Irga Canadian: description of varieties, planting and care
Canadian irga is a plant that definitely has a place in the garden of any gardener. It is not too whimsical, usually bears abundant fruit, can serve as an ornamental hedge and lives for fifty years.
Description
Irga Canadian is a fairly tall shrub, reaching a height of six meters. The tree has a large number of trunks, from three to twenty, the exact number of which depends on the variety. Irga is able to grow up to fifty years, and if one of the trunks dies, then a new one will definitely form. The depth to which the roots go varies from fifty centimeters to three meters. The diameter of the crown is in the range from two and a half to five meters.
By itself, the "cap" of leaves resembles an umbrella, the branches of which look down. The trunks are covered with a smooth bark of a pleasant brown hue and most often look curved. Young shoots appear red. The leaf length is approximately six centimeters, and the petioles are about one and a half centimeters. They are covered with silvery down and have the shape of a rounded oval, the top of which is much narrower than the bottom.
Each flower has narrow petals, the diameter of which is about two centimeters. One of the advantages of Canadian irgi is the winter hardiness of flowers - this culture does not die from frost if the temperature does not fall below -7 degrees.Buds begin to bloom at the end of April, and flowering lasts approximately fourteen days. Fruiting begins in the third year of the existence of the shadberry, but a large number of berries appear from the tenth to the thirtieth year of life. On one bush, the gardener collects from six to eighteen kilograms of shadberry - again, the exact amount depends on the variety.
The berry itself weighs only one gram, and its average width is sixteen millimeters. The fruit has a neat round shape and a sweet taste. You can harvest in the second half of summer. The maturity of the shadberry is easily determined by its color - ripe berries look dark purple, and unripe berries look pink. Blue is considered a transitional color. As part of the irgi, approximately twelve percent of sugar, 40% of vitamin C, one percent of fruit acids, carotene, as well as other necessary substances and vitamins are isolated.
The variety is not afraid of either drought or low temperatures - the shrub will survive frosts reaching -40 degrees. It is self-pollinating, which is very convenient, does not express special requirements for the condition of the soil, absorbs noise and is able to grow even in an urban environment. Among the shortcomings of the culture, there are problems with uprooting the plant and a long period of fruiting.
Variety overview
Thyssen is the earliest variety of shadberry, because gardeners begin to harvest already at the end of the first summer month. The berries themselves are quite large in size, the diameter varies from seventeen to eighteen millimeters. The taste of "Thyssen" is quite sweet, and sourness does not even spoil it, rather, it gives a "refreshing" effect. The height of the shrub reaches five meters, and the width is six meters.The only disadvantage of this variety of shadberry can be called the fact that, blooming early, it falls into the period of frost and does not always successfully tolerate them.
Variety "Smoky", on the contrary, it is considered the latest - it begins to bloom only at the end of spring. The height of the bush is four and a half meters, the width corresponds to it. From one bush, the gardener receives approximately 25 kilograms of sweet and intolerant berries. The diameter of one fruit varies from 14 to 15 millimeters, its flesh is tender and fleshy, and the skin is colored deep blue. To the pluses of the variety, you can add high resistance to numerous diseases.
"Krasnoyarsk" refers to late ripening varieties. The height of the bush varies from three and a half to four meters. Berries are harvested at the junction of July and August, and the diameter of one fruit reaches two centimeters. To taste, this irga is quite sweet and moderately sour. The winter hardiness of this variety is very impressive - it does not die in winter at a temperature of -40 degrees. In addition, the Martin, Prince William, Ballerina, Mandam, Rainbow Pillar and Starry Night varieties are popular.
How to plant?
Landing irgi takes place according to a fairly conventional pattern. Its period is determined depending on weather conditions, more precisely, climate. For example, in the Moscow region, irgu is planted in the spring, and in the south you can wait until autumn. The soil can be almost any, but it is better not to risk with wetlands. The place should not be in the open sun, but the irgu is allowed to be planted as an ornamental hedge.
When the gardener plans to harvest, then holes should be placed so that five meters of free space is maintained between them. The seedlings used should be smooth, without scratches, with fibrous roots. The best specimens are those that are a year or two old. The bottom of each well is covered with drainage. Its depth should reach half a meter, and its width should be approximately 60 centimeters.
The soil used is a mixture of humus, sand, peat and soil available on the territory. Fertilizers can be applied immediately, for example, 400 grams of superphosphate, 100 grams of lime, tidying alkali, and 150 grams of potassium sulfate. When planting a seedling, it will need to be tilted at an angle of forty-five degrees, and not deepen the root neck. After making the soil, the area is watered, and the area around the trunk is also mulched.
How to properly care?
Caring for the Canadian Irga is, in principle, quite standard. Effective cultivation of a crop is impossible without high-quality watering. As a rule, during the rains, the roots of the plant absorb moisture on their own, but if a drought occurs, then twice a month you will have to irrigate the beds on your own. Usually a small diffuser is used for this, and it takes from twenty to thirty liters. Watering ends with loosening and weeding, which contributes to a better transport of oxygen to the roots.
You need to feed the irgu somewhere two or even three years after planting with mineral and organic fertilizers. In early spring, about fifty grams of nitrogen fertilizer is usually applied to the area near the trunk, and after flowering, foliar top dressing is carried out. For this purpose, as a rule, about two grams of boric acid, copper sulphate and zinc sulphate are dissolved in ten liters of water. In the summer, organic matter is periodically introduced - mullein, litter or herbal infusions.In autumn, it is worth feeding the culture with 0.5 liters of ash or with a combination of 100 grams of superphosphate and 50 grams of potassium preparations.
Any fertilization ends with abundant watering.
In early spring, it is necessary to cut off the shoots and those branches that are already dying, damaged, or creating excessive crown density. During the year, it is also necessary to shape the crown, for example, cutting off young branches to stimulate the growth of the crown. At the end of autumn, all dried parts are also removed, fallen leaves are cleaned, and the soil is dug up. If the plant is mature, it is not necessary to cover it for the winter.
Reproduction of Canadian shadberry is carried out in several ways: using seeds, cuttings, layering, shoots or division. In the first case, ripe berries are collected on the most productive bushes, and seeds are extracted from them. Sowing is carried out in the fall under the film. If sowing is to take place in the spring, then the pre-seeding material will need to be stratified for about three months in fabric bags filled with moistened sand. In the event that it is decided to use the shoots, the procedure is carried out either in the fall or in the spring, when the young shoots are separated from the main bush.
Cuttings will need to be cut from late June to mid-July. The size of this part of the plant should reach fifteen centimeters, and it is selected from five-year-old or six-year-old branches directly from the top. The finished cutting is first rooted in greenhouses, and in the spring months it is already transferred to open ground. Working with layering, you will need to dig a bush, separate the long branches of the root system and place them in previously dug holes. Finally, it will be possible to propagate the irga if, in March, a suitable hole is dug next to the lower branches.Having placed a branch in the recess, it must be pinned and covered with earth.
Diseases and pests
Canadian irga often suffers from tuberculosis. You can determine this disease if you examine the shoots and leaves - they become bright red, covered with growths, and then wither. The damaged parts of the bush will definitely have to be cut and destroyed, after which the remaining parts should be treated twice with copper sulphate or one percent Bordeaux liquid. The interval between procedures should be ten days. As a preventive measure for the disease, gardeners are advised to remove crumbling leaves and cut off damaged branches in a timely manner.
Characteristic of this culture is a disease such as sulfur rot. On the berries of the affected plant, wet dark spots first appear, which then transform into a gray coating. In order to cure the irga, you will have to use ash or colloidal sulfur, which is sprinkled on both the plant itself and the soil nearby. The main preventive measure in this case is to reduce watering. We must not forget about the appearance of multi-colored spots, signaling a fungal disease.
Processing in this case is possible only with purchased fungicides.
To prevent leaf spotting, it will be necessary to treat the irgu with copper sulfate or Bordeaux liquid, but only until the flowers appear. Finally, often the branches begin to dry out due to moniliosis. In this case, the affected parts will have to be destroyed, and the next year, do not forget to treat the bush with copper solutions.
The main pests that affect the Canadian irga are leafworm, seed-eater, hawthorn, aphids and moths.As a rule, they can be destroyed only with the help of purchased drugs, and the culture can be protected by properly caring for the culture.
Reviews of gardeners
