Hibiscus leaves turn yellow: causes, effective treatment
Don't know what to do when hibiscus leaves turn yellow and fall off? Expert advice on diagnosing the problem and effectively fixing it will help more than ever.
Hibiscus stands by the window. Its leaves are turning yellow. sheet plate first changes color - brightens, then turns yellow. The hibiscus leaf falls off. Cause: a large number of direct sunlight, which lead to leaf scorch. Hibiscus needs diffused light, especially variegated varieties, but direct sunlight is detrimental to its leaves. Control measures: shade the plant.
Why do hibiscus leaves turn yellow and fall off? This is due to the drying of an earthy coma in a pot.. Even if you regularly water the plant (morning or evening every 2 days), especially in summer period, hibiscus may lack moisture due to the small volume of the pot. mature plant planted in a pot, the diameter of which fully corresponds to the size of the root system. How to know if the pot is suitable for hibiscus? To do this, water the plant in the morning. By evening, you need to check if the earth has dried up in the middle of the pot. If so, then the bowl is too small for the hibiscus. Its leaves will turn yellow, as the plant tries to reduce the evaporation of moisture from the surface of the foliage, dropping excess leaves. In this case, the plant is transplanted into a new container, the size of which is larger than the previous one, by transshipment, without violating the integrity of the earthen coma. Watering is carried out only on the third day after transshipment, taking into account the fact that transplantation was carried out in moist soil.
Hibiscus will turn yellow leaves if it gets too much moisture.. There are several factors at play here:
- plant overflow. Although hibiscus consumes a lot of water, especially on hot days, due to the fact that it is able to accumulate moisture in the roots, it is not difficult to overwater it. Harmful to the plant and the accumulation of liquid in the pan. Both in the first and in the second case root system the plant begins to rot, which is reflected in the hibiscus leaves. They turn yellow and fall off. Control measures: moderate watering, make sure that water does not accumulate in the pan. Remove the plant from the pot along with the earthen clod. Inspect the roots for rot. If there are any, they are removed, and the hibiscus is transplanted into a smaller pot than the previous one. Good drainage is a must;
- large pot size. In this case, a large amount of moisture accumulates in the soil, which the hibiscus root system is not able to absorb. As a result, the roots rot and the hibiscus leaves turn yellow. In this case, you need to reduce the size of the pot and normalize watering.
Why do indoor hibiscus leaves turn yellow? Leaves of hibiscus may turn yellow due to lack of nutrients.. You need to feed the plant often during intensive growth and development (spring, summer). But for this, liquid complex fertilizers are used to not flowering plants. Hibiscus fertilizer should not contain a lot of phosphorus, which is detrimental to the flower. Top dressing is better to make on cloudy days, when the earthen ball in the pot is well saturated with water. Optimal chemical composition hibiscus fertilizer: N:P:K (nitrogen, phosphorus, potassium) 9:3:13 or 10:4:12 or 12:4:18. Fertilizer with the following composition N:P:K 16:20:27 or 15:21:25 can harm the plant. From an excess of phosphorus, hibiscus leaves can also turn yellow.
The hibiscus leaf turned yellow, but the veins remained a bright green color. Hibiscus has chlorosis, that is, the leaf does not produce enough chloroform, so the hibiscus leaves turn yellow. Control measures: make up for the lack of trace elements. This is magnesium, which in small quantities is part of complex fertilizers. Chlorosis of hibiscus leaves occurs as a result of watering the plant with unsettled, untreated water.
Flowers of the genus Hibiscus belong to the family of mallow plants. In total, there are about 250 species in the genus. They grow in the tropics: in India, China and Asia. Only one plant of this species is suitable for indoor maintenance - Chinese rose (or Chinese hibiscus). Also in early XIX century hibiscus became popular in Europe, and eventually appeared in Russia.
The plant served as an adornment of the most famous botanical gardens. And in Hawaii, for example, the flower was (and still is) a symbol of femininity. Local girls often adorn themselves with its buds, which look very feminine and spectacular in their hair. In its homeland, the Chinese rose is known not only for its beauty. Her flowers are used in medicine, made from them natural paint for textiles and even for drinks.
Hibiscus is a rather unpretentious plant and does not need any kind of special care. The rose grows rapidly and already six months after cuttings, it can throw out buds of amazing beauty. At home, you can find red, yellow, pink and white bell flowers. In nature, the colors of this plant exist many times more.
Today we will not talk about the beauty of hibiscus, but about the troubles that await flower growers who grow it. After all, any houseplant can get sick, and the Chinese rose is no exception. The fact that a flower is dissatisfied with something can be recognized by the state of its leaves. And first of all, it is necessary to find out why he fell ill, to find the reason that affected him not in the best way.
Why do Chinese rose leaves turn yellow?
It must be said that without any information about the content of the rosette, it is impossible to name the cause of her illness with certainty. Below we have collected the main facts that tell why hibiscus leaves turn yellow and fall off. Having studied them all, you will definitely help your plant regain its former beauty.- Insufficient watering
- Over watering
- Very high air temperature
- Low temperature environment
- Being in direct sunlight
- lack of lighting
- spider mite
An infected bush looks sick and can become completely bare if urgent action is not taken. Treatment is carried out with special preparations - insecticides, which can be purchased at a flower shop. It should be noted that getting rid of spider mite pretty hard. It is better to do prevention twice a year by spraying the plant than to restore it for a long time.
- Presence of drafts
- Chlorosis - improper acidity of the soil
- Excessive use of pesticides
How important are fertilizers?
Suppose you have studied all the above facts and were able to correctly establish the cause of the disease. And even this reason has already been eliminated - the leaves have ceased to fall off. Well, now it's time for the good news: the hibiscus will grow new green mass pretty quickly. Perhaps if the branches of the plant were too long, it was washed off to cut them to form a beautiful bush. Pruning stimulates the appearance of side shoots. This is all the more true if the plant has lost almost all the leaves.Chinese rose does not like too much phosphorus. If there is an excess of it in the soil, then the plant will suffer. But it will not remain silent - it will immediately show its dissatisfaction with the yellowed leaves. If you do not pay attention to this, then the flower will die. Why? - you ask. Yes, because it will no longer be able to consume other trace elements.
All living organisms on earth need nitrogen and the Chinese rose is no exception. Plants use it in all their life processes. But too much nitrogen fertilization can lead to so-called fertilizer burn, due to which the tips of the leaves begin to darken.
Whatever fertilizer you use, if you notice dry and darkened leaf edges, stop applying it immediately. Further watering should be exclusively clean water. Let the plant rest for a couple of weeks. When the time comes to resume feeding, apply a solution with a lower concentration. You can find out the required concentration empirically, gradually reducing the dosage until the plant stops responding to the fertilizer with leaf burns.
So we looked at all the most common hibiscus diseases. As you already understood, the plant responds to almost every disease by yellowing and dropping foliage. Try not to bring the rose to a critical state, take care of it properly. And she will thank you thick and lush crown, as well as frequent and abundant flowering.

Does not apply to plants that are difficult to care for. They usually require minimal care and acceptable growing conditions. But bad things happen too. In particular, hibiscus leaves turn yellow and fall off. Most often this happens with indoor hibiscus. There are many reasons for this unfortunate phenomenon. Therefore, in order to fix the problem, it is necessary to establish the cause as soon as possible and begin to eliminate it.
Leaves turn yellow and fall off indoor hibiscus: causes and what to do
natural cause
It often happens that there is simply no reason for alarm and panic. If the hibiscus leaves for the most part remain green and nothing happens to them, but one or two leaves turn yellow and fall off, then this phenomenon is normal. Hibiscus is a plant with intensive growth that does not stop even in winter. So there is a natural replacement of leaves - new ones grow up, old ones die off.
Incorrect content temperature
For this reason, mass fall of hibiscus leaves occurs mainly in winter. This happens if the temperature of the plant content. If many houseplants calmly tolerate a temperature of +12 degrees, then it is not suitable for hibiscus. The minimum temperature at which it will feel normal in winter and subsequently bloom profusely is +15 - 16 degrees. But at such a low temperature, a number of other rules must be observed: optimal watering, air humidity, protection from drafts, and avoid hypothermia of an earthen clod. Even a slight deviation from this set of rules will result in yellowing and falling of hibiscus leaves. Therefore, beginner growers who do not have sufficient experience in providing optimal conditions should refrain from it and move hibiscus to more warm room with a temperature not lower than +18 degrees.
Wrong watering
The reason that the indoor hibiscus leaves turn yellow and fall off, it can become either insufficient or excessive. Under normal room temperature, the earth in a pot should always be wet. But only slightly damp! Damp, swampy land can cause the death of the root system and the entire plant as a whole. In such soil begins active development putrefactive bacteria and harmful fungi, the supply of nutrients to the plant is suspended. As a result, the plant begins to wither and, if no action is taken, it will almost certainly die. The first signal - the leaves turn yellow and fall off. Young plants are especially susceptible to this. In a young hibiscus, the root system is still not sufficiently developed, and it is difficult for it to cope with a large amount of moisture, especially if the pot was chosen too large when planting, “for growth”. In this case, you must immediately transplant the flower. It is first necessary to thoroughly clean the roots of the hibiscus from the remnants of the earth, remove all rotten and damaged roots, and treat the roots with a fungicide solution. Before planting, it is advisable to powder the roots with Kornevin powder. After planting in fresh ground, spray the entire ground part of the flower with Zircon or Epin
No less dangerous is the drying of the earth. Prolonged drying will almost certainly destroy the plant irrevocably. In this case, nothing can help the plant. But if you notice that the leaves of the hibiscus have begun to fade and turn yellow, and the earth in the pot is dry, then you should immediately water the plant.
Wrong lighting
By itself, the lack of light can in no way harm indoor hibiscus. This plant grows well both in bright light and in a shaded place. The danger is a sharp change in illumination. This usually happens when moving hibiscus from indoors to outdoors in the spring and back in the fall. This does not lead to fatal consequences, but it affects the decorativeness of the plant, the hibiscus leaves begin to turn yellow and fall off. After a while, the plant adapts and grows new leaves, but first it will bring the owner a lot of unpleasant minutes. To avoid this, accustom the plant to change light gradually, do not put it immediately in bright sun after shade and vice versa.
Wrong feeding
Unbalanced can also lead to yellowing and falling of hibiscus leaves. The most important components for its nutrition are magnesium and potassium, they must be present in the composition of fertilizers. An excess of phosphorus and, in particular, nitrogen can cause particular harm to a flower. An excess of this element can cause nitrogen burn. Therefore, when choosing a fertilizer for indoor hibiscus, give preference potash fertilizers with magnesium content. Phosphorus and nitrogen can also be contained in them, but in small concentrations.
Chlorosis
Enough common cause where hibiscus leaves turn yellow and fall off. This applies not only to indoor hibiscus. Almost all plants can be affected by this scourge. The cause of leaf chlorosis can be too hard water, a high concentration of alkali in water and soil, and a lack of fertilizers. But the main cause of leaf chlorosis is iron deficiency. If the above reasons are eliminated or absent, then it is necessary to treat the plant with Iron Chelate or a specialized antichlorosis drug. Processing is carried out both by watering and by leaf (according to the instructions for the preparation). If the process has gone far, then the hibiscus should also be transplanted into fresh soil.

Many plants that came to us from other countries are firmly entrenched in apartments and on household plots amateur gardeners. And one of these fairly common crops is Hibiscus. Its homeland is considered to be the tropics - 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 to itself, differing in sufficient unpretentiousness. However, in certain cases, the leaves of the flower begin to turn yellow and fall off. What can cause such trouble? Why do hibiscus leaves turn yellow and fall off? What to do about it? What is the best way to deal with adversity?
Of course, without sufficient information about the growing conditions of hibiscus, it is impossible to unambiguously and accurately determine the causes of yellowing of its leaves. However, there are certain factors that most often provoke a similar problem.
Scarce watering
In the event that hibiscus grows at enough high temperature, it needs systematic watering with a significant amount of water. If the plant is hot, then watering can be carried out twice a day. Those plants that are in the open air respond well to the use of special devices for automatic drip irrigation.
Over watering
In the event that the leaves began to turn yellow and fall off during the cold season, it may well be that such a nuisance was the result of excess moisture in the soil. As we have already said, the Chinese rose loves water very much, but it cannot feel normal in a cold swamp in the root system.
Excessive air temperature
If it is very hot outside or in the house, hibiscus can actively shed foliage, which turns yellow before that. You can cope with such a nuisance with the help of active watering, which will provide the culture with a sufficient amount of liquid.
cold
Do not forget that the Chinese rose came to us from the tropics, respectively, she loves warmth very much. In order for the flower to feel comfortable, the ambient temperature should fluctuate between eighteen and thirty degrees. Otherwise, it will suffer appearance and various diseases may develop. For example, if you place a flower pot next to winter window, he can respond to such a cold snap by quickly dropping leaves.
Lack of lighting
Normal access to sunlight is a true source of life for the Sudanese rose. With a lack of light, the plant can actively shed its leaves, thus trying to reduce its need for lighting. This process can continue until there are literally a couple of leaves left on the hibiscus.
spider mite
The infected bush has a diseased appearance and in some cases can be completely bare. Therefore, if signs of a spider mite are found, it is necessary to take measures to save the plant as soon as possible. Therapy in this case is carried out using special formulations- insecticides, which you can easily buy at a flower shop. But in fact, getting rid of the spider mite is quite difficult. Experts recommend carrying out preventive spraying of plants once a year to prevent the occurrence of such a problem.
drafts
Even slight movements of air may not please the hibiscus and cause it to shed its foliage. Therefore, try to protect your plant from windy weather in the house.
Chlorosis
There are several variants of chlorosis. Yellowing of the 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. It may well be that your pet suffers from soil acidity disorders or simply lacks nutrients. Now the acidity of the soil is quite often disturbed due to irrigation with tap water, which is characterized by increased rigidity.
Overuse of pesticides
This reason for the yellowing of hibiscus leaves is the most rare, but, nevertheless, probable. If you've been using pesticides during a particularly hot time, or if you've accidentally overdosed, your hibiscus leaves may turn yellow and fall off. In addition, such a problem can be provoked by too frequent use of pesticides.
If you have identified the cause of the yellowing of the leaves of the hibiscus and promptly eliminated it, the foliage will stop falling off. The Chinese rose is able to build up a new green mass in fairly short rocks. You can help your pet a little to form a beautiful bush - cut too long or damaged branches. Pruning activates the processes of the emergence of side shoots, which will help the hibiscus become green and lush even faster.
