Anthurium black spots on the leaves what to do. Anthurium leaf diseases with photos and how to treat them. We reanimate the anthurium after care errors

There are fungal, viral and non-infectious diseases of anthurium that affect the plant with improper care or infection through water, soil, insects. The vast majority of diseases are easy to prevent by following the basic rules for caring for a flower. To avoid fungal infections will allow the correct mode of watering, viral diseases are carried by pests, it is important to ensure the prevention of insecticides. It is very easy to overcome non-infectious diseases of anthurium, it is enough to provide comfortable conditions for keeping the plant.

Causes of anthurium diseases, their treatment

Leaves turn yellow

If, during the growing process, the leaves of the anthurium turn yellow what to do, many owners do not know, but the reasons for the trouble are obvious: often the problem is caused by care errors and uncomfortable conditions, to which the flower quickly reacts with protest.

Leaf damage is a sign of a diseased flower

Conditions that determine why the tips of leaves and flowers dry in anthuriums:

  • irrigation under direct sunlight;
  • dim light in the room;
  • deficiency of nitrogen bait;
  • small flowerpot;
  • watering with hard, too cold and not settled water.

Yellow or brown spots on the leaves of a plant often signal diseases that require surgical treatment. Waterlogging of the soil and low air temperature threaten bacterial and fungal diseases of anthurium leaves:

  • fusarium is introduced when changing the soil;
  • chlorosis manifests itself with a lack of iron and magnesium;
  • septoria is a consequence of drafts, cold, humidity;
  • rot is formed with high humidity, the leaves may turn brown with excessive watering.

On a note! Do not forget about the natural features of the old anthurium, when the leaves turn yellow for a natural reason. What to do? The right decision during the period of crop renewal would be to reduce watering and top dressing.

Why leaves and flowers turn black and dry

Blackened anthurium is provoked by the following factors:

  1. Irrigation with cold water. The optimum temperature of the liquid used to moisten the culture is 22-26 degrees. The permissible deviation from room temperature is 2-3 degrees.
  2. Root decay. The solution to the problem of why the leaves of anthuriums turn black should be sought in the wrong watering. Excess moisture causes blackening and death of the plant.
  3. Fungus on the roots of anthurium. With insufficient drainage, the flower begins to suffocate and dry out. To prevent the disease, you should loosen the earth and create additional holes in the pot.
  4. Hard water. Excess calcium negatively affects the level of magnesium and potassium. The percentage of capacity of iron, manganese, zinc, and boron also decreases. The deficiency of useful elements causes the anthurium to dry out.
  5. Excess fertilizer. Dosage should be halved or stop feeding temporarily.
  6. Moisture deficiency. Symptoms - the leaves began to curl and darken, a change in the usual form. It is worth paying attention to spraying the crop or putting a pan with water next to it, providing increased humidity to the plant.

blackening of anthurium leaves

On a note! Pests are the most dangerous enemy for the anthurium flower. Why leaves and flowers turn black and dry, the reason should be sought as a result of the life of whiteflies and aphids. If the fears are confirmed, the affected areas are washed with soapy water and treated with pesticides.

Anthurium not growing

If the anthurium does not grow what to do, the grower determines based on the conditions of the culture, where the main factor is the location in an open and well-lit place, without drafts. Often lovers make a mistake when planting a flower. The soil does not suit the plant, transplantation or drainage is required - additional reasons why anthurium does not grow.

Remember! The flower prefers plastic containers, a deep-fiber substrate and does not tolerate exposure to direct sunlight. Pots for young individuals are changed once a year, for adults - after 3-4 years.

Fungal diseases of anthurium, their treatment

Microscopic fungi may remain on the plant when purchased or appear with abundant watering. Anthurium is a moisture-loving culture, the probability of the spread of bacteria is as high as possible.

Peronosporosis

The leaves of "male happiness" are covered with white, yellowish spots, gray spores are observed on the reverse side. The source of the disease is a microscopic fungus that is extremely sensitive to moist air. It is easy to cure peronosporosis - it is enough to reduce the humidity of the air and treat the culture with contact fungicides ("Topaz", "Acrobat").

Rust on anthurium treatment

When light spots appear on the upper side of the leaf, and brown spots-pustules appear on the lower side, it is highly likely that the anthurium began to get sick with a fungal infection such as rust. At the bottom of the leaves, spores develop quite quickly, the spots merge together, the leaves dry up. For the treatment of the disease, fungicides are used ("Albit", "Alirin", "Fitosporin").

Rust is a common disease of anthurium

Fusarium wilt

Fusarium is transmitted in many ways, including water and air. New spores of the fungus can grow with temperature changes and chemical attack. Fungal wilt of anthurium gives out a light pink bloom on the root collar, wilting of the leaves. The main measure to combat fusarium is prevention, for example, feeding the soil with the antifungal drug "Glyocladina". Systemic pesticides "Vitaros", "Rovral", "Fundazol" are also well established in the fight against fusarium.

Septoria

Fungal mycosis appears on the leaves as red spots circled in yellow lines. The leaves begin to fade gradually, and the plant dies. The main method of treatment is the treatment of the culture with copper-containing fungicides (Bordeaux mixture, copper sulphate, Kuproksat).

Anthracnose

Fungal disease leads to thinning and drying of the leaves. Dry brown spots appear on the edges or in the middle of the leaf blades. Systemic fungicides ("Fundazol", "Acrobat", "Ridomil Gold") will help in the fight against anthracnose. The spores of the fungus are quite tenacious, if the anthurium could not be saved, you should treat the neighboring plants with pesticides, ignite the old pot and grow a new individual in a safe environment.

late blight

Symptoms of the disease are the appearance of purple-brown spots on the leaves, their rapid development on the plant and damage to the roots. To destroy late blight, systemic fungicides are used, including Fitosporin-M, Fundazol, Alirin-B, Previkur. You will definitely have to replace the soil, lower the roots into clean water, rinse and burn the pot. The root system is also treated with a weak solution of potassium permanganate.

Pests

Indoor anthurium, in addition to diseases, can dry out or rot under the influence of insects: aphids, thrips, spider mites, scale insects or whiteflies. When pests appear, a soapy solution or insecticide will be required, the culture will have to be processed every 2-3 days.

Aphid

It is easy to recognize the defeat of anthurium by aphids by yellow, twisted sheets, sticky secretions, the plant begins to die quickly. The simplest pest control measure is a warm shower or spraying the plant with soapy water (20 g of laundry soap per 6 liters of warm water). A more effective solution would be the use of drugs: Antitlin, Aktara, Aktellik.

Aphids on anthurium

thrips

spider mite

Spider mites give out small yellow specks on the outside of the leaves, merging into huge spots. A cobweb full of small insects appears at the bottom of the leaf. Ticks love heat and dry air. As soon as the flower turns yellow, it is important to urgently treat the leaves with soapy water, clean them from insects and wipe them with mineral oil. Adjust humidity and temperature.

Shchitovka

Whitish or golden-brown tubercles on anthurium leaves are the first signs of a scale insect sucking the life juices of a home flower. A regular needle will allow you to remove the pest from the sheet. Single individuals are also cleaned with a toothbrush, wiped with a cotton swab soaked in kerosene - under the kerosene film, the shield will suffocate.

whitefly

The flower looks oppressed, the leaves curl and discolor, the buds and flowers fall off. It is worth carefully examining the pet, especially the underside of the leaves. Perhaps the plant has become a haven for insect pests - whiteflies. Small moths with many larvae suck out the vital juices of anthurium. Whitefly secretions on the upper part of the leaf are similar in consistency to a sticky, shiny coating, similar to sugary stains. When a whitefly appears, experts advise resorting to the use of chemicals: Aktara, Konfidor, Akarin, Iskra, Fitoverm, Aktellik, Tanrek.

Whitefly on a healthy plant

Noncommunicable diseases

Chlorosis

If yellow spots are visible on green foliage in bright light, the culture suffers from poor nutrition (lack of magnesium and iron). It is important to take care of regular feeding of the plant with fertilizers for decorative flowers.

smallpox

Yellow-green bulges and annular yellowing are the result of low temperature combined with high humidity. If you forget about the regular feeding of anthurium, the plant will not have the strength to resist smallpox, it will take a long time to reanimate the culture.

Enation

When a flower becomes ill with enation, an uneven curvature of the leaves, an ugly and humpbacked appearance are visible, the anthurium may turn black. The disease progresses in cold rooms with drafts, sudden changes in dry, moist air.

Anthurium needs an urgent transplant

Anthurium is a beautiful and unpretentious exotic culture. When keeping a plant at home, it is worth establishing proper care for and preventing diseases. The flower will decorate the interior for more than 10 years.

Anthurium or male happiness catches the eye thanks to the magnificent inflorescences, painted in the brightest colors of the spectrum: red, purple, yellow, pink, blue. Glossy anthurium leaves are also decorative, and some varieties are distinguished by a silvery frame of veins. Anthurium is considered an unpretentious plant, but for beautiful flowering and growth, it needs certain conditions. If your plant has a diseased appearance, analyze the maintenance errors and eliminate them, guided by our tips.

Optimal growing conditions

Anthurium moved to our apartments from the tropics of Central and South America, so it got used to shading. The best place in the apartment for him will be the window sills of the western and eastern windows. The optimum growing temperature is 16-20°C in winter and 20-25°C in summer.

Anthurium is a big fan of moisture. Like many tropical plants (zamiokulkas, monstera, calla), with high soil and air humidity, anthurium is able to “cry” due to special pores on the leaves. But it is worth remembering that in everything you need to know the measure. A non-drying, wet substrate will quickly lead to rotting of the roots and death of the plant.

The soil for anthurium, as for most epiphytes, should be fairly light, slightly acidic. An excellent option is ready-made special soil mixtures for aroids.

Important! All parts of the anthurium, like most plants of the aroid family, contain poisonous juice, so it is necessary to isolate it from small children and pets.

Mistakes in anthurium care are usually easy to fix (rearrange the plant from a battery, water more or less, feed, change the window sill, etc.), but dealing with dangerous diseases and pests is not so easy.

fungal diseases

As mentioned above, anthurium is a moisture-loving plant, therefore it has a high chance of becoming infected with mycoses. These are diseases caused by microscopic fungi that love a humid environment.

Downy mildew (downy mildew)

Whitish, yellowish spots appear on the leaves of anthurium, so familiar to gardeners. Cucumbers are often affected by this disease. On the reverse side of the leaf, the formation of gray spores can usually be observed.

The disease affects the leaves of anthurium. Chlorosis spots of a rusty hue appear on the outer surface, and active sporulation occurs on the lower surface. Just as in the case of downy mildew, the main method of combating and preventing leaf rust is to maintain optimal air humidity. For prevention, biological fungicides can be used, for example, Albit, Alirin, Fitosporin.

Anthurium leaf affected by rust must be treated with a fungicide

This type of mycosis inhibits the entire plant as a whole. The fungal nature of anthurium wilting is given out by a pinkish-white coating that forms on the root collar. The causative agent of the disease is a species of fungus of the genus Fusarium (Fusarium).

Unfortunately, infection with Fusarium occurs in many ways, including through water and air. And the spores of the fungus are extremely tenacious and resistant to high temperatures and chemicals. Therefore, the main thing in the fight against fusarium is prevention, for example, the introduction of the antifungal drug Glyocladin into the soil. Systemic fungicides Vitaros, Rovral, Fundazol also worked well in the fight against fusarium.

Fusarium wilt depresses the entire plant

Septoria

This common fungal disease appears on the leaves with brown spots, sharply outlined by a yellow rim. In the future, wilting of the leaves and death of the plant occurs. The main treatment is the treatment of anthurium with copper-containing fungicidal preparations (Bordeaux mixture, copper sulphate, Kuproksat).

Brown spots with a yellow rim on anthurium leaves are a sign of septoria

Anthracnose

Another disease of anthurium, which has a fungal nature. Leaves begin to dry and thin. Dry brown spots may appear from the edges or in the middle of the leaf plate. If urgent action is not taken, the plant will dry out rather quickly and soon die.

With anthracnose, anthurium leaves begin to dry from the edges

Treatment should be carried out with systemic fungicides (Fundazol, Acrobat, Ridomil Gold). It is also necessary to treat the soil containing fungal spores with fungicidal preparations. If the anthurium could not be saved, the remaining indoor plants should be secured. The spores of the fungus are extremely tenacious, so the vacated pot must be ignited. If this is not possible, then such dishes will have to be disposed of.

late blight

Anthurium is quite rarely affected by phytophthora; nightshade plants still suffer from this disease more often. Despite this, if you notice small purple-brown spots on the leaves, you need to take urgent action. Late blight develops very quickly and affects the root system, dooming the plant to an early death.

The best option for controlling late blight is the use of systemic fungicides. Among them are Fitosporin-M, Fundazol, Alirin-B, Previkur. In this case, you will definitely have to replace the soil, thoroughly rinse the roots under water, and heat-treat the pot or replace it with a new one. The roots can also be treated with a weak solution of potassium permanganate.

Pest infestations

On sale there is a huge number of chemicals to combat aphids, they can be purchased at any specialized store. The most famous of them are Aktellik, Fitoverm, Akarin, Aktara. You can also use the traditional remedy for aphids - treat the plants with a solution of warm soapy water or tobacco infusion.

Young aphids reproduce very quickly on succulent leaves and stems of houseplants.

This microscopic arthropod cannot be seen with the naked eye. Its size is only 0.5–1 mm. Nevertheless, such a crumb can deliver a lot of trouble. The spider mite feeds on the sap of host plants. When infected with a pest, the anthurium ceases to develop normally, the affected leaves turn yellow, which subsequently leads to the death of the plant.

Unfortunately, after 3-4 days, young growth will hatch from the soil, and the processing will have to be repeated in the same way. Anthurium will need to be processed 2-3 more times at weekly intervals.

Spider mites are only visible under a microscope.

Shchitovka

These harmful sap-sucking insects are a real disaster for indoor plants. Scale insects are reliably protected from external influences by a special “shell”, so it is not easy to get rid of them. Shields are visible to the naked eye. Cause the appearance of black spots on the leaves, wilting and subsequent death of the plant.

If you notice signs of damage to anthurium by a scale insect, place the plant in a "quarantine" so that it does not infect healthy counterparts.

To get rid of scale insects, they are manually cleaned from leaves and stems with a soft cloth. After that, it is necessary to treat the plant with special chemicals (Aktellik or Phosbecid), following the instructions. Be careful - these drugs are toxic! It is best not to process indoors.

thrips

Plants suffer not only from adult thrips, but also from their larvae and nymphs Under optimal conditions, thrips can double their population in 4-6 days.

Anthurium resuscitation

Even if the anthurium has lost all the foliage, this is not a reason to get rid of it.

Living anthurium rhizomes can still be reanimated

First of all, you should find out what caused such a deplorable state - improper care, diseases or pests. Next, you need to do the following:

A disease introduced with the soil can destroy a weakened plant. Therefore, it is very important to disinfect the new soil in any way possible:

  1. Steam processing. The soil is spread on a fine mesh over boiling water for 30-40 minutes. This is a laborious but very effective way.
  2. Freezing. The soil is kept at a negative temperature for a week, then brought into a warm room for thawing. This is a long process and the easiest way to do it is in winter, when you can use the balcony as a freezer.
  3. Potassium permanganate. This is the lazy way. All you need to do is spill the soil with a raspberry potassium permanganate solution and wait 30-40 minutes until the soil dries out.

Anthurium feels great in the conditions of our apartments. But you should be very attentive to his needs and take timely measures to prevent possible diseases. If you take care of the plant correctly, then the anthurium will delight you with the brightest flowers of the most exotic colors throughout the year.

Anthurium is beautiful and exotic, only when growing it is often necessary to deal with diseases of a capricious flower. Anthurium can fall ill both from improper maintenance and care, and from various diseases, it is also attacked by pests. In the article, we will consider all the most common ailments and diseases of anthurium, find out how to treat the plant.

general information

Anthurium or, as the people say, "male happiness" is a tropical, thermophilic and tender flower. The plant is very sensitive to external conditions, watering, fertilizing and other care. Deviating from the correct agricultural technology, you can soon notice the indisposition of the flower.

If you see that the anthurium looks bad, weakens, the leaves turn yellow, suspicious spots appear on them, other alarming symptoms are observed, you should examine the flower as soon as possible.

Having identified the problem, you need to deal with its eradication. In most cases, it is enough to normalize the conditions of detention and pay more attention to care. However, sometimes the anthurium gets sick quite seriously - then more effective measures have to be applied.

In total, there are three big factors that are the causes of anthurium disease:

  • violation of agricultural technology and maintenance in unsuitable conditions;
  • infectious diseases;
  • pest infestation.

Each of these factors hides many specific reasons that cause a flower to feel unwell in individual cases.

Violation of agricultural technology and conditions of detention

These reasons are the most common when cultivating an exotic handsome man at home. Most often, it is due to improper care and maintenance that the flower starts to hurt. Fortunately, the situation in this case can be corrected quickly, the main thing is not to delay.

No flowering

The problem is most often associated with a violation of the conditions of detention. In much more rare cases - with infectious diseases. The following factors can cause the cessation of flowering:

  • too cool external temperature (below +18 degrees);
  • finding a plant under drafts;
  • exposure to direct sunlight;
  • standing water in a pot.

The last reason is the most common. Anthurium roots are very sensitive to the level of soil moisture, and allowing waterlogging of the soil is critical for the plant.

What to do

They cause flowering in this case by eradicating the cause that gave rise to the absence of buds. In any case, additional feeding with complex minerals will not hurt either.

Spots on the leaves

Often, improper care leads to the appearance of ugly spots on the leaves, slow growth, and discoloration of the foliage (see photo). Sometimes you can see brown spots not only on the leaves, but also on the neck of the plant. The first step is to assess what kind of spots appeared:

What to do

The nature of the spots should be assessed and the cause that gave rise to their appearance should be eliminated. But if the plant turned out to be flooded, it is recommended to transplant it into another pot with dry soil. Cut off rotten roots before transplanting.

The flower dries up

This usually happens due to insufficient soil moisture, less often due to too low air temperature.

What to do

As in other similar cases, it is necessary to correct the situation by normalizing the conditions for keeping and caring for the plant. That is, water and place the flower in a warmer room. Feeding won't hurt either.

Enation

This disease is expressed in the drying of the flower, the deformation of the leaves, the appearance of ugly growths on them (see photo). The disease has a non-infectious nature and why it appears is not yet known exactly. However, it has been noticed that more often enations are observed after the anthurium has been exposed to sudden changes in temperature.

What to do

You can cure a flower in this way: you should normalize the conditions for its maintenance and prevent strong temperature fluctuations. Gradually, the plant will return to normal, and ugly defects in its appearance will disappear on their own. Do not forget to feed the plant so that its immunity is always high.

smallpox

Although this is a disease, as in the previous case, however, it is non-infectious, non-contagious and occurs due to non-compliance with the rules of care, poor maintenance. A symptom is ugly growths on the leaves of a convex shape (see photo).

What to do

The pot must be removed to a warmer place, protected from direct sun and drafts. Usually this is enough.

Other ailments

It happens that the anthurium grows very weakly, develops poorly. The reason is usually a lack of nutrients. In this case, you need to either apply fertilizer, or (if the soil is very depleted) transplant the plant into a fresh substrate.

The leaves turn yellow and dry, and the root neck turns brown and mold appears on it due to critical waterlogging of the flower. In this case, you can not hesitate - urgent resuscitation measures are needed. It is necessary to transplant the anthurium and remove all damaged, rotten fragments.

Attention: after removing the affected parts, do not forget to sprinkle the cut points with crushed coal or ash for disinfection and faster healing.

Infectious diseases of anthurium

Anthurium, due to its delicate constitution, suffers from infectious diseases quite often. But still less often than from violations of agricultural technology. You should not despair if some disease has struck the flower - thanks to the high level of modern fungicides and timely treatment, almost any situation can be corrected. Next, let's go through the most common diseases.

Anthracosis and septoria

These are fungal diseases, most often affecting anthurium. A symptom of both diseases are brown and reddish spots that appear on the leaves (see photo). The tips of the leaves may also turn black.

What to do

Watering for fungal diseases should be reduced, since it is often waterlogging that causes them. Treat with chemical fungicides. The composition of fungicides must necessarily include copper - it is this mineral that helps to quickly deal with the pathogen fungus. The earth also needs bactericidal treatment: Abiga-Peak is suitable for this purpose.

Affected parts should be removed and burned before processing. If the processing of the results did not give, you will have to part with the flower: it is destroyed along with the earth. The pot may still come in handy, but it must be thoroughly washed, treated with a disinfectant solution and thermally.

Gray rot

The disease also has a fungal nature and first affects the stem of the plant, then the shoots, and lastly the leaves (see photo). The infection spreads very quickly, and in the shortest possible time the affected areas of the flower die off.

What to do

It is necessary to get rid of rot immediately, as soon as the first signs are noticed. Highly effective chemicals should be used - only they can be guaranteed to save the plant. Folk remedies in this case will not help.

All affected fragments should be removed, and then chemical treatment should be carried out. There should be at least three such treatments - after short breaks. If the case is already running and the treatment does not help, the flower is destroyed.

Fusarium

This fungal disease leads to wilting and shedding of anthurium foliage. The disease affects the roots of the plant, therefore it is extremely dangerous and often leads to the death of the flower. The first sign is a sudden and sharp wilting, wilting of the anthurium. Peduncles bend at an unnatural angle, the foliage turns yellow suddenly and strongly (see photo). With this disease, the fungus penetrates the tissues of the plant, clogging the vital vessels.

What to do

A diseased flower should be urgently isolated from other indoor plants. If the disease did not have time to strongly affect the plant, you can try to cope with it with additional mineral supplements that increase the immunity of anthurium.

And if the disease did not have time to hit the root, you can try to cope with Fusarium with a copper fungicide. Experienced flower growers use the following method:

  • get the plant out of the ground, wash it off the ground;
  • withstand the roots in a solution of Fundazol (weak);
  • cut off the affected and rotten parts of the plant;
  • transplant the anthurium into a new soil and a new pot.

If the treatment does not work, the flower is destroyed.

If the roots are already affected, you can cut off the top of the flower and try to root it. Before placing in the ground, hold the lower part of the top in a solution of Fundazol for half an hour.

The best way to deal with this dangerous disease is prevention and prevention in principle of its occurrence. When planting a flower, in order to prevent fusarium, it is recommended to add several granules of the Trichodermin preparation to the soil. In addition, it is necessary to constantly take care of maintaining the health and high immunity of the plant.

Rust

This disease cannot be confused with another, since a symptom of rust is very characteristic brown-rusty spots on the leaves. The spots spoil the decorative effect of the flower and gradually spread, becoming wider, the foliage then dries up and falls off. Look at the photo of anthurium leaves affected by rust.

What to do

Rust should be treated by treating the flower with chemical and alcohol fungicides. Processing is carried out every 3-4 days for two weeks. As drugs suitable:

  • Ordan;
  • Topaz.

Fitosporin-M can be used as a prophylactic against rust.

With this disease, it is impossible to spray the plant, since the spores of the fungus can quickly move on to healthy leaves. The treatment is carried out by wiping the leaves with a fungicidal solution.

root rot

The disease usually occurs due to systematic waterlogging of the flower. The disease is dangerous, as it can lead to the death of the plant.

What to do

The anthurium is removed from the pot, the roots are inspected and the rotted ones are cut off. The remaining healthy rhizomes are treated with Maxim or Fitosporin-M preparations, after which they are transplanted into a new pot with dry soil. Do not forget to read the description of the drugs in order to choose the right dose, proportions. For some time after transplanting, watering the plant is not worth it.

powdery mildew

The disease usually occurs due to keeping the plant at a low temperature simultaneously with waterlogging.

What to do

If the flower is flooded, a transplant is required. In other cases, you can do with moving the pot to a warm place and spraying with Acrobat, Topaz.

Pest infestation

Aphid

Since pests multiply very quickly, you need to get rid of them quickly. Fortunately, it is not difficult to get rid of aphids: you just need to buy the right insecticide and treat the plant. A day after treatment, the leaves should be washed with water to wash off dead and still living insects from them. Yes, and from a chemical burn, such washing of the leaves will protect.

Shchitovka

What to do

When the scutellum multiplies, insects can be seen with the naked eye: treatment should then be taken urgently. The flower must be isolated from other plants and washed with water.

Then an insecticidal treatment is performed, a day after which the flower should be washed again. There should be two treatments in total. If the scale insect has not yet had time to multiply, you can try to cope with it with the help of an ordinary soap solution.

Mealybug

This pest is the easiest to deal with, since you can notice it almost immediately. The worm covers the leaves with a whitish bloom, which immediately catches the eye. However, if rescue measures are not taken quickly, the worm can even kill the anthurium.

What to do

You can cope with the misfortune by washing the flower with a soapy or alcohol solution. After processing, be sure to rinse with clean water. For a guaranteed result, the treatment is carried out in two stages: the second one a week after the first.

Whatever malaise happens to the anthurium, useful general tips on care and maintenance will come in handy in any case.

Air humidity level

When growing a tropical flower, it should be remembered that high humidity is a vital necessity for it. The humidity level should be 70-80%, if less - then only for a short time.

In order to ensure such humidity in the conditions of our apartments, you will either have to spray the plant more often, or purchase a special humidifier, or put the flower on a pallet with wet expanded clay. The last option is the least labor-intensive, and it will not require any expenses.

Why spraying is not the best solution? Because water leaves whitish ugly spots on the leaves.

If the flower grows in a dry room, it will get sick more often and is more likely to be affected by a spider mite. In addition, dry air leads to:

  • drying and yellowing of foliage;
  • in severe stages - to twisting and blackening of the leaves;
  • drying of buds - both blooming and not yet.

Air temperature

Since this plant is thermophilic, it must be kept at a temperature not lower than +18 degrees in summer and +16 degrees in winter. The best option and most suitable for a flower will be its content from May to September at a temperature of + 25-28 degrees.

Drafts, cool breezes of the wind are completely contraindicated for the plant. Under the influence of drafts, the roots of anthurium often rot, its flowers and leaves freeze. And spraying in winter, followed by opening the window for ventilation, is the most reliable way to destroy a flower.

Lighting

Anthurium needs abundant lighting, which is important for its lush and long flowering. However, the plant does not tolerate being in direct sunlight (especially at noon). In nature, it grows on the lower tiers of tropical forests, shaded from above by tall trees.

Place the flower in a place that is well lit but shaded. In winter, the anthurium will require additional illumination for normal functioning.

Watering and substrate features

It is best to grow a flower in moist and permeable, loose soil. Watering should be done only with soft water without impurities of salts and bleach. If the air humidity is maintained high, it is often not worth watering.

So, we learned what diseases and why anthurium suffers and found out how to cure the plant in each case. The main disease control measure is the proper care of the plant and its maintenance in suitable conditions. By fulfilling the requirements of agricultural technology, you will reduce the likelihood of a flower disease many times over. Well, if, nevertheless, the plant picks up an infection or pests, you should not hesitate with treatment: the sooner you start taking measures, the greater the chances of success.

When the anthurium is healthy, its foliage has a smooth surface, the color characteristic of the variety without traces of yellowness or dried spots. The leaves are quickly renewed, and reappearing without difficulty and damage unfold. This can be achieved by creating the conditions necessary for the growth of anthurium and providing it with competent regular care.

Possible causes of drying and spots on anthurium leaves

Flower growers who know the characteristics of a flower consider anthurium to be a very unpretentious and grateful indoor plant. And yet, lovers of this culture sometimes have to face some problems, most often related to:

  • with errors in the organization of irrigation;
  • in violation of the feeding schedule;
  • with excessive dryness of the air;
  • with improper plant lighting.

A little less often, anthurium leaves and he himself suffer from sudden changes in temperature and keeping the flower in a cold room.

As a result of a prolonged violation of the conditions of maintenance and care, plants are at risk of being affected by rot and fungal diseases that threaten, if urgent measures are not taken, the death of the pot culture.

Anthuriums can be attacked by harmful insects that harm both the root system of the culture and its aerial parts.

So why do anthurium leaves turn yellow? And why do brown spots appear on the leaves?

aging anthurium leaves

As with other plants, anthurium leaves may turn yellow for a completely natural reason, due to old age. In such cases, the inevitable processes, first of all, affect the foliage located closer to the ground.

Yellowness, spreading from the edges of the leaf plate, gradually covers it completely, the leaf loses its elasticity and juiciness, and then turns brown. If it is not removed, such an anthurium sheet dries and falls off on its own. If the plant is kept in proper conditions, then the fall of old leaves does not cause damage to the anthurium, because at the same time new healthy foliage actively appears at the top of the stem.

Since the process is natural and inevitable, you should not worry about it. However, flower growers often have a question: “Do I need to remove yellowed or dry anthurium leaves?”

Obviously, such leaf plates no longer fulfill their main function, but the plant spends certain forces on their maintenance. Therefore, it is better to cut off the leaves that have become obsolete, making life easier for the whole plant and making it more attractive.

To prevent the cut from becoming a site for the spread of infection, it is useful to treat the cutting tool, be it scissors or a knife, with alcohol, and sprinkle the damaged tissue on the anthurium with crushed charcoal.

If the leaf is still juicy, do not tear it off by hand, because this can seriously injure the stem.

In addition to the natural reasons why anthurium leaves become stained or dry, flower growers have to deal with the consequences of the mistakes they made when caring for a houseplant.

Spots on anthurium leaves due to excess or lack of light

The condition of the plant is strongly influenced by its location. Although in the tropics, where anthuriums are used to living in nature, there is no shortage of sunlight, it is more comfortable for plants to be in partial shade.

The appearance of spots on the leaves of anthurium, the grower may be due to direct sunlight that burns the leaf plates. It is impossible to avoid deterioration in the appearance of a green pet if the anthurium is in a rather dark place and suffers from insufficient lighting.

If the plant has stopped growing, blooms little and reluctantly, it probably does not have enough light. Anthuriums with dense dark green leaf blades suffer especially from this. Under conditions of short daylight hours or, being constantly in the shade, the cuttings of the anthurium leaves lengthen, the leaf plates become smaller and noticeably turn pale. By rearranging the plant on a well-lit window sill, you can see how it regains its former beauty, the development of yellowness and spots on the leaves of the anthurium stops.

The main thing, in an effort to provide the plant with the required lighting, is not to overdo it and prevent sunburn.

When the pot is under the direct rays of the sun, flower growers are interested in what to do, because the leaves of the anthurium turn yellow or acquire a bronze “tan”.

A good effect is given by glass tinting with a special film that reflects part of the solar radiation. If it is not possible to equip the window in this way, the plant can be moved from the glass, or during the hours of the greatest activity of the sun, any impromptu screen should be placed near the anthurium.

If urgent measures are not taken, an excess of sun appears not only on the color of the foliage, but also on its health. This includes brown spots appearing on the tips of the anthurium leaves, and the loss of affected foliage.

Excessive dryness of the air - the cause of dry anthurium leaves

Similar symptoms can be seen in anthurium, which is in a room with dry air. Most often, this reason makes itself felt at the beginning of the heating period, when the usual conditions for the plant change, and aerial roots and foliage can no longer get the required amount of moisture from the air.

Why do anthurium leaves turn yellow in this case? They just don't get enough food. Yellowness spreads from the edges of the leaf plates to the center, then the tissue at the tips and edges of the anthurium leaves dries. Young leaves developing in dry air often fail to unfold properly and are deformed or damaged.

You can’t do without additional air humidification, and you can achieve the required humidity of about 70–85% by anthurium using a household humidifier, as well as improvised means. The plant responds well if the pallet is covered with fine expanded clay and filled with water. The pot is placed on the filler so that the roots do not have contact with moisture.

Do not forget that a change in temperature and light conditions necessarily leads to the fact that the soil dries out faster or slower, and the mode of moisture consumption also changes in the plant.

This means that the schedule will have to change. It is the improper moistening of the soil under the houseplant that most often provokes the formation of brown spots, dry patches and yellowness on the leaves of the anthurium.

Anthurium leaves dry in spots - the reason is watering

The leaves are the first to react to the violation of watering and the problems caused by this. If a at anthurium on the leaves brown spots, this may be caused by moisture on the leaf blades. In the sun, such drops act as lenses and literally burn through living tissue.

It is even worse if the plant has been exposed to a humid environment for a long time. In this case, tissue necrosis does not develop in spots on anthurium leaves, but, starting from the edges, spreads to the entire platinum sheet. The soil in the pot of such an anthurium should be tried to dry, and with its increased density, which provokes the accumulation of moisture, change the entire soil.

During transplantation, be sure to examine the root system of the plant and remove all roots that are susceptible to decay.

For a plant that lives in a cool room, a violation of the irrigation regime also threatens fungal diseases.

Dry spots on anthurium leaves - the result of the activity of fungi

Like root rot, the spread of harmful fungi will certainly cause anthurium leaves to dry in spots. At the initial stage of the disease, small yellow spots of a rounded or irregular shape can be seen on the leaf plates, which gradually expand, become brown in the center and begin to dry. The tissue at the site of the stain undergoes necrosis and may crumble, and concentric dark circles become visible around.

Brown spots on the leaves of anthurium are not the only symptom of the disease. Fungi and putrefactive microorganisms cause the main damage to the root system.

Therefore, when similar spots appear, the anthurium must be carefully removed from the pot and the roots examined. If the roots of the plant have changed from a white or light cream color to a brown or black tint, their tissues have become soft and slimy - this is a clear sign of root rot. This plant needs:

  • remove the remains of the substrate;
  • cut disease-damaged and dry anthurium leaves;
  • cut off all damaged roots to a healthy white tissue;
  • process slices with crushed coal;
  • and the whole plant fungicide.

After that, the anthurium is transplanted into a new soil, previously, like a pot that has been disinfected.

The new substrate should be loose so that any excess water leaves the soil easily and does not harm the roots. After moistening the soil, the drained liquid must be removed from the pan, and until the next watering, they wait until the surface of the earth under the plant dries out.

It is important to remember that only settled warm water at room temperature is taken for watering anthuriums.

Deficiency and excess nutrition of anthurium

If the plant has stunted growth, and its young leaves are smaller than the ones that opened earlier, the anthurium is probably suffering from a nutritional deficiency. The lack of basic elements, for example, phosphorus or potassium, leads to the fact that the leaves of anthurium turn brown. A similar effect can be expected if the substrate lacks calcium or magnesium.

For feeding anthuriums, liquid ready-made products are used, which are used weekly to restore a damaged plant, using a 25 percent concentration of that recommended by the manufacturer. When the pet gains strength, you need to fertilize it every two weeks.

Sometimes not only a lack, but also an excess of fertilizer causes the development of yellow and brown spots on anthurium leaves. In case of an overdose of top dressing, it is better to transplant the plant into a new soil, after washing the root system.

Pests on anthurium leaves

Shchitovka, all kinds of mites, aphids and mealybugs are the insects that most often cause damage to indoor anthuriums .

And asking why the leaves of anthurium turn yellow, flower growers should carefully examine the stem of the plant, paying attention to the area near the ground, leaf petioles, their leaf blades and sinuses.

At the first sign of insects, the anthurium is treated with ready-made complex insecticides or a soap solution, to which 1 gram of nicotine sulfate is added per liter of water. Since insect control agents are toxic, a day after treatment, the plant is washed with clean water, protecting the soil from excessive moisture.
