The plant is also commonly referred to as bitterwood or bonewood. It was named after the Belgian botanist Vanderyst, who first discovered the species in 1905.
General Appearance
The Strychnos vanderystii De Wild. plant is a small tree that typically grows up to 6-8 meters tall. The trunk is straight and cylindrical, with a diameter of 15-25 cm. The bark is grey to brown in color, with a distinctive bitter taste. The leaves are ovate to elliptic, shiny green, and measure about 12-20 cm long and 5-10 cm wide. They are alternately arranged on the branches and have a pointed tip, with a smooth margin.
The flowers are white to pale yellow, small, and tubular in shape. They have a sweet fragrance and are arranged in axillary clusters. The fruit is a globose berry, which is about 5-7 cm in diameter, with an orange to red color when fully ripe. The fruit contains several seeds, which are hard and black in color.
Uses
Strychnos vanderystii De Wild. has been used traditionally for medicinal purposes. The bark and roots are dried and powdered to make tonics, which are used to treat a variety of ailments such as fever, gastrointestinal problems, and malaria. The plant contains alkaloids, including strychnine and brucine, which are toxic and can cause convulsions and death if ingested in large quantities. As a result, it is important to use caution when using this plant for medicinal purposes.
The wood of the Strychnos vanderystii De Wild. plant is extremely hard and dense, making it a popular choice for making furniture, tool handles, and other wooden objects. It is also used for fuel and charcoal production. The bark of the tree is commonly used for making rope, while the leaves are used as a vegetable or as fodder for livestock.
Light requirements:
Strychnos vanderystii De Wild. requires full sun exposure for its optimal growth. The plant needs direct sunlight for at least 6 hours per day. Insufficient sunlight may lead to stunted growth and improper development of plant organs.
Temperature requirements:
The growth and development of Strychnos vanderystii De Wild. are largely affected by temperature. The plant requires warm temperatures - between 20 to 30°C - for optimal growth. Temperatures above 35°C should be avoided, as it can damage plant tissues. On the other hand, temperatures below 10°C can lead to frost damage.
Soil requirements:
The plant can withstand varied soil conditions, ranging from loamy to clay soils, as long as the soil is well-drained. It also grows better in slightly acidic to neutral soil with a pH range of 5.5 to 7.5. Strychnos vanderystii De Wild. needs sufficient nutrients, so applying organic matter such as compost can improve soil fertility. However, the plant is sensitive to soil salinity, so it should be planted in soil with low salt content.
Cultivation Methods
Strychnos vanderystii De Wild. is a tropical tree that requires warm, humid conditions and abundant sunlight. It thrives in well-draining soil and should be planted in a location that receives at least six hours of direct sunlight per day. When planting, the hole should be three times the width of the root ball to ensure the roots have room to grow. The plant can also be propagated from cuttings or seeds, with seeds being the easiest method.
Watering Needs
Strychnos vanderystii De Wild. requires regular watering to thrive. When newly planted, the tree should be watered twice a week until it is established. Once established, the tree should be watered deeply once a week during the dry season and every other week during the rainy season. The soil should be kept moist but not waterlogged to prevent root rot.
Fertilization
Strychnos vanderystii De Wild. benefits from regular fertilization to promote growth and health. A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium can be applied every three months during the growing season. A slow-release fertilizer can also be used to provide nutrients over an extended period. Be careful not to over-fertilize, as this can lead to nutrient burn and damage the plant.
Pruning
Strychnos vanderystii De Wild. requires little pruning to maintain its shape and health. Pruning should be done during the dry season, and any dead or diseased branches should be removed. The tree can also be pruned to promote branching and a fuller canopy. Cutting back the terminal bud can also encourage the tree to bush out and produce more flowers and fruit.
Propagation of Strychnos vanderystii De Wild.
Strychnos vanderystii De Wild., commonly known as Vanderyst's poison rope, is a tropical plant that belongs to the family Loganiaceae. This species is commonly found in the Congo Basin and is known for its medicinal properties. Propagation of this plant can be done through several methods.
Seed Propagation
Strychnos vanderystii De Wild. is propagated through seeds, which should be collected when the fruits turn yellow and have a hard outer shell. The seeds should be soaked in water for 24 hours before planting. The soil should be moist and well-draining, and the seedlings should be kept in partial shade until they are well established. Seedlings can be transplanted into larger pots or directly into the ground once they have grown to a suitable size.
Cuttings Propagation
Propagation of Strychnos vanderystii De Wild. can also be done through cuttings. Cuttings can be taken from the plant's stem, which should be at least 10-15cm long and planted in a well-draining soil mix. The cutting should be watered sparingly until it establishes roots, and it should be kept in partial shade until it develops new leaves. It is important to note that cuttings may take longer to establish compared to seed-grown plants.
Division Propagation
Division propagation is another method of propagating Strychnos vanderystii De Wild. This method involves dividing the plant's roots into sections and planting them in separate containers or directly in the ground. Care should be taken to ensure that each section has a sufficient number of roots and that the soil is moist and well-draining. The divided sections should be kept in partial shade until they establish new foliage.
Propagation of Strychnos vanderystii De Wild. is relatively easy, and the plant can be grown in a range of soil conditions. However, care should be taken with this plant, as it is highly toxic and can cause serious harm if ingested.
Disease Management
Strychnos vanderystii De Wild. is a plant that can be affected by various diseases. Here are some of the most common diseases that might affect the plant and possible management strategies:
- Leaf spot - This is a fungal disease that causes circular spots on the leaves. To manage this disease, remove all the infected leaves and ensure good air circulation around the plant.
- Powdery mildew - This is another fungal disease that can infect the plant. It causes a white powdery substance on the leaves and stems. To manage this disease, make sure the plant has good air circulation and avoid overhead watering.
- Root rot - Root rot is a disease caused by various fungi that infect the roots of the plant. It is often caused by overwatering or poor drainage. To manage this disease, ensure the plant is not overwatered and has good drainage.
Pest Management
Strychnos vanderystii De Wild. can also be affected by various pests. Here are some of the most common pests that might affect the plant and possible management strategies:
- Aphids - Aphids are small insects that suck the sap from the leaves and stems. To manage this pest, wash the plant with a strong stream of water or use an insecticidal soap.
- Mealybugs - Mealybugs are small insects that leave a white, cottony residue on the plant. To manage this pest, remove the infected plant parts and use an insecticidal soap.
- Spider mites - Spider mites are tiny spider-like pests that can harm the plant by sucking the sap from the leaves. To manage this pest, wash the plant with a strong stream of water or use an insecticidal soap.
With proper disease and pest management techniques, Strychnos vanderystii De Wild. can stay healthy and thrive in its environment.
