Hello, I hope the following answers can help you, and I hope to adopt them! Key points of jasmine conservation: 1. Temperature: Jasmine likes high temperature. Generally, it begins to germinate at around 20℃, germinates above 25℃ and germinates at around 28℃ to 33℃. The suitable temperature for its growth is 22 ~ 35℃. If the temperature is too high, the plant is in a semi-dormant state, and the flowers are few and uneven. If the temperature is too low, plants grow slowly and can't stand the low temperature. 2, lighting: Jasmine likes sunny environment, full of light, dark green leaves, thick branches, many buds, good coloring and rich aroma. Otherwise, the plant will grow white, with light green and thin leaves, slender branches, long and tender internodes, few buds, small flowers and light fragrance. 3. Moisture: Jasmine likes moist soil. However, for fear of water accumulation in the basin, if the basin soil is kept wet for a long time, the roots will rot due to lack of oxygen in the basin soil, the leaves will gradually turn yellow and fall off, and even the whole plant will die. 4. Fertilization: Jasmine likes to fertilize, but it should be fertilized according to its growth law. When the temperature exceeds 35℃ in winter and summer, we should keep enough reasonable fertilizer, pay attention to the uniform ratio of nitrogen, phosphorus and potassium fertilizer, and give priority to phosphorus and potassium fertilizer in bud stage to promote the formation of more flower buds. It is forbidden to apply excessive chemical fertilizer or immature organic fertilizer to avoid burning roots and yellowing leaves, and every 65,438+during the whole growth period. 5. Pest control: Jasmine is vulnerable to pests such as red spider, so it is necessary to strengthen ventilation, pay attention to observation at ordinary times, and use dicofol to control it in time once the insect body is found to be harmful. Jasmine leaf spot is a common disease of jasmine, which usually occurs in May-June and peaks in July-August. At the beginning of the disease, light brown spots appeared on the infected leaves, and then spread around. The lesion site is thin, brown, transparent, round or irregular, thin, translucent and brown, and the edge of the lesion is obvious. Finally, black particles were born on the lesion. The diseased leaves should be removed in time and destroyed centrally. Spraying 600-800 times solution of 65% zineb wettable powder or 800 times solution of 75% chlorothalonil wettable powder for 3-4 times at intervals of 10 to 14 days. How can jasmine blossom bigger? 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. 2, moisture: jasmine is not drought-tolerant, but also avoid water. In the rainy season, the accumulated water in the basin should be poured out in time, 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. 4. 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, multi-element flower fertilizer, etc., 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. Pruning the base of potted jasmine to 10 cm to 15 cm will promote the growth of most stout 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. 7. Maintenance of flowering period: Do not spray water on flowers during flowering period to avoid premature flowering and loss of fragrance. When it rains, move the potted jasmine to a shelter. I hope the above answer can help you, I still adopt it!
