Hibiscus leaves are rich in color

Yellowing leaves Chinese rose happens for the following reasons:

Lack or excess of light. Direct sunlight hitting the leaf plates burns the surface of the leaf. Exposure to intense light destroys the green pigment in the plant's leaves, causing them to turn yellow and then turn brown. Its deficiency also harms the culture, as the process of synthesis is inhibited. nutrients.
Too much or too little water. Hibiscus prefers moderate soil moisture. IN winter period Water the crop every 2 weeks. Intensive watering will provoke rotting of the root system and general wilting of the flower. Disadvantage - Causes leaf fall and wilting.
Air humidity. Rosa loves wet air, dry indoor air will cause the foliage to turn yellow.
Lack of space. A small pot provokes excessive compaction of the root system, which prevents the culture from developing and causes the leaves to fall and turn yellow. Transplant mature hibiscus large pots as needed.
Temperature. Hibiscus is a tropical species, so keep the room temperature +18 ... +30 ° С. Cold window sills and drafts are not suitable for this species. Temperatures above 30 ° C lead to overdrying of the soil, so water the flower more often during this period.
A change of scenery. The plant prefers to be in a pot in one place. The constant rearrangement of hibiscus from place to place causes it to lose its decorative qualities.
Nutrients. The lack of nutrients leads to chlorosis, which is expressed in yellowing of the leaves. The change in leaf color from green to yellow occurs gradually. Fertilize the Chinese rose from spring to autumn with complex fertilizers once a week, in cold weather - once a month. It is important not to overdo it with top dressing - hibiscus reacts poorly to an excess of phosphorus and turns yellow.
Pests. Yellowing and curling of leaves can cause aphids. The problem is solved by treating the plant with Fitoverm.

If you take care of indoor flower and in time to fight diseases, the plant will bloom brightly.

The Chinese rose, with the right content, will please with its decorative effect and will decorate the windowsill.

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. The plants that are on fresh 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. To make the flower feel comfortable, the temperature environment 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, when signs are found spider mite measures must be taken 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 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 the 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 often disturbed due to irrigation. 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 lateral shoots, which will help the hibiscus become green and lush even faster.

Hibiscus do not shed their leaves for no reason, they do not have a pronounced dormancy. If this is preceded by yellowing of the leaf, then this is a spider mite lesion, treat the plant, the place where it stood and nearby plants chemicals(actellik, fitoverm, fufanon, etc.), it is possible to drop leaves due to improper care, overdrying of an earthy coma, overflow, keeping the plant in a draft, in this case, the causes must be eliminated

Hibiscus are also very sensitive to hard water, water the plant only with well-settled water, and preferably with rain, melted water or, at worst, boiled water.

In order for the plant to quickly restore the leaves, spray it with a stimulator (epin, zircon), now you don’t need to feed it with anything.

And it doesn't drop for me! I myself am surprised ... moreover, the day before yesterday it bloomed!)

Maybe it depends on the environment...

try replanting, maybe the pot is small

Scale insects: brown plaques on the surface of leaves and stems, suck out cell sap. Leaves lose color, dry and fall off.

Control measures. For mechanical cleaning of pests, the leaves are wiped with a soapy sponge. Then spray the plant with 0.15% actellik solution (1-2 ml per liter of water).

Aphids - quite often affect hibiscus. They damage the leaves from the underside, the tops of the shoots. Damaged parts become discolored, the leaves curl, turn yellow and fall off.

I love hibiscus! They have lived with me for many years. Leaves may fall when:

Insufficient watering - need to be watered regularly,

When drafts - remove from the draft or cover with something (screen) when you ventilate the room,

When the air is very dry (heating in winter or hot in summer) - it is necessary to spray with non-cold water,

Hibiscus do not like to be in dusty or smoky rooms,

Hibiscus get used to the one who cares for them and get very bored when the owner is absent for a long time, while the leaves may fall,

Hibiscus can turn yellow and fall off when there is a sick person in the house or someone gets sick (two days before the illness) - it has been tested many times over many years.

Hibiscus do not like selfish and greedy people. If such a person is present for a long time where these plants are, then they cease to bloom and may fall off.

Just try to take care of them more tenderly, like a living creature - wipe the remaining leaves from dust, cut off old branches, spray, water, add fresh earth, protect from drafts - a kind and generous flower - it will definitely respond to love.

The most likely cause is drying out of the soil or drafts.

One of my Hibiscus started shedding yellow leaves after I changed his place, but this is nonsense - he grows back very quickly. Now they are blooming for me, even the one that sheds leaves.

Try spraying. My leaves also turn yellow in the fall and fall off, I recently brought it into the room from the balcony. In the spring it will grow after pruning.

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. The leaf 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 Sun rays its leaves are detrimental. 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 carried out regular watering plants (morning or evening every 2 days) especially in summer, hibiscus may not have enough moisture due to the small volume of the pot. An adult plant is 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. It will turn yellow leaves, 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. In both the first and second cases, the root system of 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 for 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.

Most flower growers grow hibiscus or Chinese rose. This is a hardy plant that normally tolerates temporary errors in care. But if the flower is not constantly watered or, conversely, flooded, it may soon die. The leaves of the plant will begin to turn yellow, the buds and flowers will fall off. If the situation is not corrected in time, the plant may die altogether.

Why do Chinese roses turn yellow and fall leaves? This is a sign that something is wrong with the plant.

Beauty and mysticism

The pot is small for the plant if the ground is dry. It needs to be transplanted urgently. A "cramped" pot can also cause the leaves to turn yellow. Indeed, often plants, dropping foliage, try to reduce the evaporation of moisture.

The new pot should not be too big. Perfect option- the container is 2 cm in diameter larger than the previous one. It is necessary to transplant hibiscus by the transshipment method. So the roots are minimally injured.

The new pot must have drainage. Transplanted Chinese rose in moist soil. The first watering should occur no earlier than on the 3rd knock.

For a plant, the capacity can be large. This is often evidenced by water accumulated in the pan. In this case, the roots may begin to rot and the leaves turn yellow. Transplanting to a smaller container will also help to correct this situation.

It is not uncommon for Chinese roses to turn yellow and fall leaves due to improper lighting. With a lack of light, the rose sheds the bulk of the green mass. Leaves often turn yellow on the shaded part of the plant.

Bright lighting can also harm hibiscus. Hibiscus leaves often dry out due to sunburn.

The ideal option is diffused lighting. The lack of natural light can be corrected by using fluorescent lamps.

Pay attention to exactly where the leaves turn yellow and fall. Chinese rose - beautiful plant. If the "problematic" leaflets are in the upper part of the crown, this may indicate a lack of nutrients. In this case, it is necessary to increase the concentration or frequency of feeding. But remember, there should be a measure for everything. The plant can also suffer from an overabundance of fertilizers.

Top dressing of Chinese roses can be carried out in the autumn-winter period. For this plant, any fertilizer is suitable for indoor plants, the main thing is that the composition has a low concentration of nitrogen.

Chlorosis

Viral diseases negatively affect the condition of the plant. A sign of disease damage is not only yellowing of the leaves. Spots appear on their surface. In plants affected by chlorosis, the leaves turn yellow, while the veins remain natural green.

This disease manifests itself when the acidity of the soil is incorrect. Chlorosis can affect the plant partially. Often yellowed leaves, underdeveloped roots and tops die off.

Using complex fertilizers, transplanting the plant into a new soil, you can overcome this disease.

IN preventive measures safety flower growers do not recommend watering the plant with hard tap water. It increases the acidity of the soil.

spider mite

Spider mites can also cause leaves to turn yellow. This pest can only be detected with a magnifying glass. Visually, you can notice a weightless web on the buds and leaves.

Pests can only be controlled with insecticides. Some growers use a cool soap solution. Leaves are washed with it. After the plant must be sent under the shower, and cover the soil with a film.

The plant is often restored for a long time.

Ideal conditions for the spread of spider mites - a room with dry air. In this case, you need to use humidifiers. You can leave containers with water near the plant. Spraying from a spray bottle has a beneficial effect on hibiscus.
