Yellow leaves on indoor plants. What to do and why the leaves of indoor plants turn yellow Why the leaves of indoor plants turn yellow

Plants? Every gardener has encountered this problem at least once: the pet's leaves suddenly begin to turn yellow, wither, and over time they dry out and fall off. In this situation, you need to deal with the causes of the pathology as soon as possible, otherwise the plant may die. Leaves can turn yellow both due to improper care and due to diseases and pests.

Improper care

The most common cause of yellowing leaves indoor plants- Not proper care. Once a plant finds itself in unsuitable conditions, it begins to lose leaves, which over time can lead to its death.

Let's take a closer look at the main reasons why a leaf can become yellow and lethargic:

Insufficient watering. If the earthen ball is overdried, the leaves first become limp and droop due to a decrease in turgor pressure in the plant cells, and then begin to turn yellow and dry out. Some indoor flowers very sensitive to drought - just miss it once, and the leaves will already begin to turn yellow.
Excessive watering. If the flower is watered too often, a similar effect will be observed, as the roots will begin to rot. The first sign of overwatering in many plants, for example, spathiphyllums, is dry leaf tips: they first turn yellow and then may turn black. Excessive watering is especially dangerous when the room temperature is low.
Indoor air is too dry. Many indoor flowers grow wild only in the tropical zone, where it is almost always hot and the air is humid. If you do not provide the plant with appropriate conditions, it will always feel bad.
Drafts or cold air from the air conditioner. This is another common cause of yellowing leaves. Plants should not be left near open window sashes, especially when ventilating the room in the cold season.
Insufficient lighting. In this case, the plant gets rid of leaves that do not receive sunlight; this problem especially often occurs in hibiscus. It is advisable for light-loving plants to find a place on the south or east side of the house.
The problem of yellowing leaves can also arise due to incorrectly selected. Iron chlorosis often occurs, a disease in which the leaf itself turns yellow, but the veins remain green and become clearly visible. This disease is caused by a lack of iron in the soil, and hydrangea and azalea often suffer from it.

It is for these reasons that leaves turn yellow most often. To restore a flower, it is necessary to provide it with comfortable conditions and eliminate the influence of all dangerous factors. It must be remembered that sometimes leaves turn yellow and fall off for natural reasons - over time, the leaf plate ages, and after falling it is replaced by a new one.

Diseases and pests

The most common diseases and pests of indoor plants:

Spider mite- a common cause of yellowing leaves. It is especially dangerous for roses and will be extremely difficult to get rid of. The disease first appears whitish coating on the leaves and the formation of barely noticeable cobwebs, then yellow spots appear on the leaves, and they begin to gradually die off. The mite can very quickly destroy the plant completely.
Aphids and scale insects They feed on cell sap: because of them, clearly visible brown plaques appear on the surface of the leaf. Pests live in large colonies, so comprehensive treatment is necessary.
A common cause of yellowing is fungal diseases. They appear as yellowish-brown spots on the leaves, the blades wither, dry out and fall off, and the fungus moves higher to the next leaf. This disease often affects geraniums. The fungus is well preserved in the soil, so not only medical treatment is necessary, but also soil replacement.

Due to these and other diseases, the plant can quickly lose leaves, which poses a serious threat to it. Measures should be taken as soon as the first symptoms of the disease are detected.

If the cause of yellowing leaves is improper care, then it is necessary to provide it with comfortable conditions in accordance with individual requirements and features. To prevent the soil from drying out, it is necessary to water according to a schedule with approximately the same amount of water at room temperature.

If the air in the room is too dry, the plant should be regularly sprayed with water - this will protect the leaves from drying out and they will not turn yellow. If there is a lack of light, illumination can be enhanced using special fluorescent or LED lamps: uniform illumination will ensure good growth and timely flowering.

If a plant loses leaves due to a lack of microelements, fertilizing with complex minerals is necessary. From March to October, the plant is fed in small doses once every 10 days, and in the cold season - once a month. This will correct the imbalance.

If the disease is caused by pests, it is necessary to isolate the plant from the rest as quickly as possible and carefully treat each leaf blade with a soap solution. It takes a long time to fight most pests; only repeated treatment helps, allowing you to kill all the insects. To treat fungal diseases, fungicides are used in doses recommended by the manufacturer.

Prevention Tips:

To prevent infection spider mite Excessive dryness of the air in the room cannot be prevented: the plant must be sprayed regularly. Many pests are afraid fresh air And sunlight: Do not allow leaves to become too thick.
To prevent the spread of pests, it is necessary to regularly inspect the plants: at the first sign, you need to remove the affected leaves, isolate the plant and carry out comprehensive treatment.
To prevent fungal diseases, plants need proper care. Excessive soil moisture should not be allowed; the air in the room should not stagnate. Healthy plants kept in comfortable conditions are able to resist fungus, so constant care for the health of the inhabitants of the window sill is necessary. It is important to fertilize on time, but not to allow excess fertilizer in the soil.

In any case, a yellowed leaf is a signal that the plant is not satisfied with any of the environmental conditions. It is necessary to identify and eliminate the dangerous factor as quickly as possible in order to prevent the green pet’s condition from worsening.

There are many plants living in homes and offices. Each variety and type indoor flowers has its fans. Some people love roses and ficus trees, while others like modest geraniums. When caring for home plantings, novice and experienced gardeners face various problems. Indoor plants, instead of delighting with lush greenery and abundant flowering, they begin to fade, get sick, their leaves become dull and dry. Why the leaves of indoor flowers turn yellow - what to do in this case is described in this article.

Causes of yellowing leaves and ways to solve the problem

When the leaves of indoor plants turn yellow, before doing anything, you need to figure out the reasons. Every problem has its solution. The situation with yellowed leaves is aggravated by the fact that there are many reasons leading to such a sad result. Most often they require a comprehensive solution.

Cyclamen is one of the most interesting indoor plants

It is possible to restore the lost color of green leaves only after identifying the cause of yellowing and getting rid of it. Risk factors for why indoor flowers turn yellow are divided into two large groups:

Violation of plant agrotechnics. These reasons are the most common. Especially for beginner gardeners. A change in the color of the leaf blade is the very first reaction of the plant to inappropriate care. Of course, each flower requires an individual approach. But since they are all contained in homes, solutions for different types often coincide.
Pests and diseases. They are dangerous because they can spread from one infected plant to others. Affected specimens must be urgently treated or, if the disease is incurable, destroyed.

Yellowed leaves

Below are discussed in detail various reasons yellowing of foliage and ways to eliminate them.

Dry air as a cause of yellowing

Dry air is a problem winter period. Dried by batteries central heating, it draws moisture from the leaves. Plants with thin, delicate leaves are the first to suffer. They turn yellow and dry out.

Attention! Maintenance optimal humidity- the key to good health and active flowering of indoor plants.

You can humidify the air with special household appliances and using devices made from scrap materials.

The problem can be solved by regular spraying, although this method is not suitable for plants with pubescent leaves, as well as begonias and some other species. A good option might be a container of water or wet expanded clay placed next to the pots.

Insufficient watering

Yellowing of the tips of the leaves is a sure sign that the plant needs moisture. Even with regular watering and a substrate that is damp to the touch, it may happen that the roots do not receive enough water.

Using untreated water for irrigation can also cause yellowed leaves. Tough, not settled tap water will cause yellowing and wilting of plants.

Watering is carried out until water begins to appear in the pan. If the soil is very dry, you can water the flower by immersing the pot 2/3 in water for a while, allowing the water to saturate the entire lump.

Lack of lighting

With a lack of light, the foliage of indoor flowers loses color unevenly, and often even falls off. This type of leaf fall is typical for hibiscus.

Attention! If the leaves turn yellow on only one side of the plant, this is a clear sign of lack of lighting.

Flowers will turn yellow if the pots are too far from the light source, or on window sills oriented north, northwest.

Particularly affected by lack of sunlight light-loving plants. Flaw natural light easily compensated by artificial ones. A lamp with a fluorescent lamp is suitable. Such lighting does not overheat the flower and consumes minimal energy.

Sometimes you can solve the problem by turning the yellowed part of the plant towards the light.

Excess lighting

Direct solar lighting no less harmful to plants.

Bright rays leave burns on the leaves. These yellow spots will be located on the illuminated side of the plant.

Shade-loving species require less light and have a greater risk of damage from excess lighting.

Lack of fertilizers and nutrients in the soil

The lack of nutrients in the soil affects the metabolic processes of the plant. A deficiency of a particular substance can be determined by specific signs:

Feeding is important for indoor plants

Nitrogen. A macronutrient, indoor flowers that grow for a long time in the same substrate suffer from its deficiency. The foliage becomes pale green or yellow, becomes smaller and withers.
Calcium deficiency is determined by a specific yellowing of the tips of leaf blades.
Magnesium. Its deficiency can be determined by small spots between the veins, which increase in size over time. If magnesium does not reach the plant at all, then the yellow color of the leaves turns into orange and red.
Copper deficiency is similar to magnesium deficiency, but the symptoms include leaf wilting.
A lack of manganese will result in leaves turning gray-yellow or yellow-green. This color will appear on the leaves of a plant planted in a substrate with a strong alkaline reaction.
Molybdenum. The edges and areas between the veins turn yellow, while the leaves and petals curl - a signal of molybdenum starvation.

The problem of lack of nutrients in the soil is solved quite simply. The application of complex fertilizers, preferably containing elements in chelated form, will restore the greenness of flowers. When feeding, it is worth taking into account the characteristics of the plant and the phases of its life cycle. During active growth, the flower needs nitrogen, and during the flowering period - potassium and phosphorus.

Important! It is worth considering that simply replanting a plant into better soil may be more beneficial for it than a series of fertilizing.

Excess fertilizer

Excessive feeding will lead to chemical burns of foliage and roots, which will ultimately cause the death of the plant.

Important! In most cases, it is better to “underfeed” than to overfeed.

Disadvantages of temperature conditions

Indoor plants, unlike garden plants, are not adapted to winds and drafts.

Drafts

If a plant standing under air conditioning or open window If the leaves turn yellow, then it is enough to change his place of residence.

Sudden temperature changes

Temperature changes, both downward and upward, can cause stress for the plant.

Cold surfaces

In cold winters, foliage in contact with window glass may turn yellow. In this case, there is a danger of the plant dying from hypothermia.

Yellow leaves need to be removed and the flower moved away from the glass.

Pot for indoor flower

An unsuitable pot can cause plant disease.

In an overly large pot, moisture stagnates and the roots rot.
In a very small one, the substrate dries out quickly, and root system does not develop, and there are few nutrients there.

A tree growing in a tiny pot is doomed to fall leaves even with the best care.

Important! You definitely need high-quality drainage from expanded clay and broken clay pots.

Errors in soil selection will affect the condition of the pet. The use of universal primer is unacceptable. Each species requires a special soil composition.

Infectious diseases

An infection that appears on one flower can quickly spread to neighbors, so diseases must be promptly recognized and treated. Infections that lead to yellowing of foliage and methods of treating them are reflected in the table.

Pest	Description	Signs of appearance	Risk group	Fighting methods
Spider mite	Peak activity is winter and early spring, when the indoor air is dry. Belongs to arachnids. Common types: ordinary, cyclamen, red.	The leaves become dull, lose color, begin to fade, and cobwebs appear on the lower surface.	Hibiscus, ficus, dracaena, ivy, tradescantia, fuchsia, citrus.	1. Warm shower. 2. Treatment with soap solution or garlic infusion. 3. For severe damage - acaricides, systemic insecticides
Aphid	Light green or yellowish insects, living in large colonies.	Unhealthy, curled leaves, damaged buds and growing points.	Plants with delicate foliage and shoots. Small-leaved species are especially vulnerable.	In the early stages, the plant is quarantined and treated with a strong soap solution. If there is a lot of pests, insecticides will help: Actellik, Aktara, Inta-vir and others.
Shchitovka	Insects from the scale insect family, the body is covered with a waxy shield, which makes it difficult to combat the pest. Found on inner surface leaf, in the vein area.	Yellow-brown spots along the leaf veins. Affected leaves lose color and wilt.	Ferns, asparagus, ivies, lemon, begonias.	Difficult to treat. Effective combination mechanical cleaning and treatment with Aktara. Females can only be destroyed mechanically.
Thrips	Sucking pests. The larval stage takes place inside the leaf; the flying adults are black and can quickly infect an entire collection of flowers.	The larval stage can be identified by light dots and streaks on the leaves. The leaf is deformed, its structure is disrupted, its color is lost, and it dies.	Palm trees, citrus fruits, hoya, monstera, laurel, syngonium, saintpaulia.	At the larval stage it is curable with systemic insecticides.
Root nematodes	The larvae live in the soil. Once in the roots, they develop there, forming growths that block the flow of water and mineral salts to the shoots.	Slow growth, yellow leaves, swelling on the roots.	Plants planted in contaminated soil are at risk.	1. Disinfection of roots with a fungicide. 2. Substrate replacement. 3. B difficult cases It is better to destroy the plant immediately

Note! Folk remedies, such as treatment with soap solution, infusions, and so on, only help with early stage pest damage.

Natural aging of plants

In an adult plant, sooner or later the aged leaves die off.

If there are no signs of diseases or pests, and agricultural practices have not been violated, you should not be afraid of such leaf fall. Some plants, such as cyclamen and hibiscus, shed individual leaves all year round.

How to care for flowers so that the leaves don't turn yellow

The rule that it is easier to prevent a disease than to treat it also applies to caring for indoor plants.

Plants on the window

The main methods for preventing yellowing of leaves of domestic flowers include:

Water the flowers only when the earthen ball is about half dry.
Regular replanting of plants, change of soil.
Carrying out fertilizing, while the dose is used slightly less than the instructions for the drug require.
Providing a long photoperiod, excluding direct solar radiation. In winter you can use a phytolamp.
Compliance temperature regime and the level of air humidity required for each type.
Choosing a pot according to the size and age of the plant and the condition of the root system.
Drainage is required.
Eliminate drafts and cold air flows.
Conducting weekly inspections of your collection of house plants, monitoring soil moisture, the appearance and condition of each flower, signs of pests and diseases.

Before ridding your pet of yellowing foliage, you need to evaluate life cycle plants. If this is not a natural course of events, then you can begin to implement rescue measures. Using the information provided, you need to find out the reasons for the wilting and then systematically restore your favorite flower.

Almost everyone has encountered the problem of yellowing leaves of their “green pet”. Often the foliage color of indoor plants changes in autumn or winter season. Before taking any action, it is necessary to establish the reason why the leaves of indoor plants are turning yellow.

Determine soil moisture

The most common cause of yellowing leaves of indoor flowers is improper watering.

First, a simple test: stick your finger into the soil to a depth of 2-3 cm. If you feel that the soil is dry, just water your flower.

It should be noted that reducing or increasing the frequency of watering is not always a sufficient measure. Selected species tropical plants adapt to life in room conditions according to your climatic habits. If you watered such flowers abundantly in the summer, then with the onset of winter they may begin a dormant period, and watering will need to be reduced, and in some cases, stopped altogether.

Excessive soil moisture often leads to rotting of the plant's root system. As a result, the leaves may also turn yellow. The flower may die if measures are not taken to restore it.

However, why do the leaves of the plant turn yellow if watering is carried out according to a schedule and all the required standards for its maintenance are met? In such a situation, the cause may be flooding the plants with cold or chlorinated water. hard water. Thus, experienced gardeners recommend letting the water sit for at least a day before watering.

Have a pest inspection

The abundance of sunlight is one of the most comfortable conditions for the existence and development of any flower.

Insufficient lighting can contribute to yellowing leaves in your pets. If you do not have the opportunity to move the pot to a brighter place, then try to provide lighting to the plant using phytolamps.

However, remember: excessive lighting is not always beneficial for plants, since yellowing spots are often the result sunburn leaves.

In this case, the flowers should be arranged, trying to avoid direct sunlight. It is not necessary to hide them in shaded corners for these purposes. The problem can usually be solved by keeping curtains loosely closed, which can protect your plants during the hottest parts of the day.

Remove the flower from the draft

Most indoor plants (especially those of tropical origin) do not tolerate drafts at all.

For this reason, if the leaves of indoor pets begin to turn yellow and dry out, it is worth moving them to a place where they will not be disturbed by the movement of air from open windows and the direct cool of a running air conditioner or fan.

This is exactly the kind of trouble that can nullify all the efforts and worries taken. So, even the healthiest, well-groomed plant, when exposed to a draft, signals with yellow spots on its leaves and asks you for help.

Be sure to feed

Fertilizer feeding can vary greatly depending on various types plants.

This may be reflected in the content of nutrients included in the formulation, dosage and frequency of application required. For example, the cause of yellowing of flower leaves will be both a deficiency of nutrients and their excess.

As a rule, it begins in the upper part of the plant and gradually appears in the form of yellowish spots on the plates along the veins.

When purchasing indoor plants, every gardener wants to get a beautiful, healthy flowering bush. In many cases, you have to deal with a fairly common problem - yellowing of leaves. In order to take measures to eliminate it, you need to find out why the leaves of your home flowers have turned yellow.

Plant aging

This is the most common cause of yellow leaves on flowers. For this reason it is enough easy removal old branches. You should also replant the flower and continue to care for it as before. If the plant is aging, it makes sense to grow a new bush of the same flower in a separate pot.

It’s worth turning your attention to the pots in which your crop grows. The walls must allow air to pass through (most suitable material- ceramics), fertilizing is applied to the soil in a timely manner. This way, the aging of the plant will be delayed for a while.

Improper watering

Many plants need moderate watering; when buying a plant or choosing it from a photo, inspect it for yellowed leaves, the condition of the soil in the pot, and the contents of the instructions.

Very heavy watering leads to the soil layer becoming waterlogged. This becomes a factor in the beginning of root rotting. As a result, yellowing of foliage and shoots occurs. Timely action can save the flower.

Just like overwatering, overdrying causes foliage to wilt and even dry out. Due to an insufficient amount of minerals and trace elements, the root system begins to die, consequently, the entire plant dies.

Presence of drafts

Most indoor plants do not tolerate cross ventilation, wind from an open window, air conditioner, or fan. Also, with rapid changes in air temperature, flowers may respond by yellowing the green mass. Acclimatization of the culture occurs in almost all plants with diseases.

Incorrect lighting mode

With a lack of sunlight, the leafy part of the plant begins to change color precisely in the part that experiences a greater lack of light. By looking closely at the flower, you can appearance to understand whether it has enough sun, or whether it needs to be illuminated artificially.

But being in the open sun is also detrimental to indoor crops. When exposed to direct sunlight, yellowish spots form on the leaves. In most cases these are burns. The plant must be urgently moved to a zone of diffused light.

Excessive or insufficient amount of fertilizing

With the occurrence of a lack of minerals in the soil layer, the foliage of the flower begins to acquire yellow along the midrib on the upper part of the plant.

When yellow spots appear in the interveinal space of the leaf, the reason lies in the lack of magnesium.

The appearance of spots and lethargy of the plant, loss of leaf elasticity - the plant does not have enough copper.

The overall color of the crop becomes a yellowish-gray shade—not enough manganese.

Curling and the appearance of yellow spots is a lack of molybdenum.

The yellow color is only on the tips of the leaves; the plants do not have enough calcium salts.

Having found out the reason why the leaves of flowers turn yellow, it is not difficult to solve it. Enough to feed them the right composition fertilizers

Plant disease and pest damage

You can understand what needs to be done if the leaves of flowers turn yellow only after a thorough inspection of the entire plant. In this case, it is possible to quickly take measures to treat the flower.

Carrying out preventive inspections of foliage and shoots will lead to the fact that there will be no need to look for ways to destroy pests, the plant will delight with its lush appearance.

When purchasing a new plant, you should familiarize yourself with the rules for caring for it. Proper watering, lighting regime, air humidity, soil composition - all this is fundamentally the basis for growing a plant with beautiful bright green foliage.

Photo of yellowing leaves of flowers

Houseplants are the same pets as everyone’s favorite hamsters, dogs, fish, turtles, and cats. They also require increased attention and care, but if a hungry puppy begins to whine pitifully and twirl at the owner’s feet, then the flower, deprived of water and nutrients, will simply wither.

Let's try to find out why the leaves of houseplants turn yellow and what needs to be done to restore a healthy appearance to your flower.

Causes of yellowing

Factors that cause yellowing of indoor plants are: great variety:

uncomfortable living conditions;
infectious diseases;
actions of pests.

In the vast majority of cases, the cause of severe yellowing of leaves is errors in care.

Light deficiency- in this case, the leaf plates do not become rich yellow, but rather simply turn pale. Simply moving your pet to a brighter place can help in this situation.
Effect of direct UV rays- plants require light, but diffused light. Direct radiation can be extremely dangerous for green tissues, as noticeable burns appear on the leaf blades. They look like blurry yellow spots on the surface, and they appear mainly from the side of the window.
Draft- most indoor plants react to the wind; cold air flows have the most unfavorable effect on them, causing stunting and yellowing.
Temperature fluctuations- temperature changes in the house are no less destructive for green pets. Try to protect your plants from them.
Interaction with cold surfaces- flowers usually face a similar problem in winter, when their leaves come into contact with frozen window panes. In this case, they turn yellow, and then gradually begin to rot and die completely.
Too bulky container- when the root system does not completely fill the container, moisture begins to stagnate where there are no roots. This provokes a sharp surge in the growth of fungus and mold, causing the appearance of various types of rot, which lead to the death of the roots. As a result, the above-ground part lacks water and nutrients, and the plant dries out.
Pot too small- the other extreme, no less dangerous for plants grown at home. If there is not enough land, then they will have nowhere to take useful microelements, so the pot should always be selected according to the size of the root system: no more, no less.
Poor drainage- in the absence of a drainage layer and holes in the container, moisture stagnation also appears, effective solution The problem will be transplanting the plant into another container.
Incorrectly selected soil- many beginning flower growers plant all house plants in the same substrate. This is the wrong approach, since all green pets have their own individual preferences. In addition, yellowing of leaf plates is often caused by too dense clay soils and soils poor in minerals.
The air is too dry- are especially affected by low humidity exotic plants, people from the tropics. To level out the situation, you need to purchase an air humidifier, place an indoor fountain near the flower, or fill a tray with moss, keeping it wet.
Sometimes the leaves turn yellow before the crop goes into dormancy, for example, cyclamen. This is a completely natural phenomenon - with the onset of spring, the flowers will again grow green mass.
Irrigation regime violation- both excessive watering and lack of moisture in the soil are equally destructive for indoor plants. In the first case, the roots rot, and in the second, they dry out. In any situation, they cease to cope with the flow of water and mineral elements into the ground parts.
If only the tips of the leaf blades dry out, then most likely you are irrigating them with hard, unsettled water straight from the tap.
And of course, lack of fertilizing also worsens the condition of the flower, although their excess often leads to a chemical burn, which can no longer be cured.

The cause of yellowing of sheets is often caused by fungal infection.

Fusarium- this disease occurs with constant waterlogging and leads to the gradual death of roots.
Late blight- the disease entails rapid withering of leaves, buds and young shoots.
Anthracnose- this pathology most often attacks indoor flowers with woody stems. In this case, the fungi quickly spread throughout the plant and cause yellowish spots to appear. Over time, they increase in size, merge and change color to brown.

How to deal with the problem?

To cure a diseased plant, it is first important to determine the source of the problem. If the reason is uncomfortable living conditions, you just need to change the care regimen for your green pet.

If there is a lack of light, you need to place the flower in a illuminated place; if the roots are rotting, you should remove all damaged fragments, replant your flower in a fresh substrate and adjust the watering regime, and if there is a deficiency of mineral nutrients, feed your green pet.

In order to get rid of the fungus, you need to move the plant as far as possible from other flowers and treat it with fungicides. Typically, about 3 applications are required at intervals of 7–10 days. It is best to cope with such pathologies with the compositions “Gamair”, “Agate”, “Abit”, “Trichodermin”, “Fitosporin”, as well as Bordeaux mixture.

Fungal diseases are quite common among indoor plants., most often with timely treatment they can be defeated. Less often, but green pets encounter pathologies of a viral nature - they cannot be treated. The only thing left for flower growers is to destroy the flower.

If the plant is affected by insect pests, then first of all you need to remove the pest itself. Usually, this is done by passing over the surface of the sheet plates with a sponge soaked in a solution. laundry soap or tobacco infusion. After this, the yellowed plant is sprayed with any systemic insecticide.

If the root system is damaged by insects, it is necessary to dig up the flower, clean it from the soil, wash the roots, soak it in a weak solution of potassium permanganate and replant it in another soil; it is best to also replace the pot.

The difficulty of dealing with any pests is that they multiply very quickly, and several colonies of insects are always present on each plant at the same time. In an adult state, it is quite difficult to destroy them, so several treatments are usually required, usually at least three.

Preventive measures

To prevent yellowing of leaves from causing death to your beloved green pet, he should provide suitable conditions content.

Water the plant only after the earthen ball has completely dried out, otherwise you will create a microenvironment favorable for fungal microorganisms. At the same time, we must not forget that most plants, especially exotic ones, react negatively even to a short-term lack of moisture.
Every two weeks it is necessary to give the plant fertilizer, but feeding should be dosed - it is always better to slightly underfeed the flower rather than overfeed it.
Provide your plants with bright but diffused lighting. Flowers have no place in the sun, especially in the hot summer. In winter, artificial lighting will be required; it is best to use a phytolamp for this. However, a regular fluorescent one will also work. Daylight hours should be at least 10–12 hours.
Protect your pet from drafts.
Regularly loosen the soil to provide the roots with oxygen.
Replant the plant in a timely manner into a nutrient substrate and a pot of suitable size.
Once a month, preventively spray the leaves of the flower with a solution of Fitosporin to prevent fungal infections.
Eliminate pests in a timely manner.
