Pot culture methods and matters needing attention of jasmine

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.

Biological control: removal of dead branches and leaves and concentrated watering can reduce part of the overwintering base and protect and utilize natural enemies. Predatory mites, ladybugs, lacewings and thrips all have a certain control effect on mites, so the safety of natural enemies should be considered when choosing insecticides, and if conditions exist, natural enemies can be released artificially.

Chemical control: red spiders have strong reproductive ability, strong pressure on the selection of agents, and are easy to produce drug resistance, so drugs should be used in time and rotation. The commonly used agents and concentrations are 25% triazoltin wettable powder 1000 × 2000 times, 50% bromine mite EC 2000 times, 20% formamidine EC 1000 times, 20% triclofenac 1000 times, 50% dichlorofos EC 1000 times, 40% omethoate 1000 times. Note that the above agents should not be mixed with Bordeaux liquid and other alkaline pesticides.

2. White silk disease

Symptoms: mostly occurred at the base of the stem. The susceptible plants became brown and rotten, the skin of the diseased part was easy to peel off, and white sericeous hyphae were produced on the surface. In the later stage, rapeseed-like sclerotia appeared in the disease. The pathogen overwinters with sclerotia or mycelium in the soil or on the disease residue. Rain Water is prone to repeated infection when there are many times from May to June and August to September every year.

① removed the remains of diseased plants in time and destroyed them centrally.

② should strengthen management, strict quarantine and put an end to the source of disease.

At the beginning of ③ disease, the surrounding soil was disinfected with 70% pentachloronitrobenzene, or sprayed with 1% Bordeaux solution or 0.3 Baumedu stone sulfur mixture, or 50% wettable antiseptic soil for prevention and treatment. When the disease is serious, spray 75% chlorothalonil wettable powder 800-1000 times liquid, or 65% Dessen zinc wettable powder 800 times liquid.

④ uses 82 Trichoderma bran biological preparation, mixed with fine soil, mixed in the basin soil.

3. Anthrax

Symptoms: mainly harm leaves, sometimes also harm tender shoots. At the beginning of the disease, there are small light green to yellow spots on the leaf surface, and gradually expand into grayish brown or gray-white round or near-round spots. Black dots are scattered on the plaque in the later stage. The pathogen overwintered on the damaged leaves with conidia and mycelium. Generally, the disease is more serious in summer and autumn.

① should strengthen the cultivation management, remove and destroy the diseased leaves in time.

② disease is sprayed 2 times 3 times, 70%, 600 times, 800 times, and once every 10 days. 0.1% liter of mercury solution or purple potion can also be applied in the family.

When the disease of ③ is serious, spray 50% thiophanate or 75% chlorothalonil wettable powder 800-1000 times, or 50% carbendazim 1000 times, 65% Dysen zinc 500 times.

4. Leaf spot

Symptoms: most of them occur in the leaves. At the beginning of the disease, brown spots were produced on the leaves, which gradually expanded into round or irregular shapes, the disease became thinner, brown and transparent, and black particles appeared on the spots. Pathogens overwintered on diseased leaves by mycelium or conidia. It usually occurs from May to June, and the peak period is from July to August.

The diseased leaves were cut off and destroyed by ① in time.

② applied less nitrogen fertilizer and more phosphorus and potassium fertilizer.

③ disease is initially sprayed with 70% Rocco 600k800 times, once every 10 days, or 65% Dyson zinc 600,800 times, or 1% equivalent Bordeaux solution of 1 ∶ and 1 ∶.

5. Soot disease

Symptoms: dark brown mildew spots appeared on the leaves at the beginning of the disease, which gradually expanded to form a black soot-like mildew layer. The disease is caused by bacterial breeding caused by the excrement of aphids and shell insects.

① strengthens management and improves ventilation conditions.

② eliminates aphids and scale insects in time.

Spray 160x equivalent Bordeaux solution before the onset of ③; at the beginning of the disease, spray 50% carbendazim wettable powder 800-1000 times.

How to raise jasmine flower culture method and matters needing attention

Jasmine can be used not only for us to watch but also to make tea, which is very popular with everyone, so how to raise jasmine has become what everyone wants to know. Here are the methods and precautions for jasmine cultivation.

The culture method of jasmine:

1. Environment and light: Jasmine is hot, humid, ventilated and breathable, requiring 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. Fertilization: the high temperature season in midsummer is the peak period for jasmine growth, applying more organic fertilizer and phosphorus and potassium fertilizer, such as peanut cake powder, bone powder, calcium superphosphate and multi-element flower fertilizer, twice a month. Jasmine often has luxuriant branches and leaves but does not blossom in summer, the main reason is that too much nitrogen fertilizer is applied, resulting in the growth of branches and leaves. In such a situation, it is necessary to control fertilizer and water, increase the application of phosphorus and potassium fertilizer, and promote the gestation of flower buds. At the same time, we should pay attention to move the jasmine to a place with sufficient sunshine and good ventilation.

3, 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.

4. Soil: it is better to cultivate jasmine in fertile sandy and semi-sandy soil. When planted in slightly acidic soil with pH 6 to 6.5, the root system is dense, the growth is vigorous, such as clay weight, lack of matrix, low fertility and poor ventilation, the root system is less, the plant is short, the stem and leaf is slender, and the flowers are small.

5. Pruning: Jasmine grows very fast in summer and should be pruned in time. Potted jasmine pruning to retain the base 10 cm to 15 cm promotes the growth of most sturdy new shoots. If the new shoots grow very vigorously, they should pick the heart when growing 10 cm and promote secondary shoots, then they will bloom more and the plant shape is compact. After the flower withered, the flower branches should be cut off in time to reduce the consumption of nutrients, but also promote the growth of new shoots, so that the branches are dense, buds are more, and flowers are more.

6. Prevention and control of diseases and insect pests: Jasmine is often harmed by borer larvae and shell insects and red spiders, which is most serious from July to September. It often eats buds and can be sprayed with almighty powder or permethrin plus water 200 times every semimonthly, that is, no diseases and insect pests should be sprayed, so that the spraying time should be 9: 00 a.m. and 4: 00 p.m. on a sunny day, and should not be sprayed in the hot sun at noon to prevent drug pests.

Points for attention in jasmine culture:

1. Do not spray water on the flowers during flowering to prevent them from falling early and the fragrance from disappearing. Potted jasmine should be moved to shelter when raining.

2. potted jasmine flowers usually change their pots in about 2 years. When changing pots, you can put some bone powder and horseshoe powder in the basin as base fertilizer, and the appropriate time to change pots is in late winter and early spring.

3. Jasmine flowers only grow branches and leaves and do not blossom because of excessive application of nitrogen fertilizer or lack of sunlight. Therefore, when the jasmine enters the vigorous growth period, we should strictly control the application amount of nitrogen fertilizer and bask in the sun more, so as to prevent the plant from overgrowing.

Matters needing attention for jasmine culture 4. In winter, the jasmine should be placed in a warm and sunny place to avoid freezing damage to the plant. The whole plant can also be tightly covered with plastic bags, and a small hole at the top can also play a role in heat preservation, moisturizing and anti-freezing. Applying more phosphorus and potassium fertilizer can improve the cold resistance of potted jasmine.

5. Watering precautions: Jasmine likes acidic soil, and 0.2% ferrous sulfate is applied every 10 days during the growing period to keep the soil acidic. Proper water regulation of jasmine is the key to cultivation: Jasmine likes to be moist and afraid of stagnant water, and the basin soil is too wet and easy to rot roots and leaves and even die.

6. matters needing attention in fertilization: special attention should be paid to fertilizing jasmine in the process of cultivating jasmine. Generally, light bean cake water is applied every 7 days since May, and thin fertilizer should be applied frequently in the bud and flowering period, about every 5 days. Fertilization was stopped in October. Every rainy season in outdoor cultivation, instead of applying dry fertilizer, such as using bean cake powder (loose soil on the surface of the basin, add bean cake powder, cover with soil).

Is it easy to raise potted jasmine? points for attention in the cultivation of potted jasmine

Jasmine is a kind of flower with strong floral fragrance, and it has the function of repelling mosquitoes. Many families will raise it. Let's take a look at whether potted jasmine is easy to raise and the matters needing attention in potted jasmine breeding.

How to grow potted jasmine?

Culture methods of jasmine 1. Temperature requirements: the growth of jasmine is the most suitable when the temperature is 25 ℃ ~ 35 ℃. Adequate moisture and humid climate are needed throughout the growing period, and the air relative humidity of about 80% to 90% grows best. There is often a saying among the people that "immortal jasmine". If the jasmine is placed in a place that is too shady, it must not grow well, and the result can only be large leaves, sparse, few or no flowers, so the jasmine must be placed in sufficient light to grow.

Cultivation methods of jasmine 2, lighting requirements: Jasmine is a light-loving flower, which likes strong direct light during the growing period, and when the sunshine is more than 8 hours a day during the pregnant bud flowering period, the bud is full and white.

Cultivation method of jasmine 3. Soil selection: jasmine is particularly sensitive to soil permeability, so the permeability of slightly acidic water and fertility is good, and fertile sandy loam is the best. Potted jasmine should choose loose, fertile and slightly acidic basin soil, such as 5 parts of rotten leaf soil (or peat soil), 4 parts of garden soil and 1 part of cake fertilizer, and put a little bone powder on the bottom of the basin as base fertilizer. It is best to change the basin every year or every other year to replace the new soil. Watering thoroughly after changing the basin, and paying attention to loosening the soil, the temperature is kept between 22-24 ℃, which can accelerate the germination of new buds.

The cultivation method of jasmine 4. Fertilizer selection: jasmine is fond of fertilizer, which is suitable for the growth of fertile, loose and well-structured sandy soil and loam with PH value of 5.5-7. Normal growth of potted jasmine flowers, we should pay attention to pick the heart, remove too dense flower buds and old leaves. In order to blossom many times, every branch that has flowered must be cut off and let it fork again. As long as the fat water keeps up, it will soon blossom again. Sometimes jasmine flowers only grow leaves but do not blossom, the main reason is lack of light and too much nitrogen fertilizer. Because jasmine flowers should be exposed to the sun for at least 6 hours a day, and the branches that do not blossom should be treated at the same time; second, we should use less nitrogen fertilizer and more phosphorus fertilizer.

Points for attention in the culture of potted jasmine:

The main results are as follows: 1. Jasmine is a long sunshine positive plant and likes hot and humid climate. When the temperature is below 3 ℃, the twigs and leaves will suffer frost damage. When the lowest temperature is 0 ℃ and there is a slight frost, most of the leaves will fall off; at about 3 ℃ below zero, the branches will be in danger of freezing. For this reason, in places where there is frost in winter, it is necessary to do a good job in overwintering and keeping warm and controlling the moisture of basin soil.

2, when the temperature drops to 5 ℃-10 ℃, the jasmine should be moved indoors and placed in the sunny window; when the temperature is below 0 ℃, the potted flowers should be removed from the window at night to avoid the cold wind blowing through the window and freeze the jasmine; when the room is frozen, polyethylene film bags should be used at night to cover the potted flowers with the bottom and fasten the mouth of the bag, and then put the potted flowers in a warmer place. In order to avoid the danger of suffocation of jasmine, you can also poke a few small holes in the bag.

3. What if the jasmine leaves turn yellow? The first is watering. Sometimes the leaves of potted jasmine suddenly turn yellow, which is caused by root rot caused by excessive watering, so watering should be strictly controlled. Watering must pay attention to the climate, plant size, branch and leaf growth and flowerpot size and other conditions, basin soil is not too dry, do not water, not only to keep the basin soil moist, but also do not accumulate water.

4. Jasmine flowers grow rapidly, generally changing pots once a year, mostly indoors in April. Changing pots can be combined with ramets, but the root damage must be as little as possible. After changing the basin, it should be placed in a warm and humid place to promote its germination and growth as soon as possible. Peel off the buds in time.
