The tree is unpretentious to environmental conditions, but so that the crown is always bright and fluffy, when choosing a place for planting, they adhere to such recommendations:
- the site should be well lit by the sun - this contributes to the active growth of spruce and gives a rich color to the needles;
- young seedlings need to be planted at a certain distance from other trees and structures, since an adult specimen requires a lot of space;
- the soil should be fertile and loose, good moisture permeability - the ideal option is sandy loam or loamy soil;
- It is best to place seedlings on the north side of the buildings so that in the spring shoots and needles do not get burns from the bright sun.

Step-by-step landing instructions:
- Dig a landing pit about 60 cm deep. Its width should be such as to fully accommodate the roots of a seedling and an earthen lump around them.
- At the bottom of the recess lay a layer of drainage from broken brick or pebbles.
- Put the roots of the young spruce in the recess with an earthen lump. Sprinkle the pit with loose soil in half.
- Pour a small amount of warm water with a sapling to moisten the soil well. After absorbing the fluid, lightly tamp the surface of the soil around the trunk.
- Fill the landing pit to the very top with the remaining soil, tamp. Water the tree again with warm water.

Basic care rules:
- young specimens are watered only in the warm season with a small amount of water - the root system of conifers does not respond well to waterlogging and stagnation of water in the soil;
- after planting, the soil surface around the seedlings is mulched with peat or dry sawdust - this will help prevent weeds from growing and will allow moisture to be retained in the soil longer;
- adult specimens should be watered only during severe summer droughts, moistening the earth with a moderate amount of water;
- in March, top dressing is introduced in the form of a complex store fertilizer for coniferous crops - in this case, you must carefully follow the instructions on the package;
- so that the branches of young seedlings do not break under the weight of the snow cover, for the winter they are slightly pressed to the trunk with a rope;
- in the spring, the spruce is covered with agrofibre or a thin cotton cloth - this helps protect the crown and trunk surface from sunburn;
- tree formation begins after it reaches a height of 1.5 m - for this, dry branches are cut in early spring, young shoots are shortened, giving the spruce a regular conical shape.
