There is nothing more beautiful than a well-kept garden planted with flowers and bushes. Especially in the springtime, when everything starts to bloom, it is impossible to pass by without admiring. Particularly noteworthy are the gray spirea bushes Grefshem.

Spirea Gray "Grefsheim": Description

Spirea "Grefshaym" - this is one of the grades of gray spirea and is its hybrid. Gray Spirea "Grefshaym" has such characteristics: the bush can reach a height of 1.5 - 2 meters. It has the shape of a ball with smoothly curving reddish branches. The leaves of this ornamental shrub are pointed, about 3 cm long, and 1 cm wide.

Spirea begins its flowering in May and blooms for more than a month. The flower in gray spirea "Grefshaym" white, about 1 cm in diameter. Flowers grow in inflorescences, in the form of umbrellas and are evenly distributed throughout the branch, resembling a garland.

Conditions for growing spirea "Grefshaym"

Spirey "Grefsheym" refers to unpretentious plants. But nevertheless, you need to know some of the important conditions that the Grefsheim spiraea requires for planting and maintenance in the open field.

The choice of lighting

Before you grow a spirea, you need to choose a suitable place for it. First of all you need to pay attention to the lighting. Spirea loves light, so a place for growing and further care should be chosen well lit. In the penumbra, the ornamental shrub can slow down in growth.

Soil for planting

Spirea "Grefshaym" does not require specific care, but for its planting it is necessary to pay attention to the choice of soil in which it will grow. Spirea "Grefshaym" takes root in any land, as long as it is not over dried.

Selection of seedlings and soil preparation

A good seedling should not have leaves. When buying seedlings of gray spirea bush Grefsheim, you need to pay attention to the roots. If the root system is open, then there should not be blackness and cuts on it. Roots must be flexible and wet. If the seedling is sold in a pot, then you need to pay attention to whether the roots have not sprouted through the drainage holes. If yes, then the plant is old and it will be bad to take root.

If the acquired seedlings have an open root system, then they should be prepared this way:

  1. Roots that are damaged or too long are trimmed with shears. Attention should be paid to the place of the cut - it should not be stratified.
  2. The shoots of the seedlings are cut to one third of the entire length.
If the purchased seedlings have closed roots, then they need to be poured with water in large quantities. If the ground around the roots is too petrified and simple watering does not help, then the seedling should be dipped in a bucket of water for two to three hours. The pit for planting a spiraea "Grefshaym" should be of such depth as the height of the root system of the seedling. And the width is two times larger than the diameter of the root system. If the soil is clay, can not do without drainage. It can be made from sand and pieces of bricks. To prepare the nutrient soil is taken sod land, peat, sand and mixed in equal parts. In the pre-prepared and ventilated pit pour the sand-peat mixture.

Seedling planting scheme

Before planting a seedling in a pit, you must:

  • fluff and unravel the roots
  • clean the roots from the dry ground, keeping the main room in which the seedling was located.
After the procedure, we lower the sapling into the pit, fill it with earth and tread lightly. We water very plentifully and mulch with peat around.

The gray spirea will dissolve its flowers for the first time in the third - fourth year after planting.

Watering and soil care

Spiraea does not require frequent watering. It is necessary to water a decorative bush twice a month, pouring one and a half buckets of water under it. If there is a drought, you need to water more often. The soil where the ornamental shrub grows must be well permeable. The land around the plant needs to be loosened and weed free. It is advisable to cover the roots of Spirea for the winter by sprinkling a thick layer of foliage on them.

Spirea pruning

Particular attention should be paid to pruning shrubs. Pruning spirea is best done in July, after flowering. Young branches that have bloomed, pruned to strong buds. Spirea buds are formed all over the stalk, so every year pruning is not worth it. It is only necessary to remove frozen, crooked, dry branches. Every spring, the spirea bush is pruned, if it is more than four years old. Spiraea is cut and leaves are 30 cm tall. If new shoots develop poorly after pruning, the bush should be divided and transplanted.

Reproduction of gray grease spirea

If you want to breed spirea for sale or for planting in your garden, you need to know how to propagate it. In the gray spirea Grefsheim reproduction can occur by grafting. To do this, select woody branches. They are cut, remove the top and part of the leaves. The stalk is planted in a damp, loose earth. To seedlings were strong, when planting you need to adhere to the distance between them about 20 cm. In order for the seedlings to grow healthy, you need to keep them in a warm place with good humidity in the greenhouse. If there is no greenhouse, you can simply observe that the land where the sapling grows does not dry out. Cuttings will grow quickly if they are watered frequently. It is possible to transplant the cuttings into the open ground as soon as they take root. You can do this in spring and autumn.

You can also propagate the spirea by dividing the rhizome. This should be done in the fall. The bush is dug out, shake off the sticky ground. Split so that each bush has two shoots and strong lobe of roots. When landing in the soil it is necessary to make a drainage.

Major Diseases and Pests

The main pests of the spiraea "Grefsheym" include spider mite, aphid. If you notice a spider web, a hole in the leaves, and the bush looks unhealthy, the spirea has become a victim of the spider mite. It is necessary to spray the shrub with "Karbofos" solution.

If half of the green leaves of the spirea are curled and its inflorescences are affected, then aphid has settled on the shrub. She sucks the juice from the inflorescences. In order to overcome the aphids, the bush should be sprayed with a solution of "Pyrimora." Spiraea gray rarely exposed to diseases and pests. It is necessary to carry out prevention in time, treating the shrub with chemicals to prevent trouble.

Gray Spirayu "Grefshaym" often used for decoration in landscape design. Florists appreciate this shrub, as it does not require much care. Ornamental shrub becomes a great decoration on any site.

Spirea: Varieties and Description

In the world there are 90 varieties of spirea, and they differ not only in shape and color, but also in terms of flowering.

Most of the varieties have curved hanging branches, although there are also direct-growing bushes. The separation is made at the time of flowering.

Spring varieties bloom on last year's shoots, so pruning is done immediately after flowering. Although the blooming of spring varieties of spirea is abundant, it is short and the flowers are exceptionally white.

Spireas, blooming in summer, delight not only a variety of colors - from pink to crimson, but also the duration of flowering. These varieties are pruned in the spring, as they bloom on young shoots.

Spring varieties include:

  1. Spiraea arguta (Argut) is distinguished by long serrated leaves up to 4 cm long. White umbrella-like inflorescences densely cover a two-meter shrub.
  2. Spiraea vanhouttei (Vangutta) grows up to two meters in diameter and has long arched branches.
  3. Spiraea cinerea (gray). Gray Spirea Grefshaym (photo below) - the most frequent guest in the backyard. Its white fragrant flowers cover the bush with a solid carpet, giving it the appearance of a large white ball.

Summer varieties are most often represented by varieties:

  1. S. Japonica (Japanese spirea). It is an erect shrub up to 1.5 meters in height with large leaves up to 10 cm in length. It blooms for a month and a half, it has many species that differ from each other in coloring.
  2. S. betulifolia (birchwood). Unique in that its foliage, very similar in shape to birch, acquires a bright yellow and purple appearance in the fall. Inflorescences of corymbose form of pink or white color.
  3. S. x billardii (Billard spirea) is often planted as a hedge, as it is easy to care for and cut. It has large pyramidal inflorescences of pink color.

A separate species is considered spirea with spike-shaped inflorescences (Douglas, Lemoine, Ivolist and others). They bloom in mid-summer, rarely reaching September.

Gray Spirea Grefshaym: the choice of landing site

This amazing plant always attracts attention. During flowering, it looks like a snowball, and during the rest period its grayish in summer and bright yellow leaves in autumn, densely covering its curving branches, resemble a ball.

For decorating the site it is important that the plant got accustomed and grow quickly. Is no exception and gray Grefshaym spirea. Planting shrubs begins with the choice of location. It should be well lit, as even a penumbra slows its growth. Many gardeners plant spiraeus along the fences on the sunny side of the site.

Also important is the quality of the soil in the selected area. Gray Spirea Grefshaym well acclimatized on any land (alkaline, neutral, acidic soils), if it is not overdried. The best time for planting is autumn, when the foliage has already been dropped, although it can be produced in the spring, before the buds appear.

Gray spirea planting pattern

Since the Spirea gray Grefshaym grows quite powerful, then when creating a hedge it is recommended to keep the distance to half a meter between the bushes. Between the rows it is 40 cm.

If you plant plants in groups when decorating the site, then the distance should be 50-70 cm, sometimes up to one meter. The width of the landing pit for spirea should be 30 percent larger than the size of the root system. Depth ranges from 40 to 50 cm with regard to drainage.

This ratio of the distance between the bushes and the volume of the holes allows the spirea to quickly grow.

Spiraea Sulfur Care

Gray Spirea Grefshaym, whose care does not require close attention, is very attractive to gardeners.

For this variety, moderate watering is recommended with loosening the soil and weeding. Mulching can be made to a young seedling, for which it is enough to sprinkle the ground with a layer of peat. Since the spirea gray Grefshaym is used for the formation of hedges and the delay of dust and cold air, we can safely say that it is a frost-resistant plant.

The only thing that this variety of spirea badly reacts to is the temperature drop. In an unstable climate, it is advisable to cover the roots of a shrub for the winter, for which it is enough to put a thick layer of leaves on them. One of the most important factors in the care of spirea is its pruning.

Reproduction of gray spirea Grefshaym

In order to grow a beautiful blooming gray spirea Grefsheim on the site, it is better to reproduce it by grafting.

Young shoots are absolutely not suitable for this, even if they give a violent color. For reproduction, it is necessary to select only woody branches, in which the tip and part of the leaves are removed immediately after cutting.

The tip of the branch needs to be cut diagonally, and then plant the cutting in a loose moist soil. For growing strong and healthy seedlings, cuttings should be planted at a distance of up to 20 cm from each other and kept in a warm room with high humidity. If there is no greenhouse or greenhouse, then it is important to ensure that the earth does not dry out. Frequent watering cuttings - the key to their rapid growth.

In open ground, the roots of the cuttings can be transplanted both in spring and autumn. Spiraea shrubs are rarely sick, but prevention from pests and diseases will not be superfluous.

Diseases and pests gray Grefshaym spirea

Although spirea is considered to be a strong shrub, it has pests, although few. To avoid trouble, it is advisable to carry out maintenance work.

  1. Spider mite affects not only this type of shrubs. The main signs of sabotage are the appearance of cobwebs on the shoots, the leaves that have not turned yellow by the time, and the foliage has fallen, holes in the leaves and inflorescences and an unhealthy type of shrub. Easy to get rid of by spraying 0.3% karbofos.
  2. Aphid primarily damages inflorescences and young foliage, as it bites off and sucks the juice. Spraying with a 0.1% pyrimor solution, which is also detrimental to other types of pests, is suitable for killing aphids.
  3. Listoverka rozany able to destroy from 20% to 60% of the leaves of the shrub. The caterpillar twists them and gnaws.

If you spray chemicals with spirea before the beginning of the vegetative period, then it does not face any danger, since this plant is extremely rare.

Spirea gray in the landscape

Landscape gardens are becoming increasingly popular, and shrubs such as spirea, are in constant demand. They are used to create a hedge, and for alpine slides, and for group compositions.

For the formation of beautiful groups the best partners for the spiraea will be the broom, viburnum, many-flowered suckers and honyniki. On their background and in their surroundings, spirea looks even more elegant and whiter.

Application in garden design

Excellent annual flowering and a spectacular pattern of openwork crown of white drooping garlands make Spirea Grefshaym indispensable for giving freshness to any corner of the site. Planting an unpretentious plant is possible on different types of soil and in gardens with any light. Gray spirea will grow even in full shade as a ground cover, but without abundant flowering. Endurance and frost resistance provide easy maintenance. The bush develops rapidly and blooms in the second year. At one place the shrub grows to 30 years.

  • From the bushes of Spirea Grefshaym make out a low hedge, which looks amazing during flowering and does not allow a lot of roadside dust into the yard.
  • The plant is effective in single planting and in small groups of 3-5 bushes.
  • On large squares, Spirea Grefsheim is planted in romantic alleys.
  • Bushes give the form of a sphere, a cube, a rectangle, a cascade.

Short-cropped shrubs are combined with low-growing herbaceous plants: multi-colored yarrow, hunter, lavender, silverweed. The hybrid creates picturesque ensembles with other spring-flowering spireas: medium, nippon, argut. As partners for the ornamental shrub are viburnum, goof, collar, euonymus, broom, juniper, thuja and coniferous trees.

Growing up

The spiraea is transplanted by Grefshaym in the fall, dividing the bushes or moving the cuttings and rooted cuttings. Planting in the spring requires the purchase of seedlings with a closed root system. Transplanted plants also in early spring, before budding.

For successful flowering, even such an unpretentious plant as spirea, requires the fulfillment of a number of conditions.

  • If the spiraeus is planted with a decorative purpose, choose a well-lit place. In the penumbra bloom will be less lush.
  • Spirea Grefshaym takes root on acidic and slightly alkaline soils, but still prefers slightly acidic.
  • When planning a long placement of a bush of gray spirea in one place, one must take into account that its roots are spreading.
  • The shrub will be weakened on dry soils.

The strong plant will turn out from fresh sapling.

  • The stems and roots are elastic, without damage.
  • Open roots are thick, flexible and moist, without black spots.
  • Good seedlings with open roots - without leaves.
  • If the seedling is bought in containers, the roots should not protrude from the container - such spirea seedlings are overgrown and do not take root well.

Grefshaym digs a hole for the gray spirea to a depth slightly greater than the length of the roots, the volume is twice the root bundle.

  1. Plants in containers are poured with water or immersed in a large container with water along with a pot so as not to injure the roots before planting.
  2. Long roots are pruned.
  3. On heavy soils, drainage material is laid on the bottom of the hole, adding sand.
  4. Planting substrate is prepared from equal parts of garden soil, sand and peat, adding standard complex fertilizers.
  5. Planting a seedling, shoots are cut, leaving two thirds of the height of the trunk.

After watering the spirea seedling, the soil needs to be mulched with peat or old sawdust.

Spirayu Grefshaym watered every two weeks - 15-20 liters under a bush. In dry periods, you need to water once a week, and if the spirea blooms, then 2 times. The soil is cleaned of weeds and regularly loosened, preventing the formation of a dry crust after watering.

Be sure to care for ornamental shrubs include sanitary pruning, periodically removing dried, twisted or damaged branches.

  • Forming pruning spirea Grefsheym carried out after flowering, in July, giving the planned shape of the bush. Only the tops are cut, to large buds, if they want to get a flowering shrub the following year.
  • Anti-aging pruning is carried out in early spring for bushes over 4 years old, leaving shoots 30 cm high.
  • With a weak development of pruned shoots, the spirea bush Grefsheim in the autumn is divided and transplanted.

In the spring, after pruning and in the phase of bud formation, the ornamental shrub is fertilized with minerals, such as Kemiroy. In the fall, the soil around the bush is loosened, spilling potassium-phosphorus preparations. At the same time, alternative fertilizing with organic matter can be carried out.

With the onset of cold weather, the soil around the bush of the spirea mulch with peat, the leaves are laid on top. Крону связывают и укрепляют, чтобы ветки не обломились под снегом.

Spirea Grefshaym is not susceptible to fungal diseases, but a spider mite or aphid can live on the bushes. Modern acaricides are used against ticks. Aphids are destroyed with the help of the insecticide "Pirimor".

Having planted a long-flowering shrub, you can enjoy its beauty by arranging a cozy corner for relaxation nearby. Spirea Grefshaym - a great choice!

General information on sulfur spirea

Spirea gray grefsheim fast-growing shrub that different simplicity in care and has a magnificent decoration. In ancient times, spirea and its many varieties were used to make wickerwork and whips. Subsequently, this plant was used exclusively in landscape design, allowing you to equip living fences and decorating homestead territory.

A variety of sulfur spirea was bred in Norway in 1949 by hybridizing the St. John's Wort and White-gray spirea. In its description, the shrub is distinguished by a strong branching, its shoots are felted and ribbed. The foliage is greenish-gray, the lower part is much lighter than the front side. Flowering begins in May and lasts for several weeks. Flowers of white and milky color, arranged in loose shells. The height of the bushes, depending on the age of the plants can reach 90-200 centimeters. The first flowers on the shrub appear in May, and in June the first ornamental fruits are already formed.

Spirea Gray - description

Spiraea gray - branched shrub up to 2 m high with felt-pubescent branched shoots and leaves with pointed on both sides, the upper side of which is gray-green, and the lower side is somewhat lighter. Spiraea gray blooms with white flowers, gathered in corymbose inflorescences, located along the entire length of the shoot. At the very top of the inflorescence sessile, but the lower they are located along the branch, the longer the leafy twigs become, on which the shields form. Flowering gray spirea begins in May, and at the end of June the fruits ripen.

When planting gray spiraea.

Experienced gardeners claim that the best time for planting gray spirea is autumn, when trees shed their leaves around mid-September. You can plant spirea in the spring, but you need to have time to plant before the buds begin to open.

Choose a sunny plot for a plant in a place where it will be clearly visible: the plant will need a lot of light, and in the shadow of a spiraea will develop poorly, and flowering will be scarce. In extreme cases, you can put white spirea in partial shade.

The soil needs fertile and well-hydrated plants. If you are going to grow spirea in clay soil, you will have to lay a 15-20 cm thick drainage layer made of broken bricks or crushed stone into the pit, mixing them with sand.

How to plant a gray spirea.

Landing is carried out on a cloudy or even rainy day. When planting a spiraea for a hedge, keep a distance of about 50 cm between bushes and at least 40 cm between rows. In a group planting plant maintains a distance of 50 to 100 cm. The size of the planting pit at a depth of 40-50 cm must exceed the root system volume Sapling 25-30%. Pit before planting should stand at least 2 days.

Saplings with an open root system should be put for a few hours in a bucket of water, then rotted, damaged or dry roots should be removed and shortened too long. The shoots of the seedlings are shortened by a third. Fill the pit with a mixture of top, fertile soil with peat and turf ground. The root neck of the seedling should remain level. After planting, the soil in the wheel circle is compacted and watered abundantly at the rate of 1.5-2 buckets of water per seedling, and when the water is absorbed, the surface is mulched with a layer of peat not less than 5 cm thick.

How to grow gray spiraea.

Caring for Spirea Sulfur is simple: you need to water the plant so that the soil around it is always slightly damp. In a drought, it is necessary to moisten the tree trunk circle twice a week, and in rainy weather watering may not be necessary at all. After watering, loosen the soil in a circle and remove the weeds.

Spring dressing is applied after trimming the plant: a mullein solution is poured into the tree trunk circle, in which superphosphate is added at the rate of 8 g of granules to each bush. For a more lush flowering, the spiraeus is fed with Kemiro wagon at the rate of 90 g of fertilizer per 1 m².

Pests and diseases of spirea sulfur.

Sometimes gray spirea suffers from snails. To protect the spiraea bush gray from gastropods, process it in early spring and immediately after flowering with Fitoverma solution. From time to time, spiraea is plagued by rosacetes, aphids or spider mites. From aphids, the plant is treated with Actellic, Bitoxibacillin, Etafos or Pyrimor, from spider mites - Phosphamide, Karbofos or Fosalon, and from leafworms - Actelltic, Avant, Ditox or other drugs from leafing pests.

Due to improper care, spirea can be affected by ascochytosis, septoria, or Ramularia. They destroy the infection by treating the hive with copper-containing drugs: Bordeaux liquid or Fundazole solution, for example. Copes well with fungi and colloidal sulfur. Spraying spraying fungicides carried out before flowering or after it.

Spirea gray after flowering.

Gray spirea shows winter hardiness even in the most severe winters. Problems can arise only when temperature fluctuations occur during the winter, and the frost abruptly gives way to thaws. In such winters it is better to cover the root zone of the spirea. The underground part of young plants also needs to be protected from frost, the stem of which in the autumn should be mulched with a thick layer of dry foliage or peat.

Types and varieties of spirea sulfur

Today, only two varieties of sulfur spiraea are grown in culture:

  • spirea gray grefshaym - a spectacular and durable, constantly flowering plant with a height of 1.5 to 2 m with a wide-round spreading crown and red-brown branches. The bush is covered with numerous small white, pink or red flowers. The leaves of this garden form are green or yellow-orange, with a bronze tint. Planting the gray spirea Grefshaym and caring for it is no different than growing plants of the main species,
  • gray spirea Graciosa - a flowering shrub 1.5-2 m tall with sprawling wide-round crown, arcuate hanging branches, narrow lanceolate green leaves, acquiring yellow color in autumn, and snow-white flowers gathered in umbellate inflorescences. The flowering of this spirea also differs in abundance and duration.

Spirea gray in landscape design

Gardeners and designers are very fond of this hybrid spirea for simplicity, winter hardiness, shade tolerance, early and long flowering. Gray spiraeus is used for single and group plantings, for complex compositions, as well as for creating a hedge. The classic design style involves the placement of gray spirea in reservoirs. Rural style lovers appreciate the spirea for compactness and sophistication: it perfectly harmonizes with the tones of Provence style and, like no other bush, corresponds to the Scandinavian style.

It is difficult to find a plant with which it would be impossible to combine spiraeus. Using it as a semantic center of the composition, the gray spirea is surrounded by low-flowering plants at the same time - roses, peonies, alpine asters and Turkish carnations. You can plant a bush spirea, which looks like a sprinkled with snow in bloom, next to red, burgundy and pink tulips, daffodils, crocuses, alyssums and primulas. This shrub combines not only with flowers and ornamental plants, but also with fruit trees, as well as with other flowering shrubs.

Spirea Grefshaym - origin of the variety

The genus Spiraeus is quite extensive, some of which are easily amenable to inter-species crosses. In the course of one of the experiments, two types of spirays were subjected to crossing: the animal-white and whitish-gray, the “fruit of love” of which was the magnificent gray spirea — a beauty that is resistant to urban smog and dust.

This new hybrid was created in 1949 and has since been enriched with many varieties, the most famous of which Grefshaym is rightly considered.

Decorative qualities of Spirea Grefshaym

"May snow", "bride", "white boiling" - the people have picked up a lot of beautiful synonyms for the name of this variety. If we recall that the name of the type of spiraeus (speira) comes from the Latin "bend", then Grefsheim fully justifies its name. Its branches, drooping down to the ground, are arched, sprinkled with white flowers, giving the plant the shape of a fantastic and fragrant waterfall.

The pronounced decorativeness of the Grefsheim variety is due to:

  • responsiveness to pruning,
  • white terry flowers thickly covering each shoot
  • yellow mid-flowers and charming long stamens, causing the desire to consider them.

Like all white flowering spireas, Grefsheim belongs to spring flowering. Blooming flowers, it pleases at the end of May and remains blooming for about a month, without losing freshness and flavor.

Attention! From the second flowering, Grefsheim begins to attract bees. This must be remembered if there are small children in the family.

Breeding hybrid spiraeus

This shrub is easily reproduced by seed, but the signs of offspring in hybrids are unpredictable. Therefore, with respect to Grefsheyma, reproduction is practiced in a vegetative way.

  1. Spireyu bred cuttings in the middle of summer. The developed semi-woody branches of the current year are selected and cut into 10-12 cm long segments. The lower section of the cuttings are powdered with a root tree and planted under the film in fertile soil (either perlite or vermiculite). Provide constant soil moisture.
  2. Layering can be done in the spring, during the blooming of the kidneys. Healthy peripheral branches are bent to the ground, laid in the grooves, pinned and sprinkled with earth. The tips of the shoots are tied to the stakes so that they maintain a vertical position. Do not allow the soil to dry under layings. In the fall, the branches are separated from the parent plant, dissected into individual seedlings and planted in prepared pits.

How to care for the spiraea Grefshaym

Even the most unassuming plant will certainly respond to competent care. The main operation for the care of spirea is pruning. Since Grefshaym blooms in spring, this work is done in summer, when the plant enters fruiting season.

Pruning allows the shrub to return a presentable appearance and contributes to more lush flowering next year. Unlike fruit trees, spirea can be trimmed with a normal shears, without worrying about the specific location of the cut. Fresh shoots are shortened by a quarter, old, thickening crown, as well as dry and frozen slightly cut out.

If the rejuvenation of the shrub is planned, in early spring all its crown is cut under the stump, which gives an incentive to activate the sleeping buds. Out of all the shoots, 5–6 markedly strong shoots are left, cutting out the rest low. In July, they are shortened by a quarter, and from next year pruning is carried out as usual.

Among other measures for the care of Grefshaym spiraea appear:

  • top dressing with high-grade mineral fertilizer after pruning and in early spring,
  • weed control by weeding, some gardeners practice mulching, but in full beauty, spiraea, especially trimmed in the shape of a ball, manifests itself against a black ground,
  • watering as needed
  • shelter for the winter when winter temperatures are 25-30 degrees below zero.

Council The name of the main pest of Spirea is somewhat unexpected - it is a snail. In the case of the spread of such an affliction, treat the bushes with phytosporin.

How to determine the place for Spirea Grefshaym in the garden

Spirea gray calmly refers to the amount of light, so it can be placed in the bright sun and in shading, for example, in front of the north wall.

Like other types of sprayer, it is most often used for the formation of flowering hedges along the paths, along the perimeter of the property or around the house. The line of bushes, torn by an arch with white climbing roses, will serve as a ceremonial entrance to the recreational zone of the site. The fence allows you to aesthetically mask garden plots or economic part, for example, tanks with irrigation water.

Spirey Grefshaym looks great in solitary landings: near the porch, in the middle of the lawn, at the turn of the path or at the edge of the barbecue area. If you do not give the bush to grow, its branches, as if poured with whipped cream, will move along the rock arias, emphasizing the primitiveness of the stone with their tenderness. Cut branches are suitable in bouquets of roses instead of hybrids that are annoyed.

If you are going to update the garden with a hedge or a single spirea bush, stop the choice on the Grefsheim variety. This unpretentious plant does not take away precious time from the gardener, but it will give a whole month of flowering openwork wilted branches.

Using gray spirea in landscape design

Landscaping specialists and owners of private houses appreciate this shrub for its frost resistance, unpretentiousness, long and early flowering. There are several popular ideas for locating this shrub in the backyard area. Excellent composition is obtained by arranging gray spirea around tulips, daffodils, crocuses and other flowers. You can also plant various types of shrubs along the chain-link mesh and fence, and in a few years we will get an attractive, tender hedge.

Spiraea Grefsham ashy shrubs differ in terms of their floweringtherefore, many gardeners and design specialists planted in the immediate vicinity various varieties of this plant, which makes it possible to obtain an original composition in which flowering shrubs are combined with spirea, on which small ornamental fruits are already ripening.

Planting gray spirea

The best time to plant spirea saplings is sulfur autumn months, and to perform this work is best to complete the leaf fall. In the event that the planting is carried out in the spring, then such work should be carried out before the start of leaf opening on fruit trees and shrubs. It is noticed that the seedlings that are planted in rainy and cloudy weather take root best. It is best to plant spireas in a well-lit place, which is protected from the wind.

The depth and diameter of the pit under the spirea seedlings should be selected depending on the size of its root system.
