Apple trees are the most common deciduous trees and belong to the variegated family. This genus includes more than 36 species, but no more than 10 of them grow in Russia. Cultivated varieties were bred by crossing low, forest, berry and Chinese apple trees. When the apple tree blooms depends on the climatic conditions of the region where the tree grows. Favorable temperature conditions for flowering range from 15-22°C. The lower the temperature, the longer the color will please the eye.
When does the apple tree begin to bloom?
A blooming apple tree brings aesthetic pleasure: during flowering, numerous white, pale pink, pink and red small flowers are formed, emitting a pleasant delicate aroma.
All apple trees bloom with the onset of spring and early summer, but depending on climatic conditions this occurs at different times. In temperate and southern regions, tree crowns become covered with flowering inflorescences in early spring. In areas with temperate climatic conditions, which give way to cold temperate ones, the flowering of apple varieties shifts to late spring - early summer. Apples readily bloom when the air temperature warms up to 15-22°C. The duration of the color can vary from 6 days to 2 weeks. A healthy tree, as a rule, begins to bloom 3-6 years after planting. In the first year, flowers may fall off.
Note! The abundance and speed of fruiting will also depend on regular sanitary pruning.
With the onset of spring and autumn, trees must be dug up so that the root system absorbs as many nutrients as possible. Once a month the crown is thinned out and the trunk is treated with whitewash. You can't tear off the color.
Blooming apple tree
How many and when do apple trees begin to bloom in different regions of the country:
In the Urals, weather conditions are for the most part not very favorable; it is recommended to use frost-resistant varieties for growing apples in this region. Depending on weather conditions, apple trees can begin to bloom in the second ten days of May and until the first ten days of June.
In the middle zone, the order of apple blossoms is as follows:
- the first ten days of May - apple trees with small fruits on city streets;
- second ten days of May - ordinary homemade apples on personal plots and dachas;
- third ten days of May - wild apple trees and those growing in country gardens.
In Novosibirsk, the duration of flowering of trees is usually 10 days. When is the time to bloom:
- second ten days of May - apple trees growing on the streets of the city;
- third ten days of May - first ten days of June - homemade varieties of apples in the orchard at the dacha.
Apple trees are fairly unpretentious crops that can adapt to almost all climatic conditions. Cold-resistant varieties can withstand temperatures down to −40°C. However, if there is a deficiency of moisture and nutrients in the soil, the inflorescences may crumble or dry out, which will negatively affect the quality and quantity of the harvest - the tree may not bear fruit at all.
Note! In the spring of 2022, apple trees in almost all regions of Russia began to bloom a week earlier. Scientists are still figuring out what this is connected with.
Compared to cherries, the apple tree blooms later, although much depends on the variety. In the southern regions, cherries, as a rule, begin to bloom in the third ten days of April - the first ten days of May. However, the flowering duration is shorter, most often not exceeding 10 days.
Protective measures associated with apple tree blossoms
During flowering, apple orchards are very vulnerable. If the weather is cloudy, cold and rainy, as well as with strong winds, domestic bees almost never fly out of their hives, and many flowers remain unpollinated. In bad weather, only bumblebees and wild bees fly, so it is so important to protect these wild pollinating insects, and for this, first of all, maintain a healthy ecological situation on the site and not abuse pesticides.
Bumblebees are the most valuable wild pollinating insects, regularly visiting flowers even in bad weather.
Frosts are very dangerous during flowering, damaging buds, flowers and young ovaries. The only truly reliable protection against frost can only be considered by covering dwarf trees with protective agrofibre while the air temperature drops.
The recommendations reprinted from book to book on protecting gardens from frost with the help of smoke heaps personally seem very dubious to me. At least here in the Middle Volga, absolutely all classic frosts (short-term sharp drops in air temperature during the night and early morning hours) occur exclusively in clear, windless weather, when any smoke rises vertically upward in a narrow column. Moreover, no smoke can save you from long-term cold snaps with strong gusty winds caused by Arctic cyclones.
Apple orchards suffer greatly from the flower beetle weevil, which is capable of destroying almost all the buds on apple trees during the years of its mass appearance.
The apple tree is blooming, but there are few leaves: reasons
There are few leaves on the apple tree, what should I do? Before you begin to solve the problem, you need to determine the root cause.
When there are few leaves or they are small
Apple tree Pioneer
Photosynthesis and, as a result, the regularity and abundance of fruiting and the quality of the fruit depend on the size and number of leaves. Therefore, the foliage of fruit trees must be closely monitored and maintained at a high level.
Reasons for weak apple foliage:
- Lack or excess of nutrients in the soil . Nitrogen plays a great role in the formation of leaves, and to a lesser extent phosphorus and potassium. A lack of iron can lead to foliage falling, growth will be weak, and the color of the greenery will be pale.
- Freezing of the root system or branches during winter is a common problem in regions with little snow in winters. When the temperature drops to critical levels and the snow cover is insufficiently thick, the roots may freeze, since their frost resistance is lower than that of the branches. Symptoms: Healthy foliage is replaced by small yellow foliage.
- The proximity of groundwater to the surface of the earth . This problem leads to the root system getting wet, which can cause the death of the tree. Confirmation of the close location of groundwater to the surface can be the growth of coltsfoot and nettle.
- Pests and infectious, fungal, viral diseases. The foliage decreases sharply when the tree is affected by the following diseases: powdery mildew; black cancer; scab; milky shine.
- Last year's drought has an effect , but indirectly, through the roots. Rhizome growth is inhibited by a lack of moisture and organic compounds.
Ways to fight
If the cause is the proximity of groundwater, the problem will not be completely eliminated.
If the provoking factor is a nutrient deficiency, then it is necessary to increase the application of fertilizers (root, foliar fertilizing with organic or mineral fertilizers).
Important! When the root system freezes, it is also important to fertilize, and it is better to give preference to organic compounds. Fertilizing can be supplemented with irrigation with stimulating compounds, for example, EM preparations, daffodil, silk, ecogel.
Preventive measures
To maintain foliage in normal condition, you will need:
- plant seedlings in accordance with all rules of agricultural technology;
- prevent the development of fungal diseases;
- regularly add fertilizer to the soil;
- promptly cover up all mechanical damage with garden varnish.
Spraying apple trees in spring
Spraying is a mandatory and integral procedure when caring for fruit trees. After all, every gardener wants his garden plot to look beautiful and healthy, and most importantly, to produce a good harvest. Thanks to the spraying procedure, you can protect your trees from various parasites and harmful bacteria, which can literally, in a short period, nullify all your time and effort spent during the year.
For example, we can protect an apple tree from aphids, which form nodules on the tree bark, which subsequently crack and turn into ulcers. At the same time, if you do not stop the aphids in time, which in addition to apple trees also affects plums, pears, cherry plums and apricots, then the leaves of the trees will begin to curl and then fall off.
An apple tree, like other fruit trees, needs several treatments throughout the year in different ways, but in this article we will mainly touch on the topic of spring treatment of apple trees
The apple tree blooms, but there are no leaves at all: reasons
Apple tree Amber
Many gardeners, especially beginners, are faced with the problem of the absence of leaves on a tree when it blooms. Why are there no leaves on the apple tree?
There may be several reasons why a fruit tree blooms but leaves do not form. The most common are the same nutrient deficiency, excess moisture, frostbite of the root system, cancer or damage by insect pests: apple moth and flower beetle.
- Fruit tree cancer is a serious disease, the consequences of which inevitably lead to the death of the plant. At first, the leaves look as if they were burned with acid. Symptoms of the disease: growths and cracks form on the bark of the trunk, the branches die as they dry out. The main reasons why different varieties of apples suffer from cancer: critical temperatures (scorching unbearable heat or extreme cold), lack of treatment of damage after pruning the branches and forming the crown.
- Groundwater. A common reason why a tree may bloom in the first years, but not form foliage. The optimal groundwater level is 2-3 m. If the water level rises, the root system becomes oversaturated with moisture and stops forming foliage. Characteristic signs - in some places the bark on the trunk begins to separate from the wood.
- A lack of minerals can also cause lack of foliage. In the previous growing season, as a rule, the plant already gives alarm signals. The apple tree awakens with a significant delay. With a phosphorus deficiency, the leaves change their color and a bronze tint begins to predominate. If the root system is deficient in magnesium, the lower branches quickly become bare and the leaves turn purple. This condition is quite dangerous; there is a possibility that the tree will not survive the frost. With a lack of manganese, red and white spots form on the leaves, become deformed and dry out. If the fruits appear, they do not ripen to the end.
- Frostbite of the root system. The risk group includes non-cold-resistant varieties. Symptoms of frostbite: plaque forms on the bark, the trunk and branches are quite fragile. Damaged branches need to be cut back to a healthy place. With the onset of spring, the buds bloom, but the foliage does not appear. In case of severe frostbite, the tree needs regular watering and fertilizing with organic fertilizers. Feeding should be carried out in 3 stages: after the apple tree has finished blooming, 2 weeks after the first feeding, at the end of August.
- The fight against apple blossom beetles and moths involves regular preventive measures. It is necessary to clear the trunks and lower branches of old bark. It is recommended to do this with the onset of the first heat. After this, you should irrigate the plant with special preparations and collect insects by hand.
Apple trees are unpretentious and common fruit trees in our country. For their full growth and development, it is worth following all agrotechnical rules, as well as taking all necessary measures to treat diseases.

This year the flowering sequence of plants has been disrupted
In May we always see the annual spring miracle - the flowering of bird cherry. Just as the Japanese admire the cherry blossoms, we also freeze and, passing by the blooming cherry trees, we will definitely stop or hold back our step. According to long-term observations, bird cherry blossoms in central Russia in the first week of May. In Moscow this usually happens a day or two earlier.
“I didn’t believe in the old sign:
Bird cherry blossoms when it gets colder. "
Surely everyone has heard this song. Here it must be said that the return of cold weather in May happens every year, and the flowering of bird cherry does not always coincide with it.
According to specialists from the State Budgetary Institution “Mospriroda” KGH, this year the flowering of this plant met the deadline. Flowering bird cherry usually “passes the baton of flowering” to the common pear, apple tree, and cherry tree. But this year has become special. In different places, cherry, apple, and pear trees outpaced bird cherry. Nature decided so. The long spring shifted all the dates, and in different places flowers on trees of the same species bloomed at different times. In some places the cherry blossoms have already flown around, and in others they have just blossomed. In some places the bird cherry is already fading, while in others the flowering is in full swing.
Bird cherry begins to bloom when the average daily temperature exceeds +5, but there must be “accumulated” heat for some time. Typically, bird cherry blossoms last 10-15 days. Due to weather instability, these dates may be shifted.
Moscow is also interesting because, in addition to plants typical of central Russia, you can also find exotic species here. The Sakhalin cherry has already faded, its flowering was fleeting, as befits sakura. Maak's bird cherry is just picking up buds. The apple tree is blooming. Wind-pollinated trees such as birch are fading, pedunculate oak is in its active flowering phase, and the buds of mountain ash are budding. And the Hungarian lilac will bloom only at the end of May - June. Typical herbaceous plants in the middle zone are currently blooming: speedwell, ivy budra, common spadefoot spade, and violet.
When do they bloom?
Various types of orchids
When orchids begin to bloom, they need good care. Nuances of preparation
Each species is ready to bloom.
A question that gardeners often ask: when do orchids bloom at home? Here is information for different types of orchids:
After the orchid has finished blooming, a period of rest begins.
kids
mother plant, appear on its stems or roots for various reasons
:
The babies must be separated from the peduncle to give the mother freedom to flower.
- The plant is unhealthy, struggling to continue existing in young shoots;
- Feels great, excess strength gives impetus to;
- The florist created special conditions for the education of children.
Unseparated
Sometimes a child who is not separated develops successfully
and forms its own peduncle! Cases of simultaneous flowering of an adult and an unseparated young plant are often described!
This probably happens when the mother has enough strength
, to “feed” themselves and the new creation. Caring for a “blooming family” is usual, in accordance with the species characteristics.
Separated
The main question is when will the planted baby bloom? The planted baby needs to develop into an adult plant capable of independently accumulating nutrients
Before separation, she is allowed to grow her own roots.
. This will take up to six months. Rooting and growth will follow. This can take up to three years for different varieties.
In order for the purchased plants to live up to expectations, systematic, competent care is needed!
They will provide invaluable assistance with this
- Diary of observations
. Helps analyze actions and correct them; - Pre-drawn calendar plan
. It will not allow you to miss the start date of increasing the illumination, decreasing the temperature of the room, or changing the air humidity.
Understanding and providing for the needs of an orchid is the key to its beautiful flowering
Problems of blossoming apple trees
Apple trees are unpretentious plants, so they are grown in any climatic conditions. But in order to get a bountiful harvest, it is worth providing the tree with sufficient moisture and nutrients.
When there are few leaves on a blooming apple tree
When examining the branches of a blooming apple tree, you sometimes notice that there are few leaves on them. This problem requires a solution. First you need to determine the cause.
Photosynthesis depends on the number of leaves on a tree and its size. Without it it is impossible to get a bountiful harvest. It is worth making sure that the crown is thick, especially when the apple tree is blooming.
The reasons for insufficient leaves are as follows:
- Lack or excess of nutrients in the soil. The presence of nitrogen in the soil, as well as potassium and phosphorus, is important for the formation of leaves. If there is not enough iron, the leaves fall off, grow poorly, and turn pale.
- In winter, the roots or branches froze. This is a common problem in regions where there is little snowfall in winter. If the winter is frosty and there is little snow on the ground, the roots freeze.
- High groundwater. If the groundwater is too high, the roots of the apple tree will gradually become wet. As a result, the tree dies. If plants such as nettles and coltsfoot grow near the apple tree, the apple tree is planted in the wrong place.
- Diseases or pests . If the apple tree is affected by powdery mildew, milky sheen, or scab, few leaves appear.
- Drought inhibits root growth.
How does a plant bloom?
Bird cherry blossoms very beautifully and looks special. During this period, all plants are just beginning to wake up after winter, and buds are already beginning to form, which will soon open and enchant passers-by with their delicious aroma. Soon, a swarm of bees will hover around the falling flowers, collecting the first nectar.
However, despite all this magnificence, you should not abuse them. The aroma of bird cherry, although pleasant, is quite pungent, and if you stay near it for a long time, it can cause headaches and even slight malaise in some people. Therefore, it is better to enjoy this fragrance in the fresh air, rather than cut fragrant bouquets for the home.
Bird cherry flowers are very valuable and have great benefits:
- They can be used as a diuretic;
- They contain a large number of different minerals and vitamins;
- Infusions are made from the flowers, which help in the fight against various skin diseases, and are also used to treat conjunctivitis;
- Compresses made from bird cherry flowers can help with rheumatism, gout and swelling;
- They are used in the treatment of tuberculosis and the initial stage of diabetes, consumed as infusions or decoctions;
- Added to various creams and ointments that have a wound-healing effect.
When the bird cherry blossoms
At the beginning of spring, the buds are just beginning to swell, but from late April and early May
There is rapid growth of herbaceous plants. Just at this time you can see the bird cherry blossom. Sometimes she is called the queen of spring. Perhaps this is one of the earliest spring flowering trees.
The flowering of this representative of the rose family is always associated with the threshold of agricultural work. It is generally accepted that at this time it is time to sow wheat, plant potatoes, etc. And this indicates that there will be a good harvest. That is, the beginning of flowering has long meant for rural residents the time when they could start sowing.
It should be noted that bird cherry usually blooms in the first week of May, however, due to the weather, its flowering can be seen ten days earlier or later. Therefore, it is not easy to say a specific flowering date for this plant. Also, the flowering time depends on the region in which the tree grows. For example, in Siberia, its flowering can shift right up to the very end of May.
Thus , the flowering of bird cherry depends on:
- region of growth;
- spring climate.
Why pick flowers from a mature tree?
There is a technology that recommends partially removing flowers on an adult plant. Experienced gardeners recommend removing approximately 2/3 of the inflorescences. It is especially important to carry out this procedure during the period of active growth - approximately 3 to 5 years. The period of plant formation depends not only on the variety, but also on the climate of the area where it grows. What to do if a two-year-old apple tree blooms should not be a question. It is still early for the fruit to form, so it is better to remove the inflorescences.
Why pick flowers from a mature tree?
On a note. If the tree has reached the stage of 2-4 years and has bloomed only for the first time, and it has become sufficiently strong and well-rooted, then the flowers can not be removed and the harvest can be allowed to form completely.
As the practice of experienced gardeners shows, you can use a special scheme for mature trees, which will help ensure a good harvest:
- During the first year, all buds on the lower branches of the plant should be removed. The harvest will be formed only in the upper part of the crown;
- The next season, the buds should be removed from the top of the tree. The fruits will ripen on the lower part of the crown.
This method of independently forming and adjusting the harvest has many advantages:
- branches that can bear fruit alternately rest and recover;
- the harvest is greater;
- the apples are much juicier and larger.
Why doesn't the tree bloom?
Winter varieties of apple trees themselves can begin to bear fruit only in the 7-8th year of planting a two-year-old seedling. Of course, this is completely unusual for summer varieties.
The most popular “mistakes” of novice gardeners:
1. Large penetration into the soil. The root collar of the apple tree should not be buried into the soil at all; they try to leave it just above the surface of the soil. Otherwise, the tree may refuse to bloom and bear fruit for a very long time. If upon closer examination it becomes clear that the trunk is too deep when planting, you will have to start raising the tree or digging a hole around it.
2. Vertical arrangement of all branches. An apple tree usually bears fruit on horizontal branches, which is why it is so important to help ensure the correct formation of the crown. One way is to hang a small weight on the edge of a branch, gradually increasing its weight. It is important not to rush, otherwise the branch may break.
3. Lack of iron. Apples are famous for their rich iron content, so its lack in the soil already affects the stage of flower formation. Previously, in villages, two rusty nails were driven into a tree trunk or several rusty metal objects were buried under an apple tree, increasing the iron level in this simple way. Modern gardeners prefer to spray trees with a solution of iron sulfate (0.1%).
4. Diseases and insects. A careful examination of the branches and leaves will reveal the harmful source due to which the flowers do not bloom. Each case has its own method of controlling various pests.

How to care?
Fruit trees can grow with virtually no unnecessary human intervention if they are given enough attention at the very beginning of their development. How to care for an apple tree:
1) Landing. Apple tree seedlings are planted in a permanent place in mid-spring, although many people purchase them from nurseries in the fall, when they can boast a large selection of varieties. In winter, the seedlings are stored in a trench, and as soon as the snow melts and the top layer of soil has completely thawed, they are planted in planting holes.
The roots are carefully spread out on a mound inside the hole, and soil is poured on top. The boundary between the roots and the crown (root collar) must be strictly at ground level, otherwise the tree will develop slowly. The soil is compacted with a foot, and then the hole is watered at the rate of 2-3 buckets per 1 tree.
2) Watering. Apple trees 2-3 years old need frequent watering, but with a small dose. The irrigation rate is determined taking into account soil moisture to the depth of the root system. Typically, young trees with a hole about a meter in diameter calmly absorb 3-4 buckets of water. The next watering is carried out after 15-20 days. Fruit-bearing apple trees with a crown with a diameter of 3 m need more watering - about 35-42 buckets of water.
One good watering per month is enough for them. The older the tree, the more effective heavy infrequent watering is compared to frequent small doses. You can't always see how an apple tree dries up. But it is better to focus not on the appearance of the tree, but on the long absence of rain when deciding to water the hole under the apple tree.
3) Soil cultivation. Weeds can damage not only young but also mature fruit trees. Weeds draw a lot of nutrients and moisture from the soil, inhibiting the growth of cultivated plants. Systematic control of them is very important for successful flowering and fruiting of the apple tree.
It is advisable to remove weeds with their roots so that they are less annoying when they appear. The use of herbicides in orchards is extremely undesirable, so it is better to ignore all advice on their use. It is also very important to deeply loosen the soil before each watering.
4) Fertilizer. If the soil is poor in humus, then humus, superphosphates and potassium fertilizers are placed in the planting hole. Then, every 2-3 years before the buds open in the spring or autumn, at the end of the growth processes, mineral fertilizers are applied along with humus. They are not only embedded in the soil to a depth of 10-12 cm in the area of tree trunk circles, but also scattered in the aisles where there are no roots.
5) Regular inspection. Young trees like to be attacked by weevils and caterpillars that eat green leaves. A timely response to their appearance will save the apple tree from death.
Diseases and pests
Apple tree diseases and pests:
The green apple aphid is an incompletely metamorphosed insect that can significantly damage and deform the shape of leaves. The locations of damage are well identified by soot deposits.
Powdery mildew is a dirty white powdery coating that covers the buds, leaves, inflorescences and shoots. Over time, the plaque turns brown, forming small black dots.
Scab is spots with a greenish-brown coating on leaves or fruits. The disease develops early in the spring, immediately after the buds swell. Leads to drying and further falling off of leaves. When apple trees bloom, the scab moves to the formed flowers and waits for the fruit to appear. Affected fruits may grow one-sided and cracks appear.
Fruit rot is large grayish-brown pads consisting of rot spores. They are located in concentric circles on the surface of the fruit. Capable of easy separation with gusts of wind, using it to infect other fruit-bearing trees.
Rust is a fungal disease that attacks leaves. It looks like swelling-pads of a red-brown or orange hue, reminiscent of rust on metal.
Sooty fungus is a black coating that envelops the surface of leaves, shoots, ringlets and fruits.
The apple stalk is a small butterfly with a wingspan of 14-20 mm. Capable of eating most of the fruit.
Basic methods of healing
Treatment of apple trees:
Spraying with infusions and pesticides. For each disease there is a list of drugs that can be used with minimal harm to the apple tree itself. For example, aphids are removed with a solution of laundry soap (rub 50 g onto a bucket of water). You can dip the ends of the shoot into the liquid or generously spray it.
Inspection and cleaning of wood. Various caterpillars, oviposition, sources of infection can be seen already in the initial stage of development. If you regularly inspect the tree for “unwanted guests,” then the measures taken will be more effective than after they actively reproduce.
Preventive measures. Autumn digging of row spacing and tree trunk circles allows you to destroy the wintering stages of scab, eliminating its appearance in the spring. Burning fallen leaves will kill the main larvae. Creating trapping belts will allow you to catch the bulk of the pests. The crown of trees should be whitened to prevent caterpillars and bugs from crawling from the ground.
Natural control measures. Birds and ladybugs can significantly reduce the numbers of caterpillars, mites, psyllids, codling moths and codling moths.
Preparations for spraying
What to spray apple trees with? To combat the main pests, spray Bordeaux mixture (3%) on dormant buds. In parallel with this, you can make various infusions or decoctions from wormwood, chamomile, yarrow, tomato tops and potatoes. Plant control measures are not as effective as chemical treatment, but they are safer for humans and ripening fruits.
In modern gardening, biological products are becoming increasingly common, after using which you can harvest within 1-5 days. Compared to chemicals, which have a 30-40 day limit, they are a worthy alternative to “grandmother’s decoctions.”
No matter how scary the numerous advice given to gardeners may be, growing apple trees is actually not such a difficult task. It is better to solve problems as they arise, then the long path to the harvest will seem easy and exciting.

If a two-year-old apple tree blooms
Theoretically, a two-year-old apple tree should not yet bloom, since the plant has not matured and is simply not ready to produce a full harvest. But there are times when a two-year-old crop begins to bloom, and very actively. Gardeners are simply at a loss what to do. They understand that they need to remove the inflorescences, but they already want to get a good harvest.
- If the tree is strong and well-rooted at the age of 2 years, then you can leave the flowers and try your first harvest. But it is important to provide adequate nutrition and care so that the plant has enough strength.
- If the apple tree is not yet strong enough, it is better to pick off the flowers and give it more time to strengthen. For the sake of experimentation, you can leave 1-2 inflorescences just to try this variety.
Why do apple trees bloom for the second time this summer? How normal is this?
Caroline
Flowering of some plants a second time (usually in autumn) is becoming more common. This behavior is explained by the fact that abnormally warm weather in the fall “deceives” the plants, provoking repeated flowering. Often this is a consequence of cold winters and hot summers, and not an environmental disaster. The out-of-hours flowering of apple trees can be explained by a kind of “hormonal imbalance” in the tree’s body, caused by drought, high humidity or other vagaries of nature.
This atypical phenomenon can occur even in areas of risky farming. For example, in Tyumen, several years ago, the only apple tree on our site bloomed again after successful fruiting. It was unusual to see the juxtaposition of ripened fruits with blossoming apple tree flowers.
And in Yekaterinburg in 2003, apple trees generally blossomed at the end of October, when, according to our standards, it was time to prepare for the first snow.
Tju
It happens that one branch of a tree blooms in autumn. And then this branch dries up. Such flowering is like a swan song, the last flowering before death (Old people say so, but they are rarely mistaken. But why sap flow intensifies in a single branch, and it loses its “orientation” to the time of year, it is difficult to explain. Maybe this is something... something like a “hormonal surge” from some kind of tree disease?
Marina82
This situation happens if the summer was very hot. Trees are known to bloom after a dormant period (winter). During a very hot summer, the tree may also “calm down” for a while, enter a period of dormancy, that is, life processes slow down. Then it begins to bloom, but not as profusely as in spring.
Lorelei
Repeated flowering of apple trees most often does not occur in large numbers; there are usually not many flowers. The main reason is hot weather and weather fluctuations. Because of this, the balance of substances in the apple tree that regulate its development is disrupted. The buds that are laid for the next year cannot stop developing in time.
If the re-blooming was relatively abundant, then there will be no harvest next year.
Spraying apple trees in spring
For the first time in the spring, the apple tree must be sprayed even before the buds open. The purpose of this event is to prevent fungal diseases, as well as to exterminate harmful insects that managed to successfully overwinter in the garden plot.
But in general, during the spring period, this procedure must be carried out three times: before buds open, during and after flowering.
How to treat an apple tree in spring?
The treatment agent must be selected depending on the type of pest.
The most popular of them are:
- Urea . The greatest effect can be obtained by treating wood with this product immediately after waking up. Urea is capable of excellently burning insects even if they are still in the cocoon. But in addition to the fact that urea is capable of destroying harmful larvae, eggs and caterpillars, it also activates vegetative processes. Since urea is also an excellent means of saturating plants with nitrogen, it can be used several times throughout the year to feed garden trees.
- Copper sulfate or Bordeaux mixture . The apple tree is sprayed with one of these products approximately two weeks after flowering. Effective against mites, moths and other pests. It is a prophylactic against scab, moniliosis, anthracnose, etc.
- Inkstone . It works almost the same way as the previous one. However, for the apple tree this remedy is used not only for preventive purposes against insects and diseases, but also as a nourishing agent, such a very important microelement for it as iron. With a deficiency of this substance, the growth of the apple tree, as well as the quantity and quality of the future harvest, deteriorates.
In addition to the above substances, you can spray the apple tree with various liquids. At the moment, specialized stores have a large assortment of combined mixtures to combat a variety of pests and diseases, including substances that are beneficial for the apple tree.
Spraying technology
For treatment you will need: a special liquid (fungicide dissolved in water), a pump (processing apparatus) and protective equipment (gloves, mask, goggles).
The easiest way to process columnar apple trees. That is, all you need to do is walk around the plant and spray the fungicide over all surfaces. There is no need to climb a ladder or twist yourself to get to an inconveniently growing branch.
In the case of a young apple tree, this procedure will be a little more difficult. Namely, you will need to spray the solution over the entire surface of the tree, starting from the trunk and ending with the top. At the same time, you need to try not to miss more than one branch.
Young growth must be sprayed extremely carefully, since the concentrated solution can cause chemical burns in the thin bark and fragile shoots. Therefore, before starting this procedure, it is recommended to carry out a small experiment, which can be done as follows:
- Choose any of the plants;
- Apply the mixture to one of the branches;
- We wait 2-3 days;
If during this period you do not find signs of burns on the plant, the liquid can be sprayed throughout the garden. By the way, it is best to choose a young plant as an experiment, since in the case of an old apple tree, the end result can be one of two things: a damaged branch, which due to its age will not be able to recover; the chemical composition will not be able to greatly harm the thick bark of the tree, but after a few days (with complete treatment of the garden), such a composition will eat young plants.
Treatment during the growing season
Before flowering, the apple tree is sprayed in order to combat fungal diseases, as well as to exterminate beetles that survived after wintering. However, many insects wait out the cold in the soil and appear on the site during the flowering period.
During flowering, the apple tree is sprayed to combat copperhead, mites, aphids and leaf rollers. For these purposes, you can use Bordeaux mixture, copper or iron sulfate, as well as substitutes for these fungicides - colloidal sulfur, etc.
against the codling moth a little later, after the buds set or the petals fall.
After flowering, it is recommended to spray the apple tree no earlier than two weeks after the petals fall. If signs of scab or clay diseases are detected on the tree, a little copper oxychloride must also be added to the liquid.
