Why do anthurium leaves have brown spots? Anthurium: care features, pests, diseases and their treatment Anthurium brown spots on leaves how to treat
The flower is quite unpretentious, resistant to diseases and pests, but sometimes problems arise for it too. Why do they appear on anthurium leaves? brown spots, why do they turn yellow and dry out? As always, these phenomena have three main reasons - not proper care, fungal and bacterial diseases, as well as insect pests. Another objective reason for yellowing and falling leaves is the natural death of old leaves with the simultaneous growth of new ones. This is not a disease, and nothing needs to be done about it.
Improper care
If brown spots appear on the leaves of the anthurium, they begin to wither, turn yellow and dry out, most likely it is not being properly cared for. To prevent the plant from dying completely, it is necessary to eliminate errors in watering, normalize the feeding schedule, optimize light, temperature and air humidity.
Anthurium does not tolerate sudden changes in temperature and prolonged exposure to a cold room. Short-term troubles in care and maintenance will not cause him significant harm, however, if they drag on, the plant is affected by bacteria and fungi, it stops developing normally, the leaves turn black and fall off. As a result, the anthurium dies completely. Before starting treatment, it is necessary to create the proper conditions for the anthurium.
Anthurium leaves also turn yellow with age; in this case, nothing needs to be done, and there are no measures that could stop the natural process. As a rule, the leaves at the bottom of the stem dry out and turn yellow. First, their tips turn yellow, then the yellowness spreads to the entire leaf; old leaves have to be removed so that they do not spoil the appearance of the plant. At the same time, new leaves grow at the top of the stem, and the flower is renewed.
Anthurium leaves deteriorate with too much or too little light; yellow or brown spots appear on them, which spread to the entire leaf blade. Anthurium prefers diffused light; direct rays of the sun cause brown spots to appear on its leaves - sunburn. If the anthurium is constantly on sunny windowsill, in summer, the glass can be covered with foil or a special tinting film.
Anthurium also suffers from lack of light. If it is constantly kept in a dark place, the leaves become faded and weak, which affects the general condition of the plant and its appearance.
In low light conditions, flower cuttings lengthen, leaves become smaller and fade - that’s why in winter it is necessary to additional lighting phytolamp or fluorescent lamps.
Dry air is another answer to the question: why yellow or brown spots appear on anthurium leaves and they fall off. In this case, the tips of the leaves first deteriorate, then the stains spread to the entire leaf, and it dries out.
Why is this happening? In conditions with low humidity, photosynthesis and metabolic processes in the leaves slow down, they do not receive adequate nutrition, all processes in them slow down, so they dry out and die.
Air humidity of 70-85% is considered normal for anthurium; to create it at home, you can place a container of water next to the pot, a tray with wet natural materials, for example with moss. If you put the pot in a tray with wet expanded clay or moss, you need to make sure that the roots of the plant are not immersed in water, as this will cause them to rot.
Brown spots on anthurium leaves also appear due to improper watering; the plant equally suffers from excess or lack of moisture in the soil. The roots of the flower are thick and large, so they easily rot from excess water; moreover, putrefactive bacteria and fungi multiply well in a humid environment.
Do not spray water on an anthurium that is in direct sunlight. Drops of water become lenses that concentrate streams of light, resulting in burns in the form of brown spots on the leaves.
Due to improper care, anthurim develops non-infectious diseases. For example, chlorosis is a consequence of a deficiency of magnesium and iron in the soil. appear on the leaves yellow spots, while the veins remain green.
Plant pox is another anthurium disease that occurs due to improper care. Or rather, because of the shortage useful substances, high air and soil humidity, low temperature.
Enation disease damages anthurium leaves, they become deformed and become covered with growths. These phenomena are also a consequence of improper care - high humidity, sudden temperature changes. After these factors are normalized, the disease goes away.
Rust on anthurium leaves can occur due to the use of aerosols to give them a glossy shine. Aerosols contain paraffin, which forms a thin film on the surface of the leaf and prevents the evaporation of moisture; if the plant reacts to the aerosol in this way, it cannot be used.
The leaves turn black due to improper replanting and damage to the roots. For planting and replanting, you need to use a soil mixture of coniferous, turf and leaf soil with the addition of sand. Or buy ready mixture for orchids and bromeliads.
Diseases
What diseases are you susceptible to? indoor anthurium? There are not so many of them, and it is necessary to fight them.
Anthracnose is fungal disease, which begins with the formation of brown spots with a yellow border in the middle of the leaf, they grow gradually, and if no action is taken, the leaf dries out completely.
Anthracnose develops in constantly moist soil with high level pH, as well as from a lack of potassium and phosphorus. What treatment is prescribed in this case? Damaged leaves are torn off, healthy leaves are sprayed with fucarcides. Treatment is carried out 3-4 times every 10 days. if the condition is neglected, the flower is completely destroyed.
Gray rot - with this disease, brown or brown spots appear on the leaves of anthurium. yellow, as well as gray plaque, which is nothing more than fungal micelles. The disease develops if the flower is placed in a room with high humidity and low temperature. Treatment consists of increasing the temperature, reducing watering, and removing and destroying damaged leaves.
If the disease is advanced and gray rot damaged the plant very badly, it is sprayed and watered with Oxyx and Topaz. The flower is transplanted into another soil, since fungal spores may also be present in it. The pot and soil are disinfected.
Septoria blight is a fungal disease that appears as brown spots on the leaves. Gradually, the spots increase, and the leaf blades turn black completely. Fungi spread very quickly, which is why damaged leaves must be removed immediately, and healthy ones treated with Alirin, Fitosporin or Bordeaux mixture.
Fusarium - with this disease, the leaves wither, turn yellow, dry out and fall off. A white-pink coating appears on the root collar, which is a colony of fungi. The disease develops due to high humidity; there is no treatment for fusarium; the plant must be destroyed. However, if the disease has just begun to develop, you can spray the bush with fungicides several times, and the soil is disinfected with a pesticide.
Rust is a fungal disease of anthurium, in which the leaves become covered with light spots on top and red-brown on the inside. Over time, fungal spores appear on the spots in the form of brown powder. To prevent the spread of the fungus and the death of the flower, at the first signs of disease it is sprayed with fungicides.
Pests
What insect pests attack anthurium most often?
Thrips, or small yellow midges, appear on the underside of leaves when air humidity is high. Thrips feed on plant sap, causing the leaves to dry out, become stained, and fall off. Thrips are also dangerous because of what they carry. viral disease– bronzed leaves. Leaves become discolored, deformed, and fall off. There are no remedies for bronzing of leaves; the affected plant must be completely destroyed, which is why it is so important to protect anthurium from thrips.
Spider mite- an insect that damages leaves. Mites originate in a dry, dusty room with a lack of fresh air.
The appearance of scale insects is indicated by white or yellow tubercles on the leaves. Insects suck the juice from the leaves, causing them to become deformed.
Aphids settle on the underside of leaves and feed on their sap. As a result, the leaves curl and a sticky liquid appears on them, which attracts other insects and harmful bacteria. If measures are not taken, the plant will quickly die.
The mealybug leaves behind “flour” on the leaves, which interferes with the processes taking place in them - moisture evaporation, metabolism and photosynthesis.
Pests are destroyed chemicals, and cover the plant with polyethylene in order to enhance their effect.
In addition, for the treatment of anthurium they use folk remedies– infusions of garlic, tobacco powder, yarrow. All plants located next to the affected anthurium must be treated; this will help localize the disease and prevent the appearance of pests on other flowers.
A beautiful indoor plant, popularly called “Male Happiness,” sometimes suddenly becomes covered with alarming brown spots. The reasons for their appearance on anthurium foliage and ways to eliminate the problem will be discussed in the article.
Reasons for the appearance of brown areas on the leaf plate
Often the appearance of brown spots on anthurium leaves is caused by improperly organized temperature regime and watering the plants. Also, the problem may arise due to the constant exposure of the flower to the sun, drafts, poorly selected soil and due to insect attacks.
Did you know?It is believed that “Male Happiness” not only affects the health of men and, by absorbing negative energy, brings harmony and harmony to the home, but is also able to improve the health of the air by absorbing such harmful substances like toluene and xylene.
Exposure to direct sunlight
Despite the tropical origin of anthurium, it cannot withstand direct solar lighting. If small brown spots are found on the foliage, this could be sunburn. They appear after watering, when drops of water falling on the leaves under the sun's rays turn into mini-lenses that concentrate solar energy and burning the leaf surface. In this regard, it is better to grow anthurium in light partial shade, remembering that lack of lighting also has a detrimental effect on the condition of the flower. 
Draft
Anthurium is sensitive to drafts - because of them, the leaves of the plant become covered with brown spots, which then turn black, and the flower fades.
Unsuitable room temperature
The heat regime for flower growth is between +18°C and +28°C. And if exceeding the norm does not have serious consequences for anthurium, then a decrease in temperature has a detrimental effect, which is manifested in the inhibition of its growth and the appearance of spots on the foliage.
Calcium salts in the soil
When watering a flower with hard water, calcium salts accumulate in the soil. This manifests itself as limescale on the surface of the substrate and on the walls of the pot. Excess calcium in the soil is also reflected on the foliage of the anthurium, which becomes covered with brown spots. To clean the soil from excess salts, you can remove top layer soil, replacing it with fresh soil mixed with peat or humus. 
For small containers, washing the substrate is suitable, for which soft water is poured into the pot, the volume of which is equal to the volume of the pot. Water, passing through the substrate and exiting through the drainage holes, carries with it most of harmful salts accumulated in the soil. In this case, it is necessary to ensure that after washing there is no liquid left in the pan.
Important! To avoid the accumulation of excessive salts in the substrate, the plant should be watered only with soft water, preferably rainwater.
Shields
The appearance of yellow-brown spots on the leaf surface of the anthurium is caused by the scale insect, which, absorbing juice from the leaves, deadens significant areas of them, leading to the death of the affected foliage.
Solutions to the problem
Brown spots on the foliage surface of a flower can also signal the appearance of root rot in the root system. If, after removing the earthen clod from the container, the roots in it, instead of being light in color, have a brown-black tint, it means that the root system is affected by a fungus or other putrefactive microorganisms. 
To fix the problem you should:
- Remove any remaining soil from the root system.
- Remove rotted roots with a knife, leaving healthy light roots.
- Sprinkle the cut areas with crushed charcoal.
- Trim leaves on the flower bush that are damaged by brown spots and withered.
- Treat the plant with fungicides.
- Transplant the flower into a fresh substrate and a new container, which are thoroughly disinfected beforehand.
To combat young scale insects, plants are treated and top part soil with a solution of warm water, grated garlic and laundry soap. It is also useful to disinfect the substrate with a solution of potassium permanganate, which not only disinfects the soil, but also fertilizes it. 
For adult scale insects covered with scutes, use similar products, as well as contact insecticides industrial production don't work. They can be removed manually using a sponge or soft toothbrush dipped in a solution. detergent for dishes. You can also resort to treating the plant with systemic insecticides in the form of “Confidor” or “Aktara”, 2 ml of which are dissolved in a bucket of water and sprayed onto the plant using a fine spray.
Plant care rules
Proper care of anthurium consists of: proper watering and feeding with fertilizers.
Watering
In its natural environment, a plant requires high humidity air and soil, so the same conditions must be created in the room where the anthurium grows. During the period of active growth, the flower is watered every 3 days, supplementing watering with daily spraying or wet wiping of the foliage. In winter, watering intensity is reduced to once a week. For irrigation use settled or filtered warm water. The plant is sprayed with the same water, being careful not to wet the flowers, which do not tolerate water well.
Important! Anthurium tolerates excess moisture just as painfully as it does overdrying the substrate, so stagnation of water in the tray should be avoided.
Fertilizer
During the growing season, especially during flowering, anthurium needs to be fed with fertilizers. In the spring, leaving the resting phase, the plant begins to increase green mass, for which it requires a lot of nitrogen. Best source of this element are organic fertilizers in the form of a solution of mullein or bird droppings.
Video: How and with what to fertilize anthurium
In the phase of budding and flower blooming, that is, from May to early October, anthurium requires fertilizers with a predominant content of phosphorus and potassium. Fertilizing in doses specified by the manufacturer is carried out at the root of the plant and combined with watering, which improves the digestibility of fertilizers and prevents burns to the delicate root system of the flower.
Other problems when growing anthurium
In addition to external factors, the plant is also affected by internal factors associated with age. As they grow older, the flowers become smaller and their color fades. The trunk becomes bare from below, losing dying foliage. In this case, the anthurium is rejuvenated using a cutting with 3 aerial roots. Sometimes the plant refuses to bloom. More often this is due to:
Did you know? It is believed that in addition to helping to improve health, anthurium is capable of attracting money, love and good luck in business to its owners during the flowering period.
If the spectacular appearance of an anthurium is overshadowed by the appearance of dark spots on its foliage, this is almost always explained by the gardener’s shortcomings in caring for the plant. Compliance with rules and care requirements, organization necessary conditions, guarantee the health and beautiful appearance of the flower.
Anthurium is special and very beautiful flower, which will delight you regardless of the time of year. It's blooming beautiful flowers red, pink, white and purple with a waxy surface.
However, anthurium is a plant that requires careful care, like any other indoor flower. The most common problem is anthurium diseases associated with its leaves. We will look at how they manifest themselves and how to treat them below.
What anthurium looks like: photo
In the photo in our gallery you can see what this flower looks like. He is very handsome refers to evergreens . Anthurium comes from the tropics, and its flowers have a special bizarre shape, which is why it is often called the flamingo flower.
Anthurium is very popular among amateurs and professional flower growers. It looks unusual in itself, and it can also be used in different ways in different flower arrangements and bouquets. If desired, you can find photos of examples of such combinations.
Another feature of the plant is that it can stand cut in a vase for several weeks in a row.
However, there are a number of anthurium diseases that affect the leaves of the plant. They cause owners a lot of trouble. Most gardeners believe that it is better to prevent them than to treat them after the fact.
Causes of yellow leaves
The key to beautiful anthurium flowering is proper care. If you neglect the rules and advice on this matter, the leaves of the plant will turn yellow. This is very bad, since such a phenomenon is not typical for anthurium.
Leaves turn yellow for reasons such as:
- care problems;
- chlorosis;
- sunburn;
- freezing of a flower;
- other diseases.
If you notice that the anthurium leaves have begun to turn yellow, then pay attention to how you water it. perhaps there is not enough water, or it's too tough. It could also be due to insufficient fertilizer or lack of sunlight. As a treatment, you just need to revise the watering schedule and rearrange the pot.
Yellowness diseases and treatment
If the anthurium leaves turn yellow due to a disease, then you need to identify it and begin the required treatment. So, if we are talking about chlorosis, then you need to spray the plant with iron chelate or algae extract. With this disease, the normal color of the veins is preserved, but the leaf turns yellow. Anthurium will also need more light.
Leaves may also turn yellow due to sunburn. This is why you can’t overdo it in terms of sun. A characteristic symptom is yellow or brown spots on the leaves, which then begin to curl and eventually dry out. The best treatment in this case, the flower will be moved to a dark place for some time.
You cannot place the anthurium in a draft and use it for watering too much. cold water. In this case, it may freeze, causing small white spots to appear on the leaves. In such cases, they need to be moved to warmer places.
Besides this, yellow leaves may indicate the presence of fungi. We'll talk about them a little later.
Why do anthurium leaves turn black?
Anthurium leaves can change color due to improper care. Brown spots may appear due to excessive watering. It is better to know when to stop in this matter, otherwise the plant will die.
Black and limp leaves are a sign of improper plant replanting. It is best to use a substrate for bromeliads or orchids, which will allow the flower to grow fully. It includes soils such as:
- coniferous;
- turf;
- leafy.
It also contains a sand-based mixture.
In addition to unsuitable soil, the cause of darkening of leaves during transplantation is root system damage, there is always a risk of damaging it, so read carefully in advance how to do this.
Sometimes diseases of the root system and anthurium flowers occur due to severe temperature changes. Brown heels and holes along the edges lead to the death of the plant, and there will simply be no time to treat. Therefore, it is better to take proper care to prevent this from happening.
What most often affects anthurium leaves?
Remove immediately sick plant from a healthy person, in order to avoid infection, you need to have the following symptoms:
- specific spots;
- plaque on leaves;
- dryness on both leaves and trunks.
Treatment in this case must be started immediately using special means to save the flower.
The most common fungal diseases of anthurium are:
- sooty fungi;
- gray mold;
- soil fungi;
- rust;
- and rot.
Fungal diseases of anthurium and their treatment
A disease such as rust mainly affects the stem and leaves. At the same time, brown spots appear on them different sizes. The leaves may then fall off entirely and the plant will rot. This can happen if the air and soil are too dry. For treatment and prevention, wipe the plant with Bordeaux mixture, and tear off rusty leaves and shoots and burn them so that other plants do not become infected.
Sooty mushrooms most often appear on the sugary secretions of aphids. They affect leaves, stems and young shoots of anthurium. Due to this disease, the plant cannot produce more shoots and its reproduction stops. In this case, the plant must be treated by cutting off the affected areas and treating the entire flower with potassium soap. This is what will remove the resulting plaque.
powdery mildew can be determined by white plaque, although it is divided into false and real. Treatment in both cases occurs with the use of fungicidal drugs.
This disease appears due to the following factors:
- high humidity at high air temperatures;
- sudden changes in temperature;
- problems with care.
Soil mushrooms provoke rotting of the forges, they can appear when the plant is transplanted into infected soil, as well as due to very abundant watering and poor drainage in pots. It is necessary to remove the affected parts of the anthurium in time and immediately treat the plant.
Gray mold is characterized by a gray coating on leaves and flowers. It is typical for young and weakened plants and appears as a result of being kept in unventilated areas, abundant watering, poor drainage and the fact that dry and dead parts were not removed in time.
Other common fungal diseases of anthurium include:
- fusarium;
- gommosis;
- caescospora fungus.
The latter disease is not as dangerous as others, but it is severe spoils the appearance of the plant, and colors its leaves first in yellow and then in dark shades.
- thrips;
- scale insect
It is very difficult to fight scale insects, since armored bugs are not visible at the initial stage of the disease. Only with careful care can the disease be cured. Bugs can cause the plant to wither and die, so if you notice them, you need to immediately apply insecticidal preparations and do mechanical cleaning plants.
Thrips can be identified by black spots on back side leaves. They can appear regardless of the time of year, but are especially active in spring and summer. Both adults and larvae are dangerous for anthurium. For treatment purposes, the flower is isolated from healthy ones and treated with an insecticidal solution. For prevention purposes, you should properly and regularly care for the plant and constantly ventilate the room where it is kept.
Enough Spider mites are also dangerous, if it is detected, you need to prepare for a long treatment process. The first sign of the disease is a thin web enveloping the leaves, stems and flowers. Then they dry out and curl.
The treatment will be like this:
- we clean the anthurium from cobwebs;
- wipe the pot and the surface on which it stood;
- Wipe the plant with laundry soap.
Don't forget to keep your plant in the right conditions, temperature and humidity must be optimal for its existence. The tick may return if care is taken.
It is, of course, better to prevent anthurium diseases than to treat them after the fact. In addition to observing the conditions of keeping the plant, you need to constantly inspect its leaves, flowers and stems for the appearance of spots and larvae on them, and also pay attention to changes in the shade of the leaves.
If everything is done correctly and carried out preventive measures, your anthurium will certainly delight you with its flowering.
Anthurium plant diseases
@alen.garden
Anthurium is a plant from the aroid family (Arumaceae), belongs to one of the numerous genera, numbering about 900 species. Translated from Latin name plants means "tail"; perhaps that is why it is also called the “flamingo flower”.
Description
Anthurium is native to the tropics and subtropics of America, northern Mexico, Paraguay and Argentina. The vast majority of species are erect herbs growing in tropical forests. With evolution, these plants turned into creeping plants - epiphytes and vines with aerial roots. Anthurium is also grown at home. It is popular for its spathes, which are shaped like a large petal that fits tightly to the inflorescence. The inflorescences form cobs in the form of thick tails.
Ornamental are beautifully flowering subspecies that have become commercially widespread. Used as a garden or cut plant and indoor plant. How does anthurium differ from other plants and what are its specifics? This is what we will talk about today.
Care
The first thing worth mentioning when discussing care rules is that the plant is poisonous. You need to be careful when working with a flower. Buy gloves that will protect your hands from the poisonous sap. Make sure that children or animals cannot reach the flower pot.
Room temperature
The main growing problem is foliage disease. Black spots appear on the leaves, they dry out and curl due to improper care or exposure to pests. To prevent this, you need to ensure optimal temperature conditions. This is 16–15 degrees in winter. In spring and summer, the temperature in the room can be from 20 to 25 degrees.
The plant should not suffer from drafts and wind; it needs to grow in conditions reminiscent of the warm climate of its homeland all year round. If you want the anthurium to start blooming earlier than usual, then gradually increase the temperature to 23–25 degrees. This is usually done in January.
Light
Anthuriums love good diffused light and tolerate shading well. Shading from direct rays is necessary, otherwise they will begin to appear on the leaves. dark spots or they will dry out. Place pots with plants on windows on the east or northwest sides.
Watering
Humidity should be high, especially in autumn and spring, when growth is most active. At the same time, it is necessary to provide abundant watering. Spray the flower using water room temperature. This procedure must be repeated twice a day. But do not allow water to stagnate in the soil!
The mistake many gardeners make when watering is overwatering, which provokes rotting of the root system. To prevent rotting, fill the pot with a drainage layer, which will control the level of liquid in the container. It is better to grow in a pot that is not too deep, but wide - the plant has a shallow root system. Due to the aerial roots, it receives the necessary moisture from the air, so wrap the roots with sphagnum moss, spraying it periodically.
Improper watering causes problems: dry leaves appear, brown and yellow spots appear on them, and the root system rots. Between waterings, the top layer should dry out a little. However, you should not allow the earthen coma to dry out. To ensure that the plant blooms profusely, reduce watering slightly in winter and autumn. Use soft rainwater. If you use tap water, it needs to be softened, as it contains a lot of lime.
Anthuriums love high humidity, from 85 to 95%. Many plants of this genus suffer from dry indoor air, especially species with brightly colored, thin leaves (majestic or crystal). To maintain the required humidity in the apartment, place the pot on a tray filled with wet gravel. Instead of gravel, you can use expanded clay. The pots can be placed in sphagnum moss, which should also be moist.
It’s not bad if you make an indoor greenhouse. It is better to wash off dust from the leaves with a soft sponge dipped in warm water. In summer you need to regularly spray the foliage with warm water, but with flowering you need to be careful with this. When spraying, make sure that drops of water do not fall on the flowers, as this will cause brown spots to form on them.
Top dressing
Don't forget about proper feeding. You need to fertilize in spring and summer, once every three weeks. Anthuriums are very sensitive to excess lime and minerals. Fertilizers should be diluted. As a complex fertilizer, use azofoska in a ratio of 1 g/l, adding potassium humate (300 mg/l). Foliar feeding is most effective on leaves.
Very good effect Organic fertilizers are also provided, but they are not always available. They need to be applied to the surface of the substrate. It could be leaf humus in the form of mulch or cow or horse manure (semi-rotted). Once a month you need to water it using an infusion of chicken manure or mullein.
For growth to be successful, you need the right soil. When growing in a pot, use substrates with a loose, coarse fibrous structure. The substrate must be breathable and have a neutral pH, from 5 to 6. The substrate must contain large particles that will hold the plant well and retain moisture and all nutrients.
The substrate should not quickly cake or decompose. No seals should appear here. Place at the bottom of the pot drainage layer, consisting of one layer of sand and cuttings. You can make a substrate from chopped moss (two parts), peat (two parts) and turf (one part) or deciduous soil and peat, adding a little coniferous tree bark. Due to poor-quality substrate, flowers and leaves may suffer: yellow spots appear on them, they curl and lose their shape.
Growing
Not very demanding. Not affected strong impact pests. IN industrial culture such plants are attacked by scale insects and scale insects, aphids and mites. Scale insects are dangerous for anthurium; they reproduce quickly, and serious efforts are required to destroy them.
Sick of root and stem destructive rots, which provoke an over-moistened substrate and too low temperatures. Anthracnose is another disease. How does it manifest itself? Dark spots appear on the leaves, they dry out at the edges. In case of severe damage, the anthurium is depleted and dies.
The fight against anthracnose is a serious process that requires persistence and time. You need to start treatment as soon as you notice the first signs mentioned above. Treat the plant with fungicides. You need to use systemic varieties of fungicide.
Problems with growth and darkening of leaves may appear due to excess calcium salts in the soil layer. Drafts, too dry air, lack of or excess lighting can also affect the appearance of the flower. If the tips of the leaves are dry, then the plant has received sunburn - just shade it. If the leaves darken or dry out in winter, then the whole point is a lack of lighting.
If you notice black dots on the leaves, then increase the temperature, as the plant is clearly freezing. Anthuriums love warmth. Problems with leaves can also arise due to improper feeding. The solution is to normalize fertilizing. If the spots are small and visible in the light, then most likely the plant is affected by spider mites.
In addition to mites, anthurium often suffers from scale insects, aphids, mealybugs, and septoria. Scale insects can be identified by sticky secretions on the leaves. As soon as you realize that the plant is sick, treat it with a soap solution. If the infection is severe, then use Karbofos for treatment.
Wrinkled leaves and yellow spots on them indicate aphid infestation. Here, for processing, use Actellik or tobacco infusion. Mealybug can be detected on the plant with the naked eye - its accumulations are located in the above-ground parts of the anthurium. Karbofos will help. If there is abundant spotting of foliage on the plant, then this is septoria. It is necessary to remove all affected foliage and treat with a regular solution of copper sulfate.
A bright solution for the whole year
Even inexperienced gardeners can provide anthurium with proper care and attention. Observe the required temperature conditions, proper lighting and air humidity, and then the anthurium will delight you with its bright appearance.

Anthurium or male happiness attracts the eye thanks to its magnificent inflorescences, painted in the brightest colors of the spectrum: red, purple, yellow, pink, blue. The glossy leaves of anthurium are also decorative, and some varieties are distinguished by a silvery frame of the veins. Anthurium is considered unpretentious plant, but for beautiful flowering and growth it needs certain conditions. If your plant looks sickly, analyze the errors in the maintenance and eliminate them, guided by our tips.
Optimal growing conditions
Anthurium moved into our apartments from the tropics of Central and South America, so I got used to shading. The best place in the apartment there will be window sills on the western and eastern windows for him. The optimal growing temperature is 16–20 °C in winter and 20–25 °C in summer.
Anthurium is a big lover of moisture. Like many tropical plants(zamioculcas, 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 when to stop. A wet substrate that does not dry out will quickly lead to rotting of the roots and death of the plant.
The soil for anthurium, as for most epiphytes, should be quite light and slightly acidic. Great option- ready-made special soil mixtures for aroids.
Important! All parts of anthurium, like most plants of the aroid family, contain poisonous juice, therefore it is necessary to isolate it from small children and pets.

Errors in caring for anthurium are usually easy to correct (replace the plant from the battery, water more or less, feed, change the windowsill, etc.), but to cope dangerous diseases and pests are not so easy.
Fungal diseases
As mentioned above, anthurium is a moisture-loving plant, so it has a high chance of becoming infected with mycoses. These are diseases caused by microscopic fungi that love moist environments.
Downy mildew (peronospora)
Whitish, yellowish spots appear on the leaves of anthurium, so familiar to gardeners. Cucumbers are often affected by this disease. The formation of gray spores can usually be observed on the reverse side of the leaf.
The disease affects anthurium leaves. Chlorotic spots of a rusty hue appear on the outer surface, and active sporulation occurs on the lower surface. The same as in the case of false powdery mildew, the main method of combating and preventing leaf rust is compliance optimal humidity air. For prevention, you can use biological fungicides, for example, Albit, Alirin, Fitosporin.
An anthurium leaf affected by rust must be treated with a fungicide.
This type of mycosis inhibits the entire plant. The fungal nature of anthurium wilting is revealed by a pinkish-white coating that forms on the root collar. The causative agent of the disease is species of fungi of the genus Fusarium.
Unfortunately, Fusarium infection occurs in many ways, including through water and air. And the fungal spores are extremely tenacious and resistant to high temperatures and chemicals. Therefore, the main thing in the fight against fusarium is prevention, for example, adding the antifungal drug Glyokladin to the soil. Systemic fungicides Vitaros, Rovral, Fundazol have also proven themselves in the fight against fusarium.
Fusarium wilt affects the entire plant
Septoria
This common fungal disease appears on the leaves as brown spots, sharply outlined by a yellow rim. Subsequently, the leaves wilt and the plant dies. The main treatment is the treatment of anthurium with copper-containing fungicidal preparations ( Bordeaux mixture, copper sulfate, Kuproksat).
Brown spots with a yellow rim on anthurium leaves are a sign of septoria
Anthracnose
Another disease of anthurium that is fungal in nature. The leaves begin to dry out and become thinner. Dry brown spots may appear from the edges or in the middle of the leaf blade. If urgent measures are not taken, the plant will dry out quite quickly and soon die.
With anthracnose, anthurium leaves begin to dry out at 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 protected. The fungal spores are extremely tenacious, so the vacated pot must be heated. If this is not possible, then you will have to get rid of such dishes.
Late blight
Anthurium is quite rarely affected by late blight; nightshade plants are still more often affected by this disease. Despite this, if you notice small purple-brown spots on the leaves, you need to take immediate action. Late blight develops very quickly and affects root system, dooming the plant to quick death.
The best option for controlling late blight is the use of systemic fungicides. These include Fitosporin-M, Fundazol, Alirin-B, Previkur. In this case, you will definitely have to replace the soil, rinse the roots thoroughly 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 damage
There are a huge number of chemicals available for the control of aphids; they can be purchased at any specialty store. The most famous of them are Aktellik, Fitoverm, Akarin, Aktara. You can also use a 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 indoor plants
This microscopic arthropod cannot be seen with the naked eye. Its size is only 0.5–1 mm. Nevertheless, such a baby can cause a lot of trouble. Spider mites feed on the sap of host plants. When infected by a pest, anthurium stops developing normally, the affected leaves turn yellow, which subsequently leads to the death of the plant.
Unfortunately, after 3-4 days the young growth will hatch from the soil, and the treatment will have to be repeated according to the same scheme. Anthurium will need to be treated 2-3 more times at weekly intervals.
Spider mites are clearly visible only under a microscope
Shchitovka
These harmful sap-sucking insects are a real disaster for indoor plants. Shields are reliably protected from external influence a special “shell”, so it’s not easy to get rid of them. Scale insects are visible to the naked eye. They cause the appearance of black spots on the leaves, wilting and subsequent death of the plant.
If you notice signs of anthurium being damaged by scale insects, place the plant in “quarantine” so that it does not infect its healthy counterparts.
To get rid of scale insects, they are cleaned by hand from the leaves and stems with a soft cloth. After this, it is necessary to treat the plant with special chemicals (Actellic or Fosbecid), following the instructions. Be careful - these drugs are toxic! It is better not to carry out processing indoors.

Thrips

Plants suffer not only from adult thrips, but also from their larvae and nymphs. optimal conditions thrips can double their population in 4–6 days. The main symptoms of thrips damage to anthurium are: rapid wilting, yellowing and dying of foliage
Anthurium resuscitation
Even if the anthurium has lost all its foliage, this is not a reason to get rid of it.
Living anthurium rhizomes can still be revived
First of all, you should find out what caused such a deplorable condition - improper care, disease 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 new soil in any available way:
- Steam treatment. The soil is laid out on a fine-mesh mesh over boiling water for 30–40 minutes. This is a labor-intensive but very effective method.
- Freezing. The soil is kept at sub-zero temperatures for a week, then brought into a warm room to thaw. This is a long process and is easiest to carry out in winter, when there is freezer you can use the balcony.
- Potassium permanganate. This is a method for the lazy. All you need to do is spill the soil with a raspberry solution of potassium permanganate and wait 30–40 minutes for the soil to dry.
