The tips of the leaves of anthurium dry out
Often, flower growers are faced with the problem of drying out the tips of anthurium leaves, which causes justified concern. The tips of dried leaves lead to a rapid increase in the area of damage to the leaf plate and complete loss of the leaf. The plant can lose all the leaves if it does not react in a timely manner and make changes in agricultural technology.
Understanding the reasons why leaves dry in anthurium will allow effective treatment. Dried tips of the leaves indicate insufficient humidity in the room. Another common cause is poor aeration of the root system.
Treatment of anthurium with dry leaf tips is more frequent spraying. A pot with a houseplant is placed away from heating radiators. A container of water is placed next to the pot to increase the humidity of the air.
Aeration of the root system depends on the composition of the soil and the material from which the flowerpot is made. The dense soil and the insufficient size of the drainage holes do not allow the roots to "breathe". Anthurium should be transplanted into a clay pot
It is important to use a special composition for epiphytic plants for planting.

The genus of anthurium contains up to 900 (according to some estimates, up to 1500) species and is deeply appreciated by lovers of indoor flowers of the Aroid family (this includes plants such as alocasia, philodendron, monstera, syngonium, scindapsus, zamiokulkas, dieffenbachia, aglaonema, spathiphyllum, anubias, colocastocoria etc.). All types of anthuriums are loved for their beautiful leathery, shiny, large leaves and unusual-shaped flowers that resemble sailboats.
Ornamental species are usually grown at home, including Hooker's anthurium, Veitch's anthurium, crystal anthurium, climbing anthurium, which is used for vertical gardening. The most popular are Andre's anthurium and Scherzer's anthurium, in which the inflorescence is characterized by a pronounced veil.
Anthurium is a wayward plant. To grow it and maintain a well-groomed appearance, it is necessary to use special soils, which will, moreover, be filled with substrates (they can be made at home on your own or purchased in specialized stores), have a drainage system, because this plant does not like being flooded or overdried , therefore, an optimal soil care system must be present. In nature, anthurium grows in loose soil with the remnants of rotted wood, which is constantly ventilated and is not oversaturated with moisture. However, at home, it is advised to use soil for orchids or violets (coal, peat, bark or sphagnum) with the addition of high-moor peat, perlite and leaf humus. Instead of high-moor peat, you can use store-bought, but not purchase low-lying soil, because it is completely unsuitable for growing anthuriums.
If the rules for choosing and caring for the soil are followed, the plants will delight you with their extraordinary beauty, otherwise, if the soil is oversaturated with water, improper care, and not following the appropriate criteria for room care and location, anthurium can "pick up" a viral disease, suffer from rot in roots, stems, parasite infestation. How to check if everything is in order with your anthurium? If you notice cracked leaves, blotches of yellow spots, bumps, white rot on the roots, yellowing, falling leaves, then the rules for keeping the plant have been violated.
Why is this happening and what to do?
Wrong temperature
Anthurium is a plant from humid hot countries.In winter, the optimum temperature for the viability of a flower is only eighteen degrees, and in summer, despite the flower's homeland, it is considered normal if the mark on the thermometer does not exceed twenty-six degrees. At the same time, anthurium does not like drafts and easily freezes on them.
If, nevertheless, the leaves began to dry out due to the wrong temperature, it is urgent to create comfortable conditions for the anthurium: rearrange it to a colder / warmer place, where no drafts can reach the flower - this is monitored especially carefully.
Important! It is imperative to reduce watering if the flower freezes.
Illiterate watering
Having found that the tips dry out due to the quality of the water, due to too many salts and heavy metals in it, you need not hesitate and switch to watering with another liquid with a better composition. A variant with water infusion is possible: running water is poured into a bottle and costs two to three days. After a few days, you can use it for watering: the composition improves, the liquid becomes less harmful. The main thing is that the water is at room temperature.
Pests
Anthurium is often attacked by ticks, scale insects or mealybugs. Having found traces of insects on the stem, leaf plate, leaf stalks and axils, flower growers treat anthurium with soapy water. A gram of nicotine sulfate is added per liter of water. A day after treatment, the plant is washed with clean water. Pre-growers take care of protecting the soil from waterlogging during the procedure.
In the fight against parasites, a solution of feverfew, tincture of tobacco or "Karbofos" can also help.
Fungus
It affects not only the leaves, but also the root system of the plant. When dry spots appear all over the leaf, the anthurium is removed from the pot and its roots are examined (for more details about the reasons for the appearance of various spots on the leaves of anthurium, we talked here)
If they suddenly turn from white / light brown to brown or black, and the tissues are soft and slimy, then the plant is transplanted, but before that it is important:
- remove soil residues;
- cut off damaged leaves;
- cut the roots affected by the fungus to healthy tissues;
- process the sections with crushed coal;
- treat the entire plant with a fungicide.
After moistening the soil, excess liquid is poured out, and until the next watering, the top layer of the earth is waiting for drying.
Pot does not fit
Anthurium, the reason for the drying leaves of which was the lack of free space in the pot, and therefore the lack of oxygen, requires an emergency transplant. The new container should be two to three centimeters larger in diameter, it is advisable to add more coarse fraction to the soil: cones, pieces of brick or charcoal.
If desired and at the right time, the plant is rejuvenated and planted.
Lack or excess of fertilizers
Violation of the feeding regime and their quantity leads to drying out of the tips of the leaves of the anthurium. If this happens, it is necessary to check the recommended rate and the amount of fertilizers usually given to the plant.
Excess nutrients in the soil cannot be corrected. In this case, the plant is transplanted into a "poorer" soil and the recommendations for the use of dressings are strictly followed. The disadvantage is compensated by an increase in the dose of top dressing.
Ground not suitable
Too dry soil or, conversely, waterlogged soil can lead to unpleasant consequences for the anthurium, up to its death
Therefore, it is important to observe the watering regime and not flood the anthurium. It is necessary to remove excess accumulated water from the sump on time, monitor the quality of drainage and dry air
Drying fast the substrate indicates dry air... Then they try to moisturize it in every possible way:
- spray the plant with water at room temperature;
- wipe the leaves (but you must not allow the lingering drops on the leaf plate - anthurium can burn);
- set off the plant, because the sun's rays, especially direct ones, not only harm the leaves, but also dry the earth.
In summer, it is recommended to place the pot on a wide base with wet coarse sand or pebbles. When watering with tap water, the composition of the soil can change, the same effect is given by an excess of fertilizers. In the first case, the anthurium is watered with water that has been infused for several days, in the second, it is transplanted and then the amount of dressings given is monitored.

Causes of blackening of anthurium leaves
Improper care and temperature conditions for the location of the plant often lead to the fact that the leaves of anthurium turn black. To figure out what reason influenced the plant, all possible ones will be analyzed in detail in the article.
Sick anthurium
Diseases
A variety of diseases can appear in both indoor and garden crops. Not insured against diseases and anthurium. If the leaves have dried up, spots, plaque have appeared, then such a plant should be quarantined until it recovers, so as not to harm the rest of the flowers. Treatment should be started as soon as possible.
The first possible problem is rust. It begins to appear first on the stems and leaves, looks like brown spots of different sizes. As a result, the leaves fall off, and the plant, after some time, completely disappears. This happens in dry air.
Septoria is a fungal disease that actively develops in a warm and humid environment. Yellow spots and brown edges appear, the leaves dry out quickly.
Soil fungi attack the roots, which rot and wither. The appearance is associated with the use of infected soil, or the plant was infected already upon purchase. Excessive watering and inadequate drainage in the pot are also causes.
For your information! If you do not deal with the treatment of the flower, removing the affected parts, then only a stump will remain from the plant.
Powdery mildew appears white. Distinguish between false and real. The latter is treated with fungicidal agents. It appears due to high humidity at high temperatures, sudden temperature changes, improper care. When pale small pimples appear, treatment for mealy fungi should be started.
Fusarium and gommosis are also found in anthurium. The reason is poorly disinfected soil.
Affected leaves
Anthurium can also turn black from the cescospore fungus. It is not as harmful to the plant, but it can affect its appearance. At first, it manifests itself in the form of yellow spots, which then turn into brown color, as a result, the leaves dry up and fall off.
Pest attack
Another reason why the leaves of anthurium turn black is the attack on it by pests. The main parasites are scale insects, aphids, thrips, and spider mites.
The scale insect is a tiny armored bug that is very difficult to spot. Careful plant care must be taken. These bugs deprive the indoor flower of energy, as a result, it fades and dies.
Thrips larvae can be seen on the back of the leaf, they look like black dots. They can infect the plant at any time of the year, but are more active in spring and summer. Larvae and adult thrips are also dangerous.
Important! All flowers affected by pests must be quarantined. The main signal for the appearance of aphids is leaves that are sticky to the touch.
Aphids are an insect that multiplies very quickly throughout the plant.
The main signal for the appearance of aphids is leaves that are sticky to the touch. Aphids are an insect that multiplies very quickly throughout the plant.
If a cobweb is seen on a flower, it means that a spider mite has settled on it. It leads to the drying out of all parts of the anthurium - leaves, flowers, shoots.
Incorrect fertilization
From the use of fertilizers in which there is a large amount of calcium, black spots may appear.Lack of boron, zinc and iron and an excess of calcium lead to rapid aging of the plant.
Anthurium should be fertilized in spring and summer once every 3 weeks. These flowers are very sensitive to both excess lime and excess minerals. Therefore, top dressing should be diluted.
Improper watering
Leaves darken at the edges when not properly watered. Watering with cold tap water and with an increased lime content in it is unacceptable. In summer it is watered with warm water at room temperature, in winter the water temperature should be 18 ° C.
Watering
What other spots can appear on anthurium and why
The appearance of uncharacteristic spots on the leaves of anthurium indicates a disease of the species. It is possible to understand the reason and decide on the treatment only after a thorough examination of the leaf plate.
Yellow spots
Yellowing of the leaf plate can occur when the plant is infected with chlorosis. It appears due to the lack of the following trace elements: iron and magnesium. For treatment, the damaged leaves should be removed and a complex fertilizer enriched with the necessary substances should be urgently introduced into the soil.
Yellow spots
On a note! It is possible to make an accurate diagnosis by the appearance of the sheet. With chlorosis, the veins remain green, and the leaf turns completely yellow.
Black spots
If the transplant procedure was carried out incorrectly or an unsuitable substrate for this type of substrate was used, black spots may appear on the anthurium.
The soil for this species is selected taking into account the individual preferences of the plant. For example, intended for bromeliads or orchids.
Blackening of the leaf
White spots
When anthurium is infected with powdery mildew white bloom appears on the leaves.
This disease occurs at high temperatures and high humidity in the room.
This disease is easily treated in the early stages with common fungicides.
Powdery mildew
What to do if the leaves of anthurium are covered with brown spots
If the leaf plates of the plant began to turn brown, you need to determine what exactly led to the appearance of this symptom, and start treating the anthurium:
- Incorrectly selected soil characteristics - transplanting into the right soil.
- Sunburn - moving the pot to partial shade.
- Improper Watering - Adjusting the watering schedule.
- Pest attack - the use of folk remedies or insecticides.
- Damaged roots - transplant with the removal of bad roots.
Additional Information! Drafts can cause brown spots on the plant. During the ventilation of the room, it is recommended to take the anthurium to another room.
In order not to face diseases, it is necessary to immediately establish proper care for the anthurium.
What to do to prevent diseases and pests?
The foliage turns yellow and falls off after fungal diseases. The most common:
- septoria;
- downy mildew;
- rust;
- anthracnose.
Disease prevention includes
- regular wiping of the leaves with a damp cloth;
- creating comfortable humidity by spraying water from a spray bottle;
- maintaining the correct temperature regime.
Wet, non-drying soil is a favorable environment for fungi and putrefactive bacteria. Anthurium does not like both insufficient watering and excess moisture.
Due to the aging of the flower, brown spots and drying of the leaves are considered normal. It is necessary to eliminate errors in care and provide normal growth conditions. When brown spots appear due to fungus and pests, the flower is treated with special preparations. Disease prevention and preservation of the attractive appearance of anthurium are achieved with good care and maintenance.

What are the diseases of Anthurium and the reasons for their occurrence
Violation of sanitary standards
The root cause of the onset of diseases is the attitude of the owner to the acquired houseplant. A flower needs time to adapt to new conditions. The plant must be monitored individually to exclude the presence of infection.
To keep your flowers healthy, you need to isolate all newly acquired indoor plants for 2 weeks from other crops, keep them in quarantine conditions. During this period, healthy plants will adapt and 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.
Non-communicable diseases are the result of a violation of the content of a flower in conditions that do not meet its requirements. Such diseases do not affect other plants. When the source of the disease is removed, they recover without harming other crops.
Infectious diseases cause pathogenic infections that invariably affect other plants. Changing hosts, pathogenic fungi, bacteria and viruses multiply rapidly and in a short time are able to destroy almost all nearby plants.
Plant care
The air around the plant should be well humidified. It is required to spray it a lot and often, and sometimes wipe the foliage with a damp cloth. To strengthen and develop the growth of adventitious roots, you need to overlay the stems with moss. If you follow all the requirements, anthurium will bloom magnificently all summer.
In the spring and summer, the flower grows, it must be fed, fed every 15 days, alternating organic and mineral fertilizers. The flower is transplanted annually in the spring (if the base of the flower is more than 25 cm wide, the transplant should be carried out every six months).
There are many reasons why flowers can become pale and small. This can be both a consequence of improper care, and one of the signs of the disease. Before starting active actions, you need to find out the cause, and then effectively eliminate it.
Fungal diseases
As mentioned above, anthurium is a moisture-loving plant, therefore it has a high chance of contracting 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 back of the leaf, you can usually see the formation of gray spores.
The source of this common disease is a microscopic fungus that is extremely sensitive to air humidity. The main condition for getting rid of this parasitic fungus is a decrease in air humidity in combination with the use of contact fungicidal preparations (Topaz, Acrobat).
Rust
The disease affects the leaves of anthurium. Chlorous spots of a rusty hue appear on the outer surface, and active sporulation occurs on the bottom. Just as in the case of downy mildew, the main method of combating and preventing leaf rust is to maintain optimal air humidity. For prevention, biological fungicides can be used, for example, Albit, Alirin, Fitosporin.
Anthurium leaf affected by rust must be treated with a fungicide
Fusarium wilting
This type of mycosis inhibits the entire plant as a whole. The fungal nature of the wilting of anthurium is produced by a pinkish-white bloom that forms on the root collar. The causative agent of the disease is species of fungi of the genus Fusarium (Fusarium).
Unfortunately, Fusarium infection 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 wilting suppresses the whole plant as a whole
Septoriasis
This common fungal disease manifests itself on the leaves with brown spots, sharply outlined with a yellow rim. In the future, the leaves wilt and the death of the plant occurs. The main treatment is the treatment of anthurium with copper-containing fungicidal preparations (Bordeaux liquid, copper sulfate, Cuproxat).
Brown spots with a yellow rim on the leaves of anthurium are a sign of septoria
Anthracnose
Another disease of anthurium, which has a fungal nature. The leaves begin to dry and thin out. Dry brown spots may appear at the edges or in the middle of the leaf blade. If urgent action is not taken, the plant will dry out rather quickly and will soon die.
With anthracnose, anthurium leaves begin to dry from the edges.
Treatment should be carried out with systemic fungicides (Fundazol, Acrobat, Ridomil Gold). And 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 spores of the fungus are extremely tenacious, so the vacated pot must be ignited. 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, but nightshade plants are more likely to suffer from this disease. Despite this, if you notice small spots of purple-brown color on the leaves, you need to urgently take action. Phytophthrosis develops very quickly and affects the root system, dooming the plant to a quick death.
The best option to combat late blight is to use systemic fungicides. Among them are 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 the pot or replace it with a new one. The roots can also be treated with a weak solution of potassium permanganate.
