The orchid's trunk has turned yellow, what should I do? Why does an orchid's trunk turn yellow?

House orchids differ significantly from their tropical ancestors, but are still considered one of the most demanding flowers. Many different conditions must be met to provide them with the necessary care and grow beautiful flowering plants. And in the process, many difficulties and problems can arise, one of which is yellowing of the leaves or stems of the orchid.

To understand why orchid leaves turn yellow and what to do so that this process stops and the plant is healthy and beautiful, it is important to understand the needs of the flower and comply with the conditions of its maintenance. Beginner flower growers are better off choosing less demanding varieties so that caring for them is easier and the result does not disappoint.

The main causes of yellowing orchid leaves

The reasons why the leaves of a domestic tropical plant may turn yellow are divided into natural and unnatural. A natural prerequisite, which is considered normal and should not cause concern to the grower, is the process of growth of new leaves and the death of old leaves. And although an orchid is a flower that is not characterized by active and intensive growth, new leaves will still appear, they will be larger in size than the previous ones. And then some of the old lower leaves should turn yellow and fall off.

An important condition for the normal growth of phalaenopsis with rare yellowing of the lower leaves is the growth of new ones, the healthy and beautiful state of existing leaves, as well as the regular flowering of the orchid. If several leaves begin to turn yellow, they look limp and soft, obviously the cause of this problem is different.

The most common causes of yellow leaves are:

Excess moisture. Excessive amounts of water are more destructive for an orchid than drought. Even if the top roots and pieces of bark look dried out, this does not mean that it is time to water the plant. For this purpose, the orchid is often planted in a transparent pot - in order to see the condition of the entire root system. You need to water the flower when most of the roots have turned light green.

Lack of moisture. No matter how much an orchid loves tropical drought, the plant still needs to be watered from time to time. A complete lack of moisture will cause the leaves to turn yellow quickly, one after another.

Sunburn. Partial yellowing of the leaf in the form of a spot or half a leaf may be the result of sunburn. This happens if the orchid is on the south side in direct sun. No house plant likes this location.

Insufficient lighting. The north side without additional lighting is detrimental for the plant, because the orchid is a tropical flower, accustomed to abundant sunlight.

Improper use of fertilizers. It is important not only to choose the right fertilizer for your orchid, but also to apply it in the required quantities.

Thus, there can be quite a few reasons for yellowing leaves, but most often they all depend on incorrect actions or lack thereof on the part of the grower.

Whatever the reasons for the yellowing of orchid leaves, having noticed the first signs, it is important to immediately take action and help the plant. Ignoring the wilting of a flower can lead to its complete death. And in order to understand what needs to be done and how to help phalaenopsis, it is important to know its requirements for care conditions and follow these rules.

What to do if the leaves start to turn yellow

Having noticed unnatural yellowing of leaves in large quantities or often replacing one another, it is important to carefully consider all the conditions that could provoke this problem. A responsible amateur gardener does not take thoughtless actions when monitoring changes in plant care. Therefore, identifying the cause of yellowed leaves will not be difficult.

To stop the yellowing process and return the orchid to a healthy and beautiful appearance, you need to eliminate the factor that provokes the problem. If the pot was placed in a new place that did not suit the phalaenopsis, you need to return it to its original place. If the watering regime is violated, return to proper moisture.

In some cases, a complete replantation of the orchid, replacement of the soil and removal of unhealthy roots is required. This must be done carefully, trying not to damage the good roots. You can take the same pot in which the flower grew before, and completely replace the soil with a new substrate. A few top roots can be left without covering them with pieces of bark. Knowing the conditions and needs of the orchid, it is important to try to comply with all of them and help the plant be healthy. Preventing yellowing of leaves and trunk is much easier than correcting the situation.

Why does the stem turn yellow and what to do?

Yellowing of the stem, or more correctly called its peduncle, after the orchid blooms is a normal process of plant growth. Especially if the phalaenopsis bloomed for a long time, delighting with new and new flowers on its stem. At the end of this stage, a dormant period begins, and the peduncle most often turns yellow and dries out. In this case, you need to wait until it dries completely to the ground, then trim it, and when the orchid is ready for new flowering, it will produce a young stem.

If the peduncle begins to dry out during flowering, and the flowers disappear and fall off, it means that something has changed in the conditions of caring for the orchid. Most often this is caused by a lack of light, including for the root system. If the pot has not been moved to a new place, you need to think about what other changes have occurred.

How to prevent yellowing of leaves and stems

When purchasing an orchid, every gardener needs to find out as much information as possible about the plant so that it is healthy, happy with its regular color, and to prevent yellowing of the leaves and stem. And although phalaenopsis is considered a demanding and whimsical house flower, there are also conditions for it under which it grows healthy and beautiful.

Proper care of an orchid

From the first days of an orchid’s life in an apartment, it is important to establish proper and regular watering of the flower. In winter, it is enough to moisten the plant once every 8-10 days, in summer - no more than once a week. You only need to water the flower through the tray, without pouring water into the pot from above.

To understand that phalaenopsis needs watering, you need to pay attention to the lower roots in the pot. When they become light green in color, which is approaching a white shade, then the plant requires moisture.

Air humidity and room temperature

It is important to monitor the humidity level in the room where the orchid is growing. For many flowers, this is a more significant factor than watering. The optimal humidity for phalaenopsis is 45-60%, so in winter, when the heating is running, you need to regularly spray the plant with clean water.

As for air temperature, the orchid can grow at 18 degrees, but also feels great at 26 degrees. However, the optimal temperature for flowering is 18-20 degrees.

Lighting and flower placement

The third factor in the healthy and proper growth of an orchid is lighting. Direct sunlight, as well as the shady northern side, are equally destructive for the tropical beauty. The best place for an orchid will be the windowsill of an eastern window or a counter near it. The morning rays of the sun will not harm the leaves of the flower, but this light will be enough.

Orchid replanting and fertilization

Phalaenopsis is a plant that does not like replanting and practically does not need it. The only situation when it is necessary to replant an orchid is active growth and small pot sizes. This can be understood by the number of roots that have begun to grow outside the pot: the more there are, the sooner a new one will be needed - larger. It is important to transplant the plant into the same transparent plastic container, replacing the substrate.

As for feeding the orchid, this can be done once a year, in early spring, to stimulate the exit from the dormant stage and the active growth of the flower. It is important to purchase special fertilizers; a universal product is not suitable for phalaenopsis.

Thus, yellowing of the leaves and peduncle of an orchid is most often a normal physiological process of plant growth, but in some cases it should cause concern to the gardener. Having noticed the first signs, you need to immediately respond to the symptoms and provide the orchid with the necessary conditions for comfortable growth.

It is important to know the rules and requirements for growing phalaenopsis so that they grow healthy and beautiful. The orchid is a whimsical flower, but if desired, the conditions for caring for it can be easily observed. Then it will grow, bloom and delight with its appearance.

Orchid leaves turn yellow

Why do orchid leaves turn yellow and fall off?

What to do with an orchid if leaves turn yellow and fall off, the tips of the leaves dry out, spots appear, the orchid turns yellow and withers. Orchid leaves differ from each other; more precisely, each species has its own shape, texture, color, and of course, life period.

The cause of any stressful condition is a sudden change in living conditions, improper care, insufficient lighting, too dry air, excessive watering, damage to the root system, and pest damage.

Yellowing can be caused by natural aging of the leaf and is not a cause for panic. Normally, the leaf turns yellow and dries out gradually over several months, and this process should not affect the remaining leaves. But rapid yellowing and falling of leaves occurs in deciduous species, which shed them during the dormant period (like some dendrobiums).

As a rule, orchid leaves have their own life cycle, in some species it lasts up to 5 years, in others - 2-3 years, in others - only one year. Many species completely or partially shed leaves on old pseudobulbs every 1-2 years. For monopodial orchids, such as Phalaenopsis, it is natural for 1-2 of the lowest (oldest) leaves to die. Many sympodial species (Dendrobium) can shed their leaves every year or every two years, before, during and after flowering.

The leaves of Dendrobium nobile orchids live relatively short, usually 6-18 months, in some varieties they turn yellow and die off neatly during the dormant period, there is nothing wrong with this, this is normal plant behavior.

Calanthe, for example, sheds its leaves shortly before or during its rest. Later, during a new phase of development, these plants quickly produce large amounts of new foliage. Tropicanas usually retain their foliage for many years.

Often the cause of yellowing leaves can be insufficient lighting.

Most plants prefer a place with sufficient humidity and bright light. Sometimes an orchid can germinate in low light conditions for 1-2 years, and only then begin to wither and shed its leaves.

Typically, orchids with hard and dense leaves are light-loving. These are almost all cattleyas, laelias and hybrids based on these species. Also included in the light-loving group are orchids such as Vanda, Ascocenda, Ascocentrum, Rhynchostylis, Angrecum, which have leathery leaves.

Orchids with soft, light green leaves easily turn yellow or burn in bright sun, so they need more shade. A good example is Miltoniopsis. Terrestrial shade-tolerant species that prefer partial shade include: lady's shoes and paphiopedilums, which most often have a mottled pattern on their leaves.

Yellowing of leaves is often accompanied by the appearance of roughness. The reason for this behavior is that the orchid is exposed to too much sun for a long time, causing its leaves to become very hot and their tissues begin to deteriorate.

Another option is to water generously with long breaks.

The orchid withers, despite regular watering, as a result of which the orchid leaves turn yellow and die. It is likely that you have overwatered your orchid! Or the pot is too small, the root system is compressed. It is necessary to adjust the watering - do not overdry or over-moisten the substrate. The bottom of the pot should not stand in water, otherwise the roots will begin to rot.

It should also be taken into account that in winter, hot air from radiators dries out the roots; it also noticeably reduces the humidity of the air around the plant. You can combat this by placing containers of water nearby or using a humidifier. And also move the orchids away from heating devices.

Overdose of fertilizers and stimulants

For rapid growth (especially during mass breeding of Phalaenopsis), the plant was previously overfed with stimulants and fertilizers. When purchased, the plant may look normal and bloom beautifully for the next 1-2 years, but then depletion sets in - three or more leaves turn yellow and fall off overnight, and new ones do not appear for quite a long time. Transplanting into a new substrate does not change the situation. Despite this, the plant can still be brought back to normal, but this will require a lot of time and patience.

The orchid must be placed in a warm, bright place. At first, you should hold off on fertilizing, then fertilize once every 2 weeks (dilute more with water). The first time, a regular fertilizer for orchids is used in half the concentration, then nitrogen is used, which promotes the growth of leaf cover. If before the formation of the first 2 leaves, the orchid decides to bloom, then the flowering of a plant that has not yet matured may be the last. Sometimes it happens that 2-3 years pass before the plant begins to grow foliage. As soon as the leaf cover returns to normal, you can again enjoy its flowering.

It should also be taken into account that the root system of many species is very sensitive to the effects of various kinds of potassium, phosphorus and other salts contained in the fertilizer and if too high a concentration is used, it can cause great harm to the plant.

In case of an overdose of fertilizer, you need to place the pot with the orchid under running warm water and pour it thoroughly. If necessary, the next fertilizing will need to be done no earlier than in a month and a half, and the fertilizer itself needs to be diluted more with water. Some species react extremely negatively to watering with too hard water, so when working with fertilizer it is best to use filtered water (as well as for irrigation).

Why does an orchid’s stem turn yellow and what to do in this situation?

We all love it when a beautiful indoor plant pleases the eye on the windowsill of an apartment. But some of them sometimes get sick. For example, Orchids are plants that require a lot of effort and care during the growing process. And when a flower’s leaves, peduncle or stem turn yellow, this causes concern in the owner. But there is no need to worry, but you need to understand the reasons; perhaps this process is the natural aging of the flower. In this article we will look at the causes of yellow leaves and possible ways to eliminate it.

What is yellowing?

It happens that orchids turn yellow. This occurs due to various factors affecting the life processes of the plant. As a result, the pigments responsible for the green color are formed in small quantities, and part of the flower changes color. Yellowing affects not only the stem, but the roots, leaves, and peduncle.

Yellowness can appear in one part of the plant, and subsequently affect all organs of the plant.

Consequences for the plant

It’s bad if the stem turns yellow on a young plant, then the cause of aging disappears by itself. The main danger is not to delay treatment, and at the same hour react to the first symptoms. Provide timely assistance to a diseased plant, as the consequences are fraught with:

complete yellowness and falling off of all leaves;

drying out of the peduncle;

deterioration of general condition due to infectious diseases;

disturbance in the development of the root system;

cessation of flowering.

Why does the trunk turn yellow?

Indoor orchids are somewhat capricious plants. They can react negatively to even minor changes in parameters during cultivation. This is reflected in the appearance of the beauties. Therefore, determining the cause of yellow leaves or stems is not always easy, but it is still important. The main factors of yellowness:

Sunburn. Bright light is, of course, good. But everything is fine, it should be in moderation. Direct rays of the sun upon direct contact cause burns on leaves, stems, and flowers. A plant that is not accustomed to intense light does not tolerate it well. Problems also arise with artificial lighting.

Incorrectly selected equipment can cause thermal damage. For these purposes, it is better to use phyto lamps that do not harm the plant and do not dry out the air. However, keep the distance between the lamp and the flower at least 20 cm.

Mechanical damage. A yellow color on the trunk may appear as a result of a fall or injury to part of the plant. The damaged part was not treated with an antiseptic in time, and as a result, wounds appeared on the stem, with possible rotting.

Lack of moisture. A lack of fluid can occur in the complete absence of watering. The plant vitally needs a minimum volume of water, which dissolves the nutrients in the soil and nourishes the root system. Symptoms of this cause are:

yellow leaf tips;

yellow stem;

light roots;

the plant loses its elasticity.

Lack of light. Orchids are shade-tolerant plants, but they certainly need sunlight. This is especially acute during the period of flowering and growth. When a flower needs 14 hours of daylight.

As a result of lack of lighting, leaves, aerial roots, and completely unformed buds dry out. In the absence of light, the process of photosynthesis slows down.

Excess moisture. Due to non-compliance with the correct watering regime, many ailments arise. In plants that are at rest, vital processes are suspended; they do not need fertilizing with mineral fertilizers or frequent watering.

At this moment, the flower does not absorb the same amount of moisture as, for example, in the growth phase, so the excess accumulates and causes yellowing, rotting, and wilting.

Fungal and bacterial infections. Violation of indoor microclimate parameters leads to the development of infectious diseases. This is also possible if the quarantine regime is not observed.

When is this process natural?

From time to time the orchid sheds its old leaves. There is nothing terrible in this process; on the contrary, it is considered the norm. A similar process is associated with the life cycle of a plant. In addition to the leaves, other parts of the plant also age: peduncle, trunk, roots, it’s just less noticeable. Natural death occurs after 1-5 years.

Changing the color of the growing point

The top leaf of monopodial orchids is called the growing point. Its yellow color means a deviation from the norm; the plant has health problems. The reason for this phenomenon is uncomfortable conditions for keeping exotic plants and improper watering. Also a consequence of damage to the flower by infection. If this leaf is severely wounded, the orchid stops growing upward.

Many people believe that without a growing point, a plant cannot survive. It can, but the probability is not 100%. Finding itself without an active core, the exotic is susceptible to fungal diseases. If he has enough strength to overcome ailments, the plant will survive. The flower can produce a lateral shoot on the stem or peduncle, thus continuing to grow.

What to do to save the plant?

If the unexpected happened, the orchid trunk began to turn yellow, its natural state changed, and definitely some problems arose. No need to wait, respond urgently:

Conduct a thorough visual inspection of the diseased plant.

Find out what is causing this condition.

Change the orchid's living parameters.

Control the quality and frequency of watering. Water should not remain in the leaf axils.

If the measures described above did not produce any changes, we proceed to more radical ones:

1. 
   Prepare pruning tools and disinfect them.
2. Remove any damaged tissue.
3. Treat the cuts with ground cinnamon or crushed activated carbon.

If the leaves fall in addition to the yellow stem, perhaps this process is another symptom of rot or an infectious disease. In such cases it is necessary:

1. treat the soil and plant with a 0.2% solution of Fundazol or Topsin;
2. pour the drug directly into the wound of the plant;
3. We carry out the procedure at least three times with an interval of 14 days;
4. regularly inspect the diseased flower for signs of rotting;
5. the buds on the peduncle can be treated with cytokinin hormonal paste to stimulate the appearance of children.

Prevention

During the first time after amputation, be sure to adhere to the following recommendations.

6. The first thing is to remove it from the southern window sill or shade the light with a tulle curtain. In autumn and winter, provide artificial lighting. The duration of daylight hours should be 10-12 hours.
7. Three times - maintaining a comfortable temperature in summer: +22-25? C. Do not place under air conditioning or leave in a draft; the plant may become overcooled. In winter +16-18?C. Do not place near heating radiators.
8. Third, the difference in temperature differences should not exceed 5? C. At temperatures above +25°C and high humidity, fungal infections develop, and at temperatures below +15?C – bacterial infections.
9. Use a household humidifier to maintain humidity within 50-60%.
10. Provide regular ventilation.
11. Moisten the flower once every 7-10 days; in between, the soil should dry completely.
12. Carefully ensure that moisture does not remain on the leaves. After watering, remove stagnant water from the leaf axils.
13. Avoid the use of mineral preparations for the first time after the procedure. In the future, use nitrogen fertilizers during active growth, potassium and phosphorus fertilizers during the flowering period.

So, we looked at what to do if the orchid’s trunk turns yellow. By following all these rules, you will create favorable conditions for active growth and bright flowering of the orchid. An exotic flower will have good immunity and is not afraid of anything. And in the future, you will generally forget about diseases and health problems.

Symptoms of peronosporosis

Onion leaves lose their emerald color, becoming paler, with a clearly visible yellowness at the tops. The shape of the feather changes, becoming flat and ribbon-like. The tops of the leaves often take an arched downward direction. In damp weather, diseased green leaves become covered with a grayish or gray-violet dusty coating of fungal spores, which colonize new plantings with wind and rain.

The leaves continue to turn yellow and dry out. Plant growth stops. The fungal infection continues its “path” into the bulb. Planted onions or sets next year in the beds will produce new young leaves, which the same fungus will “get.”

Sources of infection

The “home” for peronosporosis is the affected perennial rhizomes of onions, the bulbs themselves, seeds, and post-harvest plant residues.

What to do?

It is necessary to observe crop rotation. Return onion plantings to problem beds after 2-3 years.

Apply manure only to the previous crop.

Do not overfeed plants with nitrogen fertilizers. Use mineral fertilizers with increased doses of phosphorus. On poor lands, apply nitrogen fertilizers at the beginning of growth, in the second half of the growing season - phosphorus-potassium fertilizers, which increase resistance to disease.

Before planting onions (onion sets), it is useful to do thermal disinfection. The onion should be heated at 40-45°C for 24 hours. You can soak onions before planting in solutions of copper sulfate or other fungicides.

First aid

At the first signs of disease, onions should be treated with HOM (40g per 10l of water) or RIDOMIL (25g per 10l of water). You can repeat the treatment after one or two weeks.

When 3-5 onion leaves appear, you can spray the plantings with a 3% solution of potassium permanganate 2-3 times every 7-14 days for prevention.

You cannot treat onions for “greens” with any preparations.

Drying roots inside the pot



Over or under watering can cause yellow orchid leaves.

The simplest explanation for why orchid leaves turn yellow is the death of old leaves. In some varieties (cattleya, phalaenopsis, patheopedilum), over time the lower leaf becomes yellow and dries out. In orchids of the Dendrobium nobile variety, all the leaves from the flowering bulb may turn yellow or even fall off. In these cases, the appearance of yellow leaves is associated with the natural process of their death. Once the sheet is completely dry, it will fall off and can be removed. It is not necessary to cut off leaves that begin to turn yellow in advance.

The next reason why an orchid's leaves turn yellow is overwatering. An orchid is a resilient flower; it can withstand both a long absence of moisture and prolonged intensive watering. However, after a few months of such care, the plant will need to recover.

Signs of yellowing orchid leaves from excessive watering:

• the appearance of dark spots on the leaf;
• leaves lose their elasticity and become loose;
• all the leaves above and below begin to turn yellow;
• the trunk of the plant becomes covered with black spots;
• the flower sits loosely in the pot;
• the roots of the plant turn black or become invisible through the walls of the transparent pot.

If these signs are present, it is necessary to remove the plant from the soil, carefully examine the roots and, depending on their condition, carry out restoration measures.

Orchid leaves also turn yellow due to insufficient moisture. The leaves fade, gradually turn yellow and dry out. You can evaluate how moistened the soil is using a wooden stick. It must be carefully placed along the wall of the flowerpot. If after a few minutes the stick becomes wet, it means the soil is sufficiently moist, and the leaves turn yellow from excess moisture. Experienced orchid lovers know how to determine soil moisture by weight - if the pot feels light in your hands, then it’s time to water the plant.

Orchids in transparent pots with the correct watering regime have greenish-pearlescent roots, and condensation does not accumulate on the walls.

If the soil is dry, the plant needs to be watered. If the leaves continue to turn yellow, you need to free the orchid from the soil, evaluate the condition of the roots, replant if necessary, and monitor the watering regime.

Orchid leaves turn yellow from sunburn

The leaves of an orchid turn yellow if the plant is on the south or west side in hot weather. The leaf gets sunburn, the area affected by the rays turns yellow over time and gradually dries out, but does not spread further. It is necessary to protect the orchid from direct sunlight.

When the plant does not have enough light, the orchid's leaves turn yellow at the base and then die. The junction of the leaf and the stem may be affected. In this case, the diseased leaf must be removed, and the top must be cut off if the stem has turned black. The cut areas can be treated with iodine or brilliant green, and the instruments must be disinfected.

Other reasons why orchid leaves turn yellow

Orchids need potassium and iron. A lack of these elements may be another reason why orchid leaves turn yellow. In this case, fertilizing with iron-containing compounds and potassium is needed. If tap water is used for irrigation, then with the help of peat the plant will be able to take iron from the water.

The lower leaves of an orchid growing without a substrate may turn yellow from a root burn. This means that the amount of salts and fertilizers significantly exceeded the norm.

Water hardness is also the cause of yellow leaves. Gradually, the soil will become salty, iron will not be supplied to the plant, the lower leaves, and then all the others, will begin to turn yellow and fall off. In this case, the soil needs to be replaced and the leaves treated with liquid fertilizers. Distilled water must be diluted with tap water in equal proportions.

Proper and timely care of the orchid guarantees a healthy appearance and magnificent flowering.

Let's find out why the leaves of the Orchid flower turn yellow. Improving the appearance of the plant!

Orchid is one of the most capricious plants. Some types are easier to care for, while others require special attention immediately after purchase.

Regardless of the type of flower, yellowing of the leaves is considered one of the most common problems.

Orchid leaves turn yellow after transplantation

It is recommended to replant the orchid in new soil after the first flowering or one year after purchase. In some cases, this process is carried out earlier, for example, if the roots of the flower have become outside the pot or the soil has decomposed ahead of time. After replanting, yellowing of the leaves may occur. This happens in cases where the container is selected incorrectly, the soil is not suitable for the flower, or the rules for caring for the orchid are violated.

Before transplant any variety of orchid, you need to study all the relevant information or consult with specialists. Flowers of this species are capricious and all manipulations with them must be carried out with caution.

When transplanting an orchid, you must carefully inspect the roots. If there are rotten, dry or damaged shoots, they should be removed. Otherwise, the plant may die due to the progressive process of rotting or drying.

The natural aging process of leaves

You can determine the natural change of orchid leaves by the location of the yellowed elements. If the process starts from the bottom, then there is no reason to worry. Over time, the lower leaves of the flower become dry and fall off, ending their life cycle. There are varieties of orchids that, during dormancy, completely lose their green appearance and become like dry branches that have completely lost the ability to live. One of these species, for example, is Kalanta. The dormant period for these plants most often lasts from October to February.

The natural aging process of leaves orchids can occur at intervals:

• once a year;
• Twice a year;
• once every five years.

When a typical aging foliage there is no need to take special measures. Yellowed castings fall off on their own or are easily removed from the stem. Features of the resting period of an orchid and the approximate timing of changing green parts can be found out from flower shop sellers or, knowing its variety, can be found in specialized literature, as well as other information resources.

Reasons for yellowing of the plant and what to do to avoid wilting:

Improper watering

Orchid leaves may turn yellow overwatering, and from lack of moisture. According to statistics, most plants die for the first reason. In addition to yellowing and falling leaves, orchids get bacterial or fungal diseases when overwatered. Signs of overwatering a flower are soft and damp leaves, on which black dots or spots often appear. Dark areas gradually spread throughout the plant, including the roots and trunk. The orchid itself seems to be floating in the soil and is in an unstable state.

Rules for watering orchids:

• Do not water the orchid at the first signs of drying out of the top layer of soil;
• the degree of soil moisture and the need for watering is determined with a wooden stick;
• experienced gardeners determine the watering time by weighing the pot with the flower in their hand.

At lack of moisture the orchid also loses its leaves. The main difference from excessive watering in this case is the dryness of the foliage (in the first option they are wet). First, the tips begin to turn yellow, and then the yellowness spreads throughout the entire leaf.

The cause of yellowing of orchid leaves may be poor quality and hard water. The presence of rust or chlorine in the liquid harms the plant and shortens its life. Water the orchid with water at room temperature, add special fertilizers if necessary, and be sure to let it sit before use. Distilled types of liquid can be used, but they must be diluted in equal proportions with tap water.

Incorrectly selected pot and soil

The optimal type of soil for any variety of orchid is considered to be a mixture of bark, clay, sand, moss and mineral additives. Such soils are sold ready-made or made independently. Ordinary soil or flower compositions are not suitable in this case.

Regular watering with special fertilizers is a prerequisite for keeping orchids. Due to a lack of potassium and iron, the leaves begin to turn yellow and fall off. If the use of fertilizing does not restore the healthy appearance of the flower, then you should look for another cause of dry leaves.

Orchid pot It is better to use transparent and relatively small size. The best option is a container with a diameter of 12-15 cm. The exception is large plants. The transparent walls of the pot will help you monitor the condition of the plant's roots and determine the need for watering.

Orchid leaves turn yellow due to lighting

Choosing the right lighting for an orchid is a complex issue. On the one hand, the leaves of the plant may begin to turn yellow due to lack of light, on the other hand, they may become damaged as a result of sunburn. Recognize sunburn not difficult. The first sign can be considered the appearance of yellow spots or stripes that partially dry out the leaf at the site of the lesion.

If the leaves of an orchid are damaged by sunlight, it is necessary to move the plant to a less lit place. There is no need to remove the casting. The process of their final drying should occur naturally. Once there is no greenery left on the leaf and it looks completely dry, you can remove it.

When there is not enough light Not only do the orchid leaves turn yellow, but the color of the stem also changes. It is more difficult to preserve a plant damaged by improper lighting than after receiving burns. If the stem begins to dry out, you will have to cut off the affected part and start growing the flower almost all over again. The cut area must be treated with brilliant green or iodine.

Fusarium rot- a common disease of orchids, accompanied not only by yellowing of the leaves, but also by their preliminary curling. The appearance of a gray tint to the leaves indicates 100% infection of the flower with a dangerous disease.

Bacterial spot determined by the presence of wet ulcers on the leaves of the orchid. In this case, yellowing occurs at a rapid pace, and the oozing wounds do not disappear until the leaf completely dries out. Plaque on the leaves in combination with their yellowing is a sign of the presence whiteflies. Yellow leaves combined with dry shoots and roots - root mite

Regardless of the disease identified in the orchid, the principle of treatment is the same in most cases. Firstly, the plant is isolated from other flowers. Secondly, all affected areas are urgently removed. Thirdly, all sections of the cuts must be treated with iodine. Further treatment depends on the specific disease. Based on several characteristics of the flower’s condition, sellers in specialized stores will quickly select the necessary preparations.

Growth stimulants and fertilizers

Any preparations for feeding orchids must be chosen carefully. Incorrect dosage, too saturated formulations, excessive use - all these factors can cause not only yellowing of the leaves, but also the plant getting chemical burn. If signs of damage to the flower by fertilizers or growth stimulants are detected, it is necessary to temporarily stop using them.

Stressful conditions

Frequent rearrangements of the orchid from place to place, changes in lighting and air temperature are situations that are considered for the plant stressful. This type of flower must be handled with care and precision. Do not forget that the orchid, despite the fact that its homeland is the open areas of the islands, is one of the most delicate and fragile indoor plants.

An orchid, especially its Phalaenopsis variety, is a rather capricious plant that requires care and a lot of attention. Beginning gardeners often encounter the problem of falling and withering leaves of this tropical plant. In most cases, the problem can be quickly resolved by changing the conditions in which the flower is kept. To do this, you may need industrially produced “medicines” or preparations prepared at home.

Possible problems

Leaves are the most vulnerable place of an orchid, especially those of the Phalaenopsis variety. The most common problems are:

Each of these cases requires an individual approach.

Orchids often have problems with leaves

Decay

Sometimes the leaves of an orchid suddenly begin to fall off; they can spontaneously separate from the stem at any time. If all the leaves of orchids have fallen off, what to do depends on the condition of the root. If the root is affected by a fungal or viral infection (this usually happens when the soil is over-moistened), it is unlikely that the flower will be revived. Falling off can be caused by poor feeding. In this case, the situation can be easily corrected by regular application of complex mineral fertilizers.

Wither and turn yellow

If an orchid's leaves turn yellow and wither, not everyone knows what to do. Most often this problem is caused by the fact that the room (on the balcony) is too hot. The plant stops blooming, the flower stalks become deformed, and sometimes the stem turns black. At a temperature of 27-28 degrees, Phalaenopsis spends all its energy adapting to the heat and absorbing drops of water from the air, this has an extremely adverse effect on the condition of the leaves: they turn red, brown or yellow. The plant experiences air starvation and nutrient deficiency. When it gets colder indoors or outdoors, the leaves will look healthy again.

The yellow tint of leaf blades can be caused by a lack of nutrients and poor soil

Drying

The answer to the question of why orchid leaves dry is simple. The plant lacks moisture. In this case, increased watering will save the situation. After watering, do not forget about loosening so that the water does not stagnate in the soil. When the leaf blades are healthy again, the plant's moisture supply can be reduced.

Regular watering will help prevent drying out.

And others

Not all gardeners know why orchid leaves crack or become soft in the middle. However, this problem is quite common. Most often, cracks in leaf plates, as well as drying out, are caused by dehydration. However, there may be other causes: bacterial or viral infections. Mechanical damage can also be caused by pests: aphids, scale insects, spider mites. Because of this, the turgor of the leaf plates changes, they soften and darken. The leaves may even rot, become covered with mold or a sticky coating similar to moss, and the flower stops growing. In severe cases, the leaf plates are completely covered with a white coating so that even the veining is not visible; the leaf resembles a pattern made of white opaque paper.

Attention! The tricky thing about many viral and bacterial infections is that in the early stages they are almost invisible. The orchid is still actively growing and developing, but the disease is already sapping the plant’s strength. Only in the later stages, when the root is already deeply affected, do the leaves begin to wither (dry out at the edges, become deformed). In this case, there is no point in resuscitating the flower.

Main causes of diseases

Identifying the most likely cause of Phalaenopsis disease is quite difficult. Most often, the problem is caused by a whole range of different reasons. The most common of them are:

Infection with dangerous fungal, viral, and bacterial infections can be caused by transplanting a plant into a pot filled with soil brought from the street. Therefore, in order to prevent wilting or yellowing of the tips of the leaves, it is recommended to use only special soil for indoor plants, purchased from a specialized store.

Drying and wilting of leaves is very often caused by sunburn.

Attention! Phalaenopsis does not like direct sunlight, so experts recommend keeping the orchid in partial shade in the summer, otherwise the plant may be lost: the leaves will begin to curl and then dry out.

When choosing fertilizer, you should give preference to preparations with a high concentration of nitrogen, potassium, and phosphorus. It is these substances that the orchid needs to gain green mass, proper development of leaves, active growth and long-term flowering.

Most often, diseases are caused by improper care

Resuscitation methods

The most popular methods of combating orchid diseases are folk remedies. Their main advantage is that you don’t need to spend a lot of money on buying expensive drugs and poisoning a sick plant with “chemicals”. However, “grandmother’s” methods will not give immediate effect. They act much more slowly compared to industrially produced drugs. With regular treatment, folk remedies can be very effective. It is recommended to use them exclusively in the early stages of the disease.

Folk remedies

You can try folk remedies for resuscitating orchids without a growing point and leaves. The easiest way is replanting with partial cutting of the roots. To do this you need:

• Carefully dig the flower out of the old pot;
• Clean the roots from the old soil by cutting off all treated areas with a sharp knife;
• Move the flower into a new vessel with previously prepared soil and a nutrient mixture with the addition of a natural absorbent - charcoal and a drainage layer;
• Provide a support, as during the first time after transplantation the flower may lose stability.

After this procedure, the main task of the gardener is to provide the flower with a large amount of daylight and protect the Phalaenopsis from sudden temperature changes and drafts.

Attention! Another folk method also gives good results. The roots of the dug up orchid are placed in a vessel with water at room temperature. After 12 hours, the liquid is completely poured out. After the same time period, a new portion of liquid is poured into the vessel.

The procedure will be effective only if the room temperature is above 25 degrees. After 2-3 months, new roots should appear. However, this can happen even after six months.

Time-tested folk remedies give good results

Chemical

Flower growers often think about how to revive orchids without leaves but with roots. If leaf fall is caused by fungal diseases. Only chemical agents - industrially produced fungicides - will help. They quickly kill the fungus and prevent its reappearance. The drugs Gaupsin and Vitavax give good results. When preparing the solution, you must strictly follow the instructions. For all products it is approximately the same - the powder is diluted in half with the liquid:

• Heat the water slightly so that the medicine dissolves faster;
• Pour the liquid into a plastic bottle of mineral water or lemonade, filling the vessel halfway;
• Pour the powder from the bag into it, shake and stir until completely dissolved;
• Add the required amount of water.

After this, the prepared solution can be used to treat the plant at home. As a rule, two to three times are enough. However, if the fungus is active and the roots are severely damaged, treatment will need to be carried out for a long time. Then new roots will gradually appear to replace the damaged ones.

Biological methods

If all the leaves of an orchid have fallen off, experienced lovers of indoor plants know how to save the flower. Phalaenopsis responds well to biological resuscitation methods. In order to revive a flower, you can use biologically active additives - growth stimulants. The most popular of them is “Fitosporin”. It restores the plant’s vitality, promotes active regeneration of the orchid’s root system, and helps the flower adapt to adverse environmental influences. The drug must be prepared strictly according to the instructions on the package. The main advantage of phytosporin is that it does not contain aggressive chemicals. After treatment, the flower leaves will no longer fall off.

Further care for the orchid

If the plant was able to be revived, further care must be properly organized, otherwise the weakened flower will get sick again. To do this, it is necessary to prevent waterlogging of the soil and regularly feed Phalaenopsis. Good lighting is of great importance. To prevent new diseases, it is necessary to visually inspect orchid leaves as often as possible. Such an examination will help to promptly identify any symptoms of trouble: yellowing, fading or cracking. Do not forget about timely transplantation. If the foliage at the base of the stem begins to fall off, wrinkle or burst, immediate action must be taken, otherwise the orchid may dry out.

The main thing is not to repeat the mistakes that led to plant disease

Experts say that most problems in caring for Phalaenopsis are caused by an improper microclimate in the room. Therefore, if it is not possible to create suitable conditions for an orchid, it is better to choose a less capricious and high-maintenance plant. Phalaenopsis and other varieties of tropical “guests” need careful and delicate treatment.

As mentioned earlier, the causes of yellowing and drying of the peduncle can be divided into a natural process and the consequences of improper care. Both cases have their own solution and flower treatment. Let's look at these reasons in more detail.

Natural process

Are your orchid's leaves turning yellow? Don't be alarmed. The green mass loses its brightness after 3-4 years. The stem may also turn yellow or begin to dry out.

Such trouble may also indicate the age of the flower. When an orchid blooms for a long time and then fades, the stem may remain green and prepare for a new flowering phase, or it may turn yellow and dry out.

Whether to cut it in this case or not is a purely personal matter. But one cannot ignore the fact that sometimes the stem dries halfway from the top. This means that another, lateral peduncle may form.

If the owner wants the plant to delight with its flowering, it is necessary to leave the peduncle and not cut it. If the gardener prefers to preserve the decorative shape of the flower, it is recommended to prune the dried branch.

Consequences of improper care

Yellowing and drying of the phalaenopsis stem is one of the most popular problems. But don't be disappointed. First, you need to identify the cause of yellowing in order to try to get rid of it in the future.

Important! It is necessary to take into account all the subtleties of caring for an orchid in order to prevent its death. Having discovered any problem, you need to immediately begin to eliminate it. If treatment is not started in time, this can lead to the complete death of the flower.

Treatment

Don’t get too carried away with fertilizers and mineral additives. This can have a bad effect on the leaves and stem of the plant. If this rule is neglected, you must carefully rinse all the roots of the flower under running water and inspect them for damage.

Prevention

To avoid drying out of the peduncle and stem of the orchid, it is necessary to constantly carry out simple preventive work.

Here are some basic rules for caring for this capricious plant:

1. Do not place the flower in direct sunlight. Lighting should be diffused. It is better to place the orchid on the east or west side. A lack or excess of light can result in yellowing of the stem and leaves. In winter, artificial light can be used.
2. Air humidity into the room should vary between 65 - 75%. In summer, we must not forget about spraying the plant 3 times a day. In winter, do not leave in a draft.
3. Room temperature where the plant lives, it is necessary to maintain from +18 to +27 degrees.
4. Watering– this is one of the most important criteria in caring for an orchid. This capricious plant will tolerate drought, but will not survive excessive watering. Signs of excess fluid: yellow leaves and stems, rotting of the root system.

Attention! It is necessary to water the orchid only with soft water: boiled or rain. Under no circumstances should you water a flower with cold tap water.

To summarize, we can say that when purchasing a flower such as an orchid, you need to become familiar with all the vagaries of its care. Here you can’t get by with just watering once a week. This flower requires due attention.

Every orchid owner has at least once encountered in practice the fact that the leaves of a plant, its stem or buds suddenly, for no apparent reason, turn yellow, become lethargic and lifeless. Of course, this also affects the general condition of the flower; not all flower growers, unfortunately, know what needs to be done, and whether it is necessary at all. But it is undesirable to let such “diseases” happen. Any disease sooner or later affects the roots of plants, and our main task is to prevent this, to prevent the disease from going deep.

Before you start talking about why orchid leaves turn yellow, it’s worth clarifying what types of these beautiful plants are most often grown at home.

In residential premises it is customary to plant such varieties of orchids as dendrobium or phalaenopsis(epiphytic orchids), shoes or cymbidums(epiphytic), as well as Kalanta(ground orchid). For some reason, for the most part, the most popular among indoor flower lovers are dendrobium and phalaenopsis. The choice of amateur gardeners usually falls on these varieties, since they require minimal care. This is especially important if you have just started to get interested in planting flowers and do not yet have much experience in caring for them. The unpretentious dendrobium is perfect for noobs. Naturally, you, as the owner, will need to know all the “behavioral features” of your flower, including those related to care, seasonal changes, flowering and changing leaves.

How to care for an orchid?

Orchids do not require any too intrusive and careful care. They can easily live on the windowsill and feel good there with the correct watering regime and regular feeding. If you decide to arrange a separate “house” for them with all the conditions - an orchidarium - so much the better! It is advisable to do it in a bright room, and ideally after consulting with a specialist. However, even in the most luxurious conditions with all the “conveniences”, the plant can sometimes get sick.

Yellow leaves - are they dangerous?

In general, the yellowing of leaves in different plants in itself is not a reason to sound the alarm. Leaves regularly die and fall off; this is a completely natural process.

There should be cause for concern only if the leaves turn yellow too often, even when young, and if the yellowing covers a significant part of the plant's body. And also if there are any side effects - roots rot, buds fall off, etc.

To know for sure whether everything is okay with your orchid, experts recommend remembering how long the leaves of your orchid variety live. For example, if it is a phalaenopsis, then the “plumage” changes at least once a year. First the leaves turn yellow, then dry out, lose their shape and fall off. That is, if your phalaenopsis began to shed its lower leaves, know that everything is in order, it is just getting rid of dead cells. If we are talking about dendrobium, it is worth remembering that the norm for it will be to change leaves twice a year, most often immediately after it has bloomed, but sometimes during the dormant period.

Why do they turn yellow?

Let's move on directly to the conversation about why the leaves of an orchid turn yellow and what to do about it. This can happen for a number of reasons:

If an orchid's leaves turn yellow, the best treatment in this case would be to normalize the flower's life pattern and change its care depending on the reasons for the yellowing.

If you find that your orchids have yellowed stems and leaves that are wilting and falling off, if the body of the plant has rough rough spots and dark spots, and the bases of the leaves have taken on a reddish tint, this may indicate that it has been damaged by sunlight. In this case, it is necessary to place the flower in partial shade for a while. There is no need to make artificial darkening; it is enough to simply move the flower to the least illuminated area of ​​the living room. Bright light can have a particularly detrimental effect on thin and delicate leaves (by the way, phalaenopsis is one of the orchids with especially sensitive foliage). If the leaves have acquired a normal shade and no longer dry out, then the problem is over.

If you (or unscrupulous sellers at the flower shop) overdo it with fertilizers, your dendrobium may suddenly begin to wither after a couple of years. In this case, you should temporarily stop feeding and be sure to place the plant in a warm place. The first fertilizers should be given after a couple of weeks, reducing their dose by about half. If there is a suspicion that the orchids have received too much nitrogenous substances, you need to rinse the pot under running water. Typically, an excess of nitrogenous fertilizers is manifested by an excessive abundance of leaves and lush flowering of a still young plant. It can become very overstressed because of this and stop blooming altogether. Nitrogen fertilizers also have an aggressive effect on the roots.

As for watering, you need to carefully control the amount of moisture supplied to the plant, despite the fact that orchids love moist soil. And under no circumstances should you allow excessive watering after a long break. Certainly, It is desirable that the water used for irrigation be filtered. Yellowing buds can indicate excess liquid. Since it is to them that all the main amount of moisture comes, first they swell, then from an excess of substances they begin to turn yellow, then they dry out, and in the end they simply wither and fall off. Moisture and plant roots are not spared. In the photo you see the stem and roots of an orchid destroyed by water (this is a dendrobium).

Here, perhaps, are all the tips on how to avoid yellowing of orchid leaves. Nowadays, the Internet is replete with various videos that tell in detail about the proper care of orchids and other flowers. There are also collections of photos with detailed comments. In addition, you can always seek advice on what and how to do on forums, where, to complete the picture, you can also post a photo of your flower.

It is useful for any gardener to know why orchid stems dry out and what to do about this problem. There can be many reasons, but in 60-70% of cases it is natural aging. If we are talking about phalaenopsis, then the stem is usually called the peduncle, and if we are talking about dendrobium, then it is the bulb. Caring for orchids can be difficult, because some species are very capricious, but they are all afraid of changing their place of residence and are susceptible to new conditions. Immediately after purchasing a phalaenopsis, it is possible for the flowers to drop, the buds to turn yellow, and then the entire peduncle. This is a sign of stress that the plant has suffered due to a change in conditions. You shouldn’t be upset, soon the flower will adapt to the new features of its contents, grow green mass, roots, and after the growing season will release a new peduncle, therefore, when the stem of a phalaenopsis orchid turns yellow, you need to wait until it dries and then cut it off.

Natural process

For phalaenopsis, yellowing of the lower leaves is normal. The green mass lives for a certain period, for example from 3 to 5 years, when it expires, the leaf begins to lose hardness, fade, turn yellow, and soon dries out. Also a natural process is the drying of the faded stem. If your flower produced buds, then bloomed safely, dropping them after 3-6 months, there are two options for further developments: the peduncle either remains green, preparing for the next flowering, or turns yellow. Orchid lovers even argue about what to do when the orchid stem turns yellow, cut it off completely or until the next dormant bud? If the yellowness reaches a certain place and a piece of the peduncle dries out, but a part remains alive, it means that in the future your phalaenopsis is planning to grow a side peduncle or a baby from a bud. Flowering from lateral shoots on the stem will be less abundant and harmonious. Therefore, some flower growers immediately cut off the faded peduncle, so that if the bush spends energy on flowering, then only on gorgeous ones.

The situation with dendrobium is different. This is a sympoidal plant consisting of several bulbs. The one that has faded will no longer be able to please you with its inflorescences. Therefore, it is completely natural that if the stem of a dendolbium orchid turns yellow, only after that should it be cut with a knife. The next flowering of the bush is possible only from new shoots, which will appear some time after the buds have withered.

Withering growth point

The biggest problem that can arise with phalaenopsis is the death of the growing point. Since it is a monopoidal plant, it has only one growing point. If she dies, there is no chance of survival. Why can this happen? The most common cases of decay. Phalaenopsis are thermophilic and afraid of overflow. They should not be left in water for a long time, a maximum of a couple of hours. Within just a day, most of the root system can rot while in a liquid medium. Therefore, it is imperative to drain the remaining moisture from the trays after watering. The death of the growing point is indicated by the massive fall of foliage, and its color is putrefactively dark. The neck also acquires a dark color and becomes soft. All that remains is to throw away the remains of the root system. A longer process is the death of the growing point due to overdrying. Phalaenopsis can survive for a long time without water, but months are too much for it. The bush begins to suffer from dehydration, the leaves turn yellow, the root system dies, and then the growth point itself. If you are not sure that the orchid’s stem and leaves are turning yellow due to the death of the growing point, but it has dropped all its greenery, leave the pot with the root system for a month or two. It is possible that the lateral cervical baby will go, then your favorite flower will not disappear without a trace.
