooler.
Fertilization
Streblus anthropophagorum benefits from regular fertilization to encourage growth and maintain healthy foliage. A balanced fertilizer with a ratio of N:P:K of 2:1:1 is recommended. Fertilizer should be applied during the growing season at regular intervals of 3-4 months. It is essential to follow the manufacturer's instructions and avoid applying too much fertilizer, which can burn the roots and damage the tree.
Pruning
Streblus anthropophagorum requires minimal pruning; however, occasional pruning is recommended to maintain its shape and remove any damaged or diseased branches. The pruning should be done during the dormant season to avoid damage to the new growth. It is essential to use sterile pruning equipment to prevent the spread of diseases. The tree's sap is known to cause skin irritation, so it is necessary to wear gloves and protective clothing while pruning.
Propagation of Streblus anthropophagorum (Seem.) Corner
Streblus anthropophagorum (Seem.) Corner, commonly known as the cannibal tree, is a species of plant native to tropical forests of Southeast Asia and the Pacific. It can be grown from seeds, cuttings, and air layering.
Seed Propagation
The seeds of Streblus anthropophagorum can be collected from the fruits that ripen in May or June. The seeds should be extracted and cleaned before being sown in a well-draining potting mix. The pots should be kept in a warm and humid environment, and the soil should be kept moist. The seeds usually germinate within 3-4 weeks, and the seedlings can be transplanted into larger pots after they have grown a few leaves.
Cutting Propagation
Streblus anthropophagorum can also be propagated from stem cuttings. Cuttings should be taken from mature stems in the spring or summer and should be about 10-15 cm long. The lower leaves should be removed, and the cuttings should be dipped in rooting hormone powder before being planted in a well-draining potting mix. The pots should be kept in a warm, humid environment, and the soil should be kept moist. Rooting should occur in about 5-6 weeks, and the new plants can be transplanted into larger pots after a few more weeks.
Air Layering Propagation
Air layering is another way to propagate Streblus anthropophagorum. This method involves making a small cut or wound on a mature stem and covering it with moist sphagnum moss. The moss should be wrapped in plastic or aluminum foil to keep it moist. Once roots have formed, the new plant can be cut from the parent and transplanted into a well-draining potting mix.
In conclusion, the cannibal tree can be propagated from seeds, cuttings, and air layering. Each method has its advantages and disadvantages, but with proper care and attention, growers can produce healthy and vigorous plants.
Disease and Pest Management for Streblus anthropophagorum
Streblus anthropophagorum is a hardy and disease-resistant plant, but it can still be affected by certain pests and diseases. Here are some common issues and ways to manage them:
Diseases
Leaf spot: The most common disease affecting Streblus anthropophagorum is leaf spot, which is characterized by yellowish-brown spots on the leaves that eventually turn black. This disease is caused by fungi and can be managed by removing infected leaves and improving air circulation around the plant. Avoid overhead watering as it can spread the disease. Fungicides can also be used as a preventative measure.
Root rot: Overwatering and poor drainage can lead to root rot, a fungal disease that causes the roots to rot and eventually kill the plant. To avoid this, ensure the plant is in well-draining soil and only water it when the soil has dried out. Treat infected plants by removing the damaged roots and replanting in fresh soil.
Pests
Scale insects: These tiny insects attach themselves to the leaves and appear as brown or white bumps. They suck sap from the plant, causing it to weaken and become susceptible to disease. Use insecticidal soap or oil to eliminate the pests or remove them manually with a cotton swab dipped in alcohol.
Aphids: These small insects suck sap from new growth, causing it to curl and deform. They can be controlled by spraying the plant with a strong stream of water or using insecticidal soap or neem oil.
Mealybugs: These white, cottony insects also suck sap from the plant and can be controlled using the same methods as aphids.
With proper care and attention, Streblus anthropophagorum can thrive without succumbing to pests and diseases. Regularly inspect the plant for signs of damage and take action as soon as possible to prevent further harm.
