Propagation Methods - Seed Propagation: Collect mature fruits in the autumn, extract the seeds, and plant them. Since the germination rate is not high, it is recommended to plant a relatively large quantity. - Cuttings: You can propagate by cutting healthy branches in the spring or autumn. Cultivation Methods - Planting: Planting in the spring or autumn is recommended. Plant them at sufficient intervals to ensure space for later growth. - Watering: During the growing season, water thoroughly, ensuring good drainage.
