Why do the leaves of the indoor tangerine fall?

All those who grow tangerines at home, probably at least once in their lives, have encountered the problem that leaves fall off indoor tangerines. Unfortunately, this is not the only disease that can overtake this beautiful tree.

Growing a tangerine tree is possible at home, if you follow the necessary care.

Indoor mandarin is valued by flower growers not only as a fruit-bearing tree, but also as a plant that has an incredible aesthetic effect. It looks very beautiful during the flowering period, its flowers smell very gentle and attractive, and when it is covered with fragrant orange fruits, all eyes are riveted only to it.

Modern scientists-breeders have also bred a dwarf tangerine, especially so that it can be kept not only on the street, but also in a city apartment. Its leaves can, for various reasons, dry out, curl, turn yellow, fall off in a very large quantities. The ovary, which was formed for the further appearance of the fetus, may fall off even before the fruit has time to ripen, and if the fruits do appear, then their color, shape, size, taste change significantly for the worse. In order to prevent this from happening, the owner of the plant, when buying an indoor tangerine, needs to tune in to the fact that the tree will require careful daily care. If a person, due to life circumstances, forgetfulness, laziness or something else, cannot carry out this care, then it is better to leave such a plant in the store.

Since mandarin requires a long daylight hours, it is better to use a phytolamp.

As soon as an indoor tangerine is purchased, care for it will have to begin from the very first day it appears in an apartment or house.

First you have to choose the right place where the tangerine will stand. It is very difficult to do this. This raises another problem. Indoor tangerine loves very much sunlight, and daylight hours which happens in middle lane Russia, he is clearly not enough for normal growth, development and fruiting, so the mandarin will have to provide additional lighting and extend daylight hours so that he feels good and does not get sick. Also, to care for a tangerine, you need competent watering, which will have to be done only on time for the health of the tree. In addition, such a plant, like many others, will have to be fertilized, otherwise it may lead to various diseases.

Causes of the disease

During the dormant period, the foliage curls and falls.

It must be said right away that the leaves of indoor mandarin fall off quite often, and this does not always indicate illness. The most common cause of leaf drop is that the plant has gone dormant. What can be done to stop the leaves from falling off? You need to move the tree to a room where the temperature is cooler, as well as reduce watering and stop fertilizing, and if they do, then in small quantities. This period usually starts late autumn and ends in late winter or in early spring. Those people who have had indoor tangerine in the house for more than a year already know its “habits”, and therefore they already take the tree to a cool place in advance and avoid the fact that too many leaves fall.

Leaves can fall off for the most banal reason that every grower should know about: the plant is just hot, the air in the room is dry. If it is not possible to move the plant to a colder place, then you need to spray the leaves and crown of the plant from a spray bottle daily, and preferably several times a day, in order to create additional air humidification. Next to the pot or tub where the tree sits, you need to put a basin or a bottle of water. Water will evaporate, which will create additional humidity in the air. The soil in the pot must not be allowed to dry out. Usually, such a period when the air is too dry and the plant needs additional care happens in summer and in heating season in winter.

The reason that the leaves fall from the indoor tangerine may be that the plant was transplanted incorrectly. Therefore, it is worth remembering whether a transplant has been carried out recently? What mistakes can be made when transplanting indoor tangerine? First of all, an inexperienced grower can plant a tree too deep into the soil, but this cannot be done. Or perhaps a small plant was placed in a pot too big for it. If the plant has really been recently transplanted and there is a risk that it was done incorrectly, then it must be transplanted again, observing these requirements. And if everything is done right, then the leaves should stop falling.

Very often, “leaf fall” is also caused by the factor that the plant lacks potassium in the soil. In order to replenish it, you need to buy a special fertilizer called potassium nitrate. You need to ask him at the flower shop, carefully study the instructions and make them in a timely manner.

The leaves of an indoor tangerine may turn yellow and fall off, because cold drafts often walk in the room where it stands, or because the plant is flooded, and it does not need so much moisture. In addition, this can happen because the plant is not provided with additional lighting, which is vital for it.

Leaves turn yellow

If the mandarin leaves turn yellow and fall off in large quantities, then you need to think that the plant could be attacked by a spider mite. In order to verify this, you need to take a magnifying glass and look at the leaves of the plant. Most likely, it will be possible to see pests with your own eyes. How to deal with them and how to help the plant?

This does not require a tick to poison special solutions, you only need big piece laundry soap. Before destroying the spider mite, the tangerine must be taken to the bathroom and its crown and leaves should be thoroughly washed under the shower - this procedure alone will wash away the bulk of the pests from the plant. But that is not all.

Next, you need to take a bucket or basin, dilute laundry soap in it so that you get a saturated solution and a lot of foam. You need to take a rag or cotton pad and each leaf of the plant, trying not to miss a single one, you need to wipe soapy water with foam. This will kill the spider mite and its eggs. The next day, the plant should be washed again in the shower and washed off the remnants of soap from it. After a few days, the procedure will have to be repeated. In order to completely destroy the spider mite from your indoor tangerine, three procedures will be enough, and the place where the tangerine stood must be thoroughly washed using the same laundry soap, and the plant should recover.

Mistakes in growing and breeding citrus plants (lemon, tangerine), proper care

Many grow in the room citrus plants, but rarely does anyone succeed in tasting their fruits. Therefore, today we will talk about what mistakes gardeners usually make and how to avoid them.

What are citrus plants afraid of, care errors, biological features of citrus plants

First of all, one must take into account biological features citrus plants. In winter, they need relative rest. From October to February, the temperature in the room should not exceed 12°C. However, this time coincides with the heating season, and high temperatures lead to untimely growth and depletion of plants, which will further affect fruiting.

The critical period is early spring., when warm days suddenly replaced by a sharp cold snap. At the same time, the growth that has begun slows down sharply, the leaves are deformed, and the buds and ovaries crumble. To avoid this, it is recommended to keep the temperature in the room at 14-16°C.

Sometimes in the summer, gardeners take plants to the balcony or even transport them to the country, but it’s better not to do this, since citruses painfully react to any changes and adapt very slowly to new conditions. Dryness and over-hydration earthy coma is also a very common mistake. In the first case, the active roots die off, the leaves curl and fall off along with the flowers and fruits. At excessive watering roots rot, leaves turn yellow.

It is best to pour water into the pan - then the substrate is evenly saturated with moisture and nutrients are not washed out. The most moisture-loving among citrus fruits is lemon, the most drought-resistant is orange. Often plants are watered with very warm water (40°C), which causes the roots to die. You can't go to extremes either. When watering cold water the roots rot, and the plants also die. The water temperature should be 2-3°C, and during fruiting 5-10°C above room temperature.

Remember that the roots of citrus fruits are located in the top layer of the soil, so you have to pry it carefully, and water frequently, but in small doses.

For successful cultivation very important and light mode. Strong shading leads to the formation of large dark green leaves and the exhaustion of plants. Direct sunlight causes a pale color of leaves, burns of fruits and ovaries and their abscission. The most shade-tolerant lemon, the orange is photophilous and heat-resistant.

Citrus love diffused sunlight, it is best to place them on a window facing the southeast or southwest side. And remember: the higher the temperature in the room, the more intense the lighting should be. Great suffering causes dry citrus room air- the tips of the leaves dry up, the buds, ovaries and fruits fall off. To avoid this, regularly wash and spray the plants. If the pot is near the battery, then a container of water is placed on it, which, as it evaporates, will saturate the air with moisture.

Home citrus plants, soil composition, nutrition, top dressing, fertilizers

Highly demanding citrus fruits, especially lemons, to nutrition. It is no coincidence that in the plant kingdom they are called gluttons. feed the plants all year round, except for the period from October to February, when they are given only a weak solution of potassium permanganate to disinfect the soil. The rest of the time top dressing is carried out, alternating organic fertilizers with mineral, once every 7-10 days. This increases the sugar content of the fruit and reduces their bitterness. Recommended fertilizer mixtures: foskamide, darina, ideal, agrovit-cor.

Citrus fruits are highly adaptable to soil conditions. They just cannot stand very acidic soils and the presence of peat. Usually they make up a mixture of turf and leafy soil, humus, sand (2: 1: 1: 1). Citrus fruits should not be placed in the same room with strong-smelling plants, as they do not like other people's smells. They don't like smokers either.: in protest, they can even throw off the leaves.

Responsibility is the transplant. The most common mistakes: transplanting plants with flowers and fruits, which causes them to shed, as well as the destruction of an earthy coma, strong pruning of roots. Both deep and shallow planting can be the reason for the lack of fruit. The root neck should be slightly above the soil level.

Home citrus plants, winter diseases, how to form a crown

Citrus fruits cause the most problems to their owners in winter, when they shed their leaves. There can be many reasons for this phenomenon: light starvation, a combination of insufficient illumination with high temperature and low air humidity; the difference in the temperature of the aerial part and the root system of the plant, when the pot is blown with cold air from the window, and the crown is in favorable room conditions; lack or excess of nutrition. And other problems

Some beginner citrus growers have no idea about the right crown formation. And this is the main reason for the lack of fruiting and the loss of decorativeness.

Without human intervention, the plant will not be able to form a crown in a short time. Thanks to pruning, shoots of the 4th and 5th branching orders develop faster, on which fruits are formed.

At the tangerine the crown is prone to thickening, so frequent thinning is necessary. orange tree rapidly stretches upward, therefore, it is necessary to limit its growth. The lemon has very little branching, so the plant undergoes heavy pruning to get it to flower and bear fruit.

One mature plant in our apartment it can produce up to 30 fruits annually.

Domestic citrus plants, artificial pollination of flowers, fruiting, rejuvenation

Artificial pollination of flowers. When pollinating flowers, pollen is applied with a soft brush) to increase fruit set.

In the rooms you observe a large shedding of ovaries. To avoid this during fruit formation more often water the plants and spray them warm water. Do not forget about the rationing of fruits. The first flowers on young plants must be removed. A three-year-old plant leaves only 2-3 fruits. In by next years they proceed from this ratio: one fruit should be fed from 10-15 leaves, and, of course, the well-being of the plant itself is taken into account so that the first harvest does not turn out to be the last for it.

If the fruiting of a young and healthy tree is weak, then it can be strengthened. For example, drag the main branches with a tourniquet (this technique will cause the accumulation plastic substances and the laying of flower buds); regularly feed the plant with superphosphate. You can grow a seedling and graft it into the crown of a fruit-bearing tree, or graft an eyeball from the top of the plant to its bottom.

If a citrus plant lives with you for a very long time and produces few fruits, it can be rejuvenated. To do this, all large branches are cut into 3-4 eyes, and their branching is cut into a ring. The rejuvenated plant is transplanted into nutrient soil, shortening the roots by one third.

Here, perhaps, is all the wisdom of caring for citrus fruits.

T.Zavyalova, Ph.D. Sciences

Indoor citrus plants require the maintenance of a microclimate similar to natural. If the rules of care are not followed, the trees begin to hurt. It is important to understand why the mandarin leaves fall and take action, otherwise the plant may die.

Physiological features

In late autumn, the mandarin goes into a dormant stage. This period lasts until the end of winter or the beginning of spring. If not provided at this time optimal temperature and correct mode watering, the plant will begin to shed its leaves.

To prevent this problem, the pot with the tree is transferred to a cooler place (temperature + 14-17 ° C). Watering is reduced, because citrus without leaves does not need in large numbers water. Feeding is completely stopped.

Wrong conditions of detention

If it is summer outside and the tangerine sheds its leaves, the reason may be that the habitat is not appropriate for the culture.

Temperature

Under natural conditions, tangerine grows in warm countries, so at home it is worth providing it with a comfortable temperature regime. The indicators should be at the level of + 20-25 ° С. When the culture begins to form buds, the temperature is maintained at about +20 ° C.

Humidity

Mandarin can drop leaves when the air is too dry. This situation is often observed in summer during the heat or in winter during the heating season. For supporting optimal humidity air near the plant, a container with water is installed and sprayed regularly (in the morning or in the evening). You can also increase the humidity with indoor fountain, aquarium or humidifier.

A humidifier installed in the room has a beneficial effect on mandarin

illumination

Lack of light is one of the most common factors for leaf fall. Sometimes the plant does not have enough light after rearranging furniture or during the cold season.

Actions in this case:

• install tangerine tree to a place with high level natural light: balcony, loggia, south or southeast window sill;
• add light with phytolamps or daylight lamps with a short daylight hours.

From direct sun rays protect the plant by shading it. Otherwise, the leaves will get burned, stained, turn yellow and fall off. The root system overheats and does not absorb moisture well, which also affects the condition of the tree.

Wrong care

The leaves of the mandarin turn yellow, and then wither, including due to improper care behind the plant.

Watering

An excess of moisture is evidenced by dry leaves along the edges with a brown crust. The abundance of moisture often provokes rotting of the roots. To check, the plant is carefully removed from the pot along with a clod of earth. If a root system sick, you should transplant the citrus and remove the rotten parts. The soil is changed, drainage is equipped.

If the tangerine has dried up from a lack of water, you can try to reanimate it:

• collect water in a basin room temperature;
• a plant is placed in it so that the liquid is at the level of the edge of the pot;
• watering is done from above until bubbles stop forming in the soil;
• remove, allow excess liquid to drain;
• tangerine tree 2 times a week is treated with the stimulant "Epin" (1 ml per 2 liters of water).

If the tangerine is dried up from a lack of water, the drug "Epin" will help

At home, citrus in the warm season is watered 1-2 times a day. Deviations in one direction or another lead to bad consequences. Between waterings upper layer the soil must dry out.

top dressing

Yellowing and dropping of leaves is often associated with a lack of soil nutrients:

1. Nitrogen - first the lower leaves change color, then the upper ones. To eliminate the problem, nitrogen-containing substances are introduced: ammonium nitrate, ammonium sulfate.
2. Iron - develops a disease called chlorosis. Young leaves turn light yellow, after a while old ones are also affected. To prevent the problem, once a month the culture is treated with iron chelate.
3. Potassium - leaves begin to fall. In this case, potassium nitrate must be added according to the attached instructions.
4. Phosphorus - leaf plates become small and narrow, lose their gloss, tangerine does not bloom. It is good to feed with complex mineral products.

Excess fertilizer is also harmful to mandarin. Purchased drugs for citrus, it must be used strictly according to the instructions, taking into account the phases of plant development. It is important to use boiled and settled water for irrigation, otherwise calcium accumulates in the soil (this is evidenced by white coating on its surface), which prevents the tree from absorbing useful substances.

Watering mandarin should only be settled water

Transfer

If after transplanting the plant began to lose leaves, the process was performed incorrectly. It is necessary to repeat the procedure, taking into account the recommendations:

1. The soil must have a certain composition: turf land (50%), in equal parts leaf earth, humus, sand.
2. Drainage should be laid at the bottom.
3. The pot should match the size of the root system. Growing citrus in a container that is too small or too large will cause leaf drop. The size of the container is increased gradually.

If the root system is damaged, it is washed and treated with heteroauxin or other antiseptic. The plant is placed in a smaller pot with improved drainage.

transplant young healthy tree follows every year. Starting from the age of 7 - 2 times a year. Be sure to transplant after purchase, because store tangerines are planted in peat, in which the supply of nutrients is minimal.

Incorrect reproduction

Inexperienced growers can graft healthy citrus onto trifoliate. Then the plant will definitely shed its leaves, because a deciduous tree was chosen as a stock. Mandarin may even die.

Trifoliata with scion has different biorhythms. In winter, it requires complete rest, while cultivated citrus in room conditions carries out vital processes, although at a slower pace. For vaccination at home, trifoliate is suitable only when the temperature environment lower to + 5-10 ° С.

Pests

To find out the reason why mandarin leaves turn yellow, you should carefully examine the plant for pests:

1. spider mite. You can only see it under a magnifying glass. Recognize the insect by the web that forms on the leaves. The tick sucks the juices out of the plant.
2. Shchitovka. It resembles aphids, but is a great danger to the plant. As a result, lesions on the leaves appear dark spots, and over time, sticky discharge.

To overcome the tick, the plant is placed under warm shower. The remaining pests are neutralized with a soapy solution using a sponge, wiping the stems and leaf blades with it. The next day, the culture is again placed under the shower - in this way soap residue is removed.

For the complete destruction of insects, about 3 treatments are performed with an interval of 2-3 days. You also need to thoroughly wash the place where the flowerpot stands. Against pests, insecticides are used, which are bought in flower shops.

Conclusion

Often tangerine leaves fall under the influence of several factors at once. This fact should be taken into account when diagnosing a disease and choosing a method of dealing with it.

Measures must be taken immediately, because the plant feeds and breathes with the help of leaves. It is worth making sure that the culture is not exposed to drafts, which adversely affect the health of the tree.

When growing mandarin, there may be various problems, for example, drying, curling, yellowing and falling of leaves, shedding of ovaries, chalking and deterioration palatability fruits. Many diseases occur due to a lack of trace elements in the soil, with a lack of light and moisture. That is why you should choose the right location for citrus, if necessary, provide additional illumination, thus increasing daylight hours, timely watering, fertilizing, warm weather take the tree to fresh air.

Mandarin leaves are falling

Quite often, one can observe that leaves fall off a mandarin, but this phenomenon does not always indicate a plant disease. The tree can shed its leaves during the dormant period, which usually lasts from late October to mid-February. In this case, you need to place the tree in a cool room with a temperature of 14-17 ° C and reduce the amount of watering.

Leaves can also fall off when the air is too dry. This can be observed in summer period and during the heating season. In this case, you should spray the crown daily, and place a container of water near the pot, this will help moisten the air near the tree.

The cause of leaf fall can also be an incorrect transplant, when the root collar is buried in the soil, or the citrus is planted in a too large pot. It is necessary to eliminate these shortcomings and observe the plant. If the leaf fall has not stopped, you should look for another reason.

Quite often, mandarin leaf fall causes a lack of potassium in the soil. To make up for it, potassium nitrate is used as a fertilizer.

In addition, the leaves turn yellow and fall off with drafts in the room, excessive soil moisture, and lack of light.

Mandarin leaves turn yellow

Many gardeners are faced with the fact that mandarin leaves turn yellow. Most often, the reason lies in the lack of minerals. So, with a nitrogen deficiency, the lower leaves of citrus first turn yellow and gradually all the rest. To replenish nitrogen in the soil, for example, either ammonium sulfate is used, or. With a lack of iron, the leaf plate acquires a light yellow color, the disease develops chlorosis. Chlorosis first covers young leaves, then spreads to old ones. For prevention this disease Once a month, the plant is treated with iron chelate.

Yellowing of the plate may be due to insufficient lighting or a too cramped pot. The problem can be solved by transferring the plant to a larger pot with fresh nutrient soil.

Why does the tangerine turn yellow

Another reason why a tangerine turns yellow may be an invasion of a spider mite. The pest infects the leaf plate and sucks the juices from the plant, which leads to yellowing and leaf fall. In order to see the spider mite, you should use a magnifying glass. In the presence of this pest, you need to wipe the plant with soapy water.

For its preparation in warm water add a small amount of laundry soap, make thick foam, then, using a cloth or a cotton swab, wipe the leaves and stalks of citrus with foam. Thus, the tick and its oviposition are removed.

Before processing, it is recommended to rinse the wood under the shower. After this procedure, most of the insect will be washed off. The next day after the soap treatment, the remaining soap is washed off in the shower. After 2-3 days, re-treatment is carried out. For the complete destruction of the spider mite, it is necessary to carry out 3 treatments of the tree with soapy water. The place where the affected mandarin stood is thoroughly washed.

Mandarin leaves dry

Sometimes it happens that the mandarin leaves dry, and then crumble. If a dry brown crust has formed on the edges of the leaf plate, the reason is an excess of moisture in the soil. In this case, the tree should be transplanted into fresh, breathable soil with a predominance of leafy soil and good drainage. If during transplantation they are found rotten roots, they must be removed.

Often, citrus leaves dry due to lack of moisture. You can reanimate a diseased plant as follows. Place the pot in a basin of room temperature water so that the water is flush with the rim of the pot. After that, you need to start watering the ground from above. When the soil is completely wet and stops bubbling, drain excess water. Then spray the tree with the preparation "Epin" at the rate of 1 ml per 2 liters of water. Spraying is carried out 2 times a week. This method will allow you to reanimate even a very dried plant.

Many mandarin diseases develop due to improper care and lack of trace elements in the soil. In order to grow a healthy fruit-bearing tree, it is important to keep this tropical crop in its usual conditions, monitor the slightest external changes and take timely measures to eliminate diseases.

In the section on the question Why do room mandarin leaves fall? given by the author I-beam the best answer is Tangerines require careful care. Leaves are shed a little differently, and very often they get sick with spider mites. Inspect the tangerine for pests. Scale insects: brown plaques on the surface of leaves and stems, suck out cell sap. Leaves lose color, dry and fall off. Buds and flowers dry, fruits fall off. Spider mite: appears when the air is too dry - cobwebs appear on the stems in the internodes, the leaves and buds become lethargic and fall off. The fruits fall off.
Tangerines are demanding of light and heat. In winter, mandarin is recommended to be kept in a bright, cold room (up to 12 ° C). Mandarin needs bright diffused light. It grows well near the east and west windows, as well as on the north window. In summer it should be shaded from direct sun.
Watering. In summer and spring, it is plentiful 1-2 times a day with warm water, in winter watering is rare and moderate - 1-2 times a week and also with warm water. However, even in winter it is impossible to allow the earthen clod to dry out, as this leads to twisting of the leaves and falling off not only the leaves, but also the fruits. On the other hand, we must not forget that plants die from excess moisture. Starting in October, watering is reduced.
Tangerines need to be sprayed often in the summer and especially during the heating season.
Soil for young tangerines: 2 parts of turf, 1 part of leafy soil, 1 part of humus from cow dung and 1 part sand.
Soil for adult tangerines: 3 parts sod, 1 part leaf, 1 part cow dung humus, 1 part sand and a small amount of oily clay.

Answer from Natalia A.[newbie]
I am writing, maybe it will be useful to someone. The leaves of the mandarin began to fall off, at first I did not understand what was the matter, then I accidentally noticed many small insects of a transparent brown-ashy color in the ground. They just swarmed on the surface, I suspect that underground too.
I bought "Thunder", sprinkled it, carefully covering the surface of the pot with paper. The insects disappeared, but the tangerine still continued to fall off and dry up.
Transplanted to new land. The fall stopped, and then started again - I think that the pests multiplied in the soil in the roots. Once again I bought "Thunder", but this time I fell asleep deep into it. Did not help.
Then I asked for advice from one saleswoman in a flower shop, she advised me to lay the entire surface of the earth toilet paper and how to spill everything with a solution of potassium permanganate.
I did so. She kept the earth closed for a long time with this paper. Then she took it off and spilled potassium permanganate again.
The pests were defeated.
