Why do anthuriums have brown spots on their leaves. Why are dark dry spots on the leaves on anthurium? Unsuitable room temperature

Amazing Anthurium! In nature, there are more than 900 species, and in room conditions most often contain Anthurium Andre, Anthurium Scherzer.

Anthurium impresses with its peculiar beauty. The leaves form a green bush, each leaf is shaped like a spade or a heart. The flowers stand out brightly and grow higher in level. From venomous red to tender white color– variety pleases the eye. The structure of the flower is very rigid, with a glossy or matte surface.

To make this flower with a tail (literal translation from Latin) delight you with a pleasant aroma all year round is worth the effort. If you do not keep the plant in "bliss", it is affected by various sores and pests: a fungus appears, the roots begin to rot, there are dark dry spots on the leaves.

The plant belongs to epiphytes. This means that more air should enter the soil, moisture should be retained, and excess water should leave. Use the soil of an orchid or azaleas as a base. It is imperative to add the following elements to it, create a substrate: pine bark, peat, sphagnum, perlite, any leafy or coniferous soil, sand with charcoal. Or just plant your anthurium in pure moss, without any additions.

How to please such an exotic? First of all, we create a certain microclimate. It's as easy as shelling pears - we imitate a tropical forest at home!

The well-being of the plant lies in a careful attitude:

It is necessary to exclude direct sunlight, only diffused light;

We maintain the humidity level. Spray the leaves (by no means flowers) twice a day in summer, less often in winter;

Watering on demand. Assess the condition of the plant's soil. If the soil is dry by 2 cm, you can water it. Approximately water 2 times a week in summer, 1 time a week in winter. Be sure to keep an eye on the excess water that is filtered into the pan - it must be removed in time;

We pamper with fertilizers: 1 time per week;

Temperature: 18-22 degrees. We protect from cold and drafts!;

The transplant takes place every two years. The substrate is gradually filled with roots and the plant becomes cramped;

The pot should be plastic - so the soil more easily reaches room temperature. And wide enough - for the growth of the root system;

After communicating with the flower, be sure to thoroughly wash your hands - the anthurium secretes poisonous juice.

The main problem of anthurium is dark dry spots on the leaves.

If your anthurium leaves are darkening, they overlooked somewhere.

Consider the standard causes and methods for restoring flower health:

Wrong watering. Determine if your “phytopet” gets enough moisture? Or perhaps you forgot about spraying? Spray twice a day, water once a week. Try also using a special humidifier;

The plant "suffocates" in the soil: the ratio of the elements of the substrate is incorrect. Try a layer of leaves or bark, a layer of softwood, a layer of peat, a layer of sand. Ratio 1:1:1:0.5;

Temperature: not only about the room, but also about the water temperature for irrigation! It should not contain lime, it is advisable to use cool, purified water;

Anthurium location: dark dry spots on the leaves in the absence of light, begin to increase literally before our eyes. Evaluate carefully all the conditions - the plant does not live well on the windowsill above the battery, in the kitchen, with an open window. Move the flower pot to the balcony, to a place with moderate light;

Fungal disease. In this case, you can inspect the roots, cut off the rotten ones. Dry the soil and move to another pot. Chilled leaves cut off and sprayed with special solutions.

In conclusion

Be sure to save yourself the advice of flower growers described above. Remember the plant maintenance formula: water moderately + spray more often. Loose soil + moist soil support + fertilizer. Diffused light + room temperature.

If a disease has happened to the plant, you will have to fuss. Inspect the anthurium carefully, the leaves darken gradually - from pale spots on the leaves to blackness around the edges. The situation is not hopeless. Depending on the cause of the disease, the conditions for keeping the flower should be changed. The main problems that the flower suffers from are flooding with water, lack of light, unhealthy soil.

Anthurium gratefully responds to the right attention from the owner. Arrows of leaves grow abundantly, flowers decorate the house for 2 months.

Treat the plant with love and respect!

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 there will be 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 like in the case of false powdery 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

It's 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 liquid, blue vitriol, Cuproxate).

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. indoor plants

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 Fosbecid), 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 preventive measures in time. possible diseases. If you take care of the plant correctly, then the anthurium will delight you the brightest flowers the most exotic colors throughout the year.

One of the reasons for the wilting and drying of the leaves is the banal aging of the flower. This is a natural process to which all living organisms are subject, without exception, and it cannot be stopped. The tips of the old sheet dry, then the entire plate acquires a yellow tint, after which it turns brown and dries. It is better to cut such parts of the plant - they do not perform useful functions, but at the same time they pull nutrients and moisture from the flower. Scissor blades should be pre-treated with alcohol or any other antiseptic so that the wound does not become a breeding ground for infections.

True, one can talk about aging only in those cases when only a few leaves turn yellow and fall off in a month. If a similar phenomenon is observed often and affects young leaves, the problem must be sought in diseases or care errors.

Wrong lighting

Some flower growers believe that if the anthurium comes from tropical countries He needs a lot of light. On the one hand, this is true, but partial shade is considered the optimal conditions for keeping a flower. Intense lighting can burn the leaves, causing brown spots to appear on them. For this reason, the anthurium should be slightly shaded from bright light, especially in the summer. A special film that reflects ultraviolet radiation gives a good effect - it must be installed in front of the pot in the form of a screen.

If, along with the yellowing of the leaves of the plant, it loses its natural bright shades and blooms reluctantly, then the situation is reversed - it lacks lighting. In this case, the anthurium needs to be moved closer to the light, and it will quickly return to its former beauty.

dry air

For normal growth, anthurium requires not only proper lighting, but also sufficient air humidity - at least 70-85%. If the air is too dry, the leaves will begin to turn yellow, dry and fall off, and new leaves cannot unfold normally, remain twisted and deformed.

Most often, a similar phenomenon is observed at the beginning of the heating season, when the air humidity drops sharply, and the plant can no longer receive moisture from the soil. To correct the situation, you can:

• use household humidifiers;
• put water containers next to the flower;
• pour drainage into the pan of the pot, fill it with water and place the plant so that its roots do not touch the water.

In addition, it is necessary to water the anthurium a little more often, but without flooding it too much.

The soil should be moist, but not swampy - excessive moisture harms the flower no less than lack of watering. Water the plant so that moisture does not fall on the leaves. Even small drops of water act like lenses - they focus Sun rays which causes tissue burns.

Wrong top dressing

To maintain a bright shade of leaves and an aesthetic appearance, anthurium needs top dressing, but an overabundance of nutrients is as harmful as their lack. The main trace elements required by the plant are potassium, phosphorus and nitrogen. In addition, brown spots often appear on the leaves of the atrium due to calcium and magnesium deficiency. For top dressing, ready-made nutrient mixtures are used, which are bred according to the instructions. For weakened plants, a 25% concentration is sufficient, but top dressing should be done every week.

fungal diseases

Fungal infection is one of the most common causes of yellowing of anthurium leaves. The spots appear on the central part of the leaves, gradually expand and capture the entire plate, which gradually turns brown and dries. When such a sign appears, you need to carefully remove the plant from the pot and inspect the roots - fungi often multiply on the root system. If they have changed shade, become soft and slimy, you should immediately begin to deal with the problem. For this you need:

• carefully remove the remaining soil from the roots;
• remove the affected leaves and roots with scissors that have been disinfected, and sprinkle the slices with crushed coal;
• spray the plant with a fungicide as directed in the instructions.

After that, it is necessary to disinfect the pot well and transplant the plant into fresh soil - it should be loose and nutritious. In the first time after transplantation, the anthurium will need careful care, otherwise the weakened flower may die.

Pests

If insects are found, the plant must be treated with tobacco or garlic tincture, as well as soapy water. If there are a lot of pests, it is better to use complex insecticide preparations. When working with them, care must be taken, and after a day, wash off the remaining solution from the leaves to protect the anthurium from toxic effects.

Let's summarize

1. Brown spots and drying of anthurium leaves are considered the norm only when this occurs due to the aging of the flower.
2. When brown spots appear on the leaf plates, it is first necessary to eliminate errors in care and provide the plant with normal conditions.
3. If the spots appeared due to fungal diseases or pests, you must immediately treat the flower with special preparations, otherwise it may die.
4. For the prevention of anthurium diseases and the preservation of its attractive appearance, it is necessary to provide it with good care and optimal conditions.

A rather unpretentious flower, resistant to diseases and pests, but sometimes it also has problems. Why do brown spots appear on anthurium leaves, why do they turn yellow and dry? As always, these phenomena have three main causes - improper 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.

Wrong care

If brown spots appeared on the leaves of the anthurium, they began to wither, turn yellow and dry, most likely, they are not properly cared for. So that the plant does not die completely, it is necessary to eliminate errors in watering, normalize the fertilizing schedule, optimize illumination, temperature and air humidity.

Anthurium does not tolerate sudden changes in temperature, and a long stay in a cold room. Short-term troubles in care and maintenance will not cause him significant harm, but if they drag on, the plant is affected by bacteria and fungi, it ceases to develop 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 anthurium.

Anthurium leaves turn yellow with age, nothing needs to be done in this case, and there are no such measures that could stop the natural process. As a rule, the leaves located at the bottom of the stem dry 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 appearance plants. At the same time, new leaves grow at the top of the stem, and the flower is renewed.

Anthurium leaves deteriorate with excess or lack of light, yellow or brown spots appear on them, which spread to the entire leaf plate. Anthurium prefers diffused light, brown spots appear on its leaves from the direct rays of the sun - sunburn. If the anthurium is constantly on a sunny windowsill, in summer the glass can be covered with foil or a special tinting film.

Anthurium also suffers from a 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, the cuttings of the flower lengthen, the leaves become smaller and fade - this is why in winter it is necessary to make additional illumination with a phytolamp or fluorescent lamps.

Dry air is another answer to the question: why do yellow or brown spots appear on anthurium leaves and they fall off. In this case, the tips of the leaves first deteriorate, then the spots spread to the entire leaf, and it dries.

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, such as moss. If you put the pot in a pan with wet expanded clay or moss, you need to make sure that the roots of the plant are not immersed in water, this will cause them to rot.

Brown spots on the leaves of anthurium 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 under the direct rays of the sun. Water droplets become lenses that concentrate streams of light, as a result, burns appear on the leaves in the form of brown spots.

Due to improper care, non-communicable diseases develop in anthurim. For example, chlorosis is a consequence of magnesium and iron deficiency in the soil. Yellow spots appear on the leaves, while the veins remain green.

Smallpox vegetable is another anthurium disease that occurs due to improper care. More precisely, due to a deficiency of nutrients, high humidity of air and soil, low temperature.

Enation disease damages the leaves of anthurium, they are deformed, covered with growths. These phenomena are also the result of improper care - high humidity, a sharp temperature drop. After the normalization of these factors, the disease disappears.

Rust on anthurium leaves can occur due to the use of aerosols to give them a glossy sheen. The composition of aerosols contains paraffin, which forms a thin film on the surface of the sheet and prevents the evaporation of moisture, if the plant reacts to the aerosol in this way, it cannot be used.

The leaves turn black and due to improper transplantation and damage to the roots. For planting and transplanting, you need to use a soil mixture of coniferous, soddy and leafy soil with the addition of sand. Or buy a ready-made mixture for orchids and bromeliads.

Diseases

What diseases are indoor anthurium susceptible to? There are not so many of them, and it is necessary to fight them.

Anthracnose is a fungal disease that begins with the fact that brown spots with a yellow border form 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 a high pH level, as well as from a lack of potassium and phosphorus. What treatment is prescribed in this case? Damaged leaves are torn off, healthy ones are sprayed with fucarcides. Processing is carried out 3-4 times in 10 days. if the state is running, the flower is completely destroyed.

Gray rot - with this disease, brown or brown spots appear on the leaves of the anthurium. yellow color, as well as a gray coating, which is nothing more than micelles of a fungus. The disease develops if the flower is in a room with high humidity and low temperature. Treatment consists of raising the temperature, reducing watering, removing and destroying damaged leaves.

If the disease is advanced and gray rot damaged the plant very much, it is sprayed and watered with Oksih and Topaz preparations. The flower is transplanted into another soil, since the spores of the fungus can also be in it. The pot and soil are disinfected.

Septoria is a fungal disease that manifests itself as brown spots on the leaves. Gradually, the spots increase, and the leaf plates turn black completely. Fungi spread very quickly, which is why damaged leaves must be removed immediately, and healthy ones should be treated with Alirin, Fitosporin or Bordeaux liquid.

Fusarium - with this disease, the leaves wither, turn yellow, dry and fall off. A white-pink coating appears on the root neck, which is a colony of fungi. The disease develops due to high humidity, there is no method of treating Fusarium, the plant has to be destroyed. However, if the disease has just begun to develop, you can spray the bush with fungicides several times, the soil is disinfected with a pesticide.

Rust is a fungal disease of anthurium, in which the leaves are covered with light spots on top, and red-brown from the inside. Over time, spores of the fungus appear on the spots in the form of a brown powder. To prevent the spread of the fungus and the death of the flower, at the first sign of the disease, it is sprayed with fungicides.

Pests

What insect pests attack anthurium most often?

Thrips, or small yellow midges, appear on the underside of the leaf when the air humidity is high. Thrips feed on plant sap, which causes the leaves to dry, become stained, and fall off. Thrips are also dangerous because they carry a viral disease - bronze leaves. The leaves become discolored, deformed, and fall off. There are no remedies for leaf bronosis, the affected plant has to be completely destroyed, which is why it is so important to protect the anthurium from thrips.

Spider mite is an insect that damages leaves. A tick is born in a dry, dusty room, with a lack of fresh air.

The appearance of a scale insect is indicated by white or yellow tubercles on the leaves. Insects suck the juice from the leaves, and they are deformed.

The aphid settles on the underside of the leaves and feeds on their juice. As a result, the leaves curl and develop a sticky liquid that attracts other insects and harmful bacteria. If you do not take action, the plant will quickly die.

The mealybug leaves behind "flour" on the leaves, which interferes with the processes taking place in them - the evaporation of moisture, metabolism and photosynthesis.

Pests are destroyed with chemicals, and the plant is covered with polyethylene in order to enhance their effect.

In addition, for the treatment of anthurium use folk remedies- infusions of garlic, tobacco powder, yarrow. All plants located near the affected anthurium are subject to treatment, this will help to localize the disease and prevent the appearance of pests on other flowers.

- This is a tropical epiphyte, ideal conditions for it are tropical rainforests. Therefore, at room conditions, this plant is capricious, very demanding on soil, irrigation regimes, temperature and air, but this does not stop exotic lovers.

Sometimes the flower is sick, spots appear. The sooner you understand the cause of brown spots on anthurium leaves, the more likely the plant is to be cured. We hope this article will help you figure it out.

Good care rules

Anthurium record holder in duration - with good conditions may bloom for three or more months. The plant is spectacular, bright, grows well and quickly, under certain conditions.

Since anthurium comes from tropical forests, it is necessary to organize for it:

• warmth and light
• soil and good nutrition

Proper watering

So, in order: warm, warm and warm again! Below 18 degrees - this is already the north pole for him, in addition to air temperature, soil temperature is important - it should not be lower than the environment. If the flower is on the windowsill, then in winter time fit a piece of fabric, cardboard or polystyrene under the planter so that the roots do not cool. Direct sunlight causes burns, in the shade it can grow, but will not bloom. He needs diffused light.

The soil

Special for anthurium is not for sale, so you need to prepare it yourself:

• take equal parts of the soil for the azalea,
• and baking powder
• add some pine bark and charcoal.

Anthurium is suitable for soil with an acidic environment, the soil for azaleas just meets these requirements. River sand is best suited as a baking powder, but any other (perlite, vermiculite) can be purchased at the store. To protect the roots from decay, drainage is necessary - at the bottom of the pot there is approximately a layer of 2-3 centimeters of expanded clay, broken bricks or small stones.

top dressing

Anthurium requires good nutrition - give it liquid fertilizer once every 2-3 weeks, but do not overdo it, otherwise it will turn yellow. To do this, take the dose of fertilizer recommended in the instructions three times less.

IN winter period reduced or not carried out at all. Once a month, add citric acid at the tip of a knife to the water for irrigation so that the soil is slightly acidified.

The soil should be breathable, it should not be stagnant water. With stagnation, the roots quickly rot and the flower may die in a few days. The soil should be moist, but not wet, the water from the pan should always be poured out. Watering should be done after the topsoil is slightly dry.

Difficulties in growing

Not all amateur gardeners manage to grow the first time. A flower bought in a store at home begins to wither, if all the leaves are damaged, then the flower almost always dies.

To prevent this from happening, you need the right transplant:

• It is better to transplant immediately after purchase
• Transplantation only by transshipment

Many do not advise immediately transplanting plants bought in the store, but in vain. The roots are cramped in such small pots, the sooner the transplant is, the faster the flower will get used to the new conditions.

Most often, the plant suffers due to improper care for it, especially with regard to air humidity. The optimum humidity in the room should be at least 70%, but it is very difficult to achieve such a figure.

Usually, in residential premises, it barely reaches 30%, which, by the way, affects not only plants, but also people, especially small children. Anthurium is very fond of spraying, while the water should not be cold, room temperature or a little hot is best.

By the time you spray the water, it will have had time to cool down to a comfortable temperature. This should be done every day. When spraying, you need to cover the flower stalks, it is not desirable that water gets on them.

Another difficulty is to organize the right one so that the flower does not dry out and does not rot. Some amateur gardeners recommend covering the soil with moss or even replacing the entire soil with it. It has a lot of nutrients, it holds moisture well, while preventing the formation of mold and root rot.

Under the right growing conditions, anthurium grows strong, rarely exposed to infections or pests. And if this happens, then with the right treatment, he quickly recovers.

Mistakes in care

A healthy anthurium is always with bright, juicy leaves, grows well and blooms on time; if you have such an anthurium, then you are doing everything right. If something does not suit the flower, then damage may appear.

Brown spots may appear if the plant:

• little heat - first brown dots appear, then they expand, forming spots, a draft also leads to a similar reaction
• direct sunlight causes a burn, the leaves may first turn yellow, then darken
• little water and dry air can also cause stains, there can even be holes from dryness
• a lot of water - the roots suffer from this, they cannot breathe, it affects the whole plant, spots appear, the roots begin to rot and all this can end badly
• there is not enough nutrition - deformation, yellowness joins the spots; with a lack of nitrogen, the lower leaves, young leaves grow weak, pale; lack of sulfur - the upper leaves turn yellow, excess - turn yellow along the edge, then the shade becomes brown, and they twist; deficiency or excess of manganese manifests itself in the form of point yellow spots, gradually the leaf wrinkles and falls off.

In order to cure a flower, you need to eliminate all adverse effects and create comfortable conditions. If there is little heat, then the flower should be placed in a warmer place, but not near the battery, if it is dry, water and spray more often, wipe off dust.

Brown spots most often appear from hypothermia and overflow.

If you realize that you have watered the plant too much and this causes brown spots on the leaves of the anthurium, what to do:

• stop watering and spraying, it is better to just wipe the leaves of the plant with a damp cloth
• observe if the spots appear in large numbers, then the roots are rotten and a transplant is required

Prepare the soil, treat it with a solution of potassium permanganate or fungicide. Carefully remove from the pot, clean the roots from the ground, cut off all the damaged ones (healthy roots are white and elastic), treat the cuts with charcoal (the pharmacy activated one is suitable), dry for an hour. Plant in new soil, top with moss. At first, spots may still appear, but not so intense. Water rarely and a little, the flower tolerates drought better than overflow.

Infectious diseases and pests

But sometimes it can happen that anthurium has brown spots on flowers, leaves appear even under all growing conditions. Then it is worth suspecting infectious diseases. Most often, the flower is affected by fungal infections, less often bacteria and viruses.

Fungal diseases that cause brown spots on anthurium leaves and how to treat:

• septoria - causes a fungus disease, with this disease the spots are dark, along the edges with a lighter or yellow tint. It is necessary to remove all affected leaves and treat with a fungicide. Phytosporin is suitable: 1.5 g per liter of water, spray, repeat after 10 days
• Fusarium - the causative fungus, infection is usually through the soil, the disease spreads from the roots, then the stems and leaves are damaged. You need to treat with a fungicide, the disease is dangerous, often everything Taken measures do not lead to recovery

What mistakes in plant care lead to the appearance of spots, what conditions anthurium needs for a good life, how to properly prepare the soil and how to get rid of pests and fungi, you can see when watching the video:
