Cymes, terminal or axillary, with 3-9 flowers and a white corolla, are extremely fragrant. Flowering: June -65438+ 10. Sexual preference is warm and humid, and it grows best in a well-ventilated semi-cloudy environment. The most suitable soil is slightly acidic sandy loam containing a lot of humus. Afraid of cold, drought, waterlogging and alkaline earth. When the temperature is lower than 3℃ in winter, branches and leaves are vulnerable to freezing injury, and will die if it lasts for a long time.

Select mature 1 year-old branches, cut them into more than 2 cuttings, remove the lower leaves, insert them in a semi-muddy bed, cover them with plastic film, keep the air humidity high, and take root after about 40-60 days. Propagation by layering, selecting long branches, cutting them slightly at the lower part of the nodes, burying them in a small basin filled with sand and mud, keeping moisture frequently, and taking root after 20-30 days. After two months, they can be cut from the mother plant to become seedlings and planted separately. Potted jasmine should be watered every morning and evening in summer. If the air is dry, add water. During the winter dormancy period, it is necessary to control the amount of watering. If the pot soil is too wet, it will cause rotten roots or fallen leaves. Apply pancake fertilizer once a week during the growing period. After changing pots in spring, we should always pick our hearts and shape them. Cut it again after flowering to help sprout new branches, so that plants can be neat and robust and bloom vigorously.

The main pests are leaf roller moth and red spider, which harm the top young leaves and should be prevented in time. Jasmine leaves are green, white and fragrant.
