Irga, or korinka (Amelanchier) - deciduous berry shrub or small tree, belongs to the Pink family and to the Yablonev family. In the natural environment, there are more than two dozen different species, most of which are found in the Northern Hemisphere.

Irga can grow on various land plots - on rocky, forest, meadow. Its berries have a pleasant taste and valuable composition, and the plant itself is highly decorative at any time of the year. In spring, the culture attracts attention with its unusual in color, numerous blossoming leaves with pleasant pubescence. Soon after, a magical transformation begins - the bush is covered with racemose inflorescences of a large number of fragrant flowers of pink and white hues. During the fruiting period, berries - "apples" are gradually gaining ripeness and play with a palette of cream, pink, purple, violet colors. With the arrival of the autumn cold, the leaves of the irgi again play with color shades, shimmering with yellow, orange, red and purple flowers.

Description of the irga plant

Irga is a long-lived plant that can grow for 60-70 years. It has many advantages - the fruits ripen very quickly and have useful and medicinal properties. Berries contain a storehouse of substances necessary for strengthening health. A small tree is not afraid of drought and frost, it is the best honey plant among many plants, does not require much experience in growing and caring. The only thing that gardeners consider a negative quality of irgi is a large amount of root shoots, which grows quickly and in large quantities.

The most popular and demanded types of irgi among gardeners are Olkholistnaya, Lamarca, Ordinary, Kolosistaya, Canadian.

Planting irgi in open ground

When to plant

You can plant irgi seedlings in early spring or autumn, but experienced gardeners recommend this procedure to be carried out in the autumn season.

The site should be open, with sufficient sunlight and warmth. With insufficient lighting, the culture will spend energy not on abundant fruiting, but on searching for a source of light, the shoots will begin to stretch. It is also very important that the groundwater does not run close to the surface of the earth. Such "neighborhood" will harm the root system of irgi.

The soil in the selected area can be of any acidity, and in terms of composition, fertile loamy or sandy is best suited. The more nutritious the soil in the garden plot, the less root growth will form and the more abundant the berry harvest will be.

Site preparation

It is recommended to start preparatory work in the spring months. First, it is necessary to thoroughly clear the ground from weeds and various parts of plants, and then dig it up about 10-15 cm deep. Shortly before planting, fertilizers containing potassium and phosphorus should be added to the soil. For each square meter, you will need about 40 g of top dressing.

Selection of seedlings

When choosing seedlings, it is important to remember that only young plants at the age of one or two years are suitable for planting.

How to plant correctly

First you need to prepare the landing pit. Its depth and width are about 60 cm. The soil (three parts) from the hole is mixed with rotted compost and river sand (one part each). A nutrient mixture of phosphate (400 g), potassium (150 g) and humus (1-2 large buckets) is poured onto the bottom of the pit, mixed thoroughly, then the prepared soil is poured from the pit with a mound and a seedling is placed on it. After the root of the young tree is positioned and spread out over the surface, you can fill the entire hole with soil. Having slightly compacted the soil, it is important that the root collar remains at ground level; it is not recommended to deepen it.

The first watering is carried out immediately after planting. Each plant will require about 10 liters of water. You need to wait until all the water is absorbed, the earth settles down a little, and then add some more soil mixture into the hole. The trunk circle is covered with humus or peat mulch, after which the first pruning is carried out. The length of each shoot after "cutting" should not exceed 15 cm.

Irga care

Minimal care for irga is another advantage of the plant over other horticultural crops. She can do well herself, but with any care she will certainly thank her with her bewitching beauty and numerous harvest of high-quality and healthy berries.

Watering

The root part of the irgi goes deep into the ground to a depth of three meters. This makes it possible for the shrub to provide itself with a sufficient amount of moisture. In addition, the culture is quite resistant to dry weather. It is recommended to water the berry plantations only on particularly hot summer days. The procedure is best done with a special diffusing watering can on the hose. Favorable time for water procedures is the second half of the day (after 16-17 hours). Watering is carried out not only in the near-trunk circle, but also on the crown in order to wash off the dust from the leaf mass.

The soil

It is better to take care of the soil after it has been moistened. All weeds must be removed at the initial stage of appearance, and the soil around the bush must be loosened regularly.

Top dressing and fertilizers

Plants will need additional feeding only 3-4 years after planting. It is recommended to use liquid organic fertilizers in the spring-summer season in the form of infusion on bird droppings. Each bush needs about five liters of fertilizer, which must be applied to wet soil after sunset. Dry top dressing is poured into the trunk circle and filled with water.

Transfer

Irga over the age of 5-6 years has a negative attitude to the transplant. Due to the roots deeply embedded in the ground, this process is considered quite laborious and is used only if absolutely necessary. The plant will have to be removed from the soil together with an earthen lump with a diameter of about 1.2 m and a depth of about 70 cm. After planting in a new place, the tree is watered and mulched.

Pruning

Pruning irgi for sanitary or thinning purposes should only be carried out when there is an urgent need for it. For example, there is no point in pruning shoots in tall varieties, because this can only be done at a young age of irgi. In subsequent years, it will be difficult to overcome the height even while standing on the stairs. The first "haircut" can be started from the second year of the seedling's life. A favorable time for this is the beginning of March. It is recommended to remove root shoots regularly.

Places of cuts on adult shoots must be treated with varnish-based paint.

Preparing for winter

At the end of the growing season after harvesting, you need to remove all damaged, dried and thick shoots, dig up the garden plot and apply fertilizer to the soil. The shrubs do not need any shelter for the winter months, as they feel great even in the most severe frosts.

Diseases and pests

Possible irgi diseases are gray rot, drying out of branches and phyllostic spotting. Rescue measures - urgent pruning and removal of diseased parts of the plant, treatment with Bordeaux liquid, copper sulfate and normalization of the irrigation regime.

Reproduction of irgi

Seed propagation

Freshly harvested seeds, extracted from ripe berries, are buried 1.5-2 cm into the soil, watered generously, covered with a thick layer of dry foliage or dry grass and left until spring. In spring, seedlings thin out and create favorable conditions for growth and full development. Seedling care consists of watering, applying fertilizers containing nitrogen, loosening the soil and removing weeds.

Propagation by grafting cuttings

Irgi cuttings are grafted onto a two-year-old mountain ash in the spring. A cut (3 cm deep) is made about 15 cm above the root collar. The junction of the scion and the stock is covered with tape, and the cut of the scion is smeared with garden var. Having planted the stock in a box with a sandy-peat substrate, the container is kept in greenhouse conditions until the desired result.

Propagation by green cuttings

Apical cuttings are used for this propagation method. The tops are cut into a length of about fifteen centimeters, 2-4 leaves are left, placed in a vessel with a growth stimulator for 10-12 hours, then washed and planted at an angle of 45 degrees in a greenhouse or greenhouse. It requires humidification from a fine spray, ventilation and a constant temperature of about 25 degrees Celsius. The root part is formed after 3 weeks. Cuttings are planted in a permanent place only for the next autumn season.

Reproduction by layering

Layers are buried in warm and sunny early spring days, after digging up and fertilizing the soil under an adult plant. The lower shoot is fixed in the groove under the bush, the top is pinched, watered. Rooting will take place before the fall, but it is possible to transplant the layers to a permanent place in the spring.

Reproduction by dividing the bush

The bush, extracted from the ground in early spring, is first removed from unnecessary and damaged shoots, and then divided into several parts together with the rhizome. Delenki are immediately planted in prepared pits.


Irga - gardening

More than 20 species of irgi are known. In our country, spike irga grows, round-leaved, abundantly flowering, Canadian.

All types of irgi are shrubs with a height of 3-5 m. The root system of the plant is superficial, lying to a depth of 30-40 cm. The leaves are whole, round or oval.

Irga blooms almost simultaneously with bird cherry - at the end of April - the first half of May. The flowers are white or cream, collected in a brush, resistant to spring frosts, self-fertile, good honey plants.

After planting by the offspring, the irga begins to bear fruit in the 2-3rd year, and when propagated by seeds - in the 4th-5th. Fruiting on last year's growths. Fruits are small, berry-shaped, spherical in shape, oval, flat-round, purple, dark blue or almost black with a bluish bloom. They ripen at different times, in mid-July or early August, so they are eaten in several stages.

Irga is relatively shade-tolerant. Most of its species have high frost and winter hardiness. They can be successfully cultivated practically throughout the Non-Chernozem Zone.

Irga is undemanding to growing conditions, grows well on soils of different texture, acidity and excessive moisture. Resistant to fungal diseases and insect pests. Irga is propagated by root suckers, dividing the bush, green and root cuttings, grafting on hawthorn and sowing seeds.


Composition and calorie content

Irga berry is a source of bioactive compounds. They contain 29 polyphenolic compounds: anthocyanins, phenolic acids, flavonols, triterpenoids, carotenoids, catechins, chlorophyll and tocopherol. one

In 100 gr. Irgi contain:

  • carotenoids - lutein, zeaxanthin and beta-carotene. Their content is higher in green berries 2
  • flavonoids... Relieve inflammation 34
  • ursolic acid... Relieves inflammation and prevents muscle wasting 5
  • vitamin C... There is more of it in irga than in grapes. It is a powerful antioxidant 6
  • vitamin B2... Participates in the formation of blood cells and metabolism.

The calorie content of irgi is 45 kcal per 100 g.


Preparing irgi for planting

Irga is planted as close to the garden house as possible so that the birds peck berries less.

Soil preparation:

  1. The territory is freed from weeds in the spring and kept until autumn under black fallow.
  2. If the site is initially clean, legumes are planted on it in the summer - they improve the soil, make it more structural, and saturate it with nitrogen.
  3. On clay soil, it is imperative to add humus - up to 8 kg per sq. m, and river sand - up to 20 kg per sq. m.


The use of irgi in garden design

Tall bushes are perfect for the formation of hedges, area zoning. And undersized species will become the backdrop for the flower garden.

Using several varieties at once, you can create a whole range of colors, from spring to autumn. In addition to the usual yellow, green and red colors, the garden will receive orange, purple, violet and malachite shades. Thanks to this, it is convenient to use the irgo to block unsightly walls of buildings.


Mittlider's narrow beds

J. Meatlider - a scientist from the USA, is the developer of a universal method of growing agricultural crops. Interestingly, it is effective in different climatic and soil conditions.

Advantages of the Meatlider method:

  1. The peculiarity of the soils does not affect the yield... Now you can not blame the lack of chernozems - narrow beds are filled with soil mixture.
  2. No relationship between harvest and climatic conditions... The method is effective in different regions - dry and cool summers. Vegetables growing in narrow beds are not afraid of frosts, morning dew, etc.
  3. The area of ​​the site is saved. Narrow beds take up little space but are very productive.
  4. Easy maintenance. It is enough to go to the garden a couple of times a week.
  5. Big harvests. They, as proved by the experience of farmers, are much higher than in an ordinary vegetable garden.
  6. Saving water. It requires 40% less than traditional cultivation.

If there are already high beds in the garden, they can be turned into mitlider beds without any problems. Above them, you can easily build a greenhouse from a film.

The width of the Meatlider beds is only 45 cm, and any length. The distance between adjacent beds is 90 cm. Experimentally, the scientist found that vegetables are as comfortable as possible on such beds.

How to equip the Meatlider beds:

  1. Stock up on tools and materials: a shovel, a hoe, stakes, a fertilizer container and twine.
  2. Mark the land for future beds. Mark the outlines with pegs and twine.
  3. On the sides of the beds, erect boards of earth 10 cm high. Between adjacent beds, trample the soil - for passages.
  4. Water the beds thoroughly and plant the plants on them. Potatoes are planted at 35 cm intervals, bulbous crops are planted at 5 cm intervals.

Mitlider was not an adherent of eco-farming, therefore he applied mineral fertilizers to the soil. However, his beds are great for organic gardening. Instead of "chemicals" they are fertilized with compost, liquid manure solutions and other organic matter.

Organic farming only at first glance seems more complex and less profitable. If you master ecological methods of working with land and plants, you can get good yields while reducing the amount of labor. At the same time, the output is absolutely safe products that do not contain harmful substances.
