I love astilba! Such a variety of species, colors and varieties of inflorescences can rarely be found in perennials. It can grow in one place for a long time. For a long time attractive inflorescences remain on its bushes. Unpretentiousness of the plant allows it to grow even the most novice florist. Astilba is appropriate both in the country bed and in the ceremonial flower garden. For those who did not grow it in their plot, we will tell about it in more detail - how the plant looks, what species and varieties exist, how to choose and plant, how to care.
Astilbe (Astilbe) - herbaceous perennial, belonging to the genus of stone-grinding. In the world there are up to 40 species. Such a name was given to the plant by the Scottish botanist Hamilton - “A” means without, “Stilbe” - shine - leaves without shine, dull, dull. East Asia, North America, and Japan are considered the birthplace of astilbe. There perennial grows in moist deciduous forests along streams. Europeans were introduced to this plant by Karl Thunberg and von Siebold. These hunters for unusual plants brought astilba home in the 18th - early 19th century. Since that time, she became the favorite of shady gardens.
Astilbe is a rhizomatous, herbaceous perennial. The grassy part that has grown over the summer dies off in the fall. Erect shoots can grow from 8 cm to 2 m - depending on the type and variety. Serrated simple or feathery leaves sit on long petioles. The color of the leaf plate is from reddish green to dark green. Woody rhizome can be loose or dense, depending on the species. On the upper part of the spring new shoots grow, and the lower part dies. Under a layer of snow, the plant tolerates temperatures down to -37 ° C.
Small white, pink, lilac, purple or red flowers bloom on openwork apical panicles of various sizes. The peak of flowering occurs in mid-summer and lasts about a month. Small seeds ripen in the seed box - 1 g contains up to 20,000 seeds.
Astilbe flowers, depending on the species, are collected in inflorescences of various shapes. They may be paniculate, rhombic, pyramidal, or drooping.
Astilbe with paniculate inflorescences. Its numerous branches with multiple branches branch off from the main axis at an acute angle and shorten to the top.
Astilbe with pyramidal inflorescences - lateral branches depart from the main axis almost at a right angle and evenly shorten from the base to the top, the contour of the inflorescence resembles a regular pyramid.
Astilbe with rhombic buds. Outgoing from the main stem at an acute angle form a rhombus. Such inflorescences are characteristic for Japanese astilbe.
Astilbe with drooping inflorescences in the form of arcs, elegantly hanging from the main axis. These inflorescences are more common in astilba Thunberg and Lemoine.
Decorative varieties depends on the density and size of flowers. Inflorescences with several shades, such as Peach and Cream, Montgomery, White Wings, look especially original.
It contains about 40 varieties bred by crossing David's astilbe with other species. Most of them are tall (up to 1m) plants, spreading pyramid or spherical. White, pink, red or lilac flowers bloom above the dark green leaves. Flowering lasts more than a month from July to mid-August.
It most often does not grow above 80 cm. In compact bushes there are brilliant leaves, inflorescences of panicle pink or white. This species of astilbe begins to bloom before anyone else, dried flowers retain their attractiveness until the end of the season. New varieties are unpretentious to growing conditions, resistant to low temperatures.
Cultivated varieties: Deutschland - white panicles, pink Rhineland, pale lilac and elegant Europe, Montgomery with bright red or burgundy fluffy panicles.
It is a grassy shrub about a meter high. The leaves of different sizes - growing from the base of the bush large, on long petioles, growing on the stem - smaller, with short petioles. Dense inflorescences can grow up to 30-35 cm, most often purple, less white or pink. Can grow in sunny flower beds. The most famous varieties: “Purpurlanze” of an unusual lilac color, pink “Vision in Pink”, “Vision in Red” are dark purple.
Plants of this species and varieties derived from them are very sensitive to elevated temperatures and low air humidity. Drooping inflorescences of these low plants (up to 50 cm) give the plantings a special lightness. Varieties with white candles of inflorescences - Praecox Alba, pink - Bronze Elegans, coral Ostrich feather.
In the 2000s. created a new group of varieties Unic (Younique). This group includes varieties with snow-white, purple Unic Lilac (Younique Lilac), pink Unic Silvery Pink (Younique Silvery Pink) and almost red elegant inflorescences Unic Carmine (Younique Carmine). The inflorescences of these varieties are at the same time openwork and lush, without a long peduncle, growing from the mass of leaves.
When to plant astilba?
In order to admire the astilba bloom every year, it must be transplanted in time and planted.
The end of summer (August) - the beginning of autumn is recognized as the most suitable for this event.
The flowering of the plant has already been completed, and the cold weather is still far away - the plant will have time to take root and prepare for wintering.
The experience of many gardeners recommends seating and dividing astilba bushes in 4 years. A special feature of astilbe can be considered their gradual swelling out of the soil - the rhizomes grow upwards, dying off from below. After some time, the roots become bare. This phenomenon can be eliminated by annual addition of soil or compost to a bare rhizome. Such a procedure allows not to transplant the plant, but only to divide and spread.
Selection of planting material (how to save after purchase before landing)
Many growers purchase astilba seedlings through the Internet or in garden centers. Plants in such trading firms are packed in bags, which in most cases are stored in a dark place. Rhizomes germinate, but the resulting shoots are stretched from a lack of light, resulting in a pale green color and bend. Planted in open ground such seedlings are ill for a long time and poorly take root.
Tip Purchase planting material is as soon as possible, as soon as the seedlings will be on sale. Until planting, store in the refrigerator, periodically checking its condition.
Storing seedlings in a cool place will protect the buds from germination.
Of the entire set of bags with rhizomes, you should choose those that show that the seedlings are alive, the shoots are small, fresh and green. Saplings with long, pale and thin shoots will also take root if the rhizome is not dry and rotted. In the first year of life in a flower bed, such a plant will long adapt to new conditions, will give a weak increase and will not bloom.
The largest selection of astilba planting material in chain stores can be observed at a time when plants are still far from planting in the ground - in February - March. How to keep the acquired rhizomes until the time when they can be planted in open ground?
Astilbe easily transfer home maintenance before planting in the flower garden. One of the storage options is a household refrigerator or basement. Need close to zero positive temperature. Plastic containers with air vents are filled with a moistened substrate - sawdust, coconut fiber, light earth or moss. Rhizomes are placed on the surface and slightly covered with the same substrate. In such a state, astilba will survive until spring without loss.
Rhizomes, which have awakened buds and seeded sprouts can be planted in a flower pot and placed on the windowsill. Water as necessary, not allowing waterlogging. To plant in a flower garden saplings with regrown leaves is necessary after the end of frost. At first, such plants must be protected from excessive sun.
Planting any plant begins with the choice of location. Astilba requires light shading, partial shade. In the open solar glade, astilba will feel uncomfortable. Perennials bloom in such places more abundantly, but ends quickly and shoots have a paler color.
The selection of the planting site is also affected by the flowering time of the seedling. Varieties with early and late flowering bloom equally in the sun and in shading. Shade areas where astilbe will be protected from the hot midday sun are more suitable for medium flowering varieties.
Loamy soil, acidity pH 5.5-6.5, and the surrounding air must be moist. Especially appreciated perennial will be for the proximity of groundwater. Only astilba Chinese will be able to tolerate a slight drying of the soil. For other species, the dried soil of death is similar. A perennial on the shore of a decorative pond will feel very good.
The best spring planting period is May-June.
Preparing the site for planting, they dig it up, remove the roots of perennial weeds, make 2 buckets of organic matter per 1 m2
Cooking landing hole. Its size should be such that the rhizomes of the seedling can be freely located in it. The bottom of the fossa is loose, we pour organic matter, it can be spilled with liquid Biohumus or any other fertilizer diluted according to the instructions. In areas where there may be a lack of moisture in the summer when planting in the soil, you can add hydrogel granules.
Rhizomes are laid on the prepared soil. Planting depth should be such that 4-5 cm of soil is above the base of the sprouts. It is necessary to sprinkle the seedling with the substrate, taking into account that the watered soil will settle and the roots may be on the surface. The hole around the seedling will not allow water to spread over the surface, but will direct it to the roots.
Mulch in the planting hole will retain moisture and facilitate the adaptation of the plant in a new place. Pouring a protective layer of 3-4 cm around the sprouts leave space free from mulch. As such a layer, you can use humus, sawdust, pine needles or shredded bark.
In dry weather, it will be necessary to water the astilba every other day before the appearance of young leaves.
When planting perennials in groups between neighboring plants leave from 40 to 50 cm of free space.
Astilba landing: video
Planted on fertilized soil, astilba grows in one place for up to seven years. With careful care and timely feeding and watering, this period may increase to twenty.
In the spring, after thawing snow planting fertilize. Top dressings in a liquid form get into the root layer more quickly. It is possible to mulch the shoots with organic material. During the growing season it is necessary to maintain soil moisture at the proper level.
When the astilba bloom ends and the flower stalks dry out, it is better to leave them on the plant - even in the dried form they look spectacular. When preparing landings for winter, the above-ground part of the perennial is cut off at ground level and covered by planting. For additional protection of the bush against frost, you can use coniferous spruce branches or vegetable tops.
From the moment of emergence of shoots in the spring and to the middle of summer it is very important to remove weed vegetation in plantings. Toward the end of the summer, the astilba rhizomes expand so strongly that they can choke the weeds on their own.
Diseases and pests
Astilbe, as a stranger from a different climatic zone, did not make a large number of enemies among insects and microorganisms in our latitudes. The greatest harm to this perennial is caused by the penny-bib and two types of nematodes - gallic and strawberry.
Pennitsa in the axils of the leaves creates foam-like nests for their larvae. Under the influence of the pest astilba fades. To destroy the pest can any insecticidal drug.
Damaged by strawberry nematodes, the plants are covered with necrotic spots, they have deformed buds, leaves and flowers.
The gall nematode parasitizes the roots, where gall growths are formed, within which the nematodes live. To notice the parasite on the roots can only be in the second year of life. Plants with nematodes on the roots are lagging behind in development, they bloom poorly and may die. Perennials infected with nematodes should be promptly removed from the flower bed.
Astilba preparation for winter
Prepare the newly planted astilba bush for wintering should be in advance - in the summer. In plants of the first year of life, a new flower site is removed as soon as it separates. Throughout the season, weed the soil around the bush and remove weeds. Loosening the crust on the soil surface should be done carefully, trying to keep young roots intact.
After the first autumn frosts, blackened leaves are cut at ground level and laid on growing bushes. Then an earthen mound about 4 cm high is created above the bush, and then the astilbe grows asleep with dry leaves or peat. Also suitable shredded bark or humus.
On the bushes of the second and subsequent years of life, the flower stalks are left, and for the winter they are similarly warmed with peat or fallen leaves. Every year the astilbe rhizomes rise higher and soon begin to bulge out of the ground, becoming defenseless in the face of winter cold. Frozen winter astilbe become less decorative.
Four to five-year plants of astilba are fully covered before the onset of frost. To begin to cut the foliage and stalks. At the next stage, a framework is constructed in which a heater can be laid - dry leaves or tops. It is possible to fix the leaves in the frame with a spunbond or lutrasil nonwoven fabric. Protect the landing from getting wet with plastic wrap, pressed along the edges.
A strong, healthy plant will more easily endure winter cold and recurrent frosts.
It is possible to increase the immunity of astilbe by applying potash and phosphate fertilizers in the autumn. 50 g of a mixture of fertilizers in a ratio of 1: 1 are scattered under each bush. Good results are obtained by using well-rotted organic matter - manure or compost. Slowly decaying organic matter warms the bush in winter and provides food in an accessible form in the summer.
Astilba seeds are so small that you can see them only through a magnifying glass. To collect 1 g of seeds you need to collect 20,000 pieces. Ripe seeds quickly pour out of the seed pods. To collect the seeds, the inflorescences are cut off in September and put on paper in a warm, dry place, and kept from two weeks to a month. The poured seeds are collected and stored in a paper bag.
With seed reproduction, they start sowing in March. The capacity is chosen wide, about 15 cm in depth. A mixture of peat and sand in a 1: 1 ratio is used as a soil. Snow is poured on the soil with a layer of 1 cm. Natural snow can be replaced with artificial snow - from the freezer. Evenly distribute the seeds on the snow surface by mixing them with a liquid. Seeds are poured into a solution of growth stimulant and pipet seeded on the surface of snow. On a white background, the seeds are clearly visible and you can distribute them more evenly. The thawed snow will moisten the soil, draw the seeds to the desired depth.
After waiting for the snow to melt, the container with the seeds in a transparent bag, and even better wrapped in cling film, is placed in a refrigerator for three weeks. During this time shoots appear in the tank. The green container is transferred to a warm, bright place. Especially carefully you need to water the sprouts - you can water with a sprinkler and a fine spray of water or with a syringe without a needle. Seedlings with 2-3 true leaves are stripped in separate pots, and subsequently planted in the ground.
Reproduction of kidney renewal
- With the beginning of the growth of shoots or buds of renewal, they are cut off with a segment of rhizome.
- Wounds are disinfected with crushed coal or cinnamon powder.
- Segments with buds are planted in a mixture of gravel and peat, in a ratio of 1: 3 and covered with polyethylene (film or cut off bottle).
- In the fall of the current year or in the spring of the next, the saplings are transplanted to a permanent place.
Reproduction by dividing the bush
The easiest and most reliable way to propagate astilbu is vegetatively - by dividing the bush. The best results are given by bushes at the age of 3-4 years. The rhizome of a perennial dug out of the ground is divided into pieces with a pruner or shovel. At least 10 buds should remain on each delenka. The lower parts of the rhizome are removed. The resulting plant parts are planted in new places or wrapped in a damp cloth and kept in a plastic bag, preventing the roots from drying out.
It is better to divide and seat astilba in early spring, before flowering begins. It is necessary to produce the reproduction of perennial autumn in such a way that the plant has enough time for rooting before the onset of frost, i.e. in August and early September. Plants tolerate the procedure of division, quickly take root in a new place and bloom the following year.
Astilba in landscape design
Landscape designers appreciate astilba for a long decorative, resistance to high groundwater levels, the ability to grow in the shadow of tall plants. Openwork leaves sitting on reddish cuttings attract the attention of the entire garden season.
Привлекательно выглядят в цветнике молодые пурпурные листочки, которые постепенно зеленеют и приобретают необычную форму. An additional bonus to the carved leaves is attached long, more than a month, flowering. A variety of shapes and shades of inflorescences adorn the flower garden from mid-summer to autumn.
Astilba in creating flower compositions can be used both individually and in group plantings, combining colors and sizes of different varieties.
Planting in groups
Astilba is a wagon, it will be desirable in any version of landscape design. Low-growing bushes can be used in the foreground of the composition, medium growth will decorate the middle and background plantings. Tall ones decorate what they want to hide, disguise farm buildings or unsightly fence. Low-growing varieties will be appropriate on an alpine slide or scree. They can also frame garden paths.
Landing on flowerbeds
Low-growing varieties of astilbe can be used as a border for flowerbeds and lawns. A bush astilba in a flower pot will decorate an outdoor veranda or garden arbor.
This perennial looks spectacular against the background of conifers, such as thuja or juniper. The successful combination of astilb with hosts and ferns.
Carved leaves of perennial will look even more delicate in joint plantings with hellebore, bergenia, podofillumom, rogersii or cuff. A very interesting combination of astilbe with daylilies, aquilegia, lilies, geraniums, phloxes or ferns. Planted together with the host, astilba emphasizes the beauty of its leaves, and the leaves retain soil moisture for astilba.
The co-planting of astilbe and ground cover plants (stone-sawing, tenacious, and clear) reaches two goals — in early spring, when astils are not yet visible, ground covers create an attractive spot, then grown and color-coded astilbs attract attention. In the hot season, the ground covers protect the astilba growth site from overheating.
In the spring garden, planting astilbe combined with primroses, crocuses, lilies, rhododendrons, tulips.
Planted in the company of tall flowers, astilba masks the bare stems of its neighbors. It belongs to rare ornamental plants that grow and bloom beautifully in conditions of lack of sun and excess moisture. If necessary, astilbe can be planted under the trees, but this should be done by stepping back from the trunk of the tree for at least 1.5 meters. With such planting, the roots of the tree will not be damaged and the astilbe will not be oppressed.
Distillation of astilbe
You can enjoy astilba bloom in winter. For this it is enough to make distillation.
Most readily at home two to three-year bushes will bloom. At the end of September, suitable bushes are dug out and, divided into two - three parts, planted in flower pots with a diameter of at least 13 cm. Substrate need loose and nutritious - sod land, leaf earth, compost and sand (2: 2: 2: 1). Planted plant watered and placed in a greenhouse. In winter, the astilba is planted insulated.
The pot is brought into heat at the end of December and left in a cool place at a temperature not higher than +12 degrees. It is necessary to water moderately. About twenty days later shoots appear. The plant is transferred to a warmer room, where about +20, watering increase. A month and a half astilba may bloom. On one bush can grow to seven full inflorescences.
If the emerging shoots, grown to 8-9 cm, spray growth stimulants, the beginning of flowering will accelerate. Gibbersib allows you to get flowers for 17-21 days, to increase the number of inflorescences and the length of the pedicel. Flowers astilbe become exquisitely elegant.
Subsequently, the bush can be transferred to the open air, and can be grown indoors.
Planting and caring for astilba is simple. Grow this bright perennial and please yourself with astilba flowers.
Characteristics of the appearance and growing conditions astilby
Astilba - It is a rhizomatous plant of the stone-heel family that can live for quite a long time. In the summer, curly-headed shrubs with beautiful buds look quite unusual and decorative, and in winter the grassy part of the plant dies completely.
- Different varieties and types of plants possess height from 8 centimeters to 2 meters. The leaves of the culture of the feathery type, difficult to cut, drilling, or the same green shade. There are varieties that have white, lilac or pink flowers.
- Astilbe's flowering process occurs at the beginning of the summer season and lasts throughout this month. At this time, the plant has the most decorative appearance. Astilbe with curly buds - panicles, are good decorations for parks, squares, gardens and green areas, and are also often used by landscape designers to create unusual areas and to decorate free space. Astilbe in landscape design photo.
- Culture is frost resistant: The root system of this plant can survive the winter, the temperatures of which will reach -37 degrees Celsius without the particular threat of freezing.
It should be noted that when cultivated by the open method, astilbe need wet and saturated with a large number of trace elements soil, also the plant should be subjected to regular watering. If the content of the plant to follow the special instructions, no difficulties in the process of caring for them will not arise.
Where is astilba?
In the wild, the plant can be found in America, East Asia and Japan. In Russia, the main area of distribution of the plant is the Far East, where you can find as many as two different types of astilbe.
Now all cultivated varieties of floral astilbe belong to Arendsa. This variety is distinguished by a medium-sized, as well as tall form, it blooms with bright inflorescences with a pink and white shade, which has a large number of color transitions.
Landscape designers often use varieties of hybrid astilba in design. In the process of flowering bushes form something in the form of a curtain of air pink or purple hue. The plant is characterized by its abundant flowering, as well as rather small and compact size.
Planting astilba hybrid carried out in a group way together with other plant varieties, which makes it possible to shade most of the lawns and coniferous varieties perfectly in the flowering process. The combination of different shades and colors of this culture makes the park plantings more vivid and floral.
Of particular interest is Astilbe Tunnbergwhich has a distinctive look. This variety has drooping brushes of pink or yellow color.
Astilba of early flowering type include a large number of colors and color combinations. So, the colors of white and pink type refer to astilbe japanese. This sort of astilba is distinguished by a particular decorative indicator.
Planting culture and care
When planting plant seedlings, special attention should be given soil quality and its mixtures. In order for the plant to get acclimatized, it needs to determine what requirements the root system of the shrub needs.
It is worth noting that shrub rhizomes in no case should not have rotten or with dead parts. Do not store seedlings in too dry or too wet place. Young shoots should not have a crumpled, elongated or curved shape.
At the same time, planting material with sprouting sprouts can also calmly settle down, but in this case it can be sick for a long time and lose all its advantages and visual appeal.
How to choose a site for planting plants?
It is necessary to remember that astilba prefers places with penumbra, the bright rays of the sun for her are only a negative effect. You should not plant a shrub in open areas that are not fenced off from direct sunlight.
In addition to all this, the flowers are very bad for areas where there is a high rate of groundwater and a long stagnant water. This may cause the plant root system to heal and soak. Growing crops in such an area cannot be done without preparing special drainage. If there is no way to create drainage, you need to choose a higher site for growing the culture.
How to plant astilba in open ground?
The depth of the pit for planting should be based on the individual characteristics of each plant, while need to consider the size of its root system. Astilbe's rhizomes should be located spaciously in the planting pit, and the bush should not be buried or covered with a growing plant.
At the bottom of the prepared pit, you can add an additional hydrogel, which will help keep the moisture inside the soil. You can also add bone meal, ash, and mineral fertilizers to the bottom - just one matchbox is enough.
The surface of the earth can also be further multiplied. peat or bark, which will help keep the surface of the soil evenly dry, and in the future will protect the root system of culture from drought.
Process care culture
In one year, astilba bushes are able to grow by 3-5 centimeters in height. The main parameters for the care of the culture is soil bedding for bare root systems. Fertile soil at the same time should be added with a layer of 2–3 centimeters.
The care of the plant also includes the maintenance of soil moisture indicators. To do this, add a mulch layer (of expanded clay, peat, bark, as well as landscape rubble) over the planting soil to the soil. Astilbe preparation for winter: in the winter, mulch the soil surface is in order to save the plant root system from freezing.
The combination of regular watering and soil conservation in a moist state - These are the main factors that will help the plant look magnificent and bloom at a special speed.
To maintain the ornamental level of the plant, it is possible to periodically trim the crown of plants, as well as remove dead or defective stems. Wherein should be quite often removed from the culture of old inflorescences, it is especially necessary to make it in landscape design, in the process of decorating the lawn and free space.
How to fertilize and feed the culture?
Fertilizer culture in the spring season and during planting was mentioned above.
In order for the plant to grow and develop fully, it needs to make regular fertilizing with fertilizers, including a large number of vitamins and minerals. While astilbe grows freely in one area without transplanting and dividing the root system for five years, it is necessary to feed the culture with a fertile mixture even in early spring. This contributes to the rapid growth of new foliage on plants that have already wintered.
Do not forget that this crop needs to be fertilized with special mineral fertilizers.
In the process of flowering, the plant needs phosphorus fertilizers, and at the end of flowering, from potassium. It helps to increase the flowering time, as well as the splendor of flowers. Fertilizers can improve seed formation. Care for astilba in the fall is done in the same way.
To preserve the varietal characteristics of the culture and its decorative qualities, it does not need to be propagated by perennial seeds. Plants produced by seeds, most often do not correspond to the description and official features:
- have different color and color,
- sparse floral tassels,
- have a low decorative rate
- short flowering period.
For seed propagation it is important to use only seeds with proven and high quality varietal selection.
Culture seeds are usually sown in the ground, previously well-moistened. In order for them to germinate as quickly as possible, you need to maintain a constant indicator of humidity (you can cover the shoots with glass or grow them in a specialized greenhouse). Also when growing crops regular watering is very important. In this period it is very dangerous to overdry young sprouts. It is necessary to limit them from the effects of direct sunlight, but at the same time provide for them a fairly bright place.
Good germination rates occur when using harvested seed stratification. This agrotechnical method involves placing seeds in a rather cold place for three weeks. The obtained seeds must be sown in a greenhouse with a temperature of + 20 degrees Celsius. Young sprouts already after 2-3 months after sowing will become suitable for transplanting to a permanent growing area in open ground. The seedlings obtained from stratified seeds are characterized by a special growth and survival rate.
How does culture grow through shrub dividing?
The division of astilbe by the vegetative method is considered for florists as the most common and most reliable method.
The mother plant is dug out with extreme care, trying not to disturb the structure of the root system of the plant. A sharp knife should divide the root system of the culture into several parts with 2–3 buds. Places of cuts should be covered with coal.
In the pre-created hole should expand the resulting planting material, and then - moisten the soil. Particularly good results when planting a summer bush can be achieved by using stimulants of increased rooting with it. Care of the crop includes frequent loosening and watering the soil.
Landing astilby division foresaw in early spring, starting in March. With this method of reproduction, the first flowering of the culture arises already in early autumn.
Multiple astilba can also be another method, the simplest and fastest - the division of the kidneys. In spring, with the onset of the growing season with a sharp knife, flower growers separate kidney renewal. Cuttings need to be planted in a greenhouse with a wet soil in a mixture with coarse sand and gravel, powdered places cut using ash. With this method of reproduction, you can achieve high rates of young shoots. One disadvantage of this method is that you can get a full-fledged shrub only after one year.
Head pests and infections
- Astilba is able to attract gardeners not only with its decorative and pleasant look, but also with the fact that it is not completely damaged by diseases and parasites. The root system of some crops may be affected by the gall nematode. In this case, the insect does not react to the use of any drugs. To get rid of nematodes, it is necessary to completely destroy the diseased shrubs. In this area it is better not to plant crops over the next three years.
- Another parasite that can easily harm a plant that grows in open ground is considered to be a slobber. Struck bush feels extremely uncomfortable, slows the development of all the foliage. The main method of dealing with drooling captive is to collect the pest from the surface of the leaves manually.
- Be sure to carefully monitor the health of this ornamental plant. If it is exposed to the threat of pests or infections, it is imperative to begin an active and immediate fight.
The plant is used for both single and group plantings and to create special landscapes for shady and semi-shaded areas.
This is a perennial rhizome plant, which has decorative inflorescences of white, pink and lilac color. Depending on the variety such plants can have a height of 10 centimeters to 2 meters.
Astilbe blooms, depending on the specific species, begins in May or early summer, and lasts for a month. It is during the flowering period that such a plant is extremely decorative, which makes it possible to use it to decorate gardens, park areas, squares and homestead lands. You can pick up different types of astilbe, which differ in their timing of flowering. With the right choice of such varieties of plants in the garden will constantly bloom and smell.
This culture has excellent frost resistance.. In the autumn, the aerial part dies completely, and the rhizomes are able to withstand winters with temperatures as low as -40. Accordingly, gardeners will not be required to additionally mulch or cover plantings with any heat-insulating materials.
Japan, East Asia and North America are considered to be home to this plant. In Russia, wild astilbe is found in nature in the Far East. All cultivated varieties, which are widely used in landscape design, belong to the astilba lerens species. Depending on the specific variety, you can choose medium and tall forms of this plant. They usually bloom white and pink buds with numerous transitions of shades.
Astilbe hybrid is widely used in landscape design, which is distinguished by the colors of purple and pink. These varieties have compact dimensions and characterized by abundant and long flowering.
We can also recommend you to pay attention to the variety of Tunberg variety, which differs by drooping inflorescences with pinkish and yellow flowers that are unusual for this species. Этот сорт относится к поздним, поэтому его цветение обычно приходится на конец июня и начало июля. А вот из раннецветущих можем порекомендовать вам астильбу японскую, которая отличается великолепной декоративностью.
Посадка и уход в открытом грунте
When planting these ornamental plants should be given due attention to the choice of quality planting material. Attention should be paid to the condition of the rhizome, which should not have obvious signs of damage. In this case, one hundred percent survival rate can be guaranteed. plants in a new place. A gardener only needs to decide on when to plant a flower culture. Plant in the open ground young rhizomes can be at the end of spring.
Important. Young shoots of astilbe should not be curved, wrinkled or stretched. Excessive moisture and overdrying of planting material during its storage is not allowed.
First of all, you will need to determine when it is possible to plant and choose the right place for planting. This plant loves penumbra, so bright sunlight is disastrous for him. It is also undesirable to plant this flower in unprotected from the sun open spaces.
Noticed that astilba is bad grows in areas with high groundwater levels. Also, it is not recommended to plant this flower crop on soils with stagnant water, which leads to dampening and wetting of the rhizomes. In the event that your site is located in a valley, then it will be necessary to perform high-quality drainage, which will allow to avoid certain difficulties in growing astilbe.
Plant astilba in the open ground in the spring can be prepared in advance holes, the size of which depends on the size of rhizomes. Remember that the root system of the plant should be freely placed in a dug planting pit. It is recommended to lay drainage and hydrogel on the bottom of the pit. Subsequently, the presence of such a hydrogel retains the soil moisture, which improves the growth rates of astilbe. The following fertilizers should also be added:
- Wood ash.
- Nitrogen fertilizer.
- Potassium-containing fertilizers.
Immediately after planting, the soil can be mulched with peat chips or crushed bark. This will keep the soil evenly moist and protect the roots from drying out.
Proper care of plants
Planting care is not particularly difficult. DThe owner and gardener will only need to do the following:
- Regularly water the plants.
- Remove weeds.
- Feed seedlings.
- Loosen the soil and sprinkle bare rhizomes.
It is the proper irrigation of astilbe that should be given due attention. It is recommended to carry out this procedure weekly, evenly moistening the soil, but at the same time avoiding waterlogging of the soil.
Pay attention to the root of the plants. Quite often the roots with the growth of astilbe become bare, which impairs the growth of this flower culture. It is necessary once every few months to perform rhizome powder, adding a fertile soil with a layer of about 2-3 centimeters.
Mature plants have excellent frost resistance. Therefore, any additional warming astilbe in the winter season is not required. But the rhizomes of young plants can still freeze slightly, so for the first few years it is advisable to carry out the mulching of the landings, and in late autumn just before the snow falls, cover the area with insulating materials.
Gardener will have to perform pruning dead stalks. Correctly and promptly performing pruning, it is possible to form any kind of plant crown in appearance, preventing the thickening of plantings and achieving the maximum possible decorative effect. When using astilba for registration of the local area, it will be necessary to regularly remove dead inflorescences, which will ensure rapid growth and high-quality flowering.
Astilba is an unpretentious decorative plant that can be grown, which can be grown even without additional feeding. However, regularly feeding a flower culture can not only guarantee its rapid growth, but also abundant flowering. For the full development of this plant will require regular fertilizing mineral complex fertilizers.
In the spring it is recommended to make nitrogen fertilizers, which allows overwintered bushes to get the necessary nutrition and quickly increase the green mass.
During flowering, it is recommended to use phosphorus-containing mineral complexes, which makes it possible to prolong flowering, while the plant itself is not depleted and continues its active growth.
At the end of the flowering period, it is recommended to add potash fertilizers, which provides plants with nutrition and stimulates the formation of numerous full-fledged seeds.
With seed reproduction astilba Gardeners may face some difficulties. The fact is that ornamental flowers grown from seeds often do not match the characteristics and appearance of the mother plants. So, for example, astilba grown from hybrid varieties of seeds differs:
- Short flowering period.
- Mediocre decorative.
- It has sparse floral tassels.
- The color of the inflorescences may differ significantly from the parent.
That is why for such reproduction should use seeds obtained from plants of varietal selection.
Such seeds should be planted over the entire surface of the moistened soil, with no need to embed the seeds. To accelerate germination, one should maintain a high soil moisture, for which the earth is watered daily and abundantly. In the future, you only need to regularly water the sprung seedlings and protect them from direct sunlight.
Popular vegetative method of reproduction by dividing the bush, which allows you to get the daughter plants, which in their appearance and characteristics fully correspond to the mother bushes. When digging up the mother bush, care should be taken, as there is a danger of damaging the tender rhizome. Large size maternal rhizomes should be divided with a sharp knife into several parts with two or three buds. Slices made must be powdered with crushed coal.
Separated rhizomes should be planted in prepared furrows, and the ground should be watered abundantly. Also, with such reproduction by dividing the rhizome, it is possible to water the plantings with water with the addition of root stimulants. Care of planted bushes consists only in regular watering and loosening of soil.
Important. Reproduction astilby division of rhizome can be performed in early spring or autumn.
Common diseases and pests
When growing this ornamental plant, gardeners may encounter various diseases and insect pests. The success of the fight against such pests and diseases depends largely on how quickly treatment is started. That is why it is necessary to regularly inspect the flowering plants for the detection of various insects or signs of disease.
Rhizomes can be affected various nematodes that can quickly multiply, destroying all plantings in the bud. It should be said that the nematode is extremely resistant to the introduction of various drugs, so the fight against this pest is the destruction of diseased bushes.
Of the pests also note such an insect as a slobbering pennitsa. This pest can be identified by the characteristic saliva-like formations on the leaves. Affected plants slow down in growth and look depressed. The fight against these insects is the manual collection of pests from the leaves.
Of the common diseases, we note only fungal lesions, which can occur when excessive watering of plants. That is why irrigation is necessary. planting perform carefully, observing the state of plants.
Astilba is a decorative flower culture, which thanks to the ease of its cultivation, is loved by summer residents and owners of private houses, who were given the opportunity to effectively decorate the local area. Today, there are various varieties of astilbe, which are distinguished by a shade of flowers, their size and timing of flowering. Planting and subsequent care of astilba is not difficult, so every summer resident gardener can handle this job.
Garden beauty astilba
Astilbe is a herbaceous ornamental perennial, various species of which have come from Asia and North America. Depending on the cultivated variety, the height of the plant can vary from 20 cm to 2 meters, the shades of tiny flowers gathered in paniculate inflorescences are incredibly diverse. Well-chosen plants will cover the garden with a cloud of white hues of white, pink, red, purple and lilac. The leaves, like inflorescences decorative. Not only that they have a refined falsely dissected shape, the color of the leaf plates varies from the usual green to burgundy or purple-gray.
If you make a little effort in the cultivation and care, astilba, as in the photo, from June to August will surprise with friendly and long flowering.
Astilba in the open field - a very grateful plant that responds well to attention, proper selection of a site for planting and fatigued care. This is one of the few cultures that not only tolerate, but also prefer penumbra. Astilba has very few enemies in the garden, and the flower is rarely affected by diseases.
When to plant astilba in open ground: in spring or autumn
After hibernation, the plant wakes up somewhat later than the other perennials. In order for astilbe to start a stable growing season, the average daily air temperature should not fall below +10 ° C. In warm areas, the young leaves of astilbe appear in late April or early May during planting and caring in open ground.
In the north, where the spring is delayed, the development of the plant is delayed until the end of May or the beginning of June.
If the florist wants to replenish his collection of luxurious plants, it is important not to hurry, so that the flower culture does not freeze after transplanting, and not to delay. Otherwise, in hot weather, astilbe will be more difficult to acclimatize.
The beginning of the growing season is the time when it is better to plant astilba in the spring in the open ground.
Some summer residents practice autumn planting of a flower, but in this case the plant should be given time to root and adapt to a new place.
Place for planting astilba in open ground
When choosing a place for astilbe, you need to remember that the plant:
- prefers diffused light
- can grow and bloom in the shade of trees and buildings,
- unpretentious when choosing a soil that must hold moisture well and not be excessively heavy,
- However, it does not tolerate stagnant moisture, which threatens to rot the roots, and in springtime increases the risk of prela.
So that the flowering perennial does not suffer from too dry air, in order to plant astilbe in open ground and facilitate care, it is useful to choose areas near water bodies where the humidity is somewhat higher.
Features planting astilba flower in the ground in spring
On the flowerbed, the place for astilbe is calculated so that between bushes there is about 30–40 cm. Add to the previously prepared landing holes with a depth and width of 30 cm:
- 30 grams of complex fertilizers for ornamental crops,
- about a glass of bone meal,
Planting is carried out in a moistened soil to a depth of about 20 cm, while at the same time over the points of future growth the soil layer should not be more than 3-5 cm.
Planted adult plants and delenks during vegetative reproduction of astilbe are densely mulched on top, so that the soil retains moisture better, and the plants are protected from weed vegetation.
As mulch fit a variety of materials, which include:
- chopped straw,
- large chips or pieces of bark,
- pebble or expanded clay,
- lowland peat.
As needed, the mulch layer is renewed in the summer, and when planting astilba in the open ground in the fall, it helps the perennial crop to winter easily.
When it is useful to plant astilba in open ground in autumn?
The peculiarity of the astilbe is the upper growth of the root system, which in a few years leads to the appearance of a dense island under the bush that rises above the general level of the soil. Without a regular, once every 4–5 year transplant:
- Astilbe's roots weaken
- decreases the number of annually generated kidney renewal,
- the flowering of such a plant is shorter and poorer, the leaves are smaller.
After flowering of adult astilbe, it is useful to undertake its autumn transplant, combining the procedure with dividing the bush into several young ones.
If you are to plant and care for astilba in the Urals, in Siberia, the Non-Black Earth, you need to calculate the time of transplantation so that the plant has time to acclimatize. Autumn mulching, which partially replaces or enhances the effect of flower cover for the winter, will be a good help.
Vegetative reproduction and planting astilbe seeds
In conditions of an amateur garden or suburban area, astilbe reproduces vegetatively, that is, by dividing an adult shrub or by using individual renewal buds. Planting astilba seeds - a rarity used to produce new varieties or hybrids, as well as in the presence of varietal seed.
The easiest way to divide the adult bush. This is done in spring or autumn so that each part has several promising growth points and enough roots for food.
Place the slices on the root system should be treated with crushed charcoal. Planting in open ground and care for astilba in this case have no special features, except that young specimens are watered every day. If you don’t be late with a transplant, in the second half of the summer, astilba will please you with the first colors.
The separation of promising buds, which will become an independent runaway next year, will also help to get a young astilba. And here it is worthwhile to take care that the renewal kidney has a healthy root.
The future bush is planted on a separate rassadnuyu bed in a loose moisture-absorbing substrate. Often use film cover. They will help maintain a comfortable temperature, high humidity and help the plant to take root faster. In the fall or the next vein, these seedlings are ready for planting on a permanent place.
Care of astilba after planting in open ground
Caring for a beautiful astilba will not complicate the busiest summer resident. If the site for planting is chosen correctly, during the spring, summer and autumn, while vegetation is in progress, the flower requires:
- irrigation, providing the plant with his favorite water,
- top dressing with predominance of potassium and phosphorus,
- measures to maintain cleanliness and looseness of the soil, for example, maintaining a layer of mulch.
We can not allow the soil under the astilba covered with a dry crust. The plant immediately responds to this with listlessness of leaves, shedding of flowers and "tears" in lush inflorescences.
Astilba is not afraid of cold, so in most regions it is not specially covered, but it is worth checking the layer of mulch in the fall. When spring comes, mulching is done again. It will save shoots from frosts and simplify the care of astilba after planting a flower in the ground.
Experienced flower growers who have long grown a crop, recommend removing fading buds along with flower stalks. This measure will save astilbe forces and improve the appearance of the entire flowerbed. Before the onset of cold weather, the above-ground part of the plants is carefully cut, leaving petioles 5–10 cm above the ground level.
