Jasmine is warm and moist, and grows best in a well-ventilated, semi-yin environment. The soil is most suitable for the slightly acidic sandy soil containing a large amount of humus. Most species are chills, dreads, and are not resistant to frost, wet sputum and alkaline earth. When the temperature in winter is lower than 3 °C, the foliage is susceptible to freezing damage, and if it lasts for a long time, it will die.
1. Illumination: Jasmine is hot, humid, ventilated and ventilated, requiring sufficient light. Jasmine chills, the southern potted jasmine can be cultivated outside the winter, the north in the autumn and winter need to do warm work, moved indoors in the south direction. When the light is strong, the branches are strong, the leaves are dark green, the flowers are fragrant, and when the sunlight is insufficient, the flowers are less and less fragrant.
2, moisture: jasmine is not drought-tolerant, but also avoid stagnant water, rainy season should dump the water in the basin in time, otherwise the leaves are prone to yellow. In summer, hot and sunny days should be watered twice a day, once in the morning and evening. If the leaf curls are found, water should be sprayed on the leaves to promote growth.
3, soil: cultivated jasmine soil to fertile sandy and semi-sand soil is good, planted in slightly acidic soil with pH of 6 to 6.5, the roots are dense, strong growth, such as soily weight, lack of matrix, fertility Low, poor ventilation, the root system is small, the plant is short, the stems and leaves are slender, and the flowers are small and small.
Jasmine breeding uses cuttings, and can also be pressed or ramets.
1. Cutting propagation: carried out from April to October, selecting mature 1 year old branches, cutting into cuttings with more than two nodes, removing the lower leaves, inserting the inserts in the mud and half, covering the plastic film, keeping it high Air humidity, rooting after about 40 to 60 days.
2, the production of beading: the use of longer branches, gently scratched in the lower part of the section, buried in the small pot of sand, often moisturizing, 20 to 30 days began to root, after 2 months can be separated from the mother plant , planted separately.
In the summer, water should be watered early and late every day. If the air is dry, it needs to be replenished. In the winter dormancy period, the amount of water should be controlled. If the soil is too wet, it will cause rotten roots or fallen leaves. It is necessary to apply a thin pancake once a week during the growth period. After changing the basin in the spring, it is necessary to pick the heart and shape it regularly. After the flowering period, it should be cut again to facilitate the sprouting of new branches, so that the plants are neat and strong, and the flowers are vigorous.
From June to September, the liquid fertilizer with more phosphorus is applied in the flowering period, preferably every 2 to 3 days. The fertilizer can be used to make the bean cake and the fish water, or the ammonium sulfate, the superphosphate, the general fertilizer. When the ingredients are mixed, the jasmine plants will be burned. It can also be sprayed on the foliage in the evening with 0.1% potassium dihydrogen phosphate aqueous solution, which can also promote more flowering.
Flowering maintenance of jasmine
Jasmine is very good for fat, as long as it is properly maintained, potted jasmine can be opened three times a year. If the fertilizer is insufficient and the nutrients are not enough, after the flower is opened, it will no longer bloom. If management is in place, it can be kept from the end of May to the beginning of November. The key is the mastery of trimming, sunshine, and fertilizer.
Jasmine blossoms from early summer, and if properly managed, there may be three flowers.
In early June, jasmine began to bloom early, and the method of picking flowers was to remove the leaves with the leaves, and promote the new shoots to re-emerge. At this time, apply twice a week of light fertilizer water and keep the soil moist.
From the end of June to the beginning of July, it is the first stage of full bloom. At this time, it is necessary to strengthen the management of fertilizer and water, apply thin fertilizer and apply fertilizer once every 2 days, and apply fully decomposed organic liquid fertilizer. The ratio of fertilizer to water is 1:4. Watering should be sufficient, usually once a day. Usually watering should be done in the morning, while fertilization is better in the evening. This continues until the end of July, because the fertilizer is sufficient, the flowers can be opened up.
In the first ten days of August, the second phase of flower formation, at this time fertilization is slightly thicker than before, generally suitable for fertilizer and water. In order to promote better flowering of jasmine, a superphosphate solution can also be sprayed onto the foliage. By the end of August, the fertilization will be gradually reduced, and once every 6 to 7 days, the watering will still need more, and it will be kept once every 2 days.
From the beginning of September to the beginning of October, the third flower is formed. At this time, the fertilization should be stopped, and the amount of watering should be gradually reduced. As the weather has gradually turned cold, the formation of the flower buds will be affected, so the number of flowers is small. After the end of October, the flowering is over, just keep the soil slightly wet.
