The reasons for the yellowing of green mass and the main ways of dealing with it are described below.

Causes of yellowing leaves and how to fix the problem

Florists who have been deprived of experience often ask themselves why the leaves of indoor flowers turn yellow, what to do in this situation. The yellowing of the green mass of indoor flowers is not only not aesthetically pleasing, but also dangerous. A similar symptom may indicate the development of a disease or the impact of pests, which can cause the death of an ornamental culture. The main reasons that provoke the appearance of yellowness on the leaves are described below.

Dry air

The problem of dry air most often arises in the winter, when the heating system starts up in the apartments. Flower pots located near the battery may suffer from dry air. The microclimate in the room in this case adversely affects the growth and development of flowers. To cope with an unpleasant situation, it is necessary to use air humidifiers during the cold season. Also, the solution to the problem will be the systematic spraying of green mass of flowers. Containers filled with cold water are placed near the pots with plants.

Low air humidity

This problem often leads to the death of flowers. Low humidity is especially negative for tropical plants that require high humidity. For a solution, experienced florists recommend using a humidifier or placing pots with plants on moss / moistened expanded clay.

Lack of lighting

Every plant needs sunlight. Lack of lighting negatively affects the appearance of the decorative culture: growth slows down, and foliage begins to deform. It is very important, if a problem is detected, to transfer flowers in a timely manner to well-lit areas in the room.

But the lighting should be metered, because even with an overabundance of it, the flowers may suffer. The resulting sunburn provokes the yellowing of the green mass. It is important to place the pots in places where direct sunlight cannot enter. However, do not put containers in a dark corner of the apartment. If you still have nowhere to place indoor flowers, you can shade the plants a little with loosely covered blinds, which will help prevent direct sunlight from reaching the plants.

Lack of fertilizers and nutrients in the soil

To normalize the amount of fertilizer in the soil, you can:

• make the necessary dressing;
• start transplanting flowers into fertile soil.

When transplanting, the roots of flowers are thoroughly cleaned of an earthen coma.

• organize the correct watering regime;
• make in a timely manner and do not overdo it with top dressing;
• grow plants with strict adherence to the temperature regime in the room.

To cope with a fungal infection, it is recommended to treat home flowers with effective fungicides. Affected flowers are transferred to a separate room. The best fungicides to help fight fungal diseases are:

• trichodermin;
• agate;
• zineb;
• abit;
• phytosporin;
• gamair;
• bordeaux liquid.

Parasites

Often, flower growers devoid of experience are interested in why indoor flowers turn yellow. In cases where the plant is affected by pests, its appearance undergoes changes: the foliage turns yellow and withers, flowering may even stop altogether. Affected plants should be removed to another room as soon as possible. The foliage is wiped with soapy water, and the air humidity is increased by using a humidifier. Then you need to use the effective insecticides presented below.

If the flower is attacked by insects living in the ground, it is necessary to transplant it into pots that have been previously disinfected. It is very important to replace the soil in all containers.

Most often, yellowed foliage indicates the effect of the scale insect on the plant. Covering the insect's body with a shield complicates the fight against it. To clean the pest from the shields, you must use a toothbrush, abundantly moistened with a solution of alcohol.

For each m² of plantings, 200 ml of liquid will be required. The number of treatments should not exceed four times. The recommended break between treatments is four days;
• phosphatecide. It is advisable to take the flower pots outside during processing. For every 2 liters of water, 4 ml of the drug will be required;
• in cases where parasites attacked low flowers, it is best to use aktar solution to moisten the soil. This insecticidal agent is able to penetrate the plant through the root system and for a short period of time make any above-ground organ toxic to pests. After processing, it is important to thoroughly wash the window sills or shelves on which the flowers stood. Window panes also need to be thoroughly rinsed with clean water.

To prevent the appearance of scale insects on the foliage, it is worth abandoning the dense placement of containers with flowers, abundant watering and too shaded places.

Bacterial and viral infections

Any bacterial infection of the plant is accompanied by yellowing of the leaves. To be sure that it was a bacterial infection that caused such trouble, it is worth carefully examining the green mass of plants. An oily greasy spot on the back of the foliage indicates an ailment that affects ornamental culture. In addition, growths can be found on the stems and root system. Any of the chemical methods of struggle will be powerless in this case.

• vitaros (for every 3 liters of liquid, 6 ml of the product).

With the help of the prepared solution, it is necessary to spray the plants three times. A break of 9-10 days should be taken between each procedure.

Yellowing can be caused by infection

If strong yellow foliage is found, it is recommended to get rid of diseased plants. Indoor flowers are processed:

• 1% solution of Bordeaux liquid;
• oxydome;
• cuproxate;
• topaz;
• Quadris.

The latter is sold in cans and is intended for agricultural use. However, experienced florists have noted its effectiveness in the treatment of indoor plantings (flowers or trees).

How to care for flowers so that the leaves do not turn yellow

Any grower wants his plant to look good and be absolutely healthy. To prevent yellowing of leaves in indoor plants, you should adhere to the basic recommendations listed below regarding flower care.

• The absence of drafts in the room is a guarantee of the health of flowers. Indoor plant is not adapted to gusty wind and air movement. In cases where the green mass of plantings begins to turn yellow, and an air conditioner is located near the flower pot or a window is open, it is worth looking for a new place for the decorative culture.

To eliminate the problem, it is recommended to rearrange the pots in a warm room in which the temperature does not drop below 10 ° C.
• Cold surfaces. A similar situation occurs most often in the winter, when growers put containers on the windowsills. The ice window, touching the green mass of plants, contributes to hypothermia of the foliage.This causes yellowing of the tips of the leaves, their further death and decay. It is important to remove diseased leaves as soon as possible, and move the pot to another safer place.

• The lack of useful elements in the soil often causes yellowing of the foliage. It is very important to apply top dressing in a timely manner and observe the recommended break between fertilization.
