Orchid is definitely a spectacular flower. A flowering plant is a bright and extraordinary decoration of any room. Only such an exotic beauty has a capricious character, it requires a certain attention. All because, the birthplace of the flower are tropical forests with a humid and hot climate. In our latitudes, orchids require additional care, otherwise problems with the beauty of the beauty will immediately arise.
Features of the plant
Most members of the genus Orchids, which are grown on window sills, belong to the epiphytic class. These are plants that live on trees or other plants, using them as a support. However, they are not parasites.
Foliage for epiphytes is of great importance. Not only thanks to the rhizomes, but also leafy plates, orchids maintain the water balance, receive nutrients. Leaves also take an active role in the process of photosynthesis.
Background of the problem
The first signs of falling leaves are yellowing of the plate, as well as blackening at the attachment points to the base. In the early stages, you can consider the problem, and what is the reason: natural or unnatural processes.
Another precursor is the appearance of roughness on the surface of the leaf, because a healthy flower has smooth and juicy leaves. This symptom indicates the beginning of the destruction of surface tissue. If you do not take any action, it is possible to lose a leaf.
The appearance of yellowed parts of exotus indicates a variety of diseases or aging. The main danger is not to delay, but at the same time to react at the first symptoms. In time to assist the diseased plant, since the consequences are fraught with:
- complete drying of the roots
- deterioration of the general condition against the background of infectious diseases,
- developmental disorder
- cessation of flowering.
Foliage becomes yellow, and subsequently disappears. The plant is in survival mode. And the loss of leaves, similar to the discharge of ballast, but also fall buds, blossoming flowers, dry peduncle, there are problems with the roots. This may indicate a variety of, even serious, health problems. Especially if this happens in a fairly short period of time. It is urgent to find out the cause of the error.
Natural and unnatural process
From time to time orchid sheds old leaves. In this process, there is nothing terrible, on the contrary, it is considered the norm. A similar process is associated with the life cycle of a plant. Sheet plate begins to gradually turn yellow, becoming a bright yellow color, then wrinkles, darkens and dries. First of all, the lower leaves turn yellow. Natural extinction occurs after 1-5 years.
Another green mass can change color, and later crumble, during flowering - the specificity of some Orchid varieties. Perhaps the flower is dormant, hibernating. This condition is also observed in not all varieties.
Differences of natural physiological processes from external factors in that:
- the bottom sheet dies off every 1-5 years,
- the process does not affect the general condition of the plant,
- no massive leaf fall.
A healthy leaf has a green color, it is strong, fleshy, firmly rests on the stem. If it turns yellow, fades or disappears, it is a signal that the normal life of the plant is disturbed, unless it is natural aging.
Orchids are somewhat capricious and capricious plants. They can react negatively to a change of residence, lighting, temperature and humidity drops — all of this is reflected in the appearance of the beauties. Therefore, it is not always easy to determine the cause of leaf fall, but it is still important. Main factors:
- indoor climate,
- poor nutrition,
- natural process
- wrong lighting,
- poor quality or old substrate,
- irrational watering
- non-standardized use of fertilizers
- inadequate water quality
- not suitable neighbors
- lack of optimal temperature and humidity parameters of air,
- damage by infectious diseases or harmful insects.

Why leaves fall in orchids, if all the leaves are green
Undoubtedly, such a phenomenon looks pretty scary (the flower throws off leafy ones), why does the orchid shed which, at first glance, look absolutely healthy? This can cause panic, especially among florists who do not have much experience in their favorite business.
Finding out the reasons should begin with determining the type to which the flower belongs, since some of them are able to maintain leaves for more than four years, while others lose them as soon as the flowering has ended. Therefore, if the orchid has dropped the leaves for this reason, then you should not panic, because this process is completely natural and should not be confused with a sign of a disease.
However, any changes that suddenly appear in the appearance of the flower should not be ignored. It is important to take action in a timely manner, because in addition to proper care, only this will help maintain the health of the plant.
Each plant periodically drops its foliage. This is an absolutely natural process, when the foliage falls, and the roots are alive, which has always been considered the norm. This is due to his life cycle. The sheet plate has its lifespan, by the end of which the sheet begins to lose its brightness, turn yellow, fade, dry and fall. Most often this happens with the leaves below (about once a year). With others, it occurs every four to five years.
Also, it is possible to determine the natural death of the leaves by the general condition of the flower, also in this case the leaves fall off not all at once.
Since this type of flowers is very fond of light, which is also necessary for the normal process of their vital activity, high-quality lighting is simply necessary. Otherwise, the plant can lose all the leaves, not only yellowed, but also absolutely healthy.
This is due to the lack of nutrients that the orchid receives not only through the root system, but also through the leaves that are actively involved in the process of photosynthesis.
If the flower is in the apartment so that the leaves do not fall off, the lighted side will be the most advantageous location for it.
The light should be bright, but at the same time scattered, so that there is no direct sunlight that can leave burns on a tender plant, which of course will have a detrimental effect on the general condition of the flower. In order for the light to be the most comfortable for the plant, in the summer period you can cover the windows with a special net or blinds, and in the winter use additional lamps.
Improperly selected soil can also cause orchid discomfort. For these plants, the soil should be purchased only in specialized stores, since any discrepancy with the conditions listed below leads to impaired flower development. The criteria by which the soil can adversely affect the condition of the plant:
- The soil was taken from the natural environment, therefore, may contain various infections, fungi.
- Acidity. Orchid requires a certain level of soil ph. That is why it should be chosen in strict accordance with the type of flower.
- Excessive moisture. When moistening a plant, it should always be remembered that overflow affects its condition much worse than underfilling.
In this case, the root system suffers, some of the roots become rotten and then rot completely.
An orchid, as well as any living creature, periodically requires additional vitamins and microelements, which is ensured by its growers in the process of fertilization. But not everyone knows that the violation of the feeding technique causes the flower to stress and its leaves fall away. Leaf fell away - improper fertilizer, such as its excess, can be the cause.
During the feeding period, you should follow the golden rule - it is better to underfeed than overfeed. Even despite the fact that these substances are useful. Since the fertilizer has a high concentration of various substances, with an overabundance of its root system can get burned, which often leads to the death of the plant. If you suspect that you have overdone it with fertilizing, you should exclude all types of fertilizers for at least two months.
Lack of beneficial substances can also lead to dropping leaves. First of all, the development of the flower stops, the appearance loses its brightness, the young shoots become weak, like the plant itself. As for the leaves, in addition to the loss of brightness and juiciness, they often turn yellow and shallow, which leads to their early fall.
In order to feed the plant went to the benefit, it is produced in accordance with the phase of its development, given also the time of year. For example, the off-season (during this period the plant is in the resting phase) the flower is fertilized one time each week, whereas in summer and winter feeding will be enough once a month.
Also, the phase of active growing season requires nitrogen-containing and phosphoric substances, and the initial flowering process requires fertilizers containing potassium, which promotes the formation of buds. In any case, feeding the flower, you should strictly follow the instructions.
Water is the source of life, but its quality directly affects the health of the plant. For example, tap water often contains chlorine, which is detrimental to all living organisms. Therefore, when using water from the tap, it must first be defended or boiled.
Using rainwater for irrigation can also cause orchid leaves to fall. This occurs as a result of a large amount of harmful impurities that it contains. Especially the water formed during short showers. Therefore, it should also be boiled before use.
Also on the state of the plant may incorrectly affect violations of the conditions of its content, which includes the neighborhood with other flowers. Orchid, as the queen of flowers has a capricious and demanding character, loves a large space around itself. Therefore, the incorrect selection of neighboring plants, the energy of which depresses the orchid in an oppressive manner, leads to the fact that it can experience stress, at which all healthy leaves fall off. Yucca and all succulents belong to the “wrong” neighbors. Therefore, they should be kept in different rooms.
Pests and diseases
Violation of the rules of care also leads to various flower diseases. In this case, it is very important to identify the symptoms in a timely manner and start treatment as soon as possible, during which it is important to regularly perform a visual and tactile examination. Microbial or fungal diseases are difficult to cure, but quite realistic, whereas infectious lesions almost always lead to the death of a flower.
If the orchid has dropped the leaves, the reason may be that the air temperature in the room is not constant, its frequent drops occur and excessive humidity is present. This leads to the development of putrefactive processes. They are of several types:
- Black rot Visually determined by the presence of dark moist spots in the center of the leaf plate. Affected leaves are treated with a special preparation, or completely removed.
- Root rot. Its appearance contributes to a high degree of humidity. To combat the disease, a solution of a fungicide is used, which treats the soil and the roots of the plant.
- Fusarium rot. Detected by the presence of pink mealy plaque. Leaves are treated with antifungal effect.
- Gray rot. It affects flowers, aerial roots and leaves. Looks like a touch of gray. To eliminate the affected areas of the flower are removed, and place the cuts showered with crushed activated charcoal, and then twice treated with the drug fungicide.
Direct sunlight will burn the leaves, causing spots on them, and then the plate itself will die. Such leaves should be completely removed by treating damaged sections with colloidal sulfur.
Insufficient air circulation and high humidity in the room, excessive watering and poor drainage provoke stagnant moisture in the leaf axils. This is visually detected in the form of a yellow fluffy bloom and is a sign of powdery mildew. To eliminate the disease, remove the affected leaves and treat the plant with a special preparation.
In addition to the disease, the flower can also be destroyed by pests that often appear even in seemingly healthy flowers. Orchids are especially vulnerable to parasites that feed on plant sap (scythe, whitefly, red bug, aphid). The presence of insects can be identified by the appearance of small dark dots on the leaves and shoots of the plant. They are traces of punctures by insect proboscis. Parasites are easily removed by treating the orchid with soapy water.
Insects such as woodlice and slugs, despite the fact that they love dampness, they have a very negative attitude to water, therefore, to eliminate them requires abundant watering of the plant.
But mites (almost all species of these insects) have the most pernicious effects. Visually, it is impossible to notice them, as they are very small. The affected leaves dry up, having previously been covered with a bloom resembling a spider web. To combat them use a soap shower, as well as spraying with special means.
Instructions for saving leaves from falling off
What if the orchid has all the leaves? First of all, it is necessary to identify the cause and then eliminate it as soon as possible. For example:
- if the leaves fall due to poor-quality water used for irrigation, you should take measures to clean it (upholding, boiling, filtering, using purchased water),
- with the wrong neighborhood - move the flower to another room,
- If diseases or parasites are detected, the plant should be treated with special means.
- if the cause of leaf shedding is in poor quality soil - you should purchase suitable soil in a specialty store and transplant the flower.
Do not be afraid if something of the above happened to your plant. After eliminating the cause or cure of a plant, you gain an irreplaceable experience that will allow you to avoid mistakes in the maintenance and care of orchids in the future.
In a situation when the orchid began to actively shed the leaves, you need not to panic, but find out the cause of this leaf fall. Very often, it lies in the physiological and natural processes that occur at a certain time in this type of indoor flowers.
Orchid leaves have their own life cycle. Moreover, its duration depends on the type of plant. In some species, the flower will shed its leaves after 5 years, and in others a year after purchase. But for the most common home Phalaenopsis, this picture occurs with a frequency of 2-3 years.
The leaves fall off for natural reasons when their lifespan comes to an end and the plant needs updating. Therefore, if the leaves have fallen off the room orchid, and the care for it was correct, then it is a matter of a natural change of physiological periods. You just need to wait for the plant to form new leaves. In this case, no action is required.
Lack of lighting
Any living organisms, especially plants, are very sensitive to light. When there is a lack of light, potted flowers begin to “signal” with leaves. Therefore, if the orchid suddenly fell off a few leaves, you must first pay attention to the light mode. Particularly often leaf blades fall off after transferring the pot to a new growing place. Also, the location of a flower on the north side of the window can lead to leaf fall.
If an orchid experiences a prolonged lack of light, then it develops the following symptoms:
- green leaves gradually turn yellow
- after a while the leaf may start to dry,
- after that it falls off.
It should be noted that the lack of light is no less dangerous for these indoor plants than its excess. Orchids should not be in direct sunlight. In this case, they develop sunburn, which can also cause the leaves to die. However, in this case, the leaf plate is covered with brown spots in places.
If the lighting does not meet the requirements for growing these epiphytic plants, then very soon the flower simply dies.
Excess or lack of fertilizer
Если у орхидей наблюдается опадение листьев, то причина может крыться в неправильной подкормке. В этом случае проблема может заключаться как в недостатки удобрений, так и в их чрезмерном внесении. Признаками неправильно организованной подкормки являются мягкие листья желтого цвета. If the cause is not eliminated, then after a while they will start to fall off.
To make the flower feel good, and the roots get the full range of nutrients, you need to choose the right fertilizers (composition, concentration). It is especially important to conduct feeding in the period preceding flowering. After flowering, the flower enters a resting stage.
It is very important to monitor the content in the substrate of such elements as nitrogen, potassium and phosphorus. To them, the orchid root is especially sensitive. If you overdo it with their dosage, then the abscission of leaves will be a natural phenomenon. This is due to the fact that the root system at high concentrations of fertilizers receives a chemical burn, which leads to disruption of the process of absorption of nutrients from the substrate. At the same time, new and green leaflets will cease to form.
Therefore, when several leaves have already fallen with the corresponding signs of a lack of nutrients, it is necessary to urgently reconsider the scheme for adding flower dressings (especially mineral ones) to the flower pot.
Any orchid grown in the conditions of an apartment is quite demanding for watering. The plant does not tolerate excessive moisture, to which it reacts by the fact that its leaves fall off from the stalks. Also, not only the leaves, but also the core with the roots, suffer from an excess of moisture. It is important that the location of the junction of the leaf blade to the peduncle remains dry. Otherwise, the process of decay may begin and the new flower stalk will not grow.
Usually the problem with watering occurs in novice florists. After all, the orchid needs to be watered only as the substrate dries. In this case, watering should be abundant. Therefore, if you want to achieve a new green leaf, it is important to monitor the correctness of the organization of the water regime of the plant.
Periodically, the orchid needs spraying and warmth to the soul. To organize the shower, the flower is watered with warm water for 15 minutes. After that, the plant is placed in the bathroom until dry.
To prevent stagnant moisture in the pot, in its bottom should be drainage holes. If they were not there initially, holes must be made.
It is also necessary to choose the right substrate. If it dries poorly, then even with properly organized watering there is a big risk of rotting of the root system.
The orchid is watered only with well-settled water. Best of all it will boil. Otherwise, functional chlorosis may develop.
