Growth Characteristics- Environment: It grows well in moist, fertile soil, and growth is further promoted in sunny locations. It possesses the ability to fix nitrogen through a symbiotic relationship with its own root nodules.
- Size: Mature trees can grow to an average height of over 10 meters.
- Leaves and Flowers: The leaves grow in an ovate or elliptical shape and turn yellow in the autumn. Flowers bloom in the spring as monoecious plants, with small yellowish-green blossoms appearing in clusters.

Propagation Methods- Seeds: Seeds are extracted from fruits harvested in the autumn and sown directly in late autumn or the following spring.
- Grafting: While propagation is possible via grafting, propagation by seeds is generally more commonly used.

Cultivation Methods- Soil: It grows well in well-drained soil rich in organic matter. - Watering: Sufficient watering is required in the early stages, but once the tree matures, it can rely on natural rainfall.
- Fertilizer: Providing an appropriate amount of potassium phosphate fertilizer during the growing season is beneficial.

Important Pests and Control Methods
- Diseases: Leaf fungal diseases are the main issue; proper ventilation management and the removal of diseased leaves help with prevention.
