Strychnos suberosa De Wild. is a plant species that belongs to the family Loganiaceae. It is native to Southern Africa and is commonly found in Zimbabwe, Mozambique, Botswana, and Namibia.
Common names
The plant goes by several common names, including corky-seeded Poison Rope, spiny-seeded monkey orange, and suberoused nux-vomica.
Uses
The plant has been long used in traditional medicine due to its medicinal properties. The stem bark, root, and seeds of Strychnos suberosa De Wild. contain strychnine, an alkaloid that is known for its tonic, febrifuge, and antidote properties. It has been used to treat a variety of health issues such as fever, constipation, respiratory problems, and snake bites.

General appearance
Strychnos suberosa De Wild. is a large shrub or small evergreen tree that grows up to 4-5 meters tall. The plant has a straight trunk with grayish bark, the stem is extended and has small thorns or hooks, and the leaves are dark green and glossy on the upper surface. The flowers are small and white, and the fruit is a bright orange color with a hard and woody shell that contains seeds, which have characteristic corky ridges on its surface.
Light Requirements
The plant Strychnos suberosa De Wild. requires plenty of sunlight. It thrives in bright, direct sunlight and should be kept in a location with at least six hours of direct sunlight per day. Insufficient sunlight can stunt growth and cause the plant to become weak and vulnerable to diseases.
Temperature Requirements
Strychnos suberosa De Wild. is a tropical plant that prefers warm temperatures. Ideally, it should be kept in an environment with temperatures between 21°C and 32°C (70°F to 90°F). Avoid exposing the plant to cold drafts or temperatures below 15°C (59°F), which can cause damage and even death to the plant.
Soil Requirements
Strychnos suberosa De Wild. requires well-draining soil. The ideal soil should be rich in organic matter and have a pH that ranges between 6.0 to 6.5. The plant can tolerate a wide range of soil types, including sandy or loamy soils. However, it is important to avoid waterlogged soil and overwatering, as this can cause root rot and other fungal diseases.
Cultivation methods
Strychnos suberosa De Wild, commonly called corky-seeded poison rope or bush snake wood, is a slow-growing, evergreen plant that belongs to the Strychnaceae family. It is endemic to Africa and grows in semi-arid regions. To cultivate the plant, you need to start with healthy seeds or seedlings. Once you have acquired the desired planting material, choose a location with well-draining soil and partial sunlight. Strychnos suberosa De Wild. does not require intensive management, but it is best to keep it weed-free, especially in the early stages of growth.
Watering needs
Careful monitoring of the water requirements of Strychnos suberosa De Wild. is necessary due to its preference for semi-arid conditions. As a general rule of thumb, you should water the plant only when the soil feels dry. In the drier seasons, you may need to water the plant more frequently. Overwatering the plant is not advised as it can lead to root rot or wilting.
Fertilization
Strychnos suberosa De Wild. is a moderate feeder, and application of a slow-release, balanced fertilizer during planting is recommended. You may also apply a light application of fertilizer during the growing season to provide the plant with essential nutrients. If possible, choose organic fertilizers such as compost or manure over chemical fertilizers.
Pruning
Strychnos suberosa De Wild. requires little pruning as it has a naturally attractive growth habit. However, light pruning may be necessary to remove dead, damaged or crossing branches and to maintain the size and shape of the plant. Pruning should be done in the late winter or early spring before the start of active growth. After pruning, clean the pruning tools with rubbing alcohol to prevent the spread of diseases.
Propagation of Strychnos suberosa De Wild.
Strychnos suberosa De Wild., commonly known as the corky-fruited poison bean, is a tropical plant species that belongs to the Strychnaceae family. This plant can be propagated by seed, cutting, or grafting.
Seed Propagation
The easiest and most common method of propagating Strychnos suberosa is through seeds. The seeds are usually collected from the ripe fruit of the plant. After collecting the seeds, they should be soaked in warm water for about 24 hours to soften the outer seed coat. Then, the seeds can be planted in a well-draining potting mix and kept moist in a warm, sunny location. Germination usually takes between 2-4 weeks, and the seedlings can be transplanted to a larger container or to the garden bed once they are large enough.
Cutting Propagation
Strychnos suberosa can also be propagated by stem cuttings. The stem cuttings should be taken from the parent plant during the growing season. The cuttings should be about 15-20 cm long and have at least 2-3 nodes. The leaves on the lower half of the stem should be removed, and the stem should be dipped in rooting hormone powder. The cuttings can be placed in a potting mix or in water to root. Rooting usually takes between 4-6 weeks, and the new plants can be transplanted to a larger container or to the garden bed.
Grafting Propagation
Grafting is another method of propagating Strychnos suberosa. This method involves attaching a piece of the desired plant (scion) onto the rootstock of a closely related or compatible plant. Grafting is usually done during the dormant season, and the scion should be taken from a healthy, disease-free plant. The rootstock should be of a strong, vigorous variety that is resistant to pests and diseases. Once the graft has successfully taken, the new plant can be transplanted to the garden bed.
In conclusion, Strychnos suberosa De Wild. can be propagated by seed, cutting, or grafting. Each method has its advantages and disadvantages, and the choice of propagation method depends on factors such as the availability of plant materials, time, and resources.
Disease and Pest Management for Strychnos Suberosa De Wild.
As with any plant species, Strychnos suberosa De Wild. is susceptible to various diseases and pests. Effective management involves proper identification of these issues and implementing control measures that are specific to the problem at hand. Here are some common diseases and pests that may affect Strychnos suberosa De Wild., along with suggested management strategies:
Diseases
Anthracnose: This fungal disease causes leaf spot, stem canker, and fruit rot. To manage anthracnose, remove and destroy infected plant parts and avoid overhead watering. Fungicide applications may also be necessary.
Powdery mildew: This fungal disease appears as a white, powdery coating on the foliage. To manage powdery mildew, maintain good air circulation around the plant and avoid overhead watering. Fungicidal sprays may also be necessary.
Root rot: This disease is caused by various soil-borne fungi and can lead to wilting, yellowing leaves, and plant death. To manage root rot, ensure proper drainage, avoid overwatering, and remove infected plants and soil. Fungicidal drenches may also be necessary.
Pests
Aphids: These tiny, soft-bodied insects can cause distorted growth and transmit plant viruses. To manage aphids, spray plants with a strong stream of water or use insecticidal soap or oil.
Spider mites: These tiny pests suck plant sap and cause yellowing foliage. To manage spider mites, maintain good humidity levels and spray plants with water to dislodge them. Insecticidal sprays may also be necessary.
Scale insects: These pests have a hard, protective cover and suck plant sap. They can cause yellowing leaves and stunted growth. To manage scale insects, prune and destroy heavily infested plant parts and spray plants with horticultural oil.
By implementing appropriate management strategies, it is possible to keep Strychnos suberosa De Wild. healthy and productive.
