Why red currant does not bear fruit, what to do. Why blackcurrant does not bear fruit - several reasons. The value of blackcurrant

Almost all household plots grow various vegetables and fruits. A special place among fruit and berry plants is given to currants. It has unique healing properties, which our great-great-grandmothers knew about. However, not all owners know how to properly care for this shrub, so many of them sooner or later begin to wonder why blackcurrant does not bear fruit. You will learn about the causes of such a problem from today's article.

Why is this plant valued?

The cultivation of wild shrubs began to engage in the monks who lived on the territory of Kievan Rus. This happened in the distant X century, and from that moment it began to be bred in almost all European states. Those who know why it does not bear fruit well will also be interested in how this plant is useful.

Berries, buds and leaves of this shrub have excellent healing properties. They contain a large amount of essential oils, so they are used as a disinfectant. In addition, blackcurrant has a diaphoretic, diuretic and fixative effect. It contains many different vitamins, including A, P, B and C. It is also rich in iron, phosphorus, magnesium, calcium, potassium, sodium, pectins, flavonoids, glycosides, glucose, organic acids and tannins.

Why does the blackcurrant bush not bear fruit?

Under favorable conditions, this plant produces an annual crop. Moreover, the peak of fruiting falls on the fifth year from the date of planting. With proper care and favorable conditions, about thirty kilograms of berries can be harvested from one hectare. However, some gardeners complain about the lack of a good harvest and begin to look for reasons why blackcurrants have ceased to bear fruit.

One of the most important factors that can reduce the number of ripe berries is early flowering. If it fell on a cold period, when pollinating insects do not show proper activity, then you should not count on getting a bountiful harvest.

The second, no less important, reason is an improperly formed bush. Some amateur gardeners, out of inexperience, leave an excess amount of basal shoots or completely ignore this process.

Choice of landing site

Those who want to figure out why blackcurrant does not bear fruit should understand that the yield also depends on where the bush is located. Perhaps it was placed in the shade and it does not have enough sunlight. Or maybe, on the contrary, currants grow along the fence, which warms up in extreme heat and kills fruits that have not had time to ripen.

How to form a bush?

So that you don’t have a question in the future: “Why doesn’t blackcurrant bear fruit?”, You need to provide it with proper care. In young bushes planted in early spring, it is necessary to cut off almost the entire ground part so that no more than two or three buds remain on each branch. This manipulation provokes the formation of new basal branches.

A year later, in early spring, you need to cut the shoots so that two buds remain above the soil surface. For further fruiting, usually no more than three shoots are left. All other branches are completely deleted.

In the third year, twelve healthy basal shoots are left on the shrub, in the fourth - no more than twenty. These manipulations contribute to good fruiting. Quite large berries appear on the bush formed in this way.

Diseases that reduce productivity

For those who do not know why blackcurrant blooms but does not bear fruit, information about ailments that prevent the normal formation of berries will be useful.

One of the reasons for the lack of a crop may be reversion. A currant leaf affected by this disease becomes longer and acquires a pointed shape. The characteristic aroma ceases to emanate from the plant, and the flowers change color to purple. Bushes infected with reversion must be dug up and destroyed.

Another pest that prevents fruiting is the bud mite. To prevent its occurrence between the bushes, it is recommended to plant garlic. A tick that infects young kidneys actively develops inside them.

For those who want to understand why blackcurrants do not bear fruit, it will be interesting to learn about another reason. It is a glass butterfly. Leaves affected by this pest begin to wilt. The insect gnaws passages inside young shoots. Affected branches must be cut and sealed with garden pitch.

Is it possible to rejuvenate old currant bushes?

This is done by cutting off the entire ground part, with the exception of annual healthy branches. Moreover, the root shoots are shortened so that only one or two buds remain on the surface of the soil. During the first two years after rejuvenation, it is recommended to carry out the procedure for the formation of a bush, making sure that as a result no more than five or six shoots of different ages remain.

To grow a strong and well-bearing currant, you need to regularly fertilize the soil with humus and mineral supplements, as well as loosen and water it in a timely manner.

Blackcurrant shrub - unpretentious in cultivation. It successfully bears fruit, both in the northern regions and in European countries. At the same time, blackcurrant blooms in garden plots, but does not bear fruit. What is the reason for this, and how to make blackcurrant bear fruit, you will learn from today's article.

Currant bears fruit annually, regardless of the place of cultivation or region. The berry is one of the perennial plants. The peak of flowering and fruiting falls on the 5th year from the date of planting.

In the first year of its life, the currant traditionally does not bear fruit, but blooms. This is quite normal - the bush is just beginning to form, the root system is not yet strong enough, and the currant itself has not gone through all the natural stages of development.

Blackcurrant begins to bear fruit after flowering in the second year. After this period, fruiting should be regular.

Why blackcurrant blooms, but does not bear fruit:

• shading
• Wrong landing site
• Extreme heat/direct sunlight
• acidified soil
• Lack of moisture in the soil

What needs to be done to restore blackcurrant, after identifying the problem.

• Preparing blackcurrant for planting, you need to work on the site. The soil mixture should not be strongly acidic - liming will help to cope with the increase in acidity.
• The place for planting blackcurrant is chosen moderately lit, without constant shading or exposure to direct sunlight in the midst of summer. The land on the site should be loose, nutritious, let in moisture and air, but not dry out quickly.
• It is also necessary to moisten the ground for blackcurrant regularly, adhering to the rule of drying the soil by 4-5 cm.

Bushes without ovaries - why does not blackcurrant bear fruit?

Blackcurrant may not bear fruit due to the lack of ovaries. Due to an unsuitable climate or an incorrectly selected variety for the planting region, currant bushes may not form ovaries.

In addition to the above reasons, there are no ovaries if there is not enough pollination, which depends on the ratio of male and female inflorescences (blackcurrant is a self-pollinating plant). The gardener can independently, armed with an ordinary artistic brush, transfer pollen between the bushes. You can also pre-plant honey flowers next to blackcurrants.

Why blackcurrant blooms but does not bear fruit: diseases

Diseases and pests on blackcurrant:

• Mite. Develops in the kidneys. When blackcurrant buds infected with mites are found, they are removed. Garlic is planted next to the berry.
• Glassware (butterfly). In addition to the lack of fruiting, flowering blackcurrant is characterized by partial wilting of shoots. It is necessary to cut them almost to the base of the trunk and treat the places of removal with garden pitch.
• Ants. Insects eat away the inside of the flower, leaving the sepals. Ants are killed on blackcurrants with the help of biological or folk remedies.
• Reversion (disease of lack of fruiting). It manifests itself in the form of an elongation of a blackcurrant leaf. It acquires a characteristic pointed end and ceases to exude its specific smell. Inflorescences turn purple, berries do not set. Blackcurrants are completely uprooted and burned - it is not curable.

Tell me what's wrong with my currant. Her branches have become almost bare, and only at the top are small leaves and a few inflorescences. I planted my currant about seven years ago with a seedling bought in a nursery. The yields were good, the berries are large. But now the branches are bare, it seems that they are drying.

Nearby, near a neighbor, large old currant bushes grow. They have grown strongly in breadth, and are almost in contact with my currant. But the yield on old bushes is very low. It is obvious that they are sick. Can my currant "get infected" from the neighbor's? How to keep the variety?

E.N. Stolyarov, Penza

Currant is a very profitable and useful culture. But often in amateur gardens, it does not give the yields that the variety is capable of. Due to errors in agricultural technology, the bushes do not bear fruit for years, but they are not uprooted. It is a pity to destroy a large bush, and every year people hope that the harvest will finally come. Sometimes they simply don’t know what the bush is sick with and how to deal with it. Do you have such a situation? Let's try to figure it out.

We make a diagnosis

According to the description of the appearance of currants, it is difficult to draw an unambiguous conclusion. This phenomenon can be caused by several reasons.

First of all, currant bud mite. In the initial stage of infection, single buds can be collected in autumn or early spring. But if this is not done and other measures are not taken, then the mites will multiply rapidly and can damage 40 - 80% of the kidneys. Damaged kidneys are easy to distinguish from healthy ones. They are round, much larger than usual, and most importantly, do not bloom. If there are many such buds, then the branches look bare, because the leaves have not blossomed.

Secondly, currant glass jar. This is a butterfly that lays its eggs in young shoots. The larvae live inside the branch, eat away its core and move down it. Infected branches show no external damage. But the presence of a pest can be determined by cutting off the shoot. If there is a black hole in the center of the cut, then a glass case is operating here. Damaged branches do not develop, look bare, and then dry up.

From the larvae, a young generation of butterflies develops, which damage new branches of the same bush. The berries become smaller, the yield is greatly reduced.

Thirdly, currant ages quickly. Branches older than 5 years lose productivity. Lateral shoots are not formed on them, and the crop is formed only on the upper short growths. Because of this, the old branches look bare and sick.

How did the infection happen? Glassfly butterflies could fly from any currant plants. But the bud mite could well have moved precisely from the sick bushes of the neighbors. With a close location of plants, small ticks could be carried by the wind. During the harvest between your own and neighboring bushes, you could bring ticks yourself, through clothes.

Often, all currants in the garden are infected with a kidney mite, since the bushes are planted very close.

Our mistakes

1. A preventive examination of currants should be carried out every spring, and not wait until the bush looks “naked”. Then it is possible to identify both the glass case at an early stage of infection, and the kidney mite. As long as the insects have not multiplied to the level of an epidemic, it is much easier to deal with them.

2. It is necessary to collect tick buds annually, and long before the leaves bloom! When they blossomed, the mites had already left the buds and settled along the branch. This is the basis of a very common misconception. Many gardeners believe that if the collection deadlines are missed, then there is no point in destroying diseased buds. And they do not do this, postponing the procedure until next spring.

This is a big mistake. The fecundity of ticks is very high. Sucking out the juices, during the season they greatly deplete the bush. It is necessary to spray the plant and be sure to remove all round buds. Even after the leaves bloom and before flowering, the female mites still lay their eggs in the same buds. Before they leave, they manage to give another 2-3 generations. And in the summer they hide in "inflated" kidneys during bad weather. It is necessary to deprive them of this refuge.

3. Against ticks, the same means (insecticides) are used as against most insect pests. Often sprayed with Inta-vir. This is mistake. You should know that spider mites are not insects, but belong to arachnids, so pesticides (so-called insecticides) in most cases do not work on them.

Against ticks, there are special preparations called acaricides. INTA-VIR is not included in the number of acaricides.

Control measures

So, inspect your plants (and at the same time the bushes of your neighbors). You will see a lot of round buds, which means that the tick is to blame. But don't stop there. Often, currants are affected not only by a tick, but also by a glass case. Cut off part of the suspicious branch. If you find a black hole, you will have to fight with a glass case.

In the event that there is no such damage, perhaps the bush is simply outdated. By the way, the aging of the bush is accelerated by improper agricultural practices, in particular, the lack of regular pruning.

Depending on the diagnosis, you need to choose a method of currant treatment and immediately begin to act.

Against tick. Collect and destroy all tick buds, regardless of the season. Severely affected branches cut and burn. Currant bushes, on which there are many such branches, uproot and burn. Do not plant new currants in this place.

For the prevention of kidney mites, use only healthy planting material. Before planting, seedlings are completely immersed in an acaricide solution. Can be used fitoverm, Aktelik, Fufanon, Regent. In all cases, prepare the solution according to the instructions, but to increase the efficiency of the phytofarm, double its dose compared to the norm. Keep the seedlings in the solution for a day.

They also practice reproduction by green cuttings in artificial fog, where the tick dies.

During the growing season, it is necessary to spray plants infected with a tick with an acaricide solution.

To scare away ticks, onions and garlic are planted among currant bushes. During the period of inflorescence advancement from folk remedies, spraying with a freshly prepared solution of garlic (60-70 g of crushed cloves per 5 liters of water) also helps. With a higher degree of damage (10-15% of the kidneys), a solution is used colloidal sulfur(60 - 80 g per 10 liters of water). At the same time, do not allow the solution to get on the gooseberry bushes in order to avoid falling leaves.

Against glass. Selectively make cuts on suspicious branches. When a black hole is found in the center, the branch is cut below, capturing part of the healthy wood. Cut branches are burned.

During flowering, the shoots on which the leaves wither are carefully examined and cut to healthy wood, where the back door ends. All sections are covered with garden pitch.

If the infection is too strong, the bushes are completely cut off in the dormant bud phase in order to renew the shoots. Cropped bushes tend to increase yields. Relatively resistant varieties are used - Smart, Karelian, Nevskaya, Full, etc.

A low yield of currants is not necessarily associated with the presence of pests or diseases. Some varieties of currant shed their ovaries with a lack of moisture after flowering. This is especially true in sandy soils. Shrubs are usually watered with a hose. But at the same time, only the top layer of soil is wetted, and moisture does not penetrate into the root zone. Watering rate depending on the age of the plant: from 1 to 4 buckets per bush.

Try an experiment. Record the time it takes you to fill a bucket of water with a hose. The next time you water currants, consider this time and water enough to pour out water at least as much as normal.

M.B. Sharova, biologist

It is believed that currant is an unpretentious plant. And this is actually so - it grows for itself in the forest without any care, and besides, it also bears fruit. But it also happens the other way around, when the bush looks good, develops normally, but there are no berries. Why is this happening?

If the bush is no longer young, has been in the same place for many years, but does not even try to bloom, then most likely the matter is its age. Currant fruiting occurs mainly on relatively young shoots - no older than four years. Every year it moves to the edges of the bush, and the branches gradually lose their ability to grow. Usually currants, both black and colored, bear fruit well for ten years or a little more. Then flowering stops - the bush is aging.

What to do with such a plant? The easiest way is to uproot and plant a new bush. But you can try to rejuvenate it. To do this, the plant is heavily thinned, removing all old and mossy branches and leaving only the youngest shoots. Sometimes they even cut it at the root in order to get a friendly growth next year. And, of course, it is necessary to feed the currants - with organic matter or complete mineral fertilizer.

When a healthy and young bush refuses to bear fruit, then most likely it is simply not suitable for this climate. This happens when currants are annually damaged by spring frosts, or fruit buds die in winter due to low frost resistance. The fact is that the southern varieties are not adapted to the changing weather conditions of the northwest. The buds begin to grow early and, frozen, can no longer bloom.

Another reason why a young and healthy currant bush may not bear fruit is the lack of pollinators. Although most varieties are self-fertile, sometimes there are those that produce only one or two berries without cross-pollination, and even then not every year. There is only one treatment here - it is necessary to ensure pollination in any way.

And finally, there are cases when young bushes grow well, have lush dark green foliage and huge annual growths. But no matter how they feed them, no matter how they water them, they do not begin to bloom. Most likely, such plants simply “fatten” - they endlessly increase their green mass due to excess nitrogen in too “fatty” soil. To force them to bear fruit, it is necessary to eliminate the cause that caused the nutrient imbalance, feed them with potassium and phosphorus, and monitor which fertilizers fall into areas close to the roots.

Lack of yield can also be caused by disease of the bush with terry. Signs of it are found during flowering. Sick flowers are characterized by abnormally narrow petals and overgrown pistils. The flower tassel becomes like a thin twig, covered with yellowish scales instead of berries. The leaves grow three-lobed and abnormally elongated. The disease is contagious and cannot be treated. Sick bushes must be uprooted and burned along with the roots.

Prevents the formation of berries and the defeat of currants with a glass case, as well as insect pests that eat away the pistils of flowers and young ovaries. According to some reports, even large forest ants, which have bred heavily on the site, can do this. It is better to fight them with biological methods, but if those do not help, you have to use stronger chemicals.

As a rule, there are no hopeless situations. If desired, fruiting can be restored in one way or another, especially if the variety is rare and valuable, capable of producing good and tasty berries.

Blackcurrant is a perennial shrub that annually pleases gardeners with not only tasty, but also healthy berries. Blackcurrant is rich in vitamins A, B, C, P, as well as sodium, potassium, phosphorus, iron, magnesium, pectins and organic acids. Needless to say, a handful of freshly picked currant berries contains an excellent supply of vitamins and minerals. If we are talking about the harvest, then from one hectare of land you can collect up to thirty kilograms of berries. Many summer residents know blackcurrant as an unpretentious plant and therefore expect a good harvest every year.

However, very often blackcurrant either completely ceases to bear fruit, or produces two or three berries from each bush. In the first year, this is normal, but in subsequent years, it is worth looking for the cause of such abnormal behavior.

Why blackcurrant does not bear fruit: causes and their elimination

1. Lack or excess of sunlight

Blackcurrant loves sunlight, but in moderation. Therefore, the gardener may simply not wait for the harvest, or he will be very, very modest. The same thing happens when currant bushes are planted in the sun itself. For planting, you should choose a shady place, the bushes should not be roasted in the sun from morning to evening, but scattered sunlight should fall on them.

2. Unfavorable weather conditions for blackcurrant

The shrub belongs to heat-loving plants, so the southern varieties of currants may simply not take root in the climate of central Russia. This can cause spring frosts to damage already delicate shrub buds. A plant that is not resistant to low temperatures may not produce berries this year. Often, severe spring frosts lead to the death of young shrubs that are not adapted to harsh climatic conditions. To prevent this from happening, you should choose those blackcurrant varieties that are suitable for a particular region.

3. Soil condition

Blackcurrant is very demanding on the composition of the soil. The shrub prefers to grow in loose, fertilized soil. The soil should be as moist as possible. Potassium salt and superphosphate are great for maintaining the mineral composition of the soil necessary for shrubs. However, one should not overdo it with fertilizers, because this can lead to excessive fat content of the soil and, as a result, a lack of yield.

4. Diseases and pests

Often, blackcurrants do not bear fruit well due to diseases and pests. For example, the wood ant, the bud mite, and the glass butterfly can interfere with the crop. The kidney mite can be recognized by the enlarged buds that appear on the shoots of the bush. If the grower notices this, the buds should be removed immediately. The glass butterfly is almost invisible, but it is able to make real moves for itself and greatly harm the shoots of the plant. Forest ants cause serious damage to blackcurrants: they are able to gnaw out the inside of a flower. You need to fight pests in a timely manner: destroy the damaged parts of the shrub, completely uproot the dead plants, plant onions and garlic in the aisles. In the most severe cases, the grower should apply chemicals.
