Culture methods of jasmine flowers

Jasmine flowers like to be warm and humid and grow best in a well-ventilated and semi-overcast environment. The soil is the most suitable for slightly acidic sandy soil which contains a lot of humus. Most varieties are afraid of cold and drought, and are not resistant to frost, waterlogging and alkaline soil. When the winter temperature is lower than 3 ℃, the branches and leaves are easy to suffer frost damage, and if they last for a long time, they will die.

Culture environment of jasmine

1. Lighting: Jasmine is fond of inflammation, heat, humidity, ventilation and breathable environment, which requires sufficient light. Jasmine is afraid of the cold. Potted jasmine in the south can be cultivated outdoors to survive the winter. In the north, it is necessary to keep warm in autumn and winter, and move indoors and put it toward the south. If the light is strong, the branches are strong, the leaves are dark green, the flowers are many and fragrant, and if the sun is not enough, the flowers are sparse and not fragrant.

2, moisture: Jasmine is not resistant to drought, but avoid stagnant water, rainy season should be timely dumping stagnant water in the basin, otherwise the leaves are easy to yellowing. In summer, hot and sunny days should be watered twice a day, once in the morning and evening, if you find that the leaves curl and droop should spray water on the leaves to promote growth.

3. Soil: it is better to cultivate jasmine in fertile sandy and semi-sandy soil. When planted in slightly acidic soil with pH value from 6 to 6.5, the root system is dense, the growth is vigorous, such as clay weight, lack of matrix, low fertility, poor ventilation, less root system, short plants, slender stems and leaves, and few flowers.

The propagation mode of jasmine

Jasmine multipurpose cuttings can also be pressed or ramets.

1. Cuttage propagation: from April to October, mature one-year-old branches were selected, cut into cuttings with more than two nodes, removed the lower leaves, inserted in the bed with half of the sediment, covered with plastic film, maintained high air humidity, and rooting in about 40 to 60 days.

2. Striping propagation: select longer branches, gently cut at the lower part of the node, bury them in a small basin containing sand and mud, often moisturize, and begin to take root in 20-30 days. After 2 months, they can be cut off from the mother plant and planted separately.

Planting methods of jasmine flowers

In midsummer, it is necessary to water early and late every day, such as dry air, need supplementary spraying; during winter dormancy, it is necessary to control the amount of watering, such as basin soil is too wet, it will cause rotten roots or fallen leaves. During the growth period, thin cake fertilizer should be applied once a week. After changing pots in spring, you should often pick the heart for plastic surgery, and re-cut it after flowering to facilitate the germination of new branches, so that the plant is neat and robust and blossoms vigorously.

Fertilization method of Jasmine Flower

From June to September, liquid fertilizer containing more phosphorus is frequently applied, preferably every 2-3 days. Fertilizer can be made of mature bean cake and fishy water fertilizer liquid, or ammonium sulfate and calcium superphosphate. In general, more chemical fertilizer ingredients will burn jasmine plants. 0.1% potassium dihydrogen phosphate aqueous solution can also be used to spray the foliar surface in the evening, or it can promote more flowering.

Flowering maintenance of Jasmine Flower

Jasmine likes fertilizer very much, and potted jasmine can blossom three times a year as long as it is properly maintained. If there is not enough fertilizer and nutrients, after blooming once, it will no longer blossom. If the management is in place, it can be opened continuously from the end of May to the beginning of November. The key is the mastery of pruning, sunshine, and water.

Jasmine has blossomed one after another since early summer. If properly managed, there can be three periods of blooming.

In early June, jasmine blossoms one after another, and the method of picking flowers is to pick the twigs with leaves to promote the re-emergence of new branches and luxuriant branches and leaves. At this time, apply light fertilizer and water twice a week, and keep the basin soil moist.

The first flowering period is from late June to early July, when it is necessary to strengthen the management of fertilizer and water, apply thin fertilizer frequently, fertilize once every 2 days, and apply fully mature organic liquid fertilizer, the ratio of fertilizer to water is 1:4. Watering should be adequate, usually once a day. Usually watering should be carried out in the morning, while fertilization should be carried out in the evening. This lasts until late July, because there is plenty of fertilizer and water, which can make the flowers bloom bigger and more.

In the first ten days of August, the second stage of flower formation, at this time fertilization should be slightly thicker than before, generally with half fertilizer and half water. In order to make jasmine blossom better, calcium superphosphate solution can also be sprayed on the leaf surface. In late August, fertilization was gradually reduced and applied once every 6-7 days, but watering was still needed and kept once every 2 days.

From early September to early October, the third stage of flower formation, at this time should stop fertilization, watering should also gradually reduce, because the weather has gradually turned cool, will affect the formation of bud, so the number of these flowers is less, to the end of flowering after the middle of October, just keep the pot soil slightly wet.

Pest control

1. Pest control

The main pests of jasmine are leaf roll moth and red spider, which damage the top tip and tender leaves, so we should pay attention to timely control. For red spiders (mites), try not to use dichlorvos and dimethoate, because the smell of these two pesticides is too strong (many days can not be dispersed, especially fumigating), and are not specific drugs for red spiders.
