Spirea bush is attractive not only during flowering. Her beautifully curved shoots adorn the garden throughout the season.
Planting and growing a spiraea is easy, which attracts gardeners.
Features landing spirea
Like any plant, spirea has its own peculiarities of cultivation. For full bloom they must be considered:
• The shrub prefers soil consisting of deciduous humus and sod land. Part of the sand is added to the two parts of the obtained soil to loosen the soil,
• Spiraea is grown only in well-drained soil, as the shrub does not tolerate stagnant moisture, often suffers root rot or sweeps out in winter,
• The root collar of the shrub is not buried so that it does not rot. Ideally, the root neck should be at ground level,
• Planting shrubs carried out only in cloudy weather, but better in the rain. The optimal landing time is the second half of autumn, somewhere in the middle of September. Some species of spirea are planted in early spring.
Planting spireas in the spring is carried out early, until the buds have blossomed. At this time, only flowering hybrids can be planted. When buying seedlings pay attention to the state of the root system and the appearance of the plant. In well-developed healthy seedlings, the roots must be alive, not over-dried, and the branches flexible with good buds. If the seedlings look suspicious, it is better to refuse to buy. What to do if the planting material was stored for a long time in inappropriate conditions? It must be brought into a "human" form.
Long and overgrown roots shorten, which facilitates planting and increases the survival rate of seedlings. If the root system is too dry or damaged, the shoots should be shortened, and the roots should be soaked in water before planting. For this, the seedling is soaked in a bucket of water for 24 hours.
Planting spirea: the choice of the site and the depth of the landing pit
Spirea is an unpretentious shrub, but it will not fully bloom everywhere. The main condition for growing spirea - full coverage during the day. Choose a sunny area, protected from cold winds. Consider that the shrub grows quickly, gives a lot of basal shoots, so it needs enough space. If you allocate a lot of space is not possible, then the root growth is removed.
Landing pit on the site is prepared in advance. Its depth must be at least 60-70 cm, which is a third larger than the size of the root system. At the bottom of the pit lay the drainage of scrap materials with a layer of 15-20 cm. Part of the bows fall asleep with fertile soil mixed with sand, peat and leaf humus. During planting, seedlings form a mound, plant it, the roots are spread on the sides. Pit to the top filled with fertile soil, slightly compacting the ground, and plenty of water. The root zone is well mulched with peat or humus.
Important! The root collar must be placed at ground level.
Autumn planting spireas spend during the division of the bush. It is best to complete the procedure before the end of the leaf fall. For reproduction using more young bushes, whose age is not more than 5 years. Adult specimens do not tolerate division.
Since the shrub grows quite quickly, you need to consider the distance between the plants. To create a hedge between seedlings leave up to 70 cm. When planting, spirea in compositions with thujas and other junipers around the plant is left up to 1 m, which will greatly facilitate the care of shrubs.
Spiraea Care Secrets
Shrub care is a treat for lazy gardeners, but some features will be useful to know.
Spirea refers to drought-resistant plants, so it is watered extremely rarely. In rainy weather, shrubs can do with natural rainfall. During the dry period, it is enough to pour spiraea abundantly several times a season and mulch the soil.
Around the young seedlings the soil must be regularly loosened. To spirea pleased flowering, it must be fed a full mineral fertilizer. Top dressing is done twice a season: immediately after pruning and in the second half of summer.
How to prune spirea
Shrub needs to be cut, thereby forming a beautiful crown. Conduct a haircut with all the features of the bush.
• In early-flowering varieties, only the tops of shoots that have frozen in winter are cut. Strongly shorten them is not necessary, as the spirea blooms on last year's shoots. After 7-8 years of cultivation, all shoots are pruned at ground level to renew the shrub.
• Summer blooming spireas pruned in early spring to the strongest bud. The more pruning, the more powerful the bush is formed. Every 5 years, the shoots are cut to a height of 25-30 cm. If, after such pruning, the shrub starts a weak growth, then it must be completely replaced. The duration of cultivation in one place is 15 years.
In addition, in the spring and summer, as necessary, they carry out sanitary cleaning of the bush, cutting out all twisted, weak and dry branches.
Photo correct spiraea trimming
While caring for spiraea, we must not forget about the diseases and pests that can annoy the shrub. In most cases, spiraea is resistant to diseases and pests, but is sometimes attacked by aphids and spider mites. To quickly get rid of pests, apply spraying insecticides.
Among the diseases most common is horse rot. Follow the rules of growing shrubs, select a suitable place for planting and be sure to drain the soil.
How to multiply spirea
If you decide to get a spiraea, then it is not necessary to buy seedlings. You can grow planting material yourself, taking a cutting from a neighbor in the country. In addition, spirea is easily and quickly propagated by dividing the bush and layers. Let us dwell on each method.
The division of the bush is carried out in autumn or early spring, depending on the perennial variety. Planting is carried out in the usual way, preparing the soil and planting pit.
Spireyi cutting is carried out throughout the season. Early-flowering species are grafted in the first half of summer, a little later, planting material is cut from late-flowering varieties. The survival rate of the cuttings is very high, even without the use of special preparations, which can only please the gardeners.
For grafting choose one-year direct shoots, which remove the lower leaves. Upper leaves are cut half. The bottom cut of the stalk is treated in the root or simply dipped with crushed ash. Planted cuttings are planted at an angle of 45 degrees in the greenhouse. Care for spirea cuttings is simple, it is enough to water the plants at least 1 time in 3 days. With the onset of frost, the plants are covered with dry foliage, and an old wooden box is additionally installed on top. In this form, the cuttings overwinter. Spring shoots transplanted to a permanent place.
Photos of ready spirea cuttings for planting
It is easy to reproduce the spiraea by layering. In the fall, a semi-woody shoot is added dropwise, and in spring the seedling is transferred to a permanent place. By that time, he should have formed his own root system.
Important! Spiraeus seeds are propagated extremely rarely, as this is a rather complicated method. In addition, plants rarely retain parental qualities.
As you can see, spirea is a perennial flowering shrub for busy gardeners. Planting does not take much time, and care for the plant is simple.
However, despite the winter hardiness of the shrub, with the arrival of autumn it is better to fall asleep with dry leaves. This will save the perennial from freezing in snowless winters.
Features of cultivation and types of spirea
Spirea bushes, which are short - 15 cm, and large - up to 2 m, are very popular. The plant is unpretentious, well adapted to heat and frost, it is easy to care for it, and there are so many varieties that you can create compositions that bloom from spring to late autumn.
Plants of this species are light-requiring, hardy and undemanding to the ground. Spireas are very good for urban conditions, as they tolerate atmospheric pollution. Bushes grow very quickly, begin to bloom in the third year.
The nuances in the cultivation of spirea are related to which species a particular bush belongs to - early or late flowering. This factor affects the time and duration of flowering, and also determines the characteristics of planting and cutting. Bushes blooming in spring come together in May, becoming covered with white buds. In summer varieties, the inflorescences are predominantly pink-magenta.
Not many ornamental shrubs can live like a spirea, up to forty years in not the most favorable conditions.
Planting spirea is better in the fall, after leaf fall. Some varieties tolerate spring planting well, but they need to be carried out before the leaves start to bloom. When planting, it is important to choose the right place: the site should be sunny with rich non-uniform soil.
When planting a hedge, between the bushes need to leave gaps of about half a meter. In the group, spireas are planted at a distance of 50-70 cm. For each plant, dig a depression, a third larger than the root system (about 50x50 cm). The depth of the pit is 50 cm. Do not plant bushes on the same day; let the landing site air out for three or four days.
Sowing seedlings before planting, keep them in water for several hours, remove damaged roots. Determine where the root neck is, at its level should be the top layer of the earth.
Before planting, place the mixture in the recess:
- Sodland - 2 parts.
- Peat - 1 part.
- Sand or broken brick - 1 part.
Spread the roots, fill the pit with soil and a little trash. Pour two buckets of water and grind the soil with peat.
Attention! The clay soil needs to be fluffed up by adding drainage from rubble and sand. The height of the layer is about 20 cm.
Features of spiraea care
Spirea is able to be beautiful, without requiring increased attention to his person. Provide it with fertile, loose soil, sufficient light, good drainage - and it will bloom for many years. During the season you need to feed it only three times. Only young bushes need winter warming. The main difficulty in the care of the bushes - competent pruning.
When landscape planting, spirea is surprisingly multifunctional, which is explained by the variety of varieties. Low bushes fit organically into rockeries. A group of bushes of different varieties look spectacular against the background of lawns and next to pines, juniper, spruces and other conifers.
When watering spirea need to comply with the measure. The plant loves moisture, but water stagnation is destructive for it. Make sure that the ground under the shrub was moistened, but note that under the spreading branches the moisture is stored for a long time. Grind the soil and in the heat, water each bush with one or two buckets of water every 10 days.
Top dressing and fertilizer
In order for a bush to be rich in color in early spring, it is advisable to feed it with Kemira Universal (100 g per square meter). Top dressing will increase immunity, spirea will not hurt. Also well perceived complex mineral fertilizer.
In July, feed spirea with a mixture of mullein (bird droppings) and superphosphate. It is easy to prepare the composition: 10 l of a diluted mullein and 10 g of superphosphate. If your spirea grows on fertile soil, you can not feed it. You can start feeding in the second year.
Spring-blooming spireas pruning is needed only to remove old shoots and dry branches. Pruned branches immediately after flowering.
Pruning flowering bushes can be the beginning of spring, starting in the fourth year. Haircut should be cardinal, as late species Spireas quickly lose their shape. Old shoots will be laid on the ground under their own weight. If you cut only the tops, new shoots will be thinned, and small inflorescences.
Council If you are afraid of cutting the plant shortly, experiment: cut only half of the bush and compare the results in the middle of summer.
To activate flowering in the summer, shoots can be cut, removing a third of the length. When this side shoots are formed. When the branched branches sprout, remove the thin processes below the branch point. As a result of such pruning, the branching will increase, the access of light and air to the whole plant will improve.
The flowering of early varieties occurs on the shoots of the past year. In single bushes pruned weakened branches, leaving strong and healthy. Spirea grows very quickly, so you can safely remove a fifth of the shoots in the fall, cutting them off at ground level. Spring shoots will grow with a new force.
Remove twisted and weakened branches should be after flowering or early autumn, leaving a strong growth. Once every two or three years, spireas are carefully thinned, cutting the branches inside the bush. Radical thinning is carried out every seven to ten years, leaving only a few of the most viable branches.
In the first years, while the root system is being formed, it is impossible to cut off the spirea strongly. Pruning and thinning of adult plants should be carried out regularly. In the fall, new shoots are pruned to the level of the buds above the woody part of the branch, and form the shape of a bush. After such a haircut in spring shoots will fork and form a dense bush. Council Be sure to cut off the inner space of the bush - this measure prevents the formation of mold, the penetration of pathogenic bacteria and the multiplication of pests.
Prior to the onset of the first frost, stimulating pruning is performed. A plant that has reached 3-4 years of age, at a height of about 30 cm, removes all lignified branches. Such pruning will allow recovery before spring, and new side shoots will bloom safely by mid-summer.
Older bushes of 15–20 years old and pests damaged by plants can be rejuvenated by spending deep pruning in the fall. The bush is cut to the ground level, and in the spring it will begin to develop anew from the buds of the root collar. Do not leave stumps on which sprigs from lateral buds will start growing in the spring - they will be weak and will worsen the decorativeness of the bush.
Hedges are also better to cut in the fall. Firstly, because the plants will be prepared for wintering, secondly, you will save spring time, when gardeners have enough worries. The best time for autumn pruning is September-October.
Autumn transplant perfectly tolerate all varieties of spirea. Moving to a new place can be undertaken in the autumn when the leaves begin to change color. For transplant, choose a cloudy day. Remove dried parts, trim the skeletal branches to the bud on lignified escape. Undeleted old branches will dry up, so cut them without a doubt.
Reproduction by seeds.
For some varieties (Van-Gutta, Billard, Boumald et al.), Seed multiplication is not used, because the seedlings are heterogeneous. In early spring, seeds are placed in containers with soil. When the sprouts get stronger, they are moved to the garden by pinching to the main root. This is done so that a strong root system can develop. Seedlings will begin to bloom in three to four years, and before that care must be careful. Often water young plants, loosen the soil and perform weeding.
Reproduction by layering
This simple and reliable breeding method is good when you need to get only a few new bushes. When leaves begin to bloom in spring, bend a branch to the ground, pin it with wire and sprinkle it with earth. You can tie the branches to the peg in an upright position. During the season moderately moisturize the soil, and by the fall or next spring you will receive a new plant. The development process can be accelerated by removing the first inflorescences on young bushes.
Universal love for Spirea is due to its long and abundant flowering. Numerous small flowers are collected in pyramidal, paniculate, spike-like or corymbose inflorescences. The early varieties are white, summer bloom with flowers of pink, lilac or crimson.
The showiness of the bushes is explained by the duration and different timing of flowering, as well as the way the inflorescences are located on the branches. In some species, the inflorescences completely cover the shoots, in others only the upper parts bloom, in the third, the ends of the branches bloom. Spring varieties of spirea bloom wildly, but not for long, and the flowering of summer species continues until mid-autumn.
After hibernation under the fallen leaves, females of the tick migrate to the young leaves, weave around the bush with cobwebs and lay eggs. Spider mite multiplies so actively that the whole spirea becomes covered with whitish spots, turns yellow and loses leaves. The spider mite is especially dangerous in the dry summer.
Defeating the pests is possible with the help of agrotechnical, biological and chemical measures. The main weapon is spraying the bushes in the dry summer, watering and feeding.
To combat aphids suitable granular pyrimor. At the beginning of the growing season (April), a 5% solution (15 g per square meter) is introduced into the soil to a small depth (2-5 cm).
Aphids, rosaceous miner and leaflet do not like the effects of drugs:
- pyrimor - 0.1%,
- Actellic - 0.1%,
- hostakvik - 0.1%,
- kronefos - 0.3%,
- fosalon - 0.1-0.2%,
- etafos - 0.2%.
Council For greater efficiency, it is recommended to combine biological products with pesticides. Чтобы извести тлю и листовертку смешайте 0,7-процентный битоксибациллин и 0,03-процентный пиримор.
Паутинный клещ пропадет после обработки фосфамидом, кельтаном, фозалоном, метафосом, карбофосом или акрексом. With the timely start of treatment, when no more than three ticks settle on a sheet, the result comes quickly.
Common varieties of spirea
Reaches 1.2-1.5 m in height. Upper leaves are lighter than lower ones. Complicated inflorescences of rich pink color continue to bloom all summer.
It blooms in May-June with inflorescences-shield from white to light gray. It grows up to two meters and looks very attractive due to the generous flowering and elegant branches.
A variety of gray spirea differs in frost resistance and long spring flowering. It blooms so thickly that “Grefsheym” got the name “May snow”.
Polutorametrovy shrub grows to a meter in diameter. It blooms in summer. Panicles inflorescences reach 15 centimeters in length. White spirea is moisture-loving and requires regular watering.
This variety is also called red spirea. Shrubs up to 70 cm in diameter. Young leaves and branches are bright red, spirea inflorescences are pink to bright crimson.
This species survives well on the shores of reservoirs. The leaves of the willow leaf spirea are elongated, and pink panicles of inflorescences delight from May to July.
Small shrub grows to 80 cm. It has a spherical shape and a bright pink bloom.
Spirea Golden Princess
Small bushes no higher than half a meter resemble golden knolls with pink flowers. It continues to bloom from mid-summer to late autumn, keeping the color of leaves.
Spring spirea, very spectacular, with thin arcuate branches and abundant flowering. Two-meter bush with a very sprawling crown.
The name of this variety must elliptical shape of the leaves. Low shrub spherical shape. By autumn, the leaves become bright yellow.
Late flowering variety reaches a height of 1.5 meters. Flowering lasts 45 days.
Low early flowering variety no higher than one and a half meters. The shrub is decorative due to the graceful leaves, which acquire an orange color in autumn, and abundant snow-white bloom in spring and early summer.
Why do spirea shoots dry?
The dried branch must be cut in any case. See if it is damaged by a pest. If you find traces of the disease, cut off all dried up shoots, cover the places of cuts with green paint or garden pitch. It is possible that the root system of spirea was damaged by moles. Another option is to root the roots. Rumble the ground around the bush with a rake and spray the bushes with zircon.
Scrub care in winter
Most species are hardy and feel great even north of mid-latitude. They are not afraid of harsh winters. Spirea is gray, dubrovolistnaya, low and medium. Kidneys in these species are damaged only at 50 degrees of frost. White and spiraea Bumald suffer worse. At temperatures of -45-50 ° C, Douglas, Vangutta and Ivolista spiraea perish. In order not to lose the plant, it is enough to tie the tops of the shoots for the winter in a bun. For safe wintering of Nippon spirea, Bumald and Japanese shoots bend, pin to the surface of the ground and fall asleep with fallen leaves.
- Appearance: flowered
- Flowering period: May, June, July, August, September
- Height: 15-25cm
- Color: white, pink, red
Spirea is considered one of the most beautiful shrubs. It is widely used for registration of the local area. It is unpretentious, resistant to winter frosts. Planting and caring for a plant usually does not cause problems. This genus of ornamental shrubs has about 90 species, each of which in the flowering season can be an excellent decoration of the site. Spiraea is planted in well-clarified places, the soil is fertilized. What types of spirea are most popular? How to plan a landing site? How to care for the plant? What problems can an amateur gardener face?
Appearance and biological features
Plants of this genus can grow as small (up to 15 cm) and tall (up to 2.5 m). Shrub branches are erect or creeping. The color ranges from light to dark brown. The roots are shallow, fibrous. During flowering, spirea is covered with numerous small flowers in inflorescences of various forms. The color of the petals - from snow-white to crimson. Spirea inflorescences can be located both throughout the shoot, and on its upper part or at the end of a branch. The plant propagates by seeds, cuttings, dividing the bush, layering.
Spiraea does not need pruning. It is carried out exclusively for decorative purposes, to give the bushes a more aesthetic look. The crown of a plant can be thick and dense or slightly “sparse”, but it always looks attractive. The branches bloom all the way to the ground, so there is no unsightly “bare feet” effect.
The bush is hardy and adapts well to different climatic conditions, so it can be grown not only in the south or in the middle lane, but also in the northern regions. If in severe frosts spiraea freezes, then after pruning it is fully restored and blooms that same year. For the normal development of the plant, a few hours per day of direct sun, top dressing, and good soil are sufficient. You can not cover him for the winter
Spirea blooms on shoots that grow during the same year, so pruning does not spoil its appearance
Spirea varieties of shrubs
All plants of the spiraea genus can be divided into two large groups: spring and letto flowering. Flowering first abundant, but short. Shrubs of the second group do not bloom at the same time, for two months. Flowers have more saturated shades. Low-growing varieties are often used to design alpine slides.
Spring-flowering varieties are covered with flowers in the middle of May. Their peculiarity is that they are all white. Shades can be different, but the color is white. The plants begin to bloom in the second year of their life, they thrive heavily. The most popular are such types of shrubs:
Spirea is gray. The plant received this name not because of the color of the petals (they are white, like all spring-flowering species), but because of the gray-green color of the leaves. This is the most common type of spirea. Flowering period - from May to mid-June. Inflorescences are located along the entire length of the shoot.
Special attention gardeners enjoys spirey gray "Grefsheym." The plant reaches 1.5-2 m, has a spreading crown and white-boiled flowers with a diameter of up to 1 cm, collected in umbrellas inflorescences.
Gray Spirea Grefshaym well "gets on" with Spiraea nipponskoy and arguty, broom, viburnum, hvoynikami
Spirea Wangutta. This hybrid of Cantonese and three-blade spirea reaches 2 m. The flowers are small - up to 0.6 cm, collected in hemispherical inflorescences. Dark green above and dull-gray below the leaves in autumn acquire a reddish tint. This variety can bloom twice - in early June and in August.
Spirea argut. Shrubs plants reach 1.5-2 m, have a beautiful shape. During flowering (from late May to mid-June), spirea argut resembles a white fragrant waterfall.
They buds appear on the ends of young shoots. At the same time last year's branches die. The summer-flowering species is represented by the varieties of Japanese, willow spirea, Bloumald and others. Flowers may have a pink or red color.
To begin, tell you about the Japanese spirea. The bushes in it reach 1-1.5 m in height. The leaves are green above and dull gray below, oblong, ovate, in autumn they turn yellow or red. The flowers are pink-red, gathered in the panicle-like inflorescences. The plant blooms up to 45 days. Common varieties include:
- "Shiroban". Distinctive features of the variety are small leaves (2 cm) and white or pink flowers. It blooms in July and August.
- Goldflame. The leaves of the shrub change color depending on the season - from yellow to copper-orange. Blooms red-pink small flowers.
- Crisp. It blooms from July to late summer. The flowers are small, pale pink, gathered in flat umbrellas.
- "Little Princesses". Low-growing (up to 0.6 m), slowly growing variety. The flowers are large - up to 4 cm in diameter, red-pink, gathered in corymbose inflorescences. The plant blooms in mid-summer - in June-July.
- "Golden Princess". This is one of the varieties of "Little Princess". The variety has a higher bush height - up to 1 m, yellow leaves.
Japanese spirea is one of the most common, but by no means the only Letne-flowering species. Deservedly popular also:
- Spirey Bumald. This is a hybrid look. The plants reach a height of 0.5-0.8 m, have upright shoots and very beautiful leaves - in summer they are green, and in autumn they are yellow, red with a purple tinge. The flowers are pink.
- Among the Spiraeus Bumald, the most common variety is Goldflame. Shrub reaches a height of 0.8 m. If the plant is planted in the sun, then its leaves change color depending on the season - from delicate golden-orange to copper-red. The leaves of bushes planted in the shade do not undergo such changes.
- Spirea is a willow. The variety has long peaked leaves (up to 10 cm) and white or pink flowers. Inflorescences can reach a length of 20 cm.
- Spirey Douglas. The flowering period is July-September. The flowers are dark pink. Bushes grow to 1.5 m tall.
- Spirey Billard. It is a hybrid of the ivy-leaved spirea and Douglas. Shrubs high - up to 2 m. Flowers are pink, collected in long inflorescences. It blooms from mid-summer to frost.
Even before the final selection of the site of planting shrubs should be determined by the desired size and type of plant. Varieties vary in size: they can be compact and fit in a small area, and can grow up and sideways. Therefore, for the solitary landing, decoration of hedges and alpine slides choose different types of plants.
Spirea "Little Princess" looks great in combination with other varieties of Spirea, conifers, lavender. This type is suitable for decoration of flowerbeds, rock gardens, space around water bodies.
Spirea Billard is frost-resistant and shade-tolerant, but it is better to plant it in well-lit areas
Spirea Vangutta gives numerous basal shoots and is perfect for a single planting
For hedges should choose varieties that give little root shoots and are amenable to pruning. Alpine slides can be decorated with slowly growing varieties. And for a single planting it is better to choose plants with developed basal shoots that occupy a large area. For rockeries and stony gardens use dwarf varieties. By choosing several varieties that bloom at different times, a gardener can achieve spirea bloom from spring to autumn cold.
Characteristics of spirea breeding
The shrub propagates both generatively (by seeds) and vegetatively (cuttings, layering, dividing the bush). The first way is laborious. It is used primarily by breeders when working on breeding new varieties. During propagation by seeds, planting material is collected in the fall, sown in special trays with soil and germinated under a perforated film. Planting sprouts in open ground can be made in the spring. The soil should be well fertilized.
Generative reproduction is recommended only for the first-order spirals. Hybrid varieties do not give high-grade seed material. To check the germination of seeds, do test sowing
Vegetative reproduction can be of three types.
Option # 1 - grafting
For him choose shoots 10-15 cm long without flowers, treated with fungicidal solution, after which they are ready for planting in the ground. It is best to plant spiraeus indoors. The soil is moistened, water is sprayed so that the air humidity is about 85%, and the cutting is covered with a film.
The film is pre-prepared - pierce the holes for the flow of air. Place it in 30-40 cm from the planted stem.
Option # 2 - reproduction by layering
The easiest and most effective method. The percentage survival rate of seedlings obtained by cuttings is very high. Spirea branches bend, attach to the ground and covered with soil. Quite quickly, the branches take root, after which they can be cut from the bush and transplanted in the already prepared seedling.
Option # 3 - dividing the bush
This manipulation is usually carried out in the fall or spring. If you want to divide the bush in the spring, then you should choose the period before the appearance of the first buds. Spring breeding spirea has both significant advantages and disadvantages.
The advantage is in the quick inclusion of the plant in growth, the disadvantage is an increased risk of infection of the root system due to warm weather. To solve this problem, seedlings are soaked in fungicidal solution.
General rules for planting spirea
Spiraeus should be planted in slightly acidic, and preferably in pH-neutral soils. The soil should be nutrient rich, with normal aeration. It is better to plant spring-blooming spireas in the fall, and letneretsvetruchivye well take root in the spring and autumn. Many gardeners are of the opinion that the best month for planting flowering varieties is September. Excellent neighbors for spirea can be hvoyniki - spruce, juniper, thuja.
Before planting, cuttings of spirea are soaked in fungicide solution for several hours.
Each variety of spirea has its own individual characteristics, but there are common planting rules for all types. If you stick to them, the plant will take root well and will develop normally in the future. Recommendations from experienced gardeners:
- Planting material must be treated with a fungicide.
- Damaged cuttings should be removed.
- Best planted in leafy or soddy soil. If the soil is poor, it is fertilized by adding peat or a mixture of leaf soil with sand.
- It is necessary to equip the drainage layer with a thickness of 15-20 cm. For this, broken brick, leaf soil, peat with sand will be suitable.
- Planted cuttings should be at a depth of about 0.5 m.
- The root neck should be flush with the ground or recessed 1-2 cm.
- Ideal weather for landing - overcast, rainy.
- After planting the plant in the ground it is watered, sprinkled with peat or sawdust.
The spirea pit should be one third larger than the plant root system. It is dug for 2-4 days and allowed to stand. Then they drain the plant, lower the plant into the pit, throw it with earth and compact it. If the spiraeus is propagated by dividing the bush, then the plant is removed from the ground, placed in water to separate the soil, and then cut with shears into pieces, each of which should have good root lobe and a couple of shoots.
It is better to plant the cuttings first in a pot or tray indoors, and only then in open ground.
Spiraea care - easy
To shrub attractively looked, it is cut and form a crown. The bushes of spherical and pyramidal shape are very beautiful. The specific "haircut" is chosen by the owner, focusing on the overall style of the site design. Pruning does not affect plant development. Remove weak and old (7-14 years) branches. They are cut to stump. It is better to cut the crown in spring, before the leaves appear. If pruned in the middle of summer, the spirea can re-bloom by fall.
After pruning the soil is watered with manure diluted in water. The mixture should be poured under the roots. Fertilize can be a solution of superphosphate. Proportions: 8-10 g of fertilizer per 10 liters of water. Also suitable and "Kemira Universal". On 1 sq.m. make 100 g of granular funds. Spirea does not need intensive watering; it is enough to maintain the plant during periods of droughts. 1-2 buckets of water is enough for normal life of the bush. In winter, the roots can be covered with a 10-15 cm layer of foliage.
Spirea can do without pruning, but it is better to cut it regularly to achieve a beautiful look and well-being of the plant.
Spiraea is susceptible to fungal diseases - ascochytosis, Ramulariosis, and Septoria. You can determine them by the appearance of spots. The plant is recommended to spray Bordeaux mixture, "Fundazole" or colloidal sulfur. The main thing is to process the shrub before or after flowering.
Of the most harmful pests can be spider mites and aphids. The signs of mite “work” are the appearance of holes on the leaves, their withering and falling off, cobwebs. You can cope with a pest by spraying with phosphamide or karbofos. The presence of aphids can be determined by bitten off and faded inflorescences. To combat aphids using pyrimor or similar means.
Spirea can attack snails. How to cope with them, you can learn from the video, which describes the features of pruning and caring for the plant.
Choosing a method of reproduction, it is worth and will take care of good conditions and the place in which the plant will grow well.
Cuttings can be made in the fall, but then they are planted in large pots and put into a room or greenhouse for winter. And the next autumn is planted in open ground.
Planting and care for Spiraea Sulfur
For any variety of Spirea need a sunny plot, it is possible with a small penumbra throughout the day. It grows well in any soil, but does not like wetlands and dry soil.
The planting is carried out in spring and autumn, it is better to plant the plant according to the biological schedule - in the fall, then the plant will quickly take root and bloom faster.
- Dig a hole, which is treated with a weak solution of manganese or a fungicide a day before planting, for disinfection,
- Выкопанную почву смешать с био-удобрениями (навоз, мульча, торф, опилки, зола),
