An orchid disappears how to save the leaves turn yellow. Wrong watering orchids

Even such an unpretentious orchid in care, like phalaenopsis, can get sick at home. This flower is rarely exposed to fungal and bacterial diseases. In most cases, phalaenopsis leaves turn yellow and wither. This is the result of improper care. Why does this happen and what to do when the leaves of the phalaenopsis orchid turn yellow and wither? Explain the cause of the disease and offer them effective treatment only experienced flower growers. Their experience in dealing with orchid ailments is offered below.

Why do phalaenopsis leaves turn yellow and wither? Causes, treatment

If, upon closer inspection, no pests are found on the plant, but its leaves turn yellow and wither, experts point to improper care. Phalaenopsis suffers from it the most. So, why and what to do if the leaves of the Phalaenopsis orchid turn yellow and wither - explanations of experts with a photo.

Why do the leaves of the Phalaenopsis orchid wither:

  • frostbite;
  • periodic hit on the plant of cold air flows;
  • problems with the root system - improper transplantation, overdrying or waterlogging, root rot;
  • defeat by a fungal infection, which leads to blockage of the sap-bearing vessels of the leaf.

Why do phalaenopsis leaves turn yellow:

  • natural aging process of a flower. Norm, if 1 sheet turns yellow once a year. It is not normal if short span time turns yellow 2 or more leaf plates;
  • an excess of sunlight;
  • excess fertilizer;
  • various rot and diseases;
  • lack of moisture.

The signs of each ailment and how to eliminate them with a photo are given below.

Phalaenopsis wilted leaves talking about their frostbite. At the same time, the leaf plate loses turgor without any visible mechanical damage and painful spots. For an orchid, transportation without protection through cold air in winter or keeping near a window is fatal, where the air temperature often drops below + 15 degrees. Frostbite leaves lose elasticity, become dark green and watery. Treatment: the affected parts of the plant must be removed to healthy tissue. Dead tissues are a favorable environment for the propagation of a variety of rot. Make cuts with a sharp blade. Places of cuts are sprinkled with crushed, activated carbon.

In addition, you need to carefully examine the flower, whether there are black spots on its stem or other parts. A frozen plant is not transplanted. This is an additional injury that can lead to death.

In phalaenopsis, sluggish leaves may indicate an incorrect transplant, which resulted in a violation of the root system.. Many beginners are in a hurry to transplant the purchased plant, forgetting about its adaptation. Transplantation is additional stress. The plant can react to it with wilting of the leaves. If, after transplanting, the leaves of the flower fade, you need to do the following: remove it from the ground and carefully examine the roots. Next, the roots are immersed in water. Healthy roots, regardless of their original color (green, whitish) and condition (sluggish, shriveled), will definitely “get drunk” on water and become elastic. If the roots remain dry and shriveled even in water, they must be removed.

Trim the roots with a sharp blade to healthy tissue. In some cases, dead phalaenopsis roots are affected by rot. These may be black or gray spots. They don't have to be wet and slippery. Phanelopsis often suffers from dry, gray rot. If there are such spots on the roots, they must be removed. The stem affected by the fungus is also cut back to healthy tissue. In some cases, cut off completely Bottom part flower. Only leaves remain. It's not a problem. With the right further care, between healthy leaves, the plant will release roots.

After dead and diseased roots, sluggish leaves, and affected areas of the stem (if any) have been removed from the phalaenopsis, the phalaenopsis is placed in a greenhouse. In this case, the roots of the plant descend into a transparent vessel without water. The roots no longer need to be immersed in the liquid. The flower is covered with foil. This is how they make a greenhouse. She is supported inside high level humidity. The greenhouse is ventilated once a day for 15 minutes. Places of cuts on the stem are treated with activated charcoal. On day 2, the plant is sprinkled with dry cyclone. They are waiting for the appearance of new roots and carefully monitor the condition of the flower. Does it have black and gray spots rot.

As soon as phalaenopsis releases aerial roots, it is planted in a transparent vessel with a large bark. The resulting roots are sprinkled with bark. The layer should not be more than 2 cm thick.

What to do if the leaves of a healthy Phalaenopsis orchid wither? In this case, the transplant was not carried out. The plant is kept at a temperature within +18 ... +22 degrees, there are no cold air flows. Possible reasons: waterlogging of the substrate, which causes rotting of the root system. As a result, the plant can be affected by black rot. Signs of its appearance: black spots on the roots and base of the stem, sluggish leaves of the Phalaenopsis orchid. Black dots may appear on the leaves.

If the phalaenopsis is waterlogged, black spots appear on its trunk, in the following way: the plant is taken out of the pot, the roots are examined. Patients (who do not absorb moisture when immersed in water and with black dots) should be removed as described above. The leaves are also removed. The plant is placed in a greenhouse.

In extreme cases, waterlogging and, as a result, black rot, lead to rotting of the flower stem. If this happens, the orchid can no longer be saved. She is thrown away.

In phalaenopsis, the lower leaves turn intensely yellow, although the plant blooms profusely. Most of the roots are healthy and green, although there are aerial roots. They are wrinkled. Some of them had black spots and constrictions. Over time, the stem of the plant turns yellow. Possible disease flower: black, dry rot, which is caused by a fungus. Reason: waterlogging of the soil, lack of light. If the plant is intensively in color, this is not yet an indicator of its good health. Phalaenopsis throws out a peduncle after experienced stress, sometimes, in case of illness, as the last hope for reproduction.

Massive yellowing of the leaves of an orchid is not normal. This state of affairs should be alarming. In especially severe cases, the lower leaves turn yellow if the phalaenopsis infects the rot. It looks like dry black spots. There will be no wet spots on the stem and leaves that are characteristic of rots on other types of plants. Orchids do not get sick with wet rot. They are characterized by dry rot. It affects the tissues, prevents the movement of the juice, from which the leaves begin to turn yellow.

To verify the presence of the disease, the leaf is carefully cut with a sharp blade. It separates from the stem. Next, the stem is inspected. If there are black spots, it is black rot. In this case, the bottom of the plant is cut off to healthy tissue. To completely remove the disease from the flower, the cut is made to healthy tissue. How to know if the tissue is healthy or not? Very simple. The cut must be clean, without any inclusions. Very often, after surgery, the flower remains without roots. It's not scary. The main thing is that the growth point or upper kidney remains unaffected and green.

Next, the flower is placed in a greenhouse. It can be a transparent container or a cocoon constructed from polyethylene film. Inside the greenhouses maintain a high level of humidity. But the flower is by no means placed in water. Phalaenopsis rots from this. It is necessary to continue monitoring the flower. If black spots continue to appear on it, they are cut out with a sharp blade. The places of cuts are cauterized with brilliant green or sprinkled with crushed, activated charcoal. The greenhouse is ventilated once every 1-2 days. The plant is removed from the greenhouse when healthy roots appear on its stem between healthy leaves.

Why do the leaves of the phalaenopsis orchid turn yellow if there are no diseases and black dots on it, like clear sign dry, black rot?
Reason: not proper watering. In some cases, excess moisture accumulates in the soil as a result of its heterogeneity. So, phalaenopsis grows in a large bark of the same fraction. The presence of peat, moss, or even peat of different sizes in the bark leads to the fact that the mixture in the pot dries out unevenly. The next watering leads to waterlogging of peat. As a result, the roots or stem of the flower begin to rot.

The second case is when the plant is watered not by immersing the pot in water after the bark has completely dried for 15 minutes, but by top watering. Thus, inexperienced flower growers are trying to compensate for the dryness of the air in the room where the flower is located. Top watering is not suitable for phalaenopsis, dip method only. Otherwise, the stem begins to rot. As a result, the leaves of the Phalaenopsis orchid turn yellow.

To understand whether the leaves of the flower turn yellow due to rotting of the stem and roots, the plant is taken out of the pot, its roots are completely cleaned of the bark and inspected. A rotten stem will have a flabby appearance with possible mold (as shown in the photo). Even if such a stem has healthy-looking roots and the beginnings of new roots, they are still subject to complete removal. The stem is removed to healthy tissue. A healthy stem should be elastic and white on the cut without any inclusions.

After the cuts are treated with activated charcoal and dried. After that, the phalaenopsis with healthy leaves is either placed on the wet bark, while the bottom of the stem cannot be covered with bark, or placed in a transparent container with water so that the bottom of the stem does not touch the liquid. All this is covered with polyethylene to make a greenhouse. The plant is sprayed, the greenhouse is ventilated. You can process the bottom of the stem with dry zircon once a week. It is necessary to monitor the condition of the stem, if it continues to rot, cut it again. Healthy roots of the flower should appear between the leaves.

Once upon a time, an orchid could only be seen in the mountains or in dense thickets near lakes. Today, thanks to the breeders who "domesticated" this plant, it has become available to amateur flower growers. However, despite this, the orchid is very capricious plant and care must be appropriate.

The most common question that can be heard from flower growers is about orchids.

Let's see why this happens and what to do about it.

Reason #1

Have you been given or bought a new phalaenopsis or other orchid, have you brought the plant home, and after a while noticed that the leaves began to turn yellow sharply? In 95% of cases, this is the one that “clung” to the plant in the store. With a strong infection, the leaves suffer, and the orchids turn yellow and wither very quickly.

Without delay, start treatment, then there are chances of saving your pet.

You need to understand that if that disease is already deeper, and the whole plant needs to be treated. Here, removing one leaf will not save. The problem is that the fungus needs moisture. Therefore, in order to get rid of it, the orchid must be dried completely - both leaves and roots. Unfortunately, you won’t get by with one drying; in parallel, you need to treat the plant with antifungal drugs - fungicides. Otherwise, when you start watering the plant, the fungus will reappear.

Very often, in stores for a presentation, a flowerpot with an orchid is placed in a tight flowerpot. And, as a result, air does not enter the root system and moisture stagnates in the container, hence the fungus.

Reason two

The leaves of the orchid also turn yellow because they do not reach the leaves themselves useful material from the roots. In some cases, this is a natural process in which old leaves die off.

Each type of orchid has its own leaf lifespan. For example, the dendrobium sheds them every year, and sometimes twice. Phalaenopsis sheds the bottom old leaf once a year. The leaves of the calantha orchid die off when the plant is preparing for or during the dormant period.

Reason number three

A common reason for this is poor lighting. Plants with dense leaves need moist soil, but at the same time bright enough light. Perhaps in one year you will not understand that they do not have enough sun, they will behave normally, and in the 2-3rd year they may show signs of discontent. The way out of this situation is to specify their grade when buying. Very fond of the light of lellia and cattleya, as well as their hybrids. A great need for lighting in varieties of ascocenda, vanda, angrecums and rhynchostylists.

Reason #4

There is another option - the saddest one, from which no one is immune. And the problem appears unexpectedly, in the second or third year.

In order for orchids to quickly grow and bloom, sellers resort to tricks - they overfeed the plants with fertilizers. When buying, you see beautiful, luxury flower it may even bloom and delight you next year like a healthy orchid. The leaves turn yellow at the base suddenly and fall off in a couple of days. Fresh foliage in this case will not appear soon. Not all amateur gardeners have the patience to bring such a plant to life.

In order to avoid problems with plants, buy them in special nurseries, where you will have at least minimal insurance against such unpleasant surprises. If you are a beginner grower, choose varieties of orchids that do not require complex care. And then your plants will bloom and delight you for many years.

REFERENCE! In the leaves of plants there are such pigments: chlorophyll, carotenoids and xanthophylls, which are responsible for green, orange and yellow color, respectively.

The change of natural and artificial factors is reflected in the plant especially on leaves. As a result, chlorophyll ceases to be produced, and due to a small amount green pigment, in the light you can see the yellow color of the foliage.

What does it look like?

In orchids, not only the leaves turn yellow, but also the stem, peduncle. The tips may turn yellow, becoming pale yellow color, change the roots to a light color, the plant is covered brown spots, turns yellow and phalaenopsis. The appearance of a yellow color indicates ailments different kind or natural processes.

Often, and appear on the leaves and other parts of the phalaenopsis. You will learn about the reasons why this happens and how to save the plant from the articles on our portal. Read also about what these flowers are generally susceptible to, and methods for getting rid of them.

Phalaenopsis foliage turns yellow as a result of some factors:

Now you know why this is happening.

Harbingers

Upon contact with the leaves, roughness is felt - the first sign of the imminent appearance of yellowness.

IMPORTANT! This phenomenon indicates that the process of destruction of the sheet surface has begun. In this case, it is worth taking emergency measures to save the plant. And first you need to determine the reasons.

What to do?

Any grower can face the problem of yellowing leaves.. First of all, it is worth understanding the reasons for this phenomenon, and then looking for ways out of a difficult situation.

lack of light

They often happen because of the wrong lighting. Phalaeonopsis - shade plant, but this does not mean that he absolutely does not need sunlight. As a result of a lack of lighting, the leaves become smaller in size, the shoots reach for the light, becoming long, weak, and not formed. In the absence of light, the process of photosynthesis slows down.

Symptoms:

  • elongated shoots;
  • pale color of leaves;
  • fading look;
  • the flower is often subject to various.

How to help:

  1. move to a more lit place;
  2. if necessary, equip additional lighting.

Sunlight is of course good. But everything is good, should be in moderation. Phalaenopsis does not tolerate intense lighting. The direct rays of the sun on direct contact cause burns on the leaves. A plant that is not accustomed to bright light does not tolerate it well.

Concerning artificial lighting, there are also problems. Incorrectly selected, less than 20 cm, the distance between the lamp and the flower provokes thermal burns.

Symptoms:

  • yellow stem;
  • leaves that wither and fall off (for what other reasons do the leaves and flowers of phalaenopsis wither and how to save the plant, you will learn);
  • the appearance of dark, rough spots;
  • the base of the plant got a reddish tint;
  • yellow shapeless spots appeared on the leaves, places of burns.

How to help:

  1. remove the damaged sheet;
  2. transfer the plant to more comfortable place residence.

It often happens that after the purchase, the orchid blooms and actively develops during the first 1-2 years, and then the plant's condition deteriorates sharply, and the actions taken do not bring success. This is due to the overfeeding of the flower. Sellers often resort to such measures to obtain lush and bright flowering.

Symptoms:

  • burned roots;
  • yellow leaf tips;
  • slow development.

How to help:


Lack of nutrition also negatively affects the condition of the plant. With a lack of micro and macro elements, the leaves of the plant look like:

  1. magnesium deficiency- the leaves brighten, the veins remain dark;
  2. Fe deficiency- yellowness of the entire leaf;
  3. K deficiency- dry edges, the appearance of holes on the sheet;
  4. P deficit- old leaves dry up, part of the leaf dies;
  5. N deficiency The leaves dry up at the base.

ATTENTION! In order to restore a healthy Phalaenopsis appearance, feeds with the advantage of one or another nutrient should be added.

Moisture deficiency

Lack of fluid can occur with a complete lack of watering. The plant needs a minimum amount of water, which dissolves the nutrients in the soil and nourishes the root system.

Symptoms:

  • the tips of the leaves turn yellow;
  • the roots lighten;
  • the plant loses elasticity.

How to help:

  1. we extract the orchid from the flowerpot;
  2. immerse in a basin of water until the earthy coma becomes limp;
  3. pay attention, water should not get on the leaves;
  4. if necessary, place in a new pot.

A viral disease is a serious matter, but the good news is that such ailments are extremely rare. The reason for the defeat of the virus is temperature changes, flower transportation, a sharp change in humidity in the room.

Symptoms:


How to help: Treat the diseased plant with a broad-spectrum antibiotic or fungicide solution. However, such therapy may not give the expected result. Viral diseases are generally untreated.

The dominance of bacteria

Dangerous causes of phalaenopsis damage are bacterial infections. The disease occurs in some parts of the plant, while not affecting others. As a result, the disease is quite difficult to recognize.

Symptoms:

  • weeping spots;
  • yellow border on the leaves;
  • dark putrefactive formations on the green parts of the plant.

How to help:

  1. creation of optimally comfortable conditions for phalaenopsis;
  2. relocate a diseased plant away from healthy ones;
  3. delete damaged areas plants;
  4. spray orchid aqueous solution fungicide.

Fungi

REFERENCE! Fungal infection is considered a common ailment among phalaenopsis.

Small tubercles appear on the leaves, in which microspores of fungi are located. It is better not to touch these formations, otherwise you can infect nearby plants.

Symptoms: yellow tubercles on the leaves, neck of the flower.

How to help: treat the foliage with a fungicide solution or simply remove the diseased part of the orchid.


From time to time, the orchid sheds old leaves. There is nothing wrong with this process, on the contrary, it is considered the norm. A similar process is associated with life cycle phalaenopsis. The leaf plate begins to gradually turn yellow, becoming a bright yellow color, after which it wrinkles, darkens and dries out. The lower leaves turn yellow first. Natural dying occurs after 1-5 years.

Now you know what the treatment of the disease will depend on and what to do with it in each of the cases.

Prevention

It is possible to avoid such situations with proper care of the orchid.:

  1. Maintenance comfortable temperature in summer: +22-25ºС, in winter +16-18ºС. The difference in temperature differences should not exceed 5ºС.
  2. Lighting is required diffused, with a daylight hours of 14 hours. In the summer, intense sunlight needs to be shaded.
  3. Humidity within 50-60%. Be sure to regularly ventilate the room.
  4. Water once a week, allowing the soil to dry out completely.
  5. Orchids need to be fertilized 2 times a month, especially during the flowering period. Top dressing should be used with a predominant content of potassium and iron.
  6. It is better to spray phalaenopsis up to 5 times a day. Exclude the procedure during the flowering period.

Do not sound the alarm when yellow leaves at the phalaenopsis. Perhaps the cause is the old age of the plant, and the shedding of leaves is a rejuvenation process. However, it is better to be on the lookout. Carefully inspect the flower every week so as not to miss important symptoms, and recognize the cause in time. Now you know what to do if the phalaenopsis leaves turn yellow.

The phalaenopsis orchid has won many fans among flower growers, despite its capricious disposition. You need to take care of this plant carefully, otherwise it will show its character by shedding foliage. What to do if the phalaenopsis orchid leaves turn yellow and why this is happening will be discussed right now.

Phalaenopsis orchid leaves turn yellow, causes

There are several reasons why exotic leaf plates become yellow tint. It is important to note that with a certain frequency, the lower leaves of the Phalaenopsis orchid turn yellow and crumble. This is absolutely normal. This happens about once a year. At the same time, the upper leaf plates remain fresh and green. If you observe a different picture, that is, the upper foliage also suffers, then something is wrong with the flower. Probably some serious mistakes were made in the care. Consider them:

Insufficient watering. If the soil in the pot is constantly dry, the flower lacks moisture. In this case, he will not be able to remain luxurious and beautiful, the leaves will turn yellow, and then fall off.
Abundant watering. Phalaenopsis orchid also reacts negatively to too frequent and abundant irrigation. In this situation, there is a risk of rotting of the root system. exotic flower should be watered as the surface of the soil dries out.
Tight pot. If a close container is chosen for growing a flower, as the root system develops, it may be damaged. In this case, the exotic may die altogether.
Lack of light. In poor lighting, orchids suffer. First of all, they spoil appearance. The leaves turn yellow and may begin to crumble soon. Experienced flower growers cope with this problem with the help of special lamps.
Direct sunlight. Growing exotic plant, it should be remembered that it does not tolerate high temperatures and falling on the leaf plates of direct sunlight. Under such conditions, the plant will not last long.
temperature fluctuations. Phalaenopsis orchid does not tolerate sudden temperature fluctuations. She also does not tolerate being disturbed, especially in the period before flowering. The flower can react to any unpleasant manipulations by yellowing the leaf plates.
Overfeeding. Exot, of course, needs top dressing. However, an excess of minerals in the soil should not be allowed. It is recommended to introduce top dressing twice a month, using fertilizers designed specifically for orchids. Over time, salts accumulate in the soil, they need to be washed out periodically. For this, the soil is shed large quantity water and then let it drain.
Lack of fertilizer. If the plant is not fed at all, it will not be able to live. If the soil lacks nutrients, the flower will turn yellow, and then die.
Diseases or pests. Infection of a plant with fungal or bacterial diseases may be accompanied by changes in the appearance of the leaves. Yellow or brownish spots often appear on them, the edges of the leaf plates may turn yellow. A similar thing happens when a crop is damaged by some pests.

What to do - instructions for saving the Phalaenopsis orchid

Noticing that the leaves of the phalaenopsis orchid are turning yellow, try to analyze where the mistake was made in caring for it. First of all, it is required to increase the degree of illumination. Equip the corner where the pot stands with a fluorescent lamp.

In summer, plants standing on the windowsill should be shaded a little from the rays of the sun. Organize proper watering. AT hot weather The soil dries out faster, which means you need to water the flower more often. If it's cool, watering should be less frequent. Just control the condition of the soil in the pot.

Do not overfeed the plant. It is enough to fertilize it every two weeks. Every one and a half months, the soil should be washed with water to remove accumulated salts. To do this, the pot is placed on a wire rack and water is gradually poured into it. room temperature.

The volume of liquid should be three times the volume of soil in which the flower grows.
As the orchid grows, it must be transplanted, although it has a negative attitude towards any manipulation. Choose a spacious low pot so that the root system is freely located there. Remember that orchids need the right temperature regime. At night, the air temperature should drop by about 5-7 degrees relative to the daytime.

If the growing conditions fully comply with the listed requirements, you should make sure that the flower is not infected with pests or dangerous diseases. Some diseases, such as fusarium, are useless to treat. In other cases, it is worth fighting for the plant. If you arrange for your orchid right conditions, it will certainly recover, the leaves will grow back. However, sometimes this process is quite lengthy. Full recovery may take several months.

The reasons why Phalaenopsis orchids turn yellow leaves are numerous. It can be difficult to immediately identify the problem, so we recommend flower growers to work out all aspects of care. Perhaps by changing the conditions of detention, it will be possible to save the flower.

Phalaenopsis is considered the most unpretentious orchid, however, with room content it is not always possible to create comfortable conditions for its cultivation, and this leads to disease of the plant. The first sign that indicates that something is wrong with the orchid is the yellowing of the leaves. This phenomenon can have a variety of reasons, but all of them, as a rule, are associated with improper care. This article will help you understand why the leaves of the Phalaenopsis orchid turn yellow, and how to avoid it.

One of the most common reasons why the leaves turn yellow on home phalaenopsis is a violation of the irrigation regime. From excess moisture in the soil, the roots of the plant can rot, due to which the leaf plates begin to lose turgor and turn yellow. Also, the cause of yellowness can be insufficient watering. If the root system looks completely healthy, but the lower leaves turn yellow, this is a sign that the substrate has been overdried for a long time.

It happens that the orchid is watered correctly, but the leaves continue to turn yellow. In this case, you should pay attention to the method of watering. If it is carried out with the help of a watering can, then perhaps the water immediately enters the pan, not having time to moisten the substrate.

Another commonplace reason why phalaenopsis leaves turn yellow may be hard water. If the plant is constantly watered with tap water, albeit settled water, then this will lead to salinization of the substrate, and, as a result, to the cessation of iron absorption. If you water an orchid with such water long time, she will develop chlorosis - the leaf plates will become covered with light spots, and then turn yellow and fall off.

Lighting

The second, and no less global cause of yellowing leaves is improper lighting. Many flower growers believe that this tropical flower must certainly stand on the window so that as much sun as possible falls on it. And this is a big mistake. In nature, phalaenopsis lives next to big trees, which serve as a support for him and protection from direct sunlight.

At home, it is necessary to create approximately the same conditions - the light should be bright, but diffused. The best option to accommodate the orchid is a window sill in the southwestern part of the house. You can not put the pot on the windowsill on the south or north side. In the first case, the plant will receive burns, as evidenced by yellow spots on the sheet plates, and in the second - the leaves will turn yellow slowly.

Lack and excess of fertilizer

Illiterate selection and use of fertilizers can also lead to the fact that the leaves of the phalaenopsis turn yellow. Usually in the store we see healthy and beautiful orchids, completely unaware that they have been fed growth stimulants for a long time. A caring seller, of course, will recommend that you use these drugs at home, and be prepared for the fact that in a year or two the flower will begin to lose its original view- the leaves will begin to turn yellow sharply.

The explanation for this is simple - the plant is completely exhausted by stimulant drugs. Too frequent feeding contributes to the accumulation of nitrogen in the substrate, and its excess is just as harmful as its deficiency. Very often, the orchid turns yellow due to an excess of calcium or a lack of potassium. There is very little of this component in the plant, and if top dressing does not cover the need for potassium, then the flower will take it from the leaves.

Diseases and pests

If the leaves of the Phalaenopsis orchid turn yellow, despite the observance of all conditions of detention, then most likely it is sick or affected by pests. Yellowing of the integument can be caused by fungal and bacterial diseases arising against the background of waterlogging of the substrate or high humidity air:

Fusarium rot. The reason for its appearance is high humidity and lack of air circulation in the room. The main signs of the disease - the leaves turn yellow, become soft, the main shoot rots and dies.

Bacterial spotting. An infectious disease caused by tissue damage. The main symptom is wet ulcers on a yellowed leaf, which eventually becomes soft and dies.

Other reasons

In an adult orchid, the leaves may turn yellow for a number of other reasons. You should know that for home phalaenopsis it is considered normal to lose 1-2 old bottom sheets during the year - this is a natural physiological process. The orchid begins to shed leaves from old age at the age of 4–5 years. If the leaf turned yellow, turned bright yellow, then wrinkled, withered and fell off - this is a sign of its natural aging.

Also, the cause of yellowing may be too small a vase or pot in which the orchid grows. root system the plant grows very actively, and if it is not replanted every 2-3 years, the roots will be deformed, which will lead to malnutrition and yellowing of the flower.

Do not forget that the orchid is a tropical plant, accustomed to a constant temperature, and at the slightest draft or hypothermia, it experiences stress. And any stressful situation immediately affects the state of not only leaves, but also buds, inflorescences.

What to do

Of course, the phalaenopsis orchid, in which the leaves turn yellow, looks unattractive and needs help. What if this happened to your favorite flower? Above, we examined why the leaves of the phalaenopsis orchid turn yellow, and what to do depends on the cause of the lesion:

  • to avoid excessive wetting or drying of the substrate, better method immersion, then the plant will take as much water as it needs;

  • if hard water became the cause of yellowing of the leaves, then the orchid is transplanted into a fresh one, and settled water mixed with distilled water 1: 1 is used for irrigation;
  • when the orchid is affected by diseases, the leaves are washed soapy water and treated with fungicides: "Aktellik", "Fundazol", "Fitolavin";
  • if damaged by a root mite, it is necessary to remove the plant to transplant it into a new substrate, removing the damaged roots - in case of severe damage, insecticides are used: Agrovertin, Karbofos.

To keep your orchid always healthy, take the time to prevent. Periodically change the location of the plant, in winter time additionally highlight, and in the summer - shade from the sun. Follow the feeding scheme and replant the flower on time, and then it will regularly delight you with its flowering.
