Among the whole group of prickly firs, long favored by gardeners in Europe and America, there are several rather old varieties that have long and firmly settled on the “coniferous Olympus”. They have become almost legendary, this is a classic that does not age. Our current heroine is one of them.
History of creation
It is quite simple when compared with the extensive "track record" of the variety itself. Spruce was obtained by the breeder Ant Kluis Boskouup in 1937, in the Netherlands. He simply selected an unusual specimen from numerous seedlings of standard barbed spruce, and then worked for a long time to retain its features.
The first publication about the novelty falls on 1949, and the mass access to the trading floors was made in 1955, when the perennial tests were completed.
Since then and up to now, Glauka Globoza (Picea pungens "Glauca Globosa") is a favorite of gardeners, the most popular conifer in many countries of the world, a real star of green design. At its base, new cultivars are being created that retain the best qualities of their ancestors.
It looks like a dwarf conifer tree, whose height only in rare cases reaches two meters. In the first years of his life, his crown resembles a slightly flattened ball, often asymmetrical, loose, sometimes one-sided.
And only at the age of about 10 years a clear central conductor emerges from this unintelligible ball, growing more actively and as if carrying the crown. It stretches, acquires a wide pyramidal shape, becomes much denser.
However, it is necessary to clarify that often gardeners and designers deliberately do not give spruce to stretch, and with its constant pruning retain its original sphericity. Only now the ball becomes symmetrical, elegant and very dense.
The needles of our heroine are short, prickly, planted surprisingly tight. Its peculiarity is that each needle is slightly curved, like a tiny serpik. It has a silver-bluish tint, brighter, to almost blue, in young shoots. Due to this, the spring species looks from afar like a bluish living ball, gradually darkening towards the end of summer. The length of annual shoots is usually equal to 6-8 cm.
If cones are formed, their shape is oval-cylindrical, markedly elongated, sometimes up to 10 cm in length.
Features of agrotechnology and use
In general, this spruce tree can be safely attributed to unpretentious conifers. It is frost resistant, able to withstand up to -30 ° without shelter. Easily adapts to the lack of nutrients, as well as to the inconsistency of the soil ideal. Although, of course, it demonstrates its best decorative qualities on fertile lands: slightly acid, sandy and loamy.
Like the whole group of prickly firs, Glauka Globoza is very intolerable to the stagnation of moisture in the soil, as well as to the excessive compaction of the soil near the roots, during planting it requires the organization of quality drainage.
A huge advantage is the high resistance to air pollution, which makes it possible to make wide use of the variety for landscaping city streets and squares.
At the end of winter, especially in early spring, you need to ensure that snow and ice do not accumulate on the concave or flat surface of the spherical crown. They can spoil the needles, even lead to its yellowing and abscission in this place.
Regarding the use in landscape design - this is an indispensable tree, which has not so many competitors, if we are talking about a tiny plot, a small corner of the garden. It looks great on a stone hill, in a small group of plants, and also as a pretty solitary plant that remains beautiful throughout the year.
Many copies in Europe are sold as a tub of plants, capable of making a comfortable and lively balcony, loggia, and a small hallway. If you are a master of trimming, you can gradually form any silhouette of this spruce: it allows you to make real small sculptures from your crown!
As you can see, it is not for nothing that Glauka Globoza is considered a classic! It has many faces, stimulates the owner to work, at the same time is very unpretentious and modest in their requirements. What else is needed to win the love of several generations of gardeners?
Planting and care
Grows better in shaded areas. On fertile soil, spruce forms deeper roots.
When transplanting, avoid overdrying the roots. Afraid of trampling and compaction of the soil. Does not make close groundwater. If the groundwater is close, drainage is necessary, consisting of crushed stone with a layer of 10-20 cm. Root neck at ground level.
Norway spruce prefers loamy and sandy soils.
Turf ground, peat, sand - 2: 1: 1.
Optimum acidity - pH 4 - 5.5
When planting make nitroammofosku (100 g).
Demanding on soil moisture, does not tolerate drought.
It is obligatory to water young plants in a hot dry summer (once a week for 1-1.5 buckets per plant).
Spruce fir makes dry soil longer than common spruce.
Young plants in the dry period require more frequent and abundant watering.
Shallow, 5-7 cm. Under the young plantings.
Peat layer 5-6 cm. Subsequently, peat is not removed, and mixed with the ground.
When using firs in a hedge a radical pruning is possible. Usually, only dry and diseased branches are removed.
Description of Fir species of Glauk
The needles have a light blue color with a bright silvery shade. This tree attracts many precisely with its color. Blue-silver beauty often decorates parks, gardens and lawns, which are located within the city limits. Glauka is popular among landscape design. It can beautify any plot with land and turn it into a fabulous place. With the right placement, this breed will become a real decoration of your garden or summer house.
This tree has several subspecies:
- Blue spruce (the most common),
- Spruce Glauka Globoza (dwarf),
- Spruce Glauka Konika (dwarf).
Grade Glauka Globoza
Picea pungens glauca globosa come from the family of pine. An adult tree can grow to a height of up to 30 meters, in a year a young shoot can grow up to 25-35 cm in height and up to 16 cm in width. The crown of Glauk has the shape of a cone, and its prickly needles are covered with wax, which gives it an emerald color. The plant has a height of not more than one meter. If it is not cut, then it will grow in width more than in length. Dwarf spruce grows very slowly.
Unpretentious care, does not require much attention. It tolerates frosts in northern Russia. In the first years of life, it is necessary to protect the sapling from direct sunlight, so as not to harm the young needles. It is worth remembering that in summer it is necessary to water the plant, like any other.
Grade Glauka Konika, or Canadian Spruce
It is too dwarf fir, but in size it is larger than Glauka Globoza. Konica can grow up to 4 m tall and 2 m wide. Needles are softer than the main species. In a year the young plant increases by 4-5 cm. Konika Glauka loves more shade than the sun. While the sapling is young, the first years should be covered for the winter so that it does not freeze. Sun rays are undesirable for him too. Although it is a miniature spruce, its place is exclusively on the street.
Competent tree planting
Choosing a place for planting spruce, you must build on the factor that it shade-loving plant and grows poorly in direct sunlight. But hitting a small amount of light does not hurt her, only warms the earth a little. When planting, you can use the drainage of the earth and the land of coniferous forests, it will only improve growth and nourish the roots of the necessary trace elements.
Young shoots best transplant in springso they will have time before winter to get stronger. If you transplant a plant in the fall, it may die during severe frosts. The landing pit should be extensive for the root system - about 75 cm. If a group planting is to take place, it is necessary to plant at a distance of at least 3 m from each other. The first time after planting is necessary to water the plant and fertilize.
There are several ways to propagate spruce.
Of course, it is most convenient to buy an already ready sapling and plant it in any place you like. But it happens that there is no opportunity to buy a sapling, and you have to look for an alternative. The easiest way is growing from seeds. Seeds are in conesthat need to be collected in the fall.
Cones must be brought to a warm room and left to dry completely. After you need to carefully get the seeds from the cones and choose the best sowing. Before sowing the seeds, they are soaked in a weak solution of manganese. For best results, they must be stored under snow cover throughout the winter. In the spring, the seeds are dried before planting and planted into the ground to a depth of 2 cm.
As we already wrote, this look is unpretentious in leaving. However, you have to follow the minimum rules in the care of barbed spruce:
- do not overdry land in the summer,
- do not overflow the soil
- hiding young saplings from direct sunlight
- cover young plants for winter
- Replace only in spring.
If you often water the soil, the root system can rot, and it will be hard to save. In the summer, it is necessary to water at least once a week. To improve the growth and appearance of Glauki, you can feed the plant once a year. It is necessary to shelter young saplings from direct sunlight., as the needles are not yet strong and can easily be burned by the sun.
Application in landscape design
In the decoration of the site Glauk fir-tree because of its appearance and characteristic features is one of the first places. Due to the emerald color of the needles, lush crown, frost resistance and ease of care, this beauty can decorate parks, gardens and cottages.
It can also be used as a hedge, which can create a shadow on a hot summer day, serve as a dividing line between areas and just please the eye. Dwarf species of fir Glauk in this sense is no worse - you can create a fence of miniature size. The main thing when seating take into account the dimensions.
If you turn on fantasy and creativity, you can turn a garden or any other site into a fabulous place. Globoza will look gorgeous on the lawns or along the paths in the form of emerald balls. You can also plant the balls in the vases, and the plant will become the center of attention. It is not only convenient, but also practical, lawns in the future can be swapped around the site. Globoza will not always be in the form of a ball, it must be timely cut to maintain shape.
Characteristic varietal characteristics of the plant
This variety of blue spruces was bred quite recently (1937), it differs from its high counterparts by its low growth, which allows it to be used on any, even the smallest pieces of land. Despite the magnitude, the decorative qualities of the fir-tree Glauka Globoz are in no way inferior to their powerful wild-growing relatives. Landscape designers use this tree in their unique compositions, fully applying its properties and qualities:
- Glauka Globoza refers to the dwarf species of fir,
- it grows slowly, for the entire life cycle it gains a height of no more than 1.5 meters (if not pruning),
- does not require a special composition of the soil; it develops well, practically, on all plots of land,
- Young plantings, until they have taken root in a new place, should be protected more carefully: shade and water if they are on the south side of the garden,
- the crown of the spruce has a spherical shape, without pruning it will rise in height, and the lower branches expand in different directions, exceeding in diameter the total height of the spruce.
Attention! When choosing a landing site, consider this feature. The distance from the planted plant to buildings or other trees should be at least 1.5 meters around the circumference.
Variants of using spruce in the design of the site
On the site, each owner individually decides what and how to plant him. Without relying on their imagination or having no experience, some resort to the help of specialists, but not all “afford” such services. Gardeners who decide to take on this business on their own may encounter problems not related to planting, but precisely how beautifully and correctly combine the ornamental Glauka Globoza spruce tree with other plants so that both of them do not suffer from the neighborhood but make up a wonderful ensemble . We will tell and show in the photo how to solve this problem.
First of all, make a clear plan-project of future planting of spruce, given its slow growth, determine what form you want to see the crown of the tree, its height and circumference of the lower branches. Then prepare the pits, fertilize, plant the seedlings in the chosen place. Now you can start forming a tree, it can be in the form:
- low stem with a spherical crown,
- a column with a low trunk and a flat top (like a pillow),
- a high column-trunk with a ball-shaped crown resembling street garden lights,
- peaked pyramid in the image of a fabulous Christmas tree, which is often depicted on New Year's cards.
Neighbors for blue spruce
Planting dwarf spruce oxidizes the soil over time, so you should choose for her neighbors who are not afraid of a slight oxidation of the soil. The low-growing spruce tree Glauka Globoza is well combined with deciduous ornamental shrubs, such as lilac, forsythia, anafalis, bright flowers and the fruits of which stand out beautifully against the background of blue needles.
Rowan berries, gooseberries, sea buckthorn and raspberries are suitable for fruit and berry bushes and trees. In dwarf spruce varieties, the root system does not grow, as in tall trees, neither in breadth nor in depth, which allows, especially in the early period, to plant flowers next to it, annual or seasonal perennials, such as lilies.
Alternating the seedlings of spruce with suitable fruit bushes, you can arrange a colorful hedge that will decorate the site, and you will also get berries. Fill the space between the hedge and the paths with low floral borders, alternating with the bushes of cereal plants.
Features care after planting
We have already said that it is possible to plant Glauka Globaz spruce in any soil, besides, it is unpretentious in caring and tolerates low temperatures well. At the beginning of the growing season, immediately after planting and for the next 2-3 years, you need to follow some rules of care so that the adaptation process goes without problems:
- regularly water the seedlings during hot weather, but do not overwork the roots too hard, this may cause them to rot,
- loosen the ground and remove large weeds,
- when in direct sunlight, make shadow curtains,
- not to prune to form the crown of the tree more than 1 time per year,
- when a disease or insect pests are detected, treat the pesticides in a timely manner.
Decorating their garden or garden, owners do not spare either time or labor. Such costs are paid off by a sense of satisfaction, beauty and pleasure from the sight of magnificent, healthy plants, which they themselves have grown to the surprise and joy of all people.
Characteristic features of the spiny (blue) fir
Blue spruce we call spruce spruce. She is a stranger in our area. This Christmas tree is from the northern state of America - Colorado, from which it got its present name "Colorado". The area of distribution of this beauty in natural conditions is very narrow: the states of Utah and Colorado. You can meet her in the mountains and among the rocks at high altitude.
They called the blue spruce because of the unusual coloring of the needles. All varieties of spiny spruce have a characteristic bluish tint, while the primary color may vary. For example: white, silver-green, silver, blue-green, bright blue (for example, in Hoopsie).
Prickly spruce retains its color all year round. Needles she has the most thorny of all coniferous trees. In length, they can grow up to 4 cm. The needles have a wax coating that helps it to easily endure the adverse urban conditions (polluted air).
The life span of a spiny spruce is very long - up to three hundred years. The height of the tree can be different, depending on the variety. The growth of the tree is very slow.
Fir-tree Glauka, differently “gray-gray”, is known in two versions: standard (ordinary) and small (dwarf). An ordinary tree has a trunk length of up to 35-40 cm and grows by about 1-1.5 m. Dwarf grows more slowly (8-15 cm per year), and its maximum height does not exceed two meters. The correct name of this baby is Glauka Globoza (Sizaya spherical).
Glauka globosa was bred in 1937 by Dutch breeders. This is a slowly growing variety. After 25-30 years after landing, it can reach a height of only one and a half or two meters. Crohn in the initial period of growth has the shape of a ball, slightly flattened. Then gradually acquire a conical appearance.
The branches are tough, strong, grow at right angles to the sides or stretch upward, keep their shape well.
Окраска хвои светло-голубая с серебристым отливом, она похожа по цвету на другую разновидность голубых елей – Хупси. Это хвойное растение отличается особенно ярким оттенком голубого цвета. Хупси – сорт среднего размера, такое растение вырастает до 10-12 м. Beautiful blue spruce is often used to create a forested area within the city.
Globus Globus is very popular among landscape designers. It can serve as decoration for any land plot. In the skillful hands of a specialist, this spruce will give to your garden or cottage an incomparable charm.
The use of dwarf fir for decoration gives a wide scope to the creative imagination. You can plant it surrounded by all sorts of flowers, cereals or shrubs. It will look good fir among the stones. Experimenting interspersed with blue beauty in the overall picture of the natural community of your garden or rock garden can be infinite. This species of spruce lends itself well to cutting the branches, so you can give it any desired shape. You can also make beautiful compositions in your garden with the Hoopsi spruce, its unsurpassed blue hue will be an excellent complement to the dacha landscape.
Coniferous miniature plant Glauka Globoza perfectly tolerates frost and polluted climate of megacities. However, in the first winter after landing, the tree is better to shelter from frost.
How to grow blue globose spruce
El Glauka Globoza likes good care, especially at the initial stage of growth. She really needs light, but the plant can grow in partial shade. It tolerates drought and frost.
The soil is preferred by fertile, sour, well-permeable to moisture and air - for example, loamy or sandstone are well suited. It is impossible to plant spruce on heavy alkaline soil, the tree will feel bad in too dry or very wet soil.
Not suitable for permanent cultivation of a place with a high content of groundwater or wetlands.
Plant spruce better in spring. During this period, the young individual will more easily adapt to new conditions and will get stronger faster. Autumn planting often ends with the death of seedlings, they do not tolerate the winter cold.
Feed spruce once a year with a special compound for coniferous trees.
Propagation of dwarf blue spruce seeds
Spruce can be propagated by cuttings or seeds, as well as grafting. The most convenient way is to plant the purchased ready seedling and transplant it to the chosen permanent location. For cultivation of spruce with their own hands from scratch the best way to seed breeding method. Consider it in more detail.
- The first step is to get the seeds. They are mined from cones that will ripen in the first year of their lives in the autumn. You can collect cones for seed from October until the end of autumn. Collected cones are brought into the heat and left there for a few days, until their scales unfold. Now you can get the seeds from the cones. Seeds are sorted, leaving the best.
- Before sowing, the seeds must be disinfected (treated with manganese solution) and stratified. It is necessary to store them all winter under a snow cover, protecting from rodents.
- Sowing is made with the onset of the first spring days. First, the seeds are taken from a cold place and dried well.
- Planting seeds produced under the film in the greenhouse or greenhouse. For soil take a special composition: peat, fertilizers for coniferous plants and fungicides in a small volume. Place the seeds in the soil to a depth of 2 cm.
- Care after planting seeds: to ensure adequate moisture.
- Grow up saplings up to three years. By this time, future spruces are ready for transplanting into open ground. Do not be alarmed if they will be small. Not all seeds will ascend. This is normal.
- In the open ground, young trees grow another four years, observing regular watering and fertilizing. When the spruces will be about seven years old, they can already be attached to a permanent place, having made the last transplant.
How to breed spruce cuttings
With this method of breeding Spruce Glauk globoza all the characteristic features of the mother variety are preserved. It is more suitable for professionals, but will give a better result than seed reproduction.
For the cultivation of a future spruce, parts of the branches of an adult are taken. They must be chosen correctly: the size of the cutting should be about 10 cm, the cutting itself is cut with a small piece of bark. Cut cuttings produced in the middle of spring or autumn, as well as in summer. To cut the planting material choose young spruce age of eight years. What to do next? Provide good care.
- First, place the cut fragments in a stimulating solution. Then the cuttings are planted with a slope in a special substrate, bought in a store or made by hand: sand plus peat and perlite in the same amount. There should be drainage at the bottom.
- The cuttings are covered with a film, having well moistened the soil, they create a shade.
- When the shoots take root, a year later they are transplanted into a greenhouse. It is important the abundance of sunlight at the initial stage of growth. In greenhouse conditions, seedlings will grow for another four years. Then they will be put on the chosen permanent place.
Seedlings care tips
- Maintain sufficient soil moisture.
- Use dry watering (loosening the soil), but do it carefully: the root system of fir trees is located near the surface.
- Watch what the sapling looks like. If red needles have appeared, it means that the fungus has started, the peeling needles indicate overmoistening.
- When watering, it is desirable to warm the water so that there is no contrast with the warm temperature of the soil.
How to transplant grown seedlings
Seedlings that have reached the age of four years should be transplanted to a permanent place. Transplantation is carried out together with the earth lump.
- Provide a good drainage layer at the bottom of the planting pit if the soil for planting is heavy.
- The volume of the pit is almost twice as large as the earth lump itself.
- The depth should be up to one meter in clay soils (including a drainage layer up to 20 cm), if the soil is sandy, the recess is made up to 80 cm.
- In the recess is placed such a composition of the earth: the chernozem layer and sand in equal parts. Sand can be mixed with sawdust.
- Immerse the earth clod together with the bag or net (so as not to damage the coma integrity), these materials will be decomposed in the earth.
- Gradually fill the spruce with earth, watering and compacting layer after layer.
- Sapling cover with earth to the top of the coma.
Watering after transplanting should be abundant and regular. During the first year in the summer, water is watered twice a week, at other times it suffices once. The higher the plant, the more water must be taken: ten liters per meter, fifteen - one and a half, thirty - two and a half, if the plant is over three meters, they take about forty liters of water.
How to care for spruce after landing on a permanent place
Caring for Glauka Spruce Globe will require you to do the following.
- Process in the first week with a solution that stimulates root growth.
- Spray branches and coniferous cover with “Epinom” dissolved in water: take an ampoule for five liters. You can use "Zircon", diluted it in a ratio of 1 ml per 10 liters of water.
- In the spring hide a fir-tree under a grid with small holes for protection against bright sunshine.
- Help thaw the earthen coma under the spruce after winter, water it with warm water.
- Feed the plant with a fertilizer compound for coniferous trees. The use of urea, manure, humus is unacceptable!
If you do everything right, then lush forest beauties of magical blue color will soon grow in your garden.
The main thing is to survive the first and most difficult stage: planting and growing young seedlings. Patient attitude and good care will do their job. After all, the spruce trees that have grown up and are strong enough grow by themselves, without requiring almost any effort from you in the future.
The root system of the fir-tree Glauka Globoza is close to the soil surface. The branches are short and strong, located at right angles to the trunk.
Needles 4 cm long, with spiny ends, densely growing on the branches. The color of the needles is bluish-silver, they are covered with a wax coating, which contributes to protection against adverse environmental conditions. Needle color does not change with time.
Cones of small size, oblong shape, light brown color, they ripen in the fall, already in the first year of the life of a young tree.
During the year the tree grows by 8-10 cm, its life span is very long, in some sources indicate 500 years.
The use of fir Glauka globoza in landscape design
Exotic silver shade of needles, endurance and undemandingness of Spruce Glauka Globoza make it a favorite of gardeners and professional landscape designers.
It is planted along the paths, as a hedge, as well as in single plantings for decorating lawns. Compact fir will look great compared to other higher coniferous trees.
With the help of trimming this spruce, you can shape the ball, flashlight on the leg or cone. Good looks Globus Globus, planted next to the lilac, forsythia and anafalis.
It turns out a great combination with fruit bushes - rowan, raspberry, gooseberry and sea buckthorn. Flower annuals, such as lilies, will look great next to it.
Often, this miniature Christmas tree is grown in pots, which are located on the balconies and on the roofs.
Site selection and preparation for planting
The place for planting Spruce Globe Globosa can be chosen even in the shade, it does not have to have constant bright light, but the groundwater should not come close to the surface, because the root system of the plant is in the upper soil layer. If this is not possible, then it is necessary to provide a drainage layer with a thickness of 20-30 cm during planting.
Soils for this spruce will fit any, but the best option would be sandy and loamy with low and medium acidity, the main thing is that they should not be limestone and swamped.
Instructions for landing
Planting spruce seedlings on a permanent place can be made from April to the end of July. Saplings of 4 years of age are usually sold. And if they were grown independently from seeds, then they can be transplanted to a stationary place only 7 years after sowing the seeds.
The landing algorithm is as follows:
- Dig a hole 2 times larger in size than the seedling sap. Drainage 20-30 cm thick should be filled to the bottom. The distance between seedlings should be at least 3 m.
- Prepare the soil for planting - mix 2 parts of sod land with one part of peat and one part of river sand.
- Carefully, together with a lump of earth, move the seedling in the center into a hole and cover it with prepared soil, then carefully tamp it.
- Pour the seedling with water with the addition of nitroammofoski.
- Mulch the root circle with peat or sawdust to retain moisture and prevent weed germination.
- In the spring, after planting, it is necessary at first to cover a young tree with a mesh fabric from bright sunlight.
- In the first week, you can pour a solution that stimulates the growth of roots. Spray the branches with Epin or Zircon.
Despite its extraordinary endurance and undemandingness, the spruce tree Glauka globoza needs simple care. It is necessary to make a little effort, and then she will delight the eye with its lush silver needles.
During the dry period, it is necessary to water the spruce 2 times a week for 2 buckets of water per bush. During the rainy season, watering is reduced to a minimum so as not to fill the roots.
It is better to water the trees in the evening with water at room temperature, which has previously been settled for several hours.
A couple of times a year, young spruce is fed with a special compound for conifers. Top dressings are brought in the spring and in the fall. An adult tree will be enough one spring feeding. Do not use urea, manure and humus.
In the first year of her life, spruce cones with seeds are formed on her branches. They can be collected, starting in October. Next, proceed as follows:
- Cones should be placed in a warm dry place and dried, then remove the seeds from the scales, select the best of them.
- Selected seeds must be disinfected in a solution of potassium permanganate and stratified. They are stored in a cool place until spring.
- In the spring, the seeds are well dried and sown under the film or in the greenhouse. The soil consists of peat, fertilizer for conifers and a small dose of fungicide. Seeds are buried by 2 cm.
- After the emergence of seedlings, seedlings are grown in a greenhouse for up to 4 years, then transplanted into open ground and planted for another 3 years, after which 7-year-old trees can be transplanted to a permanent place.
Reproduction by cuttings
Most often practiced grafting. With him, all varietal characteristics are preserved. Produce cuttings in spring, summer or autumn according to the following scheme:
- From a young eight-year-old fir cut cuttings 10 cm long with part of the bark.
- Place the cuttings for several hours in the growth stimulator solution.
- In the container must be laid a layer of drainage material.
- A special soil substrate is poured onto the drainage layer, acquired in a store or composed independently of equal parts of peat, perlite and sand.
- Planted cuttings at an angle, and well moisten the soil.
- Cover the planted cuttings with film, and transfer the containers to the shade.
- A year later, rooted cuttings are moved to the greenhouse, and there they grow for four years, after which they can be planted in open ground at a permanent place.
- During the period of growing the seedlings in the greenhouse, it is necessary to water them in time with water at room temperature, loosen around the ground and weed.
After the winter, sanitary pruning is performed, during which the twigs are broken and damaged by snow. To achieve the desired shape, spruce is also pruned, but not more than once a year, as the tree grows very slowly.
Mulching and loosening
After each watering, the soil around the fir should be gently loosened, trying not to damage the roots that are close to the ground.
Mulch the soil around a tree trunk with peat or compost. It is necessary to timely remove weeds that provoke diseases and attract harmful insects.
Fight against diseases and pests
Galuka Spruce Globoza may be susceptible to fungal diseases, their symptoms are manifested in yellowing and browning of the needles at the end of the summer period. This leads to the complete dropping of the needles. Another disease is characterized by wilting of the upper shoots and the complete drying of the tree. You can cope with these ailments with the help of systemic fungicides.
Spruce can attack and insects - pests, such as:
- Spider mite Its appearance can be seen on the thinnest cobweb and yellow spots on the needles. In this case, it is necessary to apply acaricidal complex preparations.
- Aphid. It usually affects the lower branches of a tree, and it can be difficult to notice. To combat aphids apply soapy water, and cut the diseased branches.
- Stem pests. These are small bugs that gnaw through holes in the bark and can destroy the entire tree if they are not noticed in time. To combat them use the appropriate insecticides.
Preparing for the winter period
Adult Spruce Glauka Globoza has a high frost resistance and easily tolerates frost -35 degrees. But young trees in the first two seasons for the winter are best covered in the usual way:
- To mulch the land of the trunk circle with peat or sawdust.
- Neatly tie shoots ate with ropes.
- Wrap them with a special covering material, tie them with ropes on top so that the wind could not tear the shelter.
- In the spring, gradually dismantle the shelter, but make sure that the first sun rays do not burn the needles. The first time to cover young trees with a mesh cloth from the bright sun.
Winter care for mature spruces consists in timely shaking off snow from the branches.
