Glauka spruce canadian
The name speaks for itself: this species of coniferous trees is American. Spruce is the main species in the formation of the Canadian taiga. A tree can grow at a height of one thousand five hundred meters. According to the climatic conditions of growth, it is an analogue of the Siberian spruce. Therefore, Siberia is a second home for Glauka.
In Latin, the name of the spruce means "gray". Although many spruces have decorative gray forms. But for the Canadian variety, such coloring of needles is the norm. Growing in its natural environment, spruce has a less bright color of needles than cultivated trees, and a greater height, up tothirty meters. The crown is dense, cone-shaped, up to two meters in diameter. In young trees, the branches are directed tangentially upwards, while in old fir trees they are lowered down.
Lives a long time, three hundred to five hundred years. Grows on soils of any composition, but prefers loamy soils with good drainage. Engelmann spruce glauca is resistant to Siberian frosts. Garden forms and varieties of Canadian spruce (there are many) reproduce vegetatively. The main method is rooting cuttings.
Short varieties are called snowy. Their growth in Siberia does not cause problems. But other varietal varieties need shading during the period of bright winter and early spring rays of the sun. This is especially true for conical trees.
Spruce Pendula Serbian
This is the most beautiful weeping tree species. Spruce Engelman Pendula reaches a height of twelve meters at the age of twenty years. It grows ten to fifteen centimeters per year. And ten years later its height is fifteen meters. The crown is wide, its diameter is one and a half meters. Flexible shoots hang down. Flat needles are green, with a whitish coating below, and up to two centimeters long.
Spruce prefers neutral soils and moderate moisture. Does not tolerate compacted soils and stagnant water. Therefore, it must be planted away from the accumulation of a large amount of groundwater. At the bottom of the landing pit, a layer of drainage with a thickness of twenty centimeters should be laid. To do this, you can use a broken brick orsand. For group plantings, the distance between spruce trees should be two to three meters. Landing pits are deep, fifty to seventy centimeters. When planting, the neck of the root does not go deep into the ground, it should be on the same level with the ground surface.
For better survival of seedlings, you can independently prepare the soil from sod and leaf soil, sand and peat. Two parts of the first two components are mixed and one each of the last. As soon as the planting is over, the seedlings are watered with plenty of water: forty to fifty liters in each hole. Simultaneously with irrigation, fertilizers are applied: nitroammofoska and rootin, respectively, one hundred and ten grams per bucket of water.

Each tree is watered with ten buckets of water. The soil in the near-stem circle should be loosened regularly to a depth of five centimeters, to prevent the formation of a crust, and for the winter it should be mulched with peat six centimeters thick. After a cold period, the mulch is not removed, but mixed with the soil.
During the vegetative season, fertilizers are applied twice. Spruces are pruned in exceptional cases, when their shoots form a hedge. It is better to leave this procedure at the end of May or the beginning of June, since at this time the active movement of the juice stops. He althy branches are not removed.
