When growing tangerines, various problems may arise, for example, drying, curling, yellowing and falling of leaves, shedding of ovaries, shrinking and deterioration taste qualities fruits Many diseases arise due to a lack of microelements in the soil, with a lack of light and moisture. That is why you should choose the right location for the citrus tree, provide additional lighting if necessary, thus increasing daylight hours, water it in a timely manner, apply fertilizer, and take the tree out into the fresh air in warm weather.
Mandarin leaves are falling
Quite often you can observe that tangerine leaves fall off, 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 number of waterings.
Leaves may also fall if the air is too dry. This can be observed in the summer 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 humidify the air near the tree.
The cause of leaf falling can also be improper replanting, when the root collar is buried in the soil, or the citrus is planted in a pot that is too large. 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, the fall of tangerine leaves causes a lack of potassium in the soil. To replenish it, potassium nitrate is used as a fertilizer.
In addition, the leaves turn yellow and fall off when there are drafts in the room, excessive soil moisture, or lack of light.
Mandarin leaves are turning yellow
Many gardeners are faced with the fact that tangerine leaves turn yellow. Most often, the reason lies in a lack of minerals. So, with a nitrogen deficiency, first the lower leaves of the citrus tree turn yellow and gradually all the others. To replenish nitrogen in the soil, for example, either ammonium sulfate or. With a lack of iron, the leaf blade becomes light yellow in color, and the disease chlorosis develops. Chlorosis first affects young leaves, then spreads to old ones. For prevention of this disease Once a month, the plant is treated with iron chelate.
Yellowing of the plate can be caused by insufficient lighting or a too cramped pot. The problem can be solved by transferring the plant to a larger pot with fresh, nutritious soil.
Why does a tangerine turn yellow?
Another reason why a tangerine turns yellow may be an invasion spider mite. The pest attacks the leaf blade and sucks the juices from the plant, which leads to yellowing and falling of the leaves. To see spider mites, you should use a magnifying glass. If this pest is present, you need to wipe the plant soap solution.
To prepare it, add a small amount to warm water. laundry soap, make a thick foam, then use a cloth or cotton swab to wipe the leaves and stems of the citrus with the foam. This removes the tick and its oviposition.
Before processing, it is recommended to rinse the wood in the shower. After this procedure it will be washed off most of insect. The next day after soap treatment, the remaining soap is washed off in the shower. After 2-3 days, re-treatment is carried out. To completely destroy spider mites, it is necessary to carry out 3 treatments of the tree with a soap solution. The place where the affected tangerine stood is thoroughly washed.
Mandarin leaves are drying up
Sometimes it happens that tangerine leaves dry out and then fall off. If a dry brown crust has formed on the edges of the leaf blade, the reason is excess moisture in the soil. In this case, the tree should be replanted in fresh, breathable soil with a predominance of leaf soil and good drainage. If rotten roots are found during transplantation, they must be removed.
Often citrus leaves dry out due to lack of moisture. You can revive a sick plant as follows. Place the pot in a bowl of water room temperature so that the water is flush with the edge of the pot. After this, you need to start watering the soil from above. When the soil is completely wet and stops bubbling, drain off the excess water. Then spray the tree with 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 revive even a very dried out plant.
Many tangerine diseases develop due to improper care and lack of microelements in the soil. To grow a healthy fruit-bearing tree, it is important to keep this tropical crop in its usual conditions and monitor the slightest external changes and take timely measures to eliminate diseases.
Mandarin leaves turn yellow and fall off for several reasons. This is the result of improper care; the plant may go into retirement or be affected by disease. To effectively eliminate the problem, correct diagnosis is necessary, which can only be carried out experienced flower growers. So, why do tangerine leaves turn yellow and fall off? Treatment from specialists detailed photo. Optimal conditions growing a plant.
Why do tangerine leaves fall off? Treatment of the disease
Tangerine leaves often fall off in late autumn. Why? In the period from the end of October to the beginning of February, in indoor conditions, the plant begins a dormant period. This is caused by shortening daylight hours.
Although citrus fruits do not naturally defoliate during the winter, when home growing a period of rest is simply necessary. Without winter rest it may die mature plant, whose age exceeds 3-4 years. What to do? If the tangerine leaves fall in the fall, it is transferred to a cool room where the air temperature does not exceed +18 degrees. Here additional lighting is organized using fluorescent lamp at 20-40 watts, it will provide 12 hours of daylight. Watering is reduced, since a plant without leaves consumes little moisture. Fertilizers are not applied to the soil until the period of intensive growth begins (late February - early March).
If it's summer outside, then why do the tangerine leaves fall? Leaf fall is often a reaction to unfavorable growing conditions. Often this is the result of waterlogging or dryness of the soil, perhaps these two factors alternate. For tangerine, regular watering with uniform moistening of the earthen clod is important. In summer, it is watered 2 times a week after the top layer of soil has dried. In winter, watering is reduced significantly, as citrus fruits go into retirement. When over-watered and over-dried, the root system suffers. That is why in both cases it is necessary to place the tangerine in a greenhouse. This plastic bag, which does not touch the leaves of the flower. Watering under the greenhouse is reduced and sprayed more. Epine is added to the water for spraying, and for watering - root once a week. There should be moist air under the greenhouse. It is ventilated every day for 15 minutes. The greenhouse can be removed for a longer period of time, thus accustoming the flower to indoor conditions, if the leaves no longer fall off and new ones appear.
Leaves fall off if indoor tangerine was transplanted incorrectly. In this case, we are talking about violating the integrity of the earthen coma around the roots. It is correct if the tangerine is transferred into a pot, the diameter of which is 1-2 cm larger than the previous one, without violating the integrity of the earthen lump. If still homemade tangerine replanted and its leaves fall off 1-2 weeks after replanting, it is necessary to place the flower under a greenhouse (how to do it is described in the previous paragraph), reduce watering (in order to reduce the load on the root system), and pay more attention to spraying.
The tangerine sheds its leaves if the pot size has been greatly increased as a result of replanting.. Here we are talking about waterlogging the susstratum in the pot. The root system of the plant has not yet occupied the entire volume of soil provided to it. An excess of moisture will accumulate here, which leads to rotting of the roots. In this case, watering should be reduced, wait until the soil dries, and then water moderately; you need to add root to the water once a week. Regular spraying with epin will not hurt, do not fertilize, provide the flower with proper lighting, in winter it should be illuminated with a fluorescent lamp.
If a tangerine has lost all its leaves, can it be saved? In this case, you need to find out whether its root system has rotted or dried out. To do this, the plant is carefully removed from the pot, without disturbing the integrity of the earthen ball, and the roots are examined. They should be elastic and have a light cut. Otherwise, the flower cannot be helped. Next, the plant is returned to the pot and placed under a greenhouse. You cannot water it without leaves. The soil can be kept slightly moist, but it should be dry on top. Next, the plant is placed under a greenhouse and sprayed, be sure to use Epin.
Why do tangerine leaves turn yellow? How to treat the disease?
Mandarin leaves turn yellow if it stands under straight lines. sun rays without shading. In this case, not only the crown of the flower suffers, but also its root system.
Leaves get burned in direct sunlight. In this case, the tangerine leaves become stained, turn yellow and fall off. The root system overheats under the sun and therefore does not absorb moisture well. This affects the crown. It turns yellow again and falls off. You should also not spray the flower in hot weather. It is better to do this either in the morning or late in the evening. If the room where the tangerine grows is very hot in the summer, then they organize it in the room good ventilation air and definitely shade the flower. In winter, tangerines cannot be grown at high temperature. This depletes the plant and it needs a period of rest. So, if a flower turns yellow, then it must be shaded, the earth clod is not allowed to overheat, and it is watered so that it has time to dry out. upper layer soil. Here you can use root. Spraying is required, epin is added here.
The leaves of indoor mandarin turn yellow if it lacks microelements. In this case we are talking about chlorosis. Lemon leaves turn yellow, but the veins on them remain green. The flower can be cured by regular feeding, which contains microelements such as iron, zinc, sulfur, manganese and magnesium.
If there is a lack of phosphorus in the soil, young leaves of tangerines may turn yellow. They lose their gloss and develop narrow and long. In such conditions, tangerine does not bloom. What to do? It is necessary to feed the plant regularly complex fertilizers. Important!!! Mandarins can only be watered with boiled, settled water. Otherwise, calcium accumulates in the soil (looks like white plaque on the top layer of soil). It prevents the roots from absorbing nutrients.
There are many resources on the Internet dedicated to citrus fruits. Studying the most popular of them, I constantly come across newbies who are trying to find the answer to the same question: " Why are my lemon leaves turning yellow and falling off?". To each such question, I answer that most of the problems of citrus fruits are associated with the root system. If the loss of foliage becomes widespread, it is necessary to check the root system. I have already described all this in the topic "", but today I want to touch on this topic again and describe everything in more detail, especially since we had to save a seemingly healthy plant again.
Background of leaf fall
A few months ago I was happy with the acquisition of an adult and very beautiful citrus -. It came with ripe fruit, which I picked for tasting. At that moment I was very alarmed by the wet “heavy” soil, which seemed to have been taken right next to the store. However, after several days of acclimatization, he not only did not show any discomfort, but also gave a good increase in . The flowers successfully set fruit and the plant as a whole made me very happy.
The only sad thing was that along with the plant in this store I also acquired a formidable pest -. After discovery, the tree was immediately moved to a new location so as not to endanger the entire collection. And then the problems began: 1-2 leaves flew off per day, which looked healthy, and only upon careful examination was a slightly yellowed vein visible. There was no massive leaf fall, but the leaves gradually fell over the course of several weeks. I associated all this with a change in living conditions and a pest. But when I stopped noticing the scale insect for a long time and acclimatization was about to be completed, I began to worry, but could not guess what was the reason for the falling leaves on the citrus tree.
Detecting the Problem
At the store, Chinotto was put in an ugly black bucket. Today I decided to buy a normal one white pot and reload, replacing part of the soil if necessary and at the same time inspecting the roots. What could be assumed by looking at the plant that has produced young shoots and set fruit: |
But, having taken the tree out of the pot, I began to be horrified: the earthen ball was not braided, and the roots that were adjacent to the walls were rotten:
Taken measures
I realized that the matter would definitely not end with a simple transshipment. I had to free the roots from bad soil, but in the center there was an incomprehensible mixture, similar to fossilized clay with sand, which could not be gotten rid of so easily:
The picture is scary, isn't it? I still don’t understand how, with such a state of the root system, the tree not only did not die, but also tried to produce growth and bear fruit.
To remove the fossilized clay, I had to soak the roots in water for half an hour, adding four caps of the Rooter preparation (manufactured by Gileya). I don’t have anything else, but at least it didn’t interfere with such a kumquat resuscitation.
While the soil was soaking, I prepared a light soil mixture consisting of leaf humus and chernozem in a ratio of approximately 4:1:
My son gave me a store-bought tangerine with small fruits. But now the flowers and leaves are falling off and there is no ovary. How to care for a tangerine? Is it possible to eat its fruits?
Galina Kuleshova, Gomel region.
Tangerines, oranges and all indoor citrus fruits - whimsical plants. It is necessary to create appropriate conditions for them. The air temperature in winter should not be higher than +15 degrees, humidity - more than 70%.
In winter, it is difficult to maintain such conditions in apartments. That's why citrus fruits shed flowers, ovaries, and then leaves first. With store-bought plants too more problems. They have come a long way from where they were grown to your home. This is a stressful situation for them. In addition, peat, in which purchased plants are usually planted, is not intended for long-term cultivation of not only citrus fruits, but also other indoor flowers - the amount and set of nutrients in it are minimal.
Measures to save tangerine
Urgently replant the tangerine in good nutrient soil. The composition is approximately this: 1-2 parts turf soil, 1 part humus soil, 1 part sand. You can also take special soil for citrus fruits.
The pot for the tree must match the volume of the root system. Citrus fruits do not like overly large dishes. It is advisable to transplant them into a large container, gradually increasing the size of the pot.
During active growth(for tangerines this is March-April) and in the summer (in August) feed with complex mineral and organic fertilizers once every 2 weeks. The rest of the time - less often.
Water moderately, avoiding stagnation of water in the pan, and only after the top layer of soil has dried. Spray frequently. Avoid drafts and cold air.
Watch for pests (premature leaf fall can also cause severe mite damage).
Is it possible to eat fruits from indoor tangerines?
I wouldn't recommend it. They are unlikely to be useful, since they were grown using large quantity pesticides during treatments against pests and diseases and have accumulated a lot harmful substances. Miniature tangerine trees are kept more for beauty.
Champagne, Olivier, tangerines - the invariable trio at the New Year's celebrations in our country. It's funny that all these components came to us from abroad. Champagne was invented in France, and Maitre Olivier, the author of the famous salad, is of French origin, and tangerines, as you know, grow in hot countries.
OWN AMONGST STRANGERS
Nevertheless, foreign dishes have fully adapted to local conditions. Crimean winemakers have mastered the production of champagne. The housewives replaced the quail and capers in the salad with chicken and pickles. And delicate citrus fruits began to be grown in the northernmost subtropics of the world, on the Black Sea coast of the Caucasus and in the subtropical zone of the Krasnodar Territory.
Attempts to grow citrus fruits in Georgia began in the Middle Ages. By historical information, in the 17th century, lemons and oranges grew in the Batumi region. The first industrial plantations were founded in the middle of the 19th century under the patronage of Prince M.S. Vorontsov, the Tsar's governor in the Caucasus. During the same period, scientific centers for the acclimatization of subtropical crops were founded: the Sukhumi Botanical Garden, the Kutaisi and Gagra nurseries, and a little later the Nikitsky Botanical Garden in Crimea.
Gradually, an assortment of citrus fruits was selected that could grow and produce stable yields in local conditions. By the middle of the 20th century, it was Abkhaz tangerines that decorated New Year's tables in the USSR Unfortunately, with the collapse of the Soviet Union, citrus plantations went into decline. The situation was aggravated somewhat harsh winters. Therefore, now we mainly eat tangerines from Morocco, Turkey, and Israel.
TANTARINE OR SOMETHING ELSE?
In fact, the name “mandarin” is more of a trade name than a botanical definition. Any small citrus fruit with orange, yellow or greenish peel is sold in trade under the name tangerines. Their shape can be round, flattened, with an elongated nose. Some varieties have no seeds, others have many seeds.
Strictly speaking, real tangerines grow in India and Indochina; they have small, highly flattened fruits that do not tolerate transportation well. When grown in other countries, tangerines were crossed with local forms of citrus fruits, trying to increase resistance to natural conditions and consumer qualities.
Tangerine, mineola, capamondia, clementine, limandrine, kinnow, rangpur-this is not a complete list citrus hybrids based on tangerine.
In our country, they grow a frost-resistant form of tangerine - unshiu (or unshu). This plant is characterized by short growth and early ripening. On its basis, varieties zoned for Georgia, Adygea and the Krasnodar Territory were bred: Pioneer 80, Sochinsky 23, Kavano-Vase, Iberia, Michurinets,
Amateur gardeners are trying to grow tangerines even north of the subtropics. With some effort, grow tangerines in open ground it is possible even in the Donetsk, Rostov and Astrakhan regions.
Dwarf tangerines of the Unshiu group are chosen for cultivation, and to increase winter hardiness they are grafted onto wild lemon Pontsirus trifoliate. It is a deciduous plant and goes dormant during the winter. At the same time, the evergreen scion also slows down physiological processes and tolerates winter more easily. The main tasks in these places are to protect evergreen plants from winter frosts and provide a long growing season for fruit ripening and wood formation.
Back in the mid-70s, scientists developed many agricultural techniques. For example, as winter shelter a film is used with a nylon film thrown over top fishing net. These materials rub against each other under the influence of the wind, and an electrostatic field arises that retains the heat of the earth. Under such a strange roof in winter the temperature is 5-8" higher than outside.
Another method that has become more widespread is growing in trenches. For planting, pit-trenches are prepared 1 m wide and about 1.5 m deep. The walls are strengthened against collapse, and supports for shelter are installed on top. It turns out something like a dugout greenhouse. Fertile soil is placed at the bottom and seedlings are planted in such a way that the crowns of adult plants do not rise above ground level. In autumn, as cold weather sets in, a film is first stretched on top, and then the wooden boards with windows. The ends are first left open and then closed. Before complete cover, rotting manure is thrown into the trench and the plantings are watered abundantly. In the spring, as the weather warms, the shelter is gradually removed.

Indoor tangerine leaves are falling: causes and treatment
During the dormant period, leaves curl and fall.
It must be said right away that the leaves of indoor tangerines fall off quite often, and this does not always indicate disease. The most common reason for leaf drop is that the plant has gone dormant. What can I do to stop the leaves from falling? You need to move the tree to a room where the temperature is cooler, and also reduce watering and stop applying fertilizers, and if you apply them, then in small quantities. This period usually begins late autumn and ends in late winter or in early spring. Those people who have had an indoor tangerine in their house for many years already know its “habits”, and therefore take the tree to a cool place in advance and avoid the fact that too many leaves fall off.
Leaves can fall for the most banal reason that every gardener should know about: the plant is simply 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 sprayer daily, or better yet several times a day, in order to create additional air humidification. Next to the pot or tub where the tree sits, you need to place a basin or bottle of water. The water will evaporate, which will create additional humidity in the air. The soil in the pot should not be allowed to dry out. Typically, the period when the air is too dry and the plant requires additional care occurs in the summer and during the heating season in winter.
Mandarin diseases: why do mandarin leaves turn yellow, dry or fall off?
Another reason why a tangerine turns yellow may be an invasion of spider mites. The pest attacks the leaf blade and sucks the juices from the plant, which leads to yellowing and falling of the leaves. To see spider mites, you should use a magnifying glass. If this pest is present, you need to wipe the plant with a soapy solution.
To prepare it, add a small amount of laundry soap to warm water, make a thick foam, then use a cloth or cotton swab to wipe the leaves and stems of the citrus with the foam. This removes the tick and its oviposition.
Before processing, it is recommended to rinse the wood in the shower. After this procedure, most of the insect will be washed away. The next day after soap treatment, the remaining soap is washed off in the shower. After 2-3 days, re-treatment is carried out. To completely destroy spider mites, it is necessary to carry out 3 treatments of the tree with a soap solution. The place where the affected tangerine stood is thoroughly washed.
Mandarin leaves are drying up
Sometimes it happens that tangerine leaves dry out and then fall off. If a dry brown crust has formed on the edges of the leaf blade, the reason is excess moisture in the soil. In this case, the tree should be replanted in fresh, breathable soil with a predominance of leaf soil and good drainage. If rotten roots are found during transplantation, they must be removed.
Often citrus leaves dry out due to lack of moisture. You can revive a sick plant as follows. Place the pot in a bowl of water at room temperature so that the water is flush with the edge of the pot. After this, you need to start watering the soil from above. When the soil is completely wet and stops bubbling, drain off the excess water. Then spray the tree with 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 revive even a very dried out plant.
Many tangerine diseases develop due to improper care and lack of microelements in the soil. To grow a healthy fruit-bearing tree, it is important to maintain this tropical crop in its usual conditions, monitor the slightest external changes and take timely measures to eliminate diseases.
Mandarin leaves and fruit fall off why
Citrus fruits, when changing conditions, often react to this by dropping leaves and fruits, after adaptation and when proper care it stops. Analyze the tangerine's conditions to detect possible errors in care. Mandarin is light-loving, but requires shading from the hot midday sun. Water tangerines throughout the year regularly, but moderately, allowing the top layer of soil to dry slightly before the next watering. Excessive watering leads to acidification of the soil (especially with poor drainage) and death of roots, and lack of moisture leads to curling and falling leaves. Mandarin does not like drafts, so when taken out into the fresh air in the summer, it is placed in a place protected from the wind. If there is no opportunity to give the plant a “vacation in the garden”, then the tangerine standing in the room is provided constant influx fresh air, regularly spray the crown with water at room temperature.
Do not fertilize the plant until the leaf fall stops. To maintain immunity, carry out a cycle of spraying the tree with bioregulatory growth preparations (Epin, Epin-extra, Zircon).

Mandarin care rules, growing problems, pests and measures to combat them, as well as useful healing properties
Rutaceae family. The most famous is the Unshiu (seedless) mandarin. The plants have corrugated, leathery leaves. Unshiu mandarin does not have a clearly defined dormant period. The leaves that fall off throughout the year are replaced by newly formed leaves. Mandarins are propagated by grafting and air layering, very rarely by seeds, since its fruits have almost none.
Mandarin is a perennial woody Evergreen , reaching a height of 1 m in indoor conditions, with a well-leafed compact crown. The leaves are dark green, leathery, lanceolate. Flowers with a delicate wonderful aroma, white, appear in the spring. Tangerines ripen by autumn and can hang on the plant for several months. On one tangerine tree can grow up to 50 - 70 fruits.
Rules of care behind the plant:
Temperature: Tangerines are demanding of light and warmth. Budding, flowering and fruit set best occur at average air and soil temperatures of + 15-18°C.
Lighting: Bright diffused light. It will be good near the east and west windows, as well as on the north window. Shading from direct sun is needed in spring and summer during the hottest hours.
Watering: In summer and spring, generously 1-2 times a day warm water, in winter, watering is rare and moderate - 1-2 times a week and also with warm water. However, even in winter, the earthen clod should not be allowed to dry out, as this leads to curling of the leaves and falling of 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.
Air humidity: Tangerines are regularly sprayed in the summer, but if they are kept indoors in winter central heating, then they spray it in winter. When kept in a room with dry air, oranges are susceptible to attack by pests (mites and scale insects).
Transfer: Young trees must be replanted annually. Transplantation should not be carried out if the roots of the plant have not yet entwined the earthen ball. In this case, it is enough to change the drainage and top layers of soil in the pot. Fruit-bearing trees are replanted no more than once every 2-3 years. Replant before growth begins. It is not recommended to replant the plants after growth has finished. When transplanting, do not greatly destroy the earthen ball. Good drainage must be ensured. The root collar in the new container should be at the same level as it was in old dishes. It is not recommended to replant tangerine trees with flowers or fruits, as this leads to the fall of both. Young plants need light soil, and larger ones need heavier soil. The acidity of the soil for citrus fruits should be pH = 6.5-7.
The soil for young tangerines: 2 parts turf, 1 part leaf soil, 1 part humus from cow manure and 1 part sand.
Soil for adult tangerines: 3 parts turf, 1 part leaf, 1 part cow manure humus, 1 part sand and a small amount of fatty clay.
Fertilizer tangerines: In the first half of summer, fertilizing watering is used. It increases the sugar content of the fruit and reduces the bitter taste that is characteristic of citrus fruits when grown indoors.
