1. Environment and lighting: Jasmine likes hot, humid and ventilated environment and needs sufficient lighting. Molly is afraid of cold. Potted jasmine in the south can be cultivated outdoors for the winter. In the north, keep warm in autumn and winter, move indoors and put it in the south direction. Strong sunlight makes branches strong, leaves dark green and flowers more fragrant, while insufficient sunlight makes flowers less fragrant. Second, moisture: jasmine is not drought-tolerant, but it is necessary to avoid water accumulation. Pour out the water in the basin in time during the rainy season, otherwise the leaves will turn yellow easily. Water the leaves twice a day on a hot sunny day in summer, once in the morning and once in the evening. If you find the leaves drooping, spray water on them to promote growth. 3. Soil: It is best to plant jasmine in fertile sandy and semi-sandy soil. When planted in slightly acidic soil with pH value of 6-6.5, the root system will be dense and grow vigorously. If the soil is sticky, lacks matrix, has low fertility and poor ventilation, there will be fewer roots, short plants, slender stems and leaves, and few and small flowers. Fertilization: The high temperature season in midsummer is the peak of jasmine growth. Apply more organic fertilizer and phosphorus and potassium fertilizer, such as peanut cake powder, bone meal, calcium superphosphate and multi-element flower fertilizer twice a month. In summer, jasmine is often leafy but does not bloom. The main reason is that too much nitrogen fertilizer is applied, resulting in too many branches and leaves. In this case, it is necessary to control fertilizer and water, apply more phosphorus and potassium fertilizers to promote germination, and at the same time pay attention to moving jasmine to a sunny and well-ventilated place. 5. Pruning: Jasmine grows very fast in summer, so it should be pruned in time. The base of potted jasmine is trimmed to 10 cm to 15 cm, which will promote most robust new shoots. For example, new shoots grow vigorously, and when they grow to 10 cm, they should be pruned to promote the growth of secondary branches, which will lead to more flowers and compact plant types. After the flowers wither, the branches should be cut off in time to reduce nutrient consumption, which is also conducive to promoting the growth of new shoots, making the branches dense, with more buds and more flowers. 6. Pest control: Jasmine often suffers from moth larvae, scale insects and red spiders, which are the most serious from July to September and often eat flower buds. It can be sprayed with universal powder or pyrethroid and 200 times of water once every half month, even if there are no pests and diseases, so as to prevent problems before they happen. The suitable spraying time is 9: 00 am and 4: 00 pm on sunny days, and it is not suitable to spray in the hot sun at noon to prevent phytotoxicity. Seven, flowering maintenance: don't spray water on the flowers during flowering to prevent premature flowering and fragrance loss. When it rains, the potted jasmine should be moved to a shelter.
