Why do trees dry out in autumn
Why do trees dry in the garden? Analysis of the reasons why the apple tree has withered
. The first spray is carried out in the flowering phase of the fruit buds, the next at an interval of 7-10 days.
Ripe fruits are best eaten immediately as they are poorly stored. For processing or transportation, cherries are harvested to full maturity once they have reached their maximum size and are almost completely painted.
The average ripening time for cherries is 10 days, but the fruit can remain on branches for a long time.
For many beginning gardeners, the problem of cutting cherries leads to a condition that is close to stupidity. The questions begin immediately: Are the cherries cutting? Trees seem to bloom well without them. And if, after abundant flowering, the harvest was not very good, then gardeners, without hesitation, explain this by saying that among the flowers there were a lot of empty flowers, but is that so?
By the way, the July cyclone provoked the appearance of gray rot both in some varieties of roses (buds without opening, rotten) and in individual lilies, in which the stems and leaves turned yellow.
This time I had to pay a visit to understand everything on site. When I looked at the dried berries in the bushes, I immediately realized what was going on. The harvest was ruined by the gray rot caused by the July cyclone. This disease has "stolen" a large part of the harvest from gardeners in many strawberry beds. The disease was very severe and almost permanent - all ovaries were affected in the earliest stages, so the berries did not rot, but were dried without being watered.
- Before processing, it is recommended to wash the tree in the shower. After this process, most of the insect is washed off. The day after the soap treatment, the remaining soap is washed off in the shower. After 2-3 days, a new treatment is carried out. For the complete destruction of the spider mite, 3 treatments of the tree with a soap solution must be carried out. The place where the affected tangerine stood was washed thoroughly.
- Very often you can observe mandarin leaves falling off, but this phenomenon does not always indicate a disease of the plant. A tree can shed its leaves during the dormant period, which usually lasts from late October to mid-February. In this case, you need to put the tree in a cool room with a temperature of 14-17 ° C and reduce the amount of watering.

It's hard to imagine that an apple tree doesn't grow on a piece of land, even a tiny one. If the area is fruit tree-friendly, apple orchards become a source of income. But wherever this beautiful tree grows, disease can overtake it. Why does the apple tree turn black and dry, why does the tree dry up and what to do? There are questions that have an answer.
It is not surprising that felt cherries are particularly affected by moniliosis, which is grown in regions with high humidity: in the Far East, in the north and west of the Black Earth region, in the non-Chernozem region and in the southwest of the North Caucasus.
Felt cherries increase appetite, improve digestion, they are eaten fresh, they make delicious jam, jam, jam, lozenge, compote, wine, juice.
Not at all. The fact is that the buds are simple and either blooming or leafy. In this case, flower buds awaken much earlier than foliage, creating the illusion of a crown completely covered in flowers.
- Olga Nikolaevna herself saw how she picked up a whole plate of ripe berries with her. What to answer because the locations are almost nearby. The development of gray rot is influenced by various factors. This is a note (there are more stable ones, for example
- Sometimes the tangerine stays dry and then crumbles. If a dry brown crust has formed on the edges of the leaf plate, this is due to an excess of moisture in the soil. In this case, the tree should be transplanted into fresh, breathable soil with mostly leafy soil and good drainage. If rotten roots are found during the transplant, they will need to be removed.
- Leaves can fall if the air is too dry. This can be observed in summer and during the heating season. In this case, the crown should be sprayed daily and a container of water should be placed near the pot to moisten the air near the tree.
In spring, after the young leaves have bloomed, oily spots appear on the young leaves. That's scab on the apple tree. Over time, the upper parts will be covered with velvet, then the entire plate will turn brown. Therefore, the apple trees not only turn black and dry in midsummer, but the fruits are also affected by the disease and can no longer be fed.
- The garden only attracts glances, admired when it is healthy. And the fact that it is easier to prevent a disease than it is to cure it applies not only to a person but to their green friends as well. From the beginning it is necessary to control the development of the apple trees.

Experienced gardeners may find that caring for cherries and pruning them are two different things, as removing branches will lead to sticking that will later damage the plant. Such a scenario is quite real when it is severely weakened. But if the tree is healthy and not frozen in winter, the right pruning of cherries will only help it.

Often times, citrus leaves dry out due to a lack of moisture. Revitalize a diseased plant as follows. Place the pot in a basin with water at room temperature so that the water flushes with the edge of the pot. After that, the soil must be watered from above. When the soil is completely damp and has stopped bubbling, drain off any excess water. Then spray the tree with Epin at the rate of 1 ml per 2 liters of water. Spraying is done 2 times a week. This method can also be used to revive a very dried plant.
Incorrect transplantation can also cause leaves to fall if the root neck is buried in the ground or if the citrus fruits are planted in an oversized pot. It is necessary to eliminate these shortcomings and observe the plant. If the leaf fall hasn't stopped, then you should look for another reason.
The treatments are repeated every 2 weeks until the end of the season.
Tangerine leaves turn yellow
Scab is a fungal disease. Its spores overwinter on last year's foliage and are introduced into the plant along a green cone since young leaves appear. The prerequisite for the implementation is the slow opening of the leaf and warm rainy weather. Under such conditions, the introduced spores germinate and form a mycelium. The scab more often affects old trees with a thickened, poorly blown crown. The disease, after it develops, mainly destroys the leaves, they turn black and fall off. Fruits are ugly or fall off after being thrown.
When buying a seedling, care should be taken to ensure that the root system is well developed and there are no mold spots on the roots, the surface color is uniform. The location of the vaccination is recognizable. The stem is uniform in color, the bark is not damaged. Cleaning the leaves of fallen trees in the fall prevents the spread of spores and other infections. It is best to burn the leaves of the autumn garden, then use the ashes as fertilizer.
Why is tangerine yellow
With total moniliosis one cannot wait for the harvest. When the disease begins and the fungus can destroy the tree from year to year, sooner or later the felt cherry dries up.
The recognition of felt cherries, especially in the Central Plateau, was significantly delayed. In recent years, however, many gardeners have started to grow this culture here, mainly because of its early maturity, in order to spoil their children and grandchildren with sweet fruits as soon as possible.
Tangerine leaves dry
Cherries should be planted, cared for and cut according to a well thought-out scheme, without gravity allowing them to grow. Despite the difference between bushy and tree-like species, flower buds mainly form on annual branches. In addition, when the annual growth is 0.5 m or more, the buds are vegetative and new branches will form from them. In contrast, shoots that are too short are strewn with blooming buds. Both options are unsuitable, so the gardener must artificially adjust the length of the growth in the range of 0.25-0.5 meters. Only such growths will bear fruit this year and lay the basis for a good harvest next year.
Plants can suffer from frost and die.
Etc.) and growing conditions. In particular, care should be taken to ensure that plantings are thickened and abundantly sprinkled with nitrogen, which will weaken the immunity of plants.
Why do strawberries make dry berries in the garden?
Many mandarin diseases develop due to improper care and a lack of trace elements in the soil. In order to grow a healthy, fruit-bearing tree, it is important to maintain this tropical culture under the conditions usual for it, monitor the smallest external changes and take timely measures to eradicate diseases.
Quite often the fall of tangerine leaves leads to a lack of potassium in the soil. Potassium nitrate is used as a fertilizer to compensate.
To prevent this terrible and difficult to remove fungal disease, a number of rules should be followed:
The fight against fungal diseases consists in the observation of agricultural engineering by spraying several times with fungicides based on copper or their substitutes. All treatments are canceled 3 weeks before harvest.
Trimming and crown shaping should only be done with a disinfected tool and close wounds immediately after infection has penetrated. A photo of the disease of the leaves of the apple tree and its treatment shows the danger of non-compliance with the requirements of hygiene. In the spring, two treatments with fungicides with kidney swelling and green cone should be carried out. For mature trees, top-dressing and mulching of the trunk circle are required in good time.
(2 g / 10 l water). Spraying during the growing season: the first - before flowering, the following - with an interval of 7-10 days. A.
And why didn't a neighbor have strawberries?
In gardens in the lowlands, in places where a lot of snow accumulates in winter and often thaws in winter, plants often suffer from damage to the cortex of the lower part of the trunks, that is, the root neck is warmed. Defeat is possible by single flocks or by a continuous ring. In the spring, the cherry begins to bloom normally, but then it gets sick and dries up. Doctor S.-h. of the sciencesSometimes it suddenly turns out, in the middle of a growing season that normally begins, that the cherry has dried out after flowering. Why is the cherry drying out because yesterday nothing predicted such a nuisance? This is due to a dangerous fungal disease of cherry moniliosis or a monilial burn that can dry out the branches of the cherry and cause the entire tree to die. Young leaves, flowers, ovaries, shoot tips dry out, and the branches look like after a fire - these are the first symptoms of the disease, reminiscent of the effects of fire or frost. Then small gray growths appear on the cortex, the fruits of cherry rot and fall, covered with randomly arranged gray growths - gray rot. The branches are covered with cracks, and chewing gum sticks out and cracks on them, and they die. Cut off the dried areas of the branches, grab some healthy tissue, collect and destroy any affected fruit, and treat the tree with oleocoprit, captan, cuprosan, or some other fungicide. Spraying cherries with Bordeaux liquid or copper chloroxide while the leaves are already blooming on the cherry can cause burns. To combat moniliosis, you need to do more than one treatment of cherries with fungicides. However, unless you wait for the cherry to get sick and treat garden trees preventively against diseases and pests, you don't have to worry about the health of the trees and the quality of the harvest.
What to do with wild strawberries
In addition, in early spring, some gardeners try to make a thick layer of sawdust under the canopy of fruit trees. Such a layer delays the melting of the snow, contributes to the accumulation of moisture, but at the same time wakes the crown to grow, and the root system in frozen ground does not provide the above-ground part with food and water in a timely manner. The physiological drying of the crown takes place. Therefore, meltwater must be diverted from the crowns of the fruit trees, as the roots can warm up during their stagnation. Sawdust can be used to catch snow, but only in places where the perennial root system is not located.
All affected berries from the beds must be collected and destroyed (buried in the ground outside the site). Sheets are now desirable to cut and spray the beds with a 1% Bordeaux mixture. Dig up the passages and introduce complex mineral fertilizers.
And now what to do with these bushes - abandon them or throw them away?
In addition, the leaves turn yellow and fall into the room with drafts, excessive soil moisture, lack of light.
The proximity of coniferous and fruit trees in the immediate vicinity should not be permitted.
Another terrifying fungal disease is rust. This disease manifests itself after the apple tree has blossomed. Orange spots appear on the leaves of the tree on top of the plate. In the places there are black dots, underneath there are sacs of spores that open and shoot with spores. The lower part of the leaf also has a yellow spot at this point. In the future, the disease progresses, as can be seen in the photo. Diseases of the leaves of apple trees and their treatment require patience.
Only with proper care will the tree stay healthy and enjoy decorativeness and harvest. Strict adherence to agricultural technology is the key to a healthy garden.
Why do fruit trees dry out in spring?
Be careful when using crop protection products. Always read the label instructions and drug information before use. Carry out the processing in compliance with all safety regulations. Remember: you can only harvest and consume products 20 or even better 30 days after the last chemical treatment.
And to protect them from rabbits and mice, which can completely destroy plantings, poisoned baits are laid out, the trunks at the base are covered with a net.
Why does the cherry turn yellow? This symptom can be observed with a lack of nitrogen or boron in the soil, with the difference that with a lack of boron the cherry leaves not only turn yellow, but also deform from the upper young shoots and the veins on the leaf plate turn red. Nitrogen-starved trees turn yellow from the lower shoots, their leaves become smaller and sometimes fall. Check the relevant section of the article for how, when, and how to feed cherries so that they are not lacking in nutrients. Cherry leaves turn yellow due to the moniliosis, while the branches dry out.In the same way, the fungal disease coccomycosis manifests itself, which you need to get rid of in the same way as in moniliosis. Sometimes ants become the cause of yellow leaves, and if there is an anthill in your yard then you are preparing for big problems. The leaves turn yellow because they weren't properly watered and the cherry was frozen in winter. Sometimes mushrooms or tinder fungi grow in the lower part of the cherry stem, which will likely kill the tree if you don't control them.
Fruit trees can dry out in the spring as they cannot withstand the winter frost. It is recommended to water fruit trees abundantly with water in the fall, especially if the fall was not rainy. In dry soils, the roots freeze faster and die off.
And in early spring, even before the young leaves grow, the beds need to be cleaned of old leaves and mustaches - the main source of winter infections, and straw beds should be removed. After that, spray the bushes with 2-3% Bordeaux liquid. Loosen the dried soil, sprinkle with fresh humus.
Tata all red
A good friend of mine came to me at the end of June with such questions. At that time, garden strawberries began to ripen in our Nizhny Novgorod region. And before that, in June, there was heat for more than two weeks without a single rain. And that's while berries are being loaded! My hands didn't reach me to water strawberry beds. As soon as I saw that the leaves near the bushes were fading and small berries were forming, I immediately started watering.
Many gardeners are faced with the fact that tangerine leaves turn yellow. Usually the reason is a lack of minerals. If there is a lack of nitrogen, the lower leaves of the citrus fruits initially turn yellow, and the rest gradually. To replenish the nitrogen in the soil, nitrogen fertilizers are used, for example ammonium nitrate or ammonium sulfate or organic fertilizers. With iron deficiency, the leaf plate turns light yellow, the disease develops chlorosis. Chlorosis first covers young leaves and then spreads to old ones. To prevent this disease, the plant is treated with iron chelate once a month.
In early spring, before the sap begins to flow, look for the affected areas, clean them to healthy wood, treat them with a strong solution of 5 grams of copper sulphate in half a glass of boiling water (5%);
In addition to leaves, rust also affects the fruits and branches of a tree in a neglected state. The fungus initially develops on juniper and later, after overwintering, falls on plant remains on a leaf of a tree.
When all measures have been completed, the apple tree can become ill in rare, particularly unfavorable years. Knowing the signs of the disease, the examination will allow you to understand the reason for the yellowing of the foliage on the apple tree.

Moniliosis of cherries.
The most popular varieties of felt cherries are - Alice, Amurka, Delight, Summer and many others. Every gardener can choose the variety that is best for their garden setting.
Cherry turns yellow.
Two three-year-old felt cherries grow in my garden. Last spring they bloomed beautifully and even gave several berries, but in the middle of summer suddenly a cherry began to dry up, first the leaves turned brown, and then the branches. I have regularly watered, fed and insulated plants for the winter. Advice on what to do with dried cherries and how to protect another nearby crop? L. Shcherbakova
Why does cherry fall when summer is in the yard? As a rule, this occurs after the leaves have turned yellow and is the development of a painful process that was not recognized in time. Analyze and determine what caused the disease - moniliosis, cocomycosis or some other disease, lack of food, moisture, pest infestation or damage to the cherry roots.
Cherry does not bear fruit.
And maybe you also need to get rid of various pests that can eat the roots of fruit trees. The most famous pest, at least for me, is the bear. Therefore, it is good to cultivate the soil near the root of the fruit tree with a little anti-medicinal liquid before winter, and spray the bushes with a solution of potassium permanganate of dark pink color or 1% Bordeaux liquid before flowering. When ovaries appear, you can cultivate the soil to prevent the development of gray rot by pouring ash (2 glasses of ash per bucket of water), a solution of calcium chloride (100 g per bucket of water) or dusting with ash on the bottom of the bushes.
That's why I suggested that. The berries may have dried out due to a severe lack of moisture in the soil. I advised you over the phone not to touch the bushes unless they are old and their foliage is healthy.
The yellowing of a plate can be promoted by insufficient lighting or too close to a pot. The problem can be solved by transplanting the plant into a larger pot with fresh nutrient medium.
After repeated treatment with fungicides, coat with garden varnish or special spatula for prevention.
Therefore, juniper in the garden often has to be treated against fungal diseases without visible traces of rust.
The apple tree gets food from roots and leaves. If a disease of any part of the tree is left untreated, it will result in death. Why the apple tree dries up and what needs to be done can be determined on site. There are several diseases that are transmitted:
You can check out other articles on our website When the ends of the branches on bush cherries become bare, the number of shoots decreases, and the remaining ones are shortened by a third of the length. Skeletal and semi-skeletal branches are also subject to shortening. As a rule, they are cut into upwardly growing, trained side branches. Experienced gardeners recommend alternating the shortening of the skeletal rung with the shortening of the half-skeletal rung within a year. Then the cherry will give a good harvest.
According to the description, your felt cherry is suffering from moniliosis, a dangerous fungal disease. During flowering, the fungal spores are carried by the wind and fall onto the flowers. First, the flowers, ovaries, shoot tips and leaves dry out. Subsequently, the conductive vessels of the branches are affected, after which they dry out.
Felt cherries are unusually polymorphic.
Well, as already indicated here, you can sprinkle a hole with fruit tree with sawdust or straw to trap moisture.
To begin the process of tying berries, on both sides of the row, put clean straw or shavings, conifers so that stalks and berries do not touch the ground.
But two weeks later the doorbell rang again, and Olga Nikolaevna asked again, worried: what should she do with the strawberry bushes?
Another reason tangerine yellow can be a spider mite invasion. The pest attacks the leaf plate and sucks the juices out of the plant, causing the leaves to turn yellow and fall. To see a spider mite, a magnifying glass should be used. If this pest is present, wipe the plant with a soapy solution.
Rich harvests and a healthy garden! Read why the apple tree leaves turn yellow!
Rust can cause the leaves of the apple tree to turn yellow. It also causes fruit to fall and break the bark on the trunk. At the first sign of rust, they begin to struggle with it. All infected leaves, shoots, fruits are removed immediately. Branches are cut a few centimeters below the infection site. Spray with one of the drugs:
“Why don't the trees that lived on the site for years bloom and dry? Why did plums and cherries bloom, but suddenly wither and wither? What about the evergreen rhododendrons (photo on the left. Grown without problems for 10 years) and conifers? Where did the strange spots on the leaves suddenly come from? “, You ask us excitedly and send us lots of photos with dried branches, wounds on the trunks, twisted leaves, etc. What can I say, many wild trees (e.g. birches) that have now dried out are not in the forests more flowered. Look, part of the birch trees are covered by July 1st (1), and a very large number (for example 2) have dried up. And such infected plants are around 30 percent in places! When was this I am closely watching these things, but before that it was not.
Here (on the right in the photo) there is a cherry without leaves, which previously bears fruit for about 15 years. What's happening?
I explain briefly: The last two summers have been inferior. Eternal rain and +12 did not give the plants the opportunity to properly spend the warm season: gain green mass, collect nutrients for the future, strengthen immunity to diseases and pests, and also strengthen the bark for a difficult wintering. Due to the abundance of rain, many logs tore and harmful fungal spores got there. These fungal diseases, which used to be easy to overcome, were now buried in trunks and branches and began their destructive work.
Then, after the cold and wet summer of 16, came a restless winter. In December all the snow melted (!) And two weeks of frost from -25 to -35 degrees froze the ground by almost half a meter! It should be noted that in winter, under the snow, we always have approximately zero, the ground does not freeze (and, if necessary, can even be easily dug up). Roots are in such a moisture-permeable environment and “drink” water all winter long (like conifers and rhododendrons). Standing in the frozen ground, they simply dried out quietly under the influence of wind and sun and could only be helped by covering a dense upholstery fabric.
The long, very cold spring of 17 years did not give the plants any strength, but took them away. Therefore, in the summer they met either dead or dried up.
What are we urgently doing:
- To wake the living, but to sleep, the roots are showered with hot water at 50 degrees with a spoon of nitrogen (urea, urea and the like) on a watering can of 5 to 7 liters.
- All injured people can be sprayed once with “Epin” - a good stimulant (just don't get carried away, or you will plant the plants like medicine), and spill “Kornevin” along the roots, allowing the affected root system to grow new roots .
- Spray antifungal drugs on all fruit trees (at least once a month) (there are many, you can use others, just do not pour Bordeaux liquid on the leaves, burn them!).
- Have aphid products (such as Iskra-Bio or others) ready and destroy pests that have arrived on time.
- From spring to mid-summer we feed plants with nitrogen fertilizer or distribute manure in a circle close to the stem. Plants starve on our poor soils.
- We give complex fertilizers (we use Fertik).
- After midsummer, the nitrogen fertilization is eliminated by liquid manure and the plants are strengthened with potassium-phosphorus fertilizers. Otherwise, your plants will not stop growing, will not harden in winter, and will die easily.
- From all kinds of spots on the leaves, powdery mildew (on phlox, gooseberries, red maple, roses. When clematis began to fade, strange spots appeared on the bushes, etc.) we use a mixture of Maxim + Topaz preparations. Read the instructions, boldly mix and sprinkle the leaves and needles with the plants, not afraid of the bright red color of the solution. After drying, the plants are not noticeably colored, but are protected from fungus.
The climate is changing, we have to be prepared that some plants will no longer survive with us. For example, plums die off massively in our area and stone junipers, for example, which were not killed before, can now easily "burn", etc.
We will adapt, learn to live in new conditions and try to help the plants and gardens that surround us to survive. You just have to pay more attention to what surrounds us and not be lazy!
Unfortunately, gardeners often see a rather gloomy picture. On the apple tree, the leaves suddenly seem to turn yellow, dry and fall off for no reason. The fruit tree, which until recently had a lush green crown, is literally withering before our eyes. It is important not to miss the time, correctly identify the cause and help the apple tree. This article explains what factors can cause foliage and twigs to dry out and how to get rid of them.
However, if the problem has occurred and you observe fading leaves, the first thing to do is to determine the causes of this phenomenon. And there are a lot of them.
The factors due to which the apple tree dries can be divided into several groups:
- neglect of agricultural engineering, improper care of the fruit tree;
- attacks by insect pests;
- disease damage;
- lack of trace elements, insufficient or early feeding.
Failed to exit
Many novice gardeners and summer residents consider the apple tree to be a very unpretentious culture. The main thing is that the seedlings take root, and then things will go by themselves. This point of view is fundamentally wrong.
Of course, there are wild varieties of this tree that grow in forests and fields without being tended to.However, the fruits of such "free" apple trees do not differ in good taste. The apples on them are very small, sour, astringent.
"Domesticated" apple trees were mainly bred to obtain a harvest of a certain quality. Therefore, the tree spends a lot of energy on the formation of fruits.
And the care of the garden fruit culture requires very competent and attentive work throughout the life of the tree.
What mistakes in leaving can lead to the fact that the apple tree literally dries in front of our eyes:
- In regions with frosty winters, the fruit tree should be prepared accordingly. If the plant trunk is not wrapped and protected from frost, there is a risk of so-called frost cracks forming. They arise because the moisture constantly contained in the wood fibers freezes and expands in volume. As a result, the capillaries of the trunk and the fibers of the cortex are damaged or torn.
In severe frost, the surface roots of the fruit tree can also be damaged.
It is often the freezing of the roots and the trunk that suddenly allows the previously strong and healthy apple tree to dry out after the winter.
- Unsuitable soil can lead to the fruit tree gradually drying out. In this case, individual branches begin to wither and die, and then all the leaves fall from the tree. Apple trees do not tolerate sandy and loamy soils. It is also undesirable to plant a tree in the ground with a high percentage of gravel and gravel.
- The apple tree's root system can suffer from excessive soil moisture or dense groundwater penetration. In this case, the oxygen supply to the root system is interrupted. Constantly increasing humidity also leads to the rotting of the tree roots. In such conditions, the apple tree significantly weakens, practically stops growing, actively loses its foliage.
- When planting a seedling, you need to consider in advance what plants and crops the growing apple tree will be adjacent to. Root competition is often the main cause of poor development or drying out of a tree.
In an adult apple tree, the roots are about twice as wide as the crown in diameter. Therefore, if other mature and vigorous trees are growing in close proximity, the apple tree may simply not have enough food.
- Also in the root zone, weeds and herbs should be thinned out or completely removed on a regular basis. Plants like wheatgrass and timothy are toxic to the apple tree. You definitely need to get rid of it.
- It is important to note the timing of planting seedlings. Landing takes place in autumn or spring in a landing pit prepared for winter. Young trees that were planted in summer have a very low survival rate. The twigs and tip of the "summer" seedling quickly turn yellow.
- Excessive care and the use of chemicals that go beyond the norm lead to chemical burns on various parts of the tree.Very frequent and unreasonable treatments with pesticides and insecticides are of no benefit to the tree. The apple tree itself begins to suffer from aggressive substances: its leaves, its trunk, its bark and its shoots.
- Incorrect pruning can weaken the fruit tree. Particular attention should be paid to the processing of slices. Neglect of this procedure leads to infection of the culture with disease, damage to the fungus and putrefaction.
- The cause of partial or complete dehydration of the apple tree can also be an incorrectly carried out inoculation. This process requires some experience and skill. It is good to study all its nuances before inoculating a fruit crop yourself.
- Leaves can dry out from long hot weather and dry air. The influence of this weather factor is particularly noticeable when the apple tree is still young. Usually only foliage reacts to dry air and the branches do not dry out.
Diseases and pests
Harmful insects and various diseases often settle in gardens and damage plants. Apple trees in this category of negative factors also have many enemies. First, very young trees that don't have time to get really stronger suffer. Age-related, weakened apple trees are also at risk.
Take a good look at the fruit trees in the garden.In addition to the drying up of leaves and twigs, each disease or pest has a number of specific characteristics. Accurately determining the cause of the tree's drying out will help take the necessary measures and save the apple tree.
A very common and insidious disease is cytosporosis. The disease mainly affects mature or old trees with thick bark on the trunk and branches.
A characteristic sign of cytosporosis is the drying out of individual cortex sections, the rapid drying out of the branches. In various places on the tree, including the fruit, dark formations appear in the form of tubercles and dry growths.
When a young apple tree is affected, the cytosporosis is barely noticeable for a long time. Unfortunately, the disease often results in the death of a tree if the tissue damage is too deep.
Another terrible disease that has a tremendous name is black cancer.The disease is considered incurable, the only way to extend the life of the tree is to timely remove the affected parts.
At the initial stage, the disease manifests itself in the formation of many black spots on leaf plates. After a while, branches and large appendages begin to dry out. Multiple extensive black ulcers on the trunk and bark of the branches suggest a serious and neglected extent of the disease. Rot develops on the apple tree, as a result of which the tree soon dies.
Scab often affects fruit crops. Brown and brown spots appear on the leaves, over time the leaves dry up and fall off.
If there is a gray or white bloom with dark spots on the buds and leaves, it is a sure sign of powdery mildew infection.
Fungal diseases affect foliage, bark, young shoots, buds and fruits of apple trees. If the disease began to actively develop during the flowering phase, most of the color and ovaries will dry out and fall off.
The period of greatest activity of this fungal microorganism is at the beginning of June. At this point in time, the flow of sap in the tree is still quite active, a young, juicy shoot is developing.
Pest insects are also common unwanted guests in the garden. Their livelihood damages the plantations significantly and leads to the loss or a significant reduction in the amount of crops.
- Gluttonous aphidactively eats young leaves and shoots. This insect is in tandem with ants. The latter feed on sugary liquid that aphids secrete in the course of life. Therefore, ants often carry larvae and adult insects closer to the location of the anthill. In the future, tough ants tirelessly climb the trunk to collect the nutritional composition from the bodies of these pests. Outwardly, the aphid looks like very small, elongated green rashes. It does not attack the branches and trunk, but rather settles on young leaves, sucks juices out of them and actively lays eggs.
With an extensive defeat of the crown, the tree is greatly weakened, the growth of young green branches stops, the foliage turns yellow.
- Caterpillars love to enjoy the leaves and fruits of apple trees. Notice them with the naked eye too. There are a large number of species of this insect. The main task in the fight against them is the destruction of adult individuals and larvae on the crown.
- LeafletIf you attack apple trees and actively reproduce, the foliage will gradually be destroyed. A sign of defeat by this pest is primarily a darkening of the leaves on one side or on the edge. Then the leaves curl into a tube, completely darken and fall off. In a cocoon made of a corrugated sheet, the insect actively lays larvae and moves to a healthy shoot.
- The appearance of a network of branches and leaves is a signal that the tree has attacked Mark with a cross. The insect itself is very difficult to see. Yellowed and falling leaves will tell about his further activities.
- Cockchafer larvaelive in soil and forage, including young plant roots. If they settle in the ground under an apple tree, young, growing roots are likely to be actively eating them. Normally, the apple tree blooms when the cockchafer larvae are infested in spring. However, after the color collapsed and almost all of the leaves turned yellow in July and August.
In addition to insects, some animals that dig holes and passages in the upper layers of the soil can harm the apple tree. For example, moles or mice can damage young roots of trees, weakening the entire plant.
Their presence on the site can be judged by the presence of minks, mounds of earth, and areas of loose soil.
Lack of food
The final negative factor that weakens fruit trees is a lack of essential nutrients. This can be due to the nature of the soil, insufficient or early feeding. Or it is due to the introduction into the soil of not at all the substances that are necessary for the fruit harvest.
Apple trees in particular react strongly to a lack of sulfur, magnesium and iron. The last element is especially important for the development of young seedlings. Soluble complex fertilizers are used for repeated feeding per season. The use of ammonia fertilizers significantly strengthens the immunity of the fruit tree. Nitrogen-containing drugs stimulate the development of the root system. It is also important to combine root and leaf dressings.
How do I save a tree?
A number of measures to save the tree depend on the specific reasons that led to the yellowing, drying out of the leaves, drying out of the branches and bark.
If there are serious mistakes in cultivation, you should immediately care for the crop properly.
Great attention should be paid to preparing the trees for wintering. To protect the apple tree from freezing, copious mulching of the root zone is carried out in late autumn. The trunk is wrapped with spruce branches or covering material. After the snow falls, a snowdrift is thrown around the trunk. All of these measures will avoid the deadly consequences of severe frosts.
Hygienic pruning of branches should be done regularly. An important point in this process is the timely and proper processing of all cuts.
With excessive soil moisture, you will need to resort to a seedling transplant or drain the soil. If hot, dry weather persists for a long time, it is important to water the fruit tree regularly. Do not allow herbs and weeds to grow in the zone near the trunk. Regular weeding and loosening of the soil significantly strengthens the tree and contributes to more active growth and development.
When rodents attack the root system, special poisons are used.
Few will argue that problems are better to prevent than to untangle their consequences. This approach is perfectly justified when it comes to caring for fruit crops. Feasible and timely preventive measures increase the chances that the apple trees in the garden will remain intact, strong, and get a good harvest. And, as you can see, this is the most optimal and most desired option.
Fallen leaves, branches, fruits should not remain under the apple tree. The area near the trunk should be cleaned of vegetable residues. During the treatment of diseases, all affected areas of the tree should be removed. For black cancer, this is the only way to fight the disease.
Cut and sawn branches, leaves and infested fruits should be removed from the construction site or burned as soon as possible.
The tool that was used to remove infected parts of the tree should be cleaned up. You can treat it on fire with chlorhexidine or calcin.
Birds can be very helpful in controlling insect pests. It will be useful to place a couple of birdhouses on the garden plot. Bird feeders can be equipped in winter. It is necessary to timely remove dead bark from a tree trunk. Insects often settle in the crevices and cracks between the dried areas, and rot or fungus forms.
An important preventive measure is treatment of the crown with copper preparations, a Bordeaux mixture and complex broad-spectrum insecticides. Do not forget to feed fruit trees regularly and in a timely manner.
In the first stages, when you have mastered the process of gardening, it is very difficult to understand all the nuances and tricks. The following are some tips for those who started gardening not long ago and don't have enough experience on the matter.
- If there is clear evidence that the apple tree was frozen in the winter cold, you can help it "thaw" it. To do this, gardeners water the tree with warm water with dissolved micronutrients. Set the cut aside until the buds open. Often the branches that seemed dead are still awakened. If the kidneys have not formed, the branches must be removed.
- If there is a lot of groundwater on the plantation site and the tree cannot be transplanted, you can keep the dwarf size. In this way it will be possible to save the apple tree and at the same time relieve the weakened root system.
- After a winter with severe frost, the apple tree can be sprayed with a heteroauxin solution. This composition stimulates the growth of young shoots and promotes wound healing after pruning.
- During the fight against aphids, one should not forget about their companion ants. It will require the destruction of anthills all over the site. Otherwise, the aphids will almost certainly return to the garden.
- Over-saturation of the soil with nitrogen has a negative effect. The introduction of this substance should be carried out according to the instructions and recommendations on the packaging. Excessive and frequent ammonia feeding makes the plant very attractive to aphids and other pests.
- Remember, chemicals cannot be used when apples are ripening on the tree. If there is an urgent need to do so, then you need to abandon the use of fruits, and then destroy the harvest.
- A thorough, high whitewash of the tree protects against fungus and mold on the trunk. It is also a barrier to many flightless insects.
- Very old fruit trees can dry out on their own due to their age. You can support a perennial apple tree by feeding it, timely removing dead branches and cleaning the trunk of dried bark.
- If the foliage is drying predominantly on the top of a young apple tree or seedling, the root system is causing it. Weakened roots cannot deliver nourishment to the upper parts of the plant. In this case, you should carefully examine the zone near the stem for the presence of caves and underground passages of rodents and moles.
Other factors that lead to root damage can include groundwater or the freezing of the soil during severe winter frost.
Often the cockchafer larvae cannot be treated quickly. The fact is that they can live up to a meter deep. Insecticide solutions just don't reach everyone deep in the ground. But it is known that the larvae of this insect really do not like ammonia. If they cultivate the soil in the near-tree zone of the apple tree, the insects quickly leave an inconvenient place. A solution of pharmacy ammonia is made in a proportion of 50 g of the drug per 8-10 liters of water.

The main reason is Verticillus wilt.
In recent years, cases of cherry diseases with vertikillosis, which lead to premature drying out of individual branches and the entire tree, have become more frequent.
In young trees (3-7 years old) the disease begins in spring, the apical flower buds of the bouquet twigs flash one to two weeks before flowering and the inflorescences often wither. If you look closely at the tree trunk, forks and skeletal branches, you will find subtle depressions and rust-brown spots of various sizes. Such spots can occasionally be separated from living tissue by cracks from which the gums flow. The disease is active. If preventive measures are taken, the tree can die off during the growing season.
In trees older than 7 years, the disease occurs in its acquired form: necrosis due to the forms of lesions on the bark of the trunk and on the ray branches. The bark tears around the tree species and peels off in the form of continuous longitudinal strips, creating depressions from which chewing gum flows in abundance. Evenly growing wounds completely embrace the infected part of the plants on whose fungi they settle. Trees slowly dry out over 10-15 years.
Solution to the difficulty
- To prevent the cherries from drying out prematurely, you must meet the following requirements. In the area where it grows, it is impossible to grow nightshade, vegetables, melons, strawberries and sunflowers, in other words, plants that are badly affected by the withering of the verticillum - they can be a source of infection.
- Sweet cherry soil must be breathable. Sweet cherries do not tolerate sluggish loam soils, and Solonchak and Solonetz soils with similar groundwater content, which worsen the aeration of the root system, are undesirable. In my own experience, I plant trees in autumn and at the same time place the root neck at a depth of 4 to 5 cm from the surface.I prune trees in summer (late May to August) when the highest air temperature inhibits the development of microbes. Disinfects the cutting tool with 10% copper sulfate, formalin or carbolic acid. Garden varieties or alkyd paints are certainly covered in the sections.
- In order to protect the trees in autumn and winter from sunburn and frost, which contribute to the development of the verticillus wilt, I whitewash the trunks and the bases of the skeletal branches with a 20% lime substance with the addition of a 2% copper sulfate solution. I brush and rubber the gum ulcer with a putty of clay and mullein (1: 1) and also add a 2% solution of copper sulfate. After heavy rainfall in August-September and the first fall of leaves, I spray 1% Bordeaux liquid or cuproxate. In October - two more treatments with the same products 15 days apart.
- In spring, to disinfect the upper kidneys on which the pathogen hibernates, I spray the trees with 3% Bordeaux liquid or cuproxate. Immediately after flowering, during the period of intense leaf diseases, I spray with Polychom (40 g), Cuproxate (35 ml), Radomil (40 g) or Polycarbacin (40 g). In late July - early August I repeat spraying with the same products. The above complex of protective measures is also effective when apricots and other fruit trees are dried early.
Cherry - the name of the fruit and tree from the Pink family, belongs to the genus Plum. The oldest
It is annoying when, despite all efforts, fruit trees are sick and hardly bear fruit. This is often the case with cherries as well: the tree dries at the tips of the branches and loses its ovary. Let's find out why the cherry is drying and what to do to save the tree.
The causes of the drying out of a fruit tree can be very diverse - from improper care and violation of the irrigation regime to improper pruning and the development of fungal or infectious diseases. Most often, however, the cherry dries precisely because of the disease - a fungal disease. If small characteristic spots appear on the leaves of the plant, you need to take immediate action, since the infection spreads quickly and covers not only the foliage, but also the ovaries, flowers and berries.
Sometimes in the spring gardeners notice that the cherry in the garden has withered. This is explained simply: the tree did not move after the winter because it suffered from severe frost. And the soil moisture regime could be violated - felt cherries are considered capricious plants in this matter.
Another explanation for the cherry drying out is the lack of fertilizer: the tree simply does not have enough food to produce a crop and all that is left is to get rid of unripened fruit.
And the last, most uncomfortable moment is an infection with moniliosis. You can recognize the disease by the characteristic blackening of the ovaries. If you do nothing and do not fight the spread of the disease, it can lead to the fact that you will be robbed not only of the harvest, but of the entire cherry orchard.
How to save a tree
Complex fungicides are used to combat fungal infections. When the first alarming symptoms appear with these drugs, it is worthwhile to intensively treat all affected trees, otherwise dried plants will inevitably die. The same applies to insects - for their destruction there are insecticides with a complex systemic or contact effect that are safe for culture. Mechanical pest control is also useful.
If watering the tree turns black, try adjusting it. Cherry does not like soil with strong groundwater resources. Therefore, carefully choose a location for planting cherry seedlings. The optimal regime of watering for a tree is 1 time in 2 months, using 3 to 5 buckets of water for each plant.
In order not to provoke a lack of nutrients, refill in good time: the tree needs organic fertilizers in autumn, mineral fertilizers in spring and summer (you can find complex preparations for stone fruit cultures in specialist shops).
However, the success of treating moniliosis will depend entirely on how quickly the disease was noticed. To fight it, use the drug "chorus".
In order not to frantically find the answer to the question of what to do to save the garden, when the cherries in it dry out, try to follow the rules of agricultural culture. Do not neglect the mandatory preventive treatments, do not forget to cover the cherries for the winter, protect them from the cold, timely prepare all the necessary fertilizers, water them properly and prune the branches.
