Now it is difficult to find an apartment in which there would be no domestic plants, because flowers are always pleasing to the eye, delivering aesthetic pleasure. However, indoor flowers are susceptible to a variety of diseases, so you should always be prepared to take appropriate measures. In this article, we will tell you what diseases exist. indoor plants and how to cure them.
Viral diseases of indoor plants are diseases that are very difficult to diagnose, so they are considered the most dangerous. The main sign that your pet is threatened by a dangerous virus is a slowdown in plant growth, dry and yellow tips of the leaves (and then the leaves themselves). Often this is attributed to a lack of nutrients, but if other characteristic symptoms appear, there is no doubt that you are dealing with a viral disease. Unfortunately, there are no means by which a flower could be rid of an infection, so it can only be saved in the early stages of the disease.
To save your pet, you need to remove all the affected areas and lubricate the cuts with activated charcoal. They also disinfect all the tools with which you got rid of the affected elements. This is the only way to save him from the disease, before everything has gone too far. If the plant wilts and loses leaves, and changing the conditions of detention does not help in any way, the only way out is to get rid of the affected flower, alas, there are no other methods of treatment.
mosaic disease
The first sign of mosaic disease are spots on the leaves. They are usually lighter or darker in color. Their appearance is directly related to the fact that the disease breaks down the chloroplast, which, of course, is reflected in the color. "Mosaic" disease was nicknamed due to the fact that these spots, which cover the leaves, add up to an intricate mosaic pattern. The leaves are severely deformed and wrinkled, in the end there is complete wilting.
leaf curl
On the leaves, you can find areas that look a little swollen. Small bulges and specks appear, gradually capturing the entire surface of the sheet. The leaves are wrinkled and curled, and the florets, if any, can be severely deformed.
Jaundice
As the name suggests, the leaves of the florets acquire yellow. In some cases, a pattern resembling concentric circles can be seen on the sheet plate. After some time, the yellowness on the leaves is replaced by brown spots, which is a sign of tissue necrosis. Flower growth slows down significantly, and the stems become very brittle due to excess starch. Due to such incredible fragility and withered leaves, the flower quickly loses its former beauty and only a faded shadow remains from its former charm.
Bacterial diseases
Bacterial diseases of indoor flowers are a very unpleasant phenomenon. They infect the flower, penetrating through wounds, damaged roots, or even the soil in which your pet is kept. They can also occur due to waterlogging of the soil, so keep an eye on the irrigation regime.
Most often, the signal that a bacterial disease has affected your plants is spots on the leaves. If a similar infection has been diagnosed in domestic flowers, it will be easiest to get rid of it with the help of fungicides. You can treat bacterial ailments with a solution of copper sulfate or Bordeaux mixture. If she was hit root system, remove the affected area and transplant.
Bacterial wet rot
An unpleasant ailment. Spots are its symptom. gray color, which spread over the sheet plate. They look like fungal stains, but are more vague and oily. Touching such a speck, you can feel that they are very soft and have an extremely unpleasant odor. This is not surprising, because bacteria contribute to the decay of tissues.
To get rid of rot, the affected areas are removed, and the healthy ones are treated with copper sulphate.
Bacterial spotting
It looks like a burn, because the small spots that appear on the tips of the leaves darken over time, and a border forms around them. It looks like the leaves are burned. These spots differ from spots caused by fungal diseases in that their boundaries are clearly visible. Fungicides will also help here, but first do not forget to remove the infected areas.
fungal diseases
Get rid of a fungal infection with a soda solution. To prepare it, one teaspoon of soda per half liter of water is enough. The sponge is moistened with the resulting solution and plaque is very carefully removed. Various fungicides are widely used.
powdery mildew
An unpleasant disease that is not easy to detect in the early stages. A gray coating appears on the leaf plate, at first it can even be mistaken for thin layer dust. Gradually, it eats into the leaf and acquires a brown tint. The affected elements of the flower wither and die very quickly. Topaz, Hom, Vectra and Bordeaux liquid will help fight the disease.
Gray rot
First, it affects the stem of the plant, and then it passes to the fruits and leaves. It looks like a fluffy gray coating. After some time, it takes the form of dry rot, tightly braiding the stems. Very similar to mold, provokes the death of tissues. As a result, everything above the affected area dies, because the circulation of nutrients stops. Treat with Fitosporin, after removing all infected areas.
sooty fungus
It is characterized by the presence of black plaque on the tips of the leaves and throughout the leaf plate. As a result, the plant is unable to breathe and absorb sunlight, which leads to its death. Soot fungus is treated with Fitosporin.
Red burn
Leaves and flower stalks are covered with red spots, where spore-bearing crusts can later be seen. There is a strong deformation of the leaves and subsequent decay of the flower. Get rid of the disease with the help of fungicides.
Anthracnose
Brown spots appear all over the leaf plate, and the tips of the leaves become dark. Brown color. Sometimes the leaves are simply covered with reddish spots, after which they are deformed and wither. For treatment, "Fundazol" is used.
Rust
The leaves are covered with orange tubercles, and from the back of the leaf they look like bulges. The spots grow, capture the entire leaf, which causes it to wither and fall off. They fight rust with Bordeaux liquid and Vectra.
root rot
The fungus infects the root neck and blocks the access of nutrients to the rest of the flower. If the plant is young, the disease destroys it very quickly, and medicines cannot help here.
Wilt
The leaves are covered with dry brown spots, they dry and fade very quickly, even the vessels turn brown. Treat wilt with fungicides.
late blight
A disease that causes tissue necrosis. Purple patches appear on leaves brown rapidly spreading throughout the plant. From late blight will help get rid of drugs to combat late blight.
Video "Diseases of indoor plants"
In this video you will see the most common indoor plant diseases.
Most often, home plants suffer from fungal diseases and insect pests. First of all, the leaves and the root system are affected. By the characteristic signs of lesions, it is possible to determine the cause of diseases of indoor plants and eliminate it in a timely manner.
high temperature and high humidity- an excellent environment for the development of bacteria. For this reason, spraying and watering flowers should be done in moderation, as excess moisture increases the likelihood of the spread of pathogens.

Alternariosis
Alternariosis refers to diseases of a fungal nature, in which the leaves, tubers and stems of the plant become covered with brown spots. The causative agents are fungi of the genus Alternaria. The disease first affects the lower leaves, and then the lesion rises higher in concentric circles. Over time, the spots turn black and grow. Alternariosis especially progresses with sharp drops temperature.
The best environment for the development of microorganisms is a warm and damp microclimate, when the humidity in the room is 90% and the temperature is +30°C.
Prevention of such a disease is good ventilation. Ventilation helps fight mold. It also cannot be allowed high density shoots to exclude the source of bacteria: extra branches with leaves should be removed in a timely manner.
Anthracnose
The disease is caused by deuteromycetes of the genera Gloeosporium, Colletotrichum, Kabatiella. Spots on affected leaves may be different shade: sometimes they are gray-yellow, in other cases brown or purple. Growing, the spots acquire a brown tint. On them, spores are formed, which appear in the form of hairs. In these places, the surface of the sheet is rough.
The fungus is frost resistant and spreads with watering. Develops with high humidity and elevated temperatures.
In the initial stages of the disease, the affected leaves are removed, watering the plant is reduced in order to reduce humidity. Plants are sprayed with Bordeaux mixture, copper sulphate, Strobi fungicide.
Ascochitosis
Phytopathology is accompanied by the appearance on the leaves of small brown spots with a diameter of 1-2 mm. Growing, they darken, a yellow border forms along the edge of the spot. When the disease affects the stem, it fractures at the site of infection. The first signs of the disease are manifested in the form of drying of the tips of the leaves. A dark brown stripe appears on the border with the healthy part.
The fungus - the causative agent is very resistant, withstands frost and drought well. It is transferred with drops of water when spraying. Control measures are the same as for anthracnose.
downy mildew
The disease is provoked by the activity of fungi - oomycetes. At the initial stage of the disease, yellow spots of irregular configuration appear on the upper part of the leaf plate. After a while, they turn brown, and then turn brown. A gray coating appears on the lower half of the sheet, which then turns black. Diseased leaves gather in corrugations, turn yellow and fall off. In the later stages, the disease affects the vascular system of the plant. On the cut, this manifests itself in the form of darkened vessels.
Ideal conditions for the development of phytopathology are:
- high acidity of the soil substrate;
- high humidity;
- limited access to fresh air, poor ventilation of the room.
The source of the disease is poor disinfection of seeds and soil. In order to prevent the seeds before planting, they are kept in water at a temperature of +50 ° C for 20 minutes. Warm seeds are dipped for 3 minutes in cold water and then air dried.
The room is kept at low humidity. Bushes require constant thinning to improve air access. In order to disinfect the soil periodically need to be changed.
When the disease has spread to the plant, the infected leaves and side branches are removed. Spraying is carried out with Bordeaux liquid, Bravo or Quadris preparations. If the soil is already infected, then spraying is excluded.
To avoid powdery mildew, houseplants should not be fertilized nitrogen fertilizers, especially when the budding process is underway. Since spores easily travel considerable distances, bacteria can be introduced from trees located outside the window. The development of the disease is affected by a lack of air, but drafts are also contraindicated. You can treat the affected buds with sulfur, whey or milk.
rust on leaves
With this disease, rusty spots appear on the leaves. If you rub them in your hand, they form a powder. This disease also applies to fungal infections. It appears as a result of abundant watering, lack of sufficient lighting and lack of fresh air.
Sometimes the disease enters the ground along with the seeds. It is impossible to recognize it in advance, therefore, before planting, the soil and seed are treated with potassium permanganate. The spores of the fungus can be carried by the wind if the flower pot is placed on the window. Therefore, in the spring, all plants should be treated with Bordeaux mixture for prevention purposes. If rust has affected a small part of the leaves, they should be removed.
The appearance of rust spots can be caused by incorrect dosage of fertilizers. If the soil substrate has not changed for a long time, the soil should be completely replaced.
Flower growers become very annoying when their favorite plants suddenly start to hurt. Therefore, it is useful to learn about what diseases of indoor plants are and how they should be properly treated.
This topic is especially relevant today, because modern market offers great amount drugs and remedies that help prevent and eliminate flower ailments.
Bacterial and viral diseases
These diseases are often accompanied by slow development ornamental crops. It is very difficult to diagnose them in the early stages.
Viruses are often carried by thrips and aphids. Treatment in this case should be complex.
The most common diseases of indoor flowers:
- Rot. Flowers with fleshy leaves and stems often suffer from it. An overdose of nitrogenous top dressings or waterlogging can provoke the development of rot.
- Withering. In this case, the stems begin to wither first, after which all other parts are affected.
- spotting. Dead areas appear on the leaves with this disease. The spots have clear outlines that make it possible to distinguish them from fungal infections. To treat the disease, indoor flowers need to be treated with special preparations.
- bacterial cancer. Symptoms of the disease involve the appearance of small growths on the shoots and rhizomes of plants. If these tumors are left unattended, they can cause their death.
Chemicals for treating home flower disease are not effective enough. In such situations, it is important to observe preventive measures and control soil moisture.
If rotting of the rhizome was found, then watering should be reduced, and if the whole flower is sick, then it will have to be removed along with the pot and soil.
Prevention measures
- You need to buy flowers exclusively from trusted sources (nurseries or specialized stores). In this case, when pests appear, it will be possible to seek help from the seller, who, most likely, will fix the problem for free.
- It is desirable to choose varieties of crops that are distinguished by good resistance to ailments.
- Seed material for planting must be disinfected and sorted.
- It is necessary to adhere to the conditions of care depending on the type of plant.
- Flowers and leaves should be inspected as often as possible for damage and disease.
When a disease is detected, the flower must be urgently isolated from the rest and begin to deal with the problem.

Various spots often appear on indoor plants, the cause of which is sometimes difficult to identify for a beginner. Let's figure out together what it could be.
Plants are living organisms, but they are not able to complain about dis comfortable conditions content. Sometimes excessive care affects them even worse than lack of attention. Each individual species should be cared for in its own way. There are more or less whimsical varieties, but spots can appear on any house plant. The reason for this is the wrong growing conditions.
Wrong temperature setting
reddish, brown or too light(almost white), spots with a dry crust are the result of a transferred sunburn. The plant must be moved to the shady side of the apartment or to limit access to direct sunlight. As such, the burn is not dangerous for further growth. If necessary, damaged leaves can be removed.
White spots say that the plant is frozen. This happens in winter time if the pot is on the windowsill and the curtain does not let enough heat out of the room. It is more expedient to transfer the culture to more comfortable conditions before the onset of warm days.
The same damage can be the reason that too much was used when watering. cold water. Houseplants should not be watered with running water, it should settle and warm up to room temperature.
Lack of systematic watering
Black-brown dry spots on leaves or edge darkening talking about lack of water. Increase watering intensity or increase air humidity. Soft dark brown damage, on the contrary, indicates excessive moisture. Checking the soil by touch, you can pick up optimal mode glaze.
crustaceans spots on leaves and stems they talk about the lack of systematic watering. If the plant is in a dark place, then such growths can indicate high humidity in the room.
Wrong top dressing
Appearance black spots can be caused by two reasons:
- excess fertilizer;
- old age soil in a pot.
In the first case, it is enough to clarify the dosage of fertilizer for each particular flower and subsequently feed the houseplant in moderation. If the substrate has changed for a long time, the plant should be transplanted. After these actions, the leaves should regain their original healthy appearance.
Yellowness on the leaves is the first symptom of chlorosis. Violation of the formation of chlorophyll occurs due to incorrectly selected fertilizer. In this case, the leaves lose color, only the veins remain green. The plant gives a signal that it lacks magnesium or iron. Feeding indoor plants with calcium complicates the absorption of trace elements. Appropriate additives should be purchased and softened water should be used for irrigation.
Some plant species respond by yellow spots when water gets on the leaves. The same can happen if some kind of aerosol is sprayed near the culture. When exposed to chemicals, the leaves turn yellow.
plant diseases
Diseases fungal origin often cause spots on the leaves and stems of plants different color and size. There is a huge variety of diseases, each of which is treated differently. If the plant is already adapted to environment and strange spots suddenly appeared on it, although nothing had changed in recent times, it is worth studying in more detail the symptoms of the most famous diseases.
Home flowers are not able to explain in detail which conditions suit them best. But they skillfully give signals when something goes wrong. Experienced flower growers quickly find solutions. Sometimes experience is gained by trial and error, but it is much more effective to study the recommendations for caring for plants and constantly monitor the growth of green pets.

Sometimes improperly created conditions, their changes or violations of the rules of care are to blame for the occurrence of houseplant disease. Sometimes the fault for the appearance of a disease of indoor flowers lies entirely with pests, but, be that as it may, in order to apply the correct treatment, the disease must first be recognized.
There are four main factors that affect the life of houseplants: light, temperature, moisture, soil. For each type of requirements for all these factors are different. different plants need different amount Sveta. In addition, it is of great importance how many hours a day of light lasts. It is very important to create conditions that meet the requirements temperature regime and humidity level. The soil, in addition to fulfilling the function of nutrition with basic substances, must also have an acidity level exactly the same as that required by each plant.
Violation of the conditions of detention or the initial creation of incorrect conditions weakens the plants so much that it becomes the main factor in the development of diseases. Many diseases of indoor plants may well develop from a sharp change in temperature, for example, when it drops by 7 to 10 degrees in conditions of humidity, flowers are threatened fungal diseases, because the smallest spores-causative agents can penetrate into the cleanest apartment.
A room is not a fortress, sometimes pests penetrate it, but they are dangerous in themselves and still carry many diseases. If plants are weakened by poor maintenance, then they are all at risk. Therefore, it is necessary to monitor the level of temperature and humidity, maintain the desired acidity and nutritional value of the soil, and provide flowers with the optimal amount of light. Otherwise, they will show insufficient conditions and care, or become ill.
In the early stages of the disease, you can try to fight it by removing the affected parts of the plants, good care, care and love work wonders. It is necessary to make a strong pruning, treating all sections with activated charcoal. But a neglected disease will kill the plant, there are no drugs that can cure it. Most often, blooming exotics, primrose, begonia, bougainvillea suffer from viruses. Tools, utensils, a place - everything that a flower affected by a virus has come into contact with must be disinfected in order to stop the spread of the infection and protect the rest of the flowers. The affected flower must be quarantined.
mosaic disease
With this disease, the chloroplast disintegrates in the leaf cells, which cannot but affect the color. Discolored yellow or very light spots appear on the leaves, they gather along the veins, then spread throughout the leaf plate.
leaf curl
Currant often suffers from curliness, in the garden you can observe how on its leaves appear small areas as if swollen. Bulges appear on the leaves, they wrinkle, curl. Pests can infect indoor plants with this virus, they have a very similar effect of leaf deformation.
Jaundice
Jaundice in the early stages of the disease is confused with chlorosis. Leaves lose their juicy green color, turn yellow, wither, sag lifelessly. 
Then they start to appear brown spots- this is a manifestation of tissue necrosis. Stems can break under the weight of branches and leaves because excess starch accumulates in them. The plant finally loses its decorative effect, turns into a sluggish, breaking one, if it manages to bloom, then the petals will be colorless.
Video “How to protect flowers”
From the video it will become clear how to protect your home flowers from attacks by pests and diseases.
Bacterial diseases
Bacteria are the causative agents of very unpleasant diseases in all living organisms, this applies to animals and flora. Due to their very small size, they spread easily and imperceptibly, we ourselves bring them into the apartment on clothes, shoes, our belongings, and even on our own body. They enter the body of home flowers through wounds, seeds or tubers may already be infected when we bring them home. If the infection got into the soil, then it spreads very quickly through the vascular system of home flowers. Bacterial infection is manifested by spots on all parts of the plant, but most often the appearance of spots is noticed on the leaves. 
Bulbous and tuberous plants suffer from bacterial contamination more often than others. Treatment of this ailment involves quarantine and removal of the affected parts of the plant (with the treatment of sections with crushed coal), reduction of watering and humidity levels, and the use of fungicides. Even if the root is damaged, all the rot is cut out, and the rest is transplanted into new soil, at first they do not water it at all or do it very carefully. Good results are shown by the use of copper-containing preparations, namely "Copper vitriol", "Bordeaux liquid". Some use "Trichopol".
Bacterial wet rot
Diagnosing bacterial diseases can be difficult because, at first glance, they look like fungal diseases. But you need to take a closer look, the spots look more oily, with blurry contours. First, on the leaves, and then on all other parts of the plant, shapeless damp-looking spots appear, if touched, they turn out to be soft, sour with an unpleasant odor. This happens because bacteria, penetrating into the tissues, cause them to rot.
Bacterial spotting
This disease is also called bacterial burn. 
Small wet spots may appear first along the veins of the leaves, then they darken to black, acquire a yellow or brown border, in general, give the impression of a burn. First of all, the upper young leaves suffer.
fungal diseases
Mushroom spores are very small, they can easily spread around the apartment, infect other plants, so you need to be very careful, it is better to take quarantine precautions.
Dealing with troubles in turn, first they free the plant from pests, then they are mistaken for a fungus. Reduce watering for an infected plant, avoid spraying, reduce humidity and air temperature as much as possible.
If the lesion is not too extensive, then the spores can be simply removed without injuring the plant. To do this, prepare a soda solution: 0.5 l of water + 1 teaspoon of soda, moisten a sponge in it or soft tissue, remove plaque. You can use vinegar or beer instead of a soda solution: take 1 teaspoon of vinegar per 1 liter of water, and beer is only slightly diluted with water. If it’s not so easy to get rid of spores, then you will have to cut the plant, removing all parts with a bloom. 
Since the spores feel great in the soil, it must be replaced, sometimes at the first sign of the disease, replacing the top layer of the soil helps (if the spores have not yet penetrated very much into the plant itself), however, this will not help with root rot.
For treatment, use blue vitriol”, “Bordeaux liquid”, “Colloidal sulfur”. Both in the garden and on the windowsill, the fungicides Strobi, Topaz, Kuproksat, Vectra do well with fungal diseases. Many experienced growers are advised to apply Green soap”, unlike all of the above, it is harmless, which is important for indoor plants, in addition, it copes well with diseases such as scab, late blight, powdery mildew, rust.
powdery mildew
Violets, geraniums, cyclamens, petunias often have this unpleasant disease. On the outside leaflets appear powdery coating, at first it is easily removed with your fingers, like dust. Then, somehow imperceptibly, it stops filming, appears on the underside of the leaves, turns brown. Leaves stop growing, wither, die.
Gray rot
Gray rot also loves violets, geraniums, petunias, cyclamens, but brown wet dots and specks with a grayish-mossy coating appear on the stems, and not on the leaves.
Growing on the stems, the fungus blocks the access of moisture and nutrients to the leaves, the result without treatment will certainly be deplorable.
sooty fungus
The mob, as it is also called, settles on coffee trees, citrus, gardenias, azaleas, camellias, palm trees. They notice it when a black coating appears on the leaves, like soot, it grows rapidly, clogging the pores of the leaves. The result is an inability to eat and absorb sunlight, all of which will invariably lead to death if the plant is not treated.
Red burn
Amarylis, hippeastrum and other bulbous flowers often suffer from this disease. 
The pathogen lives in the bulbs, and its activity manifests itself on the leaves - at first, red spots appear, which darken over time, as if a black crust tightens the burn. Young leaves, shoots, flower stalks are deformed, bent, if left untreated, the plant may die.
Anthracnose
Scab affects the leaves of ficuses and palm trees. In the center of the leaves or along the edges appear dark spots different color, different shapes, they become slightly fleecy to the touch. A border of a different color appears around the spot, the spots grow, the leaf dies.
Rust
Rust is more common in the garden than on the windowsill, but still rusty spots on the upper part of the leaves of chrysanthemums, citrus fruits, camellias, pelargoniums, asparagus are sometimes found. 
If you turn over such a leaf with colored rusty spots, then on the underside, spores of fungi will certainly be found, hidden in growths similar to tubercles. These spots are a short time merge, become stripes, the leaves die off.
root rot
The roots of immature plants, cuttings grown from tender succulent stems, for some reason, pelargonium roots often suffer from root rot. The root neck is affected by fungi, nutrients not available to the plant.
Wilt
With high humidity in a warm room, the plants suddenly acquire dry spots on the leaves, the leaves darken, turn brown. Even the vessels become brown.
late blight
Excessive moisture, old compacted soil can contribute to the infection of cacti, succulents, azaleas, orchids with this dangerous disease. Purple and brown color on the leaves is the beginning of necrosis, then it captures the stems, root neck, and can quickly lead to the death of the plant.
Prevention
Crowding usually harms plants, flowers need Fresh air, optimal (and not excessive) humidity. "Fitosporin-M" is perfect for preventive watering to protect plants from fungal diseases. 
We must not forget to change the soil, sometimes disinfect it. Be sure to disinfect all tools that are used in working with plants. And the places of cuts in flowers need to be treated with crushed coal.
Healthy plants are much less likely to become infected, tolerate them easily, which means that you need to follow all the rules for caring for flowers, create favorable conditions, timely pest control.
