Chinese rose, aka hibiscus, the plant is quite hardy. She stoically endures care errors, but if they are not permanent. If the plant is constantly flooded or not watered at all, then the plant will begin to die. Leaves will begin to turn yellow and fall off, then buds and flowers. And if you do not pay attention to it, he will die.

This is not about natural aging, but about the causes that cause yellowing in a young plant. When a plant loses its beauty for other reasons. Therefore, the yellowing of the leaves is a signal that not everything is in order with the Chinese rose.

Why does this happen to a houseplant?

Yellowing of the leaves is partial, with spots cause different reasons. Let's consider them in more detail.

Important! For any flower, it is important to choose the right pot. It depends on how its root system will develop.

Whether the pot is correct is easy to check. Water the flower in the morning, and in the evening check the condition of the earthy coma in the middle of the pot. If the earth is dry, the vessel is small for him, we urgently transplant. Otherwise, his leaves will begin to turn yellow, as the flower will try to reduce the evaporation of moisture, dropping excess leaves.

The new pot should be 1-2 cm larger than the previous one. Transplantation is done by transshipment so as not to injure the roots. The pot must have good drainage. Transplantation is carried out in moist soil, watering begins on the third day.

If water constantly accumulates in the pan, the roots will begin to rot, the leaves will turn yellow and fall off.. This indicates that the capacity is large. As in the previous case, a transplant is needed. The plant, together with an earthen clod, is removed from the pot and checked for rot. If rot has appeared, we remove it, and powder the places of cuts with crushed charcoal. We transplant into a smaller pot, and adjust the watering.

Care errors

Chinese rose is a tropical plant and does not like drafts.. It can not be placed in the reach of fans and air conditioners. And during the ventilation of the room, it is recommended to cover it with a screen.
Wrong lighting. This factor leads to the following consequences:
1. With a lack of lighting, the rose sheds its leaves, guided by the principle: less leaves, less light is needed.
2. With a lack of sunlight, the leaves turn yellow on the shaded side.
3. The bright sun also harms - the leaves can get sunburned.
The best option is scattered sunlight. With a lack of natural light, fluorescent lamps will help.
The yellowing of the upper leaves of the flowers indicates a lack of nutrients.. You can fix it by increasing the dosage of fertilizers or the frequency of feeding. But this must be done carefully so as not to overfeed. Too much fertilizer also causes problems.
Low temperature environment . Since hibiscus comes from the tropics, it means heat-loving. The temperature in the room where the rose is kept should be in the range of 18-300 C. Otherwise, the plant begins to shed its leaves. During the dormant period, the temperature should not be below 15 degrees.

Diseases and pests

When a Chinese rose is infected with viruses, the leaves not only turn yellow, but also become stained. One of the common viruses is chlorosis. In a plant infected with chlorosis, the leaves turn yellow, and the veins retain their natural color.

Chlorosis indicates the wrong acidity of the soil. Sometimes the leaves of an infected plant turn yellow only where the source of the disease has appeared. And sometimes the leaves turn yellow and fall off, the tops of plants and underdeveloped roots die off.

You can fix it with a complex mineral fertilizer type "Uniflor-Micro", as well as transplanting into another soil. Spraying with iron chelate will also help. To avoid chlorosis, it is not recommended to water the flower with a hard tap water because it oxidizes the soil.

spider mite

Another reason for yellowing leaves is a spider mite.. You can detect it only if you examine the leaves with a magnifying glass. Without a magnifying glass, you can see a weightless web on the leaves and buds.

Save a diseased plant will help insecticides, which are sold in flower shops or leaf washing soapy water. After washing, the flower is sent under the shower. The soil in the pot is covered with a film.

Even with the help of insecticides, the plant recovers for a very long time.. To prevent the spread of the tick, it is necessary to treat it prophylactically twice a year. The treatment is carried out with drugs Agravertiv, Fufan or Aktlik. Processed three times at intervals of four days.

Spider mites start up where the air is dry. Therefore, in rooms where the air is dry, you need to use humidifiers or place a container of water near the flowers. Regular spraying is beneficial to hibiscus.

Attention! When pesticides are used in hot weather or overdosed, Chinese rose leaves turn yellow and fall off. Do not apply pesticides too often.

Chinese rose buds turn yellow and fall off for several reasons.:

After finding out the cause of the yellowing of the leaves of the Chinese rose, and after eliminating it, the flower will quickly recover. At this time, you can prune long shoots.

You can also learn more about why hibiscus buds and leaves fall, and we also talked about why the plant does not bloom.

rest period

In order for the hibiscus to grow beautiful, bloom magnificently and not get sick, it is necessary that during the dormant period it should be properly cared for.

First he needs to trim. This must be done not only to form a bush, but also in order to remove weak, poorly formed shoots. They still won't have flowers.

Reference! During the dormant period, the flower prepares for a beautiful lush bloom. Accordingly, the conditions of detention should be optimal: the air temperature should not be lower than 150 C.

When is the process natural and when is it not?

Leaves naturally turn yellow in old specimens preparing to die. Although in this case, you can try to revive it. This can be done by removing yellowed leaves and by pruning. And when caring for such a bush, you must follow all the rules of care

Conclusion

We have considered all possible reasons yellowing of hibiscus leaves. We also talked about ways to eliminate these causes. We hope that our article will help you grow your favorite lush and blooming profusely.

I sympathize with those who are faced with such a problem as falling buds. But why are the buds dropping on a completely healthy, seemingly ready-to-bloom plant? There may be several such reasons.

Falling buds and flowers from houseplants

1. Perhaps the plant is standing in a cold draft. During ventilation, cold air flows from the window can provoke not only the fall of the buds, but the death of the leaves.

2. The water used for irrigation is too cold. Water for irrigation should be soft, separated, at room temperature.

3. Transplanting a plant at a time when it has gained buds or has already blossomed has provoked abscission of buds or flowers. Even minimal damage to the plant's root system leads to stress, as a result, buds and flowers fall off. Before transplanting, wait until the plant has a pause between flowering.

4. A recently purchased plant was with buds, and was transported (transferred) in unsuitable conditions (shaking, severe frost).

5. Too dry earth in a pot, long breaks between waterings, or, conversely, too damp earth. Adjust watering. The frequency of watering depends, firstly, on the type of plant (cacti and succulents prefer drought, and for calathea it is desirable that the earth is always damp), and secondly, on how quickly it dries upper layer soil: in summer, watering can be 2-3 times a week, in winter - 1 time in 7-10 days.

8. Incorrectly chosen fertilizer for top dressing or not following the dose of fertilizer can lead not only to the fall of the buds, but also to the loss of the entire plant.

Falling buds and flowers from garden plants

1. Transplantation of flowering or flowering plants into open ground is very often accompanied by the dumping of all buds, flowers or set fruits. This is due to damage to the root system during transplantation into open ground. It is advisable to do transshipment of plants.

2. Spring night frosts, in summer there is a large difference between day and night air temperatures, which negatively affects plants.

3. Not enough moisture. Water garden plants correctly, only in the morning or evening hours, make sure that moisture passes into the soil, and does not flow along the beds or flower beds.

4. Too heat air. Here, of course, we are not subject to change anything)), but those plants that are very dear to you can be shaded from above in the hottest midday hours, using old umbrellas, you can make awnings from newspapers, agrospan.

5. After prolonged rains or excessive watering, the soil is compressed, a crust has formed on the surface, the roots of plants are suffocating. Constantly loosen the soil, alternate watering with loosening, provide air access to the roots of plants.

6. Garden plants lack nutrition. Fertilize with phosphorus-potassium fertilizers so that the buds do not fall off and the flowering is long.

7. Incorrectly selected fertilizer or too high a dose of fertilizers. If you carried out top dressing, and in the morning all the buds, flowers, leaves turned yellow, then most likely the concentration of the fertilizer was very high. Water the plant generously. Excess fertilizer along with water will go into the lower layers of the soil.

8. In open ground garden plants can be attacked by various pests. Various caterpillars can gnaw buds and flowers.

In hot and dry weather, the attacks of thrips and spider mites are especially noticeable: the buds fall off without opening, the buds do not open for a long time, the buds and flowers are ugly, the flowers crumble very quickly. If the weather remains dry and hot for a long time, carry out pest control every week.

9. The cause of falling buds and flowers can be a strong wind, heavy rain, hail.

10. There are no visible reasons for dropping buds and flowers, but the buds still fall off? Treat plants with drugs that increase immunity, protect plants from stress factors: zircon, energen, ovary, kendal, megafol.

Hibiscus drops buds. Unopened hibiscus buds fall. Hibiscus is dying - how to help. Read today's article to resuscitate hibiscus.

Let's analyze all the options why hibiscus sheds buds that have not yet opened, starting from the first stage of reproduction, ending with an adult plant.

Why hibiscus drops its unopened buds:

Weak root system.
microclimate changes.
Dried land.
Lack of light / changes in light regime.
Weak run.
Haven't been transplanted for a long time.

You can detail the problems in caring for hibiscus for a long time. Let's group them according to the following parameters: lighting and temperature, planting, transplanting and top dressing, watering.

Retreat: Young hibiscus seedlings recently propagated from cuttings may drop unopened buds due to weak roots and lack of nutrition. If this reason is closest to your problem, read about the nuances of feeding.

Temperature and lighting for hibiscus

For hibiscus bloom are taken into account temperature conditions, both winter and summer, since the first season creates a certain springboard for the development of buds. At rest, hibiscus prefers an average temperature of + 15 ° C - this contributes to the uniform laying of the kidneys.

For forcing buds and shaping inflorescences suitable temperature +20-23° C. Minor fluctuations are acceptable. Minimum temperature during this period, which does not harm the condition of the flowers, + 12 ° C - typical for the night or temporary weather changes.

Take note: during the period of decreasing temperature indicators, hibiscus do not overmoisten and try to protect against drafts.

Hibiscus lighting is always shaded - the Chinese plant does not need direct Sun rays to form their rose-like buds. It is impossible to put hibiscus in a well-lit place, and even in the summer, when the rays sting delicate leaves and buds.

Where to put hibiscus: in the corridor; in the southeast, south side; not far from the window - on the table, bedside table.

Hibiscus transplant: the nuances of working with the soil

Hibiscus transplanted and propagated as the plant develops. A young plant is transplanted every year, a little older - 1 time in 2-3 years. What is the rationale for this? The root system of hibiscus is active, shoots develop quickly. The substrate is quickly depleted, and the roots of the flower become cramped in the old pot.

It is impossible to combine transplantation and propagation by cuttings in one day - first plant the cuttings, and after a few days move the hibiscus. The pot is taken a few centimeters more, with a mandatory drainage bottom, adding additional loosening by laying out the drainage layer.

Land for planting hibiscus:

Pebbles at the bottom.
Earth from 1 part of leaf earth.
2 parts sod substrate.
1 part humus.

Transplant with pruning of damaged roots, sprinkling the places of cuts with an anti-stress preparation.

How to organize watering hibiscus:

In winter: 1 time in 4-5 days, checking soil moisture. Do not spray the plant.
Warm period: 1 time in 2-3 days, also partially drying the earthen mixture. Can be sprayed in summer.

Prevention of diseases and pests: the use of settled water, moisturizing as necessary, proper placement, periodic dressing with Fitosporin or another universal fungicide - during transitional periods, at the end of winter - and soil disinfection before planting.

Top dressing hibiscus, to Not dropped buds:

From the beginning of spring to the end of autumn: a mineral complex, alternating with organic fertilizers.
Spill the earth in a pot with water so as not to burn the roots.
A solution of 1 part mullein to 10 parts water.
Universal minerals and trace elements.
Procedure frequency: 1 time per month.

The most common pests indoor hibiscus- white aphids and spider mites. Aphid infestation is evidenced by insect populations that have accumulated on the underside of the leaves, as well as small white larvae that slowly move throughout the plant. The hibiscus reacts to this pest by wilting and then dropping buds.

If, in addition to dropping flowers, the leaves of the tree turn yellow and fall, then the reason may lie in the decay of the root system. This process is provoked by putrefactive bacteria that start in the soil when watering plants too much. cold water. Only transplanting and replacing the soil can save the flower.

Mistakes in care

Often hibiscus drops buds for a reason improper care or non-compliance with the conditions of detention. This flower is so capricious that even a small movement within the same room can react with a massive drop of buds.

Another mistake of flower growers is to try in any way to stimulate the flowering of hibiscus, forgetting that he needs a dormant period. As a rule, it comes in winter. At this time, top dressing should be completely stopped, and watering should be done only occasionally, as the soil dries. If the plant does not have a rest, it will not be able to set buds.

Watering mode

Insufficient or too rare watering is very often the reason that the hibiscus buds fall off. With a lack of moisture, the roots dry up, and in order to maintain their strength, the plant begins to get rid of leaves and flowers. You can correct the situation by restoring the irrigation regime. Hibiscus is moisture-loving, so it must not only be watered, but also regularly sprayed with warm settled water. To prevent the lower roots from drying out, pour water into the pot tray.

Lighting and temperature

Lack of sunlight also negatively affects the flowering of hibiscus.

In the shade, the formation of chlorophyll slows down near the tree, its leaves become pale, and growth slows down, which again leads to the dropping of flowers and unblown buds. To prevent this from happening, the pot with the plant should be placed in a well-lit room, where the windows are hung with a light curtain. Since direct rays are harmful to him, sunlight should be bright, but diffused.

For a comfortable life, hibiscus requires a temperature in the range of + 18–22 ° C. These are averages. The lowest threshold for a flower is +15 °C, and the highest is +25 °C. Try to maintain this mode, as any temperature drop will immediately provoke drying and falling of the buds. Hibiscus are also very sensitive to drafts.

Fertilizer and stress

During flowering, the tree consumes a lot of energy that needs to be replenished with top dressing. For this purpose, it is better to choose complex fertilizer containing nitrogen, potassium and trace elements. Many flower growers note that hibiscus do not like mixtures with high content phosphorus - flowers can even fall off from such top dressing. However, you should not get carried away with nitrogen either, because instead of flowers you will get only green foliage.

Another reason for bud drop in hibiscus is stress. This concept refers to any actions that lead to a change in the habitual habitat of a plant: moving to another place, transportation from a store, draft, watering with cold water. Try to provide your pet with stable conditions, especially during flowering.

If you want not a single bud to fall from a tree, do not move it or replant it until flowering is over.

How to save a flower

Usually, when correcting errors in care, hibiscus pleases with abundant and long flowering for a long time. But what to do with crumbling buds and how to restore a flower? If the bud fall is massive, it is necessary to prune the entire plant. Dried leaves and flowers should be removed, and each shoot should be shortened by 10 cm - this procedure stimulates the tree to lay new buds and promotes early flowering.

If the hibiscus is affected by pests, then a thorough disinfection with insecticides is necessary. If aphids are affected, the flower must be washed running water or soapy water, and then treat with a special preparation. When the roots rot, the plant is removed from the pot, all damaged roots are cut off, and the cut points are disinfected with a solution of potassium permanganate or sprinkled with charcoal. In this form, the hibiscus is transplanted into a new pot with a completely renewed substrate.

Hibiscus is a fairly hardy plant and can forgive some care mistakes. But, despite this, agricultural technology in the cultivation of the "Chinese rose" is very important and its non-compliance leads 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 is non-infectious and infectious.

Non-infectious chlorosis appears with violations in the nutrition of the plant: lack or excess of nitrogen, magnesium, potassium, iron. Potassium and magnesium are inherently competing elements. An excess of one leads to a deficiency of the other. Potassium is needed flowering plant. With its deficiency, the plant does not bloom, or the flowers are slightly colored, and the branches are thin. Magnesium deficiency leads to chlorosis. Iron deficiency also causes yellowing and leaf fall. In order to prevent this, the water for watering the plant must be defended and iron chelate added to it.
infectious chlorosis caused by viruses, fungi and pests. Dust removal, timely fertilization, transplanting and pest control will help to avoid these diseases.

Sunburn. Direct sunlight, falling on a plant that has not yet adapted, partially destroys chloroform in them, as a result of which the leaves become covered with white spots of burns. This temporary phenomenon is observed if the flower was moved from a greenhouse or a place with a lack of consecration to the bright sun. The hibiscus quickly adapts to changes in light and new leaves will grow back normally. To avoid the loss of decorativeness and not to injure the plant, it must be accustomed to change by taking it out into the sun for an hour a day, gradually increasing the length of stay.

Diseases caused by pests

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

Spider mite (web on hibiscus). In the affected plant, the leaves fade and become covered with yellowish specks. Subsequently, extensive dried areas appear on them. The underside of the leaves is covered with a web 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 with Lightning, Fitoverm, Akarin, etc.

Aphid. Aphids are attracted to the young leaves and buds of the plant. When damaged, they deform and become sticky. For the prevention and control of the disease, the plant is treated with soapy water, tobacco dust, Biotlin, Akarin, Decis, etc.

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

Shields and false shields. Brownish or pale brown tubercles appear on the stems of the plant. With a small lesion of the plant, pests are removed mechanically, and the affected areas of the plant are wiped with kerosene or mineral oil. With severe damage, the plant is best treated with an insecticide.

Bacterial spotting. The edges of the leaves of the affected plant are covered with rotting yellow spots. For the prevention and treatment of the disease, the plant is systematically examined and treated with Fundazol, Cumulus, Euparen, etc.

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

Vascular wilt. Called by fungi. In the affected plant, the branches and trunk rapidly dry out, sometimes not having time to lose foliage. To treat the disease in the affected plant, the damaged parts 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. Midges midges lay their eggs in tiny hibiscus buds, so to prevent the disease, yellowed buds are collected, preventing them from falling, and the soil under the flower is treated with a preparation from soil pests.

Symptoms of diseases

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

Hibiscus leaves are falling. Stress, lack of moisture. It is necessary to create peace for the plant and spray.

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

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

Hibiscus leaves wither. Nutrient deficiencies. It is necessary to feed the plant with nitrogen and phosphorus preparations.

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

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

What to do if he dies?

If your Chinese rose fell ill, do not despair, perhaps it will be possible to resuscitate him. Hibiscus is unpretentious, and it is quite possible to treat it at home.

On this moment many preparations have been developed for pest control, they can be purchased at specialized stores or use folk methods by treating the plant with a solution of soap, tincture of tobacco or pepper.

Folk remedies for hibiscus pest control

Pepper tincture (from aphids, ticks) - Dry pepper is poured with water in a ratio of 1: 2 and boiled for an hour, then insisted and filtered. For spraying a plant, 10 g of the drug is diluted in one liter of water and soap. Soap should be taken about 5g per liter.

Tobacco tincture (from aphids, thrips, ticks) - 1 kg of tobacco dust or tobacco is boiled in 10 liters of water for two hours. Insist 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 preparation, 200 g of potassium soap is diluted in 10 liters of water.
Mustard tincture (for ticks, aphids) - 50g of mustard is boiled in a liter of water and insisted. Before use, the concentrate is diluted in 20 liters of water.

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