How to deal with stains on anthurium leaves

When anthurium is healthy, its foliage has an even surface, characteristic of the variety, without traces of yellowness or dried spots. The leaves are quickly renewed, and the newly emerging ones unfold without difficulty and damage. This can be achieved by creating the conditions necessary for the growth of the anthurium and providing it with competent regular care.

Probable causes of drying and stains on anthurium leaves

Florists who know the features of the flower consider anthurium to be a very unpretentious and grateful houseplant. And yet, lovers of this culture sometimes have to face some problems, most often associated with:

• with errors in the organization of watering;
• in violation of the feeding schedule;
• with excessive dryness of the air;
• with improper plant lighting.

Slightly less often, the leaves of anthurium and he himself suffer from sudden changes in temperature and the content of the flower in a cold room.

As a result of a prolonged violation of the conditions of maintenance and care, plants are at risk of being damaged by rot and fungal diseases, which threaten, if urgent measures are not taken, the death of the pot culture.

Anthuriums can be attacked by harmful insects that damage both the root system of the crop and its aboveground part.

So why do leaves turn yellow on anthurium? And why do brown spots appear on the leaves?

Aging leaves of anthurium

Like other plants, the leaves of anthuriums 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 leaf plate, gradually covers it completely, the leaf loses its elasticity and juiciness, and then turns brown. If it is not removed, such a leaf of anthurium dries and falls off on its own. If the plant is kept in proper conditions, then the fall of old leaves does not damage the anthurium, because at the same time, new healthy foliage is actively appearing at the top of the stem.

Since the process is natural and inevitable, there is no need to worry about it. However, flower growers often have a question: "Is it necessary to remove yellowed or dry leaves of anthurium?"

Obviously, such leaf plates no longer fulfill their main function, but the plant spends certain forces on their maintenance. Therefore, it is better to cut off the leaves that have become obsolete, making life easier for the entire plant and making it more attractive.

To prevent the cut from becoming a place for the spread of infection, it is useful to treat the cutting tool, whether it be scissors or a knife, with alcohol, and sprinkle the damaged tissue on the anthurium with chopped charcoal.

If the leaf still retains its juiciness, you should not tear it off by hand, because this can seriously injure the stem.

In addition to natural reasons why anthurium leaves become stained or dry, growers have to face the consequences of mistakes they made when caring for a houseplant.

Spots on the leaves of anthurium due to excess or lack of light

The condition of the plant is strongly influenced by its location. Although in the tropics, where anthuriums are used to living in nature, there is no shortage of sunlight, plants are more comfortable in partial shade.

The appearance of spots on the leaves of anthurium, the florist may be due to direct sunlight, which burns the leaf plates. A deterioration in the appearance of a green pet cannot be avoided if the anthurium is in a rather dark place and suffers from insufficient lighting.

If the plant has stunted growth, blooms little and reluctantly, it probably lacks light. Anthuriums with dense dark green leaf blades are especially affected by this. Under conditions of short daylight hours or, being constantly in the shade, the cuttings of the leaves of anthurium lengthen, the leaf plates become smaller and noticeably pale. By rearranging the plant on a well-lit windowsill, you can see how it regains its former beauty, the development of yellowness and spots on the leaves of anthurium stops.

The main thing is, in an effort to provide the plant with the required lighting, not to overdo it and prevent sunburn.

When the pot is in direct sunlight, 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 tinted glass with a special film that reflects part of the solar radiation. If it is not possible to equip a window in this way, the plant can be moved from the glass, or at the hours of the greatest activity of the sun, put any improvised screen near the anthurium.

If you do not take urgent measures, excess sun seems not only on the color of the foliage, but also on its health. These are brown spots appearing on the tips of anthurium leaves, and the loss of damaged foliage.

Excessive dry air is the cause of dry leaves of anthurium

Similar symptoms can be seen in anthurium in a room with dry air. Most often, this reason makes itself felt at the beginning of the heating period, when the usual conditions for the plant change, and the aerial 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 don't have enough food. Yellowness spreads from the edges of the leaf plates to the center, then the tissue at the tips and edges of the leaves of anthurium dries. Young leaves that develop in dry air often fail to unfold properly and are deformed or damaged.

Additional air humidification is indispensable, and it is possible to achieve the required anthurium humidity of about 70-85% using a household humidifier, as well as improvised means. The plant reacts well if the pallet is covered with fine expanded clay and filled with water. The pot is placed on the litter so that the roots do not have contact with moisture.

Do not forget that a change in temperature and light conditions necessarily leads to the fact that the soil dries out faster or slower, and the plant also changes the mode of moisture consumption.

This means that the schedule will have to be changed. glaze... It is the improper moistening of the soil under the houseplant that most often provokes the formation of brown spots, dry areas and yellowness in anthurium on the leaves.

Anthurium leaves dry spots - the reason is watering

For anthurium, both insufficient watering and excess moisture are harmful. Especially sensitive to an excess of water are thick roots of the plant, which easily rot. Wet soil that does not dry out for a long time is an attractive environment for putrefactive bacteria, molds and fungi parasitizing plants.

Leaves are the first to react to irrigation disturbances and the problems caused by this. If a at anthurium leaves brown spots, this can be caused by moisture on the leaf plates. In the sun, such drops act as lenses and literally burn through living tissue.

It is even worse if the plant has been in a humid environment for a long time. In this case, tissue necrosis does not develop with spots on the leaves of the anthurium, but starting from the edges, spreads to the entire platinum leaf. You should try to dry the soil in a pot of such an anthurium, and with its increased density, which provokes the accumulation of moisture, change the entire soil.

During transplantation, be sure to examine the root system of the plant and remove all roots that are prone to decay.

For a plant that lives in a cool room, a violation of the irrigation regime threatens with fungal diseases.

Dry spots on the leaves of anthurium are the result of the activity of fungi

Like root rot, the spread of harmful fungi will inevitably lead to the fact that anthurium leaves dry in spots. At the initial stage of the disease, small yellow spots of a round or irregular shape can be seen on the leaf plates, which gradually expand, acquire a brown color in the center and begin to dry. The tissue at the site of the spot is subject to necrosis and may crumble, and concentric dark circles become visible around.

Brown spots on the leaves of anthurium are not the only symptom of the disease. The main damage caused by fungi and putrefactive microorganisms is the root system.

Therefore, when similar spots appear, the anthurium must be carefully removed from the pot and the roots must be examined. If the roots of a plant have changed from a white or light cream color to a brown or black hue, their tissues have become soft and slimy - this is a clear sign of root rot. Such a plant needs:

• remove residual substrate;
• cut off diseased and dry leaves of anthurium;
• trim all damaged roots to a healthy white tissue;
• process the cuts with crushed coal;
• and the whole plant is a fungicide.

After that, the anthurium is transplanted into a new soil, previously, like the disinfected pot.

The new substrate should be loose, so that any excess water can easily leave the soil and not harm the roots. After moistening the soil, the drained liquid must be removed from the pan, and until the next watering they wait until the surface of the ground under the plant dries up.

It is important to remember that for watering anthuriums, they take only settled warm water at room temperature.

Lack and excess of anthurium nutrition

If the plant has slowed down its growth, and its young leaves are smaller than the previously opened ones, it is likely that the anthurium suffers from a nutritional deficiency. Lack of basic elements such as nitrogen, phosphorus or potassium causes the leaves of anthurium to turn brown. A similar effect can be expected if the substrate lacks calcium or magnesium.

For feeding anthuriums, liquid ready-made products are used, which are used weekly to restore a damaged plant, using a 25 percent concentration of that recommended by the manufacturer. When the pet gains strength, you need to fertilize it every two weeks.

Sometimes not only a lack, but also an excess of 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 rinsing the root system.

Pests on the leaves of anthurium

Scabbard, all kinds of mites, aphids and mealybugs are those insects that most often cause damage to indoor anthuriums.

And for those who ask why the leaves of anthurium turn yellow, flower growers should carefully examine the stem of the plant, paying attention to the area near the ground, leaf stalks, their leaf plates and sinuses.

At the first signs of insects, anthurium is treated with ready-made complex insecticides or a soap solution, to which 1 gram of nicotine sulfate is added per liter of water. Since insect control agents are toxic, a day after treatment with them, the plant is washed with clean water, protecting the soil from excessive moisture.
