It is a tree that can reach a height of about 30-40 meters. In middle latitudes, the height of such a plant, as a rule, does not exceed 18 meters, while the trunk reaches about 50 cm in diameter. There are many deep cracks on the surface of the dark crust. The tree got its name due to the spectacular black color of the fruits, bark, and wood.<\/p>\n

This tall tree comes from North America. In this regard, the people often call it “Canadian nut” or “American nut”. The plant can be found in deciduous forests, while its range is quite extensive: from Massachusetts in the south to Florida, and in the west – to Minnesota and Texas.<\/p>\n
This plant is found throughout Europe. However, in the Scandinavian countries, it does not grow, due to the fact that there is a rather harsh cold climate. Black walnut prefers to grow on river and lakeshores, in the mountains, as well as in deciduous forests. The fact is that it needs moist soil.<\/p>\n

Black walnut is distinguished by the fact that its foliage has phytoncide properties. Phytoncides are able to destroy various bacteria in the air, due to this, it is purified. In order for such a spectacular tree to grow well, you should choose the most suitable place for it on your site.<\/p>\n
It should be remembered that if there is a high concentration of phytoncides in the air, this will lead to the death of not only pathogenic but also beneficial bacteria for the human body. In this regard, if you decide to plant several seedlings at once, then the distance between them should be at least 15\u201320 m.<\/p>\n

For the Canadian walnut to grow and develop within normal limits, the air temperature must be at least 10 degrees. However, adult plants are distinguished by their resistance to cold, they are not harmed by a decrease in air temperature to minus 38 degrees.<\/p>\n
The soil should be slightly alkaline or neutral. A tree growing on slightly acidic or acidic soil lags behind in development and is not able to properly prepare for the coming winter.<\/p>\n
Black walnut is distinguished by its moisture-loving nature. Quite often in Indiana, the root system of a plant is flooded. Often it is underwater for 4 weeks, but this does not harm the plant.<\/p>\n
For planting such a crop, it is not recommended to choose areas located near fruit trees. Also, birch cannot grow normally next to it, as well as Solanaceous (tomatoes, potatoes, and eggplants). The fact is that the foliage of the black walnut emits a toxic substance – juglone, which has a detrimental effect on plants that are in close proximity to it. After some time, such a neighborhood leads to the death of these plants. However, there are trees that grow beautifully next to the Canadian walnut, such as maple, linden, and hornbeam.<\/p>\n

Before proceeding with the direct planting of black walnut, you need to start preparing the soil on the site. For spring planting, the soil begins to be prepared in the fall. Within 6 months, the earth will be able to accumulate the required amount of moisture. It must be fertilized; for this, compost or humus is introduced into the soil (3-4 kg per 1 m2).<\/p>\n
When 1.5\u20132 weeks remain before planting the seedling, add soil to the prepared hole, which is mixed with 50 grams of potassium salt with 150 grams of superphosphate. Immediately before planting, the root system of the seedling is immersed for some time in a solution of a growth-stimulating agent.<\/p>\n
The size of the planting hole must correspond to the size of the root system. The surface of the near-stem circle of a planted plant must be systematically loosened, and the tree itself must be spud. To avoid excessive evaporation of moisture, cover the soil surface near the plant with a layer of mulch.<\/p>\n
