Possible causes of spots on the leaves of anthurium and ways to get rid of them

For healthy leaves of anthurium or, as it is also called, a flower, male happiness is characterized by brilliance and uniform coloring corresponding to the variety. The appearance of any spots, dryness indicates a plant disease.

Causes of black patches on the sheet plate

Exposure to direct sunlight

Anthurium does not like the scorching sun, in the summer it must be shaded or put away on the table, which stands next to the window. This is especially true in the hot summer days.

Draft

Keep an eye on this and do not leave anthurium in the drafts during ventilation. It is better to initially put it in a place where, when opening the window leaves, no wind gusts from the street will fall on the plant.

Unsuitable room temperature

Being a thermophilic tropical plant, Anthurium perfectly tolerates summer temperatures up to + 28 °, if direct sunlight does not fall on it. Much worse, he suffers a cool.

With a decrease in air temperature, the leaves of Male happiness become covered with black spots, after which the plant dies rather quickly.

Do not allow a long stay of anthurium in a room with an air temperature below + 16 °, even in winter, it should be higher for this thermophilic flower.

The owner of the anthurium must carefully monitor the temperature regime and the absence of drafts in the room.

Soil calcium salts

If a suitable microclimate is created for the anthurium, and the leaves turn black anyway, the reason lies in the inappropriate soil. It must be replaced with a substrate for aroid, which can be bought in a store for gardeners or ordered via the Internet.

Also You can make a mixture of chopped moss, peat and turf land (2: 2: 1). A mixture in equal proportions of peat, sand and sheet soil is suitable, a small amount of charcoal or pine bark should be added to it. At 1/3 of the height of the pot, lay out drainage, for example, of expanded clay.

Shields

These are tiny insects that can settle on the leaves of anthurium. Because of them, small black spots appear in the form of dots.

1. It is necessary to carefully examine the plant, if it detects insects, it must be removed away from other indoor flowers.
2. The scab is removed manually with a cotton swab dipped in an insecticide solution.
3. After that, the leaves are wiped with a cloth soaked in soapy water with the addition of kerosene.

It’s unlikely to notice all the shields at a time, you need to re-examine the leaves and stems for several days.

Why is the plant covered with yellow dots?

Excess moisture in the soil

Do not turn soil in a pot into non-drying dirt. It is not necessary to wait for the land to dry completely, it is necessary to water it when its upper layer has dried up, but also little by little.

If the room has high humidity, for example, an anthurium is standing next to a huge aquarium, you need to water it even less often, the soil in the pot will remain wet for a long time.

Chlorine in water for irrigation

Do not water the anthurium with tap water. It is only possible with filtered liquid, which is suitable for drinking.

Do not pour water that was in the refrigerator, since the lowered temperature of the water can harm the root system of this delicate flower.

If it is not possible to pour filtered water, tap water must be drawn into a wide container, for example, in a bucket, and left open in the room for a day so that the excess chlorine disappears and the water itself becomes warm.

Too small pot

The problem is solved by transplanting into a suitable pot. In the new, 2-3 cm should remain from the walls to the root.

Excess fertilizer

In spring and summer, it is necessary to feed no more than once every 2-3 weeks with an azophos at a concentration of 1 g / l with the addition of potassium humate in an amount of 200-300 mg / l. Organic fertilizers are fed no more than once a month.

Lack of light

Anthurium does not like the scorching rays of the sun, but too far from the window in the shade its leaves begin to turn yellow. The best option - western and eastern windows or place on the table next to the south window.

Natural aging

If all the leaves are green and healthy, new young ones grow, the plant is provided with proper care, but one or several lower leaves are yellowed, they need to be cut off. This is a natural process, do not worry about this.
