What is the difference between spruce and white spruce? The most important difference is the bright spring shoots of cream color. For several weeks, the needles on the shoots acquire a silver-blue, beautiful shade, but in the spring the tree does not look quite familiar. As a result, the spruce looks different at different times of the year, which is what decorates the garden.
Spruce white-sided spruce grows very slowly, for 10 years it grows up to only two meters in height and up to 1 meter in circumference. Over time, it reaches five meters in height, and three meters in diameter.
The crown can be in the form of a cone, in the form of a wide cone, or asymmetric.
The needles are dense, prickly, rigid, needles up to 3 cm in length.
The cones are male and female, brown and red respectively. They are dense and oblong, 5-10 cm in size.
Planting and care
Barbed spruce bialobok grows well in the shade, but still looks better in bright light. Young plants and seedlings need pritenyat spring and summer from sunlight to prevent burns.
Spruce prefers acidic sandy or loamy soil with good drainage and slightly acidic or acidic reaction. In the summer it needs watering, but it does not tolerate stagnation. Drainage in the pit must be made of broken clay brick, coarse sand or gravel.
It tolerates frost well, suitable for planting in the 4th climatic zone. Its branches are strong, do not break and do not bend under the weight of snow.
Looks good in a single or group planting in the garden, park, front door and at official buildings. For group planting, the distance between the trees should be within 3-5 meters. They should be planted so that with age they do not shade each other, and do not interfere with each other.
A small, slowly growing spruce can be grown for several years in a decorative container, and then transplanted into the open ground with the ground.
Depending on the age and size of the seedling, the pit for planting should be 50 to 70 cm deep. The neck cannot be buried, otherwise the tree may die. When planting in a hole poured a bucket of water, put a seedling, sprinkled with earth, watered again. The following watering can be carried out in 15-20 days.
White-sided spruce can be planted in winter, but this will require a special substrate. Watering is not carried out.
Fertilize spruce immediately after planting, using root and nitroammofosku. Then feeding is carried out twice a year with special fertilizers for conifers.
In the hot season, the spruce is watered once a week, the amount of water depends on the age and size of the plant, most often, from 1 to 20 liters of water per tree. After watering, it is necessary to loosen to a depth of five centimeters.
In autumn, in preparation for wintering, the ground around the trunk is sprinkled with peat, a layer of 5-6 cm. In spring, peat is not removed, but mixed with the ground, leaving as fertilizer.
They do not cut spruce; it grows nicely and evenly without that, but if it is necessary to make a hedge or give a decorative shape, the tree tolerates trimming well. It is best to do it in May-June, after the completion of the period of active movement of juice.
Spruce white-sided has no typical diseases, the main thing is to properly care for it, and then it will only remain to admire its unusual beauty.
Bialoboc spruce is propagated by seed or cuttings. For this, the cones are harvested at the end of autumn and put into a warm room so that they open up there and release seeds. Seeds are treated in a solution of potassium permanganate, put in a container with heated sand and put in a cold place for stratification. If there is no other suitable place, you can put it in the fridge.
Well-prepared seeds give good seedlings. However, as is often the case, not all plants will inherit parental traits. Most of them will grow ordinary firs without bright shoots. To preserve the signs, it is better to propagate the spruce by cuttings, cutting them from a plant older than 10 years.
Cuttings do not root very well, roots do not allow more than half of them, but you can be sure that as a result real white-side spruce will grow, with albino shoots.
For reproduction, it is better to choose erect cuttings so that the herringbone grows straight and level. Cut them off at the trunk, with a piece of wood. On wood make cuts, from which the roots should grow.
The cuttings are planted in containers with the substrate and put in a shaded place. The roots will appear faster if the soil is heated from below or the horse manure is poured to the bottom of the tank. It will burn and give off the heat necessary for rooting the cuttings.
Christmas tree prickly Belobok (picea pungens bialobok) differs from others in its light shoots during growth. That spring, the tree becomes so unusual. Later, in a few weeks, light shoots turn silver or blue, and then green. Thanks to this feature, the tree looks at different times in a completely different way, which makes it a real decoration of any area.
It grows very slowly and in ten years it grows only up to two and a half meters in height. The maximum this spruce can grow five meters in height. A small tree acquires an irregular shape, and later it will grow cone-shaped or asymmetric.
Needles are hard, up to three centimeters in length. Cones oblong to ten centimeters in length. There are female and male. Women - red, men - brown.
Planting and growing
Ornamental plant completely unpretentious and does not require special care. It grows well both in the shade and in the sunny area, but in bright sunlight it looks much more beautiful.
Young, not yet grown up trees, it is better to shade from direct sunlight to prevent sunburn. The soil on which it is supposed to grow the plant should be acidic and well hydrated.
In the summer, it is imperative to regularly and abundantly water the spruce, but make sure that the water does not stagnate. To do this, when planting, it is imperative to pour rubble or stones for drainage into the pit.
This spruce tolerates frost and heavy snow. It has strong enough branches and it can withstand a large amount of snow. Looks great in one copy, and in the landing group. Decorates the park and large flower beds and home gardens.
When planted in groups, the distance from one tree to another must be at least five meters in order for the spruce to grow the correct shape. A small Christmas tree can be planted in a large pot and grown for several years in such a state, and when the tree has grown stronger it can be transplanted into open ground.
The pit for planting is dug up to seventy centimeters deep. The root collar is not necessary to fall asleep, since this can lead to the death of the plant. In the pit you need to pour drainage, soil and water well. Then put a tree in a hole and sprinkle with earth. Top also need to pour water. The next time you need to water only fifteen days.
This spruce can be planted in the winter season, but this requires a special substrate and watering is not carried out in any case.
You can immediately fertilize the herringbone after planting nitroammofoskoy.
Basic rules of care
- Water spruce need to once a week. On one young tree about five buckets of water should go away, as the spruce ate grow, the volume of water should be increased. In the summer, watering should be increased.
- After watering, when the top layer of soil dries out, it is necessary to loosen the ground around the tree so that no earth crusts form.
- In autumn, the tree should be sprinkled with peat to make the tree easier to winter.
- In the spring peat is mixed with the ground, thereby fertilizing the soil.
- Pruning is not necessary, spruce itself forms the correct form, but if the spruce is used as a hedge, pruning is best done in early summer.
- This fir is sufficiently resistant to disease. If you properly care for her, she will not require special care. This variety is very rarely ill.
- In the spring, spruce need to be treated with fertilizer.
Cultivation: basic requirements
- Illumination. Light-requiring, shade-tolerant, but not shade-loving. The best place is with full exposure to the sun. With partial shading, the needles lose their color saturation. Young plants pritenyat - in the spring sun burns are possible.
- Priming. Fertile, permeable, well drained, without stagnation of water - from black soil, sandy loam to loam. The pH reaction is acidic, slightly acid. Negative attitude to soil compaction, stagnation of water.
- Watering. He likes moderately wet ground. In the heat of eating under the age of 2 years, watered weekly - about 10 liters per tree. As the root grows, reaching deep layers of the soil, the need for irrigation of spruce decreases.
- Reproduction is carried out by cuttings, rarely seeds. With the latter, the parental traits of the variety may not be preserved. When propagating by cuttings, the survival rate is slightly above 50%. Reproduction is possible by grafting on tall species, which is practiced by many nurseries.
- Frost resistance. High winter hardiness, recommended climate zone 4.
When planning the garden, they calculate the distance from the neighboring crops. Low dwarf tree with age reaches the diameter of the 3rd. The new dimensions of the tall tree will break the garden composition, and the plants will suffer in reducing the area of nutrition, in shading.
Tip! The asymmetrical shape of the crown of a young spruce and its certain curvature are corrected by a garter to the supports, setting the direction of growth.
Exploring the biography
Even looking at the Latin name of the variety (Picea pungens Bialobok), it becomes clear that it would be more correct to call it “Bylobok”. The Polish gardener Jan Bjalobok from Lublin, who discovered an unusually mutated spruce in the 30s of the last century, would undoubtedly agree with this. Jan did not pass by, but preserved and propagated a tree, which seemed to him promising for later use in a green design. Further work on the development and retention of the unusual varietal properties of spruce was carried out in the arboretum under Cornicus.
Thanks to what qualities did Mr. Bialobok decide to keep a copy? The fact is that he had unusual young shoots: creamy yellow, almost straw. They retain this color for 5-6 weeks, and at this time the Belobok spruce looks like a beauty with which few people can compete in the “spruce kingdom”. The spring combination of cream, yellow, bluish shades of needles creates an unsurpassed effect!
Interesting! In Russian-language literature, it is often possible to find a judgment that the name of a variety is associated precisely with such “white sides” of spruce. As we already know, this is not true.
There is another false opinion about this species. It is often called dwarf variety. Indeed, in the first decade it develops slowly, growing by only 1.5 - 2 meters during this time. But unlike these dwarfs, this spruce tree continues to grow further. At the age of 30-40 years it can reach a height of several meters. Agree, dwarfism is not what you call it! We are dealing with a medium-spruce spruce, the diameter of which can reach three meters in solid age.
The crown of a tree is usually cone-shaped, but it is asymmetrical, with a wide, as if flattened cone. Shoots are short, thick, grow almost horizontally. The needles are hard, prickly, about 3 cm long, gradually acquiring a bluish-gray tint. Not every year, but cones appear on the branches: brownish males and almost red females. With age, they darken, turn brown, like all other firs.
Spruce Belobok - strong, unpretentious plant. He loves sunshine, it is in such areas that the spring growth is especially bright. But can grow in partial shade, losing some of its charm.
Copes with air pollution in urban environments. Prefers slightly acidic, well-drained soil, negatively reacts to an excess of organic matter and mineral fertilizers.
It tolerates pruning and sometimes needs it, especially if the crown begins to lose symmetry. Absolutely does not tolerate soil salinization, stagnation of water near the roots, excessive compaction of the earth, therefore the tree trunk should be periodically loosened and mulched.
Winter hardiness is high, in the middle lane it does not need a shelter. It is not highly susceptible to common diseases and pests, especially with proper care.
Use in landscape design
Due to its long branching ability, Belobok looks good in open areas and garden meadows. Suitable for planting in parks, gardens, perfectly combined with other plants in garden compositions. In the first decade of life, it is also used as a container plant, which is easy to carry from place to place.
From these fir trees you can get a beautiful hedge, they will decorate rockery, the backyard of the plot, picturesquely combined with a green lawn, especially in spring.
How to grow white spruce
In order for the development of spruce to be correct and the growth constant, it is necessary to ensure that moisture at the roots does not stagnate. Therefore, a layer of drainage is made under the tree; broken bricks and sand are good for it. 15-20 cm thick drainage layer is optimal.
When planting fir trees in groups between trees, make a distance of 2-3 meters. The depth of the pit for the root system is 50-70 cm.
Planting spruce, you need to make sure that the root collar remains at ground level. Use drainage. It is made with leafy ground, peat, sand, turf ground. They are taken in the ratio of 2: 1: 1: 2. At the first landing, the spruce is watered with 50 liters of water (5 buckets). Sprinkle with fertilizer - 100 g nitroammofoski or 10 g of root.
Belobok does not like heat and drought. In this weather, it is watered 1 time in 7 days, 12 liters of water per tree. So that the soil is loose, and oxygen reaches the roots, the soil under the spruce is sometimes loosened to a depth of 5 cm.
While preparing the spruce for the cold season (winter), peat is sprinkled around the trunk 5-7 cm thick. After winter, peat is mixed with the ground.
Interestingly, this plant, if necessary, planted even in the winter cold. Fertilize spruce necessarily - 2 times / season.
How to care for spruce
The prickly fir-tree loves the sun more, and in the shade its colors fade. Winter hardiness is excellent. Loamy or sandy soil, moist, drained, fits most. Spruce in winter is not afraid of snow, can withstand heavy loads during snowfall.
Spruce Picea pungens Bialobok does not like moisture to stagnate at its roots. Therefore, in the first 1-2 years you need to protect it from "floods", as well as from sunburn. To do this, spruce fir harbor spruce branches or coarse sacking.
Features spruce Belobok
White prickly spruce is an elegant tree, it looks especially beautiful in spring. Her yellow-cream color is elegantly combined with blue needles. Spruce with single planting looks best. She creates an unusual and original interior. Spruce emphasizes the beauty of other groups of plants, focuses on garden and park design.
