Osmanthus fragrans fruit can be harvested when it ripens in April-May and the peel changes from green to purple-black. Osmanthus fragrans seeds have post-ripening effect and have been stored in sand for at least half a year. After harvest, water the pile and go to the pulp. Seeds should be naturally dried in the shade and stored in sand. After sand storage, they can sow in autumn or spring.
During sand storage, it should be checked frequently to prevent the seeds from mildew or rodent damage. Generally, drilling is used for sowing and propagation. Before sowing, soil preparation should be done well and sufficient base fertilizer should be applied. It can also be planted in indoor seedbeds. When sowing, put the umbilical cord horizontally to avoid the radicle and young stem from bending, which will affect the growth of seedlings in the future.
After sowing, cover with a thin layer, then cover with grass, shade and moisturize, and always keep the soil moist, so that seedlings can emerge in the same year. The amount of seeds used per mu is about 20 kg, and about 30,000 seedlings can be produced. The seedlings can be transplanted and cultivated in the third year after growing in the seedbed for 2 years. The seedlings bloom late, and can bloom after 8- 10 years of colonization.
