Why the apple tree does not bear fruit and how to fix it?
Apples are the most demanded and popular fruit in many countries of the world. These fruits not only have high taste qualities, but also contain a large amount of vitamins and minerals that have a beneficial effect on human health. Apple trees can be found in all household plots, in specialized nurseries, in the gardens of farmers and agricultural companies.
Professional breeders have bred a large number of varieties of this fruit, which differ in appearance and taste, ripening time and shelf life. Not all gardeners can grow and harvest a decent harvest of these fruits. Beginning summer residents may encounter a number of problems that prevent fruiting. Before laying an apple orchard, you should carefully study the advice and recommendations of experienced gardeners and breeders.
Possible reasons
When receiving low yields from a planted apple tree this year or a complete lack of fruiting, when there are no fruits at all, professional gardeners recommend first establishing the causes of low yields, and then starting to take a number of necessary measures to eliminate them.
The main reasons for the absence of fruits can be several:
- Violation of agrotechnical rules and regulations. Before planting apple trees, you need to know the conditions that may affect the yield of the future tree.Among the main conditions, the following should be highlighted:
- soil infertility and its poor quality;
- surface occurrence of groundwater sources;
- deepening of the root neck;
- planting a young plant at the wrong angle;
- choosing the wrong place for a tree.
Having made these mistakes, gardeners postpone the time for obtaining fruits for several years.
- Tree age. The fruiting of trees depends on the variety and can occur after 5, 6 or even 8 years. Before harvesting, it is necessary to give the plant time to form a powerful root system and crown. Only a strong and healthy plant can produce a large number of fruits. The lack of fruit on the acquired tree can be caused by a number of reasons:
- acquisition of a very young plant;
- sorting;
- purchase of ungrafted or wild seedlings.
Old apple trees also will not give large yields. Temporarily extending the fruiting period is possible only through regular pruning. To collect stable crops, it is necessary to constantly plant young trees and uproot old ones.
- A high percentage of mineral and organic fertilizers in the soil. The introduction of nitrogenous fertilizers in large quantities contributes to the growth of the tree, but becomes an obstacle to the formation of fruits.
- Kidney damage. Buds of apple trees can be damaged due to the onset of severe frosts in winter or a sharp drop in temperature in spring. Diseases and pests can also damage flower buds. Trees with affected buds not only do not bear fruit and do not produce a quality crop, but also stop growing and fully develop.
There are several reasons for cyclical harvesting.
- Getting a lot of fruit in the previous year. For the re-formation of apples, a tree needs to have an adequate supply of strength and nutrients. After collecting a large number of apples, the plant will not have the strength to form a quality crop for the next year for a long time. This feature is typical for trees that are more than 10 years old. The interval between fruiting can reach more than 6 years.
- Individual properties of the selected variety, its genetic individual characteristics. When purchasing young trees, it is necessary to carefully study their varietal characteristics. Some species are characterized by irregular fruiting and periodic fruit formation.
- Frostbite of flower buds. This problem is typical for some types of apple trees with small fruits.
- Incorrect formation of the crown and its thickening. This type of problem prevents dwarf trees from fruiting.
- Wrong care. Columnar apple trees require increased attention and special care for the formation of a large and high-quality crop.
- Mechanical damage during the formation of the crown and the removal of a large number of branches. Starting the pruning process, you need to carefully study the structure of the apple tree. Removing a large number of shoots will stop the fruiting process. The tree will begin in the second year to give all its strength to the set of green mass.
Poor pollination
In the spring, on the branches of fruit trees, you can see a large number of flowers, and in the fall, the volume of the harvest does not live up to expectations. The reason for this situation is poor pollination. The quality of pollination depends on climatic conditions and proper planting of apple trees. Plants planted next to trees by pollinators will always have a large number of ovaries and quality fruits.
The lack of full pollination is one of the main reasons for the lack of a large crop. A small number of apple varieties belong to the group of self-pollinated plants. To create favorable conditions for pollination, there must be at least 3 trees with the same flowering period on the site.
It is necessary to pay attention to the fact that in some varieties the fruits ripen at the same time, and the timing of flowering is different. Professional gardeners do not recommend spraying gardens during the flowering period. This procedure can significantly reduce the yield of apple trees.
Diseases
Most varieties of apple trees have low resistance to various types of diseases. Affected orchards are not only unable to produce a large number of fruits, but can also die from the destructive effects of infections. Diseases of apple trees are provoked not only by viruses and bacteria, but also by bad weather conditions and agricultural errors.
The most common types of diseases are:
- fungal - ashcape, scab, fruit rot, rust, phyllosticosis, black cancer, milky sheen;
- bacterial - bacterial cancer, necrosis, burns;
- viral - mosaic, small-leaved, proliferation, stellate cracking.
Adverse weather conditions and mistakes during planting and care provoke the appearance and development of non-infectious types of diseases that can cause the appearance of fungal, viral and bacterial diseases.
Infectious diseases - a type of disease caused by the appearance of pathogenic microorganisms and penetrating into the structure of plants through damaged bark and other mechanical damage.
Fungal diseases are a mycotic type of diseases provoked by the action of spores of pathogenic organisms.
Bacterial diseases are a type of disease provoked by unicellular organisms (bacteria).
On the shelves of specialized stores you can buy a large number of products that will not only help cure the disease, but also prevent its occurrence.
Wrong care
An apple tree, like any other plant, requires attention, care and proper care. The greatest number of agrotechnical works must be completed in early spring, before the onset of hot weather conditions. Spring agrotechnical work consists of several stages:
- removal of unnecessary young shoots and dry branches;
- treatment of damaged sections of the trunk;
- carrying out a number of measures to prevent the emergence and reproduction of dangerous insects;
- increasing the level of nutritional value of the soil by applying mineral and organic fertilizers.
In autumn, it is enough to remove fallen leaves and protect young plants from frost.
Failure to take all measures to care for the plant or their complete absence will lead not only to the absence of fruits, but also to the drying of the entire tree.
Late removal of covering material can lead to rotting of the trunk and the appearance of mold and dangerous pests in the collapsing bark.
Refusal to treat diseased and damaged areas will provoke the death of the plant, and the absence of lime whitewash can lead to burns on the plant and peeling of the bark.
If you do not remove old foliage and rotten fruits near the plant in early spring, you can provoke the appearance and reproduction of a large number of dangerous insects.
Fertilization should be carried out taking into account the type of soil and the age of the tree.Lack or excess of mineral or organic fertilizers will adversely affect the growth and fruiting of the fruit tree.
It is forbidden to dig the soil near the trunk. This procedure will disrupt the root system and cause it to dry out.
How to solve a problem?
There are many ways to bring a tree back to fruition. Let's take a closer look at the main types.
Transfer
In case of improper planting of young plants, the situation can be corrected by two methods:
- creation of comfortable conditions;
- transfer.
In cases where it is difficult or impossible to transplant trees, experts recommend several ways out of a difficult situation:
- creation of a new drainage system to reduce soil moisture;
- additional application of mineral and organic fertilizers that improve the quality and structure of the soil;
- installation of special support pillars to correct the slope of the growth of fruit trees.
Reducing the depth of the planting hole is not a viable solution. This manipulation will lead to the harvesting of the first crop later than the planned time, but will create conditions for the growth and formation of a strong tree. The deepening of planting material has undeniable advantages:
- formation of additional roots to create a powerful and healthy root system;
- protection of the grafting site from the effects of low temperatures in winters with little snow.
If all the measures taken at the site of the initial planting of the apple tree are ineffective, it is necessary to change its location
The chosen place should not be on the north and windy side.
The method of transplanting trees is also used if a non-fruiting plant needs to be moved to pollinating trees or to more comfortable conditions for growth.
Transplanting is a complex and painful process for a tree. I recommend transplanting only young plants that can take root in a new place. Starting this procedure, you must carefully study all the rules and tips so as not to damage the young plant.
The most favorable time for moving an apple tree is early spring or late autumn. With a garden shovel and pitchfork, carefully dig out the root system of the plant, trying not to damage healthy roots, and remove dry and damaged root shoots with pruners.
Put the dug up plants in a prepared special bag for transportation to a new place.
A tree is installed in the prepared planting hole, covered and tamped with nutrient soil. The root neck should be at least 10 cm above the surface. The plant is watered abundantly, I mulch the place around the trunk. In order for the plant to take root in a new place, it must be regularly watered and protected from pests.
Processing with special tools
Dangerous insects and diseases can cause not only a decrease in the number of fruits, but also cause the entire tree to wither and die. In order to avoid an unpleasant situation, it is necessary to treat the orchard with special preparations several times a season.
Processing from pests is carried out at certain stages of the development of the apple tree:
- at the beginning of the spring period before the awakening of the kidneys;
- before flowering;
- after flowering.
The composition of the most popular and sought-after chemicals includes copper and sulfur. In specialized stores you can find a large number of drugs of this group. Experienced consultants will help you make the right choice and purchase the right product.
top dressing
Top dressing is an important stage of agrotechnical measures. Fertilization should not be chaotic. It is necessary to apply mineral and organic fertilizers in the proportions indicated by the manufacturer on the package. A large amount of nitrogen in the soil will lead to a decrease in the volume of fruits or to their complete absence. It should be noted that nitrogen is contained not only in mineral fertilizers, but also in manure.
Preventive measures
To obtain large fruit yields, it is necessary not only to eliminate the causes of the absence of fruits, but also to use preventive measures. There are several ways to increase the yield of fruit trees.
- Correct formation of the crown of trees. This process must begin from the first year of growth of a young plant. A fruit tree needs a lot of sunlight and enough space to form quality fruits. Experienced gardeners recommend not just chaotic pruning, but carefully study all the subtleties of this procedure. The optimum height of the trees should be no more than 4.5 meters.
Fruit trees over 6 years old should be topped off annually. If it is necessary to remove a large number of old branches, this process must be carried out for several years. Vertical branches are recommended to be removed or fixed in a horizontal position.
- Removing excess flower buds. The rationing method makes it possible to harvest annually from all the trees in the garden. Experienced gardeners recommend leaving no more than 15 buds on each shoot. It may not be possible to collect a large number of fruits, but you can get a high-quality and moderate harvest every year.
- Planting plants according to the lunar calendar. An unconventional method of preventing the absence of apples. If you plant an apple tree three days before the appearance of a new moon, you can get a harvest in a shorter time.
- Scaring trees with an axe. An unscientific way to increase productivity. Experienced gardeners note its effectiveness and efficiency.
To obtain a stable harvest of apples, it is necessary to carefully study the rules for planting and growing fruit trees. Professional gardeners and breeders will help beginner summer residents with advice and recommendations. To create beautiful orchards that will delight owners with large yields, you need a little knowledge, patience and desire.
