The propagation mode of winter jasmine is mainly cutting, and it can also be propagated by layering and branching. If landscaping needs large-scale mass reproduction, of course, cutting seedlings is the fastest way. Spring, summer and autumn are fine. Cut the semi-lignified branches with the length of 12- 15cm and insert them directly into the sand. At the beginning, it needs watering and moisturizing, and it takes about 15 days to take root. When new shoots and leaves are lignified, they can be transplanted into flowerpots.

Conservation of winter jasmine:

Watering: The emphasis is on summer and winter. In summer, because of the heat, we must water more. When the soil surface is dry, we should water it. Adequate water is also a necessary condition for the growth of the Spring Festival. In winter, the temperature is low and the water in the basin dries slowly. The lower the temperature, the lower the watering frequency, which has a great impact on the environment and cannot be directly watered. Better water it half.

Lighting: In the hot summer sunshine and high temperature, the winter jasmine should be moved to a semi-shady place, which is more conducive to its growth. Before and after the Spring Festival, the winter jasmine will be moved indoors for conservation. Ensure that the room temperature is around 15℃, and flowers can be seen after 15 days.

Fertilization: when potted, put a few hooves in the pot as base fertilizer. Or add a small amount of organic fertilizer when preparing flower soil. In the growing season of winter jasmine, apply 1~2 decomposed dilute liquid fertilizer every month. July-August is the flower bud differentiation period of Jasminum nudiflorum, so more phosphate fertilizer should be applied to promote flower bud differentiation. At the beginning of flowering, applying decomposed organic liquid fertilizer once can ensure the bright color of winter jasmine and prolong the flowering period.

Temperature: There is no need to control the temperature for the maintenance of winter jasmine, because it can grow even if the temperature is too cold, with a low temperature of about 4 degrees. However, in the case of prolonged or early flowering, it is very effective to increase the temperature, in which the temperature is about 18 degrees, which can effectively promote the early flowering of winter jasmine, and the temperature as low as 6 degrees can prolong the flowering of winter jasmine.

Pruning: During the growing season, the extra branches of Jasminum nudiflorum should be cored in time to control vigorous growth. Prune strong branches, disorderly branches and insect branches in mid-May. In June, the new shoots can leave 2-3 short segments at the base to concentrate nutrition and promote flower bud differentiation. Of course, some branches can stay for a long time because of the need of bonsai modeling.

Pest control: Winter jasmine often suffers from leaf spot and dead branch disease, and can be sprayed with 1500 times of 50% wettable powder. Insect pests do great harm to aphids and giant salamander, spraying 50% phoxim EC 1000 times.
