The cultivation method of jasmine: how to preserve jasmine? What if the jasmine only grows branches but does not blossom?

The main results are as follows: (1) Jasmine likes to fertilize the slightly acidic soil with loose soil and good drainage. Generally use 4 parts of pastoral soil, 4 parts of compost soil, 2 parts of river sand or grain bran ash, plus an appropriate amount of fully rotten poultry manure. Can also be self-made culture soil, garden soil and animal and plant raw materials layer by layer of soil in plastic bags, plus Amoy rice water compaction. After one winter, it can be made into culture soil. In order to keep the basin soil slightly acidic, 0.2% ferrous sulfate can be poured every 10 days or so. The basin should be changed for 3 years, which should be at the end of winter and the beginning of spring. There is no need to cut the root, replace it with new nutritious soil, and put some bone powder and horseshoe slices on the pelvic floor as base fertilizer to pour water through.

(2) Jasmine likes to be moist and breathable, and is afraid of stagnant water. If it is watered once every 2 or 3 days in spring, it will be thoroughly watered. The spring blossom period is from May to June, and the watering is a little more than that in the early stage. During the full flowering period from June to August, the sunshine is strong and water is needed, so it can be watered once in the morning and evening. In times of drought, spray the leaves and around the basin with water. In winter, it will not be dry or watered. Water thoroughly when the basin soil is gray and white.

(3) Jasmine likes light and is resistant to fertilizer, and potted plants must be placed in a sunny place. This is the reason why the flower proverb says "immortal jasmine". If the sun is not enough, it is easy to grow, resulting in sparse leaves and affecting the flowers. Jasmine likes fertilizer, especially at flowering stage. Families can use kitchen leftovers to add black alum retting liquid fertilizer. The principle of frequent application of thin fertilizer should be grasped in fertilization.

(4) be careful not to apply fertilizer when the basin soil is too dry or too wet, and the effect of fertilization is the best when the basin soil is dry and non-dry. If jasmine only grows branches but does not blossom, it is due to excessive nitrogen fertilizer and lack of sunlight, such as more phosphorus and potassium fertilizer, more sun exposure, it is generally not difficult to bud and blossom.

(5) at the end of winter, four pairs of old leaves are retained on each branch, and the rest are cut off, but do not damage the buds in the leaf axils. Jasmine generally grows five batches of branches in a year, the first batch is strong, the second batch is second, the third batch is again and again, and the fourth batch and the fifth batch are thinner and weaker, so they should be cut off. The flower proverb says: "Jasmine is not pruned, but it is obvious that the branches are weak and the flowers are small."the pruning must be ruthless and the blossoms will be stable." The buds of new shoots should be picked around the end of May. As the temperature is slightly lower at this time, the lower part of the cut can produce a number of new branches and blossom. At this time, each batch of buds are the size of mung beans, and when the first flower is white, it will not be watered temporarily. Make the pot soil dry, wait for the plant tender leaves and buds to droop before watering, so that nutrients and water can be concentrated to supply flower branches and make jasmine bloom more. With reasonable water and fertilizer management, jasmine can blossom all over the branches.

Conservation methods of potted jasmine and how to maintain jasmine pot cultivation in the north

Flower bonsai network guide: today, Flower Bonsai Network is about the conservation methods of potted jasmine flowers, and how to maintain jasmine potted plants in the north. Friends who like jasmine flowers come and have a look.

I believe that many flower friends have raised their beloved jasmine, the daily maintenance of jasmine is extremely important, and many flower friends do not maintain properly, resulting in dead branches and fallen leaves of plants, seriously affecting the beauty of jasmine, so how to preserve potted jasmine?

Potted jasmine: in midsummer, water should be watered early and late every day, such as dry air, need supplementary spraying; during winter dormancy, the amount of water should be controlled, such as the pot soil is too wet, it will cause rotten roots or 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.

Selection of potted jasmine soil

The soil of jasmine needs loose, fertile and slightly acidic soil with good drainage. It is generally made by mixing garden soil, river sand and mature fertile soil. In order to keep the soil slightly acidic, ferrous sulfate can be irrigated every 10 days or so.

The 2-3-year-old jasmine needs to change the basin, and the jasmine root is too long in the soil, which affects the normal nutrient demand of jasmine. If the pot is not changed properly, the jasmine will stop growing. It is best to set the time to change the basin before Jasmine comes out of the room. Jasmine change pot do not trim the root, replace the new culture soil and water it.

How to water potted jasmine

Jasmine flowers like wet growth environment, but afraid of stagnant water, need more watering during hot and hot summer, but too much will lead to plant growth stop, basin soil stagnant water.

Spring watering should be watered every 2-3 days, watering around noon, dry and wet, dry and then watered thoroughly.

At the first flowering stage, there is a little more watering. Enter the summer high temperature, also is the jasmine growth prosperous period, at this time the light is strong, should carry on the watering, in the morning and evening 10 each time.

The last florescence in autumn is about September-October, when watering is reduced for about 2 days, and the amount of water is strictly controlled in winter, otherwise the basin soil will be moist and the temperature will decrease, which is seriously disadvantageous to the growth of jasmine.

How to fertilize potted jasmine

Jasmine likes fertilizer, especially its florescence, but the amount of fertilizer should not be too much, and the principle of thin fertilizer should be grasped. Fertilization should be based on light fertilizer, once a month, too much fertilizer will lead to leaf withering and yellowing.

Teach you how to maintain jasmine pot planting in cold winter

Jasmine belongs to the sun-positive flowers and trees, afraid of low temperature and severe cold, once the frozen leaves are easy to fall off from frostbite, and then endanger the branches and even the trunk. Domestic potted jasmine has poor heat preservation because of the thinner soil layer around its roots, so when the weather forecast has a low temperature, it is necessary to move the outdoor jasmine to a shelter in time.

The jasmine under low temperature and cold should be maintained as dry as possible-see that most of the basin soil is dry, and watering should be carried out at noon when it is sunny.

Jasmine is afraid of low temperature, frost and cold wind during the winter. at the same time, it is necessary to breathe and bathe in the sun, and to prevent plants from drying and damaging branches and leaves due to lack of water. These conservation elements, we should seize the opportunity to grasp and implement flexibly according to the change of air temperature and the physiological (dry and wet) response of jasmine plants (branches and leaves), especially when replenishing water to the basin soil. That is, the edge of the basin soil (the shrinking joint between the basin soil and the basin edge) is obvious, which is the reaction that the jasmine plant needs to replenish water. At this time, it is not urgent to wait for the sunny noon or so. Give it [slightly apply warm water without ice hands]-- the basin soil can be moist a little, and the watering should never be excessive, because the jasmine plant at low temperature is weak and does not require much water. Too much watering can easily cause rotten roots and cause plant leaves to fall off and die.

The period from the Winter Solstice to the Beginning of Spring in the lunar calendar is the coldest period in winter. Jasmine should pay attention to shelter from the wind-prevent branches and leaves from dying; pay attention to daylighting-- to benefit the light and circulation of branches and leaves to resist the cold, and at the same time consider plant ventilation-- which is beneficial to the respiration of branches and leaves and roots, so as to avoid the symptoms of branches and leaves and withered branches and leaves caused by jasmine in an impermeable environment.

After the the Beginning of Spring of the lunar calendar, the temperature changes abnormally, cold and heat occur from time to time, so it is very important to prevent the late spring cold from the Beginning of Spring to the Qingming Festival. Many jasmine plants have survived the severe cold. However, the important reason why it is difficult to avoid the late spring cold is-- moving away from the wind shelter too early when heating up-- cold and heat as easily as people, with less air permeability-- stuffy branches and leaves lose normal light and circulation. Too much daylighting-- scorching weak branches and leaves, too much watering-- leads to rotting roots. Another important reason is that the jasmine plant is pruned too early. If the jasmine plant is not in a state of germination, it is very easy to cause the sitting pole-the branches wither down from the pruning place, and even endanger the trunk and finally cause the whole plant to wither. During the period from Qingming Festival to Grain Rain, the temperature tended to stabilize after rising, and the branches of jasmine sprouted slightly. It was a good time to prune and move the jasmine to the flower rack for normal maintenance.

The north pot jasmine flower conservation method, the preparation of culture soil, jasmine like fertilizer fertile loose, well-drained slightly acidic soil. Generally use 4 parts of pastoral soil, 4 parts of compost soil, 2 parts of river sand or grain bran ash, plus an appropriate amount of fully rotten dried cake, chicken and duck manure, etc. Can also be self-made culture soil, garden soil and animal and plant raw materials (such as vegetable leaves, branches and leaves, melon peel, feathers, fish viscera, etc.), according to a layer of soil layer of animal and plant raw materials preparation in plastic bags or flowerpots, plus Amoy rice water compaction. In this way, after a winter, a kind of soil suitable for jasmine cultivation can be made. In order to keep the basin soil slightly acidic, 0.2% ferrous sulfate can be poured every 10 days or so.

After growing for 2 to 3 years, the root system of jasmine is intertwined in the basin soil, and the physical and chemical properties of the cultivated soil become worse. If the jasmine is not changed, the growth of jasmine will be seriously affected. It's better to change the basin before Jasmine comes out of the room. When changing the basin, generally do not trim the root, replace it with new nutritious soil, and put some bone powder and horseshoe slices on the bottom of the basin as base fertilizer, and pour water thoroughly after changing the basin.

Watering properly according to the characteristics of jasmine like moist and afraid of stagnant water and air permeability, we should grasp the principle of watering. From April to May in spring, jasmine is drawing branches and spreading leaves, the temperature is not high, the water consumption is not large, and it can be watered once every 2 to 3 days, before and after noon. If you want to see dry and wet, watering must be thoroughly watered. The spring blossom period is from May to June, and the watering is slightly more than that in the early days. June to August is the summer day, the temperature is the highest, is also the peak period of jasmine blooming, strong sunshine, need more water, can be watered once in the morning and evening. In times of drought, water is also used to spray the leaves and the ground around the basin. From September to October, it can be watered once every 1 to 2 days, and the amount of watering must be strictly controlled in winter, otherwise the humidity of the basin soil is too high and the temperature is too low, which is disadvantageous to jasmine overwintering. As far as the principle of watering during the growing period is concerned, it should not be dry or watered, and the pot soil should be watered thoroughly when the soil becomes gray and white.

Appropriate amount of fertilization jasmine likes fertilizer, especially the long flowering period needs more fertilizer. Families can rett with kitchen leftovers to make liquid fertilizer. Such as fish offal, rice water, bean cake, add black alum (ferrous sulfate) into the water tank, in the sun for 20 days or so can be used. The fertilizer and water prepared in this way can not only meet the needs of jasmine for fertilizer and water, but also change the pH of the soil.

Just out of the house after fertilization, fertilizer liquid should be light, applied once a week, the ratio of fertilizer to water at 1:5. Fertilization after bud and anthesis, the ratio of fertilizer to water should be 1:1. Fertilization should be applied every 4 days when the high temperature is in full bloom, you might as well fertilize it in the morning and in the evening, and dissolve the water the next day, which is beneficial to the absorption of jasmine roots, and should be applied less or stopped before Frosts Descent to improve the maturity of branches to survive the winter. Fertilization time can be flexibly mastered, generally in the evening, before application, first use a small shovel to loosen the basin soil, and then apply. Be careful not to apply fertilizer when the basin soil is too dry or too wet. The effect of fertilization is the best when the basin soil is dry and not dry. The phenomenon that jasmine only grows branches and leaves but does not blossom is mainly due to excessive nitrogen fertilizer and insufficient sunlight, such as applying more phosphorus and potash fertilizer, and basking more in the sun according to the habit of enjoying light, it is generally not difficult to conceive buds and blossom.

Pruning branches and leaves jasmine is usually pruned before going out of the room every year when changing pots.

Specific method: after waiting for the basin soil to be dry, except for keeping 4 pairs of old leaves on each branch, the rest of the leaves will be cut off, but we should be careful not to damage the young buds in the leaf axils. Jasmine generally grows five batches of branches in a year, the first batch is stout and powerful, the second batch is followed by the third batch, and the fourth batch and the fifth batch are very weak. Thin and weak branches should be cut off because they cannot produce a large number of buds, waste nutrients and affect light transmittance.

How to make jasmine blossom?

First of all, do a good job of picking buds. Around the end of May, the new shoots are emerging and then the buds are pregnant for the first time, because the temperature is slightly lower, the temperature difference between day and night is large, the buds are stunted, the flowers are small, and the aroma of flowers is poor. In order to promote more new shoots to produce more and better buds, these weak buds should be cut off in time at the third pair of leaves, and the top of the branches with only leaves but not buds should also be cut off. In this way, the lower part of the cut can usually produce a number of new branches to achieve the purpose of multi-flowering. At this time, each batch of flower buds can be the size of mung beans, in which the first flower is just white, do not water temporarily, make the pot soil dry, and water again when the plant tender leaves and flower buds droop, so that nutrients and water can be concentrated to supply flower branches and make jasmine bloom more. Do a good job of the above points, coupled with reasonable water and fertilizer management, your jasmine will be full of flowers.

1. Flood: Jasmine has shallow roots and developed fibrous roots, luxuriant branches and leaves, high temperature and evaporation in summer, and it is not resistant to drought, so the soil can not be too dry, but it should not be muddy. Pots had better use soil basins, plastic pots, porcelain pots with poor air permeability, can be used as a cover basin. The premise of flood is that the soil aggregate structure is good, loose and ventilated. The principle of flood irrigation is to dry and wet, dry and thoroughly irrigate. Note that dryness is by no means dry coke.

2. Big fertilizer: Jasmine has long growth cycle, large annual growth and repeated branches and blossoms, fast nutrition consumption, high energy demand, thin branches and thin leaves and less flowers if the fertilizer can not keep up with it. The premise of big fertilizer is mainly rotten organic fertilizer, which is extremely important, such as rapeseed cake water (topdressing), poultry and fish visceral water (topdressing), supplemented by chemical fertilizers such as potassium dihydrogen phosphate. The method of fertilization is to apply it in the evening on a sunny day during the growing period, return water in the early morning of the next day (crucial), and once a week during the growing period.

3. High-temperature exposure: Jasmine likes the sun very much and must not over-shade. Under the premise of ensuring moisture, full-day sunshine is the best. If there is sufficient sunshine, there are many flowers with luxuriant leaves and leaves, while low-temperature shading means thin leaves, thin flowers and thin branches. In addition, moderate pruning before spring germination and after each batch of flowers can ensure proper density of branches, concentrated nutrition and reduce ineffective consumption.

Supplement: the problem of strengthening in the process of maintenance. After five years of growth, the main branches will age, the upper branches will be thin and weak, and the flowers will be small. In the meantime, special attention should be paid to cultivating more native branches at the base, which are strong and properly guided to the old main branches that need to be renewed. after a year of growth, the old branches can be replaced and the soil surface of the old branches can be cut off, so as to achieve the purpose of renewing the main branches and strengthening the trees. maintain vitality.

Soil selection: it is better to cultivate jasmine in rich sandy and semi-sandy soil, and in slightly acidic soil with pH value of 66.5.

The main pests during the growth period of jasmine are jasmine leaf borer, cotton red spider, bran shell insect and so on.

1: Jasmine leaf borer: it is one of the main pests of jasmine. It eats the leaves, buds, twigs and shoots of jasmine with its larvae. The bark of branchlets withered after being eaten, and the seedlings died after being killed, which seriously affected the growth and flowering of jasmine.

Control methods: ① winter or early spring, remove the withered branches on the plant and leaves on the ground, concentrated burning; ⑧ properly thinning leaves to facilitate ventilation; timely manual capture and kill eggs, larvae and pupae on the leaves. During the growth of jasmine, ② can be sprayed with 6000 times of 50% trichlorfon wettable powder, which has a good control effect.

2. Cotton red spider. It can harm many flowers and many greenhouse plants. Jasmine is one of the common victimized flowers. The leaves of the injured flowers showed small yellow-white spots at first, then gradually turned red and extended to the whole leaf, resulting in leaf curl, withered and yellow shedding, rapid reproductive development and serious harm, affecting the growth and flowering of flowers and trees.

Control methods: in the red spider harm period, you can use 1500-2000 times of trichloropropanol EC (1500-2000 times of trichlorotrichlorohydrin wettable powder, or 1000-1500 times of omethoate) spray control, spray once every 7 days, spray 2-3 times, the effect is better. When spraying, you should spray on the back of the leaves, and pay attention to spraying the inner branches and leaves of the middle and lower parts of the plant.

3. Bran scale beetles: 4 generations occur from May to October, the larvae and nymphs can crawl, and the adults are fixed in a waxy shell to absorb tree sap. Prevention and control methods: the nymphs and nymphs can be fully sprayed with contact insecticides such as dimethoate and other contact agents in the nymph stage. Because of the waxy shell, the adults should be killed by internal inhalation drugs such as omethoate and No. 20 petroleum emulsion which can dissolve the wax shell.

In addition, jasmine should be pruned in the process of growth, especially in summer, jasmine grows very fast, so it should be pruned in time. Potted jasmine pruning to retain the base of 10 cm to 15 cm, to promote the majority of stout shoots. 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.

Key to conservation of potted jasmine in autumn and winter

Don't prune the jasmine.

In autumn and winter, jasmine will be in a dormant state, at this time the absorption of the share is relatively limited, and the demand for nutrients is maintained by the nutrients stored in the branches, so in the autumn and winter season, potted jasmine had better not be pruned too much and cut off a large number of branches, which will not be conducive to its winter.

Water jasmine flowers should be controlled.

In autumn and winter, when the temperature is low and the light is not strong, the jasmine is dormant, the root growth slows down, and the plant growth weakens, and the watering time needs to be properly prolonged. The main thing is to keep the pot soil of jasmine in a dry state to prevent it from being frozen and rotted. At the same time, new semi-lignified branches may become woody before the cold winter, which can improve the ability to resist freezing.

Stop fertilizing jasmine

Similarly, in the autumn and winter season, because the plant dormancy, the need for nutrients has been reduced, and at this time the root activity decreased, the ability to absorb nutrients weakened, so it is necessary to stop fertilization. If fertilizing is carried out at this time, it may cause fertilizer damage to the jasmine and rot the roots easily.

The jasmine enters the room at the right time.

In autumn and winter, jasmine needs to enter the house in time to avoid freezing damage, but you need to master the time to enter the house. Don't be in too much of a hurry. You should let the jasmine slowly adapt to the change of temperature. Don't rush into the room at once. This will make the jasmine adapt to the temperature.
