Hibiscus diseases: types and description, features of care and treatment. Learn more about diseases and pests of Chinese roses and how to combat them Scab on hibiscus buds treatment

A small circle of friends and I were once lucky enough to have hibiscus plants at home - each of us had one tea rose in the most prominent place. Hibiscus has always shown itself to be an obedient flower, it was pleasant to deal with, it did not get sick or be capricious, but recently I noticed that the hibiscus began to get a little sick, so I had to look through everything possible diseases, in order to exclude inappropriate options and still find the root of the problem.

Hibiscus diseases can be caused by several factors: poor care, changes in weather conditions (this is especially true for garden hibiscus), as well as damage from viruses and pests.

As I learned, the diseases of hibiscus include: dark spots on sheets. The darkening of some areas of hibiscus leaves is caused by a fungus that infects the plant against the background of any changes; simply, a weak plant is easy prey for the fungus to colonize new territories. To cure hibiscus from this scourge, you need to constantly treat the leaves of the plant. There are special fungicidal preparations that perfectly combat the problem, as well as laundry soap, available at home, which, by the way, copes with most pests. It is necessary to exclude excessive moisture in the air or soil, so as not to give fungi a reason to actively develop.

Hibiscus can also be affected by mold. You may have noticed the first white coating on the lower leaves of the hibiscus, but do not give it any importance until the mold begins to spread to large areas of the hibiscus, and its general condition leaves much to be desired. Mold can be dealt with using similar principles as with fungus, only during the treatment period it is also important to exclude fertilizing, because active fertilizers will act in a completely unexpected way.

Viral infection. This disease is very complex, it is similar in symptoms and development to human cancer, although it is transmitted virally. You may notice yellow stripes on the leaves - these are places of infection, after which the hibiscus roots will rot. In a couple of months the plant will “burn out” and, unfortunately, you will no longer be able to enjoy its pleasant flowering and beneficial properties. The fight against a viral infection is fundamentally different from other methods of treatment: you need to completely destroy the plant, and remove the soil and the pot in which it was located. The key answer to the question “why should I do this?” there will be a “viral” infection. You risk infecting other plants that were blooming harmlessly nearby. In addition, if you want to propagate or replant or purchase a hibiscus, for some time you cannot put it in the place of the old hibiscus’s former habitat - after all, a virus is a serious matter.

Hibiscus is a fairly hardy plant and can forgive some mistakes in care. But, despite this, agricultural technology when growing “ Chinese rose» is very important and failure to comply will lead to pest infestation and disease development.

Chlorosis – this is a disease in which the green parts of the plant change their color to yellow, lemon or whitish due to a decrease in the amount of chlorophyll. This disease can be non-infectious and infectious.

Non-infectious chlorosis appears when there are disturbances in the plant’s nutrition: lack or excess of nitrogen, magnesium, potassium, iron. Potassium and magnesium are competing elements in nature. An excess of one leads to a deficiency of the second. Potassium is essential flowering plant. If it is deficient, the plant does not bloom, or the flowers are poorly colored and the branches are thin. A lack of magnesium leads to chlorosis. Iron deficiency also causes leaves to turn yellow and fall off. In order to prevent this, water for watering the plant must be settled and iron chelate added to it.
Infectious chlorosis caused by viruses, fungal microorganisms and pests. Cleaning from dust, timely application of fertilizers, replanting and pest control will help avoid these diseases.

Sunburn. Direct Sun rays, falling on a plant that has not yet adapted, partially destroys the chloroform in them, as a result of which the leaves become covered with white burn spots. This temporary phenomenon is observed if the flower is moved from a greenhouse or a place with insufficient light to bright sun. The hibiscus quickly gets used to changes in light, and new leaves will grow normally. To avoid loss of decorativeness and not to injure the plant, it must be accustomed to changes by exposing it to the sun for an hour a day, gradually increasing the duration of stay.

Diseases caused by pests

Greenhouse and tobacco whiteflies. When a plant is damaged, its leaves turn yellow and become covered with sticky secretions. Pale yellow larvae or adult white-winged insects can be seen on the lower surface of the leaves. To combat and prevent the disease, the plant is treated with solutions of potassium soap or with the preparations Biotlin, Fufanon, Aktara, etc.

Spider mite (web on hibiscus). The leaves of the affected plant become dull and become covered with yellowish specks. Subsequently, large dry areas appear on them. The underside of the leaves is covered with cobwebs in which the pest lives. To combat and prevent the disease, it is necessary to wash the leaves with soap or mineral oil, and also treat them with Molniya, Fitoverm, Akarin, etc.

Aphid. Aphids are attracted to young leaves and buds of the plant. When damaged, they become deformed and become sticky. To prevent and combat the disease, the plant is treated soap solution, tobacco dust, drugs Biotlin, Akarin, Decis, etc.

Scaleworms. White, waxy discharge appears on the petioles and in the axils of the leaves. To combat the disease, the plant is sprayed with Actofit or treated with mineral oils.

Scale insects and false scale insects. Brownish or pale brown tubercles appear on the stems of the plant. If the plant is slightly damaged, the pests are removed mechanically, and the affected areas of the plant are wiped with kerosene or mineral oil. In case of severe damage, it is better to treat the plant with an insecticide.

Bacterial spotting. The edges of the leaves of the affected plant become covered with rotting yellow spots. To prevent and treat the disease, the plant is systematically inspected and treated with Fundazol, Cumulus, Euparen, etc.

Brown rot. Most often it affects young plants and seedlings. The affected plant's stems turn brown and thin at the very base. To prevent the disease, cuttings and seedlings are treated with Rovral. Seedlings should be planted shallowly, spraying thoroughly after planting.

Vascular withering. Caused by fungi. The affected plant's branches and trunk quickly dry out, sometimes without having time to lose foliage. To treat the disease, the damaged parts of the affected plant are cut out and treated with an antifungal drug.

Midge gall midge. In affected plants, the buds turn yellow and fall off without even blooming. Midge midges lay eggs in tiny hibiscus buds, so To prevent the disease, yellowed buds are collected, not allowing them to fall, and the soil under the flower is treated with a preparation against soil pests.

Symptoms of diseases

Hibiscus leaves are turning yellow. The most likely causes of the disease are damage by pests (aphids, spider mite), diseases of the root system, insufficient air humidity or chlorosis of leaves. The causes of chlorosis are an excess of chlorine and calcium in irrigation water with a lack of nitrogen and iron. Water for watering the plant should be settled and iron chelate added.

Hibiscus leaves are falling. Stress, insufficient humidity. It is necessary to create rest for the plant and spray it.

Indoor hibiscus - leaves turn yellow and fall off. Stress, insufficient humidity, draft, waterlogging of roots in winter time. It is necessary to create rest for the plant, spray it, making sure that the bud does not turn into a liquid mess.

Why do hibiscus leaves curl?. The plant is affected by aphids. Needs to be treated for pests.

The tips of the hibiscus leaves are wilting. Lack of nutrients. It is necessary to feed the plant with nitrogen and phosphorus preparations.

The hibiscus is withering. The plant is too hot. It is necessary to reduce the temperature in the room, shade, spray.

Why does a hibiscus drop its buds? The plant is too hot. The soil lacks potassium fertilizers. The buds are affected by the gall midge.

What to do if he dies?

If your Chinese rose is sick, do not despair, it may be possible to revive it. Hibiscus is unpretentious and can be treated at home.

On this moment Many drugs have been developed for pest control; they can be purchased in specialized stores or used traditional methods, treating the plant with a solution of soap, tincture of tobacco or pepper.

Folk remedies for hibiscus pest control

Pepper tincture (against aphids, mites) – Dry pepper is poured with water in a ratio of 1:2 and boiled for an hour, then infused and filtered. To spray a plant, 10 g of the drug is diluted in one liter of water and soap. Soap should be about 5g per liter.

Tobacco tincture (against aphids, thrips, mites) – 1 kg of tobacco dust or tobacco is boiled in 10 liters of water for two hours. Leave for two days and filter. Before use, the concentrate is diluted in 10 liters of water with 50 g of soap.
Soap solution. To prepare the drug, 200 g of potassium soap is diluted in 10 liters of water.
Mustard tincture (for ticks, aphids) – Boil 50g of mustard in a liter of water and infuse. Before use, the concentrate is diluted in 20 liters of water.

Agricultural technology is of great importance when maintaining hibiscus: soil acidity, heat and light conditions, air and soil humidity. Create comfort for the flower: do not move it, treat it for pests, loosen the soil and water it once a week, and gradually the hibiscus will grow new leaves.

Known to most lovers of indoor flowers, the Chinese rose or hibiscus (Hibiscus rosa-sinensis) is considered an exquisite and luxurious plant and is grown by many gardeners at home. This indoor favorite attracts attention with its unusually bright and large red, pink, lilac, yellow or white flowers against the backdrop of rich, rich green foliage.

Hibiscus is a capricious plant; it must be cared for strictly according to certain rules. Indeed, with the slightest change in favorable conditions, the Chinese rose responds with the loss of its decorative qualities. Then suddenly the leaves begin to turn yellow, and then real leaf fall occurs. There is definitely an explanation for this behavior of an indoor flower. It is possible that this is due to disease or pests, or maybe the hibiscus is under stress. It is important for the gardener to quickly establish the cause of the negative changes and take urgent measures to save the plant.

Violation of the watering regime

Hibiscus over the age of four to five years needs daily large quantities irrigation water, as its root system requires it. During the break between waterings, the soil is flower pot should not be wet, but always slightly moisturized. An excess of moisture in the soil can lead to compaction of the soil and poor air permeability, which will lead to rotting of the root part and waterlogging of the soil surface.

Stagnant water and swampy soil create favorable conditions for the appearance of harmful bacteria and various fungal diseases. Under such conditions, the root system of the plant begins to slowly die. It no longer has enough nutrients for the growth and development of the flower, so the leaves begin to turn yellow and gradually fall off. This process must be stopped at early stage, then the hibiscus can still be saved.

Usually a young plant cannot cope with heavy watering. It is recommended to urgently remove it from the flower container, wash the roots, all rotten and blackened parts must be completely cut off. Then you need to treat all the cut areas and the remaining roots with fungicides, sprinkle them with the preparation “Kornevin” and replant indoor flower into a new flower container and fresh substrate. Immediately after planting, you need to spray the entire crown of the Chinese rose with a solution based on Epin.

In adult hibiscus, the leaves often turn yellow and fall off due to lack of moisture in the soil. Constant overdrying of the earthen clod depletes not only the root system, but leads to withering of the entire leaf mass. In this case, it is almost impossible to save the indoor plant.

Insufficient lighting

The rose can thrive in full sun and grows well in shady conditions. But sudden changes in light levels (for example, moving hibiscus from outdoors to indoors and vice versa) can lead to yellowing and loss of foliage.

When a flower moves into a poorly lit room, it is necessary to use fluorescent lamps and illuminate it for an additional few hours a day for a while in order to prevent the plant from falling into a stressful state. When moving hibiscus from the house to the street, it is very important not to immediately place it in direct sunlight, but to do it gradually. First, you need to shade the flower during the midday hours and protect it from sunburn.

Temperature violation

The Chinese rose prefers to be kept in warm conditions with temperatures from 18 to 30 degrees Celsius. Lowering and raising temperatures beyond these limits has an adverse effect on the plant. It is also not recommended to allow cold drafts and sudden temperature changes. In a cool room you need to install a heater, and in a hot room use spraying and raise the humidity level.

When fertilizing the soil with indoor plants, you need to know exactly what nutrients are important for a given plant. An excess or deficiency of certain substances can harm your pet. For example, elements such as magnesium and potassium are very important for the development of hibiscus and must be present in increased quantities. But a large amount of nitrogen and phosphorus can cause a change in the color of the leaves and lead to complete yellowing. There is even such a thing as a “nitrogen burn.” That is why experienced flower growers recommend choosing fertilizers that contain a lot of potassium, and without nitrogen-containing and phosphate fertilizers, the Chinese rose will not be lost. The nutrient mixture should only benefit the indoor flower.

Pests

One of the most dangerous and common pests of hibiscus is the spider mite. It is almost impossible to notice its appearance at first. The leaves of a houseplant turn yellow, wither and begin to fall off actively and in large quantities, and it is not immediately clear that the reason is the appearance of a pest. Only after some time can you see with the naked eye small black dots (with barely noticeable movement) on the thin threads of the web.

There is no way to do this without the help of various chemicals. Specialized retail chains for gardeners and flower growers offer drugs such as Fitoverm, Aktara, Actellik to combat spider mites. With their help, the crown of the bush and the entire plant as a whole are treated.

The appearance of the disease - chlorosis

This disease can completely destroy a plant in a short time. First the leaves die, and then gradually the shoots and the entire flower. Hibiscus suffers from chlorosis when the soil is moistened with hard irrigation water, with a large amount of alkali in the soil, with an insufficient amount of fertilizers and fertilizing, as well as with a lack of iron. You can save an indoor flower by replanting it in a new soil mixture and adding fertilizers containing iron.

Natural causes

Some lovers indoor plants they begin to panic, even if one or two leaves have fallen from the hibiscus, or they have turned a little yellow. This happens when the hibiscus is actively developing, it has many new leaves, and the old ones die off. There is nothing terrible in this process; natural changes occur in living nature.

Prevention of hibiscus diseases and preventive pest control measures (video)

Hibiscus, otherwise called Chinese rose, popular ornamental plant with beautiful bright flowers. At the moment, many varieties have been developed that take root well at home and grow well. Hibiscus, room care at home, which is produced according to all the rules, will delight the owners of the house with its flowering for a long time. So, what should care be like? indoor hibiscus at home?

It is not known for certain who was the first to decide to call the Chinese rose exactly that. Since ancient times, there have been various signs regarding plants. Some superstitions promise good luck, others are not so optimistic. So why is hibiscus called the flower of death? However, this is not the only plant that is on such an unlucky list; in addition to the Chinese rose, ivy, calla lilies are considered deadly, and according to legend, all these plants bring death to the house.

There are different signs about hibiscus. If the plant unexpectedly blooms, this is a sign of the imminent death of one of the household members. Dropping leaves promises serious illnesses and troubles. Probably, once upon a time such coincidences actually happened, because of which the flower acquired notoriety. However, in Soviet and current years, this is a very popular plant in city apartments, behind which no sinister manifestations have been observed.
Is it possible to keep hibiscus at home? Absolutely yes. The flowers, leaves and fruits of hibiscus are not poisonous, which means that superstitions have no convincing basis.

Optimal temperature conditions

How to care for hibiscus? The Chinese rose loves warmth, so for its comfortable existence it is necessary to maintain a temperature of no lower than 18 and no higher than 22 degrees Celsius. However, hibiscus blooms in the cool season at +15º C. Therefore, after the summer months, it is better to take the flower to a cooler place without bright sunlight. In summer, a pot with a plant can be kept on the veranda in the garden or on the balcony of a city apartment. Chinese rose loves fresh air, but it should be protected from drafts.

Which lighting to choose

Hibiscus loves not only warmth, but also bright sun. For this reason, it should be kept in southern rooms. If it is too hot, the plant should be removed from the windowsill away from the glass or covered to protect it from the sun. Alternatively, the flowers can be placed on a table by the window, where there is enough light, but the sun's rays are not so aggressive and will not damage the delicate hibiscus petals.

Lack of light is one of the reasons why hibiscus leaves turn yellow and fall off, and in some cases, buds. What to do in such a situation? It is enough to provide the plant with access to good lighting.

How to water

Hibiscus requires timely watering, in addition to constant spraying. Without enough moisture, it can dry out. You only need to water the flower with water. room temperature, before watering, the water should settle in glass containers with a wide neck. If the apartment is too hot, moisture will quickly evaporate from the ground. To prevent this from happening, you need to use devices to reduce evaporation or cover the soil with regular moss.

To keep the leaves green and healthy, they need to be sprayed regularly and the air in the room must be kept sufficiently humid. To do this, you can use humidifiers or simply place containers of water on the batteries. When spraying the leaves, do not touch the flowers; they must remain dry. Periodically, the plant needs to be washed in the bathroom, washing away dust and dirt from the leaves. To prevent water from leaking into the pot, cover it with a plastic bag.

If the leaves turn black, this is a sign of excess water. To save the plant, you need to remove it along with the earthen lump from the pot and put it to dry for 12 hours. Then you should cut off the rotten roots and replant the flower in fresh soil.

Difficulties in growing hibiscus

Hibiscus is enough unpretentious plant, so even if you make a mistake somewhere while leaving, it can be quickly corrected. Those who have only recently purchased a Chinese rose often wonder why the hibiscus leaves turn yellow and begin to dry out or fall off. This problem can be easily corrected by spraying more frequently as soon as you notice that the leaves have become limp. In addition, the plant itself sheds its leaves after flowering - this is completely normal.

If the flower is dry, it may be a sign that the ground is too cold. Hypothermia can also cause leaves to turn black. The plant must be returned to a warm place and do not forget about abundant watering. If everything is done on time, the hibiscus can still be revived.

Why do hibiscus leaves turn yellow and fall off? This problem may indicate poorly filtered water. If the leaves are not only yellow, but also have browned edges, this means that there is little nitrogen in the soil. When temperature and humidity change sharply, the stressed plant sheds both leaves and buds. However, then it recovers and grows new leaves.

How to plant Angel Wings

Pests and diseases

Chinese hibiscus, like any other indoor plant, faces various diseases and pests. If you care for hibiscus at home in a timely manner, it will help you avoid trouble. However, even with good care, mites, aphids or some diseases may appear, which can become a headache for novice gardeners.

Spider mites

All dried flowers and leaves must be removed in time. If preventive measures turned out to be ineffective, to get rid of the tick, more frequent watering and spraying is needed. In this case, the plant pot must be completely covered with polyethylene so that the moisture does not evaporate. Spider mites die in conditions that are too wet.

Aphid

In small quantities, aphids are not dangerous, but if there are too many of them, the leaves will begin to turn yellow, curl up and sooner or later fall off. The plant itself will look sluggish and stop blooming. If there are too many aphids, sticky secretions of these insects will be visible on the leaves.
While there are few aphids, the leaves can simply be washed with soapy water. If the insects have already taken root on the Chinese rose, only spraying will help. by special means. After using chemicals, the plant will require more careful care until it is fully restored.

Leaf chlorosis

This disease is typical for hibiscus. Chlorosis occurs due to improper care behind the flower. Signs of the disease:

change in leaf shape;
the appearance of brown spots;
dry petals;
the buds do not bloom and fall off.

Chlorosis indicates a deficiency of useful microelements - manganese, potassium, zinc, etc. The plant can be saved by replanting it in fresh and well-fertilized soil. In addition, daily spraying is necessary. If the disease began recently, it is enough to simply fertilize the soil.

Indoor hibiscus is not difficult to care for, and therefore both experienced gardeners and beginners can grow beautiful flowers. Large bright flowers will decorate the room and will delight the eye for a long time. Such a flower can become not only an interior decoration, but also a good gift for loved ones or friends.

Preface

The Chinese rose, also known as hibiscus, is quite unpretentious, but it also has its enemies in the form of various pests and diseases that plague it. Knowing the causes of damage to any ailments, you can completely prevent this plant from becoming sick. And if a similar misfortune befell the Chinese rose, then you need to know about ways to combat it.

Most of the diseases of the Chinese rose are associated with improper care for it. And in second place in terms of the number of diseases and the frequency of their manifestation are cases of infection with fungi and pathogenic viruses. But, by the way, the defeat of a rose by most of these diseases also depends on the correctness of its cultivation. After all, when a plant does not receive proper care, it becomes weakened and, as a result, more susceptible to infection by fungi and viruses.

Chinese rose

Hibiscus is resistant to the vicissitudes of fate - it is not very dependent on how it is grown. This means that even serious flaws in caring for it cannot cause significant harm to the Chinese rose. However, this plant “forgives” such negligence only if it is allowed in a single quantity. Systematic violation of any requirements of agricultural technology will certainly provoke certain troubles and diseases. The hibiscus will first begin to feel unwell (weaken), and then it will wither and get sick.

Thus, all currently known diseases of the Chinese rose can affect it due to the following errors in care:

placing the plant in a draft, under the wind or direct rays of the sun;
excessive watering, resulting in root rot;
placement in a dry or hot room;
pollution and dustiness of the plant, especially its leaves;
lack of spraying or when it is extremely rare, especially in summer;
watering with water of poor quality (containing many harmful impurities or not settled);
poor lighting, and sometimes turning the flower with its back side facing the sun;
“overfeeding” with fertilizers;
lack of fertilizing and replanting;
allowing contact with already diseased plants, as a result of which the hibiscus is affected by diseases and pests.

All these violations in care, subject to their systematic impact on the Chinese rose, provoke various diseases in it. If this plant is provided with favorable conditions or at least not injured by careless treatment, then it grows for quite a long time and is sure to please with its flowering every year from April right up to October, or even longer.

The first signs of deterioration in health or illness of a Chinese rose in most cases are any changes in the condition of its leaves, as well as some other symptoms listed below. In each individual case, the plant may be unwell, usually for one of several reasons. Below are the main symptoms and the most likely causes that caused them.

Yellowed hibiscus leaves

If the hibiscus has leaves:

Yellowed - the plant is infected with pests (spider mites or aphids), its roots turn white, the leaves have chlorosis, or the air in the room is not humid enough.
They turn yellow and fall off - stress (occurs when unfavorable factors occur or a sharp change in living conditions), drafts or insufficiently humid air in the room, and in winter also from waterlogging of the roots.
They fall off - there is insufficiently humid air in the room, stress, sudden changes in light intensity or drafts.
They wither at the tips - the plant lacks phosphorus and nitrogen, and also, most likely, some other nutrients.
If they curl into a tube, they are infested with pests, most likely aphids.
They fall off along with the flower buds - the room is too hot, the plant lacks potassium, or it is affected by a pest (midge midge).
They wither along with the entire plant - the room is too hot or the humidity is below critical levels for the Chinese rose.

What exactly is the reason for the appearance of most of these symptoms must begin to be determined by identifying possible deficiencies in care. That is, we determine whether the temperature and humidity in the room, the frequency and amount of watering, as well as spraying and fertilizing with fertilizers correspond to those required for hibiscus. Then, using the method of elimination, we determine possible, and, most often, real reasons. If they consist of improper care, then we eliminate the mistakes made. How to deal with other reasons will be discussed later.

The most common hibiscus diseases are described below. Most of them manifest themselves in changes appearance leaves. Let's start with these ailments in order of their prevalence. Leaf diseases in the vast majority of cases are caused by chlorosis. This is a disease in which the process of chlorophyll formation in a plant is disrupted and the activity of photosynthesis is reduced. The main characteristic signs of this disease in hibiscus are yellowing and/or falling leaves. There are two types of chlorosis - non-infectious and infectious.

Non-infectious rose chlorosis

Most often, the Chinese rose is affected by non-infectious chlorosis. The reasons for its occurrence lie in nutritional disorders: insufficient or excessive supply of nitrogen, potassium, iron and magnesium. Moreover, it should be noted that magnesium and potassium are, by their nature, competing elements. That is, an excess of one causes a deficiency of the second. Symptoms of non-infectious chlorosis in Hibiscus are as follows. With a lack of iron, the leaves turn yellow and then fall off. If there is thinning of the branches, the plant does not bloom at the right time, or its flowers are pale in color (not bright enough), then this indicates a potassium deficiency. When a rose lacks magnesium or nitrogen, the leaves become covered with spots: yellow, whitish or lemon-colored.

Infectious chlorosis, as its name suggests, affects hibiscus due to infection. The causative agents of this are fungal microorganisms, viruses and even pests. Symptoms of infectious chlorosis are as follows: yellowing and subsequent falling of leaves, as well as general weakness and lack of flowering of the plant. Perhaps the next most common disease is sunburn. Signs of this disease are the appearance of white spots on the leaves, as in the photo. They arise as a result of partial destruction of green tissues by chloroform under direct sunlight. This usually happens with plants for which the lighting intensity has suddenly changed - they have been moved from a less lit place or from a greenhouse to bright sun.

Vascular wilt is the result of infection of hibiscus by fungi of the genus Verticillium or Fusarium. With verticillium, the leaves of the plant begin to curl and turn yellow at the bottom of the trunk. This process then moves up the stem. A severely affected rose will only have the very top remaining green. If the room is hot, the leaves wither very quickly, without having time to curl, causing the plant to look as if it had been scalded. Fusarium disease manifests itself in the slow wilting and subsequent death of leaves without changing their color, that is, they remain green. The edges of the upper leaves may become watery, and some areas may become pale green or light yellow. In both cases, after all the leaves are damaged, the trunk quickly dries out and the plant dies.

Bacterial spot

Bacterial spotting is a disease, the manifestations of which can be observed not only on the leaves, but also on the shoots. Basically, this disease in Hibiscus is caused by bacteria of the same type as Xanthomonas. This disease most often affects young shoots and leaves. Depending on the specific type of pathogen, the symptoms of the disease may differ slightly. The most characteristic and common picture is when watery yellow small spots first appear on the stems and leaves (visible in the photograph), which gradually turn black. The shape of the spots is most often irregularly angular, and a light green or yellow border is visible along their contour. The spots gradually increase in size and then merge. As a result, the entire sheet turns black. This way the disease progresses throughout the entire plant and eventually it dies.

Another variant of spotting caused by bacteria is fire blight. Its causative agent is other bacteria belonging to the genus Pseudomonas. Most often, bacterial burn begins with young shoots, leaves and flowers. Its symptoms are as follows. Not spots form on the plant, but rather large, shapeless areas of blackening (as in the photo), which soon dry out. Outwardly, such areas on the sheet look as if it was burnt in this place. Progression bacterial burn first causes the death of individual parts of the plant, and then its death. At favorable conditions this disease develops very quickly.

When affected by brown rot, hibiscus stems turn brown and thin at the very base. The rose is greatly weakened and may die. Most often, this disease affects young seedlings and plants.

Most of the problems that arise with hibiscus can be solved by normalizing the conditions of its maintenance and eliminating errors in care. Since the purpose of this article is not to consider exactly how to care for a Chinese rose, all these points will be omitted. We will only focus on eliminating a number of specific omissions in care, indicated above in the chapter on the main symptoms of deterioration in the plant’s condition. If there is insufficient humidity in the room, the plant must be sprayed more often - not once, but several times a day. At the same time, the soil should not be allowed to become waterlogged - so that after such a “shower” there will be water standing in the pot. If the Hibiscus is hot, then you should try to lower the temperature in the room with it, and you should also shade it and spray it.

Fertilizers for Chinese rose

When a plant lacks some nutrients, then, of course, it is necessary to feed it with appropriate preparations that include exactly the missing elements. If the roots become waterlogged in winter, then watering should be temporarily reduced in quantity and volume, and the plant itself should be sprayed instead, making sure, again, that less water gets into the soil and that it does not turn into a liquid mush. What to do in case of drafts is clear - you need to eliminate the cause of their occurrence or move the Chinese rose to another, quieter place.

Now about the treatment of diseases. Non-infectious chlorosis can not only be defeated, but also prevented by regularly feeding Hibiscus with fertilizers. If, however, this misfortune does occur, the emphasis should be placed precisely on those supplements that contain the missing elements. It should also be noted that symptoms of iron deficiency (yellowing of leaves) appear against the background of a lack of nitrogen and an increased content of chlorine and calcium in the water used for irrigation. Therefore, before watering, the water must be settled, and then a microfertilizer such as iron chelate must be added to it. The latter should be done if there really is an iron deficiency. And you need to ensure that the amount of fertilizing containing nitrogen is sufficient.

Infectious chlorosis is best prevented. To do this, the Chinese rose should not be allowed to come into contact with diseased plants; it must be replanted and fertilized in a timely manner, and it must also be regularly cleaned of dust and dirt. The latter is best done while washing the hibiscus in the shower. The soil in the pot must be covered with cellophane. And yet, all new plants brought home must undergo a temporary quarantine procedure. That is, for several weeks they need to be placed separately and away from existing flowers. In case of hibiscus disease, use appropriate medications (intended to combat identified diseases and pests) to treat it.

To prevent sunburn, Chinese roses grown in greenhouses and in a darkened room must be accustomed to changing lighting gradually, first exposing them to the sun for an hour and a half a day. Then we gradually increase the duration of the plants’ exposure to bright light and only after complete adaptation to it do we change their “place of residence.” If the hibiscus does get burns, it’s okay. It quickly gets used to the change in lighting, and the leaves that have received burnt spots simply fall off, giving way to new normal ones that soon grow.

Zircon for processing roses

Vascular wilt is very difficult to treat and it is not always possible to cure hibiscus from it. Often it dies quickly and it happens that its leaves do not even have time to fall. This disease should be dealt with as follows:

We cut off all the affected (dried) fragments of the plant, while slightly capturing its healthy parts.
We treat the entire rose with special antifungal compounds: Fundazol, Topsin, Dezavid, Alirin-R or others. You can also use the drug Rovral, the solution of which must be poured under the root. There is also a folk remedy - spraying the plant with a solution Trichopolum(2 tablets per 1 liter of water).
Additionally, you can stimulate the rose’s defense mechanisms by treating it with drugs Epin, Zircon, Domotsvet. You just need to make sure before that that the chosen composition can be used in combination with the antifungal agent used.

If vascular wilt cannot be cured at the initial stage, and the hibiscus continues to hurt and wither, it will have to be destroyed. Bacterial spotting can be remarkably cured by spraying the plant itself while simultaneously watering the soil in the pot with a solution Trichopolum(1 tablet for 2 liters of water). Also effective are such well-known copper-containing preparations as copper sulfate and Bordeaux mixture. It can also be used not only for treatment, but also for prevention. Fundazol, Euparen. To prevent brown rot, hibiscus cuttings and seedlings should be treated with Rovral. In addition, seedlings should be planted shallowly, and after planting they should be thoroughly sprayed with the same preparation.

When a plant is stressed, you must first try to figure out what caused it. If the reason is a significant deviation in the conditions of maintenance from those necessary for hibiscus, then it must be eliminated. The plant is unlikely to adapt to this, especially if the changes that have occurred are, in principle, unacceptable for its life. Stress can also occur due to the fact that the rose is greatly disturbed, for example, they often change its “place of residence” (they constantly replant it or move it from one place to another, which usually happens during renovations and moves) or do not monitor the behavior of children and pets who show excessive curiosity about indoor plants.

Signs of Stress in Hibiscus

Such effects on the plant must also be stopped immediately. In the first case, the hibiscus should be left alone, at least for a while, until it copes with stress (stop replanting or choose the most suitable one for it). appropriate place, from which it will not need to be transferred for a relatively long time). In the second - to forever protect the plant from domestic “robbers”, that is, for example, find a place for it that is inaccessible to them.

Stress can also be caused by minor changes in living conditions, when their main parameters are within acceptable values (associated with: transfer from one room to another or from a greenhouse to permanent place a habitat; with slight deviations from previous care), seasonal changes in environment(for example, reducing the level and duration of lighting in winter), any damage, replanting or flowering (also a stressful load for young and weakened plants). In this case, no drastic measures will have to be taken.

Well, the Chinese rose, as a rule, is able to cope with stress itself. In the first two cases, this will happen after eliminating the causes that provoked it, and in the last - due to adaptation to new conditions. But in order for the plant to successfully and quickly cope with stress, it is necessary to provide it with rest, spray it more often and more carefully monitor compliance with the schedule and norms of watering and fertilizing, as well as the quality of the water and fertilizers used for this.

In addition, hibiscus can be helped to stimulate adaptive processes in it with the help of anti-stress drugs, especially if the stressful state does not go away for a long time and the plant is severely weakened. These include: Zircon, Fitosporin, Planriz, Epin-Extra, Planriz, Krezacin. Such drugs have an immunostimulating and anti-stress effect on plants. You must select and use the desired “drug” in accordance with the instructions for it.

The most common pests and their control

Pests appear on a plant in two cases: when they are transplanted into contaminated soil or as a result of contact with already diseased flowers. Hibiscus is most often affected by the following pests.

Aphid. This small insect settles primarily on young leaves and shoots, as well as on the buds of the plant. It multiplies very quickly, creating entire colonies. It is capable of completely destroying unopened flowers and young leaves, which at the initial stage of infection become sticky and deformed. To combat aphids it is necessary to treat the plant with drugs. Akarin, Fitoverm, Biotlin, Intra-Vir, Decis. They also help a lot Nicotine sulfate And Tobacco dust. In the early stages and in cases of single partial damage to leaves, it is enough to limit treatment with a regular soap solution.

Spider mite. You won’t be able to see this pest without a magnifying glass, especially since it settles at the bottom of the leaves. When attacked by a tick, the latter first become dull and become covered with small yellow specks, which is clearly visible in the photograph. The pest envelops the underside of the leaves with a dense web, in which it lives. Subsequently, if measures are not taken immediately, extensive dried areas will form on the leaves. The fight against mites includes washing the leaves with soapy water or mineral oil and then treating the plant with medications. Akarin, Lightning, Vertimek, Fitoverm.

Whiteflies. They usually hide on the underside of the leaves, where their adults and pale larvae can be found. yellow color(shown in the photo). A characteristic sign of a plant being affected by whitefly is the appearance of a shiny sticky coating on the upper side of the leaves. This is the excretions of the pest. After some time, sooty fungi develop in them, due to which the surface of the leaves becomes first white and then black. It is these mushrooms that can cause severe harm to the plant, and not the whiteflies themselves. In addition, this pest is a carrier of various viral infections. Symptoms of whitefly-borne diseases can vary widely. This is chlorosis, and the leaves can turn yellow, become deformed, and curl.

This pest must be combated by treating the plant with a solution of potassium soap or with the preparations Aktara, Admiral, Biotlin, Bankol, Iskra, Apploud, Fufanon, Tanrek.

Scaleworms. Signs of damage to the plant by them: waxy lumps and powdery coating appear in the axils of the leaves and on the cuttings white, as in the photograph. Methods of control: treatment with the same drugs as for whiteflies.

Scale insects and false scale insects. Signs of damage: pale brown or brownish round scales (tubercles) appear on the stems and leaves of the rose, which can be difficult to separate from the plant. These are already adult pests. If the damage is not severe, clean off the scales with a cloth or toothbrush dipped in a soap or alcohol solution. Kerosene-soap emulsion also works well. In case of severe damage, we use one of the above insecticides.

Midge gall midge. Signs of damage: leaves and more unopened buds turn yellow and fall off. It is imperative to inspect the buds and identify any affected ones. They will be visible small eggs pest All these and yellowed buds must be torn off. They should not be allowed to fall on the ground. Then we treat the soil with one of the above insecticides.

Chinese rose

Thus, all currently known diseases of the Chinese rose can affect it due to the following errors in care:

placing the plant in a draft, under the wind or direct rays of the sun;
excessive watering, resulting in root rot;
placement in a dry or hot room;
pollution and dustiness of the plant, especially its leaves;
lack of spraying or when it is extremely rare, especially in summer;
watering with water of poor quality (containing many harmful impurities or not settled);
poor lighting, and sometimes turning the flower with its back side facing the sun;
“overfeeding” with fertilizers;
lack of fertilizing and replanting;
allowing contact with already diseased plants, as a result of which the hibiscus is affected by diseases and pests.

Yellowed hibiscus leaves

If the hibiscus has leaves:

Yellowed - the plant is infected with pests (spider mites or aphids), its roots turn white, the leaves have chlorosis, or the air in the room is not humid enough.
They turn yellow and fall off - stress (occurs when unfavorable factors occur or a sharp change in living conditions), drafts or insufficiently humid air in the room, and in winter also from waterlogging of the roots.
They fall off - there is insufficiently humid air in the room, stress, sudden changes in light intensity or drafts.
They wither at the tips - the plant lacks phosphorus and nitrogen, and also, most likely, some other nutrients.
If they curl into a tube, they are infested with pests, most likely aphids.
They fall off along with the flower buds - the room is too hot, the plant lacks potassium, or it is affected by a pest (midge midge).
They wither along with the entire plant - the room is too hot or the humidity is below critical levels for the Chinese rose.

The most common hibiscus diseases are described below. Most of them manifest themselves in changes in the appearance of leaves. Let's start with these ailments in order of their prevalence. Leaf diseases in the vast majority of cases are caused by chlorosis. This is a disease in which the process of chlorophyll formation in a plant is disrupted and the activity of photosynthesis is reduced. The main characteristic signs of this disease in hibiscus are yellowing and/or falling leaves. There are two types of chlorosis - non-infectious and infectious.

Non-infectious rose chlorosis

Bacterial spot

Another variant of spotting caused by bacteria is fire blight. Its causative agent is other bacteria belonging to the genus Pseudomonas. Most often, bacterial burn begins with young shoots, leaves and flowers. Its symptoms are as follows. Not spots form on the plant, but rather large, shapeless areas of blackening (as in the photo), which soon dry out. Outwardly, such areas on the sheet look as if it was burnt in this place. The progression of bacterial burn first causes the death of individual parts of the plant, and then its death. Under favorable conditions, this disease develops very quickly.

When affected by brown rot, hibiscus stems turn brown and thin at the very base. The rose is greatly weakened and may die. Most often, this disease affects young seedlings and plants.

Fertilizers for Chinese rose

Zircon for processing roses

We cut off all the affected (dried) fragments of the plant, while slightly capturing its healthy parts.
We treat the entire rose with special antifungal compounds: Fundazol, Topsin, Dezavid, Alirin-R or others. You can also use the drug Rovral, the solution of which must be poured under the root. There is also a folk remedy - spraying the plant with a solution Trichopolum(2 tablets per 1 liter of water).
Additionally, you can stimulate the rose’s defense mechanisms by treating it with drugs Epin, Zircon, Domotsvet. You just need to make sure before that that the chosen composition can be used in combination with the antifungal agent used.

If vascular wilt cannot be cured at the initial stage, and the hibiscus continues to hurt and wither, it will have to be destroyed. Bacterial spotting can be remarkably cured by spraying the plant itself while simultaneously watering the soil in the pot with a solution Trichopolum(1 tablet for 2 liters of water). Well-known copper-containing preparations such as copper sulfate and Bordeaux mixture are also effective. It can also be used not only for treatment, but also for prevention. Fundazol, Euparen. To prevent brown rot, hibiscus cuttings and seedlings should be treated with Rovral. In addition, seedlings should be planted shallowly, and after planting they should be thoroughly sprayed with the same preparation.

Signs of Stress in Hibiscus

Such effects on the plant must also be stopped immediately. In the first case, the hibiscus should be left alone, at least for a while, until it copes with stress (stop replanting or choose the most suitable place for it, from which it will not need to be moved for a relatively long time). In the second - to forever protect the plant from domestic “robbers”, that is, for example, find a place for it that is inaccessible to them.

Stress can also be caused by minor changes in living conditions, when their main parameters are within acceptable values (associated with: transfer from one room to another or from a greenhouse to a permanent habitat; with slight deviations from previous care), seasonal changes in the environment environment (for example, reducing the level and duration of lighting in winter), any damage, replanting or flowering (also a stress load for young and weakened plants). In this case, no drastic measures will have to be taken.

Signs of a spider mite

Whiteflies. They usually hide on the underside of leaves, where their adults and pale yellow larvae (shown in the photo) can be found. A characteristic sign of a plant being affected by whitefly is the appearance of a shiny sticky coating on the upper side of the leaves. This is the excretions of the pest. After some time, sooty fungi develop in them, due to which the surface of the leaves becomes first white and then black. It is these mushrooms that can cause severe harm to the plant, and not the whiteflies themselves. In addition, this pest is a carrier of various viral infections. Symptoms of whitefly-borne diseases can vary widely. This is chlorosis, and the leaves can turn yellow, become deformed, and curl.

This pest must be combated by treating the plant with a solution of potassium soap or with the preparations Aktara, Admiral, Biotlin, Bankol, Iskra, Apploud, Fufanon, Tanrek.

Scaleworms. Signs of damage to the plant by them: waxy lumps and a white powdery coating appear in the axils of the leaves and on the cuttings, as in the photograph. Methods of control: treatment with the same drugs as for whiteflies.

Midge gall midge. Signs of damage: leaves and unopened buds turn yellow and fall off. It is imperative to inspect the buds and identify any affected ones. Small eggs of the pest will be visible in them. All these and yellowed buds must be torn off. They should not be allowed to fall on the ground. Then we treat the soil with one of the above insecticides.

Hibiscus, which many lovers of indoor flowers keep in their homes, is very pleasant and beautiful to look at. However, this plant, like any other, can suffer from diseases caused by pests, fungi or viruses, or improper care. The article will briefly describe the most common hibiscus diseases and their treatment at home.

Basic mistakes in plant care

Hibiscus, also known as Chinese rose, is not a very capricious plant, and it is quite unpretentious in care. It forgives small mistakes, but systematic violations of temperature and water conditions and other parameters it needs, naturally, will not go in vain. The plant will begin to hurt, wither, and if nothing changes, it may even die.

To the most frequent mistakes Hibiscus care includes:

Violation of the watering regime, which can lead to rotting of the roots of the flower.
Watering the plant with contaminated or hard water that has not had time to settle properly.
Lack of spraying necessary for the flower, especially in the hot season.
Hot and dry indoor climate.
Leaves exposed to direct sunlight.
Bad light.
Drafts in the room.
Untimely transplant
Incorrect feeding - lack of nutrients or “overfeeding”.
Dust and dirt on the plant.

Long-term violation of the requirements for caring for Chinese roses will certainly cause the development of diseases of home hibiscus.

Diseases caused by improper care: sunburn

Yellow spots on the leaves may be the result of sunburn. When choosing a place for a plant, you need to remember this. Usually, the Chinese rose tolerates sunlight well, but if you place a flower accustomed to shade in the bright sun, hibiscus leaf disease cannot be avoided. Dry yellow spots appear on them. They can also occur in places that are pressed against the glass. To avoid this, experts recommend accustoming hibiscus to sunlight gradually. Affected leaves with dry areas will have to be removed.

It is also necessary to know that changes in the color of leaves and the appearance of spots on them may be associated with a lack of certain substances in the soil. For example, if there is a lack of an element such as zinc, the leaves may become speckled and shredded. If the edges turn brown, the plant does not have enough sulfur. Marbling of the leaves, in which there are white spots between the veins, indicates a lack of magnesium. If the hibiscus lacks potassium, the leaves may begin to die at the edges. In addition, the plant will not bloom well.

Leaf chlorosis

Leaf spotting, or chlorosis, can also be caused by a lack of nitrogen and magnesium, and their yellowing and falling off can also be caused by a lack of iron in the soil. This is the so-called non-infectious chlorosis. The problem is solved by applying fertilizers, which should be regular, from spring until about mid-August, once every two to three weeks, and then, until the dormant period, once a month.

The lack of iron can be compensated for by adding iron chelate (5 g per 5 liters of water) to the water for irrigation. It is recommended to spray the leaves with the same solution. In total, it is advisable to carry out at least four treatments (once every two weeks).

This hibiscus disease (photo can be seen below) can also be caused by pathogens - viruses, fungi, bacteria, which are often carried by pests.

In this case, the plant usually has a depressed appearance. It is quite difficult to cure chlorosis in this case, since it is difficult to determine the causative agent of the disease. Therefore, it is easier to prevent it: provide good care, regularly wipe the leaves from dust and dirt, spray the hibiscus, replant it in a timely manner, changing the soil to a new one.

Vascular wilt of hibiscus

It is impossible not to mention tracheomycosis when describing hibiscus diseases. This disease is quite dangerous and difficult to treat. It is caused by mushrooms. In this case, the branches first die off at the base, then the trunk is gradually affected and the plant dies. How to save hibiscus? First of all, it is necessary to cut off all the affected areas, including a little healthy tissue. After this, the plant is treated with one of effective fungicides, for example, "Fundazol".

Diseases caused by pests: aphid damage

When describing diseases and pests of hibiscus, it is necessary to mention the damage to the plant by aphids. The leaves of the plant become deformed and become sticky. To get rid of insects, you need to manually treat them with soapy water using a cotton swab, making sure that it does not get into the soil if possible. After this, the hibiscus is sprayed with Aktara solution. The treatment must be repeated at least once - every two weeks.

Spider mite infestation

This is one of the main pests of hibiscus. When it infects the leaves, it envelops them from below with a web. The leaves curl and wither. This pest thrives in dry, warm conditions, so in order to prevent infection, it is necessary to keep the hibiscus leaves clean and spray them regularly.

They will help fight the pest chemicals, such as “Aktellik”, “Fitoverm”, “Neoron”. However, the peculiarity of this pest is that it quickly gets used to such drugs. Oddly enough, folk remedies may be more effective. Most often, soapy water, infusion of garlic, and onion peels are used. To prepare the infusion, two heads of garlic are crushed and filled with water (1 liter). Leave in a dark place for five days. Before use, the product is diluted in half with water and used to spray the plant.

For onion infusion, 100 grams of onion peel must be poured with five liters of water and infused for four to five days. Strain the infusion and use to spray hibiscus.

It is advisable to periodically wipe the window sill on which the plant stands with a soap solution as a preventative measure.

Whitefly infestation

This small flying insect should also be mentioned when describing ficus diseases and their treatment (a photo of the pest is presented below). It lives with reverse side hibiscus leaves. The leaves become covered with sticky spots and turn yellow.

To get rid of whiteflies, they usually use chemicals- “Fufanon”, “Aktaru”, “Iskra”. Adult insects can be washed off with a stream of water, and larvae, eggs and plaque can be removed with a swab of soapy water (100 g of crushed laundry soap, or better yet, tar soap per half liter of water).

Why doesn't hibiscus bloom?

The lack of flowering in hibiscus can be called a disease at a stretch, but it can ruin a gardener’s mood for a long time. What could cause it?

The first reason is shortage useful substances(particularly potassium deficiency). The plant simply does not have enough resources to flower. The second is lack of lighting. Bright light is necessary for setting buds. In order for hibiscus to bloom, the time spent in light must be at least four hours a day. The lack of flowers may be due to the fact that pruning was not carried out in a timely manner. It must be remembered that flowers form on young shoots. To plant them, it will also be useful to replace the soil in the pot and carefully move the hibiscus to a more illuminated place.

In addition, the flower needs a rest period from October to February. It is believed that in order for the Chinese rose to bloom, it is necessary to reduce the room temperature to 15-18 degrees Celsius. Flower buds are formed precisely under these conditions. Although cases of winter flowering of hibiscus are not uncommon. If the sun's rays penetrate well into the room, this is quite possible.

In addition, the hibiscus may begin to prepare for flowering and suddenly drop its buds. Why is this happening? Experts note that during the flowering period, the Chinese rose should under no circumstances be moved from place to place. Hibiscus generally does not tolerate rearrangements very well, and even more so during flowering or preparation for it, when all the flower’s forces are spent on forming buds.

Describing hibiscus diseases and their treatment (photos of some of them are presented in the article), it should be noted that the fall of the flower ovary can also be a consequence of damage to the hibiscus by a pest - gall midge, a miniature midge. She attacks the buds, laying her eggs in them. Naturally, the hibiscus will no longer bloom, the plant will shed its buds. If it is clear that they have turned yellow, they must be carefully torn off and destroyed to prevent the spread of pests. The soil should be treated with Provotox, Grizzly or Fly Eater, strictly following the instructions.

So, to summarize, we can say that for a plant to bloom, a period of rest in winter, pruning, optimal lighting and timely feeding. In addition, you should not often move the flower from place to place.

Finally

As you can see, diseases of indoor hibiscus are quite diverse and can affect all parts of the plant. Similar symptoms can be caused either by violation of the rules of plant care or by pest damage. To successfully treat hibiscus diseases (photos of some of them were presented in the article), you need to know what conditions should be provided to the flower, what drugs and in what dosage to use to rid it of pests, etc. This knowledge is the key successful cultivation plants at home.

Hibiscus, otherwise known as Chinese rose, is a popular ornamental plant with beautiful, colorful flowers. At the moment, many varieties have been developed that take root well at home and grow well. Hibiscus, which is cared for indoors at home according to all the rules, will delight the owners of the house with its flowering for a long time. So, what should be the care for indoor hibiscus at home?

There are different signs about hibiscus. If the plant unexpectedly blooms, this is a sign of the imminent death of one of the household members. Dropping leaves promises serious illness and misfortune. Probably, once upon a time such coincidences actually happened, because of which the flower acquired notoriety. However, in Soviet and current years, this is a very popular plant in city apartments, behind which no sinister manifestations have been observed.
Is it possible to keep hibiscus at home? Absolutely yes. The flowers, leaves and fruits of hibiscus are not poisonous, which means that superstitions have no convincing basis.

Optimal temperature conditions

Which lighting to choose

How to water

Hibiscus requires timely watering, in addition to constant spraying. Without enough moisture, it can dry out. Water the flower only with water at room temperature; before watering, the water should sit in a glass container with a wide neck. If the apartment is too hot, moisture will quickly evaporate from the ground. To prevent this from happening, you need to use devices to reduce evaporation or cover the soil with regular moss.

Difficulties in growing hibiscus

Hibiscus is a fairly unpretentious plant, so even if you make a mistake somewhere when caring, it can be quickly corrected. Those who have only recently purchased a Chinese rose often wonder why the hibiscus leaves turn yellow and begin to dry out or fall off. This problem can be easily corrected by spraying more frequently as soon as you notice that the leaves have become limp. In addition, the plant itself sheds its leaves after flowering - this is completely normal.

How to plant Angel Wings

Pests and diseases

Chinese hibiscus, like any other indoor plant, faces various diseases and pests. If you care for hibiscus at home in a timely manner, it will help you avoid trouble. However, even with good care, mites, aphids or certain diseases may appear, which can become a headache for novice gardeners.
