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, since 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. She already misses 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 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 Chinese rose 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 earthen coma depletes not only 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 here sudden changes 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 nutritional elements important for this instance. 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 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 the indoor plant turn yellow, wither and begin to actively large quantities fall off 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, they offer drugs such as Fitoverm, Aktara, Aktellik 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, when there is a large amount of alkali in the soil, when insufficient quantities fertilizers and fertilizing, as well as iron deficiency. You can save an indoor flower by replanting it in a new soil mixture and adding fertilizers containing iron to it.
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.

In the photo below you can see yellow spots on hibiscus foliage, as well as other signs of yellowing.
Improper watering
First of all hibiscus reacts by yellowing leaves to improper watering . This plant loves water, so it needs to be watered abundantly and often.
On hot days summer days You can water your hibiscus every day.
It is important to maintain balance and not overdo it. A flower can shed its leaves if it is flooded with water and the roots are like in a swamp.
Incorrect temperature
Do not forget that the Chinese rose is, first of all, tropical plant that's why it loves warm air. The best option would be to maintain the room temperature at least 16-18 °C. The flower also does not like too high temperatures, so on summer days it is recommended to move it to a cooler place if the thermometer rises above 21 °C. Incorrect lighting And again you need to find golden mean. Hibiscus loves to bask in the morning light, but must be protected from the afternoon sun.
The hot rays of the sun can cause burns on the tender leaves of the hibiscus, which it will eventually shed.
If there is insufficient light, the flower may shed its leaves., leaving for yourself a few leaves that need the small amount of chlorophyll produced by the hibiscus under such lighting.
Dry air
This can be easily fixed with a simple spray of water. You can simply spray the air in the room and directly the leaves of the Chinese rose. You can place a small container of water near the flower pot so that it evaporates. Many people use cut-off bottles from mineral water. They are convenient and take up little space.
Soil chlorosis
Why else does an indoor flower shed its leaves? The reason may be a situation in which the acidity of the soil changes. When the formation of chlorophyll in the leaves is disrupted and photosynthesis activity decreases, the plant suffers from chlorosis. Most often, this is caused by watering the plant with unsettled water. This situation can be corrected by adding necessary fertilizers with magnesium and adjusting soil acidity.
Frequent change of location
Hibiscus does not like to be moved from place to place and may react by yellowing leaves. Sometimes, in order for a plant to stop blooming or shed its leaves, it is enough to turn it in the other direction.
Experienced flower growers say that you need to gradually rotate the plant by 15 degrees, giving the flower time to get used to the new location.
Pests
The most common reason why hibiscus leaves turn yellow and then fall off is the presence of pests on the flower. Very often, pests are not visible to the naked eye. In order to identify the cause, you need to take a magnifying glass and carefully examine the leaves on both sides.
- Shchitovka. In this case, you can see on the leaves brown spots. What to do? It is necessary to spray the plant with a solution of the insecticide Actellica.
- Aphid. Aphids can be detected using a magnifying glass. A characteristic feature The signs that the plant has been attacked by these pests are curled, yellowed leaves. The drug Fitoverm can help.
- Spider mite. The appearance of a problem associated with spider mites is usually associated with the dry air in which the flower is located. Between the leaves you can see thin threads of cobwebs. You can use the folk way fight against spider mites - treat the leaves soap solution(must be used laundry soap). The drug Vertimek also helps.

We invite you to watch a video that answers the question: why do hibiscus leaves turn yellow and fall off:
Look after it beautiful flower- Chinese rose, it’s not at all difficult, you just need to create the conditions necessary for its maintenance. Everything is quite simple - the main thing is to be attentive to your pet: protect it from drafts, provide moderate but regular watering, choose a pot the right size. Be sure that then hibiscus will bloom magnificently in your home.
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 unpleasant surprises to its owners. 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 the windowsill, covering the plant in summer from direct sun rays 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 wrong mode glaze. 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, hibiscus has to remove the entire root system, which is 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 can be the infestation of hibiscus by mites, which causes characteristic yellow spots to appear on the leaves of the plant. In this case, the problem can be solved by treating the hibiscus with a soap solution or with special chemicals sold in flower shops.

Many plants that came to us from other countries are firmly established 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.
Deficient watering
If the hibiscus grows at sufficient 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 on fresh air, respond well to use special devices for automatic drip irrigation.
Overwatering
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.
Excessive air temperature
If it is very hot outside or in the house, the hibiscus can actively shed its leaves, which turn yellow before this happens. You can cope with such a nuisance with the help of active watering, which will provide the crop with a sufficient amount of liquid.
Cold
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, he will suffer appearance and various diseases may develop. 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.
Lack of lighting
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.
Spider mite
An infected bush has a diseased appearance and in some cases may become completely bare. Therefore, when signs are detected spider mite you need to quickly take measures to save the plant. Therapy in this case is carried out using special compounds– insecticides that 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.
Drafts
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.
Chlorosis
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 area, we can conclude that the Chinese rose needs certain nutrients. 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.
Excessive use of pesticides
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 a new one in a fairly short period of time. green mass. 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.
