If you want to improve your site with vegetation, pay attention to a wonderful shrub called Argut spirea. Among the many similar forms of plants in your garden, she will stand out with special elegance and beauty, of course, if you provide her with full care for harmonious growth and development. What you need to know about the rules of growing handsome, and how to organize care for her - read on.
This article focuses on unpretentious winter-hardy deciduous shrub belonging to the family of pink. Argut spirea is a hybrid form, the “parents” of which are Thunberg spirea and a multi-flowered variety. It can reach a height of two meters in height, and is often spread three meters wide. Four-centimeter leaves of spirea - dark green, narrow, lanceolate and strongly serrated. Branches - thin and curved in the form of an arc. The shrub is distinguished by its special decorative value due to its white flowers, reaching up to 0.8 cm in diameter. All of them are collected in umbrella inflorescences, which densely cover the entire bush. Flowering occurs from May to June, with flowers placed on last year's shoots. Did you know?Spiraea was the first source of aspirin known to all. As early as 1839, the glycoside salicin was discovered in its shoots, which, as a result of chemical transformations, has become a well-known drug. Spiraea argutta refers to slow-growing plants, with an annual increase of only 10-20 cm, but it tolerates pruning well.
Distribution and habitat
Given that the described shrub belongs to the hybrid forms of plants, it can be found rather near private estates and in parks, rather than in open areas. It is well acclimatized on fertile soils and is distinguished by a high level of frost resistance, due to which it can be grown in almost all regions (except the northernmost).
Familiarize yourself with the peculiarities of growing Japanese spirea, white spirea, Nippon spirea, Bumald spirea, willow spirea, Grefsham spirea, birch spirea, Wangutta spirea.
Use in landscape design
The botanical data of the Spirea Argut allow it to be used in landscape design, both in single and in group plantings. The plant is suitable for landscaping private, urban and even industrial sites, looks good in hedges, parks, gardens and mixed plantings, favorably standing out from the rest of the plants with its delicate white flowers.
Conditions of detention
The first thing you should pay attention to before planting a bush is the place of its future growth. For argut spirea, an open solar area would be an ideal option, without close occurrence of groundwater. However, if you do not have a way out and you are forced to plant this beauty in the shade, then it will take root there, except that the flowering will not be so lush. As for the composition of the soil, it is better that it be fertile, but clayey soils and loams will also not become a big problem. To facilitate the adaptation process, a mixture of sod land, peat and sand can be poured into the landing pit, keeping the ratio 2: 1: 1.
Soil and fertilizer
As we have already mentioned, Argut spiraea feels great on fertile soils, but this does not mean that you have to constantly feed it. In most cases, planting fertilizer will be enough for a plant for a year, or even more, and additional nutrients will be needed unless after cardinal pruning. Did you know?Spirea from antiquity is widespread in Russian land, so it is not surprising that during the times of the existence of Russia, people found practical application for it. Of the long and thin rods often made ramrod and carrot. In the latter case, the plant removes all the shoots, and the bush begins to grow again (from the root), for which he will need strength. You can prepare the nutritional composition by mixing organic matter (compost 5–7 cm thick) and complex mineral fertilizers in the amount of 30 g of urea and 100 g of Kemira.
Watering and moisture
The plant needs systematic, but moderate watering, especially when it comes to mulching soil. In hot and dry summer days, the application of liquid should be done once every three days, and in normal weather, with moderate precipitation - once every 7-8 days. Usually, about 15 liters of water per bush should be used in one irrigation, after which the soil is mulched so that it does not become covered with a crust.
Plant reproduction and planting
Being a hybrid plant, Argut spirea is unable to reproduce by the seed method, but it is very well suited for grafting and cultivation by layering. 10-centimeter cuttings are cut from the semi-lignified shoots of the current year and are placed for 12 hours in a solution of humic fertilizer or a parstimulating composition. After the specified time, they are placed in prepared pits, deepening 3-4 cm into the soil.
Also layering can propagate lilac, ivy, hydrangea and dracaena.
If you perform this procedure in the middle of summer, then by the fall there will be good roots. If possible, you can use green cuttings that are cut at the beginning of summer. The length of such segments should be 7-10 cm, and it is good if there are distant lower leaves on them. In this case, the planting depth will correspond to 2 cm. So that they grow up, they are tied to pegs, thereby directing in the right direction, after which they are watered and fertilized once every 7 days with organic matter. With the right care for the next spring there is every chance of getting decent seedlings, with a well-developed root system. Important!For faster development of rhizomes, the first inflorescences that appear on young bushes, it is better to immediately remove. The most suitable time for planting Argut spirea seedlings is the first half of April. The pit should be prepared in advance by digging a small trench, 0.5 m deep and 30% larger than an earthen seedling. To begin with, a drainage layer prepared from a mixture of pebbles, rubble and expanded clay (approximate thickness - 10 cm) is placed on the bottom, and a 5-centimeter layer of sand is placed on top of it.
The landing process itself is as follows:
- Taking the seedling at the base with one hand, lower it into the pit so that the root neck is flush with the soil surface.
- With your second hand, gently fill the pit with a mixture of soil and fertilizer, carefully making sure that all the roots are well straightened and not directed upwards.
- Having filled up the rhizome, pour the seedling and sprinkle some more earth, and after 30 minutes pour the soil with liquid humic fertilizer.
- It is useful to soil the soil surface with a peat layer 5-7 cm thick.
At this landing can be considered complete, and all that is required of you in the future - to ensure the plant proper care, in compliance with watering and pruning.
Argut spirea blooms in spring and practically does not need pruning. The only exception would be the sanitary measures that take place immediately after the flowering of the shrub. To be removed dried, damaged branches and old shoots that are more than five years old. Bleached shoots should not be shortened, as this will only increase the growth of side branches and there will be no effect of the falling “hair”. Spirea pruning. Argut spirea is formed at the end of March or at the beginning of April by removing frozen and weak branches. Only 5-6 strongest shoots are left. In order to fully rejuvenate the bush, you will have to remove all the old branches at the root, so that dormant buds awaken and go to growth. Important!In order for Argut's spirea to retain its decorative properties, it needs a lightening haircut (pruning of long-flowering shoots), which is performed every 2-3 years.
Possible difficulties in growing
With a responsible approach to the issue of growing plants, there should be no difficulties. However, there are several nuances that are still worth remembering:
- The argut spirea planted in the fall may simply not survive the winter, even despite its high winter hardiness. Young plants are not as strong as fully formed, so it is desirable to provide them with the most comfortable conditions for growth and development,
- Pruning shrubs deserves special attention, because if you cut off the flowering shoots, this will lead to increased growth of the side branches, with small flowers at the end (the overall decorative appearance of the shrub will suffer). Otherwise, this type of spirea is unlikely to cause you trouble.
Pests, diseases and prevention
Argut spiraeus is deservedly considered a hardy plant, because the habitual shrub ills are almost not afraid of it. For the most part, it suffers from pests, among which are spider mites, aphids, rosaceous leafworm, rosaceous miner and various caterpillars:
- The spider mite gnaws holes on the leaves and inflorescences and leaves the spider webs on the shoots. The leaves turn yellow, dry and fall prematurely, and insects are especially active in hot and dry summers. To get rid of pests and return the plant all its decorativeness, it is necessary to treat the spiraea shoots with a 0.2% solution of Phosphamide, Acrex, Keltan or Karbofos.
- Aphids mainly affect the leaves and young inflorescences, while organizing in whole colonies of harmful insects. She drinks all the juice from spirea, starting its activity from the end of June and continuing to rage until August. For the treatment of the affected plant, at the beginning of the growing season, apply a granular composition of 5% "Pirimor", which is applied to the soil, deepening by 2-5 cm (15 g of substance per square meter of territory).
- Rosan leafworm is activated at an average temperature of +13 ° C. The pest caterpillars pull a few leaves into a tube and gnaw holes through them, causing the bush to dry and lose its decorative effect. For the treatment of the plant, use a 0.7% mixture of Bitoxibacillin mixed with 0.03% Pirimor.
Familiarize yourself with methods of dealing with spider mites and leafworms. These insecticides can be applied when other pests appear, therefore they will never be superfluous. If you want to protect argut spirea from any such danger, then it is better to plant seedlings away from a possible source of infection and to fertilize plants in a timely manner. As for diseases, spirea can suffer from such infectious ailments as gray mold and various types of spotting, but this is extremely rare. The drug "Fitosporin". For the treatment of these misfortunes, fungicidal preparations like Fundazole, Fitosporin, Bordeaux mixture and colloidal sulfur are used. Provide proper care and attention to spirea argut - and the shrub will always delight you with its beauty and elegance, becoming an excellent element of landscape design.
Spirea varieties, varieties and hybrids
Spiraea (lat. Spiraea) includes up to 100 species, each of which has its own name. Rarely, but you can hear or read another name, - tavolga, the origins of which are drawn from ancient Russia. Spirea varieties are very diverse in shape, color and even the shape of the leaves. The shrub is a perennial plant, so every year you can observe how the spirea grows and becomes more lush.
Spirea is unpretentious in the care, sometimes due to weather conditions due to lack of light and heat grows with fewer flowers, but always remains beautiful. There are spring flowering and summer flowering spirea. In spring, flowers, mostly white, are formed on the shoots of the second year; in May, the bush becomes covered with beautiful buds:
oak spiraea is a weeping-shaped shrub, can grow up to two meters and blooms before other varieties, after May 10-15. Shrub fully covered with flowers
Argut's spirea (sharply serrated) begins to bloom in the last days of May. The shrub has narrow leaves, drooping branches, grows up to 1.5-2 m tall,
spirea gray (ashy), often called the bride. Distinguished by its pomp, pubescent leaves of a grayish-green hue, the flowers are small and white. The abundance and pomp of flowers just fascinates.
A rather large number of shrubs belong to spring-flowering plants, among them Nipponskaya spirea stands out. It is a small shrub (up to 1 m), having the form of a ball, blooms closer to June. Another representative of the spirea Vangutta is a strong-growing plant (2.3-2.5 m) with long flexible shoots, gray-green leaves. Flowering begins in the second half of June.
Summer spirea has a mostly pink color of flowers and blooms in June or July, depending on the characteristics of the variety. This group includes the Japanese spirea, which has many subspecies and varieties. The most common and well-known - Nana, Little Princess, Darts Red, Shiroban, others.
Belotsvetkovaya spirea is one of the representatives of the summer-flowering species, characterized by white flowers with a pronounced pleasant aroma, a height of 0.6-0.7 m. Billire's spirea is a hybrid, very cold-resistant. The leaves are wide, the flowers of a delicate pink shade, bloom in July and bloom rather long. Spiraea Bumalda, which belongs to hybrids, is well known. Shrubs have a height of 0.6-1.2 m, depending on the variety planted. Winter hardiness is average, sometimes requires additional shelter (when grown in the northern regions, in the Urals and in Siberia).
Agrotechnika planting spirea
When is it better to plant spirea? Planting spirea can be done in spring and autumn. In the spring they plant only letnetsvetuschuyu, with the condition that the leaves still on the seedlings did not bloom. The roots of the plant should not be dry, carefully inspect the spirea when buying. Shoots must be flexible with good buds. In the case when the roots have been dried, put the spiraea in water with the addition of any stimulator of root formation (Kornesil, Kornevin, Heteroauxin, Zircon, etc.).
What place to put spirea? Choose a sunny lighted plot with fertile soil. Remember, the shrub eventually grows and forms the root growth, so do not plant near high-growing large trees. Juniper, thuja, small spruces will be the best neighbors for spirea.
Proper planting of the spirea suggests the presence of a landing pit that digs a couple of days before planting the shrub. Drainage from pebbles, crushed bricks and other materials is put on the bottom, with a layer of 15-20 cm. For heavy clay lands it is necessary to add soddy, leafy soil (2 parts) and peat crumb (1 part). The depth of the hole rummages according to the size of the root system of the spirea, usually 2.5-3 times more.
The seedling is set vertically, covered with fertile soil, without deepening the root neck, which should be slightly above the ground or level. Planted shrubs better in cloudy gloomy weather or in the evening. Watering spireas after planting is mandatory, pour one or two buckets of water under the bush so that the roots are sufficiently moistened.
In the fall, you can plant spring blooming and summer blooming spirea. It is worth noting that spirea breeding is carried out in the autumn, by dividing the bush. It is necessary to consider the timing of planting spirea in the autumn, which have a fairly wide range, depending on the region of cultivation.
Plants are planted before the beginning of leaf fall, with the condition of full rooting of the plant before the arrival of frost. Usually, in central Russia spirayu is planted in September or October, if the weather permits. In the Urals and Siberia, work must be completed before October.
Proper care - a guarantee of beauty and abundant flowering
In the care of spirea rather undemanding. For good lush flowering and normal growth, the shrub needs plenty of sunshine, fertile land and watering. Shelter spirea for the winter is not always required, only in the northern regions with a harsh cold climate and young plants planted in the fall.
Spirea, planted in the spring, should be well watered, especially in the southern regions, in the Kuban, where spring and summer can be quite hot. In the summer, pay special attention to watering, make sure that the soil in the circle of the tree does not turn into an earth crust, it is important for newly planted spireas.
Pistol space can be peated to create an optimal microclimate and moisture retention. Instead of peat, you can use humus, which retains moisture and will be a good fertilizer that feeds spiraeus.
Spirayu need to fertilize only if necessary, the shrub grows well and without dressings. Обычно, питание дают ранней весной, используя минеральное удобрение с содержанием азота. Осенью вносят только фосфорно-калийные подкормки, чтобы растение набралось сил для зимовки. Азотные удобрения и коровяк нельзя вносить, начиная с августа месяца, чтобы не вызвать рост молодых побегов.
While caring for spirea, many gardeners do pruning not only to give an aesthetic look, but also for the purpose of sanitation, removing loose, dry, broken branches. Although the plant is rarely affected by pests and more, sanitary measures are necessary once a year. Spirea pruning is done in autumn or spring. Adult powerful bushes, it is desirable to cut in the autumn, so that the spring flowering was more abundant. Young saplings, as a rule, are not required to be cut in the winter, it is better to do this in the spring, when it will be seen how the plant overwintered (the frozen off shoots are removed).
Spirea breeding is quite easy; it can be diluted with cuttings, layering or seeds (with the exception of hybrid varieties). We decided to grow spirea from seeds, then take the usual varieties (not hybrids). It will take a container, a box, another container, in which the peat is placed, well moistened. Seeds are sown, covered with foil, planting put in a warm place. When the seedlings grow a little, produce a pick. Planted in open ground, when the threat of frost has passed, mulch and monitor watering. Spirea, grown from seeds, will begin to bloom no earlier than 2-3 years.
Spirea can be propagated by cuttings green or lignified. The cutting is carried out in the month of June. Take a good pruner with a sharp blade and cut off the young shoots at the base (in the root zone). Leaves can be left, and the bark scratched shears, so the formation of roots will begin faster. Cuttings are buried in the ground before the beginning of the place where the leaves grow, must be watered.
Reproduction by layering is carried out in the spring with the appearance of the first leaves. The well-liked young and bending shoots are folded down to the ground, fastened with iron straps and covered with earth and watered regularly. The division of the spirea bush should be carried out with a sharp shovel in early spring, carefully cutting off the necessary part, which must then be transplanted to a new place.
Planting and care for spirea (in brief)
- Landing: in September, in rainy or overcast weather. In the spring you can plant only letnetsvetuschie species.
- Bloom: Species are divided into those that bloom in spring, and those that bloom in summer.
- Lighting: bright sunlight.
- The soil: loose, fertile, consisting of turf or leafy land with the addition of peat and sand.
- Watering: in the dry season - 15 liters of water for each bush 2 times a month.
- Top dressing: twice per season: in early spring after pruning with a solution of complex mineral fertilizers, in the middle of summer with a mullein solution with the addition of superphosphate.
- Trimming: in spring-flowering species in early spring, only the tips frost-bitten over the winter are cut, but after 15 years the plant is cut into a stump for rejuvenation. The shoots of letne-flowering species are pruned every spring to strong buds, and after 4 years, the bush is cut to a height of 30 cm in order to rejuvenate.
- Reproduction: seed and vegetative (by dividing the bush, cuttings and layering).
- Pests: pink miners, rosaceous leafworms, spider mites, aphid.
- Diseases: not sick
Spirea Shrub - description
Plants of the spirea genus are both dwarf (15 cm) and very tall (up to two and a half meters). The root system is shallow, fibrous. The branches are creeping or erect, spread out or lying, from light brown to dark, the bark tends to exfoliate longitudinally. Leaves petiolate, alternate, three-five-lobed, lanceolate or rounded. Spiraeus flowers are small, but numerous, forming a variety of inflorescences - paniculate, spicate, pyramidal, corymbose. The color of the flowers is varied, from boiled white to raspberry. Different species of spirea inflorescences are located differently: in some around the shoot, others - only on the upper part of the shoot, some - only at the ends of the branches. Spirea multiply by dividing the bush, seeds, layering and cuttings.
Spiraea flower is used for group plantings for hedges. Spiry dwarf varieties are great for rockeries, stony gardens and for creating live "carpet". Spirea bush looks great as a single plant.
Spring blooming spirea.
They are distinguished not only by early flowering, but also by the fact that they are characterized by flowers of various shades of exceptionally white color, which bloom on last year's shoots. Flowering begins only in the second year of the escape. These spirays are characterized by strong tillering. In the culture of such species are popular:
Spirea is gray.
It is a hybrid spiraea bee beet and whitish-gray - in fact it is white spirea, and gray is called because of the color of the leaves. Shrub reaches a height of 180 cm, drooping branches, lanceolate gray-green leaves on the underside are gray, scaly-like inflorescences of white flowers are located along the entire length of the branch. It blooms from mid-May to mid-June. The most popular variety:

Very beautiful shrub with felted shoots, while they are young, and naked when they grow old. The height of the bush is 1-1.5 m, the leaves are oblong, ovate, gray-gray below, green above, autumn yellow, red, purple. Japanese spirea blooms to 45 days with red-pink flowers, collected in paniculate-corymbose inflorescences, located at the ends of the shoots. Most popular varieties:

Spirea Cultivation - Features
Each plant has its own requirements for planting and care. Growing spirea also has its own characteristics:
- - prefers spiraea soil sheet or sod. The optimal composition: one part of sand and peat and two parts of the earth,
- - the drainage layer is obligatory, it is possible to use a broken brick,
- - planting spirea is carried out in a pit, which is a third more volume than butt plants,
- - planting depth - at least half a meter, and the root neck of the plant should be at the surface level,
- - It is necessary to plant spirea in cloudy weather, and even better - in the rain. The best time is September.
- - the best neighbors for spirea - juniper, spruce, thuja.
Planting spirea in the spring.
In the spring, spireas are planted only in summer flowering. The main condition for spring planting is to have time before the leaves bloom. If you buy spirea seedlings, carefully consider the roots - they should not be over dried. Check the condition of the shoots from the seedling, and buy only if they are flexible and have good buds on them. Match the planting material: if the seedlings' roots have grown too large, carefully shorten them, and if, on the contrary, the roots are too dry or damaged, cut the branches. If the root system is overdried during storage, spill it with water or soak it briefly in a bucket of water, and only then plant it.
Spirea - unpretentious plant, but for long and abundant flowering, it is necessary to observe certain conditions: the area for spirea must be sunny, the soil should be fertile. In addition, spirea bushes provide abundant basal shoots, which increases the area occupied by the plant, and this must be considered when planning the spirea planting.
So, in the area where the spirea will grow, you need to make a pit with strictly sheer walls, at least one third higher than the volume of the seedling's root system. Then you need to give the pit to stand for 2-4 days. On the day of planting (preferably rainy or cloudy weather), you need to make a drainage layer of 15–20 cm of broken brick, especially if the soil is clay, add 2 parts of leaf or sod land to the pit and mix one part of the peat and sand. mix the mixture, lower the roots of the spirea into the pit, flatten them, throw ground to the root collar and then compact it. Immediately after planting, spiraeus is watered with one or two buckets of water and mulched with peat.
Planting spirea in the fall.
In autumn, both spring flowering spireas and late flowering are planted. Usually, the autumn planting is combined with the spirea planting method of dividing the bush. This should be done before the leaf fall is over. Spireas, which are 3-4 years old, are divided and transplanted; more adult plants can also be planted, but this is already quite difficult to do because of the large earthen coma, which is difficult to extract and launder from the ground.
Spirea bush need to dig, capturing a little more than half of the crown projection. Some roots will have to be cut off for sure, but this will not do much harm to the plant. Then the roots of the extracted bush should be washed well. If the plant is young and not very overgrown, simply put it in a container with water and allow the soil to sift and settle in water, then rinse the roots under running water while straightening them. Cut the bush with shears into two or three parts so that each section has a good root lobe and 2-3 strong shoots. Trim the corded roots.
Dig a hole, put a mound in the middle, place a seedling on a mound and level the roots. Cover the hole with soil and rub it over the surface. In several stages, water the planted delenki with water.
How to care for spiraea.
We have already spoken about the basic requirements of the spirea: bright lighting (although many species grow well in penumbra), loose fertile soil, good drainage and mulching with a seven centimeter layer of peat immediately after planting. What else is needed for spirea to delight you with its beautiful and long flowering?
Since spiraea has a shallow root system, it does not tolerate dry soil and begins to dry out, therefore it needs moderate watering during the dry season: 15 liters of water per bush twice a month. Soil loosening necessarily, like regular weeding. Spirea feeding is carried out by complex mineral fertilizer after trimming a bush, and in the middle of summer it would be good to fertilize spiraeus with a solution of mullein with the addition of superphosphate at the rate of 10 g per 10 l of solution.
Of the pests most are plague spirea aphid and spider mite. The tick is destroyed by karbofos, and the aphid is destroyed by the pyrimor preparation. But for the most part, spireas are not susceptible to diseases, and pests cannot do much harm to their beauty and reduce the decorative qualities of the spirea.
Shrubs tend to grow, so you have to do them haircut from time to time. In early-flowering plants, because flowering occurs along the entire length of the shoot, only the tips that froze over the winter are cut every year, but after 7-14 years all old shoots are removed from the bushes, that is, the plant is cut almost to the stump, then from the most 5-6 strong shoots of young shoots to form a new bush, removing the remaining shoots during the growing season. After a year or two, weak or old shoots are again removed from the bush. At the ends of the shoots pruning should be carried out in the spring, before the leaves bloom, sanitary pruning of old shoots can also be done in the spring, or in the summer.
The blooming spireas are sheared annually in early spring. Shorten the shoot to large buds, weak and small shoots are better to remove altogether. The more pruning, the more powerful shoots grow. It is necessary to remove aging shoots in time, otherwise they begin to shrink by themselves. When the bush is four years old, you can cut the bush to a height of 30 cm from the ground each year, but if after that the spireas give weak growth, you should think about replacing the bush, although on average the late blooming spirea species live for 15-20 years.
Spireas multiply, except for dividing the bush, seeds, grafting and layering. It is possible to propagate by seeds only those spireas that are not hybrids, since the seeds of the spirea still do not retain varietal qualities. But the method of grafting brings very good results - over 70% of the cuttings take root even without the use of growth stimulants. Early flowering spireas are grafted in the first half of June, late blooms - in the second half of June or in July. Lignified cuttings root in the fall, in September and October.
Cut off a straight annual shoot, cut it into pieces, so that each has 5-6 leaves. Remove the lower leaves on each cutting along with the petioles; cut the remaining leaves into half a leaf and place the cuttings for half a day in a solution of epine (1 ml per 2 liters of water). Then, powder the lower node of the cutting with a root stimulator and plant it in a pot in wet sand at an angle of 30-45º. Cover the cuttings with glass or film. Put the container with the cuttings in the shade and spray them with water two or three times a day. When the frosts come, prikopayte cuttings on the garden, cover with leaves, place the inverted box on top and leave until spring. When the next year, the cuttings will give new shoots, they can be planted in a permanent place.
During reproduction by cuttings, the shoot is placed in a groove dug in the ground, pinned and sprinkled with earth. If you want to get a few new shoots, then you need to pinch the tip of the layer, then each lateral bud can give a process. In the fall, the layers are carefully removed and divided into regrown shoots, which are planted.
Spirea after flowering
As has been said more than once, care for spirea is not difficult, including in terms of preparing the plant for a rest period. Almost all species and varieties of spirea tolerate cold, but if the winter is very frosty and, most importantly, snowless, you can take care of the plant by covering the roots of the bush for the winter with a layer of foliage of 10-15 cm. In any case, the will be.
Is it difficult to grow?
This plant is hardy and feels great in almost any climate zone. Bushes for planting in large quantities offer shops for gardeners. It is necessary to acquire the spirea for the site in the spring or in the fall. Depending on the variety, the plant has different heights. Therefore, in advance, ask what size the adult bush will reach, so as not to be mistaken with the choice of the landing site. Спирея отлично подходит для оформления ландшафта, создания границы на участке, в качестве инструмента хеджирования и высадке многолетнего сада.
Подготовка к посадке
По советам и наблюдениям садоводов спирея хорошо развивается на солнечных участках, с рыхлой, плодородной почвой. Ornamental shrubs should be planted taking into account the design of the site. Note that the distance between plants when planting in the form of a hedge can withstand at least 50 cm. With a single arrangement, this distance can be increased. The root system must be prepared before disembarking. If it is open, then damage is well seen on the shoots, which must be removed with a sharp garden shears.
The cut angle should be smooth, clear, not crumpled and wet.
Be sure to adjust the crown of the bush. Regrown branches should be shortened by a third. With very dry roots, shoots are cut a little more. When you purchase a spirea with an earthy clod on the root system, you will need to water it abundantly so that it softens and only after that it can be lowered into the pit for planting.
Under each plant, dig a separate hole or dig a trench. The width is chosen based on the volumes of the root system, usually 50 × 50 cm. It is necessary to dig a hole in advance so that the pit dries out and ventilates. The depth of the pit is 50 cm. They lower the plant into it so that the radical neck is at the level of the soil surface. Prepare the mixture for falling asleep in the pit:
Comply with proportions 1: 2: 1. It is necessary to straighten the roots in the pit and then fall asleep soil mixture. Loosely trample the ground around the bush and mulch with peat. It is preferable to carry out garden work in the fall, in September and early October. Transplanting spirea in the fall will allow the plant to harden before the start of frost.
Rules for the care of spirea shrubs
Planting and care is of particular importance for those who wish to get a beautifully flowering shrub. This is achieved by properly selected and prepared soil. On the scanty land it will not be possible to form a lush and spreading spirea bush.
Clay soils when planting spirea require mandatory laying of drainage from bricks, rubble and sand of at least 15 cm.
Spirea is unpretentious, she bravely endures severe frosts and dry weather. The plant is not subject to attacks of garden pests and diseases. Loosening is not included in the mandatory list and is purely aesthetic in nature.
A spirea seedling planted in autumn should preferably be covered with a special material so that it can more easily endure winter low temperatures.
Spirea, planted in spring, has not sufficiently developed its root system, therefore it needs regular soil moistening. In the summer dry months, abundant watering is needed for flowering varieties of spirea. Wet soil around the shrub will provide favorable conditions and allow spirea to get stronger. Spiraea, which is covered with flowers in spring, does not depend much on regular soil moisture. The exception is those seedlings that have been planted recently.
Additional convenience will give the soil mulching. It will keep the soil moisture under the bush longer. Roots lie close to the surface; in the summer months, 15 liters of water is enough under each bush twice a week.
Fertile soil is already a good basis for growth and development, therefore fertilizer application is not as important as on poor and lean soils. Spirea feeding is carried out in early spring. After pruning, mineral fertilizers are applied (complex). In the middle of summer, mullein and 10 g of superphosphate are used for each plant.
For a beautiful crown and lush flowering, it is necessary to periodically clean the bush from the dead, sick and broken branches at any time of the year. Spiraeus can be severely pruned and this will only benefit her. Pruning spirea in the fall is most preferable. The plant is preparing for the winter season and the extra branches will weaken the bush in spring. When you trim the spirea after winter, pay attention to the tips of the shoots. It is necessary to remove those that froze. This procedure will provide a beautiful bloom.
The shrub that blooms in summer is pruned with the onset of spring. Those that bloom in the spring, subject to this procedure immediately after flowering. On plants older than 10 years, it is necessary to remove all signs of aging so that it forms a new crown. Usually the life of a bush is 20 years.
Some gardeners consider spirea pruning an overkill. In this case, you risk getting neglected thickets with a large number of dry branches and weak flowering.
The plant spiraea is very convenient and unpretentious, reproduction is carried out in several ways: grafting, rejection of shoots and seeds, and the latter option is not suitable for hybrid plants, since the seeds do not appear on them or do not have signs of the mother bush.
Spring is the best time for planting seeds. They are buried in high peat and well moistened. On germination will take 10 days. Further, they are subjected to a picking, when the spirea is transplanted into the open ground, cloudy weather or evening is necessary. Provide mulching and regular watering. For the year spirea is able to grow up to 10 cm in height. The first flowering can be expected at 3 years of plant life.
For reproduction spirea cuttings used stiff shoots or very young - green. For spring blooming spirea, grafting is used in June, and summer plants in July. For the development of the root system, the cuttings are well watered and kept in conditions of high humidity. Spring and the first leaflets - time for breeding tap. The lower branches are bent to the ground, pinned with wire clips and sprinkled with soil. Regular watering will ensure good rooting, and in the spring independent shrubs will be formed. For the winter it is necessary to sprinkle with dry foliage.
Spirea looks great in the picturesque compositions and is rightly popular with gardeners and landscape designers. Lush flowering shrubs attract attention and delight the eye.
