Diseases of indoor plants. What to do if the leaves of an indoor rose turn yellow and fall off Flowers leaves fall off

Many gardeners love ficus plants not only for their external beauty, but also for their unpretentiousness, because these plants do not need to be watered, fed and replanted often. But, despite this, certain difficulties with growing ficus still arise. Most often this concerns leaf falling.

In this article, we will give the main reasons that may explain why the ficus sheds its leaves, and what measures should be taken to ensure that the plant remains green.

Why do ficus trees shed leaves?

Beginning gardeners may be concerned about the falling leaves of the ficus plant. If this process occurs in late autumn or early winter, there is no need to worry - this is an absolutely natural process.

In the cold season, most varieties of this crop enter a period of vegetative dormancy and begin to change their green cover, shedding the old one. In this case, new leaves are formed almost immediately.

In addition, abscission may be associated with the age of the plant. As a rule, the green parts of the crop live for two to three years, after which they are renewed. But, if your flower is relatively young, and the cold season has not yet arrived, and the leaves are falling off the plant, you should think about external factors that could trigger this process.

Why does ficus shed its leaves?

Shedding leaves is considered an absolutely natural process of renewal. In some varieties it begins with the lower tiers, which gradually turn yellow, dry out and fall off (Figure 1).

Figure 1. Natural leaf changing process

In other species, with the onset of winter, all the foliage may fall off. There is no need to worry about this, since new parts are formed almost immediately. But it often happens that leaf fall is associated with negative factors environment, which must be eliminated to preserve the decorative nature of the crop.

Why do ficus leaves fall off?

Despite the fact that ficus is considered a relatively unpretentious plant in terms of care, some actions of the gardener can lead to the fact that the leaves of the crop begin to fall off.

If such a problem has already happened to your flower, eliminate the negative factors one at a time in order to accurately determine the cause and eliminate it. We will describe the most popular causes of abscission below.

Air temperature

Under natural conditions, ficus trees grow in the tropics, so drafts and low temperatures influence them extremely negatively (Figure 2).

Note: The root system of a flower is especially sensitive to cold and drafts, so placing a pot with a plant on a cold windowsill is not recommended.

The most comfortable temperature for the crop is considered to be +20 degrees, but there are varieties that require higher temperatures for normal growth and development. But you shouldn’t overheat the flower: if the room temperature exceeds +28 degrees, the leaves will begin to wither and lose color.

Improper watering

These tropical residents react extremely negatively to excess moisture. And if water begins to stagnate at the roots, they will begin to rot. If appropriate measures are not taken in time, the plant will first lose its greenery and then die completely.

Figure 2. Result of ficus overheating

To prevent this from happening, you need to strictly follow the watering schedule. In general, the plant does not need to be watered too often. To check the need to add moisture, just pierce the substrate with a thin wooden stick. Ideally it should remain dry. This means that the soil has dried to a sufficient depth and the flower can be watered.

Humidity

In winter, during heating season, the air in the room becomes too dry, which negatively affects the ficus. Similar processes occur in hot summers without rain.

Such conditions can cause leaves to yellow and drop (in dwarf varieties) or the formation of characteristic spots of representatives large varieties. To prevent such a problem, you need to periodically spray the plant with water. room temperature(preferably morning and evening) and wipe the green parts with a damp sponge from time to time.

Presence of pests

It often happens that the gardener simply did not notice that there were insects in the pot. But their presence will not remain without a trace. Most pests feed on plant sap (aphids, spider mites and scale insects). Accordingly, the culture loses vitality and simply cannot maintain foliage.

If you notice that your flower is beginning to shed its leaves, carefully inspect the soil and above-ground parts of the plant. This way you can detect insects and take measures to eliminate them. Thus, aphid colonies most often settle on stems and inner surface plates, spider mites form a characteristic web on the above-ground parts, and scale insects stick to the stems and leaves, and outwardly resemble brown growths.

To remove pests, you must first wash the plant with soapy water (followed by rinsing clean water) and spray with special insecticides (depending on the type of pest detected).

Fungal diseases

If the ficus not only began to lose leaves, but also changed color, there is every reason to suspect fungal diseases. IN in this case foliage can not only change color, but also become covered with pigment spots or stripes.

As a rule, fungal diseases occur when the plant is not properly cared for, or when an infected substrate is used for replanting. You can’t hesitate: to save the plant, you need to immediately treat it with fungicides.

Pesticides

The fact is that the flower itself is quite resistant to diseases and pests, and such troubles most often occur when the plant is not properly cared for. Therefore, if you fertilize too often and intensively or treat the flower with pesticides, the plant may simply not withstand such a load and begin to shed its leaves.

Transfer

The only one characteristic feature ficus, which greatly distinguishes it from other indoor crops, is its strong intolerance to transplantation or change of location. Even if you just moved the pot of the plant, its leaves may begin to fall off.

This also applies to transplantation. It is advisable to carry it out in early spring, when the crop has not yet awakened after a period of vegetative dormancy. But even in this case, it is possible that after replanting the leaves will begin to fall off. Don't panic: you need to leave the flower alone for a while, and after about a month, add fertilizer that will help the plant gain strength.

Poor lighting

As we have already said, in nature ficuses are found in the tropics, so direct sunlight and lack of lighting are detrimental to them. If it is dark, its leaves will gradually begin to become smaller and then fall off. With strong exposure to direct sunlight, signs of burns (yellowing) will first appear, and then the foliage may completely fall off (Figure 3).

Figure 3. Optimal lighting for a flower

To prevent this from happening, it is advisable to place the flower pot at some distance from the window so that the crop receives enough light, but it is diffused. Only such conditions will be suitable for this resident of the tropical forests.

Why do ficus leaves fall in winter?

In winter, most crop varieties enter a period of vegetative dormancy. Therefore, if you notice that your flower has noticeably thinned out, you should immediately water it intensively and feed it. Quite the contrary: such procedures will only worsen the situation.

It is important to remember that the falling of leaves during the cold season is an absolutely natural process, and soon new greenery will appear in place of the old foliage.

How to prevent

If you notice the beginning of leaf fall in time, and determine that this process is not associated with natural causes, you must immediately take action. certain actions to save the flower (Figure 4).

Here's how to prevent ficus leaves from falling:

1. Check the quality and degree of soil moisture: if it is too wet, stop watering completely for two weeks. If after this the plant does not recover, replant it into new and moderately moist soil.
2. Feed the plant: maybe you haven't deposited for too long nutrients into the soil, and your flower simply does not have enough microelements.
3. Check the plant for pests: To do this, it is enough to inspect the soil and above-ground parts. If insects are found, they must be destroyed with special chemicals.
4. Inspect root system: To do this, you need to carefully remove the plant from the pot and check whether the roots have rotted. If such areas are noticed, they should be trimmed, the sections should be treated with crushed coal, and the plant itself should be transplanted into a new pot with fresh soil.

Figure 4. Proper care at home

It is important to remember that ficus should not be watered or fed too intensively. It is also advisable to decide in advance on its location: the plant reacts negatively to a change in environment.

Houseplants at home They grow well if they receive everything they need - light, water, warmth, humidity and nutrients. The conditions for keeping it at home largely depend on the origin of the chosen plant; for example, tropical crops require warmth, high air and soil humidity, while cacti, on the contrary, are accustomed to bright sunlight and drought.

When growing houseplants in pots you must follow individual rules for caring for each species, which are based on creating the most similar conditions for a given plant to its natural environment. Violation of this harmony leads to diseases of the flower planted in the pot.

The well-being of a houseplant is always reflected in the appearance of the leaves., they turn yellow, blacken, curl, wither, dry out, fall off, various spots and dots appear on them. Based on these external manifestations, you can make a diagnosis and identify errors in care, whether the flower has enough light and nutrition, whether watering is carried out correctly, whether the room temperature and air humidity are comfortable.

If you correctly determine the reason why house plant feels discomfort and loses decorative look Having eliminated it, the plant will recover and will again decorate your home with flowers and greenery. If you ignore the signals that the leaves give, the plant in the pot will continue to wither and eventually die.

Most often, indoor plants experience the following ailments, which are reflected on the leaves:

Most leaves wither herbaceous plants when the soil dries out. Plants with tough, leathery foliage are resistant to wilting, but respond to lack of watering with massive yellowing and leaf drop.

Each plant requires its own watering rate. You can’t overwater a flower in a pot, but you shouldn’t wait until the soil in the pot dries out completely and the leaves wither. Moisture-loving crops are watered frequently and abundantly. If the soil in the pot dries out quickly and the plant withers, then you need to transplant it into a larger pot with moisture-retaining soil.

If the leaves wither and the soil in the pot is damp , which means you flooded the flower and its roots rotted. When moisture lingers in the ground for a long time, the roots are deprived of air, the earth turns sour, and putrefactive bacteria take hold. A flooded plant can only be saved by urgent replanting, with a complete replacement of the soil, removal of rotten roots and sprinkling of charcoal on the wounds, and further adherence to the watering regime.

Leaves may wilt due to heat , especially if the sun shines on the plant at noon. High temperature increases the evaporation of moisture from the leaf plates, you need to remove the plant from sunny place and spray.

Wilting foliage means the plant is stressed, and this affects his growth and health. Try not to allow stressful conditions to arise for your flower, then it will bloom and develop without stopping.

The tips of the leaves of indoor plants dry out for one reason - low air humidity. Most often, the tips of leaves dry out in tropical crops - palms, ferns, syngonium, chlorophytum and other species. Mass drying of leaves at the tips and along the edges of the plates begins with the beginning of the heating season, when air humidity drops to a critical plant level of 30%, and leaf health requires from 60 to 80%. The problem is solved by installing humidifiers, water containers next to the pots and daily spraying. Hot radiators should be located as far as possible from plants.

Plant leaves turn black due to several reasons . Dark brown dry spots on the tips and edges of the spathiphyllum; they gradually enlarge, crack, fall out, and part of the leaf blade is lost. High temperatures and insufficient watering accelerate the growth process dark spots on the leaves. The solution is to use humidifiers and adjust the watering regime.

It happens that the roots of a plant in a pot are so dry that regular watering cannot help them. In overdried plants, the soil in the pot lags behind the walls. To saturate all the roots of the plant with moisture, even small ones that are located on the border, you need to place the pot in a bucket of water and wait 10-15 minutes until the earthen ball is completely saturated with moisture.

Brown spots and dots on leaves will appear on different places leaves if you spray a plant illuminated by the sun. Droplets of water enhance the impact of sunlight, like lenses, and they burn through the leaf plates, mini-burns appear in the form of small spots. You need to spray indoor plants in the morning or evening with a very fine spray.

Some pests can also cause leaf spot. . They stick to the underside of the leaves and the place where the insects suck the juice from the leaf first turns yellow and then darkens. If many small yellow dots appear on the leaves, check the back of the leaves for the presence of insect pests and traces of their vital activity.

Blackening of entire leaves may occur due to their decay, while the plant tissue becomes soft, jelly-like, this often occurs in plants with delicate fleshy leaves - violets, begonias, balsams. Leaves rot more often due to excessive watering, moisture accumulated at the base of the petiole, from spraying or hypothermia.

In winter, cold air flows from the open window , once under it, the plant quickly cools. Due to a sharp change in temperature, the leaves curl, they may completely or partially turn black on top, this is tissue that has died from the cold or frostbite. The same consequence occurs in plants located close to the window glass. Protect indoor plants from drafts; even a couple of minutes under a cold air stream can be detrimental to any house flower.

The leaves curl, their edges turn inward - this is a sign of a lack of heat, since a plant, as a living being, tells us that it is cold. The leaves can curl into a tube due to a draft, even not a very strong one.

Leaves turn yellow and fall off on plants, usually for natural reasons. . This is how old leaves gradually die off, starting from the bottom of the stem or from the edge of the leaf rosette. Dying of older leaves may occur more quickly in the fall. Tree plants prone to autumn leaf fall, at this time even the conditions in the room change - the duration of illumination decreases, as the days become shorter, and air humidity decreases. For example, Ficus Benjamin annually drops up to 10-20 % leaves, this is natural leaf fall, but which can be reduced by placing the ficus on a sunny windowsill and regularly spraying the greens.

If young leaves at the top of the stem turn yellow , which means there are mistakes in care. When the leaves retain their shape and elasticity, but change their color from bright green to yellow The soil may not have enough potassium or iron, causing a disease called chlorosis. Flowers that prefer acidic soil are susceptible to chlorosis - gardenia, azalea, lemon, clerodendrum, hydrangea. These plants love to be watered with acidified water; they require feeding with these elements from time to time.

Indoor plants that require high-quality soil of a certain acidity often suffer and their leaves turn yellow if the soil in the pot is alkalized with calcium salts when watered with hard tap water. Yellowing of the leaves is observed in plants that are watered with tap water, it contains a lot of chlorine, it poisons the green inhabitants of the pots. Always leave the water for two days to water the plants, during which time the chlorine will evaporate from it, the salts will settle to the bottom, and the water will become room temperature, pleasant for the plants.

Many problems with indoor plants are easier to prevent than to fix. And this rule especially applies to care: an individual approach to indoor pets, careful adherence to the regime of watering and fertilizing, control of the degree of drying of the substrate guarantees the plants preservation of both health and attractiveness. The loss of leaves by indoor plants, even if it is partial, is a problem after which the attractive appearance is not restored as quickly as we would like. Most often it is associated with improper watering, although in some cases other factors also cause this problem.

Leaf loss from indoor plants varies

Indoor plants dropping leaves is a common and serious problem. Along with dry tips, loss of color and spots on leaves, this has the greatest impact on the attractiveness of the plant. But unlike other problems, it can sometimes be solved quite simply, especially if you don’t hesitate. Of course, with significant baldness, the production of new leaves and the growth of the old crown sometimes requires a very long period. But the fight against this itself is not so difficult.

Most often, gardeners encounter this phenomenon during the winter. The discrepancy between typical room conditions and the parameters required by the plant, a sharp reduction in light, drafts, and the need to adjust the frequency of watering only increase the risk of leaf falling (as well as the appearance of any other problem). But you can encounter this phenomenon at other times of the year, even on plants that look like they are actively growing.

Typically, leaf fall is considered a one-type problem, but in fact it can be very different. Depending on the accompanying phenomena, the following varieties of this phenomenon are distinguished:

• rapid or massive loss of leaves without other changes;
• dropping lower leaves;
• leaves falling off after curling;
• falling leaves after yellowing;
• partial shedding of foliage in newly acquired plants.

Oddly enough, all these types of abscission are caused by for various reasons and require a different approach to care correction. Factors that cause leaf loss depend on the frequency of watering, the location, the age of the plant, and even the form of its growth.

Rapid leaf fall in indoor plants

The rapid shedding of foliage, including young leaves, and sudden exposure of the crown are typical only for deciduous shrubs and trees (figs, pomegranates, etc.) and are rare in indoor cultivation. The leaves of both tuberous and bulbous plants (amaryllis, gloxinia, begonia, zephyranthes, oxalis, etc.) fall off when entering the dormant stage, but this is rather an exception to the rule. If your plant suddenly sheds its leaves and does not belong to the listed categories, then there can be only one reason - the plant has experienced a strong traumatic factor, a sharp change in conditions. For such exposure it is necessary to really radically violate the rules of care. Factors that caused this decline may include:

• rearrangement shade-loving plant under straight lines sun rays;
• temperature difference of 10 degrees or more (in any direction);
• draft with icy or frosty wind;
• complete drying of the substrate in woody plants when installed in a hot place.

Falling leaves of indoor plants after folding

This type of abscission is caused by a systemic violation of conditions comfortable for the plant in the direction of an undesirable decrease in temperature and increase in humidity. He is called:

• using too much water, which stagnates in the substrate;
• a decrease in air temperature compared to the recommended one (not short-term);
• drafts for plants that are very afraid of them.

Falling leaves of indoor plants after yellowing

For indoor shrubs and fast-growing crops, gradual yellowing and loss of older leaves is natural, occurs as they grow, and is not considered a sign of serious health problems. But the massive yellowing of leaves, followed by the same massive dropping of them, indicates a serious lapse in care. The following factors cause this type of abscission:

• waterlogging of the soil for non-moisture-loving species;
• placement in a constant cold draft for sensitive plants.

Drying and falling of the lower leaves of indoor plants

This process is not natural. It is caused by insufficient conditions, as a result of which the plant is forced to get rid of the lowest leaves in order to preserve the rest. This phenomenon is caused by factors opposite to waterlogging and hypothermia:

• content in heat, in temperatures exceeding the recommended by more than 5 degrees;
• very poor lighting for light-loving plants;
• constant drying out of the soil in moisture-loving species.

Loss of leaves in newly purchased indoor plants

As a rule, partial fall of foliage in this case is always associated with a sharp change in conditions due to moving. The plants did not undergo gradual adaptation and perceived the lighting or temperatures as “shock” in the new place. If the shedding of leaves is not massive, then there is nothing terrible about it. Over time, the plant will recover and get used to it. But it is better to ask carefully when purchasing about the conditions in which the crops grew and provide at least an intermediate option with a soft transition so as not to lose a single leaf.

The first thing to analyze is watering

In most cases, the dropping of leaves of a houseplant is associated with improper watering. And it is by analyzing what mistakes you might have made that you need to begin searching for both the source of the problem and its solution. Regardless of whether there are other factors that could have caused the leaf loss process, always consider this factor carefully.

Houseplants are watered not as conveniently, and especially not when they want, and not even at a certain “correct” interval, but as they need it. To find the correct schedule of procedures for each specific plant, you need to study the recommendations and draw up a table. You can attach tags or short notes to plants that are different from most (such as colored tags). Most indoor plants have similar requirements, and you can develop your own watering system without spending extra time. But general guidelines do not replace an individual approach: before pouring water on the substrate, check how dry it is.

Perhaps, due to a combination of temperature and lighting at a particular time of year, the soil dried out more slowly or quickly, and accordingly the plant needed a different frequency of treatments. During the dormant period, the frequency of watering for all plants is adjusted in accordance with the rate of drying of the substrate and their need for the dormant stage. But even for flowering plants Watering is still reduced. Check the information for your specific plant and compare whether your watering meets its needs. Any deviations in any direction are a serious factor in leaf loss.

Other factors that can cause houseplants to drop leaves:

• incorrect wintering temperature;
• lack of lighting correction in winter;
• dry air;
• depleted soil;
• late or unnecessary plant replanting;
• replanting with soil replacement instead of transshipment;
• poor or excessive feeding;
• incorrect water characteristics;
• type of substrate that does not correspond to the type of plant;
• exposure to heating devices;
• the appearance of pests on the plant (including soil-borne ones);
• accumulation of dust on the leaves and dirt around the plant;
• lighting for plants that can only grow in natural light.

How to stop houseplants losing leaves

The strategy for combating leaf fall directly depends on the cause of this phenomenon. Eliminate the unfavorable factor - and your plant will again delight you only with growing, and not falling leaves. So, in drafts, you need to rearrange the crop, if the lighting is too bright, install screens, adjust the frequency of watering according to the rate at which the substrate dries out, change the room if the temperature is incorrect, etc.

If the loss of houseplant leaves is caused by pests or diseases, the strategy is completely different.:

• the plant must be immediately isolated from the rest of the collection;
• if possible (if the leaves are not pubescent and we are talking about pests), carry out mechanical processing– washing with soapy water, showering;
• treat the plant with biological products;
• if the problem is advanced, use insecticides or fungicides, the action of which is aimed at specific pests or fungi, and if affected by soil pests, carry out an emergency transplant.

To solve the problem, the probable causes of this phenomenon are determined, there are several of them:

1. Unsuccessful transplant;
2. Improper watering;
3. Insufficient air humidity;
4. Lack of light;
5. Excess or lack of fertilizers;
6. Drafts;
7. Sunburn;
8. Pests;
9. Diseases.

All these reasons can lead to yellowing and falling leaves of a domestic rose.

Reason 1. Unsuccessful transplant

After purchase, you should not immediately replant an indoor rose - it needs time to adapt. The air in a living room is drier than in a store, and in winter time heating batteries are also included.

Reason 2. Improper watering

Yellowing in the middle of the leaf, along the veins of a domestic rose, often occurs due to drying out or waterlogging of the soil. Overdried soil, the appearance of a crust with cracks on top layer — a clear sign lack of moisture.

• When the soil becomes waterlogged, watering is temporarily stopped and replaced by spraying. It is necessary to water the plant when the soil dries to a depth of 1-2 cm. Settled water is used for watering.
• The frequency of moisturizing depends on the time of year. In summer, roses require regular, abundant watering.
• Watering is gradually reduced after the end of flowering, bringing it to 1 time every 7 days during the winter months.
• In spring, watering is increased after a sufficient number of leaves have bloomed.

Reason 3. Insufficient air humidity

Miniature house roses need high humidity air.

Reason 4. Rose leaves may turn yellow due to lack of light

For comfortable growth and successful flowering indoor roses need to be in the sun for 5–6 hours. A west or southwest window is suitable for this. On southern windows, due to excess direct sunlight, rose buds quickly bloom and also quickly wither. North windows are not suitable due to lack of light.

• It is worth talking about problems with lighting when the foliage turns yellow on the shaded side.
• For uniform formation of the crown, the bush is turned to the light in different directions.
• In the spring-summer period, it is advisable to take the pot with a rose out onto the loggia or balcony, where the amount of light is sufficient for the harmonious growth of the flower.
• Even better, plant a flower in open ground or dig into the ground along with the pot. There it can easily withstand even exposure to direct sunlight.

Reason 5. Excess or lack of fertilizers

Yellowing of leaves indoor rose can be caused by excess or lack of fertilizers. The appearance of the foliage depends on the following elements.

Iron

Plants that receive sufficient iron levels grow strong and disease-resistant. Iron deficiency causes a disease called chlorosis. The leaves curl at the edges, turn yellow, and become smaller. First of all, young leaves suffer from iron deficiency, then yellowness spreads to adult leaves. Chlorosis is accompanied by slow growth of the domestic rose and loss of green mass. Iron deficiency occurs more often in alkaline soils.

What to do: To restore acidity, use a fertilizer that acidifies the soil, for example, organic. For neutral acidity, use foliar feeding drugs Ferovit, Ferrilen.

Nitrogen

Roses experience nitrogen deficiency more often in the spring. Lack of nitrogen leads to paleness and yellowing of the foliage. The color change starts from the lower leaves and gradually moves upward. Meanwhile lower leaves fall off.

What to do: Nitrogen deficiency can be replenished by fertilizing with urea or universal fertilizer.

Manganese

With a lack of manganese, yellowing begins with old leaves. Yellowness appears between the veins, moving from the edge to the center of the leaf. A green border remains around the veins. This happens when an indoor rose is planted in alkaline soil. Either a lot of lime was added when planting the bush.

What to do: The situation will be corrected by introducing a solution of manganese sulfate under the plant, deoxidizing the soil.

Magnesium

Magnesium deficiency occurs more often in plants growing on acidic soils. The deficiency of the element is reflected first on adult leaves, and then on young ones, in the form of discolored spots. Reddish-yellow spots appear between the veins. The edges of the leaves remain green, but leaf fall on the windowsill is inevitable.

What to do: the magnesium content is restored by adding magnesium sulfate and ash. If there is an excess of magnesium, potassium cannot be absorbed by plant roots. When applying fertilizers, adhere to the recommended dosage.

Reason 6. Rose leaves may turn yellow and fall off due to drafts

Drafts - the enemies of house plants - provoke yellowing and shedding of leaves.
If drafts are inevitable, then you can make paper or plastic screen to the height of culture. It will protect the flower from drafts.

Reason 7. Sunburn of rose leaves

Sunburn leaves brown and yellow spots. Damaged foliage dries out and falls off. Burns occur from excess direct sunlight or from spraying cold water in the scorching sun.

You can avoid burns by moving the pot to a southwest or southeast window.

Reason 8. Pests of indoor plants

Pests on homemade rose also contribute to the appearance of yellow leaves and worsen the condition of the plant as a whole.

Spider mite

The insect lives on the underside of the leaf, spreading a web along the shoots. The foliage turns yellow, dries, young shoots die. Reason for appearance spider mite- excessively dry and hot air in the room, dense accumulation of plants.

Fighting methods:

• It is necessary to lower the room temperature
• Increase air humidity
• Wash the rose bush from cobwebs with a solution of laundry soap
• Treat with Fitoverm or Vermitek solution. Treatment is carried out at least 2 times, with an interval of 10 days.
• It is advisable to isolate the diseased plant from other plantings.
• The soil is also treated with insecticides.
• Prevention against mites - frequent spraying of roses.

The adult and larvae of the pest live on the underside of the leaf blade. As a result of the life activity of the rose leafhopper, pale spots appear on the foliage. The leaves turn yellow, curl and fall off, and the development of the rose slows down. The reproduction of the rose leafhopper is promoted by heat and dry air.

Fighting methods:

• On initial stage Wash the plant with soapy water on all sides.
• In case of severe damage, the rose is treated with solutions of insecticides, for example Aktara or Fitoverma.
• To enhance the effect of the drugs, add a tablespoon of alcohol per liter of solution.

Thrips

When affected by microscopic thrips, the leaves become yellowish and have a silvery coating, and are deformed. Infection is favored by elevated temperatures and dry air.

Thrips on rose leaves.

Fighting methods:

• It is necessary to ensure high air humidity
• Before spraying a plant with an insecticide solution, isolate it from other plants.
• The soil and the place where the flower stood are also treated.

Reason 9. Indoor rose diseases

Not favorable conditions And improper care provoke diseases. Regular inspection of plants will help prevent their occurrence.

Powdery mildew

The reason for this fungal disease How powdery mildew, is too wet soil, lack of fresh air, excess fertilizer or heat.

Signs of the disease include yellowing, curling and falling leaves.

Fighting methods:

• Be sure to remove diseased shoots, leaves, buds
• Treat the entire bush with a fungicide solution.

Black spot

Black spot - infectious disease. Signs of the disease: yellowing of the green mass, formation of dark spots with jagged edges. A diseased rose does not tolerate winter well, grows more slowly and blooms little.

Fighting methods:

• Any systemic fungicide will help defeat the disease.

Knowing why indoor rose leaves turn yellow and fall off, you can prevent many problems.

A few more necessary rules for caring for mini roses:

• Flowers need access to fresh air.
• From October to February, indoor roses need rest.
• After flowering ends, reduce watering.
• Shoots are shortened to 10 centimeters.
• Roses are transferred to a cool room.
• In spring, rested bushes will begin to actively produce new shoots and form buds.
• Roses are pruned twice a year: before wintering, during flowering.
• When pruning, the outer bud is left. A bud that is directed inside the bush does not form it correctly.
• When shortening shoots in the fall, 4-5 buds are left for each strong shoot, and 2 buds for each weak shoot.
• At summer pruning delete wilted flowers, yellow leaves.

To activate protective functions indoor roses, to increase immunity, plants should be periodically treated with biostimulants: Epin, Zircon.

As you know, each type of plant needs an individual approach. In order for them to feel good and delight us with their lush green crowns, fragrant and bright flowers, it is necessary to create favorable conditions for them. In addition to proper care of indoor plants, it is also necessary special microclimate. If these conditions are violated, they get sick and die.

How plants shed leaves

Each type of plant has its own preferences in soil dryness or moisture, as well as its composition. It is also necessary to observe the watering regime and do not forget to feed them.

There is no need to forget about air humidity - this is one of the important parameters.

Some plants love spraying from a spray bottle, others are indifferent to them, and others don’t like them at all and can even get sick.

When indoor flower loses leaves, it not only loses its attractiveness, but this also indicates some kind of problem. Such a plant needs to be given attention and treated. And after some time it will again restore its previous appearance.

Most often, this the problem appears due to incorrect watering schedule. Sometimes it is enough to adjust the watering and the plant will return to normal. But other factors can also cause leaf fall.

Indoor flowers losing their leaves is accompanied by problems such as loss of color, dry tips, and spots on the leaves. And all this, of course, spoils appearance plants. Timely help will help prevent severe baldness. But even after solving the problem, it will take time for fouling and restoration of its previous appearance.

This problem is most typical for the winter season. Temperature change, reduction of sunlight, changing the watering regime, all these factors create stress for them and cause leaf loss. Sometimes this is even a natural process for some indoor flowers.

But it happens that at other times of the year such a problem may arise. And this is a signal about other reasons.

Calathea leaves dry and curl: first aid for the plant

Types of abscission

Falling leaves of domestic flowers, like reasons for this phenomenon, may be different. The following types of leaf fall can be distinguished:

1. Yellowed leaves are falling.
2. Leaves fall off after curling.
3. Fall off lower leaves.
4. The leaves partially fall off after purchase.
5. The plant sheds a lot of healthy foliage.

Each variety has its own reason, and, therefore, requires a different approach to the problem. The reason may be not only in care or watering, but also in the location, age and type of plant. Various flowers The problem can also manifest itself in different ways.

Seasonal yellowing of foliage

Seasonal yellowing of foliage- a characteristic phenomenon for some indoor plants. And the subsequent loss of foliage is a natural process; it occurs as the plant grows and develops and is not considered a disease.

However, if they fall simultaneously in large quantities, then there are clearly some violations in the care of the flower. The reasons may be the following:

• The plant is in a constant draft and cannot tolerate it;
• A lot of moisture in the soil (relevant for flowers that prefer dry or slightly moist soil).

Leaves fall off after curling

The leaves curl and fall off when unfavorable conditions content when the air temperature becomes lower and the humidity higher than the plant prefers. These conditions may cause:

• Drafts and cold temperatures.
• Excessive watering, causing stagnation of water in the soil (at low temperatures, it is necessary to reduce the frequency of watering).

The lower leaves are falling

Each flower requires certain conditions to grow and develop. But if the plant lacks something, then it begins to shed its lower leaves so that there are enough resources for the remaining younger leaves. The reasons causing this unnatural process may be the following:

• Insufficient watering (important for moisture-loving flowers).
• Lack of light.
• Air temperature constantly exceeding recommended parameters.

Causes of yellowing leaves in plants

Leaves partially fall off after purchase

When a plant moves to a new location, it experiences stress. He needs to get used to new conditions and adapt to them. It is during times of stress that it sheds some leaves. After a short period of time, the plant will get used to it and recover. But at this moment it is recommended to create the most favorable conditions for the new flower, close to its natural habitat. In this case, you can even do without losses.

The plant sheds a lot of healthy foliage

There are plant species that are characterized by rapid shedding of leaves when going into hibernation. These are woody and deciduous, as well as tuberous and bulbous varieties. For them this phenomenon is considered normal.

But for other species, this process indicates severe stress for the plant, which has experienced a sharp change in conditions for the worse, as if the plant had been injured. To bring a flower to bare crown, you need to “try hard”.

Why there is a sudden shedding of foliage, the reasons may be the following:

• Draft along with frosty wind.
• Strong temperature changes in any direction.
• Exposure to direct sunlight (relevant for shade-loving plants).
• Drying of the soil when placed in a sunny place.

Determining the causes

To solve a problem, you first need to find its source. Most often, the cause may be non-compliance with the watering regime. It is also worth paying attention to other factors. Each plant has its own interval and volume of watering; it is necessary to monitor soil moisture. In order to find the desired interval, you need to follow the recommendations and also observe your home flower. Over time, you can develop the right system watering for all flowers in the house, taking them into account individual requirements. IN different times Plants have different preferences every year. When entering the dormant period, the frequency of watering must be reduced. If there are deviations in the watering regime, the plant gets sick.
