Fertilizing currant seedlings in spring. Blackcurrant - how and when to fertilize, fertilize the bushes

In order for the bushes to be healthy, and the berries to be large, juicy, to please the harvest, currants need watering and top dressing. It is also useful to loosen the plants, treat them from pests and mulch the soil. In a word, as always, the mouth is full of worries. We read about the main points of caring for currants - how to feed - today.

When is the liquid feeding of currants

the first time - when the buds open, growth and flowering begin;
the second dressing is carried out immediately after flowering. At this time, there is increased growth, and the plant "needs to be supported." The amount of growth depends on this, and consequently, the amount of yield;
it is good to carry out the third dressing during the period of pouring berries (June - early July). At this time, the need for a fruiting bush for phosphorus and potassium increases. Any complex fertilizers are suitable for top dressing;
after harvesting, before laying flower buds (end of July - August), it is very important to carry out one more top dressing - this will be the key to successful fruiting in next year. But during this period, nitrogen fertilizers are recommended to be excluded (they delay the ripening of shoots).

Depending on the composition of the soil in your area, the frequency of application and the amount of fertilizer will, of course, vary. The poorer the soil, the more it is required to enrich them.

The first dressing of currants in spring

Performed immediately before flowering. If you notice that shoots of one and a half to two centimeters have formed on the bushes, it's time to start feeding the soil! It should be mentioned that currants are fertilized 4 times a year. If you fertilized with phosphorus, potassium and organic matter in the fall, then it makes sense to use nitrogen fertilizers in spring top dressing: 15 g of urea, 37 g of calcium and 15 g ammonium nitrate. This is an approximate volume of feeding the root zone of one currant bush.

If you did not fertilize currants in the fall, then the best option spring top dressing will be organic. It is recommended to dilute the manure in a bucket of water, add 2 teaspoons of urea and then mix well. We add 2 liters of the resulting mixture under each bush and pour abundantly with water.

The second dressing of currants in the spring

It is carried out exactly 14 days after the first. During this period, the berries are already beginning to set, and it's time to sprinkle the currant bushes with manure humus with the addition of 2 teaspoons of potassium sulfate. In addition, fertilizing currants is no less effective by another method: a solution of 10 liters of water and 4 teaspoons of Berry fertilizer. One bush takes 3 liters of fertilizer.

Fertilizing currants in the spring with folk remedies

Currant loves starch, so potato peels or leftover bread are often used as top dressing. How?

In the spring, the peel of potatoes (1 liter) dried over the winter is poured with boiling water and kept for 2 hours under the lid. Fertilizer consumption: 3 liters per bush.
Another recipe: the peel and bread scraps are mixed with grass and left to ferment. Released during fermentation carbon dioxide beneficial effect on the development of bushes.
Banana peel is valuable as a source of potassium for plants. To prepare top dressing, the peel of 5 bananas is dipped in a 10-liter bucket of water and insisted for 2 days, after which they are watered.
Or you can not bother preparing solutions, but simply chop fresh banana or potato peels a little and dig under the bushes.

How to carry out foliar fertilizing of currants with nitrogen and micronutrient fertilizers

Currant responds positively to foliar fertilizing with nitrogen and micronutrient fertilizers. So, zinc promotes plant resistance to fungal diseases, boron affects the nature of flowering and fertilization, manganese - on growth, yield, sugar and vitamin content in berries, increases immunity, improves photosynthesis. Copper is part of plant enzymes, increases the intensity of respiration.

Foliar top dressing can be carried out twice a season. The first time they are fed in the flowering phase: 30 g of urea is taken per 10 liters of water, 8 - boric acid, 1 - zinc chloride, 0.5 - copper sulfate, 0.25 - magnesium sulfate and 0.25 g of potassium permanganate. The second top dressing is carried out in the green ovary phase. In 10 liters of water, dissolve 50 g of urea, 5 - boric acid, 1.5 each - copper sulfate, zinc chloride and magnesium sulfate, as well as 0.5 g of potassium permanganate. Foliar top dressing is best done in the evening or in the morning on dry leaves. In any case, you must first do a test spraying on individual branches. If there are no leaf burns, then after a few days you can spray all the plants.

Dosage of spring fertilizers for currants

When applying top dressing for currants in the spring, it should be taken into account whether this procedure was carried out in the fall. If the soil is not fertilized, then in spring period two procedures are performed:

a mixture of mullein, ammonium nitrate and water (one tablespoon of ammonium nitrate is added to one bucket of liquid with mullein);
phosphorus-potassium (for 10 g of potassium sulfate take 20 g of superphosphate).

If the soil received additional nourishment in the form of phosphorus and potassium in the fall, then ammonium nitrate should be used (the dose for one bush is 50-70 g).

A few recipes for spring seasonal dressing for currants:

10 liters of water add potassium sulfate (one tablespoon) and complex fertilizer(50 ml), 20 liters of such a mixture is enough for one bush;
a mixture of ammonium nitrate (60-80 g), superphosphate (80 g), potassium chloride (40-50 g) - ideal for sulfur soils;
superphosphate (30-40 g) is added to the slurry and diluted with water (this can be done several times).

Experienced gardeners warn that manure (mullein) should not be used to fertilize currants in a pure, undiluted form, as this may not help, but harm currants.

What to do if spring feeding did not help

With weak growth and slow development, currant bushes are additionally fed with solutions organic fertilizers after flowering and harvest. Organic fertilizers can be replaced with mineral ones: 15 grams of urea or 20 grams of ammonium nitrate should be diluted in 10 liters of liquid. You can also use superphosphate, potassium sulfate or ash. Furrows of 10 cm depth are made around the bushes and fertilizers are applied to them, after which everything is covered with earth.

Probably, there is no such summer resident who would not plant at least a few currant bushes on his site. Everyone knows about the benefits of these healing berries. By the amount of vitamins, minerals and nutrients black currant surpassed all berries known to mankind. But the culture itself is unpretentious and modest - it does not seem to require anything special. In summer, currants should be fed so that shoots and fruit buds grow and develop well. Currants can be fed with phosphorus fertilizer (phosphate rock with the addition of superphosphate) Currant bushes are sensitive to chlorine, so substances containing potassium should be avoided for their feeding, preferring potassium sulfate or wood ash. In our article we will talk about summer top dressing of currants.

When currants are fed in summer

In the first half of June, organic fertilizing of currants should be carried out. Experienced gardeners advise spending at least two more top dressings with liquid fertilizers in the summer. One - in early July, during the filling of berries, the other - after the harvest, when new ones are laid. flower buds, that is, in late July - early August. Top dressing after picking berries will provide good harvest currants next year.

Foliar top dressing of currants, which are carried out in June-July, are very welcome by specialists. For this use water mixture urea with trace elements. For 10 liters of water, take 20 g of urea, 5 g of boric acid, 3 g of potassium permanganate and 30 g blue vitriol. Boric acid, potassium permanganate and vitriol are stirred in a separate container, and then they are combined together and the plant is sprayed with this mixture.

Precautions when feeding currants

It is especially necessary to pay attention to the fact that currants purchased for bushes mineral fertilizers did not contain chlorine, this element has a bad effect on the plant. You also need to observe the measure in the use of nitrogen fertilizers. They have a good effect on the growth of the bush, but at the same time reduce the fruitfulness of the plant and make it more vulnerable to fungal diseases. Excessive nitrogen fertilizers for currants after harvest are especially dangerous, as they inhibit the ripening of branches, and this can lead to freezing of the bush in winter time. However, it is important to observe the dosage of any fertilizer, not just nitrogen, so that the currant roots do not suffer.

How to properly feed currants

In order not to harm the currant, every gardener should know how to properly apply nutrients. Nitrogen supplements they are usually applied in a basal way, since the foliage absorbs them somewhat worse.

Before top dressing, the ground around the bush should be dug up well and watered abundantly, otherwise fertilizers can burn young roots. For the same reason, it is impossible to lay out bird droppings directly into the trunk circle.

It is better to step back 20-30 cm from the stems and scatter fertilizer on the ground, and then cover it with a small layer of earth or mulch on top. Cow dung is applied deep enough. To do this, the rotted mass is laid out around the bush and the soil is dug up to a depth of 20–25 cm within a radius of about one meter.

Fertilizing currants in summer after flowering

Immediately after flowering and summer period experts advise using liquid top dressings for blackcurrants - organic and mineral. For organic dressings suitable diluted with water in a ratio of 1:10 infusion of chicken mint, diluted with water 1:4 infusion of liquid mullein or " green manure"- infusions of weeds, which is also diluted with water in a ratio of 1:10.

For mineral liquid dressings, 10 g of nitrogen, 20 g of phosphorus and 10 g of potassium fertilizers are diluted per 10 liters of water. You can use a complex fertilizer with a high content of phosphorus and potassium, using 20-30 g per 10 liters of water. Liquid fertilizer - both organic and mineral - is applied at the rate of 10 liters of solution for each bush. Feeding with liquid fertilizer after flowering is necessary to support the plant and get a good harvest. Liquid fertilizers are applied after good watering or rain in the furrows that make around each currant bush. After watering and fertilizing, it is advisable to mulch the soil around the bush.

Foliar dressing of currants in summer

Experienced gardeners recommend foliar fertilizing of currants with microelements in June-July. To do this, 5 grams of potassium permanganate, 3 grams of boric acid and 30-40 grams of copper sulfate are diluted separately in different containers, and then mixed in 10 liters of water. This solution is sprayed with currant bushes.

Liquid fertilizing currants in summer

In addition to applying basic fertilizers, blackcurrants are given liquid top dressing, which is combined with watering. Usually they are used during flowering (May), during the period of shoot growth (May, June), when pouring berries (June) and immediately after harvest (August), when flower buds are laid.

For top dressing, an infusion of mullein or slurry is used, diluting 3-4 times (a bucket of solution per bush); infusion of bird droppings, diluted 8-10 times (half a bucket-bucket of solution per bush). Sometimes it is difficult to get natural organic fertilizers, in these cases you can use ready-made preparations from the store, for example, “Barrel and 4 buckets”, “Top-roots”, etc.

Fertilizing currants in the summer with folk methods

Ash feeding. Pour half a bucket of ash with water 1:1 and leave for 2 days, dilute the resulting composition 1:10, consumption per bush 1-2 buckets of solution.
Starch. It is advised to dig under dried bushes potato peelings, but the process of collecting and drying cleanings is very laborious and long. You can use store starch - dilute 200 grams of starch in 3 liters of water, boil and dilute in 1 bucket of water, consumption per bush is 2-3 liters. The downside of this recipe is that such starch is poorly digested. The most acceptable way to use potato peels is to prepare an infusion from them. From the beginning of the summer season, put the potato peelings in a large bucket or barrel with a small amount of water, you can add chopped green grass and banana peels there, throughout the season, after 2-5 weeks the infusion can be used. Dilute 1:10 and water currant bushes at the rate of 1 bucket of infusion per bush.
Bread fertilizer. Bread crusts are poured with water from 5 to 10 liters and infused in a warm place for 2 weeks. It can be diluted from 1:10 to 1:3, depending on the amount of solution and its concentration.

What other care is needed for currants in summer

Watering plays an important role in the care of currants in the hot summer. Also keep clean between the bushes, remove weeds on time. Feed with organic fertilizers, along with watering. Inspect the bushes all the time, and if pests or diseases are identified, take action, but do not treat with chemicals three weeks before the berries ripen, get by folk remedies. When the berries begin to sing, they need to be collected individually and selectively - only ripe as they ripen.

Knowing how to fertilize currants in the summer, and conducting a preventive examination, you can get every year big harvest this berry.

Before laying a plantation for currants, you need to deeply cultivate the soil and add rotted manure or other organic matter to it. In poor areas per 1 m2, up to 15 kg of organic matter, 50-60 g of phosphorus and 30-40 g of potash fertilizers should be applied. On soils with an average level of fertility, the volume of potash and phosphate fertilizers can be reduced by a quarter, and on fertile lands halved. With the joint application of organic matter and mineral fertilizers, the rate of both is reduced by half. Can be used instead of potash fertilizer wood ash in the amount of 20-30 g per 1 m 2.

All types currants prefer slightly acidic soils with a pH of about 6-6.5, therefore, in the fall, when preparing the site, sour soil will have to be limed, evenly introducing 0.3-0.8 kg of lime per 1 m 2 of future plantings.

In each landing pit lay up to 10 kg of organic matter (compost, peat or humus) and 40 g of potassium sulfate.

After planting, the soil surface around a seedling of any kind of currant is mulched with humus, peat or peat-dung compost, spending up to 4-5 kg of material per bush. At autumn planting mulch layer can be increased.

When planting blackcurrant bushes in well-fertilized planting holes in the first year after planting, they will not need fertilizer.

Annual fertilization should begin 3 years after planting. For adult plants, fertilizers are laid along the projection of the crown of the bush, in the area where most of the roots are located.

On loamy soils with high level fertility, you can make organic, phosphorus and potash fertilizers once every 3-4 years, doing it in two doses (spring and autumn) or limited only to spring application. To do this, in the spring, 1 liter can of wood ash is scattered on the surface of the soil inside the perimeter of the crown of the bush.

Additionally, on loamy, sandy, sandy and peaty soils, summer top dressing, combining them with watering plants. First liquid root dressing give during intensive formation of ovaries. For it, you can use a solution of mullein diluted with water 2-4 times, spending 1 bucket of fertilizer per 1 m 2 of planting, or a solution of bird droppings diluted with water 8-10 times (0.5-1 bucket of solution per 1 m 2 of planting ). Additionally, during this period, foliar top dressing (spraying the leaves) is carried out with a solution of trace elements: 2 teaspoons of Uniflor-micro fertilizer per 10 liters of water.

Immediately after fruiting, you need to feed the blackcurrant bushes with potassium and phosphorus. To prepare a solution of 1 tbsp. a spoonful of potassium sulfate and double granular superphosphate is diluted in 10 liters of water. In dry weather, fertilizers are applied during irrigation. In rainy weather, it is best to scatter the fertilizer over moist soil and loosen it slightly along with the topsoil.

In August, a liter jar of wood ash is scattered over the surface of the soil inside the perimeter of the crown of the bush for the second time.

At the end of October, 1 bucket of fully prepared humus is distributed along the perimeter of the crown of the bush.

In each landing hole under the red and white currant contribute 8-10 kg of organic matter, as well as 150-200 g of superphosphate and 30-40 g of potassium sulfate or wood ash.

Nitrogen mineral fertilizers, if necessary, can be applied only after the full rooting of the bushes. If currant leaves in the summer in the first year after planting have light color, then in July the plants need to be fed with liquid nitrogen fertilizer: 12-15 g of ammonium nitrate per 10 liters of water (this volume is enough for 2 plants).

❧ The rate of lime meal to reduce soil acidity is determined separately in each case, based on soil analysis data. According to experienced gardeners and gardeners, the average consumption of lime flour is 150-200 kg per hundred square meters.

Bushes of red and white currants begin to feed from the second or third year of development. On medium-fertile soils, 60-80 g of ammonium nitrate, 80 g of superphosphate, 50 g of potassium sulfate are annually applied per 1 bush. It is advisable to apply nitrogen fertilizers from the kit in the spring before bud break.

If in the spring under 3-year-old white and red currant bushes per 1 m2 of plantings, 4.5-6 g of the active substance of nitrogen are applied, then by the end of the operational period of an adult bush, this rate should be increased to 9-12 g of the active substance per 1 m2.

Superphosphate and potassium are laid before flowering and during the period of active formation of ovaries, as well as in August after harvest. Set of certain types fertilizers can be replaced with 400 g of fruit mixture.

With annual mulching of the soil under the bushes with organic fertilizer (15 kg per bush), mineral fertilizers can be omitted.

In the fall, in the third year of the life of red and white currant bushes, it is desirable to add organic matter: about 5-10 kg of manure, humus or compost per 1 m 2 of plantings, planting fertilizers to a depth of 10 cm. It is convenient to combine this event with autumn digging soil.

Currant constantly needs nutrients, which it mainly consumes from the soil. From year to year, the amount of nutrients in the earth decreases, and in order to prolong the life of berry bushes, the quality of the soil has to be improved by applying fertilizers. During the season, it is recommended to feed currants 4-5 times, using both mineral and organic fertilizers.

The very first top dressing is carried out at the moment the plant awakens and the green mass is actively growing;
The second dressing is carried out during flowering;
The third top dressing falls on the period of formation and ripening of fruits;
Fourth, after harvest;
The fifth can be done when preparing the bushes for wintering.

Top dressing can be root or foliar. foliar top dressing carried out by spraying the bush, a weak solution of fertilizer.

Nutrients with this type of top dressing are absorbed through the leaves and get to the plant faster than with root top dressing.
When root feeding Nutrients enter the soil and are absorbed by the plant through the absorption of useful elements by the roots. The process of delivering nutrients to the roots takes time, and the bush does not receive them immediately.

For a healthy harvest berry bushes, it is recommended to alternate these two types of top dressing.

How can you feed currant bushes

On the Internet, there are a lot of tips and recipes for all kinds of dressing solutions with the percentage and weight content of all substances necessary for application, depending on the stage of the vegetative development of the bush. Remembering everything is almost impossible, and probably not necessary. The most important thing that beginner gardeners need to know is:

The composition of the first two dressings should include nitrogen.
Subsequent feeding should be carried out by eliminating or reducing the level of nitrogen elements (because nitrogen contributes to the active growth of green mass, and at the stage of formation and ripening of berries this is no longer necessary, because the bush should direct all its forces to the formation and ripening of fruits, and not active green growth).

The simplest compositions for feeding currant bushes

Specialty Blends fertilizers for fruit bushes. Purchased granular or liquid fertilizers for feeding fruit bushes (spring-autumn) are convenient to use. On the back of each package is detailed instructions on application, composition, terms and rates of fertilizer application.

Folk recipes:

Nitrogen-containing top dressing (spring);
Complex feed (summer - autumn).

Nitrogen is found in manure, compost, bird droppings.
1. The rotted manure is diluted in water 1: 4 and the bushes are watered. Fresh, pour water 1:1 and insist 2-3 days. The finished composition is diluted 1:10 and watered with the calculation of 1 bucket of solution per bush.

2. bird droppings diluted 1:12, the application rate is the same - 1 bucket per bush.
3. It is good to mulch the ground under the bush with humus or compost, throughout the spring-summer period.

Complex fertilizing currants

Complex top dressing should contain phosphorus, magnesium, potassium, etc. useful elements. For such top dressing, you can use ash, starch, yeast.

All of the above compositions can be used both for the root method of feeding, and for foliar. You should be more careful only with manure and bird droppings, their concentration should be halved.

At first glance, it may seem that the preparation of infusions is a long and laborious process, but this is not so, we lay the right ingredients in a bucket of water and put in a greenhouse. The cooking process will go on by itself while you go about your business.

Folk methods of feeding should be used in combination with mineral fertilizers, alternating them with each other.

Take care of the currant bushes and then they will surely thank you with a plentiful, juicy and very sweet harvest.

Its special value is unpretentiousness. But still, for large and large fruits, it is necessary to give the plant additional activators for growth every year. Therefore, caring spend in the spring and throughout the season.

When to feed currants in spring

Everyone Needs Extra Nutrients fruit plant. You can make them in the ground or spray them with foliage. In any case, the bush will thank you. It is important to do this on time and regularly.

Fertilizer for a bush can be different: organic, root and foliar. Fertilize in autumn organic matter, and in spring it is preferable to use mineral mixtures. Liquid feeding can be done in a year four times:

at the beginning of flowering and bud break;
at the end of flowering, when the plant begins to grow rapidly;
the beginning of July is the time when the berries are suitable;
when the whole harvest is already harvested.

Each of these feeding options has its own characteristics. You can not overdo it or add those elements that the plant in this moment Not needed.

What is fertilizing currants in spring

It is in the spring, at the time when the plant begins to actively grow and develop, it draws everything that is in the soil. Therefore, during this period it is important to do spring top dressing.
If in the fall you can skip this procedure, then in the spring you should never do this. In addition, how much work will be done in the spring depends on your autumn activity.

Important! If you have already fertilized certain substances in the fall, then they must be removed from the fertilizer mixture for the bush in the spring.

And save the soil two types of fertilizer: mineral and organic. It is important to know when and which of them the plant needs for normal development.

Mineral fertilizers

Fertilizing currants in the spring with mineral fertilizers is necessary for the reason that during this period the plant draws everything that the soil gives it to form buds and the flowering process, strengthen the roots, or, in other words, - development of the aerial and root parts of the bush.
Minerals are especially necessary for plants that do not get everything they need from the soil in the first year of their growth. Therefore, phosphorus is useful here, and. You will notice insufficient development by the weak growth of the bush.

fertilizers phosphorus-potassium should be applied together with others in a year or two, focusing on the condition of the soil. It is preferable to add them in the autumn, to prepare for the winter, but they will not interfere with the spring.
Potassium substances are used only those that do not contain chlorine. The best and most popular option is this. Fertilizing currants in spring with ash is especially necessary for sandy and light soils.

Mineral nitrogen fertilizers help the plant gain strength after winter and grow actively. If the soils are fertile, then they will not need nitrogen.

If you notice that the plant is not growing as progressively, and its leaves are a light shade of green, this means that they lack growth activators - nitrogen.

Important! You have to be careful with nitrogen. An excess of this substance harms the plant, increases the risk of disease, and reduces yield. The application of this fertilizer in summer will weaken the plant, its internal tissues and reduce resistance to upcoming frosts in winter.

- another variety simple options mineral top dressing for a bush in the spring.

Spraying the root system of the plant is made from a solution based on such fertilizers. The recipe is the following:

water 10 l;
boric acid - 2 g;
zinc sulfate and manganese, 2 and 5 g, respectively;
copper sulphate up to 2 g.

These substances are designed to replace or supplement mineral fertilizers for currants in spring, summer, and autumn. Of course, the best effect is noticeable when both options are used together, in correct proportions and at the right time.

Organic matter is best applied during the summer and planted autumn: humus, . These same products will help you when landing. They must be added to the soil, so that later you don’t have to think about how to fertilize the currant bushes in the spring of next year.
For one bush, you will need about 7 kg of organic fertilizers, which are buried in a hole.

For annual top dressing, if desired, replace mineral fertilizers, use any organic matter. Its volume is not small - up to 15 kg per 1 currant bush. Now you can choose:

alternate minerals and organics in a year;
combine two types of fertilizer, reducing the volume of each by 2 times.

Currant fertilizer potato peels- another interesting option organics. Its advantage is that potatoes contain a large amount of starch, which is perfectly absorbed by currants.

Regular starch, which can be bought in a store, is rejected by currants, but potato starch - loves. In addition, it is another source of potassium and other trace elements, vitamins, and minerals.

Did you know? Fruitcurrants, absorbing a rich infusion of potato peels, increase in size and become sweeter in taste. And it is possible to carry out such top dressing in a volume of 3 liters per bush three times a year: when the ovaries appeared, the berries ripened and the last fruits were collected.

Undoubtedly, potato peelings– the best fertilizer for currants. You can prepare a solution from 1 liter of frozen or dried peels, which are poured into 10 liters of water at a temperature of 100 degrees. The container must be insulated and left for three days, stirring constantly.

How to feed currants in spring

Before getting down to business, you need to understand not only the types of fertilizers, but also how to properly apply them to the soil without harming the plant.

Rules for feeding bushes

Fertilizing currants in the spring is carried out as follows:

need to fertilize evenly;
you need to localize the substance near the plant itself along the radius, which will slightly exceed the diameter of the crown;
the first two years, currants can bear fruit without top dressing, if it was introduced during planting sufficient the amount of fertilizer;
mineral substances are less active and cannot independently penetrate deep into the soil to the lower layers of the roots, which means that when applying such a fertilizer, you need to do grooves or holes up to 30 cm deep, located 40 cm from the plant in a circle, where to place mineral salts;
nitrogen compounds normally penetrate the soil, but when they are applied, they need to mix with earth;
organic fertilizer spread on the ground, around the bush;
for effective feeding need unite root and root (spraying) fertilization procedures;
for foliar feeding apply smaller amount mineral substance so as not to burn the leaves, and choose from those that are completely soluble in water.

Important! It is necessary to spray the plant with minerals in the dark, when the sun will not fall on the foliage. So the liquid remains on the surface of the leaves longer, and the likelihood of burns will be significantly reduced.

The use of mineral trace elements for spraying is what you can feed currants in the spring before flowering and after the ovaries are formed.

Stages of feeding currants

Throughout the life of this bush, it is desirable to monitor its cleanliness and health, improve the condition of the soil, prepare for winter and give useful substances in the spring.
Therefore, top dressing should be carried out in several approaches, discussed below.

First dressing

Consider how to feed currants in the spring with or without autumn fertilizer. So, if in the fall you introduced phosphorus, potassium and organic matter, then in the spring it is only up to nitrogen.

That's what it is first stage top dressing. When the shoots begin to actively fill the branches of the bush (their length should reach 2 cm), you can get down to business. nitrogen fertilizer- this is:

and, 15 g each;
37 g of calcium nitrate.

These substances are diluted in water until completely dissolved. The proportions are based on one bush. If you need to add other salts, then their amount should be within:

phosphorus - 60-100 g;
potassium - 30-40 g.
