Kalanchoe leaf disease and treatment

4 Errors in watering

Often, Kalanchoe leaves turn yellow and dry due to improper watering. Like any succulent, Kalanchoe does not like excessive watering.

General recommendations for proper watering:

  • water with settled water at room temperature;
  • water more abundantly in the summer;
  • reduce the amount of water and increase the intervals between waterings in winter;
  • in hot weather, no more than 1 time a week, it is permissible to spray the plant with boiled or purified water so that no lime stains remain on the leaves.

Kalanchoe with yellowed leaves could suffer from watering from the tap without settling. This is extremely harmful - the chlorine contained in the water negatively affects the general condition of the plant and, over time, can lead to its death. Therefore, tap water must first be kept in an open container for at least 24 hours so that the chlorine can “disappear”.

At first, when caring for the Kalanchoe, it can be difficult to determine whether the flower needs to be watered or it is too early. Experience will come with time, but at first it is worth focusing on one watering per week during flowering and a little less often during dormancy. In winter, Kalanchoe is watered 1-2 days after the earthen lump dries out.

Attention! If Kalanchoe has yellow leaves, most likely there is not enough moisture, and watering needs to be increased. The presence of lethargic yellowed leaves indicates an excess of liquid in the soil.

In this case, you need to let the ground dry, and then water more carefully. If suddenly, for some reason, the plant has been without watering for a long time, you should not pour the usual rate of water into a flower pot with a generous hand.

After a long drought, the Kalanchoe should be gradually "accustomed" to moisture, each time increasing the volume of liquid to the usual

If suddenly, for some reason, the plant has been without watering for a long time, you should not pour the usual rate of water into the flower pot with a generous hand. After a long drought, the Kalanchoe needs to be gradually "accustomed" to moisture, each time increasing the volume of liquid to normal.

Why do hovea leaves turn yellow

In the wild, hovea lives in the subtropics. But you should not rush to create too warm conditions for the plant and put the pot next to the battery. This will definitely lead to yellowing of the foliage. The main reason for such changes is the air humidity that is unsuitable for the palm tree. Following the loss of leaves, it will stop growing and wither, and then completely die. Humidity for hovei should be at least 65%.

Such parameters can be achieved in several ways:

  • spray the plant and the area around it regularly, at least once every 2 days;
  • install several containers of water near the flowerpot;
  • buy a humidifier or decorative fountain.

As soon as the humidity in the room returns to normal, the palm will turn green again. Also, the reason for the yellowish tint of the leaves may be a lack of nutrients in the soil or an excess of calcium, which occurs when the plant is watered with hard water. Therefore, it is better to use well-settled, filtered or melt water.

Pests on kalatea

If we talk about the indoor flower calathea, pests in the form of parasites are most often found due to various problems in the care and growing of the plant:

  • Spider mite. Symptoms of the parasite are white bloom on the back of the leaves. Over time, a cobweb becomes noticeable on the plant. The tick is very small and difficult to see. The leaves first turn yellow, and then they begin to fall off. The pest prefers dry air, so the flower must be sprayed frequently.In addition, mechanical treatment is carried out with an insecticidal agent.
  • Shield. Upon infection, small round plaques appear on the stem and leaves. Over time, the leaves turn pale and dry out. The plant can be cured if it is treated with a solution of laundry soap. To consolidate the results, it is necessary to spray with Fitoverm.
  • Thrips. Small dots appear on the leaf plate, which gradually turn into spots. On the soil, small oblong insects are noticeable, which move in leaps and bounds. If parasites are found, it is necessary to rinse the plant under the shower and spray it with Intavir. To fix the result, you can repeat the spraying two times. The same solution is used to treat the soil in which the flower is located.

Signs of plant damage by aphids

With early detection of pests, it is not difficult to deal with them, since there are many insecticidal and folk remedies.

Calathea (home care, illness, treatment are described above) is an attractive shrub that is often used as a decorative decoration. When the leaves of a calathea flower curl, every grower should know what to do. The plant requires increased attention to itself, and it must be grown taking into account all the rules.

Examples of flower treatment at home

Kalanchoe has medicinal properties and is often used in alternative medicine to treat diseases of the upper respiratory tract, sore throat, inflammation of the adenoids, damage to the upper layers of the epidermis, etc.

Interesting. To treat a cold with Kalanchoe, you should mix the juice of the plant with water in a 1: 1 ratio. This solution is dripped into the nasal passages 3 times a day. Within a few days, the runny nose disappears.

For acute respiratory diseases 1 tsp. the juice of the plant is mixed with the same amount of honey. The resulting mass must be eaten 2 times a day.

Alcohol tincture with Kalanchoe juice will help reduce joint pain. For this, the ingredients are mixed in a 1: 1 ratio. The resulting mixture is rubbed on the joints several times a day.

Soil depletion, improper feeding

In the absence of a transplant, the root system grows, it becomes cramped in the old pot. In addition, a gradual depletion of the soil occurs, as a result of which the Kalanchoe begins to experience a deficiency of nutrients. In this case, the growth of the flower is suspended, the leaves become smaller and turn yellow.

Young bushes are transplanted annually, the soil in pots of adult plants is changed every 2 years. If the Kalanchoe is still actively growing, the planting capacity is chosen 1.5-2 cm wider and deeper than the previous one.

It is advisable to take a commercial soil mixture intended for succulents, since it has a balanced composition. The drainage layer is made of any suitable material (pebbles, expanded clay, brick chips) with a layer of at least 1 / 5-1 / 4 of the depth of the pot.

Succulents are sensitive not only to a lack, but also to an excess of nutrients, so they feed them very carefully. Fertilize mainly flowering species from late spring to early autumn

Top dressing is carried out no more than 2 times a month with compositions for succulent plants. The concentration of the solution is made 2 times weaker than that recommended in the instructions.

Lack of fertilizer and other reasons

All potted plants need periodic fertilization. The soil in a pot does not undergo natural enrichment, and therefore tends to deplete. Fertilizing the plant during active growth allows not only to achieve vigorous flowering and the formation of beautiful buds, but also contributes to the proper nutrition of the plant. Lack of nutrients can just be the reason why the leaves of the Kalanchoe turn yellow. And the solution to the problem is one thing - you need to apply fertilizers.

If the plant lacks nutrients, the state of the leaves can be used to understand what elements it needs.

  • if the edges of the leaves are brown, this is a symptom of a lack of boron;
  • slow plant growth, too small leaves - lack of nitrogen;
  • the appearance of spots on the leaves and the death of shoots indicate a lack of molybdenum;
  • yellowed, wrinkled, fallen and dying bottom layer of leaves indicates an excess of phosphorus.

Over-fertilized soil also affects the plant in a bad way. You can understand about an excess of fertilizers by the dried tips of the leaves and white bloom on the surface of the earth. It must be removed and poured fresh. Brown tips on leaves and other plant appearance problems may indicate the following:

  1. 1Even if the hostess watering the Kalanchoe correctly, a typical mistake is watering the plant with ordinary tap water. Such water contains chemicals that have the risk of scorching Kalanchoe leaves. Therefore, it, and other indoor plants too, must be watered with water, which must first be defended for several days.
  2. 2If the indoor air is excessively dry. This situation often arises in winter if the flower pot is located in the immediate vicinity of the radiators. In this case, it is enough to remove the flower from such a place, and no longer place it near heating systems and appliances. It must be remembered that the winter increase in watering will not cope with the problem of dry air, but will only aggravate it, causing root decay. You can use gravel, a humidifier, and you can also put a flower in the kitchen. But again, there should not be a heating battery under the windowsill, since the temperature difference - the cold comes from the window, and the heat from the battery - can cause the leaves to dry and curl.
  3. 3If Kalanchoe leaves dry, curl and fall off in summer, and the flower is outdoors, for example, on a balcony, aphid infestation may be the cause of the problem. To save a flower, you need to bathe it in soap suds, cut off the infected areas and treat it with nicotine sulfate.
  4. 4 Weeping brown spots are a symptom of a plant infection with a viral or bacterial infection. In this case, all infected leaves should be removed, and the Kalanchoe itself should be treated with phytosporin. After that, it will be necessary to reduce watering for a while and stop spraying the leaves.
  5. 5Sometimes, not only the leaves dry out, but the entire stem of the plant. In such a case, there is a high probability of infection of the root system with parasites that feed on plant juices. The same is indicated by the appearance of small defects, sticky spots and other painful conditions on the leaves. With a strong infection of the plant with parasites, as well as with a strong flood of soil, the Kalanchoe must be transplanted.
  6. 6 Do not forget that watering the succulent should be moderate and gradual. You can not flood the plant with water, even if before that it stood in dry soil for a long time.

Kalanchoe pests

If the leaves turn yellow on the Kalanchoe or other problems appear, attacks of dangerous pests can be suspected.

Schervets

The mealybug is a white sucking insect. You can see it with the naked eye.

When asked why Kalanchoe leaves dry, one can answer that the plant is affected by a worm. It covers the leaves with a waxy coating, the entire aerial part, multiplies at a tremendous speed. A sooty fungus settles on the secretions of the scale insects. Kalanchoe affected by the worm dries up and does not develop.

The prevention against worms is purity. Wash Kalanchoe and spray regularly, remove dried leaves.

If you notice the appearance of a pest, take action immediately.

Wash off the worms with soapy water and a cotton swab. Then, three times with an interval of 10 days, spray the plant with infusion of tobacco, garlic, or treat with alcohol tincture of calendula.

If the leaves of the Kalanchoe dry up, then the plant is heavily affected by worms, carry out 3 treatments with the same interval with the preparations "Aktara", Tanrek ", Fitoverm", "Mospilan"

Shield

Why do the lower leaves of the flowering Kalanchoe turn yellow and fall off? This insect is about 2 millimeters in size, its body is covered with a brown shell - a scabbard.

This coating protects the scabbard from poisons, so it is difficult to fight it.

Why do Kalanchoe leaves dry and fall? This is because the scale insect settles on the underside of the leaves. Thus, they contribute to the disruption of their nutrition.

Plaque appears from insect colonies. Plus, a sooty fungus starts in the secretions of the thyroid gland. This worsens the condition of the plant.

You can prevent infection with the scabbard by airing the room and spraying (the scabbard does not like moisture). If the pest does appear, collect it, wash all surfaces with a solution of laundry soap.

Before that, wipe them with vodka or alcohol, so the shield is easier to wash off. Special poisons are not produced from this pest, so use any.

What if the Kalanchoe still dies? There are folk remedies for this pest. This is an infusion of garlic - 6 cloves per glass of water, infused for 3-4 hours and filtered.

Aphid

One of the most dangerous enemies. These are small greenish-black sucking insects that cover the leaves first from the underside. Gradually, the entire plant is covered with a pest. The leaves begin to brighten, become sticky.

This is due to the fact that the aphid secretes a poisonous substance, the respiration of the leaves is disturbed, the plant may die. Aphids are also taken into flower buds, they do not bloom and fall off.

Infection with aphids is also dangerous because it carries hundreds of viruses. And its secretions are a breeding ground for the fungus.

Leaves affected by aphids are pruned and burned; healthier parts are treated with insecticide. Laundry soap is a good aid. Surfaces are washed with its solution before poisoning.

But it will not be possible to destroy aphids in one go. The treatment is carried out 4 times at weekly intervals.

Mites

These pests settle on the lower part of the leaves. Their appearance is associated with increased dryness of the air. The flower has yellowish leaves. In addition, pests weave a thin web on the foliage, as a result of which they curl and crumble.

To cope with parasites, insecticides are used. You can also delete them manually. This can be done with napkins. Then treat the bush with mineral oil. It is also permissible to use a soap solution.

Aphids settle on the seamy side of the leaves

Lighting violation

Kalanchoe belongs to light-loving cultures, since in the natural environment of the tropics it settles on rocky slopes, in light forests, river floodplains. Therefore, the flower loves bright, but diffused lighting and long daylight hours - at least 10-12 hours.

If the leaves turn yellow or turn brown throughout the bush, you can suspect that it has been under the hot sun for too long. Symptoms of localized sunburn caused by water droplets on leaf plates are brown spots.

The way out of the situation is to find a new place for the green pet. After proper organization of lighting, Kalanchoe quickly restores its decorative effect.

The best option would be a window sill on the east or west side, where the direct rays of the sun hit only in the evening or morning. If there is a lack of natural light in winter, move the pot to the south window, if this is not possible, arrange artificial lighting.

Major succulent diseases and home therapy

Kalanchoe, like any plant, is susceptible to various diseases.

It is important to determine the disease in time and start treatment so that the flower does not die.

Late blight

The disease actively affects garden and garden plants, but indoor flowers are also not immune from a similar problem.It is characterized by the appearance of brown spots on the leaves, which gradually turn black. After some time, the disease spreads to all branches and stems, they become soft and rot.

Note! Late blight very quickly affects the entire flower. With a disease of the root system, the Kalanchoe can be easily removed from the pot

Incorrect and irregular watering, stagnation of moisture in the pot, unsuitable and too dense soil provoke the appearance of late blight. Often a similar disease is caused by irrigation with rainwater.

You can cope with the disease. To do this, remove all the affected leaves, the sections are treated with activated carbon. It is best to transplant the plant into a new pot, after irrigating it with a solution of potassium permanganate (1.5 g per 5 liters of water). Specific antifungal agents will help well.

Powdery mildew on Kalanchoe

Powdery mildew often appears on flowers next to each other in a warm, humid environment. Plaque on the leaves is noticeable on the Kalanchoe. When the temperature drops, the fungus will die, but the plant will not heal. The leaves will gradually curl and fall off, and the succulent will bloom poorly and little.

For your information! Infection often occurs from one flower to another with the help of water and wind.

Therefore, when spraying plants, care must be taken.

Many are interested in what to do if there is a white bloom on the leaves on the Kalanchoe. Treatment consists in complete control of watering, irrigation is carried out only at the root, moisture should not get on the leaf plates and stem. The pot is rearranged to another place, providing the Kalanchoe with more air and space. Be sure to carry out treatment with specific fungicides to kill the fungus.

Powdery mildew on a succulent occurs due to waterlogging

Stem rot

The reason for this disease is a sharp drop in air temperature. When the plant is damaged, blackening of the stem and leaves, softness and rotting of all parts are noted.

The main treatment is to create optimal conditions for growth and development for the Kalanchoe. The normal temperature for a flower is 15-20 ° C in winter.

It is worth remembering that at low temperatures there should not be frequent watering in order to avoid rotting of the root system.

Gray rot

A similar disease affects indoor flowers quite often. The fungus quickly spreads to all parts of the plant. On the leaves, the presence of white dust is noticeable, located in small piles. Brown water spots are present on the stem. All parts of the plant located above the site of damage die off.

Gray mold often appears with irregular and improper watering. Constant stagnation of moisture provokes the development of the disease. It is imperative to remove fallen leaves from the pot in order to prevent fungal diseases.

Treatment is carried out with special fungicidal preparations, treating the plant twice with a break of 2 weeks. Solutions are prepared according to the instructions.

Gray rot can destroy a flower in a matter of days

Ring spot

The disease is manifested by the formation of small spots on the leaf blades. At the first stage, they turn yellow, gradually turn brown. The disease develops for a very long time. At first, the specks are small in size, but gradually they merge into one large one. Leaves may turn yellow, dry out and fall off.

Important! Ring spot is triggered by a fungus. It is recommended to carefully monitor the watering of the Kalanchoe, pour water only under the root and make sure that it does not stagnate

It is recommended to treat with special preparations, the pot is rearranged to a more spacious place.

In most cases, Kalanchoe diseases are provoked by fungi, which are very fond of high humidity.

Therefore, it is important to irrigate the flower regularly, but make sure that there is no excess moisture.

6 Diseases and pests

Due to improper care, the Kalanchoe can get sick or be attacked by pests. Yellow and curling leaves should be a signal to carefully examine the flower for bugs. Most often, the plant infects aphids, especially in the summer, when the flower is exposed to fresh air or kept near an open window.

If insects are found, the plant is treated with any of the insecticidal preparations (Fitoverm, Decis, Aktara), after 2-3 weeks the treatment is repeated. Instead of an insecticide, you can use soap suds - wipe all the leaves and stems with a napkin soaked in foam, after covering the soil in the pot with a film.

Yellow or brown weeping spots on the leaves are a sure sign of a fungal infection caused by waterlogged soil. In this case, you need to remove diseased leaves, cut off the sluggish stems and treat the flower with "Fitosporin". In the future, adjust the watering and prevent moisture stagnation in the pot. If a flower is severely infected with an infection, it can only be saved by rooting cut healthy shoots.

Kalanchoe is an unpretentious plant that can be used for medicinal purposes or admire the spectacular flowering. Caring for him should be carried out taking into account all the necessary parameters. High-quality watering, timely feeding, adherence to temperature indicators, rejuvenating pruning and rooting will help to avoid problems associated with yellowing and leaf fall.

Aloe pests

Also, the plant can curl, change color and weaken due to pest damage.

Spider mite

The most dangerous is the spider mite. It is very difficult to notice it, since its dimensions are not more than 1 mm. In this case, the leaf can become covered with white spots and a barely noticeable cobweb appears. At a later stage, the stems and leaves turn scarlet.

For the treatment of adversity, drugs such as acaricides are used. As a preventive measure, the plant can be wiped with a tincture of garlic or an alcohol solution.

Shield

These insects can be easily seen. They are brown in color and look like plaques on leaves. At the same time, the leaves dry up and curl, and red-brown spots appear.

To combat such pests, you can use a tincture of garlic, which is used to rub the leaves.

Mealybug

When affected by this pest, the flower is covered with a white bloom. In this case, aloe can rot. It is not difficult to deal with such an insect. Since it does not tolerate moisture, each leaf must be washed with an alcohol or vinegar solution. For preventive purposes, dry air and soil should not be allowed. Leaves should be wiped with a damp cloth frequently. Such care will avoid the appearance of the pest.

Such insects appear in humid and hot rooms. Pests can be recognized by the silvery stripes on the leaves. Chemicals are used to combat such insects. After processing the plants, the procedure must be repeated in a week. It is better to take the affected plants to another room.

Despite its endurance and vitality, aloe needs special care. With proper care and preventive measures, you can grow a beautiful and healthy plant that will decorate your apartment for many years. Timely treatment of diseased or pest-affected leaves will help save the plant.

Why does aloe dry? This means that the plant not transplanted for a long time
... The roots have taken up all the free space in the pot, because of this, the aloe does not receive enough nutrients. He has to feed on older leaves, so the tips dry out. In this case, you need.

Before transplanting, it is better not to water the plant for several days, then it will be easier to pull it out. The new pot should be free and spacious
:

  • if the roots have grown on the sides, you need to take a wider pot;
  • if the roots grew down, the pot should be taller.

Leaves curl

Why do aloe leaves curl? So the plant shows that it not enough care
... It is necessary to wipe the leaves from dust, sprinkle with clean water once a week (in the summer, twice a week).

Thin leaves

Why does aloe have thin leaves? Possible two reasons
:

  • lack of lighting - the leaves are struggling to reach the light, while stretching and thinning;
  • lack of watering - the leaves do not have enough moisture, they become less juicy.

In general, aloe can be watered in two different ways - from the top and through the pan. The main thing to remember is that all the soil in the pot must be shed properly. If you water only the upper layer, the lower roots will lack water and nutrients. In this case, the earth will dry out quickly, you will have to water more often - the aloe can rot.

The best option is to pour water into the sump. The main roots of aloe are the lower ones, they will take for themselves the necessary amount of water. After an hour, the remaining liquid must be drained.

The tips of the leaves turn yellow

Why do leaf tips turn yellow in aloe? What to do? This usually happens with a lack of nutrition
... The centenary needs to be fed once a month with special fertilizers for cacti or. In winter, aloe rests, no additional food is required.

Also, the leaves can turn yellow if the aloe does not have enough light. In this case, it will be enough just to rearrange the plant in a more illuminated place.

Stains

Depending on the type of stains on the aloe and their color
different problems can be diagnosed:

  • brown spots indicate that the aloe does not have enough moisture (you need to change the irrigation system);
  • if the spots are soft and dark, the plant may be infected with a fungus (it is necessary to treat with an antifungal agent);
  • the leaves can become covered with black spots - this means that they are heavily contaminated (you need to wipe them from dust more often).

The leaves turned red

Thus, the agave only responds to too bright sun
, nothing to worry about.

If you rearrange it in a shady place, the leaves will soon return to their green color.

Withers

It happens that aloe dies right before our eyes
:

  • if leaves suddenly begin to fall off - the water for irrigation is too cold (it is better to always keep the water in the watering can next to the aloe, then the temperature will be optimal);
  • if the leaves take on an unhealthy look, wither and turn pale, there is too much water in the ground (watering must be urgently adjusted).

Why Kalanchoe turned yellow: 5 main reasons

This flower is considered the most problem-free among pets. It grows well in a wide temperature range, withstands drought and winter lack of lighting. Its leaves serve as a kind of indicator of health - in response to stressful conditions, they begin to turn yellow, dry out and eventually fall off.

The main reasons for the yellowing of Kalanchoe:

  1. violation of lighting;
  2. improper watering, low humidity;
  3. temperature errors;
  4. depletion of the soil, improper feeding;
  5. other problems: stress, lack of pruning, pests.

The problem of yellowing of leaves applies equally to flowering and non-flowering species; young and adult plants are not spared. To recognize and eliminate the cause, carefully examine the flower and assess the situation in the growing area.

Succulent leaves can turn yellow all over the plant at once or in some areas - it depends on various factors. Let's consider these situations in detail.
