Spruce spruce(Picea Pungens.), undoubtedly, the most famous and, probably, favorite plant For each gardener. Walked synonym ate spiny - spruce blueAlthough not all copies of this species have a blue color of needles. Surprisingly beautiful silhouettes of these firings decorate central parks and streets, as well as significant territories of urban buildings. For these beauties did not regret the place and planted on small dumart sites At six acres, wanting to see in his yard "New Year's Christmas tree", which later took half of the territory. At the end of the XX century. Spiny fir has become a symbol of success and prosperity. Therefore, today, many owners of large areas seek to fall on the maximum blue Frees.

Love for them is definitely deserved, it is a very spectacular and rather trouble-free plant. One of the advantages of this fir is high dust and gas resistance, which is why it grows well on lively car tracks, where all other coniferous trees do not survive. Blue ate is not as much as, for example, pines are damaged by pests. And they hurt much less often than the same spruce, especially when proper landing and care.

The natural range of growing spruce Blue is in the west of North America and extends from the southeast of the Idaho state south through the states of Utah and Colorado to Arizona and New Mexico. It grows most often in the mountain valleys at an altitude of about 2000-3000 m, located along rivers and streams, on moistened soil. The tree is very high, grows up to 35-40 m and reaches the age of 600-800, especially if it is in his homeland. It is better grows on a sublinous or sampling, enough fertile soil. Despite the fact that fir spiny enough shades, trees grown in the shadows look less decorative due to the loss of brightness of the needles and long distances between the branches of the branches. It grows at a young age slowly, and after 10 years the growth rate increases significantly. The plant moves very well a haircut and the molding of the crown that makes the spruce more lush.

Spruce barbed Glauca. - Picea Pungens Glauca

Like any popular view, a spiny fir tree has a variety of forms differing in height, crown structure, the length of the needles, the intensity of its coloring and other indicators. We will briefly focus on the most common decorative varieties and, of course, let us touch the possible problems of their cultivation.

Decorative varieties

The most widely used in landscaping is the form'Glauca.‘ . Under this name there are almost all high non-removal trees with a blue tint of needles. Krone is beautiful, symmetrical, conical. A spruce grows up to 15-20 m in height and usually has more than 30 cm of growth per year. The needles on the branches holds more than 3-5 years. Breeding both seeds and stalling. Very resistant to urban conditions. It has high winter hardiness and frost resistance. It is better to plant in large areas, since the little sections of spruce looks cumbersome.
‘Glauer Globoz'Sisaya spherical, – 'Glauca Globosa'. Very widely used in landscaping and loved by landscape designers, land owners. Compact, neat, blue dwarf shape spruce, which grows usually to 1 m high and up to 1.5 m diameter. It looks very decorative both when grown solitary and in a group with other plants. It looks original in the Glaude Globes', grafted on the strains of different heights.

'Hopsi.‘ – 'Hoopsii' . One of the most beautiful and blue forms of spruce spiny. Amazing silver-blue color is preserved and does not fade even in winter. Despite the greater value of this form, compared with the form 'Glauca', fir 'Hoopsii' It takes high demand, which is due not only to the beauty of this form, longer cheese, but also more moderate growth. Hopsi is growing slower, and it is more often used in areas as a "New Year's Eve." At the age of over 20 years, it grows up to 8-10 m in height. In young years, so that the curvature of the trunk of the fir, it is worth

it is aligned with a stick fixing the top of the plant.
‘Montgomery ' – ‘Montgomery ' . Dwarf, the slow-growing form of the spin, the annual increase of which is no more than 5-6 cm per year. Even after 30 years, the height of this form and the diameter of the crown – 1.8 m. The needles are very beautiful, silver-blue, up to 20 mm in length, long saved on the branches. Beautiful fir tree for landscaping.
For sitting on the site as a "New Year's Christmas tree" I would recommend 'Fat Albert', with a dense, cone-shaped crown, but not growing more than 3-4 m in height.

It is interesting to look at the dwarf shapes, which can be planted in rocaria, make a composition with other conifers, these are relatively recently derived forms as 'MRS. Cesarini ' (1981, USA), 'Lucky Strike' (1983, Holland), etc.
When landscaping the site should also pay attention to a fir with an unusual form of crowns, such as ‘Glauca Pendula ' , 'Glauca Procumbens'. We began to enjoy the deserved attention of the form with a narrow pyramidal crown and branches directed upwards: ' Aizeli Fastigiata '( 'Iseli Fastigiata' ), as well as ‘ISELI FOXTAIL.‘ (1965, USA) and ‘Blue Totem.‘ .

Thus, now there are many interesting decorative forms in the market, but by landing them on the plot, do not forget that, like any plant, they can suffer from non-oscillation or firing roots, bad soils, shrimp root, and landing, and The effects of disease and pests.

New grade blue fir Picea Pungens. 'Blue Diamant.‘ (‘ Blue Daimond ‘ - Blue diamond).
This variety, like most of the varieties of Eli Kolyaci led in America, in 1990, and quite recently appeared in European and in our nurseries. The variety is distinguished by very thin gentle checkeeper-blue chowlings and a smooth birefront shape and slow growth. For the year, the plant grows only 10 cm in height, a 10-year-old plant has a height of only 1 meter and a width of 0.6-0.8 m, so adult plants are very expensive. An adult plant reaches a height of 5-7 meters. The branches form the right dense tiers around the trunk from the earth itself to the top of the top, the plant is very dense and fluffy, has a natural beautiful form and does not need special molding. Prefers a sunny place draned and weakly acidic soil.

Planting ate glauing and care for her

This kind of ate prefers shaded places. For vital activity, she does not require a rich land. It can survive on poor sandy soils. Optimal for growth is considered soil mixtureconsisting of a delicate land, peat and sand in the 2: 1: 1 proportion. Before planted fir, in landing pit You need to lay out drainage, for example, from clay, broken brick.

Fir, which grows on fertile soil a more pronounced root system.

Caring for fir glauco is easy. It must be more likely to water hot summer, as well as trim dry and sick branches in a timely manner. Young seedlings for the winter are desirable to mulch a layer of peat or sawdust with a thickness of 6-8 cm.

This fir is well tolerating the cold winter and in general is unpretentious. It is perfectly mastered in any terrain: it can feel great in the arid region, and in a wet maritime climate.
