Why do Kalanchoe leaves turn yellow? Caring for indoor plants, Kalanchoe leaves are falling off. Why do Kalanchoe leaves curl and what to do? Kalanchoe leaves curl and dry
By giving him necessary care, you will achieve both proper development and flowering.
But if it starts to hurt, its leaves become stained, or you find small insects– urgent measures need to be taken.
Leaf diseases
Yellowing of leaves
Why does Kalanchoe turn yellow? and what to do about it? This usually happens after flowering. The stem is stretched and exposed from below.
This is a sign of exhaustion. New soil and intensive fertilizing are needed.
Replant the plant in a new substrate. After transplanting, feed it with Zircon solution.
Why do Kalanchoe often The leaves turn yellow and dry at the tips? This is primarily due to a lack of boron and the flower needs to be fed with fertilizer containing a high content of this substance.
Curling leaves
Why do Kalanchoe leaves curl? Kalanchoe leaves curl, most likely due to damage to the root system.
The reason for this is excess water. Remove the plant from the pot and inspect the roots.
Damage must be cut out, the healthy part must be washed in a weak solution of potassium permanganate.
Then treat the cuts with charcoal powder and plant the surviving part in fresh soil.
Why do Kalanchoe leaves curl?
If leaves curl and at the same time change color to burgundy, which means that the plant is in a place that is too lit, it for a long time direct rays fall during the day.
In this case, shade the flower and spray it during the day.
The leaves are falling
Why does Kalanchoe shed its leaves? U Kalanchoe fall off leaves due incorrect content V winter period. This happens when the flower is kept in a stuffy room, next to heating radiators.
If you notice this, move it to a cooler room. It is advisable that the temperature in it should not exceed 15 degrees. In this case, the winter will pass without losses.
So why leaves are falling in Kalanchoe and what to do? Another reason for this may be coolness that is not combined with humidity - it appears on the leaves. mold or black spots. It's a fungus. Fungicides will help destroy it.
Why does Kalanchoe wither?
What to do if Kalanchoe withers? Why does the plant soft leaves? The reason depends on the age of the plant.
If the root is rotten, then moisture does not enter the leaves, but accumulates in the soil.
This can also happen with irregular watering.
If the soil dries out too much and is then watered too much, the plant may also wilt.
Watering should be done when dry, not dry.
In an adult Kalanchoe, the leaves wither due to aging. Rejuvenate him. Separate the cuttings and replant.
Black spots on leaves
If Kalanchoe leaves turn black, this indicates the presence of a fungus. This occurs due to an excess of moisture, the soil does not dry out and its aeration is impaired.
Change the soil, increase its looseness by adding sand. Adjust the watering in the future and then the leaves of the Kalanchoe will not turn black.
Brown spots on leaves
Dry brown crusts on the leaves - it's Kalanchoe disease, called dropsy. It arises from temperature changes combined with waterlogging.
Move the Kalanchoe to a warmer, drier place and reduce the amount of water used. Be careful not to get on it cold air, for example, during ventilation.
White coating on leaves
Kalanchoe covered white coating due to the fact that irrigation water too hard. It contains salts and lime impurities.
It needs to be softened: settled, filtered. The best remedy is freezing and then thawing.
To soften once a month you can contribute to it citric acid on the tip of a knife per liter. You can add three percent vinegar - 1 teaspoon per liter. The liquid with acid is left to sit for two days so that all the salts settle, then drained and used for irrigation.
The leaves have fallen
Mainly Kalanchoe lowers the leaves due to the fact that the plant is freezing. This often happens when overflowing in a cold room. Move the Kalanchoe to a warm, dry room.
If it does not recover, change the soil. Plant the plant in almost dry soil and water only after 1-2 days, when the excess moisture has gone.
Kalanchoe grows upward and does not bloom
A special feature of Kalanchoe is its abundant flowering in the first year of life. So why does the flower then grow upward and not bloom? After the primary flowering, it enters a dormant phase.
Starts stretch upward and does not bloom, accumulate leaves. To make it produce new buds, you need to form a bush.
Cut off the tops and root them. You will get new plants, and old specimens will begin to accumulate strength for budding.
What to do if Kalanchoe stretched out? Remove the top couple of leaves from such shoots. After this, new shoots will grow on them.
Do this until your flower becomes a lush, rounded bush.
To stimulate flowering, they also reduce daylight hours to 12 hours. Put the Kalanchoe in a dark place at 7 pm, and at 7 am put it back in the light.
Why do Kalanchoe have small leaves?
The leaves become smaller and dull due to lack of light. Kalanchoe is needed bright light as long as possible during the day.
This is especially necessary during the period of bud formation and flowering, since at this time it needs a lot of strength. Fertilize once every 14 days.
Chewed leaves
Why does Kalanchoe have nibbled leaves? Sometimes holes appear on the leaves, as if someone had chewed out pieces. These are burns that occur when spraying in direct sunlight.
The drops act like lenses, and the sun burns through the delicate skin. These areas turn into small holes.

Leaf diseases and pests of Kalanchoe:
Pests
Diseases of leaves of flowering Kalanchoe and treatment
Late blight rot
Brown spots indicate infection. Reason - overwatering, poor ventilation.
In addition, this can happen due to a difference in soil and air temperatures of more than 8 degrees.
To prevent this disease from occurring, Kalanchoe should be planted in a loose substrate for good ventilation of the roots.
If disease develops, stop watering.
You can replace part of the soil with new one. It is also necessary to treat with fungicides (Profit Gold, Ridomil)
Gray rot
When it occurs, weeping spots appear on the leaves and stems, covered with gray coating. Like other diseases, gray mold develops when there is an excess of moisture in the soil and air, poor ventilation, and lack of light.
Treatment will help get rid of this systemic fungicides(“Fundazol”, “Rovral”)
Powdery mildew
The disease manifests itself in the form of white spots with a powdery coating, similar to mold on the leaves.
As a result, the leaves die.
The reason for the development of this disease is low humidity and high temperature air.
Under such conditions, the elasticity of the leaves suffers and they become vulnerable to fungus.
To prevent this from happening, you need to follow the watering rules. Spraying with Topaz and Fundazol will help.
Pests of Kalanchoe
Aphid
One of the most dangerous enemies. These are small greenish-black sucking insects that cover the leaves first on the underside. Gradually the entire plant becomes covered with the pest. The leaves begin to lighten and become sticky.
This happens because the aphid secretes a toxic substance. The breathing of the leaves is disrupted, and the plant may die. Aphids also get into flower buds; they do not bloom and fall off.
Infection by aphids is also dangerous because it carries hundreds of viruses. And its secretions are a breeding ground for fungus.
Leaves affected by aphids are cut off and burned. Healthier parts are treated with insecticide. A good auxiliary product is laundry soap. Surfaces are washed with its solution before treating with poison.
But it will not be possible to destroy aphids in one go. Treatment is carried out 4 times at weekly intervals.
Shchitovka
Why do they turn yellow and the lower leaves of the blooming Kalanchoe fall off? This insect is approximately 2 millimeters in size, its body is covered with a brown shell - scale insect.
This coating protects the scale insect from poisons, making it difficult to fight.
Why do Kalanchoe plants dry out and leaves fall off? This happens because the scale insect settles on the underside of the leaves. Thus, they contribute to disruption of their nutrition.
A plaque of insect colonies appears. Plus, sooty fungus grows in the thyroid secretions. This worsens the condition of the plant.
Prevent infection scale insects are possible ventilation of the room and spraying m (scale insects do not like moisture). If the pest does appear, collect it and wash all surfaces with a solution of laundry soap.
Before doing this, wipe them with vodka or alcohol, this will make the scale insects easier to wash off. There are no special poisons produced for this pest, so use any.
What to do if Kalanchoe still dies? Eat folk remedies against this pest. This is an infusion of garlic - 6 cloves per glass of water, infused for 3-4 hours and filtered.
Chervets
Mealybug- sucking insect white. You can notice it with the naked eye.
To the question why the leaves of Kalanchoe dry out, one can answer that the plant is affected by scale insects. It covers the leaves with a waxy coating, the entire above-ground part, and multiplies with enormous speed. A sooty fungus settles on the excretions of scale insects. Kalanchoe affected by scale dries and does not develop.
Prevention against scale insects is cleanliness. Wash and spray Kalanchoe regularly, remove dried leaves.
If you notice the appearance of a pest, take action immediately.
Wash off the scale insects with soapy water and a cotton swab. Then spray the plant three times with an interval of 10 days with infusion of tobacco, garlic, or treat with alcohol tincture of calendula.
If you Kalanchoe leaves dry, this means the plant is severely affected by scale insects, carry out 3 treatments at the same interval with the preparations “Aktara”, Tanrek”, Fitoverm”, “Mospilan”
How to revive Kalanchoe?
If your pet is severely damaged and in this form is no longer pleasing to the eye, it is necessary to restore it. There are several ways:
Pick up optimal place for its existence, follow the care recommendations, avoid damage by insects, and it will thank you with long and very decorative flowering.

The medicinal plant Kalanchoe grows at home for the vast majority of people, regardless of whether the owner is a supporter of floriculture, or grows plants for purely decorative purposes and does not want to devote much time to them, or uses them specifically. Unpretentious and beautiful plant Requires virtually no special conditions for healthy growth and rarely requires care, but may still feel and therefore not look too good if these conditions become unfavorable.
Problems with the plant immediately affect the condition of the leaves; they turn yellow, dry out, and curl. Let's try to determine why the tips of Kalanchoe leaves curl, how to avoid this and save the plant.
Curling leaves indicate problems with the root system, most likely rotting. Most often this happens due to excessive. Although Kalanchoe is a moisture-loving plant, you should adhere to a stable rule: it is better not to add water than to pour a lot.
If the leaves do not just curl, but turn burgundy, then the Kalanchoe is receiving too much light, or even worse, it is in direct sunlight, which is unacceptable.
How to help a plant
After determining the cause of the problem, you can begin to save the plant if it has not suffered irreparable harm. If the cause of the disease is excessive watering, the plant must be removed from the pot and the root system carefully examined. Rotten places are cut off, and the healthy root is washed with a weak solution of potassium permanganate. The cuts need to be treated with charcoal, as always when making cuts on the root, after which the plant should be planted in fresh soil.
Keeping in mind the reason why the damage was caused, watering should be continued less intensively.
If there is a noticeable change in the color of the leaves due to excessive lighting, the plant should be shaded or moved to a less lit place and sprayed with a spray bottle. After some time, the condition of the Kalanchoe should return to normal. If this does not happen, then irreparable damage has been caused and, unfortunately, it will not be possible to save the plant.
Why do Kalanchoe leaves turn yellow? What to do? This query is often entered into search engines by people who are too actively caring for their indoor flowers. Let's look at why this happens.
Improper watering
Most gardeners do not realize that Kalanchoe is a succulent. Water is poured with a generous hand, from the heart and often. They don’t even allow the soil in the pot to dry thoroughly. But the plant is quite capable of doing without watering for quite a long time. And overwatering leads to severe rotting of the roots. And while it is very easy to save a Kalanchoe that has withered due to drought, one that has turned yellow from overwatering is almost never restored.
Signs. The leaves turn yellow throughout the plant, soft, watery. The Kalanchoe itself looks depressed; often the shoots bend under the weight of water inside the leaf blades.
What to do. Urgent rescue! Simply stopping watering, as some sources recommend, will do nothing. Root system has already started to rot. This process must be stopped immediately, otherwise the plant will die.
To do this, remove the Kalanchoe from the pot, then thoroughly wash the roots under running warm water. Now you need to carefully cut off everything rotten, bad-smelling and dark in color. The sections are sprinkled with crushed activated carbon, leave to dry outdoors at least an hour.
After this, the Kalanchoe is transplanted into another soil and a new pot. The old one may contain many pathogenic bacteria.
In the future, the moderation of watering is strictly monitored. Recommended pattern: dried top layer soil in a pot plus another 5 days. By the way, they are not particularly zealous. The soil is only slightly moistened. There is no need to wait for water to flow out of the drainage holes. Kalanchoe doesn't like this. Otherwise, the root system, like a pump, will absorb absolutely all the moisture. And the unknowing owners will start watering the plant again when they see dry soil in the pot. The circle will close and the leaves will begin to turn yellow again.
Incorrect lighting
Signs of lack of light. The leaves turn yellow and become smaller. The shoots become thin and long, like matches.
Signs of too much light. The leaves turn yellow, curl, and dry out. The plant does not bloom.
What to do. Kalanchoe loves bright light. But no more than 10 hours a day. Therefore, there are only 2 outputs:
- Artificially create short daylight hours by covering the Kalanchoe with light-proof material.
- Choose a place of detention where the duration of lighting will be normal. For example, the eastern window sill.
By the way, if the Kalanchoe has already stretched out and turned yellow, then it will not be possible to save the shoots. They will no longer become magnificent compact bush. They will have to be cut off. Just don't throw it away. Such shoots take root well, so why not get a few new plants? These can then be easily formed into a beautiful crown with proper care.
Dry air
The second most common cause of yellowing of Kalanchoe leaves, especially during the heating season. Rarely does anyone think about how hot heating radiators affect a plant.
Signs. The tips of the leaves throughout the plant turn yellow and then begin to dry out entirely.
What to do. Humidify the air around the Kalanchoe as often as possible. You can do this in several ways:
- Spray warm clean water from a spray bottle.
- Place several additional containers with plain water around.
- Cover radiators with wet towels or blankets.
- Place a tray with expanded clay, peat or sphagnum next to it. Water them constantly.
If you do not have the opportunity to provide the Kalanchoe with normal moist air, then it is better to artificially put it into a state of rest. Place in a cool place (+14-16°C), reduce watering. The plant can remain in this position for no more than 2 months, but then you will have to come up with something to increase the humidity. Otherwise, the tips of the leaves will turn yellow.
High temperature
Signs. The leaves turn yellow throughout the plant, look cooked, wrinkled, but not dry. The plant overall looks healthy.
What to do. Stop frying Kalanchoe. It loves bright light, so many gardeners place it on a south or west window. This is quite acceptable, but only in recent years Summer in the middle zone brings incredible surprises. In the sun, the thermometer creeps much higher than +40°C. As a result, the plant is simply fried.
It is imperative to shade the Kalanchoe in the hottest sun. This can be done with white paper or thick light cloth. As a result, the plant will receive enough light, but will not get sunburned. Or better yet, move the pot behind the curtain. For example, on a table or bedside table near the window. Then you won’t have to fence the shading every day.
Natural wilting
Signs. The leaves sometimes turn yellow at the bottom of the stem, gradually dry out and fall off. The plant looks vigorous, grows and blooms well.
What to do. Don't change anything! Your pet is happy with absolutely everything. And the loss of a certain number of lower leaves is normal natural process aging. You should not interfere with the usual microclimate. Kalanchoe feels great.
Wrong fertilizer
Oversupply nutrients just as destructive as a deficiency. Immediately after transplantation, some comrades begin to zealously pour handfuls of fertilizer into the pot. What about Kalanchoe? The root system absorbs everything without complaint. But the leaves refuse to accept such gluttony.
Signs. The leaf blades first turn yellow, then turn brown. A red border and brown weeping spots may appear. The plant looks unhealthy and does not bloom. A large number of loose shoots appear, and the tops may begin to rot.
What to do. Stop eating yourself and stop stuffing the innocent flower. This is a succulent, it is used to living in very harsh conditions. And you give him fertilizer!
Normally, you need to reduce the dose of microelements recommended by the manufacturer by 2 times. Then all this goodness will be useful. Too much is always harmful. Have you ever seen fat people full of health? There are no such things. So why should it be any different with Kalanchoe? Always think before you pour mineral water into your irrigation water.
Advice. To avoid mistakes, use long-lasting fertilizers. Simply place the tablet or granule in the pot. Kalanchoe itself will take as much food as it needs during the next watering.
Pests
Signs. Leaf blades change pigmentation throughout the plant, sticky spots and small dots appear. Then they grow.
What to do. Open your eyes. After all, it is very difficult not to notice uninvited guests on the leaves of Kalanchoe. Insects are very clearly visible to the naked eye, especially on the underside of leaves.
Immediately treat the victim with any systemic insecticide. Just be sure to look for the phrase “approved for indoor plants” on the packaging. And strictly follow the dosage.
It is advisable to quarantine the Kalanchoe for a while so that other flowers do not become infected. If necessary, the treatment is repeated again after about 7-10 days.
Diseases
Excessive watering or too cold air often lead to various diseases. As a rule, owners realize this too late.
Signs. The leaves turn yellow very quickly, then become covered with a bluish coating. Or whitish fluff. The plant withers and then dies.
What to do. Of course, you can try to save the Kalanchoe by spraying it with a fungicide. But even if it recovers, it will look very unpresentable. What beauty is there in a long bald stem with a bunch of crooked, misshapen leaves at the top? Still not a palm tree.
There is only one way out of this situation. You will have to cut as many healthy cuttings as possible to try to root them and grow a new Kalanchoe. As a rule, there are no problems with this; the shoots very quickly gain strength, build up the root system and begin to grow.
And there is no need to grieve over the loss. In any situation you need to be able to see your advantages. But you will have many young healthy plants instead of one sick and shabby poor fellow.
Now you know why Kalanchoe leaves turn yellow. What to do? - also aware. Therefore, you can provide your pet with decent living conditions at home and without yellowing. And he will thank you with lush green foliage and fabulous flowering.

Why does it wither
Kalanchoe is a succulent plant and therefore very easy to care for. But if the care is not correct, some problems may begin. For example, the flower will take on an unsightly appearance and will have limp leaves. They will be soft in consistency, and if nothing is done, the leaves will soon fall off.
The following points can lead to such a situation:
- overwatering the plant. Kalanchoe is capable of accumulating water to some extent in its leaves. That’s why they look fleshy and dense near the flower. And if you flood the plant, the leaves will begin to fall;
- insufficient watering. Of course, Kalanchoe can remain without water for some time (even an earthen crust may appear in the pot), but if watering is insufficient, the leaves will dry out. During prolonged drought they fall off;
- water indicators. “House Doctor” should be watered with settled and soft water. Otherwise, various diseases and other manifestations of poor health of the flower may appear;
- light mode. For some varieties of Kalanchoe, a negative factor for growing at home is exposure to direct sunlight on the leaves. In this case, the leaves may curl and appear brown spots, which indicate a sunburn of the leaf blade has occurred;
- temperature regime. When creating the wrong temperature regime the leaves of the plant also begin to dry out and fall off.
It is very important to properly monitor the flower during the dormant period and in winter. In this situation, even slight fluctuations in the parameters described above can lead to the leaves beginning to fall and the plant itself to become sick.
Also, yellowing of the leaves occurs after the end of the flowering period and indicates depletion of the plant. Here the leaves fall from below, thus exposing the stem, which begins to stretch. During this period, the flower is most susceptible to the influence of pathogenic microorganisms. To avoid this, it is necessary to fertilize Kalanchoe immediately after the end of the flowering period.
If the leaves dry out, this indicates a lack of micro- and macroelements (for example, boron). To restore proper nutrition, you need to do additional feeding of the plant. Why a flower withers can be answered differently depending on its age. In young plants, improper watering is often the reason for the appearance of spots on the leaves, which leads to their falling off. The sluggish appearance of the flower indicates insufficient or irregular watering. In this situation, you only need to do one thing - normalize proper watering.
But for old plants, this condition may be a consequence of the natural aging process. There is no need to do anything in this situation, since Kalanchoe can no longer look different for natural reasons.
This is why homemade Kalanchoe withers. But this is only part of the reasons. To the question “why does the plant wither?” You can give a completely different answer - the plant began to hurt. When a flower sheds its leaves, the first thing you might think of is disease. And only then about the fact that caring for him was incorrect. If the plant begins to hurt, then the first symptoms will be a sluggish appearance, small and underdeveloped leaves, as well as the appearance of various spots on them.
The reason why is this house plant started to hurt, you should also look for care. A very common cause of disease development in domestic Kalanchoe is overwatering. The root system of succulents is very sensitive to moisture and if there is too much moisture, the roots begin to rot. As a result, a favorable environment is formed for the development of many pathogenic microorganisms, as well as insect pests.
As you can see, the reasons why the “house doctor” withers can be different. But the most important parameter that you should think about first when the Kalanchoe leaves begin to fall off is improper watering.
Diseases
If improperly cared for, Kalanchoe at home becomes susceptible to various types diseases. External manifestations of flower disease can be different. In case of illness of this plant Black spots and even mold may appear on its leaves. At the beginning, the spots will be small, and then they will begin to increase in size. The appearance of spots on the leaves indicates that the Kalanchoe has been infected by a fungus. To get rid of it, it is necessary to completely spray the plant with fungicides.
The main reason for the appearance of fungus and black spots is severe waterlogging of the soil, as well as a violation of its aeration. Therefore, it is not enough to simply spray the flower with fungicides; you also need to transplant the plant into another pot with new soil.
In addition, brown spots may appear on the leaf blade. Their appearance indicates the presence of a disease called Dropsy. It develops with a combination of waterlogging and temperature changes. To get rid of this disease, you need to move the pot to a drier and warmer place, and also reduce the number of waterings. Sometimes you can notice a white coating on the plant. This means that watering was carried out with too hard water with a high content of lime and salts.

Kalanchoe, in addition to the conditions described above, can also be subject to the following diseases:
- late blight rot. When it occurs, brown spots form on the leaves. The reason for the appearance is poor ventilation, temperature changes between soil and air, or excessive watering. To combat the pathogen, you need to eliminate negative influencing factors and treat the flower with fungicides;
- gray rot. As this disease develops, weeping spots appear on the stems and leaves, which are always covered with a gray coating. The main reasons for the appearance are excess moisture, insufficient light conditions and poor ventilation. The means of control are the same as for late blight rot;
- powdery mildew. This disease manifests itself in the form of white spots with a powdery coating. Outwardly, they resemble mold. As a result of this disease, leaves fall from the stems. The causes of the disease are considered to be high air temperature and low humidity.
As you can see, improper care of the “house doctor” can lead to its infection with fungal microorganisms and treatment will be required to avoid death.

Pests
Kalanchoe is often grown at home and is rarely attacked by pests. But if the care is improper, the plant can become a container harmful insects.
Let's look at each pest in more detail.
Aphids are the most dangerous enemy for Kalanchoe. Aphids are small greenish-black sucking insects. It initially lives on the underside of the leaf and eventually spreads throughout the plant. In the presence of such a pest, the leaves begin to lighten and become sticky to the touch. This is the result of the action of aphids, which secrete a toxic substance. In this case, Kalanchoe does not bloom, and the buds that appear wither and fall off.
The danger of infecting flowers with this particular insect is that the aphid becomes a carrier of many viruses and creates optimal conditions for the development of the fungus. The fight against it involves destruction by burning the affected stems and leaves, as well as treating healthy parts with an insecticide. It will not be possible to destroy aphids in one go. A minimum of 4 treatments are required at one week intervals.

Scale insects are less dangerous for Kalanchoe. This is a small insect (2 mm in length) with a scale insect that covers its entire body. Settles on the underside of the leaf, forming colonies. A sooty fungus develops in the secretions of this insect. If it appears, then the surface of the leaves and the flower should be treated with a solution of laundry soap.
The scale insect or RјSѓS‡РЅРёСЃС‚ый червь has a white appearance and is clearly visible on a green leaf. As a result of its activity, the leaf becomes waxy. Promotes the development of sooty fungus. To prevent it from appearing, spray the plant regularly.
How to revive a plant
To revive Kalanchoe, you need to do the following things:
- organize proper care;
- eliminate pests or pathogenic microorganisms;
- pinching;
- apply fertilizers;
- observe optimal humidity, light and temperature conditions.
All these manipulations will help you restore the plant after illness or insects on it. This is the only way Kalanchoe will delight you with health and beautiful flowering.

Hello! Please tell me: my Kalanchoe leaves are curling, what does this mean and how to fix it?
Vadim, in winter, Kalanchoe should rest in bright light and coolness, with virtually no watering and no fertilizing at all. Natalia. an adult - yes, will survive the winter in rest...... and a small one? Is he strong enough? Maybe feed it before winter? Or leave it like that? Thank you.

How to determine the cause
It is difficult to answer unequivocally the question why the leaves of your medicinal Kalanchoe curl. There are several reasons for this phenomenon, but all of them can be easily eliminated. First of all, you need to carefully examine the soil where Kalanchoe grows. If there is too much nitrogen in the soil, then most likely this fact contributed to the curling of the leaves.
Lack of moisture is another likely cause. Not only the soil, but also the leaves should be moistened. It is advisable to maintain normal humidity in the room where the flower is located.
But the most common factor why Kalanchoe leaves curl is the presence of harmful insects. Aphids cause enormous damage to flowers. It sucks the juice from the leaf, causing the death of the plant. At first the leaves curl and then fall off. It is noteworthy that aphids most often appear in spring time when Kalanchoe begins to bloom.
How to save a flower
Once you have found out the reason that the Kalanchoe leaves are curling, you should take measures to save it. Of course, if irreversible processes have not begun. If the twisting occurs because you overdid it with watering, then the plant should be carefully removed from the pot and the roots inspected.
All rotten areas should be removed, and a healthy root should be treated with a weak solution of potassium permanganate or potassium permanganate. Treat the areas where the cut was made with charcoal. After all these simple procedures, place the plant in a pot, replacing the soil with fresh one. Now don’t repeat your previous mistakes and don’t be too zealous with watering.
If the leaves noticeably change color and the reason is bright lighting, then move the plant to a more shaded place and spray it with a spray bottle. A few days are enough for the plant to recover. If this does not happen, then, alas, irreparable damage has been caused to the plant, and despite treatment it is not possible to save it.
We have already found out that insects cause great harm to Kalanchoe, which leads to the fact that the leaves begin to turn yellow and curl. If you find areas on the plant damaged by aphids, immediately cut them off and burn them. The remaining plant must be treated with an insecticide for indoor plants. It should be processed once a week for 30 days. Another first aid technique is to wash the flower with a solution of green potassium soap or you can use laundry soap. A nuance: during processing, to prevent the product from getting on the ground, it is wrapped in polyethylene.
Scale insects also cause damage to the plant. The condition of Kalanchoe worsens because sooty fungus multiplies in the sticky secretion secreted by the scale insect. To save the plant from troubles, you need to collect harmful insects from the leaves and wash the plant with soapy water. You can make it easier to remove insects by pre-treating the plant with alcohol. Since there are no separate preparations to combat scale insects, you can treat Kalanchoe with any insecticide for house plants.
Another folk method: remove insects from the leaves using an old toothbrush and spray with garlic infusion. To prepare a medicinal infusion, you need to crush 5 cloves of garlic in a mortar, add water and leave in a dark place. After a few hours, the infusion is ready, all that remains is to filter it.
If a flower is affected by gray rot, then it should be treated with fungicides, the soil should be replaced and placed in a bright place.
With defeats powdery mildew fight by spraying with fungicides and providing regular but not frequent watering.
As you can see, if you find out in a timely manner why the green leaves of Kalanchoe are curling and take appropriate measures, then almost all diseases are curable.
Prevention
It is easier to prevent any disease than to treat it. Therefore, in order not to give Kalanchoe leaves Wrap up, you need to follow the care recommendations and take preventive measures to control pests.
First of all, you need to rid the plant of drafts, sudden temperature fluctuations, and frequent changes of place of “residence”. Watering should only be done with settled and not very cold water. Do not overdry the flower and allow the plant to receive excess heat, which will lead to weakening.
Keep the plants clean, remove fallen leaves, and you will not give unnecessary reasons for pests to appear.
Another preventive measure is compliance with the light regime and watering schedule.
Inspect the flower regularly for pests. If detected, immediately begin to fight them. Remove the insects and spray the Kalanchoe with a fungicide or insecticide.

Kalanchoe dries: why it appears yellow leaves? Read in today's article about the reasons why Kalanchoe leaves dry out and fall off? Basic ways to restore Kalanchoe.
Kalanchoe can be:
- Do not water for a long time;
- Almost no feeding;
- Place anywhere;
Then why do most flower growers complain about problems with leaves – they turn yellow, dry out, and fall off. Excluding natural stages life cycle, we suggest immediately determining for what reasons the leaves of Kalanchoe dry out and fall off.
We would like to point out right away that Kalanchoe reacts differently to sunlight. Leaves may dry out on the upper tiers due to insufficient lighting, but they may also turn yellow along their entire length, which will indicate an excess of sunlight in the room. Place the Kalanchoe so that the room is flooded with light, but the plant is not clearly in the path of the sun's rays. The length of daylight hours and the volume of lighting increase gradually with the arrival of spring. 
In early spring, Kalanchoe is exposed to new weather conditions, so moderate watering and gentle feeding is required. From mid-spring you can spray leaves, apply fertilizer to spilled roots and water with settled water, but for now leave the flower to calmly adapt - he is like an owl person by temperament at 5 in the morning, who does not yet understand what they want from him.
How to fertilize Kalanchoe: potassium + phosphorus.
Pests on the plant, of course, need to be killed, quickly and accurately. Insecticides and acaricides will help with this: "Aktellik", "Dichlorobiphenyl", "Fitoverm". Treat Kalanchoe according to the instructions, in a well-ventilated area, do not come into contact with the solution and do not inhale its vapors.
Kalanchoe diseases: spots, mold, powdery mildew, fungus on stems and leaves, dropsy. When a disease is detected, the affected part is immediately cut off, then the cut site is treated with fungicides, for example “Acrobat”, and the rest of the plant after a few hours is spilled or sprayed with a lightweight version.
Since no disease occurs without a cause, it is necessary revive Kalanchoe due to the normalization of care: restore the air temperature, which, in all likelihood, affected the flower spasmodically; place in the same moderately lit place; do not overfill or feed, but do not forget that these are basic and necessary procedures; control air humidity; water with soft water without chlorine or salt impurities.
The main ways to revive Kalanchoe:
- Eliminate the acute cause using medications;
- Carry out complex therapy for recovery;
- Trim affected areas;
- Normalize home care and related criteria;
- Continue to care for Kalanchoe moderately and unobtrusively;

Kalanchoe diseases: treatment at home
Late blight rot
Poor soil breathability, associated with waterlogging, leads to rotting of the roots. Soil pathogens such as late blight exacerbate the problem.
Late blight is dangerous for many plants, appearing the same everywhere Symptoms of late blight fungal infection:
- growth slowdown;
- soft stem near base;
- brown spots in the branching area;
- As the disease progresses, a moldy smell appears.
What to do: prevents the development of late blight rot by replanting Kalanchoe in a permeable, sterile environment. This is a soil containing peat moss and perlite. ( 60:40 or 50:50).
If using an old pot, disinfect it in a 10% bleach solution (1 part bleach - 9 parts water). Phytophthora does not survive in dry tissue, but forms dormant spores that survive for long periods without a host plant.
When soil moisture and temperature conditions are favorable, its development increases and can reach invasive levels.
Should not be left in the tray standing water which flows out through the drainage holes. The roots are able to reabsorb it. Treating the soil with a fungicide (thiophanate methyl) helps control the fungus.
Methyl thiophanate can help with soil contamination with fungus However, chemicals are effective only if the damage to the root system is not too extensive.
Thanks to this method, the flower less susceptible to infection late blight. Significant suppression of symptoms is observed when treated with salicylic acid and silicon or chitosan.
We have already described negative impact diseases on specific varieties of Kalanchoe. For example, how late blight manifests itself and is treated in Kalanchoe kalandiva.
Gray rot
Causative agent of gray mold– pathogenic (necrotrophic) fungus Botrytis gray. The main factors for its appearance are high level humidity and cold ambient temperature.
Symptoms:
- wet whitish spots form on the leaves;
- over time, the spots change in color: grayish growth, which contains spores (reproductive cells) of the fungus;
- the fabric becomes soft.
Once the disease is detected, it is urgently necessary change conditions of detention Kalanchoe. Remove infected areas. Clean the plant with systemic fungicides. Take care of good lighting. You may need to change the soil.
A fungal disease that affects a wide range of plants, including Kalanchoe. It is easily recognizable because the symptoms are very peculiar:
- small chlorotic spots on leaves;
- as it grows, the fungal mycelium covers increasingly larger parts of the plant, appearing as a dusty white or grayish-silver web;
- black or brown spots(fungus fruiting body) on the mycelial surface;
- growth slows down due to impaired photosynthesis, buds do not ripen;
- curling and falling of the integument (an atypical brownish symptom resembling scab may occur).
Powdery mildew is a fungus that attacks any plants: indoors and outdoors. Conditions favorable to the development of the disease:
Treat with fungicides (benomyl, fenarimol), sulfur-based, neem oil, potassium bicarbonate. The selected product is applied both to the stem and to the axils of the leaves.
A product that has proven its effectiveness and is even comparable to some fungicides - milk diluted in water(1 part milk to 10 parts water). It is good to use at the first sign of infection or as a preventative measure.
The mechanism of action is ferroglobulin. This whey protein when exposed sunlight produces oxygen radicals, upon contact with which the fungus dies.
Pests: what to do
Aphids: how to stop blooming and dropping flowers
At the initial stage of infection, any signs of aphids are difficult to detect. The insects are so tiny and located on the back of the leaf that go unnoticed.
The danger of aphids is that they quickly move to neighboring plants. The colony is discovered during reproduction. It has been noticed that aphids quickly reproduce on full-fledged Kalanchoe flowers.
The pest drinks the cell sap and constantly contaminates it with poisonous injections.
Symptoms:
- the plant is polluted and deformed;
- leaves turn yellow;
- the buds don't bloom, drops real flowers;
- the affected parts and the stem are covered with sticky matter.
The scary thing is that aphids are carriers of more than 100 types of viruses. The insect needs to consume huge amounts of juice because the concentration of sugar is too high relative to the concentration of amino acids.
The pest deposits sugar in the form of a sticky secretion on the leaves and stems of plants, which attracts ants and serves as a nutrient solution for fungi. This “nectar” clogs the respiratory pores (stomata), interfering with the plant's ability produce its own nutrients.
To get rid of aphids, Kalanchoe is treated with an appropriate insecticide. Treatment is repeated once a week for a month.
Recommended green soap solution(20 g of soap per 1 liter), which is used to wash the plant, having previously covered the soil with polyethylene. Alternatively, use a solution with laundry soap: It also harms aphids, but to a lesser extent.
But the first thing to do is:
Aphids are attracted to Vaseline, which can be rubbed at the base and thus control the population.
Shchitovka
Tiny bugs that resemble brown or orange discs or blobs can be found on the underside of the leaves near the veins, on the stem, at the junction of the leaf and the stem.
The scale insect has only one advantage - it is easy to notice This "nectar" attracts sooty mold growing on leaves. In general, the process is not that fast, often taking many weeks before you notice that the plant has become a target for the pest.
How to save: Products containing the following chemical ingredients are effective for control:
- pyrethrum;
- natural fatty acids;
- rapeseed oil.
For prevention Check regularly for signs of scale infestation. The soil should be free of weeds, which often contain pests. Ants running up and down and “milking” the sticky secretion is an important signal.
Mealybug
Tiny, oval shaped, with a powdery waxy coating mealybugs look like cotton specks, which are often mistaken for mold. They move slowly, but when they find it for themselves suitable place, then become motionless and form clusters.
When attached to a plant, they secrete a sticky substance that they use for protection, while absorb plant juice.
Mealybugs are as easily identified as scale insects The damage caused by mealybugs is not immediate, but is destructive over time. As with any pests of indoor plants, treatment must begin immediately as soon as the problem is discovered.
Not recommended use synthetic pesticides, because mealybug resistant to most chemicals. In addition, it develops resistance to pesticides that are used on a regular basis.
It is best to use safe methods:
- Using a cotton swab well soaked in alcohol, remove insects from the flower.
- Spray on the leaves of an infected flower organic insecticidal soap or a solution of soapy water (at the rate of 1 teaspoon of baby liquid soap per 1 liter of water).
- If the plant is young, it is easier to wash it under running water or under the shower with soapy water.
In this case, you will also need a product to get rid of ants. This is very important because ants protect these pests and move their waste from one plant to another.
Diagnosis of symptoms: questions and answers
Doesn't bloom, only produces foliage
The reason is that Kalanchoe does not bloom, despite the fact that the leaves are succulent and healthy, maybe in excess of fertilizers. Kalanchoe is a short-day plant and blooms depending on how long it is in the dark.
If it is exposed to sunlight every day for more than 12 hours, it may not bloom.
Why do the leaves curl?
Kalanchoe is sensitive to thrips, cyclamen mites and leaf rollers, which cause curling. If this is the problem, then treatment with an insecticide or miticide will be needed.
The fact is that Kalanchoe is rich in flavonoids, which are considered protective against UV.
Ultraviolet radiation negatively affects the health of the flower, causing painful symptoms. Appearance of black spots
Most likely, it is caused by a fungal disease. This means that Kalanchoe is suffering from low temperature and excess humidity.
In addition to being unsightly, black spots can cause damage at the cellular level, resulting in leaf drop (defoliation).
The appearance of black spots may be a sign of a secondary complication, for example, after a mealybug infestation.
Brown spots on leaves
Formed as a result of dropsy (edema) or fungal infection. The best way to keep the leaves healthy is to avoid getting them wet. Although succulent leaves are thick, fleshy, and filled with sap, it is does not mean that Kalanchoe needs to be watered more often than other plants.
On the contrary, the soil should dry out between waterings. Kalanchoe is sensitive to excess fertilizer and usually needs rare and diluted supplements (light fertilizer once a year).
If there is an excess of salts contained in the fertilizer, they accumulate in the soil and can burn the roots. And as the salt solution moves upward, it affects the leaves, causing formation of brown spots.
White coating on leaves
Powdery mildew prefers the same type of habitat as Kalanchoe: warm, relatively dry areas. It may seem harmless at first and the plant may even thrive for some time.
Leaves fall: causes and care
The reason is most likely in the weakness of the plant. In the cold season this happens due to the proximity to central heating. Most likely, the plant is on the windowsill near the radiator, and the air around it is too dry.
It is better to move your pet to a room with a lower temperature according to the following recommendations:
Leaves turn yellow and dry out
All flower growers dream that Kalanchoe will always please the eye with green leaves. But it happens that the stem stretches, the lower leaves begin to turn yellow and dry out. These problems indicate improper lighting.
Direct sunlight can be harmful to indoor plants Kalanchoe prefers bright indirect light for summer period, respectively eastern or western exposure. During winter, the plant needs more light, so it is better to move it to a southern exposure.
The flower withers
Sometimes this problem occurs after flowering, when the plant begins to deplete. To stop: urgently needs replanting or feeding with fertilizers.
How to help Kalanchoe bloom
As the days get shorter and the Kalanchoe experiences long periods of darkness, more flowers appear on the plant. But flowering can be induced by simulating darkness for six weeks.
Try imitating dark conditions to make Kalanchoe bloom Between October and early March, the days are short and the buds appear naturally. At other times, the plant is placed in the dark and left for 14 hours every day and in daylight for 10 hours.
Home watering is reduced by half. Optimal temperatures for the formation of flowers - 7 degrees at night and 16 degrees during the day. Kalanchoe will bloom in 5-7 weeks.
After which regular care is resumed. Withered flowers are removed, stimulating the appearance of new ones.
Kalanchoe prefers warm temperatures– between 15 – 25 degrees. At low temperatures(less than 4 degrees) the plant may die within a few hours.
Keep plant leaves dry and provide well-drained and aerated soil. To get a blooming specimen, you need to remove the flower into the house in a timely manner.
Although Kalanchoe is considered a medicinal plant, its flowering looks very beautiful In summer it can be taken outside in a slightly shaded place, and return indoors before the first frost or 3 months before the desired flowering time. Although you need to remember that outdoors the plant attracts ticks, scale insects and aphids.

Kalanchoe care and possible diseases
Any plant requires daily care, even such a picky one. If you neglect simple rules, then in most cases Kalanchoe may get sick or die. You need to know that bright light is not suitable for this indoor flower, as well as abundant watering. Only if such moments are observed, a flower can bloom and delight for a long time.
The main diseases and pests are as follows:
In fact, the occurrence of such a phenomenon in a plant can be explained by several reasons that are easy to eliminate. First of all, you should pay attention to the soil in which Kalanchoe grows. High nitrogen content in the soil can contribute to unpleasant phenomena such as leaf curling and yellowing. The ideal option for the plant is soil containing a large amount of sand.
The next reason may be lack of moisture. To avoid this, you need to carefully monitor the regular watering of the plant, or additionally spray it with a spray bottle.
However, the most common factor affecting the appearance and condition of the plant is the presence of insects. So, for example, aphids can cause enormous harm to Kalanchoe. By sucking the juice from the plant, these harmful microorganisms provoke the death of Kalanchoe. Its leaves begin to turn yellow and curl, and then fall off. If areas damaged by aphids are found, they should be cut off and disposed of immediately. It's best to burn it. And treat the plant itself with special disinfecting solutions. Aphids most often appear in the spring, when trees are flowering. The task is to detect it in time and promptly stop the process of plant death.
poleznaya-trava.ru
Aphids, mealybugs, and scale insects are the main pests of Kalanchoe. The insects feed on succulent leaves by piercing their tentacles and drawing out cell sap like a hypodermic needle. Let's consider why a plant may not bloom or produce foliage, but turn yellow and darken.
Late blight rot

Late blight is dangerous for many plants, appearing the same everywhere Symptoms of late blight fungal infection:
- growth slowdown;
- soft stem near base;
- brown spots in the branching area;
Mature leaves wither (if most the plant has withered, then most likely the rot has completely affected the roots and it is extremely difficult to preserve it).
- As the disease progresses, a moldy smell appears.
What to do: prevents the development of late blight rot by replanting Kalanchoe in a permeable, sterile environment. This is a soil containing peat moss and perlite. ( 60:40 or 50:50).

Methyl thiophanate can help with soil contamination with fungus However, chemicals are effective only if the damage to the root system is not too extensive.
Biostimulating products are used for prevention. The addition of salicylic acid causes upregulation of genes important for the production of jasmonic acid.
Thanks to this method, the flower less susceptible to infection late blight. Significant suppression of symptoms is observed when treated with salicylic acid and silicon or chitosan.

After which regular care is resumed. Withered flowers are removed, stimulating the appearance of new ones.
Kalanchoe prefers warm temperatures– between 15 – 25 degrees. At low temperatures (less than 4 degrees) the plant may die within a few hours.
The best way to prevent Kalanchoe diseases is to follow simple conditions.
Keep plant leaves dry and provide well-drained and aerated soil. To get a blooming specimen, you need to remove the flower into the house in a timely manner.

Kalanchoe is considered one of the most unpretentious plants. It is easy to grow at home. Therefore, this representative of the flora can be seen in almost every home. Useful properties Kalanchoe has long been used in medicine. It is for this reason that most flower lovers breed this flower Houses. Caring for Kalanchoe and possible diseases Any plant requires daily care, even such a picky one. If you neglect simple rules, then in most cases the Kalanchoe may get sick or die. You need to know that bright light is not suitable for this indoor flower, as well as abundant watering. Only if such moments are observed, a flower can bloom and delight for a long time. There are many parasites that can harm not only the appearance of the plant, but also its vital activity. Let's take a closer look. The main diseases and pests are as follows: Light, round spots on the leaves that resemble rings - this phenomenon is called ring spot and is caused by a virus. Young leaves are too light color, and older ones take on a rough, unaesthetic appearance. This phenomenon is called abnormal growth virus. Flower petals become dark green and do not grow in length. Scientifically called flower gardening. White discharge in the leaves indicates the presence of scale insects. If there is a very strong downward inclination of the stems and leaves, then most likely the plant has parasites called mites. A white coating on leaves and stems is usually caused by powdery mildew. Too soft, watery leaves - gray rot. The presence of small yellow spots on the leaves indicates the presence of mites. Black spots large size, sometimes bulging plants on the stem indicate stem rot disease. The sudden death or rotting of a plant from the stem to the roots is late blight. Yellowing of the leaves and curling symbolize the presence of aphids on the surface of the plant. The main reason for the curling of leaves in Kalanchoe In fact, the occurrence of such a phenomenon in a plant can be explained by several reasons that are easy to eliminate. First of all, you should pay attention to the soil in which Kalanchoe grows. High nitrogen content in the soil can contribute to unpleasant phenomena such as leaf curling and yellowing.
