Light Requirements
Strychnos bicirrifera Dunkley requires plenty of bright, indirect light to grow well. These plants should be placed near a window where they can receive at least six hours of sunlight per day. Insufficient light can cause the plant to become leggy and weak, while too much direct light can burn the leaves.
Temperature Requirements
The ideal temperature range for Strychnos bicirrifera Dunkley is between 65°F and 75°F (18°C to 24°C). These plants do not tolerate extreme temperatures, such as frost or high temperatures above 80°F (27°C). If the temperature fluctuates too much, the plant may drop its leaves or become dormant.
Soil Requirements
Strychnos bicirrifera Dunkley requires soil that is well-draining and rich in organic matter. The pH of the soil should be slightly acidic, between 5.5 and 6.5. A soil mix that contains peat moss, perlite, and vermiculite can provide the necessary drainage and aeration requirements. The plant should be repotted every one to two years using fresh soil.
Cultivation
Strychnos bicirrifera Dunkley, commonly known as the othok or wooden-fruited strychnos, can be cultivated in a variety of soils, including sandy, loamy, and clay. However, it tends to do better in well-draining soils with a pH range of 5.5 to 6.5. This plant thrives in warm climates and prefers temperatures between 18°C and 30°C. It can tolerate direct sunlight but also grows well in partial shade. Strychnos bicirrifera Dunkley can be propagated by seed or stem cuttings.
Watering needs
During dry spells, strychnos bicirrifera Dunkley requires regular watering to keep it moist. The plant will need to be watered once or twice a week, depending on the prevailing weather conditions. It is crucial to water the plant at the base to prevent fungal diseases. The plant does not like standing water, and it is vital to ensure that the water drains well from the soil.
Fertilization
Strychnos bicirrifera Dunkley requires regular feeding during the growing season to ensure robust growth. Apply all-purpose fertilizer with an N-P-K ratio of 10-10-10 or a similar balance of nutrients. You should fertilize the plant every three months with a slow-release fertilizer or use organic fertilizers such as compost or manure. Avoid over-fertilizing the plant, which may cause it to become leggy and weak.
Pruning
Pruning should be done after harvesting the fruits and when the plant is dormant. It is advisable to remove all the dead, broken, or diseased branches. You should also prune suckers or weak stems to allow the plant to channel its energy to the healthy parts. The goal of pruning is to maintain the plant's natural shape, promote good airflow, and encourage the growth of new branches. Pruning the plant regularly will also stimulate the growth of new fruiting branches.
Propagation of Strychnos bicirrifera Dunkley
Strychnos bicirrifera Dunkley is commonly known as the African snake bean due to its twisted, elongated fruit pods that resemble snakes. The plant is native to tropical Africa and is commonly found in dry forests and woodlands. Propagation of Strychnos bicirrifera Dunkley is usually done through seeds and cuttings.
Propagation through Seeds
The propagation of Strychnos bicirrifera Dunkley through seeds is easily done by obtaining mature seeds from the plant's fruit pods. Ripe seeds are brown or black and have a firm coat. They should be sown immediately after harvest as they do not have a long shelf-life. Storage should also be done under cool, dry conditions to maintain their viability.
Seeds should be sown in well-prepared beds or pots filled with compost and sand in equal amounts. They should be sown at a depth of two to three times their size, and the soil should be kept moist throughout the germination period, which can take up to six weeks. After the seedlings have attained sufficient growth, they can be planted out in well-drained soil.
Propagation through Cuttings
Propagation of Strychnos bicirrifera Dunkley through cuttings is usually done during the rainy season when the soil is moist. Semi-hardwood cuttings, which are usually seven to ten centimeters long, are taken from the plant's branch tips and planted in a well-drained nursery bed.
The cuttings are then watered daily and kept under shade until roots develop in about four weeks. They are then transplanted into pots and allowed to grow until they are ready to be planted out into the field.
While propagation through cuttings is an effective method, it is usually not the preferred method due to the slow growth of the cuttings.
Disease and Pest Management for Strychnos bicirrifera Dunkley
Strychnos bicirrifera Dunkley is a plant that is known to be quite hardy, but like any other plant, it can be susceptible to pests and diseases. Proper management is key to ensuring that the plant remains healthy and productive.

One of the most common diseases that can affect Strychnos bicirrifera Dunkley is powdery mildew. This fungal infection usually appears as a white, powdery coating on the leaves of the plant. To manage this disease, it is recommended to dispose of all infected plant parts and to avoid overhead watering. Fungicide sprays can also be used to control the spread of powdery mildew.
Another common disease that the plant might suffer from is leaf spot. This is usually characterized by dark, circular spots on the leaves. To manage leaf spot, it is recommended to ensure proper air circulation around the plant and to avoid overhead watering. Infected plant parts should also be removed and disposed of properly.
Common Pests
One of the most common pests that can affect Strychnos bicirrifera Dunkley is spider mites. These tiny pests are known to weave webs on the plants and feed on the leaves. To manage spider mites, it is recommended to regularly spray the plant with water and to use insecticidal soap to control their population.
Another common pest that can affect the plant is mealybugs. These pests usually appear as tiny, white cotton-like masses on the leaves and stems of the plant. To manage mealybugs, it is recommended to prune and dispose of all infected plant parts. Insecticidal soap and neem oil can also be used to control their population.
Conclusion
Overall, proper management is key to ensuring that Strychnos bicirrifera Dunkley remains healthy and productive. Regular inspection and early detection of pests and diseases are crucial for effective management. It is also important to follow proper cultural practices like proper watering, fertilization, and pruning to keep the plant healthy and resilient.
