Distinctive characteristics of the species

Irga canadensis or canadensis is a tall shrub with 3-20 trunks, depending on the variety. The plant develops rapidly. Mature bushes grow up to 6 m, live up to 50 years. If the trunk dies off, a new one is formed. Most of the roots lie at a depth of 50 cm, some deepen to 1.5 m, the branches fall below 3 m. The diameter of the bush reaches 2.5-5 m. Shoots are actively rising from the roots.

Warning! On poor soils, the bush has a lot of overgrowth to search for food. Light fertile soils contribute to less shoot formation.

The spreading crown of fruit varieties with drooping branches resembles an umbrella. The trunks are picturesquely curved, with a smooth warm brown bark. Young shoots are bright, reddish. Ovate finely serrated leaves 5-6 cm long on short, 1.5 cm petioles. The leaves are pubescent, with a silvery sheen, burgundy in autumn.

Olga, 47 years old, Penza region

I wrote out two seedlings of Canadian irgi - the Smokey and Thyssen varieties. They are growing for the second year. For the winter, she wrapped it in spruce branches. The plants came out in the spring without any problems, twisted around in buds, dismissed the leaves. Next year there will be the first berries.

Irina, 50 years old, Pskov

At the exhibition, four years ago, I bought a seedling of canadian irgi. I don’t know the variety, the name was lost on the way. The tree has been bearing fruit for two years. According to the description, oval berries are similar to Pembina, the flesh is sweet. And there are no overgrowths either, only this spring there was one shoot. We will take care, we will grow in two trunks, and then, maybe, other shoots will appear. The plant grew up to 2 m, bloomed profusely, there are small ovaries.

Boris, 56 years old, Kirov

Irga Canadian planted only this year, but I have been watching the bush for six years, growing with relatives. A shoot dug up in the fall, wrapped in sacking, was dug in by roots in the garden. I spent a great winter. Now the bush is developing well, the branches are growing. This is the Smokey variety. Indeed, the berries of the variety are very tasty, they do not knit. From a tree of 10 trunks, up to 10-12 kg of berries were collected.
