I. Soil quality
Potted jasmine requires that the cultivated soil is rich in organic matter and has good water permeability and air permeability. 4 parts of general garden soil, 4 parts of compost, 2 parts of river sand or chaff ash, and a proper amount of fully decomposed dry cake powder, chicken and duck manure, etc. Sieve off powder and coarse particles, and cover the surface with coarse particles.
Second, moisture.
After planting, water the roots, then put them in a slightly shady place for 7- 10 days to avoid direct sunlight, and then gradually see the light.
The key to daily management is water. According to the characteristics of jasmine, such as being wet-loving, not drought-tolerant, afraid of stagnant water and breathable, we should master the time and amount of watering.
It can bloom in June-July. At this time, the root system has resumed normal growth, and thin alum fertilizer water should be poured every 7- 10 days.
In the future, it can be managed according to adult jasmine, and the pots will not be changed in that year.
Third, pruning
In order to make the potted jasmine plants plump and beautiful, the damaged branches should be cut off immediately after the flowers wither, so as to promote the germination of new techniques at the base and control the height of the plants.
Fertilization was stopped in early September to improve the maturity of branches and facilitate overwintering.
Molly is afraid of cold. When the temperature drops to 6-7℃, it should be moved indoors, and at the same time, pay attention to opening the window for ventilation, so as not to cause the leaves to turn yellow and fall off. The temperature is often unstable at this time. In the case of warm weather, it is still necessary to move outdoors for ventilation.
When jasmine is moved indoors for the winter, it should be placed in a sunny room with room temperature above 5℃.
Water 1 time every 7 days or so to make the basin soil slightly wet. In this way, the branches and leaves can remain bright green in winter without losing the ornamental effect.
Fourth, fertilization.
Jasmine likes fertilizer, but it should be fertilized according to its growth law. When the temperature exceeds 35℃ in winter and summer, we should keep enough reasonable fertilizers, pay attention to the uniform proportion of nitrogen, phosphorus and potassium fertilizer, and give priority to phosphorus and potassium fertilizer in bud stage.
In order to promote the formation of more flower buds, it is forbidden to use excessive fertilization or immature organic fertilizer to avoid burning roots and yellowing leaves. During the whole growth period, the prepared alum fertilizer water or ferrous sulfate solution is sprayed once every 1 ~ 2 weeks.
5, pest control
Jasmine is vulnerable to pests such as red spider, so it is necessary to strengthen ventilation and observe at ordinary times. Once pests are found, dicofol should be used for prevention and control in time. 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. During the onset period, 600 ~ 800 times of 65% zineb wettable powder or 800 times of 75% chlorothalonil wettable powder were sprayed every 10 ~/4 days for 3 ~ 4 times.
