Why does hibiscus shed its leaves? What to do? Chinese rose (hibiscus) sheds its leaves like trees in autumn, what to do in such cases

Many plants that came to us from

other countries, are firmly entrenched in apartments and on personal plots amateur gardeners. And one of these fairly common crops is Hibiscus. The tropics are considered to be its homeland - India, China and Asia, but now such a variety of this plant as the Chinese rose is grown at home throughout Russia. Most often, this culture does not require any special attention, being quite unpretentious. However, in certain cases, the leaves of the flower begin to turn yellow and fall off. What could cause such a nuisance? Why do hibiscus leaves turn yellow and fall off? What to do about this? What is the best way to deal with trouble?

Of course, without sufficient information about the growing conditions of hibiscus, it is impossible to unambiguously and accurately determine the reasons for the yellowing of its leaves. However, there are certain factors that most often provoke such a problem.

If the hibiscus grows at a sufficiently high temperature, it needs systematic watering with a significant amount of water. If the plant is hot, then watering can be done twice a day. Those plants that are outdoors respond well to use. special devices for automatic drip irrigation.

If the leaves begin to turn yellow and fall off during the cold season, it may well be that such a nuisance was a consequence of excess moisture in the soil. As we have already said, the Chinese rose loves water very much, but it cannot thrive in a cold swamp in the area of ​​the root system.

If it is very hot outside or in the house, hibiscus can actively shed leaves, which turn yellow before this. You can cope with such a nuisance with the help of active watering, which will provide the crop with a sufficient amount of liquid.

Do not forget that the Chinese rose came to us from the tropics, and accordingly, it loves warmth very much. To make the flower feel comfortable, the temperature environment should fluctuate between eighteen and thirty degrees. Otherwise, its appearance will suffer and it may develop various diseases. For example, if you place a flower pot next to winter window, it can react to such a cold snap by quickly dropping its leaves.

Normal access to sunlight is a real source of life for the Sudanese rose. When there is a lack of light, the plant can actively shed its leaves, thus trying to reduce its need for light. This process can continue until just a couple of leaves remain on the hibiscus.

An infected bush has a diseased appearance and in some cases may become completely bare. Therefore, if signs of a spider mite are detected, you need to quickly take measures to save the plant. Therapy in this case is carried out using special compounds - insecticides, which you can easily buy in flower shop. But in fact, it is quite difficult to remove spider mites. Experts recommend carrying out preventive spraying of plants once a year to prevent such a problem from occurring.

Even slight air movements may not please the hibiscus and cause it to drop its leaves. Therefore, try to protect your plant from windy weather in the house.

There are several types of chlorosis. Yellowing of leaves can develop in different ways, depending on the severity of the disease. So if the leaf itself is green and turns yellow only in a limited place, we can conclude that the Chinese rose needs certain nutrients Oh. It may well be that your pet suffers from soil acidity problems or simply lacks nutrients. Nowadays, soil acidity is often disturbed due to watering tap water, which is characterized by increased rigidity.

This cause of yellowing of hibiscus leaves is the most rare, but nevertheless probable. If you apply pesticides during a particularly hot season or accidentally change the dosage, the hibiscus leaves may turn yellow and fall off. In addition, this problem can be caused by too frequent use of pesticides.

If you have identified the cause of the yellowing of hibiscus leaves and promptly eliminated it, the foliage will stop falling. The Chinese rose is capable of growing new green mass in a fairly short period of time. You can help your pet form a beautiful bush a little - trim branches that are too long or damaged. Pruning will activate the process of side shoots appearing, which will help the hibiscus become green and lush even faster.

Hibiscus, often called Chinese rose, can be found in the collection of almost any gardener. The thing is that this plant not only has amazing beauty, but is also famous for its unpretentiousness. Caring for hibiscus is not at all difficult, and even children can easily cope with this task. True, from time to time this charming flower still presents its owners with unpleasant surprises. Among them are yellowing and falling leaves, which in a few days can cover the entire windowsill with a soft carpet. There are several reasons why this happens.

Why do hibiscus leaves turn yellow?

In general, it is worth considering that from time to time this plant sheds its leaves, but in small quantities. However, if the process is systematic, then most likely your flower needs additional lighting. Hibiscus needs quite a lot of sun to feel comfortable. Therefore, it is best to place a flowerpot with a flower on a windowsill, covering the plant from direct sunlight in the summer with a curtain. This should not be done in autumn and winter. Moreover, in order for hibiscus to develop normally, its daylight hours must be at least 10 hours. Therefore, with the onset of cold weather, it is necessary to take care of additional artificial lighting, which will help to effectively solve the problem of yellowing leaves.

If they begin to change color at the base, then the source of the problems should be sought in the incorrect watering regime. Hibiscus, even in hot weather, consumes quite little water. Moreover, it feels much better if you moisten the leaves rather than the soil. Therefore, moderate watering 1-2 times a week with water room temperature is the best option when caring for this plant. Excessive soil moisture usually leads to the process of rotting of the root system. This is immediately reflected in the leaves, which begin to turn yellow and fall off. This process can only be stopped by replanting the hibiscus and limiting its watering. If this is not done, the flower risks dying within a few weeks. Before placing the plant in a new pot, you need to not only remove the yellowed leaves, but also cut off some of the rotten roots. In some cases, it is necessary to remove all of the hibiscus root system which turns out to be damaged. However, there is no need to worry about this, since within a few days after immersion in the soil, the flower will begin to form new roots. The main thing is not to water the plant for 5-7 days after transplantation, which will allow it to quickly adapt and recover. In about a month, when the hibiscus has fully grown, new lateral shoots with young leaves will begin to appear. If they have a rich green color, this means that you managed to save the plant.

For all its unpretentiousness, hibiscus has one serious drawback, which is the plant’s very sensitive response to any changes. external environment. Even if you simply rotate the flowerpot, changing the location of the plant in relation to the light source, this can cause stress in the flower, accompanied by leaf fall. Therefore, it is highly undesirable to move hibiscus without good reason. Also, drafts and temperature changes are strictly contraindicated for the plant, after which its leaves often begin to turn yellow and fall off. It is also worth paying attention to the air humidity in the room, which should be quite high. Dry and hot air usually causes hibiscus leaves to begin to turn yellow around the edges.. In such a situation, it is necessary to moisturize them several times a week using a spray bottle. In addition, you should ensure that the flowerpot with the flower is located at a considerable distance from heating devices, proximity to which can also lead to yellowing of hibiscus leaves. However, if the room is too cold, the flower will also shed its leaves. Therefore, the air temperature in the room where the hibiscus is located should not fall below +18 degrees even during winter. Another source of problems may be the infestation of hibiscus by mites, due to which characteristic signs appear on the leaves of the plant. yellow spots. In this case, the problem can be solved by treating the hibiscus with a soap solution or with special chemicals sold in flower shops.

Why does hibiscus (Chinese rose) turn yellow?

Yellowing hibiscus leaves- a signal to the owner that the plant is unhappy with something, that it is experiencing stress. It can be difficult to figure out what the cause of stress is, because hibiscus reacts to any cause in the same way - with yellowing and falling leaves. And, nevertheless, having information about probable reasons stress and after analyzing your case, you can most likely determine why your hibiscus is turning yellow.

1. Insufficient watering

During the hot season, hibiscus needs constant watering. The earthen ball should not dry out, and if to avoid this you need to water the hibiscus every day, water it. In addition, daily spraying of leaves in summer and weekly in winter is necessary, since the presence of heating devices in the room reduces the air humidity necessary for the plant. For both watering and spraying, use only settled water.

2. Overwatering

During the cool season, make sure that the soil in the pot does not turn into a runny mess. Hibiscus loves water, but does not tolerate cold swamps in the root area.

3. Abundant sunshine

Direct sunlight can cause not only yellowing of the leaves, but also the appearance of burns on them, so let the plant receive its normal dose of harmless morning rays, but it is better to shade it from the scorching midday sun.

4. Lack of light

Hibiscus, like any plant, produces chlorophyll only in the light. If there is not enough light, it will turn yellow and drop its leaves until a few leaves remain, which will only need the meager amount of chlorophyll produced by the plant in low light.

5. Temperature too low or too high

Chinese rose is a tropical plant, so it does not tolerate hypothermia. And overheating is not good for her. The temperature that is comfortable for her is +18+30. When it is cold or hot, it reacts by dropping yellowed leaves.

6. Pests

Hibiscus at home suffers greatly from spider mites. If you find traces of their activity on your plant (dirty spots on withered leaves, thin cobwebs between the leaves), take a magnifying glass and take a closer look: small mites look like crabs. Getting rid of them is not easy, so do not delay treating the plant with insecticides or spray it with soapy water several times a day. Restoring a plant destroyed by mites will take a very, very long time.

7. Soil chlorosis

The soil in which hibiscus grows can sometimes become too acidic or too alkaline. This usually occurs from watering the plant with unsettled hard tap water. In such cases, the leaves do not turn yellow completely, but in patches. Sometimes the yellowing of leaves is caused by a lack or excess of certain nutrients in the soil. In such cases, make necessary fertilizers or correct soil acidity.

8. Fertilizers

With frequent use of pesticides, the leaves also turn yellow, so try to treat the plant with the same pesticide in the same (minimal) consistency in the early morning or evening. Phosphate fertilizers added to irrigation water increase the flowering of hibiscus. But do not use high-phosphate fertilizers when caring for hibiscus: this kills the plant. When feeding the plant with nitrogen fertilizers, show a sense of proportion. As soon as you notice that the leaves brown edges, know that this is a nitrogen burn, which means you need to stop adding nitrogen fertilizers to the water for irrigation for two weeks. When you start fertilizing again, reduce the dose by half and increase it gradually, observing the leaves until you establish the optimal dose.

We looked at all the reasons why hibiscus turns yellow. All you have to do is discover yours through observation and experimentation. If you are not mistaken and manage to save the plant, you will be able to enjoy its thick foliage and lush flowering for a long time.

Hibiscus, also known as Chinese rose ( Hibiscus rosa-sinensis), can be considered one of the most luxurious and sophisticated indoor plants. Its large, bright flowers, contrasting with the green glossy foliage, invariably attract the attention of both amateur and professional gardeners.

Unfortunately, this luxurious handsome man sometimes begins to “be capricious,” upsetting his owners with deterioration. appearance, yellowing and falling leaves. The causes of this phenomenon can be various diseases, the destructive effects of pests, the plant’s reaction to stress, etc. And it is advisable for the gardener to know at least the main factors influencing the change in leaf color in order to be able to take timely measures and prevent the development of a process that could lead to the death of the green pet. Let's look at the most common of them.

1. Violation of the watering regime

An adult hibiscus, with a well-developed root system, consumes and evaporates a large amount of moisture, and therefore needs regular, abundant watering. The watering regime should be selected in such a way that the soil in the pot always remains slightly moist. But it is extremely undesirable to overdo it here. If you water the plant “in reserve,” the soil will quickly begin to become waterlogged and become too dense for normal functioning roots, and they will no longer cope with the work assigned to them. In addition, in soil oversaturated with stagnant water, various putrefactive processes actively develop, which negatively affect the root system and trunk of the plant and can lead to its death. The gradual death of the root system, the lack of nutrients that the roots can no longer supply to the plant in full, lead to the fact that the hibiscus begins to get rid of “excess” green mass, as a result of which the leaves first turn yellow and then fall off. If the development of the process is not stopped in time, the plant may die.

If the hibiscus is still small and has not grown into a large bush, then the first steps to save it are to remove it from the pot, remove the rotten, blackened roots, treat the remaining root system with fungicidal preparations and replant the plant in new soil. When replanting, the roots can be additionally powdered with “Kornevin”, and the crown of the plant can be sprayed with “Epin”. These measures should help reduce the plant’s stress from all procedures and quickly take root in its new location.

For an adult plant, the rescue procedure described above is of little use. Fortunately, due to the love of water, it is quite difficult to fill it. Another case is more likely here - the danger of drying out the plant, to which the hibiscus will react by drooping and withering of the leaves, which will later turn yellow and fall off.

2. Incorrect illumination level

Pretty hibiscus shade-tolerant plant, but if there is too little light, then it will certainly react to such neglect of its needs with massive yellowing and falling leaves. As a rule, gardeners often encounter a similar problem when moving their pet from the street (from the garden or from the balcony) into the house. A sharp change from the usual bright sun to a dimly lit room causes stress in the plant. To help him acclimatize faster and survive the move without loss, it is necessary to use additional illumination with phytolamps.

The opposite problem is sunburn leaves, due to which delicate leaf plates are covered with yellow, white, and sometimes shapeless spots burnt to black. To avoid such troubles, brought to Fresh air Hibiscus should be accustomed to the sun gradually, providing it with shading during the midday hours. The same measures should be taken for plants placed on the south window.

3. Temperature violation

Hibiscus is a heat-loving plant and prefers temperatures ranging from 18 - 30 °C. At lower values, its leaves may partially turn yellow and fall off. Reaction to heat Chinese rose the same, but here the situation can be saved high humidity air and abundant watering (the main thing is not to overdo it).

In addition, hibiscus also reacts to yellowing and dropping leaves. sharp changes temperatures, drafts, cold wind.

4. Pests

Spider mites are a real scourge of hibiscus. At the first stages of its invasion, this pest is practically invisible and does not betray its presence in any way, but the plant’s leaves soon begin to turn yellow and fly off en masse. Later on young shoots you can notice cobwebs, on the threads of which tiny moving dots become noticeable.

fight with spider mite should start as early as possible. As soon as it is detected, the crown of the bush must be treated with a targeted chemical. In particular, products such as Actellik, Aktara, Neoron, and Fitoverm have proven themselves to be effective against ticks.

5. Chlorosis

Hibiscus is one of the plants susceptible to chlorosis. With the development of this disease, the leaves of the plant turn completely or partially yellow, sometimes dark green veins are clearly visible on them. After some time, the leaves fall off, the young shoots dry out, and when further development process, the plant may die.

This disease can be caused by watering with very hard water, alkalization of the soil, and a lack of nutrients and microelements, in particular iron. As first aid, it is recommended to transplant the plant into fresh soil and feed it with fertilizers containing iron chelates.

6. Nutrients

In addition to iron, hibiscus needs a high content of potassium and magnesium, and a lack of the latter can also cause the development of chlorosis. But you should be careful with phosphorus and nitrogen when fertilizing. From excess nitrogen, the so-called “nitrogen burn” develops, in which the edges of the leaf blade turn brown, and excess phosphorus leads to yellowing of the leaves. Therefore, when choosing nutrient mixtures for feeding hibiscus, preference should be given to those in which the potassium content prevails over phosphorus and nitrogen, that is, it is better to exclude phosphate and nitrogen fertilizers from the hibiscus diet.

7. Natural causes

If the only leaf of a hibiscus has yellowed and fallen off, and the frightening process has stopped there, then there is no need to panic. This behavior is a natural process associated with plant growth and the replacement of old 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 pet attracts attention with its unusually bright and large red, pink, lilac, yellow or white flowers against a background of lush rich color green foliage.

Hibiscus – capricious plant, it is necessary to care for it 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 an early stage, then the hibiscus can still be saved.

Usually with abundant watering can not manage young plant. 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

A rose can feel great in bright sunlight 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 quantity. 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 It is recommended to choose 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 possible to understand 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.

Without the help of various chemicals there's no way around it. 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.
