The astilbe herb is a member of the stone-heel family. The first representatives of this culture grew in Japan, East Asia and North America. There are about 40 species of this plant and more than 400 varieties.

  • The height of the bush can vary from 1 to 2 m.
  • In the panicle inflorescences with a length of 10-60 cm flowers are collected. The color of flowers can be very diverse: white, red, pink and purple.
  • The color of the foliage can be dark green, burgundy, bronze.
  • In the form of a fruit - a box with small seeds.
  • Flowering period - from June to August.

Astilba varieties

More than 400 varieties of astilba, differing from each other in size, color of flowers and the shape of the leaves were bred by scientists. The most famous and popular species include:

David The bush can reach a height of 150 cm. The inflorescences are located horizontally, they look down, the flowers are lilac-pink. Flowering period from July to August.

I was able to get rid of ARTHROSIS AND OSTEOCHONDROSIS PER MONTH! Operations are not needed. Read more here.

Naked. Plant height up to 20 cm. Flowering - in June, July. Foliage has a bronze tint.

Chinese The bush can reach a height of up to 100 cm. The flowers of the plant are pink, lilac or white, and the leaves are covered with reddish fluff. Inflorescences have a length of up to 30 cm. The flowering period lasts from June to August.

Japanese Reaches in height about 70 cm. The bush well expands, forming a circle of wide diameter. Inflorescences up to 30 cm long, diamond-shaped, flowers are pink, red, white.

The flowering period is midsummer. This variety is resistant to cold, as well as the fact that it survives well.

Thunberg. The height of the bush is up to 80 cm, the flowers are white, the edges of the leaves are serrated. Inflorescences are rare, look down, panicle width 10 cm, length - 25 cm. Flowering period: July-August. This variety belongs to the pyramidal form; it is distinguished by the spreading of shoots covered by dense foliage. The species reacts poorly to low humidity and heat.

Preparing for landing

It is advisable to choose a site for planting astilbe with close adherence of groundwater. The plant can also be planted on the shore of a pond located in the garden. Since the sandy soil retains moisture poorly, the area must be mulched with peat from above.

Recommendation! Before planting the land on the site should be dug up, remove the roots and add organic matter.

If astilba was purchased in a store, then before planting, rhizome should be soaked in warm water for 1 hour. It is recommended to add potassium permanganate to the water so that the solution turns pale pink.

Dividing bush

Even old bushes can be used for breeding, because after the procedure dormant buds wake up on them.

To carry out the procedure of division should be more often 1 time in 3 years. Dig the plant should be in early spring - in March, or in late August.

Propagating the bush with the help of division, it is necessary to ensure that each delenki was 3-4 buds. The rhizomes are divided into 4-5 parts and planted on a new site, observing a gap of 35-40 cm between the bushes. Place the slices on the roots treated with crushed charcoal.

Kidney renewal

  1. In early spring, when the young shoots have not yet had time to grow, with a sharp garden knife it is necessary to cut the buds from the beginning of the rhizome, and then process the cuts with wood ash.
  2. Planting material obtained in this way is planted in a mixture consisting of 3 parts of peat and 1 part of gravel, then covered with a film to create a greenhouse effect.
  3. Then you should wait for the rooting of the shoot, which occurs within 3 weeks.
  4. Young and mature bushes are transplanted to a permanent place in early autumn, or next spring.

Cuttings

  1. After the bushes reach a height of 10-15 cm, they can be cut and divided into cuttings.
  2. Then shoots should be planted in a box filled with a mixture of peat and sand in a 1: 1 ratio and watered.
  3. After which it is necessary to spray the plant from the spray gun 2 times a day.
  4. During rooting, you should maintain the air temperature in the range of 20-22 degrees.
  5. Peduncle formed on the handle should be removed.

The method of propagation by seeds is used most often for selective work, since they do not germinate well.

  • Sow the seeds in the garden should in the spring or in the fall, not falling asleep their ground. The location for the plant, it is best to choose in the shade.
  • The first shoots appear in 10-15 days, and if they were sown in the fall, in the spring.
  • After the plant has the first true leaf, seedlings should be seated at a distance of 15 cm from each other.
  • Fortified bushes can be planted in a permanent place.
  • Young planting for the winter is covered with foliage.

When propagating from seedlings, pre-stratified seeds should be sown at the beginning or in the middle of March.

  • Seed material is placed in a container for planting a depth of 15-17 cm with a sand-peat mixture, covered with a layer of snow.
  • Melting snow will gradually moisten the soil and allow the seeds to sink to the required depth for cultivation.
  • Crops for 3 weeks should be placed in a cool place, previously covered with a film.
  • After sprouts appear the first true leaves, it is necessary to carry out a picking procedure.
  • Care of the plant in the future, is to conduct watering and compliance with the temperature of 20-22 degrees.

Diseases and pests

The plant very rarely falls prey to diseases and pests, in rare cases it can hit:

  • slobbering penny
  • gall nematode,
  • strawberry nematode.

The pennica is usually located in the leaf sinuses of the plant. After some time inside them salivary discharge in the form of foam, inside which are located the Tsikadki larvae. Affected leaves shrivel and become covered in yellow spots. Bush at the same time fully or partially fade.

In order to get rid of this pest, you should use:

  • Rogor,
  • Confidor
  • Aktar (2-3 g per 10 liters of water),
  • Karbofos.

The buds, flowers, leaves of the plant are subject to the settlement of strawberry nematode. Affected areas of the bush are deformed and covered with necrotic spots of brown or yellow color. Astilba growth worsens.

The gall nematode most often affects the roots of the plant and manifests itself in the form of small galls (growths) on their surface, within which the nematodes are located. Galls differ well in the second growing season. The flowering and growth of the affected bushes noticeably deteriorates, in some cases the plant dies. Therefore, shoots that have obvious signs of the disease, it is necessary to dig and destroy.

Important! In the first growing season it is very important to carry out the first weeding on time. In the second vegetation period, the overgrown plant root system will independently damp the weeds.

It is recommended to treat Astilbe Fitoverm.

Young foliage plants sometimes suffer from frosts that occur in late spring, but this can not be an obstacle to the emergence of new leaves and flowers. Astilba perennial tolerates harsh winters, but suffers from spring frosts and wetting. The plant is suitable for growing in regions with adverse climatic conditions, including in the Urals, in Siberia.

Important! Varieties that have the greatest ornamental value, with large inflorescences, can freeze slightly.

Botanical description

Astilbe is an herbaceous perennial plant of the Stone-hem family. Under natural conditions found in North America, China and Japan. It prefers deciduous forests, river banks and streams. In Europe, the flower is grown from the XVIII century. The plant adorns the shady areas of gardens and greenhouses.

The flower has a powerful rhizome, the aerial part dies off in late autumn. Stems erect plants, reach 2 m. The leaves are green, sometimes with a reddish tinge, petiolate, simple or pinnate.

Astilbe flowers are collected in apical inflorescences in the form of a panicle or pyramid. The color scheme includes white, pink, red, purple hues. Flowering, depending on the variety begins in June - August.

Astilba Arends includes more than 40 varieties. The varietal group is characterized by powerful sprawling bushes up to 1 m high. The inflorescences are in the form of a ball or a pyramid, white, red, pinkish. Flowering begins in July and lasts for 40 days.

Chinese hybrids reach a height of 1.1 m. The leaves are large, inflorescences up to 40 cm long. The flowers are purple, purple or white. Representatives of the group grow well in the lighted areas.

Photos of Chinese Purpurlanze flower variety:

Japanese astilbe has a height of up to 80 cm. Pink or white paniculate inflorescences bloom in June. All varieties are resistant to cold snaps.

Prostolistnaya astilba - a compact plant up to 50 cm in height. The drooping inflorescences look spectacular on the site. The color scale is presented by white, pinkish and coral shades.

Astilba looks good in group and mixed plantings. Low-growing varieties are used to design borders and reservoirs. The plant is combined in geyhery, hosts, fern.

Seeds of Gavrish, Center-Ogorodnik, Agronika, Aelita manufacturers are on sale. Agrofirms implement both individual species of plants and their mixtures.

Planting seeds

There are certain terms when plant astilba on seedlings. Works are carried out in March-April. First, prepare the substrate and process the seeds. For cultivation astilby take equal amounts of sand and peat.

Soil mixture is steamed in a water bath to destroy pathogens. Another option for disinfection is to place the soil in a refrigerator. At sub-zero temperatures, the ground is kept for several months on the street or balcony.

For disinfection planting material is placed in a solution of Fitosporin. The use of the drug allows you to grow healthy and strong seedlings. s

For the cultivation of astilbe from seeds, containers with a height of 15 cm are prepared. To avoid picking up seedlings, cassettes with a cell size of 5 cm are used.

Seed planting procedure:

  1. Tanks are washed with hot water and filled with primer.
  2. A layer of snow 1 cm thick is poured on top. In the absence of snow cover, you can use their freezer ice.
  3. Astilba seeds piled on snow.
  4. After the snow melts, the seeds will be in the ground. Then the container is wrapped in a plastic bag and left in the refrigerator for 20 days.

Changes in temperature stimulate seed germination. When shoots appear, the containers are transferred to a warm, lit place.

Conditions for seedlings

Astilbe seedlings provide a number of conditions that include temperature, soil moisture and light.

Microclimate for growing astilby from seeds at home:

  • temperature 18-23 ° C
  • lighting for 12-14 hours
  • regular watering
  • airing the room.

If the duration of daylight hours is insufficient for seedlings, then the installation of fitolamps or fluorescent devices is required. Lighting placed at a distance of 30 cm from the seedlings. Lamps include morning or evening.

Plants are watered with warm settled water. Moisture is applied under the root to dry the topsoil. To avoid high humidity, the room is periodically ventilated. Landings cherish from drafts.

With the development of 2-3 astilbe leaves, it is seated in separate containers. To minimize stress on plants, they are transferred to new containers along with an earthy clod.

2-3 weeks before transferring to the ground start hardening seedlings. Plants keep a few hours on the balcony or loggia. Gradually, this period is increased. Hardening will help astilbe to quickly adapt to the natural environment.

Landing in the ground

When growing astilba from seeds, it is transferred to the garden bed in May-June after the warm weather has been established. For plants fit the northern areas that are in the shadow of buildings or fences.

The flower develops well next to trees and shrubs. When planting on the illuminated site astilba blooms profusely, but less long.

The plant prefers loamy soil. The high location of groundwater provides soil moisture. In the spring, the plot is dug up and fertilized with compost in the amount of 2 buckets per 1 square meter. m

When planting astilba seedlings in open ground depends on the climatic conditions of the region. It is necessary to wait for warm weather and the last frost.

The procedure for planting seedlings in the ground:

  1. Preparation of planting pits with a size of 20x20 cm and a depth of 30 cm. A 30 cm gap is left between the plants
  2. At the bottom of each pit pour 1 tbsp. l diammofoski and 1 cup of wood ash.
  3. The wells are plentifully watered.
  4. Seedlings also watered and taken out of containers.
  5. Astilba is placed in a pit, growth buds are deepened by 4 cm.
  6. Roots of plants covered with earth, which is well tamped.
  7. The soil is mulched with peat, layer thickness - 3 cm.

Astilba care

Astilba is an unpretentious plant that requires minimal maintenance. At one place the flower grows 5-7 years, with regular care, this period reaches 10 years. Planting watered and periodically fed. Late autumn plants are prepared for winter.

During the season you need to monitor the soil moisture. The intensity of watering astilba depends on weather conditions. With abundant precipitation, watering is minimized. In a drought, the plant is watered 2 times a day.

Photos of astilba colors:

After watering, the soil is loosened and weeds are weeded. After loosening, plants better absorb moisture and beneficial components. Shrubs recommended spud.

Astilba, grown from seeds, responds positively to fertilizing. During the season, fertilizers are applied 3 times:

  • spring after snow melt
  • in mid-June,
  • after flowering.

Nitrogen fertilizer is prepared for the first feeding. Nitrogen stimulates the development of new shoots. When hilling in the ground make rotten compost. Of the mineral substances used for plants, urea or ammonium nitrate. 20 g of the substance is dissolved in 10 l of water, after which watering is performed.

The second treatment is carried out using potassium nitrate. On a bucket of water take 2 tbsp. l fertilizer. After flowering, the plant is fed superphosphate. 25 g of the substance is embedded in the ground or added to the water during watering.

Autumn work

Astilba inflorescences long retain decorative properties. Therefore, they are not cut, and left on the bushes in semi-dry form.

At the end of the season, plants need special care, which will prepare them for winter. The stems of the flower are pruned under the root.

The plants are mulched with dry leaves and covered with spruce leaves. If there is a lot of snow in the region, additional cover is not required. The flower tolerates frosts to -35 ° C.

Conclusion

Astilba is an unpretentious plant that blooms profusely in the shade. The flower is grown from seeds that are planted at home. Seedlings provide a number of conditions, including temperature, watering and lighting. Grown flowers are transferred to a permanent place. When feeding and making moisture astilba pleases with abundant flowering.

Description of the plant - varieties and varieties

Astilbe is a rhizomatous perennial of the stone-heel family. In the summer, curly bushes with pretty buds are very decorative, in winter the grassy aerial part of the plant dies off. Different varieties of plants have different heights - from 8 cm to 2 m. Astilbe leaves are pinnate, difficult to dissect, green or brownish in color. There are varieties with white, pink and lilac flowers.

Astilbe begins flowering in early summer and lasts for about a month. During this period, the plant is the most decorative. Astilbe with curly inflorescences - panicles - serve as an excellent decoration of park areas, gardens, squares and are often used for decoration of territories in landscape design.

The culture is characterized by high resistance in winter: the rhizomes withstand wintering at temperatures up to -37 ° C without the threat of freezing.

Important! When grown in open ground, astilba prefers moist, nutritious soil and even periodic watering. Subject to this condition, care for the flower crop does not present any particular difficulties.

Areas of distribution of natural species of astilbe

In nature, the plant is found in Japan, America and East Asia. В России ареал растения – Дальний Восток, где встречаются 2 вида астильбы природных сортов.

Все современные культивируемые сорта цветочной культуры относятся к виду — астильба Арендса. Srednerosly and tall forms of a plant blossom bright inflorescences of pink or white flowers with numerous transitions and shades.

In landscape design is widely used astilba hybrid cultivars. During flowering bushes form air curtains of pink or purple hues. Plants are characterized by compact size and abundant flowering. Planting astilba hybrid in groups with other species allows lawn and coniferous crops to shade perfectly during flowering. The combination of plants with different tones of coloring revives the territory of park plantings.

An interesting type of astilba Tunberg, which is not characteristic of the species, drooping brush yellowish or pink flowers.

Early flowering astilbees of a wide range of colors of white and pink hues belong to the Japanese astilba species. This type of astilba is distinguished by high decorativeness.

Astilba: landing and care

When planting plants, the quality of planting material is of great importance. To plant survival was one hundred percent, it is worth considering some of the requirements for rhizomes intended for planting.

Of course, specimens with sprouting sprouts can also take root, but then the plant can lose its decorative effect and be ill for a long time.

Choosing a comfortable place for a flower

It should be remembered that astilba is a plant for penumbra, bright sunlight is destructive for it. Planting flower culture in open, unprotected from sunlight spaces is undesirable.

In addition, the flowers react poorly to areas with high groundwater levels and water stagnation. This leads to soaking and decay of rhizomes. Growing crops in such areas will not do without a reliable drainage device. And if it is not possible to equip it, you need to choose a higher place for planting.

Planting astilba in the open field: determine the size of the pits

The depth of the planting pit is required to be provided individually for each plant, given the size of the rhizome. The root system of astilbe should be placed freely in the planting pit, while the bush should not be buried or the growth point should be filled with soil. At the bottom of the pits, you can add a hydrogel, it will help to preserve the moisture of the soil, as well as bone meal, ash and mineral fertilizers - 1 matchbox each.

The surface of the ground is allowed to be barked with bark or peat crumb, which will keep the soil evenly moist, and in the future it will protect the roots of the plant from drying out.

Plant Care

Astilba shrubs grow by about 3-5 cm in height in a year. Measures for the care of plants are reduced to adding soil under the exposed parts of the rhizome. Fertile soil is added in a layer of 2-3 cm.

Planting care requires maintaining soil moisture. To do this, add a mulch layer (peat, bark, expanded clay or landscape rubble) on top of the planting soil. In winter, mulch on the soil surface helps protect delicate rhizomes from freezing.

The combination of uniform irrigation and preservation of soil in a wet state is a guarantee of plant health and lush flowering.

Decorative plants supported by periodic pruning of dead stems. It is necessary to regularly remove faded inflorescences from the bushes, this is especially true when using astilbe in landscape design when designing territories.

Fertilizer and dressing

On fertilization under the bushes of astilba during planting has already been mentioned above.

For the full development of the plant is required to carry out regular feeding complex fertilizers. Considering that astilbe can grow in one place without transplanting and dividing rhizomes for more than 5 years, it is necessary to feed plants with nitrogen fertilizers from the beginning of spring. This helps the fast growth of new foliage in overwintered bushes.

During flowering culture is required to fertilize phosphate, and by the end of flowering - potash fertilizers. This will help to increase the time and pomp of flowering, and also stimulates the formation of full-fledged seeds.

Seed propagation

To preserve the decorative and varietal characteristics of the plant, reproduction of perennial seeds is not accepted. Crops grown from seeds often do not meet the stated varietal characteristics:

  • have a modified color
  • sparse floral tassels,
  • low decorativeness
  • short flowering periods.

For seed propagation, you can use only high-quality seeds of varietal selection.

The seeds of the plant are sown on the surface of the moistened soil, without covering up. For accelerated germination, they maintain high humidity (you can cover crops with glass or keep them in a greenhouse). Growing astilba seedlings is reduced to timely watering of seedlings. At this time it is especially dangerous to dry out young plants. They need to be protected from direct sunlight, providing a bright place without access to scorching rays.

Excellent germination results are achieved by performing a preliminary stratification of seeds. This agrotechnical reception consists in placing the seeds in a cold place (from + 4 ° C to -4 ° C) for 3 weeks. Hardened seeds are sown in greenhouses and kept at a temperature of + 20 ° C. Young plants in 2-3 months after sowing can be planted in a permanent place in the open field. The seedlings obtained from stratified seeds are distinguished by excellent survival rate and rapid growth.

Reproduction astilbya division bush

The vegetative breeding method of astilbe (dividing a bush) is the most reliable and customary for gardeners. The mother plant is dug out with care, trying not to damage the tender rhizome. A sharp knife divide the rhizome into parts with 2-3 buds. Sections sprinkled with crushed coal.

Planting material is laid out in the prepared furrow and moisten the ground. Excellent results when planting the delenok are achieved with the use of root stimulants. Care for young plants includes regular watering and loosening the soil.

The planting of the astilba settlement can be carried out in early spring, as early as March. With this method of reproduction, the first flowering of young plants will begin in early autumn.

Kidney division

The reproduction of perennial is carried out in another way, which is considered the fastest - the division of the kidneys. In the spring, with the beginning of the growing season of the plant, kidneys of regeneration are separated with a sharp knife. Cuttings are planted in a hothouse with a wet soil mixed with coarse sand or gravel, after having powdered the cutting sites with ash. With this method of reproduction, a very high survival rate of young plants is noted. The only drawback - getting a full-fledged plant is stretched for almost a year.

Astilba: combination with other plants

Growing astilba in group plantings with other plants is justified. Decorative panicles of plants look great near coniferous plants with their monotonous greens. Such a neighborhood for astilba is very preferable: conifers provide sun protection for bushes.

Perfectly in harmony with astilba bushes with late tulips, irises, hosts, periwinkle. A single astilba landing on a green lawn in the shade is very decorative.

In landscape design, with the design of planting in the shade, astilba bushes fit perfectly. The plant is used for single and group plantings, creating complex landscape solutions for shady and semi-shady places. Care for ornamental plants is absolutely no difficulty and is timely watering.

Please tell me when it is better to transplant astilba in spring or autumn?

Astilbe can be repaired not only at any time of the year, but also divided. And even during flowering. The main thing when transplanting or dividing a bush is to feed it with fertilizers and water it abundantly during the week.
Three years ago I divided a bush into 3 bushes in September. Everything got accustomed, wintered. Today I plan to divide these bushes already. Fell in love with astilba. Good luck and you!

Do you need astilba to cut? If so, when and at what height? Thank.

Astilbe Plant: General Description

Astilbe is a plant that dries the aerial part during the cold season, and only the rhizome remains. The flower stems are straight, reaching a height of 2 meters, depending on the variety. The leaves have long petioles. Sometimes they can be serrated, pinnate, but most often simple, green or reddish-green.

The rhizome of the plant is woody - it can be with a dense or loose structure. Every year, buds appear in the upper part of the roots, and their lower part dies. Since the rhizome increases annually by 3-5 cm, before wintering it is sprinkled with fertile soil. In general, growing a plant involves good care and careful watering.

Astilbe forms inflorescences of small flowers of crimson, white, pink, pale lilac and other shades. They bloom all summer. According to the flowering period, there are early species (June, first half of July), medium (throughout July) and late (mainly bloom in August). The shape of the inflorescences may be different:

Especially spectacular species with drooping inflorescences. After flowering boxes are formed.

Astilbe flower: planting and care

Astilba is propagated by separating the part of the root on which there must be a kidney (vegetative method), as well as seeds. It is easiest to grow a plant by dividing a bush, however, it is seed selection that makes it possible to develop new varieties. When astilba sits down? Planting seeds produced in March. To do this, take a wide tank, which poured a mixture of peat and sand in equal proportions.

A thin layer of snow is laid on top. - it is on it that the seeds are scattered. If there is no snow in your region in winter, you can dial it in the fridge. As the snow melts, it moistens the soil and deepens the seeds into it. After all the snow has gone, the container is placed in a bag and placed in a refrigerator for three weeks.

As soon as shoots appear, the soil is transferred to a well warmed place (temperature 18-22 ° C). Water the flower with extreme caution, otherwise it will die. Water should be poured at the root or injected directly into the ground with a syringe. When a seedling has a pair of leaves, it dives into individual pots - this is the preparatory stage before planting seedlings into the soil.

How to plant astilba in open ground

Planting a flower in open ground is done in late spring - early summer. It is advisable to plant a plant on the north side of the house or among trees and shrubs, where there is more shade. Some varieties are well adapted to the sun - they bloom not so long, but abundantly. Planting near a reservoir or fountain will be a plant only at hand.

The optimal parameters of the soil for the cultivation of astilbe:

  • Type of soil - loamy.
  • Acidity - pH 5.5-6.5.
  • The groundwater level is high.

The flower likes to coexist with hosts. The latter retain soil moisture and do not allow it to overheat in summer.

Before planting in the spring, care must be taken to maintain the site:

  1. Digging the ground.
  2. Remove the root system of weeds.
  3. Enrichment of the plot with compost, crushed peat or dead manure. Two buckets of fertilizer per 1 square meter of bed are taken from the calculation.

Before planting a flower, pits of 30x30 cm are dug. The interval between the pits should also be 30 cm. Half a glass of ash and one tablespoon of complex mineral fertilizer are thrown into each hole. After that, the hole must be carefully watered. Seedlings are planted in such a way that at least 5-6 cm of soil is above the growth buds. The ground should be compacted and ground with ground peat or humus from leaves 5 cm thick.

The main types of astilba

  1. Astilba David - reaches a height of 1.5 m. The flowers are purple or pink, the leaves are wrinkled, with brown veins. It blooms in the second half of summer.
  2. Astilba naked - It is only 12 cm tall, it blooms in the first half of summer, the flowers have a bronze tint.
  3. Chinese astilba - reaches 1 m in height. The flowers are small, pink, white or lilac. Blooms throughout the summer.
  4. Japanese astilba - flowers of white, pink color, collected in rhomboid inflorescences. In height, the plant reaches 70 cm, blooms in July.
  5. Astilba Thunberg - has complex, jagged leaves. It is 80 cm tall. The flowers are white, gathered in fluffy inflorescences. Flowering occurs in the middle - the end of summer.

Growing astilba is not easy. This flower is quite capricious, but if it is given proper care, it will surely please the gardener with beautiful and bright whisk of flowers. Water the plant in a timely manner and follow the rhizome - this guarantees not only healthy shoots and flowers, but also the possibility of further reproduction with the help of vegetation.

Planting and care of astilba (in brief)

  • Landing: May June.
  • Bloom: end of june to august.
  • Lighting: penumbra or shade.
  • The soil: wet loam with a pH of 5.5-6.5.
  • Watering: frequent and plentiful, in the heat - 2 times a day.
  • Hilling: regular.
  • Top dressing: in the spring, when spudding, apply humus, in mid-June - potash fertilizers, before the end of flowering - phosphate fertilizers.
  • Reproduction: seed, vegetative - by dividing the bush, separating the rhizomes from the kidney without digging out the bush.
  • Pests: Dribbling pennies, gall and strawberry nematodes.
  • Diseases: root rot, bacterial spotting, phytoplasma and viral diseases.

Astilba flower - description

Astilbe is a rhizome plant, the aerial part of which dies off for the winter. Astilbe stems are erect, height from 8 cm to 2 m, depending on the type or variety. The leaves are long-petiolate, sometimes simple, sometimes twice or triply pinnate, serrated. The color is dark green or reddish green. Astilbe's rhizome is woody and, depending on the species, loose or dense. Each year, new buds form in the upper part of the rhizome, while the lower part gradually dies off. Annual vertical growth is approximately 3-5 cm, so before winter, fertile soil is added to the exposed rhizome.

  • Astilbe flowers are apical inflorescences of small openwork flowers of white, red, lilac, pink, purple, blooming in June-July-August. Inflorescences are paniculate, rhombic and pyramidal. Very beautiful species with drooping inflorescences. The fruit of astilbe is a box. In terms of flowering astilbe are early (late June-early July), medium (July), and late (August).

    Astilbe Arends (Astilbe x arendsii)

    represented by forty varieties that are the result of crossing the base species - David's astilbe - with other species. These are powerful, spreading, tall bushes (up to 100 cm) of spherical or pyramidal shape with dark green leaves and final inflorescences of white, lilac, red and pink flowers. Blooms longer than other species for 30-40 days from July to August. Cultivated since 1907, but the best varieties were created by G. Arends. Popular varieties are astilba Gloria, Diamond, Weiss Gloria, Rubin, Glut and others. Amethyst, Weiss Gloria and Rubin reach a height of 80 cm, Diamant - 90 cm. But if Diamant, Gluta and Rubin have paniculate inflorescences, then Gloria and Weiss Gloria have diamond-shaped ones.

    Astilbe Chinese (Astilbe chinensis)

    - plant up to 1-1.1 m high, basal leaves large, long-petiolate, stem -small, on short petioles, shiny and openwork. Inflorescences are dense, 30-35 cm long, the flowers are small, usually lilac, but there are varieties with pink and white flowers. It has been cultivated by flower growers since 1859, has undersized forms (var. Pumila hort.) From 15 cm to 25 cm and forms with conical inflorescences var. Taquetii. Astilbe of this species grows well in sunny areas. The most beautiful astilbe Chinese varieties are Astilbe chinensis taquetii “Purpurlanze” of incredible lilac color, pink Astilbe chinensis “Vision in Pink”, Astilbe chinensis (Pumila Hybrida) “Vision in Red” of dark-purple color.

    Japanese astilbe (Astilbe japonica)

    it is presented by plants not high (not higher than 80 cm) and compact, with ornamental leaves, as a rule, shining. Paniculata inflorescences consist of pink or white flowers, blooming earlier than in other species, and even when they wither, they decorate the garden until late autumn. Japanese astilba has been cultivated since 1837, and the first varieties were created by the same G. Arends. Modern varieties have excellent resistance to cold and perfectly take root. Of the most popular ones: Deutschland (Astilbe japonica Deutschland) with white flowers, very beautiful pink Rhineland (Astilbe japonica Rheinland), pale lilac elegant Europe (Astilbe japonica Europe) and finally Astilbe japonica Montgomery with fluffy snowflakes -red or burgundy hue.

    Astilbe simpostifolnaya (Astilbe simplicifolia).

    Dry air and heat are poorly tolerated by wall-laying hybrids (Hybrida) and Thunberg hybrids (Thunbergii Hybrida), and this must be taken into account. Drooping, very showy inflorescences make low plants (20-50 cm) airy. Среди самых изысканных сортов простолистных Praecox Alba с белыми рыхлыми «свечами» соцветий, розоватая Bronze Elegans, получившая свое название за бронзовый оттенок листьев, а также коралловый Straussenfeder высотой 90 см и белый Professor van der Wielen из гибридов Тунберга.

    Выращивание астильбы из семян

    Размножаются астильбы вегетативным путем (делением куста и отделением корневища с почкой) и семенами. And although inexperienced growers prefer vegetative methods, we will tell you how to grow astilba from seeds, because it is the seed method of reproduction that allows you to engage in breeding and get new varieties. Astilbe seeds are sown in March: a mixture of peat and sand (1: 1) is placed in a 15 cm wide tank, and a 1 cm thick layer of snow is placed on top (you can scrape snow in the freezer winter), which is sprinkled over the seeds. Melting snow, moistening the soil, immerses the seeds in it.

    After the snow has melted, place the container in a transparent bag and refrigerate for twenty days (this is called stratification) until germination, and then transfer to a bright warm (18-22 ºC) place. Be careful with watering, otherwise you will ruin the seedlings: water under the root or syringe inject water into the soil. When the seedlings appear 2-3 leaves, they dive into small pots to plant in the ground. When planting astilba from seedlings, we will explain in the next section.

    Astilba - care after landing

    The main feature of astilbe - the growth of rhizomes up and gradual dying off of its lower part. That is, over time, the root system is without power, so the astilba hilling becomes particularly important. Do not allow the soil to dry: timely watering is one of the mandatory rules, which includes the care of astilba. In addition, mulching will allow you not only to protect the root system from overheating, but also to keep soil moisture longer, as well as relieve weeds and often need to loosen the soil. Astilbe needs medium to high water depending on the species and variety, but all species need regular and abundant watering during the period of formation of inflorescences. In a strong drought water astilba twice a day - early in the morning and in the evening.

    Astilba can grow for 5-7 years without a transplant, but if you carefully care for it and apply fertilizer in time, then its life span in the same area can last up to twenty years. Astilba feeds in the spring with nitrogen fertilizers (application of humus during hilling), in mid-June - potash fertilizers (half a liter per bush of solution of 2 tablespoons of potash nitrate per 10 liters of water), and before the end of flowering - phosphorous (20 g of superphosphate per bush). After feeding, the soil is loosened and mulched again.

    Astilbe, like many other introduced plants, has left its specific “enemies” in the places of origin. In our latitudes, it is sometimes struck by a slobbering pennitsa and two nematodes - strawberry and gallic. Pennitsa settles in the axils of the leaves and forms frothy salivary-like discharges, inside of which the Tsikadki larvae live. The more pennits, the more frowning leaves, becoming covered with yellow spots. As a result, the plant fades partially or completely. It is possible to get rid of a slobbery pennitsa by treating plants with konfidor, rohor, karbofos or aktar.

    Strawberry Nematode - leaf pest, it is parasitic on the kidneys, leaves and flowers, from which they are deformed and covered with yellow or brown necrotic spots. Plant growth slows down. Gallic nematode affects the roots, forming on them small growths (galls), inside of which there are nematodes. Apparently visible galls become in the second term of the growing season. Infected plants develop poorly and bloom, sometimes even die. It is necessary in time to reject plants with obvious signs of infection and remove them. In addition, watch for the appearance of weeds in the first half of the growing season and immediately remove them. In the second half, the roots of astilba, growing, drown out the weeds, and weeding is no longer necessary. Plants on the site treat fitoherm.

    Astilba after flowering

    When the astilba ottsvetet and flower stalks begin to dry, do not rush to cut them, because even in a semi-dry form, the spectacular astilba inflorescences will decorate your garden. But at the end of the season, when you have to restore order in the flower garden before winter dormancy, the astilba stalks need to be cut flush with the ground, and the site will be mulched. Especially if before that you planted astilba by dividing the rhizomes. This is done in order to rejuvenate astilba, because when the root is woody, it will be difficult to separate it. Therefore, in early autumn, the rhizomes are divided so that each delenka has a growth bud, then the next year, as a rule, the transplanted astilbe will bloom.

    It is only necessary to mulch the area, and it would be good to shed some spruce branches on freshly replanted rhizomes to protect new plants from the winter frost and to be sure that the astilbe will not die in the spring from a sharp temperature drop.

    Astilba - description, appearance and features

    Astilba blooms most actively about a month, starting from the first days of summer, the flowering process itself continues until August. Decorations are distinguished not only by flowers, but also by the long-peeled dark green leaves of astilbe growing on erect stems. The color spectrum of lush panicle is rich in a variety of shades: white, cream, pink, lilac, red. The delicate aroma of astilba is a bit like the fragrance of a bird cherry.

    The birthplace of the flower is Japan and Asia, the number of varieties reaches 200 varieties, there are dwarf (“Liliput”), tall varieties of astilbe (Arens hybrids). Observance of simple agrotechnical rules even for a novice gardener can grow a lush, eye-catching plant — that is why this culture is so loved by many. For ideal growth, development astilbe need a shadow, but not too strong. The so-called "lace" shadow from the crowns of the trees - what we need.

    Astilba will make every corner of the garden cozy

    With the onset of cold weather, the above-ground part of the astilbe dies off, and the overwintered root with the onset of spring gives new shoots. A remarkable feature of astilbe - its rhizomes are growing from above. Thus, on the upper part of the root system, kidneys are tied, which are exposed, therefore they require annual filling of the soil. Every year their size increases, forming new roots, with the lower part gradually dying off. Flowers-panicle reach from 10 to 50 cm in length, when the flowering period ends, in their place are boxes with seeds inside.

    For comfortable cultivation, it is preferable to give your choice to tall varieties - those that grow up to 50-80 cm. They are more resilient, tolerate climatic changes, temperature changes.

    As mentioned above, there are many different species of this plant, but the majority of gardeners liked the Japanese astilbe. This variety is also called astilba Montgomery - a hybrid bred by German breeder Georg Arends in 1837.

    Astilba Montgomery

    Arends hybrids are the brightest, beautiful, unpretentious, they grow well on any soil, resistant to cold, bloom for a long time (about 40 days). In addition to "Montgomery", Gloria, Deutschland, Europe, Rheinland are popular with gardeners.

    Japanese astilbe grows up to 80 cm high, has ornamental leaves, its flowers bloom early. After the flowers ottsvetut, they do not lose their decorative qualities, do not spoil the overall picture of the garden with their appearance, are often used to compose dry bouquets.

    Where to plant astilba

    The most important requirement when planting astilba is to choose a comfortable place for it, preferably in the northern part of the site. The planting process is best to start during the beginning of May / early June. Choose shady places or a territory near the pool, a reservoir (if you have one), keep in mind that only some varieties of astilbe prefer sunny areas. As mentioned above, this plant can grow on almost any soil, but especially it loves loam, fertile soil, soil saturated with potassium-phosphorus additives.

    If there is an increased acidity on the ground, it is recommended to add some wood ash before planting to lower the pH level, also dolomite flour can be used for these purposes.

    When planting, be sure to take into account the proximity of plants, for example, growing nearby hosts will not only be in harmony with the leaves or flowers of astilbe, but will protect it from overheating in hot summer. You also need to pay attention to the variety, the timing of its flowering. Early, late varieties will be equally comfortable in a sunny, shady place. Those varieties that bloom in the midst of summer, you need to pick up only shaded places. High groundwater flow, as well as periodic water stagnation at the site is extremely undesirable for astilbe. To prevent the root system from getting wet, you will need to arrange drainage or plant the plants on high ground.

    Make sure that the planting material (astilba roots) does not have rotten or dead skin fragments. The roots should not be too wet or too dry.

    Astilba - care and landing

    Place on the site should be prepared before planting: dig, root out the roots of shrubs, remove weeds, fertilize the land with manure or add peat (approximately 2 buckets per 1 square meter). The holes for astilba bushes should be about 30 cm deep. It is recommended to pour some ash (handful), mineral dressing into the depths of them, then generously pour water. Start landing. Make sure that at least 5 cm of soil is poured over the roots of the plant, which should be carefully compacted and then covered with a layer of mulch (also 5 cm). For mulching suitable peat or humus.

    Astilbe can be propagated by seed or vegetative methods, in the second case, fragments of rhizomes or buds are used. After the plant blooms, seeds ripen in boxes, they are sown in early March, but before that they are “hardened” with cold. To do this, take a suitable container, pour a mixture of peat and sand (equal proportions), sprinkle seeds on top, put a 2 cm layer of snow on top of them (you can use snow from the freezer).

    The snow will melt naturally, deepening the seeds inside the soil. After the snow has melted, cover the container with glass or plastic wrap, and then place in the refrigerator for 3 weeks. For these purposes, perfectly suited lower compartment, where they usually store vegetables. During this period, already hardened shoots will sprout, which will eventually turn into strong plants that are not afraid of cold and frost.

    After the appearance of sprouts, move the container to the lighted place, where the air temperature is not below + 20 ° C. Water the shoots should be very careful, for this it is better to use a syringe to direct the stream of water to the spine. After the appearance of the first 3 full leaves, small astilbe can be seated in individual pots. It should be borne in mind that varietal cultures do not propagate by seed — hybrids do not retain their individual traits.

    Rhizome division is the easiest, most effective way of reproduction. To do this, a full-fledged plant should be dug, removed from the soil along with the roots, with an earthy clod. Then gently shake the ground, expose the root system, take a knife, divide the root into fragments, with at least 4 buds on each piece. After that, you need to plant the roots at a distance of 25-30 cm from each other, water daily (not too plentiful).

    Reproduction by the kidneys gives the fastest results. It is best to select the seed in the spring, when the growth of new shoots is activated. The kidneys are carefully cut together with a piece of rhizome, the place of the cut is sprinkled with ashes or crushed mortar with a tablet of activated charcoal. After that, they take a container, fill it with a mixture of peat and gravel (3 parts of peat, 1 part of gravel), and then dig in the kidneys, cover it with glass or plastic film. When the plant grows, it will get stronger, it can be planted on the plot using the method described above.

    Aesthetic, undemanding astilbe, planting and care in the open field are not difficult, the main thing to remember about the unusual features of its root system, to ensure that the roots were covered with earth. Provide astilbe regular watering (according to the grade). Mulching is desirable. Both overheating and waterlogging are equally harmful to all plants, and the mulch layer will help keep the roots healthy. Remove weeds, water more often during flower formation, apply top dressings according to the season: in the spring - nitrogen, in the middle of summer - potash, in the end of summer - phosphorus. Replace astilba should be every 8-10 years. With the right approach to business, this plant will transform your summer cottage, give positive emotions, bright colors of summer.
