Ficus diseases with photographs and their treatment

Ficus diseases appear if the conditions of maintenance and care at home are violated. The growth of home ficus does not require complex care. In a modern apartment he feels great, but is still susceptible to many diseases. It is important to correctly identify the problem in order to choose the appropriate treatment method. Ficus diseases appear due to lack of prevention and unfavorable external factors (extreme heat, excess humidity). Often a flower becomes infected from nearby plants.

Why are ficus diseases dangerous?

Diseases of Ficus Benjamin can significantly damage the plant, and in some cases even destroy it. What should you do if your ficus leaves turn red or have white spots, mites, aphids and white or red dots? You need to act immediately. If you do not purchase special medicinal products in time and do not rid the sick houseplant of pests and diseases, as well as white lumps, it may simply die.

In addition, what is dangerous about an invasion of parasites is that it increases the risk of a similar problem occurring in your other evergreens. Study the most common diseases of ficus, determine the source of the outbreak of the flower disease, and then proceed to full treatment.

Fungal and other diseases

If the leaves begin to fall in the fall, there is no reason to worry. This is completely normal. However, there are other reasons that negatively affect the growth of ficus.

Root rot is caused in two ways: poorly drained soil or too frequent watering. Any of these situations will cause the roots to begin to soften and rot. The problem can be prevented very simply by adjusting watering control and organizing high-quality drainage.
Phomopsis canker is caused by pruning with a non-sterile instrument. This fungal disease enters the plant through cuts. The easiest way to combat this is to completely cut off the affected branch, since there are no chemical treatments for this disease on the market.
Ficus plants sometimes attract fungal pathogens that cause crown rot or stem rot . It attacks the plant from the ground line, causing the crown to rot and the leaves to yellow, wither and even die. High humidity contributes to the appearance of a white coating on the soil and stems. Brown spots and sometimes gray mold appear. Spraying healthy foliage with a mancozeb-based fungicide will help.

Most bacterial diseases cannot be treated, so the plant is completely destroyed. Good care can prevent infection. A simple set of fertilizers, applied on time and in the required quantity, helps to revive a plant if it is not growing well.

Causes of the disease

Sometimes ficus trees can develop various kinds of diseases. They usually occur due to improper or negligent care. Pests emerge from contaminated soil, quickly attacking the roots and destroying the plant. Or the flower may freeze and die from fungi and other related infections.

The main causes of ficus diseases:

temperature imbalance;
excess or deficiency of air humidity;
untimely or frequent watering;
lack or oversaturation of essential microelements.

Ficus is never placed near a heating radiator. If heating devices are located nearby, then a moistened cloth is placed on them and on the windowsill for protection, and the surface of the flower is often sprayed with small drops. If the humidity, on the contrary, is high, then it is advisable to wait until the soil dries 2-3 cm, and then continue watering.

You should beware of extreme heat and excessively dry air, strong drafts and gusts of wind. You cannot spray ficus and then place it in the sun - you can cause the leaves to burn.

If the grower takes diligent care of the plant, then the risk of disease is minimized. However, sometimes cuttings and young stems may have hidden diseases that are not noticeable at first glance. Infections and parasites (for example, nematodes) are introduced from the soil. Ficus often dies from them.

It is recommended to fertilize ficus in the warm season - once every two weeks. With the onset of autumn, they feed less often; in winter there is no need to touch the flower. Nourish the soil according to the instructions on the package so as not to overfeed. The leaves also react to excess feeding - dots and specks appear on them.

If rot appears at the base of the root, the leaves wither and curl, the culprit is most likely constant flooding. If the ficus stops growing, the soil is depleted and mineral resources are running out.

What can a ficus suffer from? How to identify a disease by the leaves of a plant and cure it?

Powdery mildew is considered one of the most common diseases of ficus. This disease is easily recognized by white spots on the leaves of the flower, which can be wiped off with your hand.

Powdery mildew on ficus

The cause of this disease can be an excess of direct sunlight, too high a room temperature, excess humidity, as well as damage to leaves by insects. Treatment is best done at the initial stage, using a soap solution and a sponge. If the leaves are already too heavily stained, they must be removed and the plant sprayed with a fungicide.

Another most common disease of ficus and other indoor plants is anthracnose or rust. This disease is accompanied by the appearance of yellow to dark brown spots. Later, the leaves become covered with ulcers, and the ficus begins to shed them, as a result of which it can become completely bare. You can cure flowers affected by rust using a fungicide.

Ficus anthracnose

Ficus trees can also be susceptible to diseases caused by mold, such as botrytis or gray mold. These diseases are characterized by the appearance of a dark coating on the leaves of the plant, which, when shaken, flies through the air. Over time, the leaves of the flower may completely darken and fall off. The cause of this disease is high humidity and high temperature in the room in which the flowers are located. The disease can be cured by removing damaged areas of the plant and treating it with a fungicide and insecticide.

Botrytis (grey mold) on ficus

Excessive watering of plants can cause a disease called root rot. It is difficult to notice, since it occurs in the ground and is only accompanied by withering of the plant. The root system ceases to function properly, and the ficus dies over time. Unfortunately, it is impossible to cure this disease; the plant must be thrown away along with the pot.

If black spots similar to soot appear on the leaves of a plant, then it has suffered from a disease called sooty fungus. It is impossible to notice such a plaque, and the plant begins to emit a rotten smell. In this case, it is necessary to wipe the leaves with a sponge and soapy water and treat the plant with a fungicide.

Dampness and excessive humidification of indoor air can cause cercospora disease. It is accompanied by the appearance of small brown or black spots on the lower part of the leaves of the plant. Then these spots increase, the leaves turn yellow and fall off; If the disease is neglected, the flowers may even die. Cercospora blight can be cured using a fungicide and other antifungal drugs.

Cercospora blight on ficus

Almost all of these diseases appear due to damage to ficus by fungi, which easily spread and take root on plants due to poor care. To prevent fungal infections, it is necessary to create comfortable living conditions for flowers, and to ensure timely detection of ailments, ensure regular inspection of plant leaves. In addition to improper care, indoor plants have other enemies - these are all kinds of insect pests that develop in the spores of a flower and feed on its juice; each of them is worth talking about separately.

Leaf diseases

Why do ficus leaves fall off? There may be several reasons why the plant is sick. Among the most common diseases of the leaf blade of the home ficus, the following are worth highlighting.

If the leaves begin to wither and curl inward, this is the first sign that the ficus is sick. The appearance will clearly show the reason why the infection occurred. Leaf blades may look like this.

Brown. Demonstrate a state of stress as a result of transplantation.
With reddish spots. Several reasons: in most cases - sunburn, as well as increased watering and drafts.
With brown spots. Insufficient watering and dry air, exposure to heat, excess fertilizer in the soil. Plaques of this color along the leaf veins indicate infection by parasites.
Covered with gray coating, cobwebs and white spots. Mites, thrips larvae, beginning gray rot.
Yellow edges with small white dots. Excessive watering, excessive humidity.

The leaves are turning yellow

As a rule, this problem occurs in winter. Heating devices are actively working in the apartment, and hot air flows are often directed at indoor plants. For a sick ficus, this factor will be disastrous. The leaves begin to turn yellow, wither and gradually fall off. When a flower sheds its leaves en masse, it stops growing and may die.

The best solution for you is to move the flowerpot with the evergreen specimen to another, much more suitable place. However, be careful when looking for a new corner to place your ficus pot. If you disturb it too often, the yellowing of the foliage may begin again, but this time the ficus will get sick due to the stressful situation you created.

Another reason for yellowing leaves is burns caused by direct sunlight.

How to save a plant from this?

In summer, the flower should not be exposed to direct sunlight for a long time.
In winter, it is better to relocate it to places far from the batteries.

To humidify the air, use a container of water near the plant.

Leaves fall off or become small

Such ficus diseases also pose a serious danger to the plant, so they must be treated as quickly as possible. The diseased plant gradually withers, and the reason for this is a lack of nutrients in the soil. The situation can be corrected. To do this, it is necessary to replant the plant, completely replacing the soil composition;

The tips of the leaves turn yellow, yellow spots appear

This problem indicates an excess of moisture in the soil. Do not forget that ficus loves moisture, but watering should be moderate. Be sure to let the soil dry before irrigating the substrate again. For an indoor flower, a lack of moisture will be much less destructive than its excess.

It is urgent to dry the soil and review the watering rules. Ficus does not tolerate stagnation of water in the pan. Drafts and, in general, any sudden change of environment are harmful to him.

Ficus sheds leaves from below

This reason is considered natural - each ficus leaf blade develops within three years, and then ages and falls off. However, the trunk cannot be completely exposed, since in this case it will be very difficult to save it. If you observe the fulfillment of unsuccessful forecasts, it’s time to replant the flower or add complex mineral fertilizers to the soil;

Why does ficus shed its leaves completely?

The main reason for dropping leaves is overdried soil or watering with poor quality water. If a ficus sheds its leaves due to a lack of water, then its root system is also not in the best condition, because it is directly related to nutrition and water balance. In this case, you need to water it generously and subsequently monitor the quality and frequency of watering.

Ficus tree varieties tend to fall off the leaves of the lower part of the trunk , but this is not a disease. In general, the bush itself never becomes bare, but on the contrary produces more and more new leaves. Ficus leaves may fall off in other cases. The flower is either affected by an infection or by some pest. In such cases, treatment with special preparations is necessary.

Pests on ficus leaves

As a result, the leaf blade dies sooner or later if treatment is not taken. You can get rid of pests with the help of special insecticidal preparations, which you need to buy in the store.

Ficus doesn't grow

The following external symptom can also indicate a problem with the soil: the leaves begin to grow smaller and smaller and eventually the ficus stops growing altogether. Most often this occurs due to soil depletion . When the moment comes that the soil is depleted of all useful resources, the recently blossomed ficus leaves begin to gradually become smaller in mineral components, and their predecessors turn yellow, wither and fall off.

To return the plant to normal functioning, it is necessary to replant it or replace the soil. The substrate must be saturated with the necessary mineral complex and vitamins. Stores now sell soil specially prepared for ficus.

Rules for the care and cultivation of rubber ficus

To obtain a strong, strong tree, you do not need to spend a lot of money and labor; it is enough to follow the rules of care and provide the tree with optimal conditions.

Temperature

The optimal temperature is between + 20 and +25 degrees in summer, and in winter not lower than +15 degrees.

Priming

Loves fertile, loose soils. You can make such soil yourself by mixing turf soil, coarse river sand and humus in equal proportions, or by adding sand and humus to a purchased soil mixture. The tree loves transplants, as the roots grow quickly and require more space. Therefore, every year in spring or early summer it is transplanted into a larger container using a transshipment method.

Fertilizing is carried out from the beginning of spring to mid-autumn 2 times a month, alternating liquid organic and mineral fertilizers.

Lighting

When growing indoor ficus, it is necessary to provide it with adequate lighting: bright, but diffused and sometimes shaded light would be ideal. Due to lack of light, the lower foliage turns yellow and falls off. In winter, when there is insufficient lighting, reduce the number of waterings and lower the room temperature, preferably to +17 +18 degrees.

Cold drafts may cause dark brown spots to appear on ficus leaves; it cannot withstand hypothermia.

Watering

Constant but moderate is necessary. After watering, you need to wait until the soil dries 1-2 cm. It also responds well to spraying with water at room temperature, not lower than 15 degrees, especially in the cold season with constant battery operation.

When the tree becomes dirty, wipe it with a damp sponge from the outside and inside.

Trimming

The plant requires moderate pruning to form a crown. As it grows, the lower leaves fall off and a bare trunk remains. Pruning is carried out at the end of winter and not only the crown is cut, but also 4-6 internodes in the upper part of the tree.

Infectious diseases

If various pests appear on the leaves of Ficus Benjamin, you can fight them quite effectively, especially if you noticed the problem at an early stage. But if you are faced with infectious diseases, it is much more difficult to cure the plant from them.

The first signs are difficult to notice, and when a flower is seriously ill, even the most effective methods do not always give the desired result. To defeat infectious diseases of ficus plants, it is necessary to take a closer look at what plant ailments a domestic gardener may encounter, and what to do in this case.

Symptoms of diseases

Ficus turns black

The leaves are covered with small black dots and specks, mainly on the inside.

This is how Cercospora fungal infection manifests itself. Subsequently, the leaves may change color, lose turgor and fall off.

How to revive a ficus?

To save the plant, it is necessary to remove all the affected parts and treat the plant and soil with fungicides - Fundazol, Kurzat, Oksikhom. The entire surface of the leaf turns black, then it falls off.

An oversight in care is to blame - the ficus suffers from excessive watering and constant soil moisture. In this case, you should change the humidification mode, reducing it by at least 2 times.

It is recommended to moisten the soil no more than twice a week.

Darkening edges indicate burns from direct sunlight.

Another reason is that the ficus is hot. It stands close to heating appliances or on a windowsill under the scorching sun.

It is enough to move the pot with the plant to the western or eastern window and remove it from heat sources.

The appearance of asymmetrical, varied black spots indicates improper soil or excess nutrients.

Help: the optimal composition of the soil is sand, leaf soil and peat in equal quantities.

The ficus "Benjamina" should be replanted in a fresh substrate and the addition of mineral complexes should be reduced.

As you can see, proper care of the Benjamin ficus is very important for the plant, so we have prepared several useful materials about the secrets of its propagation and the peculiarities of growing it at home.

Fungal diseases

Fungal diseases of ficus are considered the most dangerous for the plant. If pests of Ficus Benjamin are removed using high-quality insecticides, in some cases a green specimen affected by a fungal disease cannot be saved even by an experienced gardener. What specific ficus diseases fall into this category is worth studying carefully.

Anthracnose or rust

Along the edges of the leaf, rust-colored spots with a brownish border are visible. The damaged part dies, forming holes in the leaves. Then they darken and fall off. The infection is caused by a fungus called Colletotrichum orbiculare.

Pests are controlled by spraying the roots and stem with a fungicide. It is also used to treat surfaces with “ulcers” from rust.

Powdery mildew

Causes white plaque-like spots. Occurs in areas of pest damage and fungal infection. Plaque also appears from strong light exposure.

To get rid of powdery mildew, laundry soap alone is not enough. You will also need copper sulfate and soda ash. Prepare a medicinal solution by mixing a teaspoon of soda and two grams of soap in a liter of water. Separately dilute 2-3 grams of copper sulfate. Combine everything together, add another liter of water and spray the affected parts with this mixture.

Botrytis

A gray coating consisting of small spores of the fungus Botryotinia fuckeliana. The spots gradually become darker, then the leaf blades fall off the stem.

Sooty mushroom

The lesion looks like a black coating similar to soot. The reason is an active attack by insects. Their sticky secretions feed fungi that silently multiply on the foliage.

Black plaque indicates a double lesion. Sooty fungus occurs as a result of insects. A concentrated soap solution will prevent the spread of fungus. If the leaves are severely affected, it is better to remove them.

Cercospora

Caused by fungi of the Cercospora family. Visually, the manifestations of the disease look like brown and grayish dots on the underside of the leaf. Then the dots become much larger, and the leaves turn yellow and fall off.

Cercospora and anthracnose require treatment with special antifungal drugs.

Such an infection cannot be started; urgent measures must be taken. The ficus may not survive and dry out completely. Treatment of fungal infections is carried out immediately with special means.

Late blight, pythium or rhizoctonia

Dangerous fungi that cause rotting. It is better to throw out or destroy an infected ficus to keep nearby plants healthy.

Gray rot

Among the diseases of the house ficus, which are the result of the activity of fungal formations on the flower, it is worth highlighting first of all gray rot. The key sign of the disease is blackened leaves, which eventually fall off. As a rule, the disease appears due to excessively high humidity in the room. In the fight against this disease, it is necessary to reduce the frequency of watering and also ventilate the room more often.

If gray rot appears, then it is necessary to immediately remove the infected leaves. The soil at the roots should dry well. This should help revive the plant. It is also recommended to replace the soil and replant the remaining roots in clean soil.

Sooty mushroom

Treatment of black plaque (and this is a key sign of the disease) may be necessary after the plant has been attacked by harmful insects. The initial stage of fighting the disease involves washing the flower with soapy water. Soak a sponge in the liquid and carefully go over each leaf. The stem must also be treated with a fungicide. As a preventative measure, do not overwater the flower in the future. Irrigating the substrate with a solution of manganese will not hurt either. It is advisable to carry out this procedure at least once a month.

Fungi on leaves

Among the fungal formations that mostly appear on leaf blades, it is worth highlighting cercospora, anthracnose, and botrytis. As such diseases develop, black, yellow or brownish spots develop on the leaves. If you don’t fight them, the same result awaits you: the death of the leaf blade.

The disease must be eliminated by removing the affected parts and treating the plant with a fungicide.

For what reasons did brown spots appear on ficus leaves?

Not all gardeners understand why dark spots appear on ficus.

In fact, there are several of them, but they all boil down to one main factor: a houseplant begins to get sick if you have not properly cared for it or created a suboptimal microclimate in the room.

Hence all the diseases, as well as pest infestations. It is worth considering in more detail why spots appear on the ficus leaf plate. The sooner you identify the source of the problem, the more effective the treatment will be.

Overdrying of leaves

It is known that ficus diseases appear due to errors in the process of caring for the flower. The first thing you should pay attention to is the microclimate and lighting in the apartment. The plant loves moisture, but excessively bright light and dry air in the room have a detrimental effect on it.

On hot summer days, it is not advisable to place a flower in a pot on a windowsill so that direct sunlight falls on it. The best option is to move the flowerpot to a place protected from excessively bright light. But be careful: the ficus should not be in the shade.

It’s clear what to do with ficus in the summer, but what to do in winter? At this time, it is also necessary to adhere to certain rules.

For example, since batteries and various heating devices are actively working indoors in winter, hot air flows can often be directed at the plant.

This is very harmful to the flower, so in winter, try to move the flowerpot with ficus away from radiators.

Ficus overflow

Sometimes ficus leaves become covered with dark spots due to excessive moisture in the substrate. In the case of this plant, the lack of water in the ground is less problematic for it than its excess.

That is why it is advisable to let the soil dry out before the next watering.

If you do not reduce the level of soil moisture after brown spots appear on the leaf, the root system of the flower will gradually begin to rot.

Wrong fertilizers

Very often, ficus leaves become covered with a white coating due to improperly applied or chosen nutrient mixtures. Interestingly, even from an excess of minerals in the soil, a plant can stop growing. The thing is that the flower stops absorbing nutritional components at a certain moment if their volume is several times greater than the norm.

In order to avoid such mistakes, take into account the fact that it is recommended to fertilize no more than once every two weeks. In addition, you can prevent the appearance of brown spots on leaves if you choose high-quality fertilizers. They must contain a large amount of nitrogen.

How to determine the source of the problem

If brown spots suddenly appear on the leaves of a ficus, first of all you need to understand what the cause of this disease is. This can be caused not only by excessively bright lighting or excessive watering. Among the factors that adversely affect plant development, it is worth highlighting sudden temperature changes and especially low temperature readings.

Stagnation of water in the pot can also slow down the growth of ficus.

Sometimes gardeners do not notice that the plant has long needed replanting, and after the next irrigation of the substrate, the water passes through the ground too quickly, ending up in the pan.

It does not have time to evaporate, and this is fraught with serious consequences for the rhizome of your evergreen tree. The root system may simply rot, so it is recommended to remove water from the pan soon after irrigating the soil.

If white coating on the leaves or brown dark spots have “attacked” your home ficus, it’s time to start treatment. But in order to correctly determine the source of the problem, carefully inspect the plant and, if necessary, remove dry leaves.

If preventive measures did not help you protect the flower from disease, it is advisable to resort to more serious methods: replanting with replacement of the soil composition, spraying with insecticides (if the flower was susceptible to attack by pests).

How to cure indoor ficus

White spots and white dots, as well as dark coating on ficus leaves, are a serious problem for any gardener. It is necessary to act immediately after detecting at least one such insignificant speck. Of course, experienced specialists, as a rule, recommend buying professional insecticides for flower treatment.

If the disease is at an early stage, it is quite possible that you can cope with the use of home remedies. However, you should not rely on them if the plant is already on the verge of death. The same white spots on the leaves indicate the development of a disease dangerous for the ficus. If this appears, immediately buy professional products.

When a flower suddenly gets sick, becoming covered with white spots, many gardeners do not dare to purchase medicinal drugs. For those who are worried about the condition of the ficus after using chemicals, the optimal solution would be a copper-soap mixture or a fungicide solution.

Wipe the leaves on both sides with this medicine daily until the white or dark spots disappear from the leaves. No matter how hard you try to care for your indoor ficus, it can still get sick, and its leaves can become covered with white dots or plaque. In this case, the sick flower must be immediately treated with effective medications.

Root rot

If a ficus gets sick with root rot, it means that you did not follow the plant’s watering regime at one time. In this case, the root system begins to actively rot, and the stems and leaves wither, gradually losing their brightness and acquiring a grayish color.

Interestingly, if the infection gets into the soil, it may not spread to the flower for some time. But sooner or later this will happen, and then the only correct solution will be to throw the plant and the pot in the trash.

Why do ficus trees get sick?

In general, tree-like species, such as Benjamina, Microcarpa, Binnendijka, are resistant and healthy plants, but they are also susceptible to infections.

Leaves dry out and turn yellow

12.11%

The leaves have changed color and are flying around

12.33%

Large-leaved ficus trees with a significant rubber content and late-hardening trunks - Elastica, Bengal, Lirata - suffer from diseases a little more often. Soft, loose tissues are more susceptible to rotting than wood and are less treatable.

Pathogens can be brought into the home with a new plant. Therefore, it is recommended to quarantine them for a month away from other flowers, and carefully monitor them for signs of infection.

Ficus diseases, especially various rots, are often accompanied by improper care, namely: overwatering, high humidity and extreme heat. You need to spray leaves at a temperature of 27-30° C in the morning or evening, but not in the middle of the day.

Fungal spores can be introduced:

air flows during ventilation;
pets;
people touching flowers with dirty hands after walking or caring for infected plants;
if the ficus stands on a balcony or street - by birds, insects, raindrops, wind;

The cause of the disease can also be contaminated soil or one of its components, or an old pot that has not been disinfected when reused.

Pests attacking a plant

Spider mites on ficus, thrips on ficus, mealybugs - all these parasites can cause a lot of harm to your green specimen. For example, an invasion of spider mites is not immediately noticeable. It is quite difficult to detect parasites on a flower when there are only a few of them.

Nematodes penetrate the root system and cause the appearance of nodular and spherical growths on the trunk. The toxins released by these parasites gradually affect the entire plant; it needs to be cured and replanted in new soil. Before the procedure, the ficus is kept in an insecticide solution for several hours, completely eliminating dangerous infection.

Aphid

You can become infected with aphids from the air; they are carried in by drafts. A sticky whitish coating, similar to flour, appears on the foliage. It feeds on sooty fungus, which is dangerous for the bush. If there are several bushes, the infection spreads quickly.

If there are aphids in the house, they often infect not one, but several plants at once. We will have to resort to a comprehensive refurbishment of the premises. Insecticides are used, in addition to the standard treatment with potassium permanganate and soap.

Shchitovka

It reproduces in trays under plants, where water often remains. The insect sucks the juice from the foliage, depriving it of vitality. The presence of “swollen” brownish spots is a consequence of the introduction of scale insects.

If you notice an insect such as a scale insect, then you need to use the drug "Actellik". It is recommended to treat the plant with it at least three to four times a week. It is also often necessary to wipe the leaves with a soap solution.

Mealybug

Dangerous parasites that can suck all the strength from a plant and lead to death. Individuals reach 4-5 mm, their white cocoons and adult parasites are clearly visible on the ficus. The first sign of its appearance is the rapid fall of leaves.

Mite

Causes serious damage to ficus. Loves heat and lack of moisture. Leaves behind a barely noticeable cobweb and grayish-brown spots. The leaves begin to dry out and fall off.

Experienced gardeners suggest getting rid of swarms of ticks by using garlic tincture. To prepare it, take two heads of garlic. They are finely chopped and poured with a liter of boiling water. Place in the dark for 5 days, after which the same amount of water is added. You need to spray the inside of the leaves and stems, as well as the soil.

Thrips

Their effect on the plant is similar to the introduction of mites. Insects suck out vital juices; their comfortable environment is high temperature and dry air. They leave brown spots, causing the leaves and stem to dry out.

But a huge colony of ticks is more difficult to fight. That's why it doesn't hurt to regularly inspect the flower to look for mealybugs or aphids on the stems and leaves. If aphids appear on a ficus, how to deal with them? Buy effective insecticides and carefully treat the flower.

There are white grains on the ficus leaves

Ficus is quite resistant to pests and diseases, but it happens that it freezes or dries out. The main symptom of a plant disease is falling leaves or the appearance of plaque and spots on them. To know how to deal with a problem, you need to understand the cause.

Common problems

If you do not comply with the growing conditions, then the ficus will not look healthy. It is not necessary that the bush is affected by insects or disease; sometimes the problem is due to insufficient lighting.

Pale and yellowing of the leaves indicates a lack of the required amount of light. In this case, you just need to move the pot closer to the window, and in winter add artificial lighting.

The appearance of brown spots is a sign of a burn from direct sunlight.

It also happens that the falling of leaves and the appearance of blackening are the result of frostbite on the plant. You can revive the plant at home. The most important thing is to eliminate the source of the draft and create conditions for resuscitation.

Under no circumstances should you water the flower; you need to wait until the soil dries well. The necessary moisture is provided by spraying the foliage with warm and settled water. As soon as new shoots appear, it is possible to resume watering and use Kornevin, a growth activator.

"Orton Growth" is used as a top dressing 2 times every week.

If the flower dries out or has already dried up, then you need to restore it immediately. To do this, use high-quality watering and a lot of diffused light in combination with stimulants. The root system is freed from the soil and placed in water, waiting for new shoots to appear.

Diseases

Ficus Benjamin diseases always develop due to unfavorable growing conditions. The main reasons for this are low temperatures (below 60°F) and overwatering.

Effective tips for maintaining a healthy plant include using pathogen-free planting soil and container and disease-free seedlings.

It is worth taking a closer look at common problems with ficus and how to solve them.

Leaf fall . This is the most common problem for new growers and is usually caused by temperature changes. Ficus likes constant conditions, so it is necessary to maintain the same level of heat and humidity. A change in these two factors, even within 5-10 degrees, will cause leaves to fall. The only way to eliminate the problem is to stabilize the environment and continue to regularly water and fertilize the flower.
Brown spots. Cercospora blight looks like tiny black spots on the leaves. In this case, they may turn yellow and fall off. The grower will need to remove diseased shoots and spray the plant with a specialized product, and subsequently prevent high humidity. The use of sulfur helps, it is sold in sprays. Copper-containing fungicides can be applied at the first sign of the disease to prevent its spread. Organic products will prevent spores from germinating.
Anthracnose . This disease manifests itself as rusty spots on stems and leaves. When a problem occurs, remove diseased leaves and then practice good sanitation. Collecting and disposing of all affected plant parts and providing adequate light, water and fertilizer will strengthen the plant's ability to resist the fungus. Chemical treatments are rarely used because they can be harmful to occupants indoors.
Juice oozes from a ficus tree. This condition is caused by the appearance of sucking pests. Mealybugs appear as small cottony clumps, and scales appear as white or black spots on the stems and body of the tree. The problem can be eliminated by using horticultural oils or a soap solution - 1 tablespoon of soap per 4.5 liters of water.
The appearance of inflamed areas. Such swollen places can form on leaves (in large veins), stems, and sometimes roots, near stem cuttings. It is caused by a bacterium. It can be destroyed by removing affected plant parts to prevent spread. Using herbal sprays containing copper is an effective treatment for this condition.
Black spots. Very small marks usually develop on the underside of the leaves. This is nothing more than a fungus; when the infection is very severe, the foliage turns yellow and falls off over time. Further spread of the disease can be prevented by removing infected areas and spraying with a fungicide. Spotting can also be caused by canker sores. The spots may appear rusty and at times ooze juice.

Ficus benjamina diseases

This species is popular due to its beautiful glossy leaves and stems that can be intertwined. Grows up to 3 meters high with proper care.

Causes of ficus disease:

Improper care;
Fungal infection;
Reproduction of pests.

Due to improper care, problems appear in the form of root rot and the appearance of spots on the leaves.

Root rot develops due to systematic waterlogging of the soil. In a humid environment, a fungus develops that affects the roots. This causes the leaves to change color to yellow and become limp. Within a short time they darken and fall off. The soil may become crusty. As a result, the plant dies.

How to treat it? Pull the flower out of the pot and shake it lightly, clearing the roots from the soil. If they are dark and soft, the plant is dead and nothing will help it. When the main part of the roots is healthy, you need to trim off the spoiled roots. You also need to rid the crown of diseased leaves and branches. Replant the plant in a new pot with fresh soil.

You can water the flower only after new leaves appear and then maintain the watering regime.

Light brown spots may appear localized at the tips, along the edges or throughout the entire area of the leaves. Then they dry out and fall off. This is caused by too high a temperature and dry air. This often happens due to an excess of fertilizers in the soil. Eliminating the causes of its occurrence will help get rid of the problem. It is necessary to place the plant in a cooler place, increase air humidity and postpone fertilizing the soil.

There are other problems associated with pests and infections.

If rust appears on the leaves of Ficus Benjamin , then the problem is the fungal disease Anthracnose. Botrytis is similar, but in this case the spots become yellow-brown in color. Over time, the spots turn into ulcers, the plant sheds its leaves and dies. For treatment, it is necessary to remove all affected leaves, treat the ficus with a fungicide solution and move it to a less humid place.

Fungicides are chemical solutions used to control fungus on plants. They also treat seeds to remove fungal spores. The concentrate of the substance is toxic to humans, but a properly prepared solution will not cause harm.

Cercospora blight is another fungal disease that appears on ficus as numerous black spots on the bottom of the leaf. As the disease progresses, they turn yellow and fall off, and the plant dies. Treatment according to a similar scheme: remove the affected areas, treat with an anti-fungal solution, water less often.

Sticky leaves and black coating are a progressive sooty fungus on Ficus Benjamin. It affects areas with waste products of parasites. The scale insect on Benjamin's ficus leaves behind a sticky trail on which it settles. Cleaning with soapy water will help.

White coating on the leaves indicates mealybug . At the initial stage, a solution of laundry soap will help; if the flower is severely affected, then the diseased leaves are removed and the ficus is treated with a fungicide.

When a ficus grows in a warm and humid room, it can be affected by gray rot . This is mold, if you shake the leaf, you can see how its spores fly away (they look like gray dust). Brown spots appear on the foliage; if no action is taken, they grow. The leaves darken and fall off. This disease is treated with a solution of an anti-fungal drug. You need to water the flower less often during treatment.

Ficus pests

All types of pests affect the same, despite the fact that they are rubber plants. Due to the small plates, they are the most difficult to detect on the Benjamin ficus.

Flying insects and bugs reach flowers through open windows or vents. The sedentary ones move from infected plants. Animals, people on clothes or shoes can bring pests into the house.

It is important to quarantine new plants away from other flowers. It is very inconvenient to destroy insects that attack potted crops, especially in winter, in a city apartment, on large specimens.

Indoor plants tend to “exchange” parasites, so Ficus can be colonized by any pests, even though there are only four typical for the crop. These are mealybugs, scale insects and false scale insects belonging to the Coccoidea family, and spider mites.

Aphid

Aphidoidea is a large superfamily of insects that suck juices from the soft tissues of plants, leaving a sticky coating on the vegetative organs. They often spread viruses. They interfere with photosynthesis, causing the leaves to turn yellow and fall off.

The pest is a small winged insect. Color depends on the species. Aphids appear infrequently on ficus trees; they usually move from neighboring plants when there is little left to profit from. Prefers young leaves or shoots. If there is a strong infestation at the tips of green twigs, you can find a whole colony of pests clinging to them.

To kill aphids, parasites are first removed with a soap solution, then treated with an insecticide.

Scale insect and false scale insect

A typical pest of ficus. A sedentary insect, covered with a waxy coating, tightly attached to leaves or stems. It looks like a small oblong plaque, it just doesn’t want to come off - to remove the scale insect mechanically, you need to scrape the plant with the tip of your fingernail or a hard instrument.

It is difficult to destroy the pest - due to the wax covering the shell, even repeated treatment with chemicals does not always give a 100% effect. One female will go unnoticed and will give rise to a new colony.

It is recommended to first remove insects mechanically, for example, using an old toothbrush. Then you will have to treat the tree with an insecticide several times, the frequency and interval are according to the instructions.

Ficus benjamina pests are especially difficult to remove due to its numerous small leaves. A scale insect can be attached to each plate, petiole or axil.

Whitefly

A flying insect with a light-colored body and wings, as if sprinkled with flour. Depending on the type, it has a length from 1.2 to 3 mm. The pest rarely settles on ficus trees, usually in greenhouses.

It has been noticed that if two plants of the same species and age stand nearby, the whitefly will unmistakably choose the weakened one. The second will not touch, even if their leaves touch. Healthy ficuses are attacked last, or when there are no other flowers in the house.

Fighting the pest is difficult because it flies beautifully. All plants need to be treated at the same time. If the whitefly is noticed in time, you can get by with traps or folk remedies. Will help:

infusion of garlic or yarrow;
tar soap.

Mealybug

Another typical pest of ficus. It is a soft-bodied scale insect covered with powdery wax. Males fly, females prefer to hide in the axils of leaves, they are 3.5-5 mm long and white in color, which is why they are clearly visible.

The scale insect sucks juices from the young vegetative organs of the ficus. Leaves and shoots become deformed and become covered with cotton-like discharge. Growth slows down, branches dry out.

The pest can be removed from ficus trees mechanically using a cotton swab or swab dipped in a soap solution. Then, at intervals of a week, spray three times with an infusion of garlic, tobacco, or pharmaceutical calendula.

Spider mite

The difficulty of pest control lies in two points:

It is very small and can be detected by indirect signs or using a magnifying glass.
This is not an insect. The mite belongs to the class Arachnids (arachnids), and conventional insecticides simply do not work on the pest. We need those that have acaricidal properties.

Inexperienced gardeners may mistake the “work” of Tetranychidae for chlorosis. With severe damage, the leaves turn yellow and fall off. You can determine that the ficus is suffering from a mite invasion by examining the back side of the plate. It is covered with a gray coating and thin cobwebs.

Spider mites appear on ficus only when air humidity is low. The best prevention is regular spraying of the leaves with warm water.

Thrips

The pest is a small insect with a dark elongated body measuring from 0.5 to 2 mm; it flies poorly, but runs quickly. The mouthparts are piercing-sucking type. The color depends on the species; there are about 300 of them in the countries of the former USSR alone.

Pests inhabit the underside of leaf blades and feed on ficus juices. At the sites of bites, yellow or colorless dotted spots first appear, then they merge, turn brown, and the leaves fall off. It is recommended to immediately treat the ficus with Actellik.

Nematodes

A dangerous pest that attacks roots or stems. In the first case, the underground part dies, having previously become covered with growths - galls. In the second, the trunk cracks and the leaves become deformed.

There are few drugs that can cope with nematodes; they are poorly suited and ineffective for potted crops. It is recommended not to start treatment at the slightest suspicion, but to immediately destroy the plant and throw away the substrate and container.

Diseases of Ficus Rubber

This evergreen plant with large shiny leaves is often grown as an ornamental plant and, like other species, is susceptible to various diseases.

The most common leaf diseases are:

Blackening and falling off. The reason is waterlogged soil. Solution: let the soil dry, cut off the rotten roots, water only when a third of the soil level in the pot is dry.
The appearance of red spots. These are burns caused by direct exposure to sunlight after spraying. This is especially true for plants located on the south side. It would be correct to move the plant to a shaded place, but not to the darkest corner.
White spots. They talk about hypothermia of the ficus. You need to move the pot to a place where there are no drafts. The most frozen leaves will eventually dry out and fall off on their own. Others will remain with stains. If you create normal conditions for the ficus, new leaves will grow of a uniform color.
Acquiring an abnormal shape at the edges. The problem is in the root system; most likely, the small roots were damaged during transplantation or from waterlogging. Solution: water the ficus less often, add nutrients for the roots.

More often than others, it is the rubber-bearing ficus that is affected by anthracnose. In this case you need:

Reduce watering to a minimum.
Set the pot away from other plants (or isolate it with a partition).
Remove leaves with visible spots.
Remove old soil and disinfect the pot.
Treat the roots with a weak solution of potassium permanganate and transplant the plant into new soil.

Also, small brown streaks may appear on this type of ficus, which indicates a pest. These are Thrips larvae. The result of their vital activity is also a silvery coating and small red dots. It is necessary to treat the leaves and soil with a fungicide solution. Simply removing the affected leaves will not work - the larvae also live in the soil.

White plaque in the form of dots indicates the development of spider mites. To get rid of the parasite, the flower is washed well and then treated with a chemical.

Diseases and pests of Ficus Benjamin with photos, ways to combat them | Exemplary Estate

Ficus, like all indoor plants, can get sick from time to time or become prey to pests.

Of the diseases that this plant can suffer from, the most common are root and tuberous rot, as well as leaf spot.

The most common pests include spider mites, scale insects and mealybugs. In addition to all of the above, the ficus gets sick from improper care.

The most common problem when growing ficus benjamina is considered to be yellowing and falling leaves, and the most common questions are: why does ficus benjamina shed leaves, ficus benjamina why leaves fall and ficus benjamina leaves turn yellow - why? Let's look at the answers to these questions.

Air temperature

Yellow leaves - lack of care

This plant not only does not tolerate sudden changes in temperature, but also reacts poorly to air that is too cool or too hot. When the temperature drops below +17°C or when it rises above 25°C, the plant may shed its leaves.

Air humidity

Ficus benjamina loves moist air; when the air humidity drops, the plant's leaves begin to turn yellow and fall off. In this case, there is only one way out: increase the humidity: either spray the plant several times a day, or buy an air humidifier.

Watering

Violation of the watering regime also leads to yellowing and falling of leaves, and this occurs both from underwatering and from overwatering of plants. To determine whether the plant needs to be watered, you need to: pierce the soil with a stick and see how dry it is; if the wet layer is 2-4 cm from the surface, you can water it.

Fertilizers

It is worth paying attention - the leaves are falling

Both deficiency and excess of nutrients affect the condition of the leaves and the entire plant. The main thing here is regularity without excesses. Read all the rules for caring for Ficus Benjamin in the article: Ficus Benjamin: cultivation and care

In addition to everything described above, the leaves of this plant turn yellow and fall off due to disease and pest damage. Read about diseases and pests below

Ficus benjamina diseases

Root rot

The cause of the disease can be called a fungal disease of the root system. Root rot or root rot can occur when the soil is systematically waterlogged. So this disease can be called a consequence of improper care.

Surgical treatment of root rot

If in the pot where the ficus grows, a crust forms on the surface of the soil, then the disease begins to progress due to the lack of oxygen.

Signs of the disease: the leaves begin to turn yellow and wither, then darken very quickly, and the plant dies as a result.

The disease can only be treated if you pay attention to it at the very beginning. Root rot can only be treated surgically.

Treatment of root rot

If the plant shows signs of the disease indicated above, the plant should be removed from the pot and the soil should be carefully shaken off the roots. After the roots are cleaned, inspect them very carefully. If the roots of your ficus have almost all darkened and are very soft to the touch, then nothing will help the plant and you can throw it away.

Pruning affected roots

If the roots are mostly white and quite elastic, then the plant can be saved and this must be done immediately. To do this, cut off all darkened and softened roots. You should also prune the crown; first, remove all leaves and branches with traces of the disease.

After this, estimate in percentage terms what part of the roots you cut off; the same percentage of roots should be removed. This is done so that the plant can devote all its energy to recovery and restoration, and not to maintaining a large crown. After this, you need to take a new pot and plant the plant in fresh soil.

Next, you need to water the ficus with a solution of the fungicide carbendazim.

Place the ficus pot in a bright place, but not in direct sunlight. Watering can be done only when the plant moves away and produces new leaves. After recovery, follow the watering regime to avoid the disease in the future.

Leaf spotting - care problems

Ficus leaf spot

Leaf spotting on this plant usually occurs due to improper care. Before determining the cause of the disease, you need to carefully examine the plant. Poor care, anthracyclosis and cercospora can lead to the disease.

Ficus Robusta diseases

This is a popular variety of rubber ficus. It grows tall and sometimes needs special supports. Easy to care for and resistant to pests. But if normal conditions are not maintained, he can get sick.

So, you need to pay attention if the leaves turn yellow and fall off quickly. The reason may be a draft or improper care - lack of light, infrequent watering.

Brown spots have formed on the leaves - the soil is waterlogged. Over time, a rotten smell may appear. This indicates that the root system is suffering and you need to inspect the roots, replant the flower and adjust the watering regime.

Scale insects or spider mites appear if the flower is in a room with warm and dry air. Regular spraying of the crown and optimal temperature (25-30°C in summer, 16-20°C in winter) will solve the problem.

When care is carried out correctly and regularly, there are no pests, but the ficus Robusta continues to shed leaves - this indicates stress. It manifests itself if you frequently rearrange the plant, or place it in an inappropriate place (for example, a corridor).

Ficus diseases and their treatment with photos

Ficus is a picky plant. Does not require special knowledge or care skills. But if you don’t pay attention to it at all, and don’t follow the basic rules of maintenance, the flower will begin to fade. Some ficus diseases can cause not only deterioration in appearance, but also its death.

Why do ficus trees get sick?

First of all, improper maintenance conditions lead to withering:

strong changes in air temperature in the room, or its constant overestimation;
dry air, drafts;
insufficient or, conversely, too bright lighting;
inconsistency with the watering regime: too frequent or, on the contrary, insufficient;
improper mineralization;
contaminated soil.

Having corrected these shortcomings, the ficus will quickly return to normal and reward it with bright colors.

But some diseases are caused by more serious reasons: ficus can be attacked by fungal diseases and pests, photos of which will be given below. They require more attention and time, and in some cases, disposal of the flower.

Leaf diseases

The appearance of the plant will help determine the cause. The leaves will be the first to tell you about “problems”:

Yellowing

Reason: the air in the room is not humid enough, the air is too warm, or the lighting is too bright. This happens more often during the heating season, or when the ficus is standing on a windowsill on the south side - the sun's rays burn it, it turns yellow and begins to fade.

How to fix it: remove it from the heater or sun, humidify the air, for this you can use a humidifier, or a moistened towel that is hung on the radiator. As it dries, the procedure is repeated. Spraying the leaves more frequently will help.

Important! You cannot spray the ficus by leaving it in the sun; water and rays can cause severe burns, leading to death.

Frequent changes of location can provoke yellowing. The flower does not have time to adapt; it “speaks” about its well-being with its appearance. You need to immediately determine its place in the house, taking into account the convenience of the owners and the new resident himself.

They become small and fall off

There are not enough nutrients: replanting into a new, correctly combined soil will help: peat, leaf soil, sand are mixed in equal proportions. After transplanting, water.
Excess moisture: this will be indicated by spots on the leaves, yellow edges and falling off. You need to wait with the next watering until the soil dries completely, then continue watering moderately. If the leaves begin to fall off significantly, immediate replanting is necessary, and the rotten roots of the plant must be removed.

It is important not to forget that rare watering will also affect the condition of the leaves - they will wrinkle and dry out.

If this is not corrected in time, the roots will dry out, which will be impossible to correct.

High temperature, dry air, excessive feeding:

Brown spots form on the leaves. This can be corrected by eliminating the cause.

They only fall from below

There is no need to worry if new healthy leaves immediately grow. If this does not happen, the trunk continues to become bare - a transplant or additional fertilizer is required.

Continue to die off, despite the elimination of shortcomings

In this case, there was some infection or pest damage. Insecticides are needed here. But in order to select them correctly, it is necessary to conduct a thorough analysis of the plant and identify the pathogen.

Fungal infections

Gray rot or Botrytis: appears in flowers kept in a warm room with high humidity.

The ficus is covered in places with a gray coating. When shaken, dust rises up. The leaves begin to darken and then die.

To eliminate the disease, remove all affected areas of the flower and allow the soil to dry. Next, regulate watering and ensure frequent ventilation.

Sooty fungus: appears on the surface as a black coating. The precursor to the disease is the secretions of insect pests.

For small affected areas, treat them with soapy water, passing a sponge over each one separately. Severely affected units are removed and destroyed, and the stems and roots are sprayed with fungicide.

Pythium, late blight, rhizoctonia: fungi provoke rotting of roots and stems. The plant stops growing and gradually dies. It will not be possible to save it; it must be eliminated before other flowers become infected.

For prevention, moderate watering is needed, once a month with a weak solution of manganese.

Powdery mildew: appears as white powdery spots. Its appearance is provoked by high humidity and heat. For treatment, spray with a solution of copper sulfate and soda ash: dilute 10 g of soda, 2 g of laundry soap in a liter of water, stir 2 g of sulfate separately, pour the mixture into the main composition. Bring the volume to 2 liters and spray with it.

Rust (anthracosis): expressed by spreading yellow-brown spots, the edges of the leaves look burned, sometimes pitted with ulcers. To get rid of it, the plant is cleaned of affected areas and treated with a fungicide.

Advice! To make an accurate diagnosis, it is better to compare the identified signs of ficus disease with photographs, and then their treatment will be more productive, and other flowers will be protected from infection.

Spider mite. The presence is indicated by spots of a gray or brown tint, and in places a thin cobweb may be visible. The environment for development is dry and warm, this promotes rapid reproduction. Leaves damaged by it dry out and fall off. To avoid damage to the ficus, optimal humidity should be maintained in the room, the plant should be sprayed with water, and occasionally wiped with a solution of laundry soap. If affected, treat with an insecticide.
Aphid. The appearance of a sticky coating, yellowing and deformation of leaves is the result of aphid parasitism. Insect secretions become a breeding ground for fungal infections, which will lead to the destruction of the flower. Treatment with soapy water and insecticides will help.

Thrips. Small black bugs. They settle on the back side of leaves and drink plant sap. Infestation appears as brown, white and yellow spots. To get rid of the pest, they are treated with the following drugs: Actillic, Tanrek, Aktara.

Prevention of diseases

Proper bush care will help minimize the risk of ficus disease. You should adhere to the watering schedule, feed with mineral components and cut off dry leaves and branches on time. The plant also needs to receive the daily norm of light and heat; the air in the room should not stagnate.

To protect the rubber ficus from infection and pests, you need to follow a number of rules:

The newly acquired flower must be kept in quarantine for some time. Typically, the isolation period is no more than a week. It is better to keep the ficus in a separate room so that the disease is not transmitted through the air. If after a week of quarantine no infectious diseases have been identified, the plant can be placed next to others.
It is advisable to inspect flowers every day. Particular attention should be paid to the lower part of the stem and the inner surface of the leaves.
Every month, ficus foliage should be treated with soapy water. This procedure is vital for bushes located on open loggias or growing outdoors.

How to protect ficus trees from diseases

Proper care and attention is the best way to avoid diseases of any indoor plants. But sometimes it happens that ficus diseases appear already in the first days after its appearance. To avoid this, there are mandatory preventive measures that will protect you from this fate:

When purchasing a flower, carefully inspect it for traces of parasites. The slightest manifestation of ficus leaf disease is a reason to refuse the purchase, or be ready to begin treatment;
even if the ficus looks perfect, it is quarantined for a week, away from other plants; after time, if no signs of disease have appeared, it is installed in a permanent place;
when arranging flowers, it is important to maintain a distance between them;
wash with soapy water from time to time;
When replanting, disinfect the soil, pots and trays with a weak solution of potassium permanganate.

Following these simple rules will save time, keep your home garden healthy and ready to serve its owners, delighting with its aesthetic appearance and clean indoor air.

Prevention measures

To avoid the spread of diseases, it is necessary to carry out preventive measures in a timely manner, which include maintaining an optimal indoor microclimate and proper care.

Basic preventive measures:

Maintaining temperature within +17…+25°С.
Maintaining humidity within 60%.
High-quality ventilation of premises.
Annual replanting for plants up to 3–4 years old, then every 2 years.
Irrigate only after the top layer of soil has dried to a depth of 2–4 cm.
Providing an abundant flow of diffused light.
Application of complex fertilizing from May to September once every 2 weeks.
Timely removal of old, broken, underdeveloped shoots that thicken the crown.
High-quality disinfection of soil during planting/transplanting.
Preventive treatments with Fitosporin once during the entire active growing season.

Did you know? Ficus Benjamina is a valuable medicinal plant. Its leaf blades, crushed into pulp, help heal wounds.

Most often, Ficus Benjamin is susceptible to fungal diseases. You can avoid their spread by properly caring for the plant.

Fungicide for the treatment of rubber

The fungicide solution helps control pests well. Today there are several biological poisons that help effectively fight ficus diseases:

Copper-containing (iron sulfate, manganese, potassium). Effective against anthracnose, powdery mildew and a number of pests.
Organic , based on a number of chemical compounds. Used against fungi. The effectiveness depends on the specific plant and the severity of its damage.
Biological - fights diseases, rot and insects well.

In specialized stores you can always find the necessary drug to save the plant.

Thus, spots on ficus leaves are an alarm bell. This means that the plant has been attacked by pests, bacteria or fungi . It is urgent to understand what the reason is and begin to act. Untimely control methods can cause the death of the tree.
