Culture methods and matters needing attention of Jasmine Flower

The jasmine is fresh and elegant, and the flowers are beautiful, which can be used not only to watch but also to make tea. many people want to raise jasmine on their own, so what should they do when raising jasmine? Are there any methods and precautions? Next, let's learn more about it with the editor of the decoration network.

Culture methods and matters needing attention of Jasmine Flower

Culture methods of jasmine flowers

1. Environment and light: 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. 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.

Matters needing 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.

4. Put the jasmine in a warm and sunny place in winter to avoid freezing damage to the plant. You can also use a plastic bag to cover the whole plant, and cutting 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).

How to raise jasmine, the methods and precautions of jasmine culture / basking in the sun

Jasmine, needless to say, we must have seen, it is a more common potted flowers in life, the biggest feature is undoubtedly its pure white color. Generally speaking, how to raise jasmine is the same as other plants, but there are different points to pay attention to in the process of growing jasmine. The following are the breeding methods and matters needing attention of the jasmine arranged by the editor, which is very comprehensive. We might as well take a look at the cultivation mentioned in it.

First, how to raise jasmine, sunshine and watering

Generally speaking, the culture method of jasmine is relatively simple compared with Phalaenopsis, peony and other flowers, but it still takes some effort to plant jasmine well and prolong its flowering period. Light, watering, temperature, soil and so on are all we need to pay attention to, and then we will talk about them in detail.

II. Culture methods and matters needing attention of jasmine flowers

1. Loose soil

In the cultivation of jasmine, the most important thing to pay attention to is the soil. Jasmine is particularly sensitive to soil permeability, so it is more suitable to choose loose soil, which is easier for flowers with less developed roots such as jasmine.

Note: the alkaline basin soil will cause the leaves to turn yellow. When the leaves turn yellow, thin alum fertilizer can be applied every 5-7 days, and soon the yellowed leaves on the plant can change from yellow to green and gradually return to their original state. After that, it can be combined with fertilization, applying dilute alum fertilizer and water every 7 to 10 days, which can keep the leaves fresh green and grow normally.

Soil selection: 5 parts of rotten leaf soil (or peat soil), 4 parts of garden soil and 1 part of cake fertilizer were mixed, and a little bone powder was put 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.

2. The light should be sufficient.

Jasmine is a light-loving flower, which likes strong direct light during the growing period. when the sunshine is more than 8 hours a day during the gestation and flowering period, the buds are full and white. So as long as it is daytime, flower friends should put it outside to receive enough light, but if it is midsummer, do not expose it to the sun.

Note: if the light is not enough, the branches and leaves of jasmine will jump, the color of the leaves is light, the branches are thin, the flowers are few, and the aroma is light. Therefore, in order to ensure sufficient light, it is a good choice to place jasmine on the balcony or roof.

3. Watering should be diligent

Because planting jasmine is suitable to choose loose soil, this kind of soil has good drainage, so we should pay attention to it when watering. Water must be thoroughly watered until the water has just seeped out of the bottom of the basin. But that doesn't mean it's enough. Florists are guaranteed to water at least twice a day, preferably once in the morning and once in the evening.

Note: once the jasmine is not watered enough, the jasmine will not grow well, and the leaves will be yellow and rare, so flower friends must water them frequently. As for when to water, there are two ways: ① looks at the pot soil to see if it is dry and wet, and whether it is dry or wet; ② taps his fingers on the flowerpot to listen to the sound, which means that the pot soil is dry, and his muffled voice means that the pot soil contains water.

4. Temperature: 25 ℃-35 ℃

Jasmine is a positive plant with long sunshine, and it is the most suitable for growth at 25 ℃ ~ 35 ℃. 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 are in danger of freezing, so the jasmine must be placed in a place with high temperature to grow.

Note: 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, lest the cold wind blow through the window and freeze the jasmine; when the room is frozen, at night, polyethylene film bags should be used to cover the potted flowers with the bottom and tie the mouth of the bag tightly, 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.

5. Rational fertilization

Jasmine is fond of fertilizer and is suitable for the growth of fertile, loose and well-structured sandy soil and loam with a pH value of 5.5-7. However, less nitrogen fertilizer should be applied at flowering stage, because the effect of nitrogen fertilizer is to promote leaf growth, too much nitrogen fertilizer will make jasmine branches and leaves grow luxuriantly but do not blossom, so nitrogen fertilizer is more suitable for seedling stage. During the flowering stage, the application of organic fertilizer will be more effective, which can promote flowering and prolong the flowering period.

Note: sometimes jasmine flowers will only grow leaves but do not blossom, the main reason is lack of light, and second, 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.

6. Pruning frequently

In the cultivation method of jasmine, learning to prune is a very important link. Necessary and appropriate pruning of jasmine can not only ensure the storage of nutrients of jasmine itself, facilitate the growth of new branches and the germination of new flower buds, but also ensure the beauty of the tree shape, but also make use of the cutting propagation of strong branches under pruning to ensure the replacement of new and old jasmine.

Note: when the day is right, jasmine grows rapidly and has luxuriant branches and leaves. If the new branch grows too fast and slender, the 10CM should be cut off from the branch to promote more lateral branches to grow.

7. Change the basin reasonably

It is necessary to change the pot of jasmine which has been planted for more than 2 years. At this time, the roots of jasmine have been entangled and confused, and the ability to absorb water and air has been greatly reduced. Loosening the soil alone can no longer solve practical problems. Change a larger flowerpot and match it with loose soil to make jasmine coruscate its second spring.

Note: when the jasmine flowers planted in the pot grow up from small to small, and the roots cover the whole basin, the plant needs to change from the small pot to the large pot. Generally, before the jasmine sprouts, the root system is pruned and then a larger basin is replaced.

8. Pest control

Jasmine is a flower that is not susceptible to insect pests, but it is necessary to take some necessary precautions if you want to bloom well. Red spider is one of the common pests when planting jasmine, and the corresponding insecticide is easy to buy, which is introduced in the pest control of potted jasmine.

Note: when spraying liquid, do not just focus on spraying jasmine leaves and flowers, the soil must also be sprayed, otherwise pests will not be completely cured. For infected leaves, they should be removed in time.

Culture methods and matters needing attention of Jasmine Flower

The cultivation methods and matters needing attention of jasmine is a more comprehensive article on jasmine culture, which is the experience of jasmine conservation in the past 30 years. It is worth reading and learning for those who like jasmine. The article involves jasmine watering, fertilization, pruning and other important links.

I. the culture method of jasmine-watering

Planting jasmine, learning to water is considered to be the door of growing jasmine. The jasmine cultivated by many people does not grow well, such as yellow leaves, sparse leaves, few or no flowers at all, or no winter at all, and the following year will either wither or grow more unseemly, more unshaped, and so on.

The above symptoms show that: first, usually inappropriate watering, mainly do not know which season should be watered more, which season should be watered less, there are more watering seasons, how to water by stages in a day, and how to water less in the less watering season? How to observe whether it needs watering and so on.

These are certain technical content and meticulous maintenance links, too much watering jasmine is easy to rot the root, the layman often can not see whether its root is rotten, still think that the watering is not enough, still think that malnutrition, give it fertilizer, this will kill the jasmine! Watering jasmine less generally won't kill it. Flower cultivation proverb: "dry jasmine, wet chrysanthemum." this is a summary of the experience of flower growers since ancient times, so it is said that learning to water jasmine is the door to growing jasmine.

How to grasp watering:

1. If you look at the basin soil, you can see whether it is dry or wet, and whether it is dry or not.

2. Fingers tapping on the flowerpot to listen to the sound, clear and sweet means that the pot soil is dry; the muffled voice indicates that the pot soil contains water.

Usually, broken pots are placed at the bottom of the flowerpot to facilitate drainage and ventilation. The foam block used as a basin floor pad is a new material, and it can also be regarded as a new thing, which can not be defined by good or bad. Just like the original wound was bandaged with hemostatic powder and gauze, with a band-aid, people apply it for the same reason.)

Second, the culture method of jasmine-- fertilization.

There are three elements of plant growth: "soil, sunlight and water". With the three elements, plants can survive and grow. So if plants want to grow sturdy, luxuriant branches and leaves, flowers and fruits rich, we must know that the three elements of plant nutrients: "nitrogen, phosphorus, potassium". The same is true of growing jasmine, we must understand these two "three elements". Often beginners who grow jasmine do not understand the essence of the "three elements" of nutrients needed by plants, and easily fertilize jasmine. This not only fails to achieve the effect, but is counterproductive, making the jasmine that can grow worse and worse.

Learn to fertilize jasmine, then you will go from the initial stage of growing jasmine to an important maintenance stage in the next step. If you fertilize jasmine properly, it is self-evident that jasmine will blossom and grow luxuriantly, strong branches and moderate tree shape, so that there is no need for the owner to worry about the functions of disease and disaster resistance, cold resistance and heat resistance.

Why can't family pot-raised jasmine be fertilized in a hurry in spring and early summer?

(1) many Taoists are more concerned about this problem, but often after listening to the words of the florist or the introduction of the Internet or books or magazines, they seize the opportunity to fertilize jasmine at home. I hope that after receiving fertilizer, my jasmine can grow faster, blossom more, branches stronger, etc., the result is either wrinkled leaves, thin leaves, or only long branches and leaves without many flowers. At this time, the owner still thought that jasmine was short of fertilizer and constantly applied all kinds of fertilizers to it, but the result was still unsatisfactory, thus hurting the confidence of protecting jasmine, which is the reason why it is not in a hurry to apply fertilizer.

(2) fertilization must be under the condition that the basin soil is dry, and it should be carried out from afternoon to evening. General family maintenance of jasmine should not be fertilized in the morning or noon, and a small amount of water should be poured to the fertilized ML the next morning, which is called watering [backwater]. This link is very important and is the key to whether jasmine can absorb the fertilizers. The best way to apply fertilizer is to compost ripe human manure, followed by potting cake fertilizer (soybean cake and sesame cake) water, and again (without conditions) is chemical granular fertilizer, the method is to loosen the soil at the edge of the basin slightly, put it into granular fertilizer, press the pot soil and pour clear water, generally about 5 inch flowerpot can be put about 15. Granular fertilizer in my early years (around the 1990s) used Zhenjiang "Fei Hua Dan" effect is OK, I do not know whether it is sold now. Remember the time after applying this kind of granular fertilizer, apply it on time according to the instructions, and keep in mind that no fertilizer should be widely used. Jasmine likes compost most, but it is not easy for families to raise jasmine. Generally, they use bean cake and sesame cake to mash, soak, soak and mix with water, or soak with eggshell to soak and apply with water. Those without conditions have no choice but to apply granular fertilizer containing phosphorus and potassium after germination of flower buds. Pay attention to the application of nitrogen-containing granular fertilizer as little as possible, otherwise it will be difficult to nurture flower buds only with long leaves.

(3) as the temperature rises gradually after the Dragon Boat Festival, there is a saying in Wuhan: "give your cotton-padded clothes after eating salt egg dumplings" means that there will be no more "cold wave". The period from Dragon Boat Festival to Mid-Autumn Festival is usually called the blooming period, and the flowers blooming in the summer summer are called summer flowers. Professional florists have the saying that "head-volt flower season, two-volt flower season, three-volt flower season", which means blooming like a tide in this blooming season. The same is true of the magic of family care, during which flowers are pleasing to the eye and fragrant. People must not neglect the care of each flower when it is in full bloom. It is only a day and a night before the flowering period of each flower. After flowering, you should cut off the residual flowers in time, give nutrients to other flowers, and build them step by step. After a batch of flowers are all in full bloom, prune the branches in time according to the shape of the flower tree and personal wishes, waiting for them to sprout new branches and then give birth to new buds. Once new buds are found, they will form. It is necessary to apply fertilizer and water in time, and the frequency of fertilizer and water should increase with the increase of the bud. It is the principle that the pot soil is too wet to fertilize. Only when the jasmine is budding, people want to enjoy the flowers to avoid the smell and stop applying them.

Third, the culture method of jasmine-- pruning.

To plant and cultivate jasmine, learning to prune is a very important link. Necessary and appropriate pruning of jasmine can not only ensure the storage of jasmine's own nutrients, facilitate the growth of new branches and the germination of new flower buds, but also ensure the beauty of the tree shape. cutting propagation of strong branches can also be used to ensure the replacement of new and old jasmine.

Nursing points of jasmine in early spring:

[picking leaves] during the period from Qingming Festival to Grain Rain, the temperature gradually rose and the branches of jasmine began to germinate. at this time, all the old leaves on the branches of jasmine should be picked off in time. These old leaves have been completed, the historical mission of storing nutrients to keep jasmine safe through the winter, and its photosynthetic cycle function is basically damaged. Keeping them not only hinders the daylighting of jasmine branches, but also consumes the limited nutrients left in jasmine branches after winter, so it is necessary to pick all the old leaves on jasmine branches before sprouting, that is, before Qingming.

Picking all the leaves for jasmine is the experience of conserving jasmine for many years. For those old leaves that have gone through last year and winter, their photosynthetic cycle function has basically been damaged to the utmost. For those who first raised jasmine, it seems that the green branches and green leaves are very beautiful, but in fact, these old leaves are left on the branches of jasmine, which is a great harm to the jasmine itself:

[first] these old leaves are left on the branches of jasmine, when jasmine has not yet returned to normal function in early spring, especially when the root system of jasmine has not fully restored the function of absorbing nutrients from the soil. However, they are the first to absorb the limited nutrients in the branches of jasmine and retain very little nutrients after a winter. Straight segments affect the germination of new buds of jasmine, causing the germination of new buds to lag or underdevelop, thus affecting the formation of flower buds. Often many people maintain the jasmine in the first year is in full bloom, and then the next year is not as good as a year just do not understand this point.

[second] these old leaves stay on the branches, straight nodes affect the lighting of jasmine branches, and then affect the germination of new buds of jasmine and, more importantly, the formation of flower buds in the new buds. The flower buds of jasmine are formed in the new buds, and those old leaves are left on the branches, which can not help the jasmine carry out photosynthesis, make the nutrients in the branches of jasmine circulate normally, and constantly absorb the nutrients that should be used for the growth of new branches, leaves and flower buds. In this way, how can the preserved jasmine grow stronger and stronger year by year?

[pruning] after sprouting the new bud, the orientation of the new bud extension was selected, and yesterday the new bud was shaped and pruned.

After the Qingming Festival, the temperature gradually picked up and more stable, the pruned jasmine can be placed on the flower rack for maintenance.

The experience summed up over the years: do not rush to change the pot in spring, wait for the first stage of flowers to bloom, and then change the pot. Its advantage is that it happens to have a period of rejuvenation and sprouting after blooming, during which the temperature is relatively high and relatively stable. The jasmine root system moved during the basin change is easy to recover.

The nursing care of jasmine in spring is mainly to cut off the old branches and leaves, prune the old and weak branches, and set the pruning. In addition, there is another important nursing point that is not known to the public, that is, the tip of the new bud is removed, and a large part of the new buds germinated are only long branches. This kind of branch generally does not germinate flower buds. If it is not removed in time, it not only affects the shape of flowers and trees, but also absorbs a large amount of nutrients in the basin, which is not conducive to the germination of flower buds, so it must be removed in time.

The flower buds conceived in this season (April) are called "Sui Niang Flowers". In order to make the jasmine stronger, it is generally necessary to remove the jasmine. After removal, it is very beneficial for it to bloom in summer. People often only care about a little flower bud in front of them, while neglecting the long-term love and maintenance of flowers and trees. The reason that the new leaves are not green is that the mother flower absorbs a lot of nutrients. It is up to the florist to prune more or less of the flowers. If you want the branches of flowers and trees to be strong and blossom more in the future, you should trim them all. If you want to appreciate the flowers in your flowerpot at that time, you can not cut the flowers, but not trim them. These flowers will absorb a lot of nutrients from the trunk and affect the sprouting of new branches and flower buds. This is a knock-on effect of Sui Niang Flower. The so-called "Sui Niang Flower" is a unique flower bud in an abnormal state among the characteristics of jasmine, which germinates earlier, less and less fragrant. Professional flower growers all know that Suiniang flowers must be pruned before jasmine can achieve high efficiency and high yield. These are the experiences summed up by people, which are rarely published in theory, and are often difficult to be understood.

Pick the top according to the shape of your favorite flowers and trees. You can take a closer look at the top jasmine in my pot, usually from the first or second section of the branch (that is, the root up the first pair of petioles or the second pair of petioles). Not to pick the top at will!

[several key points] (1) Ferrous sulfate cannot be applied at will, do not listen to the promotion of flower fertilizer, the leaves of jasmine will turn yellow after the potted soil is too alkaline, which shows that it is necessary to supplement acidic elements, and people using ferrous sulfate will be counterproductive at that time. There are bad phenomena such as rotting roots and burning to death. In fact, they have raw materials to supplement acidic elements-rice washing water. Amoy rice water left into the empty high orange bottle, let it fully ferment spare, when needed, take a small amount of water to immediately supplement acid elements, both economical, affordable and relatively safe.

(2) keep it outdoors in the sun, not indoors or in a dark place.

(3) pruning after flowering according to your favorite tree shape, there is no definition, pruning skills need to be summed up slowly.

(4) the height of the branches retained when pruning should be determined by the shape of flowers and trees, or by the shape of flowers and trees that one likes, for example, some people like to be tall and strong (growing upward, giving priority to the middle trunk, partial branches as a supplement), some people also like to be dwarf (the tree shape is shorter and stretches around, partial branches are mainly, the middle trunk is oriented pruning), you can't cut or retain a few sections as a whole.

(5) intentionally or unintentionally, part of the root system will be damaged more or less when changing the basin, so [do not rush to apply fertilizer]. If you apply fertilizer (no matter what fertilizer), people generally cannot see the rotten root of jasmine. However, from the surface phenomena such as: growing well before changing the basin, not many new buds sprouting, no flower bud germination and so on, we can see that the root system has been damaged. People often misunderstand it as: lack of fertilizer, lack of water, lack of what, constantly add fertilizer and water to it, the result is more and more bad, and finally end up with the loss of confidence in the conservation of jasmine. Generally, when changing the basin, put an appropriate amount of ripe cake fertilizer at the bottom of the basin, and cover up the fertilizer with basin soil, so that the root system can not be directly glued to fertilizer to avoid rotting roots. Normal watering and fertilization management can be carried out after changing the basin for 2 to 3 weeks.

(6) the lack of water in flowerpots on sunny days is easy to see from the leaves, and it is generally difficult to identify the lack of water in flowerpots on cloudy days, as well as the size, light and shade tolerance of flowers and trees, large flowers and trees consume a large amount of water, while small flowers and trees consume a lot of water, while light-resistant flowers and trees consume a lot of water, while shade-tolerant flowers and trees do the opposite. The top leaves first knock on the flowerpot with their fingers and listen to the sound of the flowerpot. If the sound is clear, it means the pot soil is dry, and if the sound is stuffy, it means the pot soil contains water. Sometimes it may be that there is something wrong with the root system of this flower and plant, and the more you water it, the more it will make the leaves grow.

The flowers and trees that have just changed pots should be put in a cool and ventilated place outside, usually within 1-3 days at most. Or put it in a place where you can't see the sun (that is, do not bask in the sun) for 1-3 days to maintain it normally.

(7) any flowers and trees in new pots or new pots (including jasmine) cannot be directly exposed to the sun, but are generally placed in a place where the sun is avoided-where the sky does not see the sun, for 3-5 days, the aim is to restore the vitality of the roots that have been moved, the absorption function of the roots is normal, and the branches and leaves of the flowers and trees are responsive, and then they can be placed in the sun for maintenance. Three elements of plant growth: soil, water, sunlight, all of which are indispensable.

(8) it was found that the jasmine leaves were crumpled in spring. First, fertilization was too early. Second, the light of the cultivation site is too little. Third, watering is too frequent.

(9) the basin soil is taken according to its own conditions, and it is best to dry the jasmine with [lotus pond mud] under the conditions, and then there is the old vegetable garden soil-oil sand. The quality of the soil should not only keep moisture but also have good water permeability, which requires that it is not dry and not white, and wet and not muddy.

IV. The culture method of jasmine-- the management in early summer

In early summer, the temperature gradually rises and is relatively stable, and the branches and leaves of jasmine grow vigorously. When the temperature reaches more than 30 degrees Celsius, it will sprout flower buds. The key management points are as follows:

(1) the jasmine placed on the balcony flower rack for maintenance, during this period, pay attention to often (once a week) to change the direction of the flowerpot, so that the jasmine will always grow in the same direction and grow in a crooked tree. this conversion of flowerpots can also make jasmine branches evenly bathed in the sun and better sprout new branches and flower buds. The flower buds of jasmine are conceived in new branches.

(2) in this season, we should also pay attention to the proper pruning of branches to ensure that jasmine continues to sprout new buds and nurture flower buds, so that the owner of jasmine can enjoy its luxuriant flowers and leaves and enjoy its fragrance in full bloom (7.8.9 months).

(3) watering should be moderate, basin soil should not be watered, jasmine roots should be prevented from waterlogging in cloudy and rainy days, the drainage function of basin bottom should be ensured, the drainage hole of basin bottom should not be blocked when placing flowerpots, and it is appropriate to carry out watering in the morning when watering is needed. It is generally not watered at noon and at night, unless it is watered after missed watering in the morning.

(4) after the new branches grow, they are pruned according to the requirements of the tree shape, cutting off the tips that affect the beauty of the tree shape, transparent tips (branches that are difficult to germinate flower buds), special-shaped tips (single leaves, normally opposite double leaves), and so on.

(5) cut off the flowers in time. The blooming period of jasmine is in the midsummer season, and the bud germinated in this season is bred by the nutrients left in the branches of jasmine after winter. it is usually a single flower, and some are still abnormal buds. If it is not cut off, it will have a great impact on the germination of more new branches and new flower buds of jasmine. When many people see their jasmine, they are very happy to have a bud early for fear that they will lose it and nurture it carefully until it blossoms. As a result, some of them become deformed flowers, while others are not very fragrant even when they are in bloom. The biggest disadvantage is that these flowers absorb a large amount of nutrients in the branches, making it difficult for jasmine to sprout new flower buds when they are in full bloom, because they lose the nutrients to sprout new flower buds prematurely. Pruning off the tip of a Sui Niang flower can at least sprout two new tops, and so on to its full bloom, the new flower buds it germinates are far more than those of these Suiniang flowers which have no "gold content".

[key points of autumn nursing of jasmine]

In autumn, the maintenance of jasmine flowers must pay attention to the following points:

(1) fertilization is strictly prohibited. Avoid growing too many branches to affect the winter.

(2) watering a small amount. Promote the Lignification of jasmine branches to make it through the winter.

(3) keep the branches and leaves. Branches and leaves should not be pruned to make jasmine use them to store nutrients and create conditions for winter.

(4) outdoor maintenance. Jasmine is placed outdoors for maintenance day and night to adapt to the gradually cold seasonal climate to facilitate the winter.

(5) after entering autumn, the new buds growing near the jasmine basin soil, especially on the trunk, generally have to be removed. Whether the new buds germinated on the trunk in spring and summer can be retained or not according to the shape of the tree.

In addition: jasmine leaves yellowing in autumn is not very normal, the main reason is that summer maintenance deviation: such as watering, fertilization, lighting and other improper, only reflected in autumn, if it is better to control in spring and summer, this season is not good radical cure, conservative nursing methods: (1) dry maintenance, timely removal of yellow leaves. (2) with more daylighting, photosynthesis can alleviate leaf yellowing. (3) when adding a small amount of ferrous sulfate (crystal powder) when watering, stop using it as soon as you see some relief in the leaves.

(supplementary)

The main factor of A-jasmine root germination is air temperature. When the temperature is below 30 degrees Celsius, the branches and leaves, branches and roots of jasmine all grow slowly, and flower buds cannot germinate. The cuttings did not sprout new roots, mainly restricted by temperature and light. If the light is strengthened after autumn, there may be a glimmer of hope for cutting branches to sprout new roots.

B-never fertilize jasmine in autumn! Be sure to make the basin soil dry (observe the branches and leaves of jasmine), so that its fibrous roots are plump, the main roots are strong, the branches and leaves are luxuriant, and store enough nutrients to safely survive the cold winter. Note: first, the potted soil is wet and easy to rot (it is obvious that the white fresh fibrous root is the most delicate and most perishable). Second, improper nursing during summer and autumn, if strong stems, branches and leaves can not be retained, jasmine can not use leaves for photosynthesis to maintain life, and there is no strong root system to absorb water to supply leaf formation. Third, improper pruning in late summer and early autumn, only growing branches and leaves were not removed in time because they were too delicate and withered. Fourth, ferrous sulfate solution or other biochemical items cannot be widely used. Improper use can easily lead to the premature death of the whole pot of flowers and trees (jasmine).

[key points of jasmine winter nursing]

Neither dry nor wet (it is easy to dry and spoil the branches without watering, and it is easy to rot the roots if too much watering)

Neither can it be frozen nor wrapped (if it is not bandaged, it is easy to freeze branches, tightly wrapped and easy to lose leaves)

Neither close nor blow (without ventilation, it is easy to close the branches, and too much wind is easy to wither the branches)

Not only afraid of the wind and cold, but also afraid of the sun (without light, it is easy to stuffy branches, too much sunshine is easy to catch cold).

Improper nursing of jasmine in winter has a direct effect on its germination in the following spring. Winter care of jasmine is a key season for jasmine conservation. There are different opinions on how to care for jasmine. Many newspapers, magazines and flower books have been introduced. I have maintained jasmine at home for more than 30 years, especially in winter.

The main points of bandaging branches against cold:

Jasmine also has weak physiological circulation function in winter, such as leaf respiration, root water absorption and so on, but people can not see it as intuitively as in hot weather, and a slight nursing mistake will make it lose its vitality. Therefore, the cold-proof bandage can only use snakeskin bag material, this material can block the wind, cold and breathable. Must not be wrapped with plastic bag materials, plastic bag bandage, although it can temporarily protect against the wind and cold effect, but not breathable directly affect the functional circulation of jasmine, resulting in stuffy branches, branches and leaves, resulting in jasmine branch necrosis, branches and leaves fall, to the next spring but can not sprout slowly withered.
