Spruce prickly silver

Spruce prickly silver

This is the name of a coniferous tree native to North America. Spruce, like most conifers, is well adapted to life in the shade, and drought is not an obstacle for it. It grows on loamy and sandy loam soils, reaches a maximum height of 40 meters (cultivated - 25), lives for almost 100 years. This tree can be planted with cuttings and seeds.

The spruce genus consists of many representatives, but the silvery herringbone is the slimmest and most beautiful of all. In addition, it is unpretentious, perfectly tolerates severe frosts and air pollution, and is resistant to snow drifts. With these qualities, she far surpasses all her "relatives". In the wild, Christmas trees live alone and in small groups. Most often found along rivers and on the northern mountain slopes of North America (in the western regions). Sometimes mountains are their habitat (height - 2-3 thousand m above sea level). The evergreen prickly silver spruce tree is considered one of the most valuable species, it is equally beautiful at any time of the year.

Description of the prickly silver spruce

The silvery spruce has a symmetrical, pyramidal (cone-shaped) slender crown with a diameter of 6 to 8 meters. Flat branches (paws) on it are located tightly, in horizontal tiers, their usual state is low-slung (the older the tree, the lower). Crown color - gray-blue. The most beautiful and popular are the varieties with the highest content of "silver" in the color of the needles. Certainly a bluer shade in cultivated trees (thanks to constant selection). It is interesting that when the shoots stop growing, the intensity of the gray-blue tint decreases, the needles acquire the usual green color.

The shade of young needles is pale green with a light white bloom. 3 cm sharp needle-shaped needles have 4 edges at the base. The trunk of a silvery herringbone with brown-gray bark resembles a straight column, its diameter is about 1 meter. Occasionally there is a 2 or 3-stem tree. The older the tree, the thicker its bark (about 3 cm). The old tree is also different in that its bark is roughly flaky. As for the spruce shoots, they are short, naked, strong, their color is orange-brown, turning into gray-brown with age. The shape of the hanging cones located at the very top of the crown is cylindrical. At first they are green, but when ripe, they acquire a chestnut brown color with a shine. At the edges, the cones are overgrown with jagged scales. The spruce grows annually in growth from 12 to 15 cm.

Planting and caring for a silver spruce

Spruce will grow best in a slightly shaded area. For a tree that is not too whimsical to the soil, it will be more pleasant to have a fertile soil, in which the formation of deeper and stronger roots is logical. Attention! When transplanting a plant, do not overdry the root system, compact and trample the soil! Spruce is afraid of nearby groundwater, therefore, if there are any, you cannot do without "soft" drainage (crushed stone and geotextiles in the soil). The neck of the root should be at ground level. The most acceptable acidity for the soil is 5-4.5.

As already mentioned, a silvery herringbone is planted with both seeds and cuttings. The planting hole should contain turf (2 parts), peat (1 part) and sand (1 part). It would be nice to add nitroammophoska (100 grams) to the soil. If the summer is hot and dry, young trees are watered once a week - a bucket of water for each plant. Silver spruce, unlike ordinary spruce, tolerates drought better. The soil under the seedlings is loosened shallowly - 5-7 cm is enough; when mulching, 5-6 cm of a peat layer is applied, which is then mixed with the soil, but not removed.

Only dry, broken and diseased branches are cut off. Trees used for hedges need radical pruning. They ate hardy adults, but the needles of young animals need to be protected from late autumn and early spring frosts. The first 2 after planting a year for the winter, the soil under the trees is mulched with sawdust (6-8 cm layer) or peat, adult trees do not need this.

Varieties of silver spruce

If the territory of the estate or private household is small, it will not be good for wild trees, but for varietal Christmas trees, varied in color, height and shape of needles. Blue-gray and silver-gray varieties are very popular among gardeners.

The most famous - prickly blue spruce... It is high (about 10 m) and has a beautiful conical crown. The needles of this tree are tough, their color is blue-green to silver. With growing up, the needles acquire a bluer tint. Blue spruce is planted in single specimens; it is not picky about soil and moisture. Very often it is she who acts as a New Year's symbol.

Koster - a common variety of spruce with silver-blue needles. The crown is conical, the height of the tree is approximately 7 meters.

The lightest needles in the variety Hoopsii... Its unique feature: in order to get a beautifully shaped crown, in the first years, a young tree is necessarily tied up.

Spherical 2-meter Christmas trees are very beautiful. There are dwarf and ground cover forms of silver spruce. The dwarf spruce is a tree with blue needles. It is no more than a meter tall, with a dense crown. There is a blue pillow-shaped spruce. Its height is only 50 cm, and its width is 70 cm. The young grows up crimson cones, which are located at the ends of the shoots. Such spruces look great alone and in different landscape landscapes (in rockeries, on alpine hills, etc.)

Where does the silvery spruce grow?

A silvery beauty from North America. This tree is a symbol of the states of Colorado and Utah (USA). It tolerates pruning well, making the crown thicker. Therefore, the herringbone often acts as a hedge. To create beautiful landscapes, the use of its decorative forms is suitable. Landscape designers are especially fond of the gray-gray form, which is familiar to us as silver (blue). It was bred from a specific population of an initial region in its natural range. There it coexists with bluish-green and silvery-green forms. This type is widely used for landscaping the territories of industrial enterprises.

At the age of 30-40, the silvery spruce enters the time of its highest flowering. At this age, it has the most intense color. Herringbone is not only a beautiful, but also a very useful tree. The prickly beauty, for example, serves beauticians: they often use the substance hydrolat, which is the water-containing part collected after decanting from the distillation apparatus. This powerful antiseptic and wound healing agent is recommended for the care of any type of skin (combination and oily skin as well).

Colorado spruce 'Glauka', description, photo, growing conditions, care

Spruce prickly ‘Glauka’ pine family. Homeland - North America where it grows in the Rocky Mountains at an altitude of 2000-3000 m above sea level. Spruce prickly ‘Glauka’ the most decorative of fir trees.

Tree, up to 15 - 30 m high, with a conical crown. The bark is gray-brown, thick, furrowed. Young shoots are yellowish-brown or orange-brown, glabrous, tough.
Male cones are brownish-brown, female cones are red, turning green when ripe, and then turning brown. Blossoming in May - early June.

Mature cones are cylindrical, light brown, 5-10 cm long. Ripen by September of the same year. Until the next fall, they usually hang on the tree, even after the seeds have spilled out. Seeds are 2 mm long with a short yellowish-brown wing.

The needles are green or bluish, 2-3 cm long. It differs from other spruces by the long protruding tetrahedral very sharp needles, the color of which can vary from green, blue, or dove-gray to almost white. The color depends on the wax coating on young needles, the thickness of which is different for different forms of spruce. By winter, the plaque gradually disappears, and the crown changes its color to dark green, and the needles become more rigid.

Spruce prickly ‘Glauka’ grows slowly. Possesses phytoncidal, air-ionizing properties.

It is to this type that most of the decorative forms, the so-called blue or silver spruce, belong.

Life form: Conifer tree

Crown: Conical, dense.

Growth rate:Fast. Annual growth is 30 cm in height and 15 cm in spread.

Height 15 m., Crown diameter 8 m.

Fruits: Cones, oval-cylindrical, brown, 5 to 10 cm.

Needles: Needle-shaped, hard, sharp, steel-bluish.

Decorativeness:Spruce prickly ‘Glauka’ decorative primarily due to the beautiful shape of the crown and the color of the needles.

Using: Spruce prickly ‘Glauka’ Single plantings, decorative groups, hedges.

I bought a spruce in the five two weeks before the new year. It cost 200 rubles. Was in a beautiful New Year's cardboard box in a flowerpot with a deep tray. Height 23 cm.

I was struck by the appearance of the spruce - a thick trunk, and on it there was not just a spruce, but a real dwarf tree. Plant in the appropriate pots and the bonsai is ready!) Naturally, I did not do this, because the tree almost jumped out of the pot in which it grew. And I immediately transplanted a larger pot into a pot by transshipment, since the roots are advised not to disturb. My land is "universal". But such soil sometimes needs to be "acidified" with water with the addition of citric acid.

First of all, it is worth noting that this plant should grow in nature, and not at home in a stuffy apartment. It's up to you to decide. You can (like many) decorate it and throw it away after the holidays. You can leave it at home and try to grow it at home. The best option, of course, is to transplant the spruce into natural conditions in the spring. So she has more chances for adaptation and further life for more than one year.

If you decide to leave it at home, then here are some tips to help the plant and prevent it from quickly dying:

1. In winter, keep the spruce in a cool place. It can be near the balcony door or on a cool windowsill.

2. In the summer, it is advisable to take it out to the loggia in the corner, where the scorching sun will reach at a minimum.

3. In dry air, spray the plant, otherwise the needles will crumble.

4. Don't forget to water! The ground should always be slightly damp!

5. Once a month, you can feed with fertilizer for conifers.

Well, that seems to be all the main thing that you need to know if you have purchased or are just going to Spruce Konik.

Growing conditions for silver spruce

Almost all varieties of prickly spruce require identical conditions. It must be remembered that conifers cannot be planted in the place where horticultural crops were previously grown. This can lead to the defeat of the root system by fungal diseases and destroy the plant.

Seat selection

Spruce grows best in a well-lit area. In the shade, the tree can bend and lose its decorative effect. Although the tree is a shade-tolerant and unpretentious tree, you need to plant a seedling in a mixture consisting of coniferous and leafy soil, peat and sand. The optimum soil acidity for spruce is 4.5-5 pH. To increase it, it is recommended to add ammonium sulfate. If the soil is heavy, you need to provide a drainage layer using expanded clay or broken brick.

Planting a seedling

Young spruce should be planted quickly. Its root system cannot be outdoors for more than 10 minutes. At the same time, it is necessary to try to save a clod of earth in which the spruce grew in a container. The best time to transplant is early spring.

When digging a hole, you need to take into account the expansion of the tree in breadth so that you do not have to repot the spruce later. During planting, the root collar of the seedling should be positioned flush with the soil surface. With excessive deepening, it can rot, with overestimation, it can dry out. There is no need to trample the ground around the tree, on the contrary - you need to loosen it, but shallowly (5-6 cm is enough). At first, the young spruce is additionally shaded.

Young seedlings of silver spruce.


One-year-old seedlings should be watered 5-7 times a day in small portions. Plants that are several years old need watering 1-2 times a day. Fir-trees, formed into an adult tree, are watered about once a week.

Pour a bucket of water under each adult tree. It is best to do this early in the morning or late in the evening. Water for irrigation should be warm. Young trees are sprinkled every other day - the crown is watered with warm water, due to which dust and dirt are removed.

Top dressing

Thorny spruce does not like natural organic and nitrogen fertilizing. Also, any excess fertilizer can be fatal for her. When introducing it is important to observe the measure and it is better to "underfeed" the plant. Optimal feeding for Christmas trees - special complexes for conifers.

You can start fertilizing immediately after the snow melts in the area. The dry product must be scattered in the near-trunk soil and slightly dug into the ground with a rake. Ate over 5 years old does not need to be fertilized. Many owners of coniferous beauties are inclined to believe that ate grows well without feeding. But if you have already decided to fertilize your tree, do not do it in the fall, otherwise the spruce may not survive the winter.


Despite the symmetrical crown, dry and diseased branches are removed from the plant every spring. If the formation of the crown is necessary, then such a major pruning is carried out in the summer, when the young shoots grow. It is better not to prune in autumn. Places of cuts do not need additional processing with garden varnish, since the spruce gives off a healing resin. It makes sense to form a crown for seedlings under 7 years old.

Removal of diseased and dry branches in the spring.


Adult plants tolerate frost well, and young and undersized Christmas trees need additional insulation. The branches should be pressed against the trunk and secured in this state with a rope. This will prevent them from breaking under the weight of the snow.

The winter sun can damage the needles, causing them to turn yellow and crumble. To prevent this, young trees are covered with cotton cloth or agrofibre during the first winters. Adults did not need to cover for the winter.


Blue spruce most often grows at an altitude of 1800-3000 m above sea level. That is why it is widespread in mountainous and foothill areas, near rivers or streams, that is, in those places where the soil is most humid.

The homeland of the blue spruce is North America, it is there that it grows most often. The brought seeds of the tree made it possible to grow it on the territory of Russia, since it is a picky plant.

Reproduction of blue spruce

For reproduction, seeds or cuttings are used. Only a spruce grown from a cuttings can completely repeat the properties of the mother plant. Common green spruces often grow from seeds, without the bluish tint of the needles.

Growing spruce from seeds

The buds are harvested in the winter in February and then kept in a warm place until they open. Seeds are taken from them, buried in wet sand and stored in the refrigerator until spring. In April, the seeds are treated with a weak solution of potassium permanganate and planted in the soil.

The soil for planting seeds should consist of peat and garden soil. When planting, seeds are buried 1-1.5 cm. The container is covered with a film or transparent container, and the soil is constantly moistened for 3 weeks. When the seedlings grow a little, they are thinned out.

Young Christmas trees are planted in open ground a year later, after setting a positive temperature outside. First, pits are dug for them at a distance of 25 cm from each other, drainage is laid on the bottom. The second time, the trees are planted in the third year of life.


In mid-spring, a branch 7-10 cm long should be broken off from the top of an adult spruce, with a piece of bark at the base. It must be cleaned of needles at the bottom and soaked in a weak solution of potassium permanganate. You can root directly in the garden, but better in a container.

First, the hole is covered with a layer of drainage, the cutting is placed there. Then add soil taken from under an adult spruce, and then sand. The planted cutting is watered abundantly.Cover the top of the sprout with a transparent bag, a plastic bottle. It is moistened about 4 times a day before rooting. For the winter, a young rooted seedling is sheltered when grown outdoors.
