How to deal with spots on anthurium leaves. Anthurium: diseases and their treatment Appearance of diseased anthurium sheets

Anthurium is a guest of a distant country with a different climate and requirements for living conditions. Pampered by a long warm period with fairly bright lighting, a light composition of the substrate, and sufficient air humidity, under new conditions, exotics often become the object of disease and pest damage. Outwardly, the disease most often manifests itself on the leaves. Therefore, it is very important to correctly determine what got anthurium sick, how to treat leaf diseases. The descriptions, photos and drawings below will help you determine the cause and find the right solution when treating your pet.

What are the diseases of Anthurium and the causes of their occurrence

Violation of sanitary standards

The root cause of the occurrence of diseases is the attitude of the owner to the acquired houseplant. A flower needs time to adapt to new conditions. The plant needs individual monitoring to exclude the presence of infection.

To keep your flowers healthy, it is necessary to isolate all newly purchased indoor plants for 2 weeks from other crops, keep them in quarantine conditions. During this period, healthy plants adapt, continue their growth and development. Patients will show external signs of the disease.

Disease groups

Diseases of indoor plants are divided into 2 groups: non-infectious and infectious.

Noncommunicable diseases are the result of a violation of the content of the flower in conditions that do not meet its requirements. Such diseases do not affect other plants. When the source of the disease is eliminated, they recover without causing damage to other crops.

infectious diseasesand I cause pathogenic infections that necessarily affect other plants. Changing hosts, pathogenic fungi, bacteria and viruses multiply rapidly and in a short time can destroy almost all nearby plants.

Elimination of non-communicable diseases

Non-communicable diseases include: violation of environmental requirements - draft, low temperature, dry air, improperly selected substrate, top dressing, watering, natural aging of the plant.

Problem: Leaves curl all over the plant.

The appearance of the leaves speaks of problems

Cause and solution of the problem:

Improper care of anthurium;

Violated requirements for environment. The plant is located in a draft. Not enough lighting or too bright scorching lighting. Maybe the air is dry, and watering is plentiful. When the requirements are normalized, the flower recovers.

Problem: Anthurium leaves began to turn yellow.

Leaves turn yellow

Cause and remedy

• If the lower leaves gradually turn yellow.

The natural aging of the plant is manifested. It is enough to carefully cut off the old leaves with a disinfected tool. The plant needs rejuvenation. Yellowing leaves can cause disease.

The second cause of yellowing of the leaves are diseases: chlorosis, gray rot

• At young plant leaves turn yellow all over the plant.

Possibly too bright lighting. It is enough to shade the plant or rearrange it in a less lit place.

yellowing leaves on anthurium

• The green color turns pale, the leaves become yellowish.

Lack of lighting. In the autumn-winter period, additional illumination is necessary.

The leaves of the plant turn pale from lack of light.

Problem: Anthurium leaves dry out

Drying anthurium leaves

Cause and remedy

• Violation of temperature and humidity conditions.

– Possible cause is a draft. Move the plant to another place or eliminate the cause of the draft.

– There may be dry air in the room. It is necessary to install humidifiers, systematically humidify the air without getting drops of moisture on the flowers.

– Insufficient watering. If the soil is dry to the depth of the phalanx of a finger, watering is necessary. In the future, normalize the watering of the plant.

Problem: spots of different colors and diameters appeared on the leaves of the anthurium.

brown, yellow spots. From an excess of light, anthurium leaves get burned.

Cause and remedy

• Evidence of sunburn. Relocation or shading required. It appears as brown spots randomly located on leaf blades. Move to another place and create the optimal temperature regime.

Problem: young leaves are too large with an unusual pale green color. Leaves take on different colors.

Cause and remedy

• An overabundance of fertilizers, especially nitrogen.
• Violation of quantity and ratios nutrients in soil.

Additional watering is needed to flush out excess fertilizer. Adding agrovermiculite to the substrate. Reduce doses or temporarily eliminate top dressing. If the rules for feeding are not violated, a lack of trace elements is likely. Carry out top dressing with a half dose of microelements (buy in a store).

Problem: the tips of the leaves dry out throughout the plant, sometimes the leaf turns completely black.

Cause and remedy

• Perhaps the humidity of the air and soil is greatly reduced;
• roots lack pot space;
• little oxygen is supplied to the roots;
• the soil is overly fertilized, contains an increased amount of calcium.

If the humidity is normalized, but the tips continue to dry, sometimes gradually capturing the entire leaf blade, it is necessary to transplant the anthurium into a new, properly prepared substrate, reduce the doses and reduce the number of top dressings.

Problem: the inflorescence dries and blackens.

Cause and remedy

• The natural flowering period ends;
• Too bright lighting, possible sunburn;
• The flowers got water when spraying;
• The humidity regime of air and soil is disturbed.

Cut off diseased inflorescences with a bract. Shade the plant. Normalize the humidity regime. In the pallet, expanded clay or pebbles should be kept constantly wet. Exclude when spraying and watering the ingress of water on the inflorescence and the bedspread.

Problem: Anthurium leaves lose turgor, wither, but do not fall off.

Cause and remedy

• Too frequent and abundant watering;
• Damage to the root system by fungal rot.

The plant must be urgently transplanted into another disinfected pot or other flower container. Change the soil completely. Rinse the roots in warm water with a weak solution of potassium permanganate. Cut off diseased roots. Dry for 20-30 minutes. Treat with root and land, observing all the rules.

Infectious diseases of anthurium

If all the violations made when caring for the anthurium were corrected, but the flower continues to hurt, and nearby plants began to fall ill, this is clearly an infectious lesion.

Of the infectious diseases, Arturium is most often affected, with most diseases transmitted through the external environment:

• stem and root rot;
• leaf rust;
• anthracnose (powdery mildew present and false);
• fusarium wilt;
• septoria, etc.

When treating houseplants, it is safest to use biofungicides. They do not harm the health of humans, animals and birds. They can be used in tank mixes with bioinsecticides (against pests). Treat plants with a disease at least 2 times a month. For prevention, treatments are carried out once a month, less often if the plants look absolutely healthy.

Stem and root rot

The plant as a whole quickly fades. Depressed dark spots appear on the surface of the roots and near the basal part of the stem, covered with a white or gray dense coating. This plaque is the mycelium of the fungus, which forms asci with spores (small black dots are visible) that infect other plants. The stem is watery, rotten when touched.

Dense gray mold appears on leaves and even (in advanced cases) on inflorescences. Typical for young plants recently transplanted into new containers with fresh substrate.

Causes and treatment

The mycelium of the fungus, growing in the soil, is introduced into the root system. Infection occurs during transplantation into infected, poorly disinfected soil, poorly prepared planting capacity. The cause of the disease may be abundant watering with poor drainage, lack of ventilation.

For treatment, remove the plant from the pot. Replace thoroughly decontaminated substrate and planting container. Examine the plant, cut off all the affected roots and leaves. Wash the roots in potassium permanganate, treat according to the recommendations with biofungicides:

• root;
• planriz;
• phytodoctor;
• phytocide;
• gaupsin.

You can spray the above-ground mass with the same preparations or use biofungicides in tank mixtures:

• trichodermin;
• phytosporin-M;
• hamair;
• Alirin and others.

leaf rust

The causative agent is a group of rust fungi that have the ability to long time maintain viability on infected plant debris.

rust on anthurium

External manifestation of the disease

Loose thickenings are visible on leaf blades and stems orange color. The brown-rusty shade determined the name of the disease. With a strong infection, the leaves and the whole plant dry out and fall into the shortest time.

Causes and treatment

Transfer of spores from other infected plants. The content of plants in conditions of violation of the temperature and humidity regime. Too frequent and abundant spraying. Lack of ventilation. The plant can bend to one side due to damage to the stem.

• To prevent fungal diseases, anthurium leaves are wiped with a 1% solution of Bordeaux mixture on both sides.
• Sick leaves and shoots are torn off and burned.
• For treatment, the same biological products are used as for protection against rot. The diseased plant is sprayed 2 times a month.

You can use chemical fungicides Topaz, Ordan, Acrobat. Be careful. The drugs are poisonous. Spraying should be done in separate room in compliance with the measures of personal sanitary protection.

Powdery mildew in anthurium

The causative agents of anthracnose or powdery mildew (false and real) are a group of peronospore fungi. The spores of the fungus have increased ability be preserved on plant residues in harsh environmental conditions.

External manifestation of the disease

With a local lesion, a white-grayish pubescence appears on the lower, and then on the upper sides of the leaf, like a slight coating. With severe damage, the plant acquires a chlorotic appearance. violated external structure plants (leaves shrink, internodes shorten).

Causes and treatment

The main reason is high humidity and temperature regime(higher or lower than optimal). When keeping the plant in conditions of low temperatures, refuse spraying. Air humidity and high temperatures can be reduced by ventilation without cooling drafts.

For treatment, wiping the leaf blades with a 1% solution of Bordeaux mixture or a solution of systemic contact chemical fungicides - Acrobat, Topaz, etc. is used.

It is safer to use biofungicides for spraying and incorporation into the soil during irrigation:

• gaupsin;
• trichodermin;
• planriza;
• gamaira;
• pentophage;
• bactophyta;
• pseudobacterin.

The use of biofungicides will provide maximum effect when applied as recommended.

Fusarium and Septoria

Fusarium and Septoria wilts infect plants upon contact with infected soil and with air currents saturated with spores. Fungal spores are highly resistant to high temperatures and some chemicals which makes disease prevention difficult.

Anthurium - diseases (septoria, chlorosis)

Fusarium damage to a flower Male happiness

Causes and treatment

Failure to comply with the phyto-sanitary regime when buying new plants. Violation of the requirements for plant transplantation. Do not allow the soil coma to dry out with abundant watering.

• Of the chemicals used to treat plants and soil, Vitaros, Fundazol, Acrobat, etc.
• Of the biofungicides, the same tank mixtures are used as for other fungicidal lesions of anthurium.

Dear readers! You got acquainted with the external manifestations of the main non-infectious and infectious diseases of anthurium. Non-communicable diseases, with the normalization of basic environmental requirements and proper care, are curable. Infectious diseases, spreading many times faster, affect nearby growing plants. These are mainly fungal infections, each of which has its own characteristics. With proper diagnosis and protective measures, plants can be saved. But if the defeat is extensive, better plant destroy.

Indoor flowers, which are used by people from distant countries, are beautiful, but they are slaves who were placed in a cramped pot and a different climate. Can a plant thrive in conditions alien to it? Only imitation of the native climate allows you to get a healthy beautiful flower. At the slightest deviation from normal conditions of detention, anthurium diseases occur. At the first changes in the type of bush, it is necessary to analyze the conditions of detention.

Anthurium diseases at home

A healthy flower captivates with its beauty. Suddenly, the state of the plant can change. Any disease occurs for reasons:

• non-compliance with the requirements of agricultural technology;
• infectious diseases;
• insect pests introduced from outside.

There are people who fundamentally do not keep animals and flowers in their living quarters. They believe that the zoo, and room content is a violation of wildlife. A bouquet of fresh flowers is unacceptable for them, one cannot rejoice at a ruined life, even plants.

Non-infectious plant diseases are associated with the appearance of spots on the leaves, a change in their color, or growth retardation. Sometimes brown spots or mold on the neck of the plant become noticeable. What to do if there are spots on the anthurium? Much can be learned from the nature of the deformation:

1. If dark dots appear on the leaves of the anthurium, gradually expanding, it is cold. The same spots can appear from sunburn with direct contact of the summer sun with the leaves.
2. The reason for the appearance of spots can be watering with unsettled water or water of increased hardness. If scale forms on the kettle over time, then this is a sign of hardness. Before watering, such water must be defended for a long time or passed through a filter - softener. Another way, mainly for rural areas with hard water from wells, is the incomplete freezing of water in a container. In this case, the ice will have a lower salt content than the remaining water.
3. Others physiological reasons the appearance of dark spots and drying of the plate from the edge, there may be drafts and low temperature content in winter. Abundant watering is also accompanied by a signal of dark dots on the leaves. What to do if spots appear on the anthurium? Remove the provoking causes and patiently wait for the results.
4. Yellow or pale leaves of plants or spots of this color indicate that the anthurium does not have enough lighting. In addition, this may be a signal that the roots are sick and do not provide nutrition to the plant.
5. The general pallor of the leaves signals a lack of nutrition. The same is indicated by the absence or weak growth of the plant, the absence of flowering. If the plant was transplanted recently, then it needs to be fed. Sometimes it is better to replant the plant. At the same time, prepare the desired composition of the substrate or buy ready soil. Disinfection of the soil and the planting pot is necessary.
6. If the irrigation regime is violated and the roots of the anthurium are rotten, then this will affect the yellowing and drying of the leaves, the brown neck of the anthurium, mold may appear. The plant needs urgent resuscitation. In this case, all the affected parts must be removed and the wounds sprinkled with an antiseptic, crushed charcoal, or cinnamon powder.

Anthurium leaf diseases in the photo show characteristic damage, but often the help of specialists is required to accurately determine the disease. Drafts are detrimental to plants. This is especially dangerous in winter. Insufficient humidity of the ambient air is the answer to the question of why the leaves of anthurium dry. On the other hand, leaves may die naturally due to aging. If the leaves are curled up, remove the anthurium deep into the room, the light is too bright, he closed his eyes.

TO infectious diseases Anthurium can be attributed to the problems caused by the introduction of spores and microbes into the flower body. The difference between these diseases is that they can destroy the entire home green world if they are not dealt with. Spores are transmitted and multiply in cramped conditions quickly.

The initial causes of diseases depend on the gardener. The brought shoot, taken from a diseased plant, may already harbor viruses, from which there are no effective remedies yet. They strike vascular system. And the infection can be transmitted through a dirty tool or insects. The acquired plant must be quarantined for two weeks, in isolation from other plants. And only then move into the overall composition.

Purchased or self-composed earthen mixture should be subjected to heat treatment, pouring hot strong potassium permanganate, you need to add crushed charcoal, from rot, a long-acting drug "". It will protect the roots from late blight, fusarium and similar diseases. Competent care for anthurium - a barrier to diseases .

Diseases that are transmitted to anthurium from the external environment can be:

• septoria;
• anthracosis;
• rust.

The causative agent of septoria, the fungus Septoria, spreads in a humid and warm atmosphere. Characteristic brown spots with a yellow rim on the leaves signal an anthurium disease. The leaf dries up, when watering the spores move to other parts of the plant. The plant will die if it is not treated in time with copper-containing fungicides.

Anthracosis is a very common disease called powdery mildew. The disease is caused by the fungus Colletorichus. The spread of this disease will lead to the rapid drying of the leaves, stems and root system. Anthracosis begins on leaf blades, the appearance of brown spots with black dots in the center. These are disputes. They scatter and germinate when wet, and for the atrium this event is vital.

Atrium care for septoria disease is to reduce watering and spraying with the addition of copper fungicides. The earth is treated with Abiga-Peak. If the plant cannot be cured, it should be destroyed by burning. The ceramic pot needs to be well calcined. Dishes that cannot be burned, destroyed.

If the plant is infected with rust, then orange loose pads on the leaves will be visible. Such a plant must be wiped with a fungicide solution, but not sprayed so as not to infect healthy leaves. Sick, infected leaves are best burned.

Fusarium wilt is a formidable anthurium disease at home. It affects all plants, affecting the root system and leaves. Signs are the sudden withering of the entire bush. The first signs may be unnatural bending of peduncles, strong and rapid yellowing of the foliage. Copper preparations, soil treatment with glyocladin are suitable for the fight. the best way will wash the plant from all particles of the earth, soak a little in a weak solution of foundationol, cut off the affected parts and plant in a new dish. The old earth and plant remains must be destroyed.

Insect pests of anthurium

Insects common on house flowers include:

• thrips;
• scab;
• spider mite;
• root nematodes.

All of them suck the juice from the plant, depriving it of nutrition. At the same time, signs of the presence of pests can be found, with hygiene procedures which are carried out regularly with good care.

We grow healthy anthuriums - video

Anthurium is a beautiful plant that is grown at home. Its homeland is the tropics. Therefore, when growing this epiphyte, conditions should be created in which it can fully grow and develop. Therefore, it is very important to know if anthurium leaf diseases (photo) are cultivated, how to treat and prevent the most frequent problems with a plant.

What troubles can be encountered during cultivation. Among the main problems that can be encountered during the cultivation of a flower, the most common are diseases of the deciduous mass, namely:

1. Brown spots on anthurium leaves;
2. Anthurium leaves turn yellow;
3. Leaves fall;
4. Flowers do not appear;
5. The deciduous mass dries, dies, yellowing of individual fragments occurs.

In order for the growth and development of the plant to be complete, it is recommended to know what you may encounter during cultivation, as well as what to do in this case, how the flower is resuscitated if any disease appears.

Absence of inflorescences

Often, floriculture lovers complain that the majestic anthurium is fully developed, but at the same time, flowers do not appear on it. There can be many reasons why anthurium does not bloom, it is important to understand what caused such a phenomenon and eliminate the cause. The reason that the flowers turn green, inflorescences do not appear, often becomes a lack of lighting. When growing this plant, the intensity of lighting should be controlled, since this flower reacts equally negatively to both an excess of sunlight and its lack.

What to do so that flowers can appear? At the time when the yellow anthurium begins to prepare for the formation of flowers, it is necessary to provide for it the maximum amount of lighting. If there is a lack of natural light, an additional artificial light source is installed. So the plant will bloom and develop.

Indoor anthurium does not bloom and due to unsuitable temperature conditions. During the period when the plant is preparing for flowering, it can be transferred to a heating source. The optimal indicators for temperature are 22 degrees above zero. When too high temperature flowers may also not form, so the room temperature is reduced.

Another reason why anthurium does not have inflorescences is the non-compliance with the soil irrigation regime. Any deviations in watering can provoke the absence of flower buds. Also important is such an indicator as air humidity, as well as old dry flowers, which prevent the formation of new inflorescences, so it is recommended to cut off old flowers immediately after they have finished flowering. If the care is correct, the plant will soon please with abundant flowering.

Why do the leaves begin to dry

Sometimes there is such a problem that the leaf withered, begins to fade. Can dry a lot of leaves if not observed proper care. The key factors by which anthurium leaves dry are:

1. Insufficient air humidity;
2. Improper irrigation of the soil substrate;
3. Septoria can also cause anthurium leaves to dry;
4. The negative impact of various pests.

Having found out why the leaves of the flower dry, it is necessary to begin treatment. Timely detection of the problem and the reason why it appeared allows you to restore the green mass of the plant.

To eliminate such a problem as high humidity, it is recommended to place near flower pot container with water, more often spray water from a spray bottle on the leaves, install a humidifier in the room.

Failure to properly water is also a solvable problem. The regularity of watering is due to the time of year. IN summer time the irrigation procedure is carried out often, the soil should not dry out. But the abundance of fluid also causes negative processes. Due to stagnant water, the root suffers, rot may appear on it, as a result of which the stem also begins to rot, and the leaves begin to dry out. The middle is important here. Water only when needed. IN winter time, when the air temperature in the room is lowered, the soil is irrigated less often and plentifully.

If only the border of the leaves dries up, after which the entire area begins to darken and dry out, this indicates the development of any diseases that need to be fought with fungicidal preparations, otherwise the flower dies. If the leaves begin to curl, wrinkle, whitish spots appear on them, this indicates a possible defeat of their aphids. Treatment consists in treatment with insecticidal preparations, for example, Karbofos or Aktelik.

Why yellowing of the green mass occurs

The reason for this problem may be non-compliance with the irrigation regime. The result is that mold appears on the root system, the roots can rot. And if there is stagnation of fluid in the pan, a rotten root is noted, which may die in the future. How to save a dying flower? It is recommended to transplant it into another soil substrate, moderately moist. Do not water until the soil is dry. So there is a chance that the roots will recover. If the roots are completely rotted, most likely, the plant cannot be saved.

Another reason that the green mass turns yellow is the use of an unsuitable liquid for irrigation. If the water contains a large composition of chlorine and heavy metal oxides, the roots may become too thin, and the leaves begin to turn black or become covered with yellow spots. Proper watering should be carried out with such water, which was previously settled for three days. It is recommended to use melt or rain water for humidification.

If anthurium is grown, leaf diseases (photo), how to treat, it is recommended to know, because given plant is quite demanding on the conditions of cultivation and care.

Another reason for the yellowing of the leaves is the location in the place where the direct rays of the sun fall on them. Or vice versa, if there is not enough solar lighting there is such a problem. If you can’t move the pot to another place, it should be shaded. And if there is not enough light, artificial lighting is additionally installed. With a lack of soil substrate, it is recommended to transplant a flower, pour additional soil into the pot. If the cause was the activity of pests (aphids, mealybugs), it is recommended to use insecticidal agents to eliminate them.

Drying of hardwood

The reasons for this problem are increased dryness of the air or the presence of a draft in the room. To increase the humidity in the room, it is recommended to spray the flower two to three times during the day in summer and two to three times during the week in winter.

When irrigating, you need to be careful so that the liquid does not get on the buds. You can install a container with a flower on a pallet containing wet expanded clay.

Darkening of the green mass

If the leaves began to darken, while the roots also suffer, and the stem section is sluggish, this may indicate the presence of an increased concentration in the soil substrate of such a trace element as calcium. Excellent solution the problem becomes transplanting a flower into a better soil mixture with a balanced composition, selected specifically for epiphytes (for example, a soil substrate for orchids).

Fertilization must also be done correctly. It is not recommended to feed the soil too often, both roots and leaves can suffer from this.

Drying of leaf tips

The most common cause of this phenomenon is considered to be increased dryness in the room. Do optimal conditions for a plant, you can spray it abundantly with a spray bottle.

Do not place the container near heat sources. It is also important to ensure good aeration in the root system. Both the roots and the stump itself must receive enough oxygen. Such conditions can be provided by constant loosening of the soil.

Appearance of brown spots

The cause of this problem may be too low air temperature or improper fertilization. How many degrees should be in the room? At least 22C. Therefore, to eliminate the problem, you can additionally install heating. And for top dressing, use only specially selected formulations, which take into account the balance of essential nutrients, vitamins and microelements.

another reason brown leaves can become mealybug activity. To eliminate the pest, it is recommended to use insecticidal preparations (Karbofos).

With the right approach to growing, it will be possible to avoid multiple problems with anthurium.

Videos anthurium disease prevention

Anthurium was given to me by my sister after moving to new house- ostensibly it absorbs bad smells after repair. I spent a long time unpacking things and laying them out in new furniture, so I abandoned this flower ... But in vain!

This handsome man loves care very much, so he immediately fell ill from my “ignorance”. Fortunately, I caught myself in time and realized what was wrong with him. Now it blooms, surrounded by almost round-the-clock attention, and I hope it never turns yellow again.

• Infectious. Their pathogens are pathogenic viruses, fungi and bacteria. Just as the virus quickly spreads among the people in your office, it will start jumping from flowerpot to flowerpot. Therefore, at the first sign of infection, take the flower pot to another “quarantine” room, and for the rest of the plants (not only anthuriums), conduct a rigorous inspection and often ventilate the room in which they are located.
• Non-infectious. These are nursing mistakes. Flowerpots - neighbors will not be harmed by such anthurium diseases, and if they also get sick, it means that you watered, fed, transplanted all your pets in the same way. But if you understand your mistake in time and correct it, the plants can be saved.

Diagnosis by external signs

Not everyone likes to grow male happiness, as this flower is whimsical. A little something is wrong - and the leaves are already drying or turning yellow ... Moreover, the reasons for the same yellowing can be different (or vice versa, the reason is the same, the symptoms are different). I will describe them all, and you will figure it out on the spot.

Leaves turn yellow

• The flower "sat" in waterlogged soil for a long time. Things are bad: the roots have begun to rot, and if this process is not stopped, the flower will die. Take out the roots, terribly carefully pick the soil (you can wash it off warm shower, but with minimal pressure), cut off the rotten roots - they are not white, but brown and soft. Rub the cut points with charcoal.
• You did not defend water for irrigation. Because of this, a lot of chlorine got into the soil. Change the soil, continue to defend the water.
• You have overfed the plant. Excess fertilizer from the soil must be washed: pour the flowerpot with clean and warm water, making sure that all excess water flows out. Do not fertilize the anthurium for about a month. And of course, add less fertilizer (for this type of home flowers, you need half the rate indicated on the package).
• The plant has outgrown its pot and the roots are cramped. Move him to a new "house". It should be shallow, but wide. After relocation, you can water the flower with Kornevin.
• Sun problems. They can be radically opposite: either there is too much light and it is directional, which causes the leaves to burn (at first they are yellowish, then they turn brown and dry), or now the off-season and there is not enough light for the anthurium (buy a phytolamp, it will illuminate the flower inexpensively, constantly and carefully, without overheating it).

The leaves went yellowish (colored) spots

• It is quite possible to “thank” harmful insects for this. For example, a shield. She hides from the inside of the sheets, together with her larvae, sucks the juice from the leaves, and the poor things turn yellow from this, and in small areas, because the insects are tiny. But if there are a lot of them, the whole sheet is covered with “ripples”. There is only one way out: urgently exterminate the villains by washing the plant with green soap. There are other ways, they have already been discussed on this site.

Leaves turn brown

• Again, the overflow may be to blame. It is better for male happiness to feel frequent thirst than to “swim” in puddles.
• The soil is not suitable. You can suspect such a reason for the darkening of the leaves after transplanting, or buying a flower (in stores it does not always grow in the soil that it needs). For anthurium, you need to take flower soil and polystyrene chips. Also, many flower growers buy soil for this plant intended for orchids or bromeliads. Finally, you can mix 1 share of peat, coniferous, leafy soil and 0.5 share of sand.
• One of the roots is injured (say, during transplantation). To make it heal faster, keep the flower pot in a bright, warm place. You need to water it with warm water (30 degrees) and a little bit.
• The plant was watered with unsettled and/or cold (ice) water. Just stop doing it.
• The roots are supercooled, the flower is frozen. Is the room below 18 degrees? Move it to a warmer room.

• This is septoria (pictured). The disease can be recognized by the characteristic brown, grayish spots, as if surrounded by a yellow border. If you look closely at the spot closer, black dots are visible in it. Cut off diseased leaves, feed the soil, reduce air humidity. If everything is very bad, treat the plant with Fitosporin. Treat other flowers just in case with Bordeaux mixture.
• The plant was attacked by aphids (it sits at the bottom of the leaf, from above it appears as a scattering of small brown dots). Washing the leaves with soap or tobacco infusion will help you. A more effective substance in this case is Karbofos or Aktellik.

black spots on leaves

• Is the air too dry or hot? Isn't the pot standing next to the "burning fire" battery?
• Draft. This is the worst enemy of anthurium. For this flower, you need to choose the most comfortable corner in the house.
• This sunburn, and running. If you leave for work and don't see how the sun illuminates the pot at noon, just in case, shade it by placing a film on the glass - or simply move the pot deeper into the room.
• The room temperature is below 18 or above 28 degrees.
• The soil is saline due to irrigation. This can be seen from the whitish limescale on the soil, and even on the walls of the pot. Replace all the soil or at least it upper layer, and continue to defend the water throughout the day.
• Anthracnose. A disease in which drying begins at the edge of the leaves, then they wither, and finally die completely. Only a fungicide can cure your pet.

The leaves are curling

• The flowerpot froze in the draft. The leaves from such a life will not only curl up, but also dry up or wither.
• Something is wrong with the light: it is either too little, or vice versa, too much, and it burns the leaves - and not locally, but everywhere.
• You often water the flower, but forget to spray, and the air in the room is dry. The good news is that if you fix all this, the plant will not only move away, but also begin to bloom.

White bloom on leaves

• You watered the plant with chlorinated water without defending it.
• The flower was attacked by pests or disease. It can be: gray rot, powdery mildew, thrips. In this case, plaque may appear and only from the inside out - look for pests in the same place. How to treat a flower? Buy Bordeaux liquid or Topaz.

The plant does not bloom, and develops slowly

• Little light.
• Little food. This can also be told by leaves that grow too small, or too pale.
• It's cold in the room.
• If the leaves wither, this is a sign that you are overwatering the flowerpot.

Flowers on a healthy plant do not have time to bloom, as they immediately fade

• Do you take your pet outside? The fact is that what we call flowers is actually just an "airfield" for bees and others. beneficial insects, which should pollinate the stamen. And once they've done their job, the big colored petal won't be needed anymore, so it'll fade right away. This "diagnosis" is confirmed if the pistil of the flower turns into something like this:

Therefore, do not let insects get close to your flowers, and they will delight you for a very long time.

Hearing about such a large list diseases (and these are just leaves, we’ll talk about roots next time), many may exclaim: what kind of plant is this, what kind of care does it need? In fact, everything is not very difficult.

Yes, male happiness (like all men) has its whims, but any woman can fulfill them. I offer a video in which an experienced florist will tell you how she copes with her handsome man. Everything is very detailed and sensible:

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, knowledgeable features flower, consider anthurium very unpretentious and grateful houseplant. 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 long-term violation of the conditions of maintenance and care, plants are at risk of being affected by rot and fungal diseases that threaten, if not taken. urgent action, the death of 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, the lack of sunshine no, plants are more comfortable in partial shade.

The appearance of spots on the leaves of anthurium, the florist may be due to direct sunbeams, burning sheet 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 when the sun is most active, any impromptu screen can 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 anthurium on the leaves brown spots, dry areas and yellowness.

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 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 rounded or irregular shape, which gradually expand, acquire a brown color 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 use liquid ready-made funds, which are used weekly to restore a damaged plant, using a 25% 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.
