Reproduction, planting and caring for shrubs in the Moscow region
Culture is quite unpretentious. Reproduction is carried out mainly by cutting the spring pruning bushes. Rooting cuttings is not difficult even for novice gardeners. Proper planting and caring for shrubs in the Moscow region are presented in detail later in the article.
The main rule - the choice of a place for planting Japanese kerri - shrub prefers bright sunny places, without the influence of strong wind. In the penumbra may change the color of the foliage, a strong stretching of the shoots. Due to this, lost decorative properties. The soil must be sufficiently fertilized with organic and mineral substances. It is very important to dig a deep trench to a depth of 1,5 meters before preparing the landing site. A broken brick or coarse gravel is laid on the bottom with a layer up to 70. Then a layer of organic humus is laid down to 30. The remaining space is filled with planting soil. After this, the wells are prepared and the planting of Japanese seedlings is carried out with rooted and rooted cuttings.
Proper care for Japanese kerri includes regular watering (the soil should not dry out to a depth of more than 10 cm). Mineral supplements are administered every week with special preparations for ornamental and flowering crops. They are added to water for irrigation.
For reproduction should take the apical shoots up to 6 cm. They are cut off with a sharp shear and put in water with the addition of succinic acid tablets. This drug is diluted at the rate of 4 tablets per 1 liter of water, stimulates the formation of the root system. After the appearance of small roots cuttings go deep into the ground on a separate shkolke. From above they can be covered with small improvised greenhouses. In the fall you get ready seedlings. But they should be planted in a permanent place only in spring.
Landscape design: pruning and crown formation

- the second cut off those twigs, which strongly thicken the bush and interfere with the proper development of the culture;
- the last stage is pruning any and all remaining branches on очке of their length.
Young bushes in the second year of life are cut off completely at a height of 15 - 2 cm from the ground. Thus, a rich crown of the correct form is formed due to the formation of lateral branches.
In landscape design, Japanese kerrium is used mainly as a background culture of a horizontal range of landscaping. Both single and group landings look great.
