The seeds are known for their psychotropic effects, inducing lucid dreaming and enhancing the dream state. The seeds are also used in some cultures for divination, which involves interpreting messages revealed in a dream. The seeds are also used in jewelry-making and as good-luck charms.
Finally, the large, shiny, and impressive seed pods of Entada rotundifolia Harms are often used for decoration purposes and as ornamental items, due to their unique shape, size, and smooth surface.
Light Requirements
Entada rotundifolia Harms requires full sun to partial shade for optimal growth. It can tolerate some shade but may not produce as many flowers or fruits in low light conditions.
Temperature Requirements
The ideal temperature range for Entada rotundifolia Harms is between 20°C to 30°C. It can tolerate temperatures as low as 15°C and as high as 35°C but may not grow as vigorously or produce as many fruits in extreme temperature conditions.
Soil Requirements
Entada rotundifolia Harms prefers well-draining soils that are rich in organic matter. It can grow in a variety of soil types, including sandy, loamy, and clay soils. However, it cannot tolerate waterlogged soils as it can lead to root rot and other fungal diseases.
The plant also prefers soils with a pH range of 6.0 to 7.5, that is slightly acidic to slightly alkaline. Soil fertility is crucial for optimal growth and fruit production. The addition of compost or other organic fertilizers can significantly enhance the soil's nutrient content.
Cultivation Methods
Entada rotundifolia Harms is typically grown in a tropical climate with a temperature range of 20 to 30 degrees Celsius. It prefers well-draining soil with a pH range of 6.0 to 7.5. This plant is typically propagated from seeds, and seedlings must be watered in moderation until they are established. Proper drainage should also be provided to avoid overwatering, which can cause root rot.
Watering Needs
Entada rotundifolia Harms requires regular watering while it is establishing its root system. Once the plant is established, it can tolerate periods of drought. However, it is important to avoid overwatering as this can cause root rot. The plant requires moist soil, so it is essential to ensure proper drainage to avoid waterlogged soil.
Fertilization
Entada rotundifolia Harms benefits from regular fertilization to promote growth. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium should be applied during the growing season, every two weeks. It can also benefit from the application of organic fertilizers, such as compost or manure. It is essential to avoid over-fertilization as this can cause damage to the plant.
Pruning
Entada rotundifolia Harms does not require regular pruning, but occasional pruning of dead or diseased branches is necessary. This will help to prevent the spread of disease and promote healthy growth. Pruning is best done during the dormant season, and it is essential to use clean and sharp tools to avoid causing damage to the plant.
Propagation methods for Entada rotundifolia Harms
Entada rotundifolia Harms, commonly known as the African dream herb, is a tropical climber that belongs to the Fabaceae family. The plant propagates through seeds, root cuttings, and stem cuttings, but the most reliable method is through seeds.
Seed propagation
The seeds of Entada rotundifolia Harms are available in most tropical plant nurseries. The seeds should be soaked overnight before sowing to facilitate germination. A mixture of sand, soil, and compost should be used to sow the seeds, which can be spaced 60 cm apart in the soil. The seeds should be covered with a thin layer of soil and kept moist.
The seedlings usually emerge within 10-14 days. Once the seedlings have grown to about 15 cm in height, they can be transplanted to the main field, where they can be spaced 2-3 m apart. It is essential to provide support for the plant to climb, as weak stems could break under the weight of large leaves and seed pods.
Root and stem cutting propagation
Propagation through root and stem cuttings is also possible, although it is not as reliable as seed propagation. Root cuttings should be taken from healthy plants in the spring or fall, and they should be 10-15 cm long. The cuttings should be dipped in a rooting hormone and planted in a mixture of sand and soil. They should be kept in a humid environment and watered regularly.
Stem cuttings should be taken from mature plants during the summer season. The cuttings should be about 20 cm long and should contain at least two nodes. The cuttings should be dipped in a rooting hormone and planted in a mixture of sand and soil. The cuttings should be kept in a humid environment and watered regularly. Rooting usually takes 2-3 weeks.
In conclusion, Entada rotundifolia Harms, commonly known as the African dream herb, can be propagated through seeds, root cuttings, and stem cuttings. Seed propagation is the most reliable method, while root and stem cuttings are less reliable. Proper care should be given to ensure successful propagation.
