When anthuriumit is healthy, its foliage has a flat surface, characteristic of a variety of color without a trace of yellowness or dried spots. The leaves are quickly updated, and again appearing without difficulty and damage unfold. This can be achieved by creating the conditions necessary for the growth of anthurium and ensuring him competent regular care.
Probable causes of drying and stains on the leaves of anthurium
Flower growers who know the characteristics of the flower, consider anthurium to be a very unpretentious and appreciative houseplant. And yet, fans of this culture sometimes have to face some problems, most often related to:
- with errors in the organization of irrigation;
- in violation of the schedule feeding;
- with excessive dry air;
- with irregular plant lighting.
Slightly less often, anthurium leaves and he himself suffer from extreme temperatures and a flower in a cold room.
As a result of a long-term violation of the conditions of maintenance and care of the plant, they are exposed to the risk of rot and fungal diseases, which threaten, if not to take urgent measures, with the death of a pot culture.
Anthuriums can be attacked by harmful insects, causing damage to the root system of the culture and its above-ground parts.
So why leaves turn yellow at anthurium? And for what reason do brown spots appear on the leaves?
Anthurium leaf aging
Like other plants, anthurium leaves can turn yellow for a completely natural reason, due to old age. In such cases, the inevitable processes primarily affect the foliage located closer to the ground.
Yellowness, spreading from the edges of the sheet plate, gradually covers it completely, the sheet loses its elasticity and juiciness, and then turns brown. If it is not removed, this anthurium leaf dries and falls off on its own. If the plant is kept in proper conditions, then the fall of the old leaves does not cause damage to the anthurium, because at the same time, new healthy foliage actively appears on the top of the stem.
Since the process is natural and inevitable, it is not worth worrying about it. However, florists often have the question: “Should yellowed or dry leaves of anthurium be removed?”
Obviously, such leaf plates are no longer fulfilling their main function, but the plant spends certain forces on their maintenance. Therefore, it is better to cut off the outdated leaves, making life easier for the whole plant and making it more attractive.
To prevent the cut from becoming the site of the spread of infection, it is useful to treat the cutting tool, be it scissors or a knife, with sprinkled charcoal on the anthurium.
If the leaf still remains succulent, do not tear it off manually, because this can seriously injure the stem.
In addition to natural reasons why the leaves of anthurium become stained or dry, flower growers have to deal with the consequences of the mistakes they made when caring for a houseplant.
Stains on the leaves of anthurium due to an excess or lack of light
The location of the plant greatly affects its condition. Although in the tropics, where anthuriums are used to living in nature, there is no lack of sunlight, it is more comfortable for plants to be in partial shade.
The appearance of stains on the leaves of an anthurium grower may be required to direct the sun's rays, burning sheet plates. Do not avoid deterioration in the appearance of the green pet, if the anthurium is in a rather dark place and suffers from insufficient lighting.
If the plant has stopped growing, it blooms a little and reluctantly, probably it lacks light. Anthuriums with dense dark green leafy plates suffer especially from this. Under the conditions of a short daylight or, being constantly in the shade, cuttings at the leaves of anthurium are lengthened, the leaf plates become smaller and noticeably pale. Having moved the plant to a well-lit window sill, one can notice how it acquires its former beauty, the development of yellowness and spots on the leaves of anthurium stops.
The main thing, striving to provide the plant with the required lighting, do not overdo it and prevent sunburn.
When the pot is under the direct rays of the sun, flower growers are interested in what to do, because the leaves of anthurium turn yellow or acquire a bronze “tan”.
A good effect is provided by tinting glass with a special film reflecting part of the solar radiation. If it is not possible to equip the window like this, the plant can be transferred from glass, or in hours, the greatest sun activity is to place any improvised screen near anthurium.
If no urgent measures are taken, the excess of the sun seems not only on the color of the foliage, but also on its health. This and brown spots appearing on the tips of anthurium leaves, and the loss of the affected foliage.
Excessive dryness of the air - the cause of dry leaves of anthurium
Similar symptoms can be seen in anthurium, located in a room with dry air. Most often, this reason makes itself felt at the beginning of the heating period, when the usual maintenance conditions for the plant change, and the air roots and foliage can no longer receive the required amount of moisture from the air.
Why do anthurium leaves turn yellow in this case? They just do not have enough food. Yellowness spreads from the edges of the leaf plates to the center, then the fabric at the tips and edges of the leaves of the anthurium dries. Young leaves that develop in dry air often cannot turn around correctly; they are deformed or damaged.
Do not forget that a change in temperature and light conditions necessarily leads to the fact that the soil dries faster or slower, and the plant also changes the mode of moisture consumption.
So, it is necessary to change the irrigation schedule. It is the improper moistening of the soil under a houseplant that most often provokes the formation of brown spots, dry areas and yellowness on the leaves of anthurium on the leaves.
Dry leaves are stained with anthurium - the reason for watering is
Insufficient watering and excess moisture are harmful to anthurium. The thick roots of the plant, which easily rot, are especially sensitive to an excess of water. Wet, not drying out soil for a long time is an attractive environment for putrefactive bacteria, molds and fungi parasitizing plants.
The leaves react first to disturb irrigation and the problems caused by it. If of Anthurium has brown spots on the leaves, this may be caused by moisture on the leaf plates. In the sun, such drops act as lenses and literally burn through living tissue.
Even worse if the plant has been exposed to a wet environment for a long time. In this case, tissue necrosis does not develop in spots on the leaves of anthurium, but, starting from the edges, extends to the whole platinum sheet. The soil in the pot of such an anthurium should be tried to be dried, and at its increased density, provoking the accumulation of moisture, change the entire soil.
During transplantation, be sure to inspect the root system of the plant and remove all the roots that are prone to rotting.
For a plant that lives in a cool room, a violation of the irrigation regime also threatens fungal diseases.
Dry spots on anthurium leaves are the result of
fungus activity. Like root rot, the spread of harmful fungi will certainly cause the anthurium leaves to dry in spots. At the initial stage of the disease, small yellow spots of round or irregular shape can be seen on the leaf plates, which gradually expand, become brown in the center and begin to dry. The fabric in place of the stain undergoes necrosis and can crumble, and concentric dark circles become noticeable around.
Brown spots on the leaves of anthurium are not the only symptom of the disease. The main damage to fungi and putrefactive microorganisms cause the root system.
Therefore, when similar stains appear, the anthurium must be carefully removed from the pot and the roots examined. If the roots of the plant changed white or light cream color to a brown or black shade, their tissues became soft and skinny - this is a bright sign of root rot. Such a plant should:
- remove substrate residues;
- to cut off damaged and dry leaves of anthurium;
- trim all damaged roots to a healthy white tissue;
- process cuts with crushed coal;
- and the whole plant is a fungicide.
After that, the anthurium is transplanted into a new soil, preliminarily, like a pot that has been disinfected.
The new substrate must be loose, so that all excess water easily leaves the soil and does not harm the roots. After moistening the ground, the drained liquid must be removed from the pallet, and until the next watering they wait until the ground surface under the plant dries out.
It is important to remember that for irrigation of anthuriums take only separated warm water at room temperature.
Deficiency and Excess Nutrition of Anthurium
If a plant has slowed growth and its young leaves are smaller than those previously revealed, it is likely that the anthurium suffers from nutrient deficiencies. The lack of basic elements, such as nitrogen, phosphorus or potassium, leads to the fact that the leaves of anthurium turn brown. A similar effect can be expected if the substrate lacks calcium or magnesium.
For dressings of anthuriums, use liquid ready-made products, which are used to restore the damaged plant weekly, using a 25% concentration from that recommended by the manufacturer. When the pet gain strength, it should be fertilized every two weeks.
Sometimes not only a lack, but also an excess of fertilizers causes the development of yellow and brown spots on the leaves of anthurium. In case of an overdose of top dressing, it is better to transplant the plant into a new soil, after washing the root system.
Pests on Anthurium leaves 
And for those asking why the leaves turn yellow in anthurium, flower growers should carefully inspect the plant stem, paying attention to the area near the ground, leaf petioles, their leaf plates and sinuses.
At the first signs of insects, anthurium is treated with ready-made complex insecticides or soap solution, in which 1 gram of nicotine sulfate is added to a liter of water. Since insect control agents are toxic, a day after being treated with them, the plant is washed with clean water, protecting the soil from excessive moisture.
