Topping cherries: basic fertilizers and the rules for their application

Cherry, like any other garden crop, needs regular care, including top dressing. There are several rules that you need to familiarize yourself with before starting this event, as well as studying the fertilizers used and their properties.

The main types of fertilizers and their characteristics

To feed cherries, a large number of fertilizers are used. Gardeners successfully use both organics and minerals. Familiarize yourself with the main characteristics and the minimum and maximum dosage (more details are given in the table).

Do not forget that all fertilizers must be applied to pre-moistened soil.

Urea

Urea is used for root and foliar top dressing

Urea is a popular fertilizer used by many gardeners. Contains nitrogen (46%), necessary for the development of green mass of the plant. It is recommended to use in combination with potassium salt if you are carrying out root dressing. Depending on the age of the cherry, you will need 50 to 300 g per 1 tree for top dressing.

The best water temperature for preparing a urea solution is 80 ° C.

Urea is also used for coccomycosis. This dangerous fungal disease is very contagious and can affect not only cherry trees, but also other crops, such as apricot. For the prevention and control of it, 3-5% (30-50 g of urea + 10 l of water) solution is used. They need to wash the cherries in early to mid-October.

When the cherry is damaged by coccomycosis, its leaves turn yellow and holes appear on them

Superphosphate

Superphosphate is an essential component of autumn top dressing

Superphosphate is one of the most commonly used fertilizers by gardeners, with many beneficial properties. It contains a nutrient - phosphorus (20–50%), due to which top dressing helps to slow down the aging of the cherry bush, increase the taste of berries, and the formation of the root system. With a lack of phosphorus, the leaves of the plant turn purple (sometimes only on the reverse side) and become covered with yellow spots.

If the plant lacks phosphorus, then purple spots form on it

Simple superphosphate goes well with nitrogen fertilizers, double - with potassium salts. It is not combined with ammonium nitrate, chalk and urea, so take a break of 7-10 days between applications of these fertilizers.

100–150 g of substance is used per 1 m2.

Potash fertilizer

Potassium fertilizers must be used carefully to feed cherries, because cherries are sensitive to chlorine.

Potassium chloride and potassium salt are often used to feed cherries.

Potassium chloride

Potassium chloride is often used by gardeners to feed fruit trees. This fertilizer improves the growth and development of the root system, positively affects winter hardiness and drought tolerance, activates shoot growth, which increases productivity, and the fruits themselves become more sugary and fleshy.

Potassium chloride is available in various forms, and for feeding cherry it is better to choose granular (otherwise it is also called seeds).

Potassium salt

Potassium salt is also a source of potassium, which helps to improve metabolism and increase the immunity of the plant. Cherry has an average resistance to chlorine, which is part of this fertilizer, so carefully follow the dosage when feeding. No more than 40 g rely on a seedling, about 100 g on an adult tree.

Ammonium nitrate

There are several types of ammonium nitrate that can be used to fertilize cherries.

Ammonium nitrate, like urea, is a source of nitrogen necessary for the growth of plants, especially young ones. For feeding cherries, you can use simple ammonium nitrate (it can even replace urea), as well as ammonia-potassium, which can improve the taste of fruits thanks to the potassium in its composition.

The maximum dosage of this fertilizer is -150 g for a seedling and 300 g for an adult tree, if you want to use saltpeter instead of urea.

Compost

Compost is a popular organic fertilizer with which you can enrich the soil with useful substances. Since cherries require regular top dressing, you must be able to properly prepare such a mixture. In a container or on the ground, lay a layer of peat (10-15 cm), on it - vegetable debris (leaves, vegetable tops, straw). Pour the stock with a solution of chicken manure or manure (1 part of manure to 20 parts of water or 1 part of manure to 10 parts of water, insist for 10 days). On 1 m2 of the workpiece, add 400 g of ammonium nitrate, 200 g of potassium sulfate and 500 g of double superphosphate. Fill the blank with a layer of earth or peat (10 cm). Cover with foil. After 2 months, the pile needs to be shoveled, and after 4 months from the moment of preparation, the compost is ready for use. 5 kg is enough for a young tree, at least 30 kg for an adult.

Ash

Ash saturates the soil with plenty of nutrients

Ash is an affordable and useful fertilizer containing a large amount of substances necessary for the growth and development of plants. Ash is rich in potassium and phosphorus, and also contains sulfur, zinc, iron, magnesium and calcium. Feeding with ash or ash solution can improve metabolic processes, regulate water balance and increase winter hardiness of cherry trees.

Ash Application Description

Lime

In horticulture, lime is used not only for whitewashing, but also to reduce the acidity of the soil and saturate it with useful substances. So, calcium contained in lime helps cherries increase immunity, improve metabolism and strengthen the walls of blood vessels, which will beneficially affect the root system of the bush. Liming should be done once every 4–5 years, especially if you use organics for top dressing. For alumina, light and loamy soils, 400–600 g / m2 will be needed, for heavy, clay soils, 500–800 g / m2.

Signs of acidic soil are the appearance on the surface of green moss, horsetail, puddles with rusty water or light bloom.

In addition, lime is often used in the fight against coccomycosis. One of the control measures is whitewashing a tree. Composition of the mixture: hydrated lime (2 kg) + copper sulfate (300 g) + water (10 l).

Whitewashing cherries will help cope with coccomycosis

Dolomite

The introduction of dolomite into the soil will help reduce acidity, as well as fertilize it

Dolomite flour, as well as lime, is used to lower the acidity of the soil and improve its quality. The introduction of dolomite contributes to the saturation of the soil with nitrogen, phosphorus and magnesium, positively affects the development of beneficial microorganisms and helps fight insect pests. The application rate of 500-600 g per 1 m2.

If you need to reduce the acidity of the soil, then when choosing a suitable product, focus on the time of year: lime copes with oxidation more efficiently, but it can only be used in early spring or late autumn. Dolomite is used at any time of the year. In addition, it is recommended to treat the peeled soils with it.

Topping cherries: scheme and rules for fertilizing

So that top dressing does not damage the cherry, you must follow the rules for fertilizing.

Trunk circle

To care for cherries, you need to leave the trunk circle

In order to ensure the correct feeding of cherries, do not forget to make a trunk circle. A near-stem circle is a cultivated area of ​​soil around a trunk where some fertilizers are applied (for example, mineral salts). The introduction of other fertilizers (for example, organics or solutions), as well as irrigation, is carried out in the outer furrow of the near-stem circle. The width of such a furrow should be 20-30 cm, depth - 20-25 cm.

The diameter of the trunk circle varies with the age of the cherry:

  • In the first year, irrigate in a circle at a distance of 10-15 cm from the seedling.
  • In the second year, the near-stem circle will be held at a distance of 25–35 cm from the seedling.
  • In the third year, the distance will increase to 40-50 cm.
  • In the fourth and subsequent years, when the crown is finally formed, the borders of the trunk circle should coincide with the boundaries of the crown. Some gardeners assume that the diameter of the trunk circle is 1.5 times the diameter of the crown.

Watering and top dressing are carried out in the outer furrow of the trunk circle

Cherry top dressing by years - summary table

This scheme is universal and can be used in all regions.

Cherry age1 year2 year3 year4 year If you have fertilized in a timely manner, and your tree develops correctly (bears fruit, does not turn yellow before the time, etc.), then you can switch to a less frequent mode of feeding. To do this, it will be necessary to apply 300 g of superphosphate and 100 g of potassium chloride and 1 time in 4 years to organic matter (30 kg of humus or compost in 1 external groove) once every 3 years in the autumn near the trunk.

If the cherry grows poorly (weakly forms shoots, does not bear fruit, etc.) and it lacks nutrients, then annual feeding should be carried out for another 3 years.

Perform preventive soil liming once every 5 years.

If you use lime, first dig the soil, and then sprinkle the powder on the surface. Do not forget that you can use lime either in early spring or in autumn, around the end of September. Also, do not carry out the liming procedure simultaneously with nitrogen (urea) and organic (compost) fertilizers.

5-6 year7 year Cherry is considered fully fertilized and no longer needs annual feeding. 1 time in 2 years in the spring add urea and 1 time in 4 years to the organics in the same doses as for the 7th year after planting a seedling. Liming is carried out once every 5 years according to the same rules.
Spring periodPrepare the landing pit. Parameters: depth - 40–50 cm, diameter - 50–80 cm.
  • Feeding option No. 1

    At the bottom of the pit, add a mixture of potassium chloride (25 g) and superphosphate (40 g), after wetting the soil. Fill the fertilizer with a layer of earth 5–8 cm thick. After planting a seedling, fill the pit with the following composition: humus + upper fertile soil layer (1 part) + humus (1 part).

  • Feeding option No. 2

    At the bottom of the pit, add a mixture of potassium chloride (20 g) and superphosphate (40 g). After planting a seedling, fill the pit with the following composition: ash (1 kg) + manure or compost (3-4 kg) mixed with the earth extracted from the pit. Note that you can only use rotted manure, otherwise you risk damaging the roots of the seedling.

  • Top dressing number 1. It is carried out immediately after the snow melts. Add a solution of chicken droppings or manure into the outer groove of the trunk circle. Preparation: chicken droppings (1 part) + water (20 parts). Mix and insist outdoors 10 days; manure (1 part) + water (4 parts). Mix and insist in a warm place for 10 days. Dilute before use as follows: 1 part solution to 4 parts water. Do not forget to shed furrow profusely before applying fertilizer.
  • Feeding No. 2. It is carried out by the same means immediately after flowering. If you do not want to acidify the soil, then organics can be replaced with ammonium nitrate (consumption - 150 g of fertilizer for each seedling).
Starting from the third year from the moment of planting, the cherry begins to bear fruit, therefore, it requires frequent top dressing.
  • Before budding, add the following mixture to each square meter of the trunk circle: double superphosphate (20 g) + potassium salt (10 g).
  • After flowering, add 1 liter of ash to the outer groove of the trunk circle, after moistening the soil. You can also pour cherries with a solution of mineral fertilizers: potassium salt (2 tablespoons) + urea (1 tablespoons) + 10 liters of water; potassium nitrate (2 tbsp) + 10 l of water.
At the beginning and mid-April, add 150 g of urea to the trunk circle and dig over the soil.In the early to mid-April, pour the external grooves with a solution of ammofoski (30 g of the drug per 10 liters of water). Each tree should take 30 liters.In mid-April, add 300 g of urea to the near-stem circle and dig.
Summer periodNo top dressingNo top dressingSummer treatment should be carried out during the appearance and development of the ovary, as well as during the ripening of the fruit.
  • Perform foliar top dressing: dilute urea (50 g) in water (10 l) and spray the crown. Repeat the procedure 2-3 more times with an interval of 10 days. Processing is carried out in the evening or in cloudy weather.
  • To build a seed, feed the cherry with an ash solution (1 liter of ash per 10 liter of water). It is necessary to water the entire trunk circle. On 1 tree you need 20–35 liters.
  • In mid-August, feed the cherries again with ash in the same proportions or with dolomite (1 cup dolomite per 10 l of water). On 1 tree will leave 20–35 liters. After 5-10 days, you can fertilize the cherry with a potassium-phosphorus solution: potassium salt (1 tablespoon) + double superphosphate (2 tablespoons) + 10 liters of water. The dosage and method of watering are the same.
At the end of July - beginning of August, add 300 g of double superphosphate and 100 g of potassium sulfate to the near-stem circle.No top dressingFeeding is not carried out.
Autumn periodNo top dressing
  • Between the end of August and the beginning of September, add 5 kg of humus and 100 g of double superphosphate per 1 m2 under each tree into the external grooves.
  • In the period from mid to late October, dig a near-trunk circle and add 1.5 kg of ash, 150 g of superphosphate and 30–40 g of potassium chloride per square meter to a depth of 8–10 cm.
Option number 1

In the period from mid to late October, dig a near-stem circle and add 2-3 kg of humus and mineral fertilizers (100 g of superphosphate and 30 g of potassium chloride / m2) into it.

Option No. 2 (for acidic soil)

In the period from mid to late October, dig a near-stem circle and add 2-3 kg of humus to it, and 2 kg of dolomite flour into the outer furrow.

In mid-September, add compost or humus to the outer furrow at the rate of 20 kg per 1 tree and dig it up.Feeding is not carried out.In mid-September, add a mineral mixture to the trunk circle: double superphosphate (400 g) + potassium sulfate (150 g). Dig the ground.

At the end of September, fertilize the outer furrows, adding 40 kg of humus to each tree.

Some gardeners claim that the fertilizer applied during planting should be enough for the first 3-4 years of cherry life. In this case, it is recommended to pay attention to the length of the branches: if the growth is less than 30–40 cm annually, then the cherry should be fed according to the specified scheme.
