Brown spots on lemon fruits. What you need to know about growing lemons at home

Diseases homemade lemon can cause a lot of trouble, and sometimes even lead to the death of the plant if the problem is not treated in a timely manner.

Need to know possible diseases indoor lemon to prevent his death

Causes

Lemon diseases can be caused by a number of reasons:

1. Weakened immunity, which is caused by improper care.
2. Poor quality, unsuitable soil can become fertile ground for the appearance of pests.
3. Infection of a houseplant from the street - if you take flowerpots outside in the summer.
4. Insects that spread various infections.
5. Diseases already suffered by the plant can cause new ailments.

Symptoms of diseases

Some of the common diseases of homemade lemons are aphids and scale insects.

The first affects the leaves of the plant or penetrates the soil. Aphids can be transmitted by other plants near the lemon. You can bring it into the house yourself with a bouquet of wildflowers. The scale insects end up on lemon leaves as larvae. The adult is already motionless. It sticks to the stem of the plant or the veins on the leaves.

A common pest among citrus fruits is the spider mite. It can destroy all the green leaves and cause the lemon to die. Such diseases affect the leaves if the tree is young, weakened, or if there are special lemon pests that affect only it.

The fight against them can be lengthy, but quite successful if the correct chemical or homemade preparation is selected for the indoor lemon. They can also be used for preventive purposes.

In most cases, lemon diseases are associated with a violation of recommended care. This plant requires increased attention. To avoid leaf disease, you need to ensure a stable temperature, sufficient lighting and rational watering.

By maintaining a balance between these three factors, you can prevent a large number of cosmetic defects of the plant that are not a serious disease, but spoil the appearance.

1. Yellowed and fallen leaves.
2. Lack of fruiting.
3. Discarding the formed ovary.
4. Drying of branches in winter.

Bacterial diseases are much more difficult to treat. It is recommended to entrust the work to specialists who will help your plant quickly cope with the disease.

Illnesses not related to care

Experts distinguish diseases that are inherent in citrus plant varieties. Among them you can find those that are very difficult to eliminate on your own.

It is advisable to have a direct consultation with a specialist who can clearly look at the affected lemon and recommend a suitable drug, which may be Bordeaux mixture, phytosporin, hydrogen peroxide (substances containing alcohol are prohibited), copper sulfate as a fungicide and other drugs.

Lemon diseases:

1. The leaves are unevenly pigmented in spots - a leaf mosaic. Not to be confused with chlorosis, in which the edges of the light spots are fuzzy.
2. Brown or yellow spots, with hardened plaques inside, quickly affecting the entire plant - bacterial canker of citrus fruits.
3. Two species of aphids are known pests of lemons. The basal aphid differs from the ordinary green aphid, which is difficult to confuse with other insects, in its white color and habitat - in the ground.
4. Gradual death of the tree, the leaves are the first to be affected, first they dry, then the entire branch, and the fruits become covered with red-brown generalized spots - “Anthracosis”.

Prevent lemon diseases at home such as tristeza, root rot and melseko is possible if you provide the tree with it from the very beginning stable place and diffused, bright sunlight.

If the leaves begin to turn yellow, first of all you need to remember when the last watering was, measure the temperature in the room, remove drafts (many tropical and subtropical plants they cannot be tolerated) and consult a specialist if you do not have sufficient experience in recognizing the problem.

Lemon trees (Citrus Limon) decorate houses and apartments and delight many gardeners in winter time when the weather outside is not conducive to gardening. Indoor lemon Tree is small decorative tree, which is known not only for its orange-yellow fruit, but also for its small size and shiny green foliage.

This popular variety For home grown lemons in Ukraine, as well as the Meyer variety. Its fruit is less acidic than most lemons, making it a favorite for cooking. This variety is least susceptible to various diseases and is adapted to dry air in rooms and apartments in winter.

As houseplants, they are second to none in beauty, but sometimes they run into a little trouble, so when you notice yellow spots or hard spots appearing yellow leaves, your lemon tree is likely only having minor problems with a simple solution.

Yellow spots and dots on lemon leaves may be caused by problems environment, insects or diseases. Let's take a closer look at the causes of yellow spots on lemon leaves.

Damage by insects

Yellow spots on leaves may be the result of sucking insects that feed on leaf juices. Spider mites leave yellow dots, like grains, on leaves and are often difficult to notice right away. Scales look something like hollow scales, and often merge with the bark. They also suck juices from leaves and fruits, leaving yellow spots. You can get rid of them using insecticidal soap and bedbug traps. Before using the insecticide, carefully read the instructions.

• Shchitovka

How to get rid of scale insects on a lemon tree

It is quite possible to defeat the scale insect. To begin with, you need to wash all the leaves, on both sides, the trunk and branches of the lemon tree with diluted liquid or insecticidal soap or dishwashing detergent. Then use an available safe insecticide, for example, Aktara or Fitoverm, in accordance with the instructions. Carefully process the leaves, trunk and branches on all sides. A small amount of mineral oil can be used to stop the movement of these sedentary insects, but it should be applied with caution and only when the ambient temperature is no higher than 27 degrees Celsius.

• Ticks

Some various types The mites feed on the leaves of the lemon tree, leaving small yellow spots called stippling and subsequently causing the leaf itself to turn yellow. Citrus red mite (Panonychus citri), spider mite (common spider mite), and Yuma spider mite (Eotetranychus yumensis) are the most common ones found on lemons. You may find tiny silky webs where they feed, on the undersides of leaves. Using a magnifying glass can help you get a clearer picture of the mites your plant has been exposed to.

How to get rid of mites on a lemon tree

Ticks are not insects, so broad-spectrum insecticides do not work on them. In addition, broad-spectrum insecticides often make matters worse by killing natural enemies that may inhibit mite proliferation. Sprays with sulfur or mineral oil are often effective against mites and are considered safe for food crops.

Damage from diseases

Diseases to which lemon trees are susceptible are usually bacterial or fungal in nature. Citrus canker is a highly contagious bacterial plant disease that causes circular yellow spots on leaves, fruit and branches. Fungal disease such as citrus peel often begins as yellow spots that quickly develop into scabs. Oily stains, another fungal disease that causes yellow and brown spots. To treat and prevent these infections, a copper-based fungicide is used.

• Root rot (phytophthora)

Although store-bought soil in pots with lemons is often already sterile, this type of disease is also common due to the use of homemade soil mixtures in indoor gardening. This soil fungus affects root system susceptible varieties, destroying feeding roots. Affected trees may develop yellow leaves or drop leaves, depending on the severity of the root damage.

For this purpose, it is recommended to transplant the lemon tree into new soil and trim off all damaged roots. Water with a small amount of fertilizer daily or weekly to help the plant replenish nutrients due to the loss of some roots.

Flaw nutrients

Irregular yellow spots on leaves that do not have clearly defined edges may indicate a nutrient deficiency. Magnesium deficiency causes yellow spots on the outer edges of leaves and is most common, especially when soil pH drops below 5.0. The acidity of the soil can be increased by adding lime or peat to the soil until the pH reaches between 6.0 and 8.0. This will allow the roots to access the magnesium in the soil. Zinc deficiency also results in yellow spots between leaf veins and can be corrected by spraying the leaves with zinc sulfate.

Cold Damage

Since most lemon trees are not cold-hardy, damage from cold temperatures can result in yellow spots on the leaves. Fruit may also develop spots due to cold damage.

Diseases and ailments of indoors citrus plants: symptoms and photos

In this article, we will help you, using photos and descriptions of the main symptoms of ailments, recognize diseases of citrus plants.

Black carbon deposit

Symptoms: Black charcoal mold spreads on leaves or fruit. It develops due to the nectar deposits of sucking insects such as aphids, mealybugs, scale insects and whiteflies.

Most effective way Prevention of this disease is the fight against these insects. To control the reproduction of insects and prevent them from secreting secretions, use any available insecticide that can be purchased at a gardening store. When spraying on a tree, make sure that the top and bottom sides of the leaves are treated equally. A second spraying may be required after 10 to 14 days, depending on the severity of insect pest damage to the plant.

To eliminate mold that has already formed, you need to spray the crown with a fungicide based on liquid copper. It is quite effective to use copper sulfate to control charcoal mold, but if leaf damage is widespread, a second spray after 14 days is required.

Damage from growth regulator

Symptoms: Leaves curl up like a bowl or curl, turning yellowish if growth regulators have not been applied correctly. The fruits fall off while still unripe, and the plant looks lethargic.

Shortagenitrogen fertilizers

Symptoms: Leaves turn completely pale green when there is a lack of nitrogen. This is caused by unbalanced fertilizers, unfavorable soil conditions, or unhealthy roots.

Destruction of Mesophyll cells

Symptoms: Soft fabric between the veins of the leaf becomes depressed and transparent or pale green. This occurs due to spraying or watering the plant sufficiently cold water(below +10 degrees Celsius). Affected leaf tissue turns yellow-brown or dies.

Zinc deficiency

Symptoms: Extensive chlorosis develops between the veins when there is a lack of zinc fertilizer. The leaves of the plant become light green, sometimes almost white. Also, with a lack of zinc, a decrease in the size of the leaves, their curvature and ugliness, and shortened internodes are observed.

Manganese deficiency

Symptoms: Leaves become completely yellowish, but larger veins remain slightly green. The symptoms of manganese deficiency are the same as those of zinc deficiency. Both conditions are more common on young leaves that start growing in the fall, when the soil cools and root activity decreases.

Potassium deficiency

Symptoms: Yellowish leaves that are bent downward at the edges, especially at the ends, are symptoms of potassium deficiency.

Magnesium deficiency

Symptoms: yellowing of leaves, starting from the tip and sides, which progresses to inside leaf. A V-shaped dark green spot is observed at the base of the leaf.

Iron-deficiency anemia

Symptoms: Interveinal chlorosis due to iron deficiency appears as yellowing between the small dark green veins. This is often associated with cooling of the soil and a decrease in root activity, and develops on new young leaves.

Sodium toxicity

Symptoms: yellowing, brown leaves, as well as darkening of leaves and their premature falling. High total mineralization or excess sodium or chlorine can cause such leaf damage. In addition, there may be general symptoms throughout the tree, such as stunted growth.

Boron toxicity

Symptoms: Speckling or yellowing, mottling on the undersides of leaves, and premature leaf drop may be due to excess boron; severe symptoms may include dying branches.

Root rot

Root rot, also referred to as brown rot or gommosis, is a tree disease caused by Phytophthora fungi that live in the soil.

Symptoms: yellow and dying leaves, fruits that are too small in size, the trunk has damaged bark with a dark sticky liquid (gum) oozing in the form of a canker. As a result, the bark peels off from the trunk in the form of vertical stripes. Such damage can spread along the trunk in the form of a ring.

Late blight (Phytophthora) can deteriorate the health of the entire tree, stopping its ability to grow, reducing the ability of the roots to absorb water and nutrients, leading to wilting. When the roots are infected, the root surface becomes soft, the color changes and they become watery. Fibrous roots have a peeling surface, leaving only a white thread-like root.

To eliminate root rot and gommosis, it is necessary to: improve soil drainage, use irrigation practices, apply fungicides, pruning affected roots and replanting the tree.

Wonderful garden and orchard, without problems and without the hassle!

Pests and diseases of indoor lemon

Lemon like everyone else houseplants May be periodically affected by diseases and pests.

Common lemon diseases.
Of the diseases that affect homemade lemons, gum disease (gommosis) and sooty fungus are especially dangerous.

Gommoz. When gommosis occurs, cracks appear on the bark, most often at the bottom of the trunk, from which a sticky liquid emerges - gum, the bark gradually dies, as a result of which the tree begins to wither and may die.
Most often, homosis occurs in plants grown from cuttings. Factors contributing to the appearance of the disease: deep planting, prolonged waterlogging of the soil, watering with cold water and excess nitrogen fertilizing.

Gomosis on a lemon trunk

Control measures: First of all, it is necessary to eliminate the causes of homosis. Wounds that appear on the bark are thoroughly cleaned, disinfected with a 3% solution of copper sulfate and covered with a paste of copper sulfate and lime. You can also use garden pitch or clay for smearing.

Sooty fungus on lemon leaves

Sooty fungus. A dark coating appears on the leaves, and as the disease develops, on the branches and trunk. This is sooty fungus; it settles on the secretions of sucking insects, such as scale insects and scale insects. Sooty fungus interferes with the normal growth and development of plants.

Control measures: fungus from leaves, remove wet cloth, and from the branches and trunk - cleaned with brushes. In addition to such removal, trunks and branches covered with sooty fungus should be washed with lime, and the room where the diseased plant is located should be thoroughly ventilated.

Pests

Scale insect on a lemon trunk

Shchitovka
Scale insects are one of the most common lemon pests and most often settle on weakened plants. These are small insects; they can move only in the larval state. Adult pests attach themselves to the leaf veins from below and persist for quite a long time. When they live on a plant for a long time, scale insects reproduce well and also infect the upper side of leaves and even young shoots. Plants that are severely damaged by the pest become depleted and dry out.

Mealybug
Scale insects, insects similar to scale insects, but larger and more mobile, cause damage in the same way as scale insects.

Aphid
It settles in colonies on flowers, ovaries, shoots and on the underside of foliage. It feeds on sap, which causes the foliage to curl and dry out. Insects whose length is 1.2-2.1 millimeters are colored dark green.

Control measures:
Lemon leaves are washed from scale insects, scale insects and aphids with soapy water or tobacco infusion using a toothbrush. For 1 liter of water you need to take 50-60 g of tobacco and leave for two days. Washing should be repeated several times. A solution of green soap with anabasine sulfate gives good results. In a liter of water you need to dissolve 4-5 g of green soap and add 1.5-2 g of anabasine sulfate. The affected plants are washed or sprayed with this solution. After a day, the solution should be washed off; for this, the plants are washed with clean warm water. This spraying is repeated 3 times every 7 days. You can also use the following solutions:

NIUIF-100 (thiophos) - 10 g per 10 l of water; spraying with thiophos can be combined with treatment with Bordeaux mixture or superphosphate extract;

Chlorophos - from 30 to 100 g per 10 liters of water (after checking for burns);

Scale insects on lemon leaves

Preparation BI-58 or Rogor - 10 g per 10 liters of water;

Anabasine sulfate - 30 g per 10 liters of water plus 40 g of green or laundry soap;

Karbofos - 30 g per 10 liters of water;

Ethersulfonate - 30 g per 10 liters of water;

Soap-kerosene emulsion 10 g of kerosene and 5 g of soap per 1 liter of water; the solution is thoroughly mixed;

Onion gruel (grated);

Garlic infusion (3 medium cloves per 1 glass of water; leave for one day in a sealed container);

Lemon affected by spider mites

Red or spider mite
The pest weaves around the underside of the leaf, where it settles. Insects small sizes(up to 0.4 millimeters), so they cannot always be immediately detected with the naked eye. The juice of the leaves provides food for insects, so the leaves turn yellow and dry out prematurely. Ticks appear more often at low air humidity and high temperatures.
Control measures:
Pollination with sulfur is used against red mites.
To kill ticks, the same pesticides are used as in the fight against scale insects and scale insects. If there are no pesticides, you can spray the plants daily with a strong stream cold water, especially the underside of the leaves.

Indoor lemon diseases: causes and treatment

Many vegetable growers mistakenly assume that at home a houseplant will not be susceptible to diseases and pests. However, a lemon growing at home is still a plant. Therefore, the risk of a disease or tick still exists. Don't panic ahead of time. In this article we will tell you what lemon diseases exist and how to deal with them.

Causes of diseases in homemade lemons

Disease can occur in a houseplant for many reasons. The main ones are:

• poor quality soil;
• inoculum;
• containers that have already been used before;
• weakened immunity resulting from improper watering, air temperature, fertilizer, lighting, pruning;
• weakened immunity caused by a previous illness;
• ingress of spores, various viruses and bacteria during summer ventilation;
• viruses and bacteria that entered the apartment “thanks” to insects;
• mite.

There are many other reasons. However, they are less common.



Harmful insects for indoor lemon

The main pest of citrus fruits is aphids. It destroys the leaves of the plant, then spreads to the branches of the tree. At the same time, aphids select the youngest and most tender leaves. What does the pest look like?



This insect is small in size, has a light green color. First the pest strikes inner part leaves, which is why it is so difficult to notice on early stage infection. Then the insect takes over the entire plant along the branch. The first sign of an aphid infestation is curling of the leaves of your homemade lemon. The insect can get onto the citrus from another indoor plant, for example, fuchsia.

This culture is a favorite delicacy of aphids. You can harm your lemon by bringing wildflowers home. The pest can hide in the soil, and suffer from it different cultures. Therefore, if you take untested soil after other plants or even another lemon, you risk completely destroying your indoor tree.

However, you should not immediately give up on the plant. The success of the fight depends on how quickly you identify the disease. If the pest has not managed to spread far, then it will be enough to cut off the infected branches and crush the pests.



Many gardeners use traditional methods. For example, an infusion of garlic helps against pests. To prepare it, use eight heads of garlic. They should first be cleaned and ground. Ready mixture mix with water in a ten-liter bucket and leave for one day.

The infusion will be ready after you express it.
If the aphids appeared due to poor-quality soil, then the soil will need to be replaced. Before this you need to prepare the plant. Place the lemon in a contact insecticide solution or garlic infusion. However, this time the concentration of the drug should be half as much as when fighting aphids.

Another pest of homemade lemons is the scale insect.



In this state, it cannot resist bacterial and viral diseases. However, there is control for this insect too. As with aphids, garlic water, insecticides, and a soap solution work well. The soap infusion is prepared as follows: two tablespoons liquid soap dilute in a liter of water. Then treat the infected leaves with this preparation. After sixty minutes, thoroughly rinse the soap from the lemon. It is recommended to repeat the procedure after two or three days.

Spider mite



An ordinary spider mite can also destroy a plant. He is also not averse to eating young citrus leaves. The main sign of the pest is the characteristic cobwebs on the leaves of the plant. Very often, spider mites appear on crops growing in dry air conditions.

Spider mites are afraid of moisture. To combat ticks, use a one percent solution boric acid. Most often, one spray is enough to kill the tick. However, if the tick does not give up, then repeat the procedure four or five times. An interesting fact is that pest control is equal to the prevention procedure against viral diseases.

Viral and bacterial diseases

Sooty fungus



Some of these diseases can be treated quickly and painlessly for the plant. However, there are diseases that are difficult or even impossible to treat. Such a disease is sooty fungus, which greatly weakens the plant, leading to drying out and weakening in growth. You can recognize the disease by an ashy coating on the leaves. It is not difficult to cure the plant. You need to rinse it with warm water using a dish sponge. It is recommended to ventilate the area where the lemon was before placing it back.



Another disease is scab. It affects the leaves and branches of the plant. Scab is characterized by the appearance of spots on lemon leaves that gradually darken and become soft. Diseased areas of the lemon rot and fall off. The disease is spread by wind or insects. The fight against the virus must begin with preventive measures. IN spring period treat the culture with a two percent solution of copper sulfate. If the disease does appear, immediately destroy the affected areas of the plant. Treat the rest with Bordeaux solution.

Wartiness



Another fungal disease that can infect indoor lemons is warts. Judging by the name, you can tell main feature diseases. The fact is that growths form on the leaves of the crop. However, they are not at all as harmless as they may seem. The fungus depletes the plant and destroys the future harvest. The methods of fighting are the same as with scab.

Root rot

The infection is much more difficult to deal with. The most common lemon diseases are gommosis and root rot. The first infection is characterized by rotting and cracking of the tree bark. In this case, you need to water the crop with warm water.



The main purpose of root rot is clear from the name. The infection affects the roots of the plant. If the lemon leaves wither, the branches dry out, and the leaves begin to fall off prematurely, this means root rot. The infection control measures are as follows. Remove the tree from the container and clean the roots from the soil. We sterilize the affected soil. Pour new soil into the container.

We cut off the rotten areas with a knife. Place the lemon root system in a solution of potassium permanganate for about sixty minutes. Next, the plant is removed from the solution and slightly dried. Treat the cut areas with wood ash. Then we plant the treated plant in a new place of growth. However, the work did not end there. You need to keep a close eye on your lemon and constantly fertilize it.

So, we have listed the main diseases of lemon, and also told what their treatment is. Lemon pests are no longer a problem for you.

Fighting diseases of indoor homemade lemon

Homemade lemon, like any other citrus crop, is susceptible to many diseases. These can be infectious, viral, fungal diseases, as well as diseases resulting from improper plant care.

Diseases of indoor lemon often occur due to a lack of microelements. For example, if a citrus tree lacks nitrogen, small, light yellow spots appear on its leaves. With a lack of phosphorus, the leaf plate becomes dull and its edges dry out. If a tree lacks iron, a light green net appears on its leaves; if there is a lack of manganese or boron, the ovaries fall off. To prevent this, you should regularly add mineral and organic fertilizers. It is important to follow the dosage, since an excess of fertilizers also negatively affects the condition of this plant.

Lemon diseases at home and their photos

Lemon diseases at home can be caused by pathogenic microorganisms: fungi, viruses, bacteria, mycoplasmas. Affected individuals develop various defects(shrinking, deformation of fruits and leaves, spotting, growths and others). Pathogens are spread by the wind, by insects, and also through drops of water during watering and spraying.

Most often, weakened trees are susceptible to diseases, so it is important to create everything when growing lemons. the necessary conditions for its full development, implement proper care, conduct regular, thorough inspections. The fight against lemon diseases should be carried out when the first signs appear. All affected parts must be cut off from a diseased individual so that they do not weaken the tree.

Most dangerous diseases homemade lemons:















To prevent and eliminate pathogens of fungal and bacterial diseases, the biofungicide “Fitosporin” is recommended, which is used to water and spray citrus.

This disease occurs in the lower part of the trunk. Gradually rises up onto the branches and down onto the roots of the tree. In the affected areas, bulges form in which gum accumulates, which is a yellow or brown liquid that hardens in air. The affected areas crack and die. Wounds appear on the tree. When a lemon is severely damaged, the leaves dry out and fall off. Individuals infected with gommosis continue to produce crops, but their fruits become smaller and lose their taste qualities. If measures are not taken to eliminate this disease, the citrus will die.



Gommosis often affects leaves and fruits. Brown spots appear on the leaves, which grow over time. On affected fruits, the skin darkens and becomes rough. The pulp softens, rots and acquires an unpleasant odor.

Treating this disease is quite difficult. Diseased areas are cleaned and treated with a solution of copper sulfate. After this, the tree is removed from the soil, its roots are cleaned and replanted in fresh soil. Diseased bark and wood are cut out, and all scraps are burned.

Scab and other diseases of lemon leaves

Lemon can also be affected by scab, which can be recognized by raised spots that appear on the leaves, branches, and citrus fruits. After some time, instead of these spots, holes form, after which the leaves fall off, the fruits and bark of the branches crack. The causative agent of scab is a pathogenic fungus that can overwinter in fallen leaves and spread by wind and insects. Grows quickly in a humid environment.

To prevent this disease in the spring, the crown and soil should be sprayed with a solution of copper or iron sulfate. The diseased plant is sprayed with Bordeaux mixture after bud break. Secondary spraying is carried out after flowering. To do this, you can use copper oxychloride, cuprosan and other fungicides.

The affected parts of the lemon must be collected and burned. Change the soil. In the spring, before the buds swell, remove all diseased branches. The tree is sprayed with mineral fertilizers. For this, urea (10%), ammonium nitrate (10%), nitroammophosphate (10%), calcium chloride (70%) are used. The drug “Strobilin” is effective in the fight against scab.

Sooty fungus

It appears on the leaves, later on the branches and trunk in the form of a dark coating. This disease slows down the growth of the plant and prevents its normal development.



If signs of sooty fungus appear, the plaque is washed off with clean warm water. It is useful to rinse the wood in the shower. The room where the affected lemon is located must be well ventilated.

Wartiness

Wartiness is one of the diseases of lemons that occurs in room conditions. Young shoots, fruits and leaves are attacked by a pathogenic fungus.



Small yellowish spots appear on the leaves, which after a while turn into gray warts. On shoots, warts increase in size, forming large growths, which leads to the death of the shoot. Brown spots form on the fruits and the ovaries fall off. Warts develop quickly in extreme heat and high humidity.

To eliminate this disease, the affected parts of the plant are cut off and burned, then the crown is sprayed with Bordeaux mixture. The first spraying is carried out in March, the second immediately after flowering, the third in July.

Root rot on lemon

Root rot on lemons is not noticeable until intense leaf fall begins. When this sign appears, the tree is dug up and the root system is examined. If there are lesions, they are removed using a sharp knife. After this, the citrus is transplanted into fresh soil and placed in a bright place. There is no watering for the next few days. The leaves are wiped with a damp cloth.



Sometimes when root rot appears, dark brown spots appear on the trunk through which dirt seeps. Over time, the bark dries out and dies.

Photos of the above diseases of indoor lemon can be seen below:













Viral diseases of lemon

Homemade lemon diseases such as citrus canker, leaf mosaic and tristeza are viral.



Citrus canker appears as dark brown spots on leaves and fruit. At long illness leaves fall off, fruits are formed with defects. This disease leads to the death of the plant. Cannot be treated.

To prevent cancer of citrus fruits, spring treatment tree with liquid copper fungicide.

Leaf mosaic is recognized by light, sometimes dark green stripes or strokes on the leaves. Leads to deformation sheet plate, as well as to slow down the growth of the tree. Cannot be treated. At good care and regular feeding becomes less pronounced.



Tristeza - leads to drying out and falling of leaves. With severe damage, branches, bark and entire trees die. Cannot be treated.

Lemon disease - sticky leaves

Quite often, citrus owners are faced with deformation, drying and falling of its leaves.

Lemon leaf diseases occur due to various reasons. It could be a lack of nutrients poor care, pest damage, tree disease.

The cause of leaf fall is often a lack of light, dry air or too high an air temperature. Watering with cold and chlorinated water, excess moisture in the soil, and disturbance of the acid-base balance of the soil have a negative effect on the leaves and the plant as a whole. In addition, lemon leaves react sharply to any changes, be it moving it to a new place or changing the temperature.

In some cases, citrus leaves become sticky. Sticky leaves lemons look like they've been sprayed with syrup. This disease is usually caused by a scale insect that has settled on a tree. If measures to combat this pest are not taken in a timely manner, sooty fungus may develop in the sticky liquid. To remove sticky deposits, wipe the leaves with a solution of transformer oil (6 ml per 1 liter of water). After 5-7 days, re-treatment is carried out. The solution not only effectively removes sticky coating, but also destroys the young scale insect, which has not yet become covered with a protective shell. If treatment is not carried out, the plant will die.

You can use another method of treating the tree. In the warm season, citrus is sprayed with karbofos or tobacco solution. To completely eliminate the disease, 2-3 such treatments are required with an interval of 7-10 days.

Characteristic signs of lemon diseases are presented in the following photos:

Indoor lemon diseases

Indoor lemon- a living creature, so he too may have problems. Troubles that happen to lemons can be divided into three groups: improper care, pests, diseases.

Failure to comply with plant care rules (watering, lighting, temperature, lack of nutrition, replanting and soil pH imbalance). With insufficient watering, the tree dries out, with excess watering, yellowing of the leaves appears and rotting of the root system occurs.

The deficiency of a particular microelement can be determined visually. With a lack of iron, the leaf, which has a rich green color, first becomes “speckled” (alternating green and yellow spots), then fades, turns yellow and dries out.

With a lack of phosphorus, the leaves become earthy-rusty in color and the tips of the leaves dry out. With a lack of potassium, the leaves shrink, forming “wrinkles” and folds.

With a lack of manganese and boron, the ovaries crumble. Correcting the situation is much more difficult than watering the lemon in time with special fertilizers for citrus fruits.

Lemon pests and ways to combat them

Scale insects and false scale insects(larvae are hidden by a shield dark brown). If they are present, the leaves fall off, the branches dry out, and the plant slowly dies. Pests must be cleaned off (with a toothbrush or a sharp stick), and the lemon must be washed with soap emulsion. You will learn about another way to combat these pests from the video.

Spider mite(red citrus mite). The larvae are located on the underside of the leaf; in this case, the leaf is shrouded in a web, which gradually envelops the entire plant. Leaves become discolored, dry out and fall off, flowers and fruits are damaged. Spider mites are more likely to appear in dry indoor air. If you are affected by spider mites, you can spray the lemon with a 0.15% Actelika solution. Spraying will have to be repeated three times with an interval of 10 days.

Mealybug(larvae and females feed on the entire aerial part). If they are present, sticky insect secretions appear on the surface of the leaves, later the leaves dry out, spots and cracks form on the fruits. The fruits fall off before they are ripe. The plant must be periodically inspected and the larvae and females of mealybugs mechanically destroyed.

Citrus aphid(small insects of black or yellow-green color). The tops of young shoots are paralyzed. If they are detected, you need to spray the lemon with a 0.15% Aktelika solution. Spraying will have to be repeated three times with an interval of 10 days. To prevent aphids from appearing, you can place a pot of fragrant geranium next to the lemon.

Thrips(they look like a black line on the leaves, they are so small). They crap more than they suck the juices from the plant, they can fly, and spread viruses. To destroy them, you need to wash the tree out of the shower (cover the soil with film) and treat it with soap emulsion.

Whitefly(white small moth). The greenish-white larvae are located on the lower part of the leaves. Getting rid of them is quite problematic. In this case, the lemon is sprayed with insecticides at least 5 times every 3 days.

Diseases of indoor lemon and methods of treating them

Indoor lemons can suffer from many diseases, the causative agents of which are fungi, viruses, bacteria and mycoplasmas. The result of their influence is a variety of spots, ulcers, rot, wilting, growths, growths, etc. Harmful microorganisms are spread by insects, drops of water during spraying and watering, and wind.

The symptoms of infection of indoor lemons by bacteria and fungi are similar, but with an infection caused by fungi, along with increasing spots, fungal spores are visible on them - gray plaque, brown pustules or black spots of sporulation.

Diseases most often appear on weakened plants, so proper care of lemons at home, pest control, cutting out affected parts of the plant, processing the cuts (you can activated carbon). It is better to immediately remove all flowers, buds and fruits from a diseased lemon so that they do not weaken the plant.

To suppress many pathogens and for prevention, it is effective to use the biological product “Fitosporin” (the drug is non-toxic and odorless). They are sprayed and added to water for irrigation according to the instructions. You can spray 2-3 times with a 1% solution of Bordeaux mixture.

Anthracnose– the most common disease of lemons, caused by a pathogenic fungus. With anthracnose, the buds fall off, the leaves turn yellow and fall off, reddish spots appear on the fruits, and the branches die. It is necessary to trim off dead shoots and carry out the treatment described above.

Scab(citrus warts) – also frequent illness, mushroom nature. In this case, small transparent yellowish spots appear on young leaves, turning into pink-gray warts. Warts grow over time, forming a growth, and then the shoot dies. Orange spots appear on the fruits, increasing in size, they become red-brown in color, and the ovaries fall off. The affected parts of the plant must be cut off and burned, and the lemon crown should be sprayed with a 1% solution of Bordeaux mixture.

Gomoz(gum bleeding) manifests itself as longitudinal brown-red spots on the branches and trunk of the lemon. The bark in these places gradually dies, and a sticky golden liquid flows out of the cracks, which hardens in the air.

There may be several reasons for this disease: deep planting of seedlings, undisinfected soil, lack of drainage, excess nitrogen, lack of phosphorus and potassium, mechanical damage, too much high humidity air.

To treat homosis, it is necessary to find out the cause of the disease and eliminate it. The affected areas on the trunk must be cleaned with a sharp knife, cutting out the affected areas, disinfected with a 3% solution of copper sulfate and the wounds covered with garden pitch. It is recommended to treat the wound several times until complete healing. It is better to cut out the affected thin branches and burn them.

Sooty fungus can settle on lemon when infected with scale insects and mealybugs. To prevent it from appearing, it is necessary to combat pests in a timely manner.

Inspect your lemon frequently so you can spot pests and diseases early. During Taken measures will not cause much harm to the lemon.

Lemon diseases



Lemon trees, like other indoor plants, can be affected by viral and infectious diseases and pests.

Although this does not happen often, it is better to find out what lemon diseases exist and how they affect external condition plants, and what are the methods of treating them. Let's find out what viruses and infectious diseases affect indoor lemongrass, what pests it may be attacked by, and what to do in such cases.

Why does a lemon get sick?

Lemon is easily susceptible to diseases and attacks by pests and viruses in the following cases:

• If he did not have time to get stronger after recovering from other illnesses.
• If it is provided with poor care: contaminated soil, poor lighting, illiterate pruning, insufficient soil fertilization, improper watering, etc.
• If a virus or pathogenic bacteria was brought by insects or a diseased cutting during grafting.

Viruses and bacteria can enter the plant when ventilating the room, but this happens quite rarely.

Most often, viruses, bacteria and pests infect the leaves of indoor lemons. However, if a lemon drops fruits and leaves, the reason for this may be a lack of microelements:

• If the light-colored leaves have a pronounced network of green veins, the lemon needs manganese, zinc or iron. Another reason is disturbances in soil pH.
• If an adult leaf loses its gloss, dries out at the ends and turns reddish-brown, the plant does not have enough phosphorus.

Why does a lemon drop its leaves?

• If pale yellow specks appear on the leaf, and it turns yellow and dull over time, this indicates a lack of nitrogen.
• If grooves appear between the veins of the leaves, the lemon needs potassium supplementation.
• If a plant drops its ovaries, it urgently needs manganese.

Too frequent feeding is also not beneficial for the plant. If leaves fall on a lemon, what should you do in this case? Hold off on feeding and evaluate the correctness of care: suddenly you are doing something wrong.

Viral diseases of indoor lemon

Let's learn about three viral diseases that cause lemons to shed leaves: why they often lead to the death of the plant, and whether they can be cured:

Sheet mosaic

Having become ill with it, the leaves become covered with dark or light strokes in the form of a mosaic and lose their shape. The growth of the tree noticeably slows down.

This disease cannot be cured by any means, but symptoms can be reduced by regularly fertilizing the soil and providing the plant with proper care. If you have other lemons, it is better to destroy the plant affected by the virus as soon as possible.

Citrus cancer

When infected with this virus, brown spots appear on the foliage and fruits. When the form is neglected, the leaf falls off, the lemons take on an ugly shape, and a little later the tree dies.

It is impossible to cure citrus cancer: to prevent it in the spring, we treat the plant with liquid copper fungicide.

Tristeza

Having picked up tristeza, the lemon loses its foliage, the bark or twigs die off. The plant dies - it cannot be cured.

Most often, viruses infect weakened lemons that are poorly cared for.

Lemon diseases: description and treatment

Fungal and infectious diseases of indoor lemon

Let's consider the main diseases of lemons, which are fungal and infectious in nature, their symptoms and methods of treatment.

Most often, indoor lemons are affected by the following fungi and infections:

Gomoz

With homosis, the branches and trunk of the plant become covered with elongated spots of a red-brown hue, under which the bark quickly becomes dead and cracks. The cracks ooze a sticky golden substance that hardens quickly.

Causes of homosis: excessive humidity in the room, cuts or breaks in the bark, deficiency of phosphorus and potassium, excess nitrogen fertilizers, diseased soil or deep deepening of the trunk.

How to treat homosis? We cut off all the spots from the bark of the trunk, treat the sections with a three percent solution and use putty from garden pitch. We repeat the treatment until spots stop forming on the trunk bark. If the branches are covered with spots, cut them off entirely and destroy them.

Anthracnose

This is a fungal disease in which leaves fall off the lemon, and many people do not know what to do about it. First the leaf turns yellow, then flies off, as do the buds. The branches of the plant gradually die off, and red spots appear on the lemon leaves.

To get rid of the fungus, we destroy the dead branches and spray the lemon with Fitosporin or a one percent solution of Bordeaux mixture. We spray three times.

Scab

Another fungal disease of indoor lemons is scab, in which young leaves become covered with transparent yellowish spots, gradually turning into pink-gray growths. Spreading over the leaf, these growths destroy it along with the shoots. When scabbed, fruits become covered with orange spots, which over time become red-brown. At the same time, the lemon drops its fruit.

In order not to destroy the entire plant, we cut and destroy all affected parts of the plant, and spray the crown with one percent Bordeaux mixture.

Melseko

With melseco, the lemon shoots dry out, the foliage falls off, starting from the tips of the branches, and the cut of the branch turns red.

Poor lighting is to blame for this lemon disease: in winter the plant did not have enough light, and it was not illuminated.

There is no treatment for Melseco: we monitor the plant, and if it continues to hurt, we destroy it.

Root rot

If a lemon suddenly drops a leaf, dig it up and inspect the roots. Having discovered rotten roots, cut them off and replant the lemon in new, disinfected soil.

We place the transplanted plant on a light windowsill and avoid watering for a week - just wipe the leaves with damp gauze or a sponge.

Pests of indoor lemon

In addition to infectious and viral diseases, indoor lemons are affected harmful insects. Let's find out which pests attack lemons grown at home and how to deal with them.

Shchitovka

Scale insect larvae settle on the underside of leaves and subsequently move to outside. The plant withers, dries out, and quickly picks up viruses and infections.

To get rid of scale insects, we use a special insecticide or soap solution, for which we dilute 2 tbsp in water (1 liter). any liquid soap. Wet it soap solution all places affected by insects. We wait one hour, rinse the plant in the shower and repeat the treatment a couple of days later.

Pests of indoor lemon

Common aphid

Colonies of light green aphids usually settle on young shoots that are not overgrown with bark. First they attack the bottom of the leaf, then move to the top, simultaneously sucking out the juices. The foliage curls up and dies.

If there are only a few aphids, we cut off the affected shoots and destroy them along with the insects, after which we feed the plant with complex fertilizer. If aphids have covered most indoor lemon, spray the tree with insecticide or garlic infusion, for which we peel 4 heads of garlic and soak them in 5 liters for 24 hours. Then we filter.

Spider mite

These insects often attack young twigs and leaves. The foliage curls up and a cobweb appears around it. Lack of air humidity is to blame for the appearance of spider mites.

To get rid of insects, spray the tree with a one percent solution of boric acid, performing the procedure four times.

Root aphid

Unlike ordinary aphids, root aphids found in contaminated soil attack the roots.

To exterminate it, we transplant the lemon into disinfected soil, treating the roots with a contact insecticide or a weak garlic tincture.

In many sources you can find advice on treating lemon with an alcohol solution - this is strictly prohibited. Lemon does not tolerate alcohol.

As you can see, lemon diseases are numerous and sometimes very serious: some lead to the death of the plant. To protect it from harm, plant the plant only in disinfected soil, give it a regular shower and wipe the foliage and branches with wet gauze, treat the crown with soapy water once a month, and inspect the tree more often for diseases or insects.

Lemon: diseases and their treatment



Diseases of indoor lemon can be of fungal, viral and bacterial origin. They spread through insects, water droplets during watering and spraying. It is important to remember: a healthy plant is less susceptible to disease than a weakened one. That is why at home it is simply necessary to provide the flower with proper care and microclimate. The main thing in treating a flower is correct and timely diagnosis and adequate actions to eliminate the disease. So, diseases of indoor lemon, their description with photos, effective treatment from specialists.

Typical diseases of indoor lemon and their treatment

Why do lemon leaves turn yellow and curl? Why does the plant shed its leaves? Why do lemon leaves become covered with black spots? The cause may be improper care, lack of microelements or flower diseases. If the leaves fall off, it means that the homemade lemon may lack light; it has been overwatered. Lemon leaves fall off if the air in the room where it is located is dry or the horse system is disturbed.



Most often, lemon leaves fall in the autumn-winter period, but leaf fall can occur at any other time of the year. main reason: unfavourable conditions . For example, a recently purchased plant may lose its leaves. The explanation is simple: in the greenhouses where it is grown, the conditions are different from the microclimate in the apartment. Leaf fall is a reaction to a change in the growing microclimate. After purchasing, the lemon must acclimatize to the new conditions; it is not advisable to replant it; it is provided with proper care. At this time, it is important not to overwater the flower, since without leaves the process of moisture evaporation is disrupted. Experts recommend spraying more than watering; you can add epin to the solution.



Why does a lemon shed its leaves if its growing location has not changed? Reason: lack of light. This plant belongs to the category of light-loving, that is, it needs a 12-hour day of light. In the autumn-winter period, when the length of daylight hours decreases, the plant must be illuminated with a fluorescent lamp. It is better to place the pot on the western or eastern side of the house, or on the southern side, but with obligatory shading.

The lemon dropped its leaves if it was replanted with a complete or partial replacement of the soil. In this case, the root system is disrupted, which necessarily affects the crown. She crumbles. What to do? We need to help the flower restore its root system. To do this, watering is reduced, the flower is placed under a greenhouse ( polyethylene film), which should not touch the leaves and branches of the flower. Spraying is carried out to maintain high level humidity in the greenhouse. Every day the greenhouse is ventilated for 15 minutes to prevent the formation of condensation. Epin is added to the spraying solution once a week, and root can be added to the watering solution. There is no need to suddenly remove the greenhouse. To adapt the flower, increase the ventilation time every day. The greenhouse is completely removed when new leaves appear on the lemon.

Lemon drops leaves when it is attacked by cancer, viral mosaic. All these diseases are viral in nature. In most cases, diseases cannot be treated when grown indoors, and the plant is completely discarded in order to prevent infection of other flowers.



Cancer on lemon leaves looks like brown spots irregular shape, which dry out and crumble inside. With prolonged disease, young lemon leaves develop deformed and small. The disease cannot be cured, it can be prevented spring spraying flower with fungicides.



Leaves fall if homemade lemon is affected by leaf mosaic. On the leaves it looks like light spots of irregular shape, sometimes spreading across the plate in the form of streaks. Mosaic cannot be treated; in most cases, the plant is removed.



Lemon leaves curl if the watering schedule is disrupted. This is drying or waterlogging of the soil. In the first case, you need to water the flower with small portions of water, but do not allow the soil in the pot to become waterlogged. In both cases, the plant is placed under a greenhouse, where it is regularly sprayed. Overmoistening the soil in a pot leads to rotting of the roots. Damaged roots can no longer “drink” water, and therefore the plant suffers from moisture deficiency even in waterlogged soil. In this case, watering is stopped. The lemon is taken out of the pot, but the integrity of the earthen ball must not be damaged, and it is wrapped in paper. The latter will draw out excess moisture from the soil. Drying in this way is carried out for 3 days, the plant needs to be shaded. Then the flower is returned to the pot and a greenhouse is organized for it. Watering is not carried out, much attention is paid to spraying.



Lemon leaves dry out around the edges if the room temperature is high and the humidity is low.. Optimal temperature regime for lemon +20. +23 degrees, humidity - not lower than 70%. Otherwise, the plant gets sick. Very often the leaves of indoor lemons turn yellow if they are placed close to heating appliances in winter. The plant does not like dry air, and even in winter it may suffer from lack of light. It is illuminated with a fluorescent lamp.



The leaves turn yellow and fall off if the lemon is infested with spider mites.. In this case, on back side leaf plate will be present white coating, and on the branches there is a light, whitish cobweb. The leaves are covered with small spots. How to treat? It is necessary to wash the plant in the shower with warm water, then treat it with one of the preparations Fitoverm, Vertimer (three times with an interval of 10 days) or Akarin, Neoron (4 times with an interval of 7-10 days). It is better when the affected flower is isolated from the rest of the collection.

Almost anyone can recognize this tree at first glance with its attractive golden fruits and aroma familiar from childhood. And why not try growing it at home. To make the experiments more productive, we recommend arming yourself with knowledge of how to properly care for lemons.

Varieties suitable for self-cultivation

There are several varieties that grow and bear fruit well in apartments. The Pavlovsky variety can be called one of the best indoor lemons. This tree with leathery leaves and spines can reach a height of 1.5 to 2 meters. Fragrant flowers mainly appear in spring and autumn. The first fruits appear at the age of three.

The fruits have a thin skin and a nipple at the top and are colored light yellow. Ripe lemons weigh between 200 and 300 grams.

"Meyer". Trees with a small number of thorns and a rounded crown reach a height of 1 to 1.5 meters. It blooms powerfully throughout the year.

The fruits, colored bright yellow, weigh from 50 to 80 grams. "Meyer" stands out among other varieties excellent harvest(up to 50 lemons per year).

"Novogruzinsky". Trees grow up to 1.5-2 meters. The fruits, weighing 120-150 grams, have an elongated oval shape with a wide blunt nose.

Its undeniable advantage is its good adaptability to growing indoors. The disadvantages include low yield (no more than 10 fruits per year).

"Kursky". The trees reach almost 2 meters. The fruits weigh up to 300 grams. This variety must be pruned every year and the crown must be formed, as well as regularly fed.

"Ponderosa" The trees, which have a spreading crown and are covered with thick thorns, bear fruit weighing about 500 grams. The advantages include early fruiting (in the 2nd year), good tolerance high temperatures and dry air, and the disadvantages are low yield (up to 5 fruits).

About containers for planting, soils and drainage

For lemons, the best pots are made of red clay, not covered with glaze. They allow the roots to breathe because they allow air to pass through and remove excess moisture.

Soil for lemon trees can be picked up in special stores or centers, but it is also easy to make it yourself. To do this, you will need leaf humus, sand (river), high peat, turf soil, and take one part of the sand, and turf land, peat - two parts.

Important! For young plants, the soil should be lighter and looser (add an additional two parts of peat), and for adult plants it should be more dense (due to turf soil).

Any container for growing lemons must have drainage at the bottom. The size of the layer is from 2 to 5 cm. It is best if it is small expanded clay.

Temperature

Temperature has a great influence on the growth and development of this crop. During the period of buds and flowering, 14-18 degrees is considered optimal. Fruits grow best at 14-24 degrees, and the greatest growth occurs at 21-22 degrees. In autumn and winter, it is better to keep plants in a bright place at 4-15 degrees.

Important! Big changes temperatures between day and night can cause leaves to dry out and fall off. Also, leaves fall at temperatures above 35 and below 5 degrees.

Lighting

For good development lemon, the length of daylight hours should be about 12 hours. Therefore, in winter, plants need to be illuminated fluorescent lamps or special phytolamps. If it is not possible to organize additional lighting, then it is advisable to lower the temperature to 12-14 degrees.

Important! This plant really doesn’t like being moved from place to place. To ensure that the branches grow evenly in all directions, the pots are periodically turned.

Growing technology

Lemon care at home consists of watering, fertilizing, replanting, pruning and crown formation.

Watering and air humidity

A well-developed lemon tree constantly needs regular watering. However, if the soil is always damp, the roots suffocate from lack of oxygen, the substrate turns sour, and brownish spots appear on the leaves and they begin to fall off.

Watering the plant should be done carefully and preferably with soft water (temperature 22-24 degrees). Excess water from the pan is removed after half an hour.

Important! IN summer period The lemon is watered only when one third of the earthen clod has dried out. And in cold weather, watering begins when two-thirds of the soil in the pot becomes dry.

The best air humidity for this plant is considered to be 60-70%, but in apartments it usually ranges from 25 to 35%. Therefore, to increase humidity, the crown must be sprayed with warm water.

Transfer

It is best to transship this crop in the second and third ten days of February until the shoots begin to grow, avoiding damage to the roots.

Young lemons need to be transplanted annually, and adult lemons – after 3-4 years. In this case, the container is taken 3-5 cm larger, and the tub – 8-12 cm. After transshipment, the plant is watered and placed for 2-2.5 weeks in a warm and shaded place.

Plants need to be replanted when the roots completely entwine the soil in the pot and are visible from drainage holes. Removed during transplantation top part soil, remove the blackened roots, and trim the ends of the rest. This procedure gives impetus to the formation and growth of roots.

Feeding

The lemon tree is demanding in terms of nutrition, especially at the beginning of growth and during fruit formation. Both organic and mineral fertilizers are used for fertilizing. They are added every 15 days.

From mineral fertilizers use saltpeter (5 g per l), potassium salt (2 g per l) and superphosphate (5 g per l). Sometimes it is good to add magnesium sulfate (1 g per liter). And from organic matter - infusions of cow or bird manure, which should be infused for at least 2-3 weeks.

Important: The temperature of the fertilizer solution should be 3-5 degrees higher than room temperature.

Before growth begins, trees are generously treated with a solution of iron sulfate (2 g per liter).

Reproduction methods

Lemon can be propagated air layering, seeds, cuttings and grafting (budding).

Growing from a seed

It’s not that difficult to get lemon from a seed at home. It is advisable to plant the seeds immediately after they have been removed from the fruit. They are placed in small containers with light, breathable soil at a depth of 1 to 2 cm. In a moistened substrate, they begin to sprout after 2-3 weeks, but the first fruits from such lemons can only be obtained after 8 or more years.

To speed up the appearance of the harvest, you need to graft a one-year-old seedling (with a trunk diameter of at least 1.5 cm) with a cutting or bud taken from a fruiting lemon. The grafted plant begins to bloom within 2 or 3 years.

Graft

Much has been written about how to graft a lemon. But it is worth repeating the main points of this technology. For grafting, a cut is made in the shape of the letter T on the bark of the seedling (rootstock) and a bud (eye), which was taken from a fruit-bearing specimen, is inserted into it. The place where the grafting occurred is tightly bandaged with tape from bottom to top. The best time March and July are the months for this.

We take cuttings

You can easily and quickly get a fruit-bearing tree using cuttings. It is best to do this from April to May. Cuttings are cut from young branches of a healthy tree, 8 to 15 cm long with 3-5 leaves.

Cuttings cut at right angles take root most quickly. To prevent the bottom cut from rotting, it is sprinkled with crushed coal.

Rooting of cuttings occurs in damp sand at a temperature of 20 to 27 degrees in a place inaccessible to the sun. Heating the soil to 27 degrees can accelerate the appearance and growth of roots.

The chopped shoots are buried 1.5-2 cm, sprinkled with water and covered plastic bag or a jar. In 1.5-2 months, the cuttings take root completely.

Important! Before you start rooting the cuttings, it is advisable to soak them in a heteroauxin solution. This will speed up the formation and growth of roots.

Ready seedlings are transplanted into soil consisting leaf soil, sand and turf (2/1/0.5).

About diseases and pests

Among the diseases of homemade lemon, the first place is occupied by root rot, which occurs when the soil is very waterlogged. Because of this disease, the roots become brown, quickly rot and die.

And here gray rot, which manifests itself in the form of brown-black spots on the leaves, or fusarium, in which leaves fall off and shoots die, are quite rare. Affected parts of plants must be pruned.

When rust appears, plants are treated with topaz.

Whitefly, spider mites, scale insects, mealybugs, thrips, aphids, leafminer flies - all these pests can annoy your green pet. If yellow spots in the form of dots appear on the leaves of the lemon, then most likely a spider mite has settled on them.

If there are a small number of pests, they are removed by hand, the leaves are wiped, and severely damaged shoots are cut off. In this case, lemons are treated with herbal preparations.

If there are a lot of insect pests on the trees, then they need to be sprayed with neoron, fitoverm, actellik and spark. It is worth remembering that one treatment is not enough, and they are repeated 2 or 3 times with a break of a week.
