Currant leaves turn yellow what to do folk remedies. What to do if the currant leaves turn yellow Blackcurrant leaves turn yellow and dry

If the currant leaves turn yellow and fall off at the beginning of summer, the plant needs increased attention. Black and red currants are distinguished by unpretentiousness in cultivation, but improper care leads to problems. The plant is weakening, the leaves in advanced cases curl up. This entails a reduction or complete loss of yield. The main causes are pests or wrong conditions cultivation.

The article discusses the main causes of yellowing of leaves on currant bushes: pests, violation of the rules of agricultural technology or improper care. Ways to deal with the problem and preventive measures are given.

Causes of yellowing leaves in summer

Yellowed currant leaves in June are an occasion to carefully examine the entire bush. It is important to identify the cause as early as possible in order to save the plant. Often the “culprit” is rainy weather in spring or early summer. This results in a washout useful substances from the topsoil. Help solve the problem foliar top dressing: peat, potash and phosphate fertilizers.

There are several main reasons why currant leaves turned yellow:

  • violation of the rules of agricultural technology;
  • dry soil;
  • pests.

On the affected bushes, the leaves turn yellow, curl and fall off. Thus, the bush tries to survive by shedding foliage. Young shoots slow down growth.

Berries become too small and sour.

Pests

Currant glass box harms the plant at the larval stage. It is possible to detect it by cutting off the damaged shoot. Glass larvae resemble black dots on a cut. The easiest way is the spider mite - the leaves and shoots are covered with whitish threads.

Incorrect growing conditions and care

If there is no damage on the bushes, it is worth looking for other reasons:

  1. Dry soil or over watering. The lack of moisture is dangerous for the bushes, because root system is on the surface. With excessive watering, the roots begin to rot.
  2. The bushes are closely planted. Currant seedlings are located at a distance of at least 1 meter. This will provide enough sunlight and space.
  3. Flaw nutrients in the ground. Currant does not tolerate sandy and clay soils. The application of organic and mineral fertilizers will help to solve the problem.

So that moisture does not evaporate from the soil quickly, frequent loosening is necessary. Do this carefully, for fear of damaging the roots.

How to fight

Yellowed leaves even on one bush is a reason to immediately inspect all other plants. When it comes to aphid infestation, all the bushes are populated. Will prevent the problem regular check bushes. In dry weather, increased watering will be required. With a lack of nutrients, complex mineral fertilizers(1 tablespoon of potassium sulfate or superphosphate diluted in a bucket of water).

Insecticide treatment

Treatment with chemicals against insects is carried out only after harvest. You can not do this during the flowering or ripening of berries. To do this, all infected shoots will have to be cut and burned. Spray bushes with insecticide against leaf-sucking insects. Arrivo, Tsiperus, TsipI are effective. Apply according to the instructions for the drug.

If the plants are heavily infected, preventive treatment is carried out in the spring before bud break, and one more in early autumn.

Folk remedies

With a minimal infection of gall aphids, the bushes are sprayed with infusions of chamomile, tobacco, onion peel, dandelion leaves or yarrow. This can be done before harvest if urgent processing is needed. You will need to process, including the underside of the leaves. To prevent aphids and spider mites, it is recommended to plant tomatoes between the rows of currants. The phytoncides they secrete repel insects.

Prevention

Autumn prevention can prevent yellowing of leaves:

  1. Collect and burn all fallen leaves.
  2. In dry weather, the bushes are watered abundantly. Carefully loosen the dried earth.
  3. After trimming, cover the cuts with garden pitch.

When in the middle of summer, among the general growth and ripening of fruits, the leaves on the currant turn yellow, it is worth sounding the alarm. If the problem is not solved quickly, you can be left without a crop. Inspection of the fruit crop will help to correctly "diagnose" and carry out recovery. Timely adoption of measures will allow the shrub to quickly recover and generously endow the owners with ripe berries.

Causes of leaf color change

What should a gardener look for? On black and red currant sheet plates may turn yellow in cases of:

  • The appearance of pests;
  • Disease infestations.
  • Violations of cultivation technology;

The cause of the disease is identified by examining the bush and consistently eliminating signs of damage.

Pests

First of all, you should pay attention to the presence of pests. The presence of insects and their larvae can be the main reason that currant leaves turn yellow.

Diseases

In the absence of insect pests, various diseases can cause the appearance of yellow leaves in currants.

  • Sferoteka. Fungal infection of foliage, branches and berries. Formed white coating web-like. As the lesion increases, it gradually darkens. The affected areas turn yellow, dry and curl. Berries fall off. The disease "prefers" black currants, although it sometimes develops on red varieties. Very quickly becomes infected from a number of growing gooseberries. Severe neglect of the disease is indicated by visible black specks. In this case, the crop cannot be eaten. All affected branches are cut and burned in the fall.
  • Anthracnose. Leaf yellowing comes from fungal disease rapidly spreading over the entire surface of the plates. Begins with the appearance brown spots, then the affected foci turn yellow, the leaf plates twist and fall off. In red currant, the berries suffer additionally.
  • Spotting. Fungal disease, the source of which is unharvested from last year plant remains currants. Wind-borne spores infect the leaves of the fruit crop.
  • Rust. It is brought by cereal weeds. Red swellings at the bottom of the leaf, leading to its yellowing and death.
  • Terry. Viruses carried spider mites. The main signs: purple color and terry coating of inflorescences, elongated yellowing leaves, poor development or fall of berries.

Diseases can occur together or separately, so you need to look carefully and choose, if possible, universal ways fight against illness folk remedies or chemicals with a universal spectrum of action.

Other causes of yellowing and how to eliminate them

The reasons why currant leaves turn yellow may be errors in cultivation practices.

Cause How to eliminate?
Drought. Additionally, small roots die. Active watering, loosening the soil under the bush. 2 buckets of water per landing.
Increased humidity. Rotting of small roots. Loosening, normalization of watering.
What if the soil is sandy or hard, not too fertile? Top dressing. autumn season- rotted manure, fertilizers with potassium and phosphorus. In the spring - a liter of ash for each planting.
Excess peat, potash or phosphate fertilizers in the soil. Reasonable top dressing, especially on young plants.
Close proximity to other fruit plants. Leave between plantings 1 m of land or more.
Underdeveloped roots. Make a shaping cut. Leave 4-6 strong shoots. This will allow the plant to strengthen the root system.
Early planting of seedlings in spring. Return frosts and temperatures below 18°C ​​do not in the best way affect survival. It is better to plant in the fall so that the seedlings can take root.
Landing on a shady, swampy, windy area. Cultivation in the light, protected from drafts.
Age over 15 years. Periodically change old plants to young ones.

If there is enough water, but the leaves on the currant continue to turn yellow, there are not enough nutrients, especially nitrogen. The most important annual mandatory work: pruning, fertilizing, watering.

IMPORTANT!!! The annual amount of fertilizer to support one blackcurrant bush: 40 g of ammonium nitrate and superphosphate, 30 g of potassium chloride. In acidic soils, after 6 years, lime is added around the plant.

What to do with yellowed currants

Having figured out why currant leaves turn yellow, you need to start improving the fruit crop. You can fight pests and diseases with the help of folk remedies and industrial preparations.

Folk remedies

  • Infusion of garlic, dandelion (from roots and leaves), tobacco or onion peel - with laundry soap(1 piece per bucket of water). If you do spraying on currants.
  • solution of tomato leaves. Watered so that the plant does not turn yellow.
  • Dry mustard. Sprinkling.

In order to prevent - after flowering, before the formation of the berry mass, the plants are treated with an infusion of onion peel.

Disease treatment:

  • For 10 liters of water a quarter wood ash. Spraying with an extract is carried out in the spring. Dry dressing is acceptable.
  • Liter of fermented slurry cow dung for a ten-liter bucket of water.
  • From powdery mildew and other fungal diseases: a third of the volume of the mullein is poured with three liters of water, after 3 days it is diluted to a bucket. Treatment in early spring, after color reset and at the end of summer.
  • Spraying with whey solution: 1 liter of whey in 9 liters of water.

After picking the berries, they are treated with the same means for prevention.

Features of the destruction of some pests:

  • Spider mite - in the early stages of the appearance, it is enough to confine yourself to spraying or rubbing with fresh water.
  • Gall aphid - start the fight as soon as you notice that small tubercles appear on the currant leaves.

IMPORTANT!!! Since the currant glass is not afraid of chemical treatment, it is extremely important as a preventive measure to loosen the soil around the circumference of the bush in the spring and in the first days of summer. Be sure to burn all plant residues in the fall.

Use of drugs

In extreme cases, when folk remedies are powerless to overcome the disease, you can use chemicals. Treatment with insecticides, acaricides and other means is recommended at the end of the flowering period.

Name of the drug Sphere of influence Period of use
Decis, Kinmiks Yellowing prevention. From the moment of bud swelling to flowering.
Bordeaux liquid, Colloidal sulfur, Topaz, Fundazol, Hom. For any illness. Once a decade. Drugs can be alternated. From anthracnose - in early spring or 14 days after picking berries, on bushes that were sick last season.
Agravertin, Fitoverm Prevention. At the end of flowering.
Acaricides, insectoacaricides, including Forbid 4F and Envidor. From aphids and spider mites. Before color set, after harvest. Each sheet must be processed on both sides to avoid yellowing.
blue vitriol From powdery mildew and other fungal diseases. As needed.
Anometrin - N or Rovikurt. Karbos. From kidney moth. Strictly before flowering.

The general scheme for processing currants:

  • The first treatment is done before bud break.
  • Seating of thickened plantings.
  • Processing throughout the growing season.
  • Autumn burning of plant residues.
  • In dry autumn - abundant watering and deep, neat loosening.
  • Regulating and shaping pruning.
  • Preventive treatment with insecticides.

are finishing autumn processing digging the earth between the bushes. Be careful not to touch the root system. This leads to the death of pests that have settled there for wintering.

Maintain the requirements of agricultural technology! Spend on time preventive actions for the control of pests and diseases. Knowing why currant leaves turn yellow, try to prevent this from the first days of crop growth.

Currant (lat. Ribes)- a genus of plants of the Gooseberry family, which includes about 150 species distributed in Europe, North America and Asia. Russian name The plant comes from the word "currant", meaning "strong smell", and indeed, for the berries, leaves and branches of black currant, a strong peculiar aroma is characteristic. White and red representatives of the genus do not have such a strong smell. The first mention of currants in Russia dates back to the eleventh century, and the annals of the sixteenth century tell us that at that time blackcurrants were already grown in abundance in gardens near Moscow. Today, perhaps, there is not a single garden in which a bush or two of this fragrant, tasty and healthy berry would not grow.

Currant bush - description

Currant is a bush from one to two and a half meters high with regular palm-shaped three-five-lobed leaves with large teeth along the edge. Currant blooms with carpal inflorescences, consisting of 5-10 small flowers with five petals, five stamens and five sepals. Berries up to 1 cm in diameter ripen by the end of July. The currant bush can begin to bear fruit the next year after planting. Currant shade-tolerant, but develops better in well-lit areas.

Of the numerous plant species, black currant (Ribes nigrum), red currant (Ribes rubrum) and white currant(Ribes niveum), in Lately began to gain popularity and yellow currant. The main number of berries is formed on the shoots of the first, second and third years of life. Currant berries are a pantry of organic acids, vitamins, macro- and microelements necessary for a person.

Red leaves on currant

If there are red spots on the currant, most likely this is a symptom of the presence of a red gall aphid or anthracnose fungal disease, and we will talk about them later.

Plaque on currant

White bloom on currants is a sign of American or European powdery mildew, and brown bloom is evidence that you are dealing with advanced cercosporosis.

Currant dries

If your currant dries up, try to answer these questions: is it affected by pests? does it suffer from lack of moisture? how old is a currant bush? Sometimes at the end of flowering, you can find that the currant has dried up - not all, but several branches. The reason for this may be the currant glass case - a butterfly with lilac-black scales on the body and a wingspan of 2.5 cm, which lays its eggs in the cracks of the currant bark, and the white caterpillars that have emerged from them eat away the core of the branches, from which the currant dries.

Fight method- timely treatment with insecticides - actellik or karbofos. If the cause is a lack of moisture, then you yourself know what to do. But if your currant is more than fifteen years old, apparently, it's time to take measures to rejuvenate the bush - cut off the old branches so that the currant can grow new ones, and treat the cuts with garden pitch.

Currant falls

Currant leaves may fall off prematurely if the plant is affected by anthracnose, spotting or aphids. Read about how to treat currants for diseases in the appropriate section (below).

Anthracnose currant

In the middle of summer, reddish-brown spots of no more than 1 mm in diameter may appear on currant leaves. The red spots that have arisen on the currant gradually blur, covering the entire leaf. Then the leaves in the lower part of the bush turn brown, dry up and fall off, because the anthracnose also affects the petioles of the leaves. This fungal disease is most pronounced during the rainy season. To a greater extent, anthracnose affects red currants. Spores of the disease overwinter in fallen leaves, which is why it is so important to remove last year's leaves from under the bushes in spring.

It is necessary to start the fight against the disease as early as possible, for this purpose currants are treated with a solution of Bordeaux liquid at the rate of 100 g per 10 liters of water. Re-treatment is carried out after harvest.

Powdery mildew on currants

When in the middle of summer a white loose coating appears on young leaves, which then passes to berries and old leaves, then you are dealing with a fungal disease. powdery mildew, or a sphere library. Since it is mainly weakened plants that are affected by diseases, good care minimizes the risk of disease, but if the disease manifests itself, spray currant bushes with Fitosporin or a solution of the contents of one pharmacy bottle of five percent iodine in ten liters of water. If necessary, the procedure can be repeated after three days.

If your manipulations were unsuccessful, you will have to resort to treating the bushes with a solution of Bordeaux liquid, copper oxychloride (1 teaspoon per 5-7 liters of water) or a one percent solution of copper sulphate.

Rust on currant

Currants can be affected by two types of rust - goblet and columnar. Goblet rust looks like raised warts orange color on the leaves, and the columnar - like small orange dots. Goblet rust can be carried to currants by wind from a sedge growing near a pond, and columnar rust can get on currants from coniferous trees. Start the fight against rust by treating currants with phytosporin, and if this measure does not help, treat the bushes with fungicides (one percent Bordeaux liquid, for example). There can be four such treatments with a break between them of 10 days.

Currant pests and their control

Aphids on currant

Most often, gardeners have to deal with such a harmful insect as aphids, and very often readers ask how to get rid of aphids on currants. Among the enemies of the currant are two types of aphids - leaf gall and gooseberry shoot. The presence of the gall aphid is manifested in the appearance of dark red or yellow swellings on the leaves of the currant, depending on the variety of the gall aphid, and from this it seems that the leaves of the currant have turned yellow or reddened. Over time, the leaves darken, dry out and fall off.

The gall aphid on the currant feeds on the juice of its leaves, and in one season seven generations of these insects can change, each of which makes its destructive contribution to the destruction of your garden, because this aphid settles on any plants. The shoot aphid damages the young branches of the currant, they bend and stop growing.

How to deal with aphids on currants, how to treat currants from aphids? Immediately after detecting pests, spray the plant with a solution of actellik or karbofos in accordance with the instructions - these are the most the best remedies from aphids on currants. If necessary, repeat the treatment after a week or ten days.

Ants on the currant

Where there are aphids, there are ants - this is the law of nature. It is the ants that carry aphids to new, “nutritious” areas - to young ones. succulent shoots, whose juice the aphids feed on, and in the fall they carry the aphids into their anthills, in order to again bring their “herds” out of the aphids to graze in your currant in the spring. And no matter how you fight aphids, while there is garden ants, you will not achieve success, and every year the currant harvest will be more and more scarce. In addition, ants spoil flower beds and lawns, and their anthill grows every day, reaching a depth of one and a half meters or more, and if you, upon discovering the presence of these insects, do not immediately try to destroy them, then it will be much more difficult for you to do so.

There are many folk ways fighting ants, but none of them gives one hundred percent result. the only in an efficient way getting rid of ants is the use of modern highly effective food-based baits and gels. Their poisonous substance does not act immediately, but after a while, so that the worker ants can deliver it to the anthill and feed it to the larvae and uterus. These innovative means developed in Germany. You can buy them in online stores.

Fire on the currant

Moth butterflies emerge from the ground during the flowering of the currant and lay their eggs in its flowers. The caterpillars that have appeared eat away the currant fruits, braiding them with cobwebs. One caterpillar can ruin up to 15 currants. If the butterflies have already laid their eggs in flowers, you are unlikely to be able to change anything, but you can prevent the appearance of moths: in early spring, lay a ruberoid or linoleum around the currant bushes, and sprinkle the edges with earth so that the butterflies cannot appear from the soil where they wintered in the form of pupae. Remove the coating after the currant has faded.

Tick ​​on currant

Work with currant bushes begins in early spring, until the buds wake up and sap flow begins. First of all, you should carry out a "hot" processing of currants. It is carried out in order to prevent pests and diseases and to ensure the full development and subsequent abundant fruiting. Heat water to 80 ºC, and pour currant bushes from a watering can with a divider. ten liters hot water should be enough for three bushes.

After a hot shower, it is very desirable to prune currants - remove damaged and weakened shoots, slightly trim the tips of branches that have frozen over the winter, thin out the bush if for some reason you did not do this in the fall. When pruning, remove those branches or buds that the bud mite has infested. All trimmings must be burned, and sections with a diameter exceeding 8 mm must be treated with garden pitch. After that, you need to clean the area with currants from last year's foliage, in which the larvae of insect pests and pathogens probably overwintered.

Treatment of currants from diseases

In early spring, before bud break, spray the currant bushes and the soil under them with a two percent solution of nitrofen or karbofos - this will protect the plants from almost all diseases. After a while, for fidelity, treat the currants with Bordeaux liquid, and when the real spring begins and the currants grow, from time to time it is possible to spray the currants with foundationazole for preventive purposes.

Processing currants from pests

How to spray currants so that pests do not infect it? Yes, all the same karbofos or nitrofen, which perfectly cope with their preventive function and protect currants not only from diseases, but also from pests. The fight against bud mites can be carried out at a temperature not lower than 20 ºC, otherwise, after spraying, the bushes must be wrapped in polyethylene. Do not be lazy, otherwise you will not be able to avoid problems with a kidney mite. To prevent currant bushes from being harmed by moth, with the beginning of the growing season, lay a roofing material around the bushes, sprinkling its edges with earth. When flowering ends and fruits appear, the roofing material can be removed.

Processing currants in autumn

In the fall, you will need to do an annual pruning of currants. All branches older than five years are deleted, as they are no longer very productive, but take up too much space. In addition, you need to cut to a healthy part or completely all the shoots in which the glass has settled - they are easy to identify, they are wilted and dried up. If possible, remove all shoots infected with bud mites, covered with powdery mildew, all weak and too thin zero shoots to the base of the bush.

If you have an old bush, take care of its rejuvenation, just do not overdo it with pruning: if you need to remove too many old branches, do it in three stages, that is, for three years - cut off a third of the branches every year. And do not forget to process sections of thick branches with garden pitch, and burn the trimmings.

After pruning, it is time to carry out an autumn preventive spraying of currants with a two percent solution of karbofos or a one percent solution of colloidal sulfur. Spray generously on the soil under the bushes. Spraying should be carried out in warm, calm, dry weather.

After this article, they usually read

Currant is unpretentious shrub, which usually does not cause much trouble. But it happens that the leaves of the currant turn yellow, when there is still no talk of autumn. What to do in this case can only be decided after the causes of yellowing have been established.

Currant leaves may turn yellow at the very beginning of summer, because gall aphids drink their juice. This is a very common pest that feeds on leaf sap. fruit crops. The gall aphid settles on the underside of the leaves, pierces the vessels with its proboscis, in this place small swellings appear, painted red or yellow. The entire leaf then turns yellow, falls prematurely. The worst thing is that 7 generations of gall aphids can appear in a season, on such a scale the pest can destroy more than one currant bush, settle on other plants. It will be impossible to do something later, you need to fight at the first sign of its appearance.

They fight aphids with insecticides, and they can only be applied before flowering or after harvesting. The rest of the time, you can only destroy the affected areas of the bush. The processing of each leaf on both sides is carried out after harvesting, and then it must be repeated in the fall, when the aphid lays its eggs. It is advisable to carry out preventive treatment of bushes and the land around them in the spring even before bud break.

The spider mite is also very small, they learn about it only after they first appear yellow leaves, and then a cobweb on a bush. If you notice it in time, you can get by with "washing" the plant clean water and hydration in the following days. It is desirable to fight it by spraying the bush with garlic, tobacco or onion infusion with the addition of laundry soap. Spraying with dandelion infusion gives a good effect. If such methods do not help, you need to use special acaricides or insectoacaricides.

Yellowing of leaves, death of shoots can be caused by currant glass caterpillars, which feed on juice and even gnaw on young tender shoots. The terrible thing is that this pest is not afraid of any chemicals, it cannot simply be poisoned. For prevention, you need to carefully loosen the ground around the bushes in spring and early summer, cut and destroy the affected shoots ruthlessly.

These are not the only pests that encroach on currants. There are also bud mites and bud currant moth, due to the actions of which the leaves may not bloom at all. The currant borer is a bug that feeds on leaves, and it leaves its larvae to winter inside the shoots. Leaf sawflies most often settle on red and white currants, feeding on their leaves.

Video “Currant pests”

From the video you will learn about currant pests and methods of dealing with them.

External factors

Healthy strong currant bushes are less likely to be attacked by pests and disease infections. And if this happens, then they suffer much less than their weakened counterparts. But pests are not the only reason for the sudden yellowing of currant leaves. You can understand why currant leaves may turn yellow by analyzing the conditions for their growth, the quality of care.

The simplest and most easily eliminated reason is lack of moisture. dry hot weather bushes need watering, in its absence, the leaves will turn yellow, dry, and the fruits will grow small, they may even dry out before ripening.

Oddly enough, but the leaves can also turn yellow with an excess of moisture, then this will be evidence of wilting due to a lack of useful nutrients, in particular nitrogen. Currant loves moisture, but it grows well on light nutrient soils, if the soil is not very fertile, then you need to feed the plants more often. For the same reason, it is advised to plant currants away from other shrubs or trees, and leave at least 1 meter between the bushes - so they will have enough land and sun.

If you plant incorrectly formed bushes, then the leaves may turn yellow, wither due to an underdeveloped root system. As a rule, a young bush should have 4 - 6 developed shoots, a strong, well-developed root system. Young roots will not be able to feed more growing shoots.

Another reason may be a bush planted at the wrong time. In order for it to take root and begin to develop well, when planting, the soil temperature must be above +18 degrees, which may not be the case in spring. early landing. That is why experienced gardeners prefer to plant currants in the fall.

This fruit bush need to be grown in a bright place, protected from the winds, in nutrient soil. Every year you need to cut it correctly, apply organic and mineral fertilizers, make sure that there is enough moisture, especially during the fruiting period. Then the bush will be healthy, strong.

Video “Protection from pests”

From the video you will learn how to protect currants from pests.

Yellowing of the leaves, whether it be in the spring (for example, in May), in the summer (in June or in other months) can be caused by various reasons. The first of them is, of course, the wrong planting of the bush..

If you have not chosen a very good place for him, then he will not be able to fully develop in the future. So, try to find an area where the soil is fertile and loamy. And, of course, before planting, be sure to moisten it well.

dry soil does not like, as well, and the other extreme - swampy places. Not suitable for her and the area where the winds are constantly walking. So, be sure to choose the place for the currant, this is the basis of its successful development. Otherwise, her leaves turn yellow very quickly already at this stage.

Currant leaves turn yellow. What else could be the reason?

With a landing black currant You made up your mind and chose it, it seems to be correct, but all the same, her leaves turned yellow. What other factors can cause yellowing of the leaves in this berry bush?

Landing time

Often in the spring we are in too much of a hurry to plant different cultures and currants, including. If the spring is still too early, then the arrival of frosts should definitely be feared, and even severe frosts.

The low temperature clearly does not contribute to the good survival rate of still very young bushes. In addition, the kidneys in such weather suffer greatly.

In order for the currant to start growing successfully and quickly, it needs a temperature that is warm enough - about plus 18-20 degrees. That is why the bushes that were planted in the fall develop much better than the spring ones.

Errors in the formation of a young bush

When buying at all young plant it is important to choose the right one. A good, young bush should have strong stems and there should be 4-6 of them. In addition, the root system of the bush should also be strong and already well developed.

Good choice young bush this is very important, but it is even more important to plant it correctly. When you plant a currant, be sure to cut off all these shoots that it has.

So you will help the plant to strengthen its growth and it will be able to form new shoots that will be even better.

If this simple procedure is not followed, often a young bush simply cannot withstand the abundance of foliage on it. And, as a result, the leaves of the black currant first turn yellow, and then they pull whole shoots behind them, which simply dry out.

Few nutrients in the soil

So that the soil under the currant can fully provide it with the necessary substances, it should be maintained every year. This support, first of all, comes down to the competent introduction . For currants, they must be phosphorus, as well as nitrogen and potassium.

There is a certain standard that determines the ratio of organic matter to mineral substances in relation to one currant bush. It looks like this: 40 g of ammonium nitrate - the same amount of superphosphate and 30 g of potassium chloride. After 6-7 years with too acidic soil lime is added to it. At the same time, you need to do this around the entire bush.

or a fungus on a currant

In addition to yellowing of the leaves, when these factors affect the currant, its leaves also roll down into a tube, or, if it is a fungus, then small mounds form on them.

The leaf itself (the whole plate) becomes harder, with tubercles, and later such leaves simply fall off.

Basically, such diseases (yes, and many others) are the result of the use of improper agricultural practices. That is, again, you planted a bush in the wrong place, and fed it poorly.

At the old bushes , which have brought you more than one crop, the leaves turn yellow for a very simple reason - from time to time. 16-18 years is the period that is considered productive for a currant bush.

Although at proper care, that is, competent feeding, formation and timely pruning unnecessary shoots, this period can be extended up to 10 years.

What to do? A few simple folk ways

Here we will talk about how to prevent yellowing of the leaves due to . It is best not to wait for them to appear, but to scare them off competently. To achieve this, the gaps that always exist between the bushes can be "populated" with tomatoes.

Tomato tops are a good "weapon" against aphids, because it releases phytoncides, which no species of these insects can tolerate. It is most convenient to use tomatoes of low varieties for this.

If, nevertheless, you failed to save the currant from aphids, but its settlements are still small, then you can insist on chamomile, yarrow or, for example, shag with tobacco. When processing, do not forget about bottom surface leaves.

So, the leaves on the currant will not turn yellow if it is planted correctly and, in the future, such mistakes will not be made when caring for this berry bush.
