Blue spruce is a symbol of the states of Utah and Colorado. This beautiful tree is able to decorate any site. Among all coniferous varieties, it is considered one of the best, so it is often planted as an ornamental plant. In order for the blue fir to rejoice with its natural and unique beauty, much effort and time from the grower will not be required. If you know some rules of planting and reproduction of spruce, then for many years trees will be a real ornament of the farmstead.
Spruce blue: habitat
The natural habitat of these beautiful evergreen trees is North America. The plant is unpretentious and feels great on rocky soils or near mountain rivers. Spruce normally tolerates frosts and cold winds, partially tolerated by the shadow. Although, if you look at this beauty in a park or in a private courtyard, at first glance it seems that the tree is tender and even fastidious. In fact, in the wild it feels fine.
As mentioned earlier, the blue spruce is a coniferous evergreen pla
In young plants, narrow-conical crown, old spruce become cylindrical. The needles are rhombic in shape, in a cross section of 15 to 30 mm in length, the color of the needles varies from greyish-green to bright-blue.
Cones 5-10 cm long, 2 cm wide in closed state, 4 cm in open state, slightly cylindrical in shape, color varies from reddish to violet. Mature cone - light brown. Seeds spruce blue length of about 4 mm. The color is black with a light brown wing about 10 mm long.
The needles are markedly silvery, because of this "decoration" the tree got its name - blue spruce. Silvery not only gives the plant a special, one might even say aristocratic look, but it also helps to keep moisture and protects from polluted air.
The spruce grows relatively slowly. At the end of spring, a lot of golden-beige kidneys of ovoid form form on the tips of the branches. In natural conditions, where air is much cleaner compared to city streets, blue firs survive to 600 years. Real long-livers!
In which soil should a blue spruce be planted?
Seedlings of blue spruce perfectly tolerate transplantation and well take root in a new place, although some planting features still exist. The very first thing that I would like to say is that you absolutely can not plant blue spruce on the place where garden crops were formerly grown. Neglect of this rule can lead to the defeat of the roots of fungal diseases.
It is recommended to plant a silver belly in a mixture of coniferous soil, sand, leaf land and peat. To increase the acidity of the soil, you can add a little bit of ammonium sulfate. Spruce will perfectly develop in a fertile, weakly acid and well-moistened soil. If the soil is too heavy, then it is necessary to create a drainage layer consisting of pieces of broken brick or coarse sand.
Spruce blue - a plant that is light-loving. In the shade, the tree will also grow, but it can develop incorrectly and lose the beauty of the crown. Its formation will initially go wrong, so it is possible to bend and different defects. Therefore, it is recommended to plant spruce in areas that are well illuminated by the sun's rays.
For transplanting seedlings, fir is the best and safest time - the beginning of spring. Determining places for young plants, it is necessary to take into account the fact that in the future they will grow strongly. Then it will be necessary again to "move" the Christmas trees to a more vacant place or initially do this, given the size of the adult tree.
Plant the plants quickly and neatly. The root system of the fir-tree is arranged in such a way that it can not be left for more than ten minutes outdoors. The earth on the root must remain intact. The root neck is left on the surface, it is impossible to fill it with earth.
Perfectly grown fir tree blue from seeds. There are no special difficulties, just for three months before planting the seeds must undergo stratification at low temperatures. Sow the spruce seeds in the heated open ground. For twelve hours before planting soak in warm water. Such a simple method of reproduction of blue spruce has proved itself well.
Reproduction by cuttings
Blue spruce successfully propagated and cuttings. With this method it is necessary to adhere to high humidity and stable temperature. Therefore, propagation by cuttings is carried out in greenhouses and greenhouses. In order for the cuttings to become more comfortable, they are pre-treated with preparations that stimulate the formation of the root system. The method of propagation is not worse than seed propagation, just a special room is needed.
After landing the blue spruce, the root system requires special attention. If you overlook and do not water the plant in time, it will die, as its roots are too weak to resist the drought. Regular watering, especially in extreme heat, is simply necessary.
Spruce Spruce is recommended early in the morning and late at night. This rule must be observed so that the branches of the tree are not too warmed by the sun's rays. If there is a sudden change in temperature, then the plant can suffer greatly.
Young Christmas trees better mulch near the trunk. For this, a peat bark and bark are used. During the summer period near the trees it is necessary to loosen the soil to a depth of 7-9 cm and, of course, weed out weeds.
Spruce blue is a fairly patient and hardy plant, but like all other representatives of the green world, it has enemies with which it is necessary to fight in time. Pests can adversely affect the beauty and growth of a tree.
If the sprouts noticeably thicken, inside which the larvae of the aphid-hermes have hidden, then it is necessary to immediately clean the tree from the infected shoots and treat the plant using carbofos or fufanon.
If openings with resin or hollows with a diameter of about 5 mm are visible in the bark of the tree, then this is an "attack" of stem pests. In this case, it is recommended to treat spruce with systemic insecticides. This procedure should be carried out every spring after the snow has melted.
Sometimes on blue firs rust is formed. This problem manifests itself in the form of yellow-brown stripes on the needles. It happens that the needles turn yellow completely. The cause of rust can be a dark and damp place, where the "blue" beauty "settled".If the needles are too affected, then the affected branches should be removed immediately. With a small infection, the stem and needles are sprayed with fungicides for ten consecutive days.
If the spruce dries on one side of the branch and the needles fall, this means that the coniferous beauty suffers from the fact that it has little sun or is affected by some other unfavorable external factors.
Blue spruce at home
Blue spruce is undoubtedly very beautiful trees! At home, they are used to decorate plots, to create exotic compositions. In addition to the fact that the spruce gives people their beauty, it still protects the site from the scorching sun and strong winds.
Blue Spruce looks great in a solitary landing on the open sun. The original color of the needles is fascinated by the silvery transfusion bordering on the blue. If you "lodge" a few of these wonderful trees on your site, then such planting will look like a natural beautiful fence made of pine needles.
