Why do aloe leaf tips dry: common plant diseases and pests. Why do aloe leaves dry out? Dark spots appear on aloe leaves

Aloe is a type of succulent plant, and in Arabic its name means "bitter". Even in ancient times, people appreciated the benefits of this culture, and also learned how to use its juice and leaves. Such juice is considered a preventive and remedy. It is used both and. Today, aloe can be found in many houses and apartments. This popularity is due to medicinal properties culture and unpretentiousness in care. But, despite the undemanding culture, aloe diseases are far from uncommon.

Features of aloe care

So that aloe does not develop 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 put a container with a plant on a windowsill with south side. In cold weather, additional lighting is not 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 to the terrace.
Tolerates lack of moisture 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 provoke the appearance of fungal infections, and rotten leaves can also form.
The bush needs abundant watering. Between procedures, the soil should have time to dry out.

In order for plants to develop well, it is necessary to provide them nutrient soil. For this ready soil you can buy or make your own. To prevent any diseases, it is recommended to perform regular top dressing.

Common problems with aloe

Many beginners do not know why the tips of the leaves dry in different types of aloe. Most often this means that the plants have not been transplanted for a long time. At the same time, the roots occupy all the free space in the container, as a result, aloe does not receive enough useful components. Therefore, if the tips of the leaves of aloe dry, then it is urgently needed. Before transplanting, the plants are not watered to make it easier to pull out.

What to do with curled leaves

It is also important to know what to do if aloe leaves curl. Such a sign indicates that the seedling lacks normal care. It is necessary to wipe the leaves from dirt, and also sprinkle with water at least once a week.

If the plant has thin leaves, then this may be due to lack of lighting or lack of humidity.

rotten roots

But if the root is rotten, then this is evidence of the most common mistake, too abundant. If the roots are rotten, then the bush needs to be removed and the damaged parts removed, and the aloe leaves sorted out.

Each grower needs to have an idea how to save a flower if the leaves turn yellow. Most often this happens with malnutrition.

The leaves may turn yellow if you forget about top dressing. 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 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 signal that the bushes do not have enough moisture. In this case, you need to revise the scheme and irrigation periods.
If the spots are darkish and soft, then the plants are bent 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, then this indicates heavy pollution. In this case, salvation is 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, then the leaves will soon return to their color.
Other problems:
Sometimes the plant withers and dies right in front of your eyes. If the leaves begin to curl and fall, then the water for irrigation is too cold. The flower may die if the leaves turn pale and wither. This happens with too much watering.

If the tips of the leaves of any aloe dry, 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 the abundance of water in the pot. In this case, the stem begins to dry out, and the plant does not change its size. long time. To cure a flower, you need to dig it up, and then cut off all the rotten roots. The remains are sprinkled with coal powder or sulfur. Then the bush needs to be moved to a new soil. After an illness, watering should not be done for three weeks. Such a disease is difficult to treat, so sometimes the seedling has to be completely removed.

With dry rot, the bush can die imperceptibly, as the flower dries up from the inside, but outwardly this does not manifest itself in any way. For prevention, it is necessary to spray the plant with a fungicide from time to time.

Aloe pests

Also, the plant can twist, change color and weaken due to pest damage.

spider mite

The most dangerous is the spider mite. It is very difficult to notice, since its dimensions are not more than 1 mm. In this case, the sheet may become covered with white spots and a barely noticeable web may appear. At a later stage, the stems and leaves turn scarlet.

For the treatment of adversity, 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 have Brown color and look like plaques on the leaves. At the same time, the leaves dry up and curl, and red-brown spots appear.

To combat such pests, you can use a tincture of garlic, which wipes the leaves.

Mealybug

When affected by this pest, the flower is covered with a white bloom. In this case, aloe can rot. It is not difficult to deal with 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. Such care will help to avoid the appearance of a pest.

Such insects appear in humid and hot rooms. You can recognize pests by the silvery stripes on the leaves. To combat these insects, chemicals. After processing the plants, the procedure must be repeated after a week. Affected plants are best taken to another room.

Despite its hardiness and vitality, aloe requires special care. At proper care and preventive measures you can grow a beautiful and healthy plant that will decorate the apartment long years. Timely treatment of diseased or pest-affected leaves will help save the plant.

Common Reasons:

1. Overflow.

2. Overflow and Root Rotting.

3. Overdrying the earthy coma.

4. Not enough light.

5. Too much light.

And now:

1. Have you planted it in universal soil?

Or did you dug up the ground on the street?

Or bought a special soil for Succulents? (1 part peat, 10 parts sand, 1 part activated carbon).

2. Aloe loves light.

The more light, the more abundant the watering should be ("abundantly" not to be confused with "more often").

Either pour or dry

look closely at the ground.

Sometimes small creatures start up and eat the trunk at the root

Happen inside the trunk near the ground - as an option

If the plant is large and the tips turn yellow at the lower leaves, then this is a natural process of their death. If the tips turn yellow on the upper leaves and still curl into a tube, water often.

don't flood!

I observed this on aloe arborescens ("agave"), which, without care and attention, lived at my place of work for a long time. When I got carried away with flowers, I took under my wing all the "nobody's" plants, and the turn came to aloe. His leaves were rather narrow, not very fleshy, folded into a tube, turning yellow towards the ends and even with a reddish tint. Many withered away.

When I took it out of the pot, I saw that it was sitting in terrible clay, and most importantly, for so long without transplanting roots, it had grown so much that the pot had become not only cramped, but ... in general, I saw a lump of tightly wound roots almost without land already.

I transplanted it into a pot, four centimeters larger than the previous one in width and depth, and completely changed the earth to fresh, bought in a store ("universal"). I put it on the edge of a sunny windowsill. I watered not very sparingly - as the topsoil dries up and depending on the temperature. That is, it did not flood, but it did not drought either.

You have no idea how aloe came to life! It does not immediately, of course, affect, but after a while it was already a powerful succulent plant with thick, intensely green leaves, and many “children” grew from the root. (We cut the main plant for an employee who was treated with aloe juice and honey, and the children continued to grow as a cheerful bush until we gave them away.)

The cause of the malaise of aloe was prolonged absence transplants - a cramped pot, depletion and salinity of the soil, chronic lack of nutrition.

If the plant lives with a lack nutrients, it, in order to grow, is forced to take them from itself from older leaves, building new leaves from this material. Therefore, the old leaves grow thin, turn yellow, and then die off.

Different types aloes require different handling, some species are more vulnerable, they need a more thoughtful approach. And some (including the agave), on the contrary, feel better, like ordinary plants, with normal watering and in fertile soil. Aloe tree (Aloe arborescens Miller), called agave in everyday life. This photo is from the net, and ours looked even better, more massive and juicier. :)

Tatyana, in any case, you cannot do without a transplant. Do not water for a few days before transplanting to old earth easier to move away from the roots - let it dry. Remove the plant from the pot, inspect its roots, in what condition they are, if there are rotting or withered - remove, at the same time change the ground, and select a new pot according to the size of the root system, plus a little for growth.

Depending on the condition of the roots, adjust the watering: if they were rotting, then they watered excessively. When watering, it is enough to moisten only the upper layers of the soil, since the moisture in the depths lasts for a long time, especially in large pots.

Why does aloe dry? This means that the plant long time no transplant. The roots have taken up all the free space in the pot, because of this, the aloe does not get enough useful substances. He has to feed on older leaves, so the tips dry. In this case, you need.

Before transplanting, it is better not to water the plant for several days, then it will be easier to pull it out. The new pot should be free and spacious:

• if the roots have grown on the sides - you need to take a wider pot;
• if the roots grew down - the pot should be higher.

Leaves are curling

Why do aloe leaves curl? So the plant shows that it lack of care. It is necessary to wipe the leaves from dust, spray clean water once a week (twice a week in summer).

thin leaves

Why does aloe have thin leaves? Possible two reasons:

• lack of lighting - the leaves with all their might reach for the light, while stretching and thinning;
• lack of watering - the leaves do not have enough moisture, they become less juicy.

In general, aloe can be watered with two different ways- from above and through the pallet. The main thing to remember is that all the earth in the pot must be spilled properly. If you only water upper layer- the lower roots will not have enough water and nutrients. At the same time, the earth will dry out quickly, you will have to water more often - aloe can rot.

The best option is to pour water into the pan. The main roots of aloe are lower, they will take for themselves required amount water. After an hour, the remaining liquid must be drained.

Leaf tips turn yellow

Why do aloe leaves turn yellow? What to do? This usually happens with a lack of nutrition. Agave needs to be fed once a month with special fertilizers for cacti or. In winter, aloe rests, additional nutrition is not required.

Also, the leaves may turn yellow if the aloe does not have enough light. In this case, it will be enough just to rearrange the plant in a more lit place.

Spots

Depending on the type of spots on aloe and their color different problems can be diagnosed:

• brown spots indicate that aloe lacks moisture (you need to change the watering system);
• if the spots are soft and dark, the plant may be infected with a fungus (needs to be treated with an antifungal agent);
• the leaves may become covered with black spots - this means that they are very dirty (it is necessary to wipe them from dust more often).

The leaves turned red

Thus the agave only answers too bright sun, nothing to worry about.

If you move it to a more shady place, the leaves will soon return to their green color.

Wither

It happens that aloe dies right before our eyes:

• if the leaves suddenly begin to fall off - the water for irrigation is too cold (it is better to always keep water in a watering can next to aloe, then the temperature will be optimal);
• if the leaves take on an unhealthy appearance, wither and turn pale - there is too much water in the ground (irrigation must be urgently adjusted).

Diseases

Basically, aloe at home suffers from two diseases - root rot and dry rot. It is important to recognize the disease in time and have time to save the plant.

root rot

Roots start to rot from excess water in the pot. The reason is very frequent and abundant watering. You can recognize this disease by the following signs:

• the stalk of aloe dries out;
• the plant does not respond to watering;
• does not grow - for a long time, aloe does not change its size.

This disease can be tried to cure. The plant needs to be dug up, carefully cut off all rotten roots. Sprinkle the rest properly with sulfur or coal powder, then plant the aloe in a spacious pot. It's good if there is in the soil a large number sand.

After aloe root rot, it is best not to water for at least three weeks.

Even if the disease affected not only the roots, but also the leaves, you can try to save aloe. For this you need to use the method of "apical cuttings":

• the very top of aloe is cut off (about 15 cm);
• dried for at least two weeks in a dry and warm room;
• a dried cutting is planted in dry soil in a small pot and so waits for spring;
• in the spring, you need to gradually begin to water the aloe, quite a bit;
• if young green leaves appear - the plant is saved!

The rotten parts of the aloe must be thrown away along with the pot in which it grew. The disease is perfectly preserved in the ground and on the walls of dishes, so another plant may get sick.

Dry rot

Unfortunately, it is very difficult to recognize this disease in time, therefore, in most cases, aloe dies.

There is only one symptom - the plant dries from the inside, but outwardly this may not be expressed in any way.

The only way to save timely prevention.

To do this, periodically aloe must be sprayed with a fungicide (antifungal agents).

Pests

1. Shchitovki- pierce the leaves and stems of the plant, drinking the juice.

They are covered with wax shields, which is why they got their name. The shield is easy to identify - the affected aloe leaves seem to be covered with sugar syrup, shiny and sticky to the touch.

You can try to wash off the shield. To do this, you need to wipe the aloe leaves every day with plain water, once a week - with laundry soap.

If there are too many scale insects, ordinary wiping may not save. Then it is better to treat aloe with special chemicals. First you need to properly spray the plant with the preparation, then dilute the remnants of the product with water and pour over the aloe.

To prevent the appearance of scale insects, you can spray aloe with diluted vinegar. Also, vinegar will help at the very beginning of the lesion, when there are few scale insects on the plant - you need to wipe off the individuals and larvae with a cotton pad dipped in vinegar.

2. spider mite.

It cannot be seen with the naked eye due to small size. The only sign is the leaves covered with cobwebs. It is important that the tick easily and quickly passes to neighboring plants, affecting them as well.

To combat spider mites on aloe, you can use alcohol solution or garlic tincture - spray plants with them. You can also use acaricides - special chemicals against ticks. For prevention, you can spray aloe cold water- the tick does not tolerate it. Naturally, this can only be done in the warm season.

At the first signs spider mite on aloe, you must immediately place the plant separately from others, best of all in a well-ventilated area (for example, on a balcony).

3. Mealybugs- also suck the juice from aloe; unlike ticks, mealybugs can be seen without a magnifying glass.

In addition, they leave traces of their crime on the aloe - white pieces that look like fluff or cotton wool.

Can fight folk remedies, for example, wipe the affected areas with garlic tincture. For cooking, you need to chop a few cloves of garlic and soak them in alcohol for a while.

If the plant is affected too much, you will have to use chemicals.

4. thrips- Insects that live best in hot and humid areas.

It is not difficult to determine the defeat of thrips - silvery stripes appear on the aloe, which the pests leave behind when moving.

To combat thrips, only chemical agents can be used. It is important that these pests quickly acquire immunity to the drugs used, so the substances can be combined - for example, spray one and water the other.

After processing aloe from thrips, you need to withstand a week and repeat the procedure. This will help get rid of the larvae and surviving individuals. In order not to infect neighboring plants, it is better to move the affected aloe to an isolator.

When transferring aloe to another place and during processing, care must be taken - thrips larvae fall and thus fall on other plants.

Basically, all pests feed on aloe juice, which leads to a slowdown in its growth.

Hello Lyuba!

The most common rookie mistake is over watering plants. A lot of moisture leads to rotting of the roots, the leaves become soft and change color. Also, the problem may be inappropriate soil, lack or excess of lighting. Aloe loves bright sunlight, but not scorching rays.

It is believed that the southern windows are quite appropriate place in order for the plant to feel good. But during the heat, it must be protected. After winter, on the south window, the agave is shaded with gauze or a mosquito net, after a couple of weeks it is removed. Quite tolerably, it grows both in the western and north windows. For the summer, if possible, the pet is taken out to Fresh air- to the garden or balcony.

Salvation of aloe after overflow

If aloe is flooded, but the roots are only partially rotted, it can be saved:

• Remove the root ball from the pot.
• Cut off all rotten roots.
• Sprinkle slices charcoal. If you don't have it at home, buy it at the pharmacy Activated carbon and grind it to powder.
• Use a smaller pot for transplanting.
• Provide the plant with good drainage.
• Sprinkle healthy roots with fresh, moist substrate.
• After transplanting a pet, do not water it for several days.
• Then water sparingly and very sparingly.

If the roots are rotten, you can try to root the apical cutting:

• Dry the cut.
• Place the cutting in wet sand or fine expanded clay.
• Alternative: Place the cutting in a tall, narrow vase without water for one flower. After a while, the plant will take root (it is convenient to observe the process if the vase is glass). And it can be planted in suitable soil.

soil for aloe

• AT natural conditions the plant thrives on sandy soil. At home cultivation you need to provide it with a mixture that is well permeable to both air and water. Also, the mixture should be fertile, and sufficient drainage should be put in the pot. When preparing the soil for aloe, mix sod, leaf and humus soil, add clay soil and sand.
• It is important to transplant the agave in the spring after the end of the dormant period. AT clay pot place a drainage consisting of pebbles and shards. The drainage is sprinkled with sand and half of the pot is filled with the prepared soil mixture. If diseased roots are cut off from the plant, then the sections are sprinkled with charcoal for disinfection.
• young plant should be freed from the old soil. The roots are carefully spread in containers, sprinkled with prepared soil and gently squeezed so that the bush is in better contact with the ground. There should be a distance of about 2 cm from the edge of the pot to the soil. After the planting is completed, the plant can be carefully watered along the edge of the pot (if this is a planned transplant, and not because the aloe dies from frequent watering). Until the aloe reaches the age of 3 or 4 years, it must be transplanted every year. Adult specimens are transplanted every 2 or 3 years.

• Even in summer, watering should be moderate. Showing warmth and sun. The more heat, the more plant needs the sun.
• Too much sunny place requires the pot to be covered protective screen. In strong sun, the roots can overheat, and this is great harm for a plant.
• A very lit area is bad for aloe, especially if you have just acquired it or have recently planted it. Also, too much light will adversely affect a weakened plant, a very young specimen, or if it has not had time to take root.

Sincerely, Galina.

The main diseases can be: root rot and dry rot.

root rot

Usually the defeat occurs when the soil moisture is too high. Aloe can be saved only with early diagnosis of the disease.

External signs diseases:

• Root rot
• dry stem
• does not respond to watering.

Control measures
If the roots rot only partially, you need to remove all the affected parts of the roots, and sprinkle the rest well with coal powder or sulfur, and then plant them in fresh soil with a large proportion of sand. After two to three weeks, water very carefully. If the roots are completely rotted, then you can save at least upper part stem, making a cutting out of it. It is necessary to cut off part of the stem so that only healthy tissue remains.

If your plant is completely infested, throw it away with the pot, as the fungus can survive in the soil for years.

Dry rot

The disease occurs when the plant is improperly maintained.

External signs

Outwardly, this is not visible, while rot does not appear. The plant simply dries out, without noticeably changing color and shape, but it turns out to be completely dry inside. Moreover, all this happens very quickly, which usually does not have time to notice the initial period.

Control measures
Since this disease proceeds too quickly and methods of dealing with it have not yet been invented, the plant dies. But you can prevent the disease by periodically doing preventive spraying with a systemic fungicide.
