Seek Milan, jasmine breeding experience.

Like warm, humid and sunny environment, not cold-resistant, slightly shade-tolerant. Loose and fertile slightly acidic soil is the best, and the temperature in winter is not lower than 10℃.

Milan likes warmth, sunshine and fatness. The optimum growth temperature is 20℃ ~ 25℃. Under normal circumstances, when the sunshine is sufficient and the temperature is high (about 30℃), the flowers will have a strong fragrance. If you put it in the shade in summer and apply a lot of nitrogen fertilizer at the same time, it is one of the main reasons why Milan doesn't bloom or bloom less and its fragrance is weak. Therefore, during the growth and development of Milan, it is necessary to maintain it in a sunny place outdoors, and pay attention to the appropriate application of liquid fertilizer containing more phosphorus. It is best to use rotten alum water such as broken bones, fish bones, chicken bones, etc., and often add some fertilizers containing more phosphorus or fermented rice washing water, which is helpful for budding, flowering, golden color and fragrant smell.

Milan likes humidity, so water it properly during the growing period. Too much watering can easily lead to rotten roots and yellow leaves falling off; Too much watering during flowering period is easy to cause falling flowers and buds; Too little watering will cause leaves to dry up and buds to wither. Therefore, when the temperature is high in summer, in addition to watering 1 ~ 2 times a day, we should often spray branches and leaves with clear water and sprinkle water on the ground to improve the air humidity.

At the same time, fertilization should be appropriate. Because Milan has a large number of flowers a year, it is necessary to topdressing 2 ~ 3 times of fully decomposed dilute liquid fertilizer in time after each flower, so as to make bloom endless and full of fragrance. Milan likes acidic soil, and humus-based culture soil should be used for potted plants. In the vigorous growth period, spraying 0.2% ferrous sulfate solution once a week will make leaves turn green and flowers multiply.

jasmine

In early June, jasmine bloomed ahead of schedule. The method of picking flowers is to pick off the tender branches with leaves, so as to make the new branches sprout again and flourish. At this time, light fat water is applied twice a week to keep the basin soil moist.

Late June to early July is the first stage of flowering. At this time, it is necessary to strengthen the management of fertilizer and water, apply thin fertilizer frequently, apply/kloc-0 every two days, and apply fully decomposed organic liquid fertilizer, with the ratio of fertilizer to water of 1: 4. Watering should be sufficient, generally 2 days 1 time. Usually watering should be done in the morning and fertilizing should be done at night. This will last until the end of July, and the water bloom will be bigger because of the rich fertilizer and water.

In early August, the second stage of flowering, when fertilization is slightly thicker than before, it is generally appropriate to divide fertilizer and water equally. In order to promote jasmine to bloom better, calcium superphosphate solution can also be sprayed on the leaves. By the end of August, fertilization was gradually reduced, and 1 time was applied for 6 to 7 days, but more water was needed, and 1 time was maintained for 2 days.

From early September to early 10, the third stage flower is formed. At this time, fertilization should be stopped and the amount of watering should be gradually reduced. Because the weather has gradually turned cold, which will affect the formation of flower buds, the number of these flowers is small, and the flowering will end after the middle of 10, and the pot soil can be kept slightly wet.

Suitable fertilization methods

During the flowering period from June to September, liquid fertilizer containing more phosphorus should be applied frequently, preferably once every 2-3 days. The fertilizer can be decomposed bean cake and fishy liquid fertilizer, or ammonium sulfate and calcium superphosphate. Generally, too much chemical fertilizer will burn jasmine plants. You can also spray leaves with 0. 1% potassium dihydrogen phosphate aqueous solution at night, which can also promote them to bloom more.
