Aloe diseases - what they are. Aloe diseases - what are they? Why do brown spots appear on aloe?
- violation water regime, which leads to the accumulation of water in the ground;
- violation of the light regime;
- incorrect application of fertilizers.
Problems with a flower (disease or insects) can appear even with a slight violation of the rules for maintaining a succulent.
Let us consider in more detail each reason that can provoke the death of the agave, as well as its infection with pathogenic microflora or pests.
Excess moisture
Aloe is a succulent. Therefore, he is able to remain without water for some time without serious consequences. Watering from spring to autumn is carried out once a week. In winter, you should reduce the amount of moisture added to the pot. At this time, the flower is watered 2 times a month, or even less often.
If you flood a plant, excess moisture in the ground most often leads to rotting of the root system. Affected roots may simply burst when pressed.
As a result, homemade aloe shows signs of nutritional deficiency: the leaves begin to turn yellow and dry out, spots appear on the leaf blade, the blade itself becomes soft and may even begin to rot. If you don't know why aloe leaves turn yellow, study its roots. Perhaps they are the problem.
It is worth noting that excess soil moisture serves as an excellent environment for the development of various diseases. If nothing is done, the plant may eventually die.
Incorrect lighting mode
Agave is considered light-loving plant. Therefore, it should grow on east or south windows. At the same time, direct sunlight may fall on it, because in wildlife aloe grows in desert regions. In summer, the flower should be placed outside so that it receives sunbathing.
If there is not enough light, the aloe leaf will become pale and watery. Then the thin stems will begin to rot. First, the tip of the leaf will turn brown, and then the pathology will spread to its entire surface. In order to keep your family doctor, you need to understand why aloe rots or begins to wither.
Errors in feeding
Mistakes in fertilizing a pot with this indoor flower can lead to the root receiving a chemical burn. This will lead to the death of the aloe. If over-fertilized, the fleshy leaf will begin to turn yellow and soon fall off. Leaf fall usually begins with the lowest leaves. Dried leaves can break easily.
As you can see, the external manifestations of all three violations in the care of this medicinal succulent have similar symptoms. Therefore, it is very difficult to immediately determine why aloe leaves dry. By identifying the cause of the pathology, as well as related problems (diseases and pests), you can have time to save the plant.

Root rot
Agave, more often than other diseases, begins to die due to developed root rot. This type of rot occurs at low temperatures and excessive watering. If the disease is not detected at an early stage, the flower will definitely rot. If he dies, he cannot be revived by any means.
The following signs indicate root rot:
- growth slowdown;
- the stem begins to dry;
- adding water does not improve the situation.
If these signs are present, you need to check the roots and remove all rotten shoots. There are no other ways to save aloe.
Dry rot
Unlike root rot, the dry variety has no external manifestations. The flower can rot very quickly. At the same time, it is generally unclear why aloe dies.
Pests
Spider mite
Interestingly, the leaves first turn yellow and then turn pale. This is very similar to lack minerals in the soil. At a later stage they become scarlet. If you do not find out correctly why the aloe turns yellow, you may lose the flower altogether.
Scale insect and false scale insect
To combat false scale insects and scale insects, you need to spray the flower with special preparations, and also set it aside from others indoor plants. Often folk tinctures made from garlic or soap solutions help cope with these pests.

Prevention measures
You can avoid infecting a flower when its leaves turn yellow or begin to curl by doing the following:
- correct watering of the flower. Moreover, you should not allow excessive moisture and dryness;
- preventive spraying against diseases and pests;
- creation for a flower optimal conditions content;
- fertilizing only during the warm period and no more than once a month;
- periodic inspections of the plant. They will allow you to identify the first signs of disease or the appearance of insects.
Now you know that if aloe dries out, you need to quickly look for the reasons. What if your “home doctor” is attacked by pests or gets sick?
Aloe is a type of succulent plant, and its name means “bitter” in Arabic. Even in ancient times, people appreciated the benefits of this culture and also learned to use its juice and leaves. This juice is considered a preventative and remedy. It is used both and. These days, aloe can be found in many houses and apartments. Its popularity is due to medicinal properties culture and ease of care. But, despite the undemanding culture, aloe diseases are far from uncommon.
Features of aloe care
To prevent aloe from developing diseases, it is necessary to provide it with quality care. Here important factors for the favorable development of this culture:
Need to create good lighting. It is better to place the container with the plant on the windowsill on the south side. In cold times additional lighting won't be needed.
In summer, the temperature should vary between 22-26 degrees, and in winter up to 12 degrees. In summer, the flower can be taken out onto the terrace.
Tolerates lack of humidity in the air. But in the summer, the air around the flower can be treated with a spray bottle. The accumulation of moisture on the leaves can cause fungal infections, and rotted leaves can also form.
The bush requires abundant watering. Between procedures, the soil should have time to dry.
In order for plants to develop well, it is necessary to provide them with nutritious soil. For this ready soil you can buy or make it yourself. To prevent any diseases from appearing, it is recommended to carry out regular feeding.
Common problems with aloe
Many beginners don't know why different types aloe leaf tips dry out. Most often, this means that the plants have not been replanted for a long time. In this case, the roots occupy all the free space in the container, as a result of which the aloe does not receive a sufficient amount of useful components. Therefore, if the tips of aloe leaves dry out, then it is urgently necessary. Before transplanting, the plants are not watered to make it easier to remove.
What to do with curled leaves
It is also important to know what to do if the aloe leaves curl. This sign indicates that the seedling lacks normal care. It is necessary to wipe the leaves from dirt, and also sprinkle them with water at least once a week.
If the plant has thin leaves, this may be due to lack of lighting or lack of humidity.
Rotten Roots
But if the root has rotted, then this is evidence of the most common mistake, too much. If the roots have rotted, then the bush needs to be removed and the damaged parts removed, and the aloe leaves must be sorted out.
Every gardener needs to have an idea of how to save a flower if the leaves turn yellow. Most often this happens due to insufficient nutrition.
The leaves may turn yellow if you forget about fertilizing. Therefore, aloe at home must be treated with special fertilizers for succulents. Also, a yellowish tint may appear if the flower does not have enough light.
What do the spots mean?
You can identify plant problems by looking at the color of the leaves. These may be the cases:
Brown spots on the leaves indicate that the bushes lack moisture. In this case, you need to reconsider the watering scheme and periods.
If the spots are dark and soft, then the plants are dying from the fungus. In such a situation, you need to treat the bush with an antifungal drug.
If the flower has acquired a black leaf, this indicates severe contamination. In this case, the salvation lies in maintaining cleanliness and wiping the plants from dust.
But if the leaves in the agave turn red, then this is not dangerous. Thus, the flower reacts to the sun's rays. If you put it in a darker place, the leaves will soon return their color.
Other problems:
Sometimes the plant withers and dies right before your eyes. If the leaves begin to curl and fall off, the water for irrigation is too cold. The flower may die if the leaves turn pale and wither. This happens when you water too much.
If the tips of the leaves of any aloe dry out and the edges turn yellow, then water with chlorine was used for irrigation, and the plant also lacks potassium.
What diseases affect
Most often, aloe is affected by two diseases - root and dry rot. With root rot, the roots rot from too much water in the pot. In this case, the stem begins to dry out, and the plant does not change its size for a long time. To cure a flower, you need to dig it up and then trim off all the rotten roots. The remains are sprinkled with coal powder or sulfur. Then the bush needs to be moved to new soil. After illness, watering should not be done for three weeks. This disease is difficult to treat, so sometimes the seedling has to be completely removed.
With dry rot, the bush can die unnoticed, since the flower dries out from the inside, but this does not manifest itself externally. For prevention, it is necessary to spray the plant with a fungicide from time to time.
Aloe pests
The plant may also curl, change color, and weaken due to pest damage.
Spider mite
Considered the most dangerous spider mite. It is very difficult to notice, since its dimensions are no more than 1 mm. In this case, the leaf may become covered with white spots and a barely noticeable cobweb may appear. At a later stage, the stems and leaves turn scarlet.
To treat the scourge, drugs such as acaricides are used. As a preventive measure, the plant can be wiped with garlic tincture or an alcohol solution.
Shchitovka
These insects can be easily seen. They are brown in color and look like plaques on the leaves. At the same time, the leaves dry out and curl, and redness appears. brown spots.
To combat such pests, you can use garlic tincture, which is rubbed on the leaves.
Mealybug
When infected by this pest, the flower becomes covered with a white coating. In this case, the aloe may rot. It is not difficult to fight such an insect. Since it does not tolerate moisture, each leaf must be washed with an alcohol or vinegar solution. For preventive purposes, dry air and soil should not be allowed. Leaves need to be cleaned frequently with a damp cloth. This type of care will help prevent pests from appearing.
Such insects appear in humid and hot rooms. Pests can be recognized by silvery stripes on the leaves. To combat such insects, they are used chemicals. After treating the plants, the procedure must be repeated a week later. It is better to take the affected plants to another room.
Despite its endurance and vitality, aloe requires special care. At proper care And preventive measures you can grow a beautiful and healthy plant that will decorate your apartment for many years. Timely treatment of diseased or pest-affected leaves will help save the plant.
Withers
It happens that a succulent withers for no apparent reason. In this case, you should do the following:
- Stop overwatering.
- Do not let the earthen coma dry out too much.
- Provide sufficient light.
If this does not help, then the reason lies elsewhere. Perhaps the aloe is withering due to rotting roots. In this case, it will have to be transplanted.
Dries up
The main reason that aloe leaves dry out is improper care. This can also happen if the plant is affected by some kind of disease or pest. In this case, the main thing is to notice the disease in time and provide proper assistance. How to properly care for aloe so that its leaves do not dry out?
- There must be sufficient sunlight.
- The soil must have nutrients.
- It is necessary to observe the temperature regime.
- Frequent watering is not recommended; it is optimal to water the plant twice a month.
You will find detailed information about why aloe may dry out and what to do about it, and read about the reasons that aloe begins to turn yellow.
The leaves are falling
Falling leaves indicate that the care of aloe has changed or the conditions have changed. Often leaves fall off due to lack of watering cold water .
You can save it as follows:
- Stop watering the plant with cold water.
- The water must be settled.
- Let the flower rest from the liquid for a while.
Read about what problems with leaves can occur in aloe and how to deal with them.
The plant has died or rotted: reasons and what to do
Why might the flower die? This could happen as a result of a serious illness that was neglected or improper care. It is very important to notice and diagnose the disease in time, so that you can then know how to deal with it. Timely detection of the disease is the key to successfully saving the plant.
Important: If the aloe is completely rotten root system, and along with it the stems, then such a plant cannot be saved, all that remains is to throw it away.
The only option to revive it is to try to transplant the cut stem into a clean container with new soil. You will need cactus soil mixed with river sand and rotted earth. The succulent also needs good drainage..
How to take care so that the agave does not disappear?
- Young aloe should be kept in big pot with a drainage hole at the bottom.
- For better water drainage, expanded clay should be placed on the bottom as drainage.
- You should not water frequently; several times a month is enough. Water should not remain in the pan; excess water must be drained.
- It is best to place aloe on the south side.

What aloe diseases do flower growers most often encounter? These are root rot, nematodes, thrips and spider mites. Often aloe leaves turn yellow, become soft or curl. Why do aloe leaves turn yellow, dry out, and curl? What to do? Experts solve a number of problems with growing aloe, and will also tell you how to professionally deal with pests and plant diseases. Photos of aloe will help you understand the signs.
Aloe diseases due to improper care
Due to improper care, aloe most often dries out and turns yellow. The plant's leaves also curl and turn red. Universal solution there is no problem, and therefore experts consider each case separately. So, what to do if the aloe leaves curl and turn yellow, or the plant itself dries out or rots? Consultation with photos from professional flower growers.
Why does aloe have thin leaves and the plant itself stretches out? In this case, the plant does not have enough sunlight. From a lack of lighting, aloe begins to grow rapidly upward, as if making its way to the rays of the sun, while spending a colossal amount of energy on growth. At the same time nutrients the plant does not have enough to grow full-fledged green mass, and therefore the aloe leaves become thin. You can solve the problem by moving the flower closer to the window or placing it under artificial lighting (in winter time). If there is no artificial lighting, then it is recommended to reduce the temperature of the aloe and reduce the number of waterings. Thus, all physiological processes in the plant slow down and it will not stretch. With the onset of spring, aloe provides required level illumination These should be windows on the east or west side of the house. If the windows of the house face south, then the plant must be shaded. It is also recommended to take the plant outside in spring and summer, but always with shading.
In aloe, the lower leaves became stained at the base and fell off. Reason: regular waterlogging of the soil, as a result of which the aloe root rotted, and the rot began to rise up the stem of the plant. What to do? The plant must be removed from the pot, all rotten parts removed to a clean cloth. A neat cut is made on the stem until the tissue at the cut site is completely clean. Next, the cut area is sprinkled with crushed activated carbon, the cut is allowed to dry for 1-2 hours, then the base of the plant is powdered with root, and the aloe itself is planted in a small pot (volume 100-200 ml). The soil should have the following composition: 1:1 peat and sand (sand can be replaced with perlite). Watering is very sparse, water through a tray, wet only the lower part of the pot where the aloe is planted. Only the bottom layer of soil in the pot should be wetted, followed by complete drying of the soil and again scanty watering. Do this until roots form.
Why do aloe leaves turn red?? Red or brown spots on aloe leaves are a protective reaction of plant tissues to bright sunlight, that is, it is a sunburn. Red spots on aloe leaves may appear in the spring, when the light level increases after short winter days. Over the winter, the plant has become unaccustomed to the sun and throws out the red pigment on the leaves for protection. Often red spots on aloe leaves appear if the plant is moved from partial shade to a windowsill under unshaded sun. Plant to bright light needs to be taught gradually. From an excess of sunlight, aloe leaves will not only turn red, but also wither or turn yellow at the tips.
Why do the lower leaves of aloe turn yellow? Massive yellowing of the lower leaves of aloe indicates errors in care. Thus, a warm winter in conditions of abundant watering and lack of light leads to depletion of the flower. As a result, the lower leaves of aloe turn yellow, when the crown becomes very elongated, and the leaves become thin and not so fleshy. What to do? If in winter it is not possible for the plant to receive artificial lighting for 12 hours, then reduce the temperature of its contents, down to +10 degrees (the plant must be accustomed to low temperatures gradually). At the same time, watering is reduced and aloe overwinters in almost dry soil.
Why does aloe turn yellow in summer? In summer, even in conditions of sufficient light, the lower leaves of aloe often turn yellow. This indicates violations of the root system, that is, the roots can rot from excessive waterlogging. Either the plant is watered too often or it is growing in a very large pot. If the aloe has stretched out and its lower leaves have turned yellow, you can re-root the top. In this way the plant is rejuvenated. The top is cut off, the cut is sprinkled with crushed coal, dried in the shade for 1-2 days, then the cut is sprinkled with roots and planted in a small pot. A 1:1 mixture of peat and sand is suitable here. Watering is very poor through the tray. Only the bottom layer of soil should be wetted. The next watering is only after the soil has completely dried out from the previous watering.
Why do aloe leaves turn yellow? Aloe leaves turn yellow if the plant is disturbed cold winter, but do not reduce watering. Or they sharply reduced the temperature of the plant. In the first case, the roots of the flower begin to rot, in the second, the roots become overcooled and become stressed. In both cases, it is necessary to reduce watering. The next watering should be carried out only after the soil has completely dried. You need to gradually accustom the plant to the cold.
Aloe leaves are soft if the plant is in direct sunlight. In this case, much more moisture evaporates from the surface of the leaf plate than the root system is able to absorb. However, excessive watering will not help here, but will only worsen the situation. After all, an excess of moisture can cause the aloe root to rot. The solution to the problem is simple - move the flower under a bright one, but diffuse light. This could be a place near a window with a light curtain hanging on it.
Aloe leaves are soft if the root system is rotting. There can be several reasons for the rotting of the root system. This is regular waterlogging of the soil, or low temperature keeping the plant in combination with regular watering, or a large volume of pot for small flower. In any case, the aloe is removed from the previous soil. reduce the volume of the pot, plant it in a mixture of peat and sand, and carry out scanty watering through a pan.
Aloe leaves curl for two reasons. The first reason is poor watering, high temperature contents and dry air in the apartment. In the summer, when it is hot outside and in the apartment, you need to water the plant abundantly, but only after the soil has completely dried out, spray it regularly, but after the sun has set. Otherwise, burns in the form of red spots will appear on the aloe leaves. The second reason is the hot winter. Aloe in winter is often placed on a window near heating devices. The air near the radiators is hot and dry, causing the aloe leaves to curl. In such cases, aloe plants are provided with artificial lighting away from heating devices, or they arrange a cold wintering.
Aloe leaves may curl if the root system rots. It is necessary to remove the plant from the pot and, without disturbing the integrity of the earthen ball, inspect the roots. They should be elastic and light. If the aloe roots are brown and flabby, they are rotting and must be removed. What to do next with aloe is written above.
Aloe diseases, photo
In addition to improper care, aloe can be affected by diseases such as root or dry rot, and pests such as thrips, spider mites, and scale insects. So, how and with what to treat aloe diseases? Photos and detailed instructions from specialists.
Aloe has stopped growing even during the growing season, its leaves turn yellow, in some cases the aloe leaves fall off the stem, and the plant itself falls on its side. Aloe disease: root rot. Causes of the disease: excess moisture. The root system suffers (rots) from excessive watering. How to treat aloe? The plant must be removed from the soil and the roots carefully examined. Rotten and flabby roots must be trimmed. The soil from the pot is thrown away, the container is disinfected. A mixture of peat and sand is poured into the pot. Aloe is planted there for rooting. Watering is carried out very sparingly and through a tray. When watering, only the bottom layer of soil should be wetted. It must be completely dry before the next watering. The lower the temperature of the plant and the less amount of sunlight ( artificial lighting), the less watering.
In particularly serious cases, root rot affects the aloe stem. The leaves and stem of aloe are covered with large spots that are soft to the touch. brown. The aloe root has completely rotted. Here you need to completely cut off the entire lower part of the flower down to the healthy tissue. Powder the cut area with crushed activated carbon. Let the cut dry for 1-2 days, then sprinkle it with root and plant it in a mixture of peat and sand (1:1). Plant care is described in the previous paragraph.
White spots like streaks appeared on the aloe leaves. They increase in size over time, and the disease spreads to other leaves of the flower and other plants. Affected aloe leaves turn yellow and dry out. Small black dots can be found on aloe leaves. Aloe disease: thrips. Black, small dots are excrement. How to treat? Isolate the affected plant. It is necessary to treat aloe with actara, according to the instructions. Treatment is carried out 4 times with breaks of 7-10 days. The higher the temperature in the house, the more often the treatment. For prevention, you need to spray the entire collection of flowers with actara.
Why does aloe dry out? From excess moisture when the root system is completely rotten. Aloe leaves dry out if the plant is planted in too heavy soil (clay-based). There is no air reaching the roots and there is a constant excess of moisture. But sometimes aloe leaves dry very quickly, without changing their previous color, that is, green aloe leaves dry. Cause: root rot. How to treat the disease? Dry rot cannot be treated, and the plant affected by it must be immediately thrown away and the pot disinfected. To prevent the appearance of dry rot, it is recommended to spray the entire collection with systemic fungicides once every six months.
Root rot often occurs due to improper care. This dangerous disease, often leading to the death of the agave. Since the plant is in a pot, it is not always possible to understand that the root system is suffering. Therefore, regular examination of aloe is necessary in order to identify alarming symptoms by external signs.
Often gardeners delay removing the plant from the pot until the very last moment, for fear of harming it. They try to change the situation with feeding or other measures, but this only makes the situation worse. There are no external signs of improvement, but the “house doctor” continues to wither away.
Signs of rotting of the plant root system
Causes of the disease
Let us remember that aloe is a succulent. In its natural environment, agave grows in arid, hot climates on sandy, well-ventilated, light soils. Violation of agricultural practices when growing succulents leads to big problems.
Frequent watering
When the soil clod is constantly moistened, the soil spreads. If the soil is heavy and clayey, a dense crust will form on the surface after drying. Since the plant breathes not only with its above-ground, but also with its underground part, it constantly releases carbon dioxide. Acidification of the soil due to waterlogging is a common consequence of this. Many nutrients are converted into forms that are not absorbed by the plant.
Heavy dampness and increased acidity soils lead to the onset of root disease development.
cramped potty
The roots of an adult plant in a tight pot are woven into a tight ring. With excessive waterlogging, the dampness inside the coma is constant, and there is almost no oxygen. At the same time, the ground may look dry from above. This difference causes the plant to experience additional stress and begin to rot inside.
Hypothermia
If you add hypothermia to excess moisture, the situation gets worse. According to statistics, the roots of succulents rot more often in autumn and winter period, when it blows strongly from the windows and the soil in the pots cools. But also in warm time years, watering with cold water harms the plant.
Infection with pathogens
Sometimes even when moderate watering The disease may develop due to a fungal infection. This happens if aloe is planted in a container in which it lived before sick plant. Some bacteria can live on the walls of an old pot for years, and as soon as a favorable situation arises for them, they will easily take over the new space.
Fertilizing with organic fertilizers
Often gardeners, trying to revive a diseased plant with fertilizing, aggravate the situation by causing a surge in the development of bacteria that provoke rot. Manure or bird droppings are especially harmful to aloe.
How to save an agave if its root system is damaged?
What to do if the aloe roots are already partially rotten? An urgent plant transplant is required.
The transplantation process consists of several steps:
Caring for a “home doctor” after a transplant
When the agave has taken root, switch to the mode of moderately moistening the soil with water at room temperature.
It is recommended to water the agave twice a month in the warm season. In autumn and winter, water aloe once a month, or even leave the plant without water until spring. Make sure that the plant is not exposed to cold or drafts.
Observing golden rule For aloe, keeping it dry is better than keeping it waterlogged, and you can enjoy the healthy appearance of your “home doctor” for a long time.
