Blue spruce: growing and care in the home

Blue Spruce - a symbol of the states of Utah and Colorado. This beautiful tree is able to decorate any part.

If you know some rules of planting and reproduction of fir trees, over the years, trees will be a real decoration of the compound.

Blue spruce: 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 shade. Although, if you look at this beauty in a park or in a private courtyard, at first glance it seems that the tree is delicate and even fastidious.In fact, in the wild, it feels great.

Description

As mentioned earlier, the blue spruce is a coniferous evergreen plant that looks great both in summer and in winter. The height of an adult tree is about 30 meters, but there are beauties with a height of more than forty meters. The trunk diameter is up to one and a half meters, the bark is thin and scaly, dark brown in color.

Young plants have narrow-conical crown, old spruces become cylindrical. The needles are of a rhombic shape, in section from 15 to 30 mm long, the color of the needles varies from grayish-green to bright blue.blue spruce seeds

Cones 5–10 cm long, 2 cm wide when closed, 4 cm wide, slightly cylindrical in the open state, the color changes from reddish to purple. Mature cone - light brown. Blue spruce seeds about 4 mm long. Color - black with a light brown wing about 10 mm long.

Silver needles stand out noticeably on the needles, because of this “decoration” the tree got its name - the blue spruce. Silvery not only gives the plant a special, one might even say, aristocratic look, but also helps retain moisture and protects against polluted air.

Spruce grows relatively slowly. At the end of spring, many golden-beige egg-shaped buds form on the tips of the branches. In natural conditions, where the air is much cleaner compared to city streets, blue spruces live to 600 years. Real centenarians!

What soil to plant blue spruce?

Blue spruce seedlings tolerate transplants well and take root well in a new place, although there are some peculiarities of planting a plant. The very first thing I would like to say is that it is absolutely impossible to plant a blue spruce in the place where garden crops were grown before. Neglect of this rule can lead to the defeat of the roots of fungal diseases.

Silver beauty is recommended to be planted in a mixture of coniferous soil, sand, leaf soil and peat. To increase the acidity of the soil, you can add a little ammonium sulfate. Spruce will develop well in fertile, slightly 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.

Landing

Blue spruce -plant photophilous.In the shade, the tree will also grow, but it may develop incorrectly and lose the beauty of the crown. Its formation initially does not go as it should, therefore curvature and various defects are possible. Proceeding from this, it is recommended to plant spruce in areas that are well lit by sunlight.blue spruce

For transplanting seedlings ate the best and safest time - the beginning of spring. Defining places for young plants, it is necessary to take into account the fact that they will grow greatly in the future. Then it will be necessary to “relocate” the Christmas trees to a freer place again or to do it initially, given the size of the adult tree.

Plants need to be quickly and accurately. The root system of the spruce is designed so that it is unacceptable to leave longer than ten minutes in the open air. The ground should remain intact. The root neck is left on the surface, it is impossible to cover it with earth.

Seed propagation

Blue spruce from seeds is well grown. There are no particular difficulties, just for three months before planting, the seeds should undergo stratification at low temperatures. Sow the seeds of spruce in a heated open ground.Twelve hours before planting soaked in warm water. Such a simple method of breeding blue spruce is well proven.

Reproduction by cuttings

Blue spruce successfully propagated and grafting. With this method it is required to adhere to high humidity and stable temperature. Therefore, reproduction by cuttings is carried out in greenhouses and greenhouses.blue spruce seedlingsIn order for the cuttings to settle down sooner and better, they are pretreated with preparations that stimulate the formation of the root system. The method of grafting is no worse than seed multiplication; a special room is just necessary.

Care

After the landing of the blue spruce, the root system requires special attention. If you overlook the plant and do not water it in time, it will die, because its roots are too weak to resist drought. Regular watering, especially in extreme heat, is a must.blue spruce seed

Water spruce recommended early in the morning and late in the evening. This rule must be observed so that the branches of the tree are not too heated by the sun's rays. If a sudden change in temperature occurs, the plant can suffer greatly.

Young Christmas trees are better to mulch near the trunk. For this, peat compost 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, to weed.

Pests

Blue spruce is a rather patient and enduring plant, but, like all other representatives of the green world, it has enemies with whom it is necessary to fight in time. Pests can adversely affect the beauty and growth of the tree.

If the shoots were eating noticeably thickening, inside which the aphid hermes larvae hid, it is urgent to clear the tree of infected shoots and process the plant using karbofos or fufanon.

If holes with resin or voids about 5 mm in diameter are visible in the bark of the tree, then this is an “attack” of stem pests. In this case, spruce is recommended to treat systemic insecticides. This procedure should be carried out every spring after the snow melted.

Diseases

Sometimes on blue spruce rust forms. This problem manifests itself in the form of yellow-brown stripes on the needles. It so happens that the needles turn yellow completely. The cause of rust can be a dark and damp place, where the blue beauty was “settled”. If the needles are too affected, then the affected branches should be removed immediately.With a small infection, the trunk and needles are sprayed with fungicides for ten days in a row.

If a spruce on one side of a branch dries up and conifer needles crumble, this means that the pine beauty suffers because it has little sun, or some other adverse external factors affect its health.

Blue spruce at home

Blue spruces are undoubtedly very beautiful trees! At home, they are used to decorate the plots, to create exotic compositions. Besides the fact that spruce gives people their beauty, it also protects the site from the scorching sun and strong winds.blue spruce at home

Blue spruce looks great in a single landing in the open sun area. The original color of the needles bewitches the transfusion of silver, bordering the blue. If you "settle" on your site a few of these wonderful trees, then such a planting will look like a natural beautiful fence of pine needles.
