Astra planting and care in the open field


Asters - diverse and beautiful flowers that delight their bloom in late summer, when most of the plants have faded. One-year or perennial asters will become a real decoration of your garden, these are unpretentious flowers, it is easy to care for them.

Consider the secrets of growing asters from sowing seeds to flowering, the most popular varieties of perennial and annual plants, proper care for asters in the process of growing, how to propagate asters, what to do when asters have bloomed.

Perennial aster species

Asters perennial, in terms of flowering, are divided into two large groups - early flowering and autumn flowering.

Perennial asters represented by such species: Italian aster, bush, alpine, nobel Belgian, new England.

Astra is a new Belgian - tall bush up to one and a half meters, not very strong, can fall apart. The beginning of flowering occurs at the end of August and may continue until the first snow.

Astra New England - bushes grow to 1.5 meters in height, flat and slender, not requiring garters. The inflorescences are semi-double, large with various colors: white, pink, purple, violet, the middle reddish or yellow. The beginning of flowering falls at the beginning of September and continues until the first frost.

Alpine aster - Low-growing plants up to 30 cm in height with single inflorescences. The earliest varieties begin flowering in May, therefore, it belongs to the early flowering species.

Astra is shrub - bushes up to 60 cm high with strongly leafy stems. From autumn asters begins to bloom first.

Astra Italian - early-flowering aster species with large inflorescences up to 5 cm. The height of the bushes is up to 70 cm, flowering begins in June-July. Very suitable for rose gardens and stony gardens.

Cultivation and care - perennial asters

Perennial asters are grown on sunny, well-humidified areas of the garden. Plants are able to grow in one place for 6 years. Care for perennial asters is easy. Basic care is soil loosening and treatment against diseases: powdery mildew and gray rot.

Reproduction of perennial asters produced in the spring, green cuttings. Emerging in spring or early summer, young shoots are used for breeding. They quickly germinate and root, resulting in strong and strong bushes. Reproduction of perennial asters by dividing rhizomes is also possible. Seeds to propagate perennial asters is difficult and unproductive.

Annual aster species

There are over 4000 varieties of annual asters. Often shaggy, large and fluffy asters with one flower on a long stem, with lots of colors and shades.

The classification of one-year asters is very diverse, briefly acquainted with her.

By flowering time: early (bloom in July), medium (bloom in early August), late (bloom from mid-August).

The height of the bushes: dwarf to 25 cm, undersized to 35 cm, medium tall to 60 cm, tall to 80 cm, gigantic over 80 cm.

According to the purpose of cultivation: casing - long-flowering, a lot of inflorescences, cut-off - lush lights with long stems, cut for bouquets, universal - suitable for garden decoration, and for cutting into a bouquet.

According to the structure of the inflorescences: reed, transitional, tubular.

Reed asters

Magnificent, spherical, shaggy flower. By reed asters include such species on the principle of the structure of the inflorescences: curly, spherical, tiled, hemispherical, needle.

Curly asters, popular varieties for cutting - Hohenzollern, Queen of the market, Ostrich feather, California giant. Universal varieties - Chrysanthemum, Early miracle, Comet.

Needle asters, popular varieties are Krallin, Riviera, Star, Record, Exotica.

Transient asters

The inflorescences consist of 1-2 rows of reed flowers, tubular flowers fill the middle. Here, such species are distinguished according to the principle of the structure of the inflorescences: simple, semi-double, and crown.

Have simple asters the middle of the inflorescence consists of yellow small tubules, which is framed by 1-2 rows of straight reed petals. Popular varieties are Margarita, Sonnenstein, Waldersee, Apollo, Edelweiss.

Semi-double asters with bulky flowers in which reed petals stick out in different directions, but the middle is clearly visible. Grades - Madeleine, Anemonovidnaya, Mignon, Rosette, Anmouth, Victoria Baum.

Coronary asters resemble pompons, fluffy with a barely visible core. Varieties - Fantasy, Princess, Aurora, Laplat, Ambria, Pomponnaya, Princess Bouquet.

Growing asters from seeds

Annual aster is grown mainly from seedlings by seedlings and seedless ways.

Asters grown in a seedless way bloom later. Early varieties sown in the ground in mid-March, then asters bloom in July. Later varieties are sown in late April, early May, the air temperature should not be below +10 degrees.

Sowing is carried out in small grooves with a depth of 4 cm, plentifully watered and covered with earth. If dry weather sets in, the crops are mulched or covered with covering material until the first shoots appear. After the appearance of the first two true leaves, it is necessary to thin the plants, leaving a distance of 10-15 cm between them. Transplant seedlings to another place.

When to sow seeds

By the time of flowering aster is divided:

Early - bloom 90 days after planting, medium early - 110 days after landing (in August), late - in 120-130 days (end of August, beginning of September).

Before starting sowing asters do simple calculations. Also, seeds are sown in late autumn in frozen ground. In spring, the emerged shoots thin out. The shelf life of seeds for 2 years, after which germination is halved.

Growing asters by seedling

A more reliable way to grow asters, although it takes more time and care. Sowing seeds for seedlings produced in early April, or May, it all depends on the variety. Before sowing, 7 days before the start, it is necessary to wrap the seeds in a cloth and soak in a weak solution of potassium permanganate for 10-12 hours. Then remove excess moisture by squeezing the fabric. Place the seeds for germination in a warm place.

For growing seedlings fit pots or boxes. The soil should be fertile and light. Make shallow grooves in the ground, sow the seeds that have spiked and sprinkle with a layer of sand in 0.5 cm. Spread the crops on top with a weak solution of potassium permanganate, through a fine sieve. Cover aster crops with film or glass, put in a warm place with a temperature (20-22 degrees).

After 3-5 days, shoots will appear, transfer the seedlings to a cooler place with a temperature of 16 degrees. With the appearance of 3-4 leaves on the shoots, they sow the seedlings according to the 4x4 cm scheme in small pots or large boxes. Dive plants watered moderately.

Planting seedlings in open ground

Feed the seedlings with complex fertilizers, one week after the pick. Hardening of the seedlings, bringing to the time in the open air. When the plants were formed up to 10 cm high, with 6 leaves - they are ready for planting in the ground. The best landing time is the end of April - the middle of May.

Seedlings of asters can be planted in mid-May, the plants are not afraid to freeze to -4 degrees. Planting seedlings produce in the evening.

Astra prefers sunny areas with good drainage. It grows best on fertile and light neutral soils. Prepare a place for planting aster seedlings in the fall: dig a plot deep with compost or humus (3 kg per 1 m 2), in the spring dig a plot with 20 g of superphosphate, 15 g of ammonium sulphate and potassium salt per 1 m 2. If the soil is not depleted at the intended planting site, fertilizer can be avoided.

Before planting, the area must be weeded away from the weeds, leveled and pierced by 4-6 cm. Make not deep grooves, spill them with water and plant the plants with a distance of 20 cm from each other (depends on the variety). There is a distance of 50 cm between the rows. Sprinkle the seedlings with dry soil and irrigate after 2 days. After 2 weeks, feed the plants with nitrogen fertilizers.

Care for aster

Asters unpretentious flowers, do not require much time and effort. The main thing in care is the obligatory loosening of the soil after each rain to a depth of 4-6 cm. Weed weeds. Before branching begins, the stem should be earthed at 6-8 cm in height, this will accelerate root growth. Remove dried flowers in a timely manner.

The lack and excess of moisture harms asters. With the onset of sultry heat, water less frequently, but copiously (up to 30 liters per 1 m 2), after which you must loosen the soil.

Fertilizing fertilizer for the entire growing season should be three.

First 2 weeks after transplanting seedlings into the ground (10 g of potassium sulfate, 50 g of superphosphate, 20 g of ammonium nitrate are applied per 1 m 2 of the site). Second feeding carried out with the appearance of buds on plants (50 g of superphosphate and potassium sulfate per 1 m 2 plot). Third dressing held at the very beginning of flowering, the same composition as the second.

Diseases of asters

The most common disease of asters is fusarium. Manifested in adult plants: aster fades, turns yellow.

For the prevention of fusarium disease, it is necessary to conduct crop rotation and crop rotation. Alternate planting asters with other plants, it should not fall on the same place earlier than after 5 years.

Do not land the aster on the areas where it was growing solanaceous (tomato, potato), there is a risk of getting fusarium. If the plants are sick, they must be removed and burned to prevent the spread of the disease.

Blackleg affects asters - a fungal disease that leads to blackening of the seedling and rotting of the base of the stem and root collar. Remove diseased plants from the site, disinfect the soil with a 1% solution of potassium permanganate.

Rust - Another disease that manifests itself from the underside of the leaves, they fade and dry. Landing asters spend as far as possible from conifers, they spread rust spores. Spray diseased plants with 1% solution of Bordeaux liquid, this solution is also suitable for prophylaxis.

Mealy dew - A disease with which foundation is doing well.

Aster pests

The main pests include meadow bug, plowed slug, spider mite, scoop, kidney aphid, slobbering, ordinary earwig.

To prevent the appearance of pests in the fall, burn the annual and dying off the shoots of perennial plants.

Conduct a struggle with folk and chemical means.

Corn slugs destroy mechanically (collected) or treated with the preparation Metaldehyde.

Pests like spider mite, scoop, meadow bug and slobbering destroy phosphamide solutions, karbofos, pyrethrum. Upon detection earwig ordinary Spray the plants with a foundation.

What to do when asters bloom

After flowering, annual asters must be dug out and burned, thereby destroying fungi, viruses and pests. If you have picked the seeds of the varieties you like, you can sow them into the soil after the first frost, but in a different area. Seeds are sown in the grooves and covered with humus or peat.

The collection of seeds is carried out as follows: wait until the inflorescence withers, its center darkens, a white fluff appears. Tear off the inflorescence and place in a paper bag, it will dry out there, do not forget to sign varieties. It is better to sow last year’s seeds in the ground, because after 2 years they lose their germination.

Perennial asters are frost-resistant, but some varieties whose young plants are desirable to cover with dry leaves or peat for the winter. If the stems are dry, it is better to cut them before shelter. With the arrival of spring shelter is removed, and asters quickly go to growth.

Here you have learned the basic types and rules of care for perennial and one-year asters. Let asters delight you with their bloom every fall!

Aster seeds

To grow asters, purchase seeds not only from foreign companies. Domestic seeds are more reliable (for example, they are more resistant to Fusarium) and are designed for our climatic conditions.

Do not buy seeds in the first store. Some unscrupulous sellers put expired or left seed for sale. Sometimes purchased in large quantities, they do not have time to be sold in the first year or two. It is hardly possible to achieve good germination from such seed.

When purchasing seed bags, check the expiration date. If the sprouts do not appear, try to buy seed in another store and plant again. The beautiful appearance of aster flowers depends on planting and care.

Rassadny way for asters

Planted annual asters in two ways. The first, seedling, is more laborious, but the inflorescences appear earlier by several weeks. If you want to have a magnificent bouquet of asters in the garden by September 1, choose the first method. It is also suitable for obtaining seeds.

Seeds deepen to 0.5-1 cm. Planting is recommended to be watered with a weak solution of potassium permanganate. Before the appearance of the first shoots, containers with asters are kept under a transparent cap in the shade, and then they are opened and set on a permanently bright place.

To conduct or not to conduct a dive, each gardener decides for himself. Some prefer not to disturb young plants, not to transplant them separately. Moreover, the seedlings grow beautifully in a large group. And when planting in the ground just separate the plants from each other, gently releasing the roots.

Asters seedlings care includes weekly fertilizing with complex fertilizer. Seedlings are transported to the open ground in May, when they have a strong stalk up to 10 cm high and several strong leaves. It is better to do transplanting in the evening so that the young shoots get accustomed to the new place a little overnight.

Compost or humus is introduced into the soil under the seedlings; wood ash and dolomite flour can be added. Saplings well moisturize, and then rooted in pre-watered grooves, keeping a distance of 20-30 cm between them. Sprinkle with dry land.

Choosing a place

Asters like sunny areas of gardens, grow well in light partial shade. They prefer light fertile soils (neutral or slightly alkaline).

Flower beds are prepared from autumn. For what purpose the selected site is dug up to the depth of a bayonet spade with the addition of humus or compost to choose from (up to 4 kg per m²). If the soil is depleted, then by 1 square. m in the spring digging, you can add superphosphate - up to 40 g, ammonium sulphate and potassium salt - 20-30 g each.


Experienced gardeners know that in order to get a good harvest, lush flowering, crops need to be periodically transplanted to other places. In addition, it is worth carefully selecting plots for those plants that do not tolerate certain predecessors. It is not advisable to plant asters on the place where tomatoes and potatoes have already fruited. A flower bed of asters will grow badly after tulips, carnations, gladioli.

Before planting asters, seeds form small grooves. Why put in them the seeds, sprinkled on top of a layer of earth one centimeter thick. Water the seedlings with ordinary water, or diluted with potassium permanganate to a slightly pink color.

After planting, in order to avoid rapid drying of the soil, asters should be mulched, for which peat or a special film is used. Use the shelter until the first shoots hatch.

Young asters thin out when the first two true leaves appear. Between colors leave a distance of 15-20 centimeters. Some varieties require more space. It depends on the height of the flower.

Care of asters

Care of asters includes a full range of measures: watering, feeding, loosening, disease prevention and treatment in case of diseases.

For the proper formation of the flower need a good watering. Do not allow prolonged drying of the soil or strong waterlogging of the site with water. For hot weather, abundant but rare watering at the rate of 30 liters per square meter is preferable. Do not forget after him to loosen the beds.

Care in the open field for asters requires mandatory dressings. It is not allowed to use fresh manure, which leads to fusarium. Use of mineral fertilizers will be safer.

During the season, conduct several dressings:

  1. Fifteen days after the rooting of the seedlings or when the saplings reach a height of 10-15 cm, any complex fertilizer can be applied.
  2. During the laying of inflorescences, it is better to use either ammonium nitrate or a complex fertilizer with a nitrogen content.
  3. When nominating the buds, it is better to take full mineral fertilizer.
  4. For the flowering period, suitable mixtures with phosphorus and potassium or wood ash.

Periodically need to water the plants on top of a solution of potassium permanganate slightly pink. This allows you to achieve lush and beautiful inflorescences. But they only moisten the stem and the leaves, you do not need to pour water on the flowers themselves.

After planting, an aster flower may bloom almost until frost occurs. Different varieties form inflorescences from late July to early September.

Blooming time is different:

  1. early varieties require 90 days after germination,
  2. for medium - 110 days,
  3. for late - 130 days.

Астры украшают сады до первых осенних заморозков. Однолетние сорта прекрасно подходят для формирования букетов. В срезанном виде они могут сохранять прекрасный свежий вид до двух недель.

Asters normally relate to transplantation, quickly recovering even after changing permanent place of growth. Gently digging a flower with an earthy clod, it can be transferred to another site or planted in a container, decorating the yard or balcony. So you can plant new plants instead of dead or faded, or you can simply create a new look of a flower garden.

Seed collection

After flowering asters burn. It is done in order to destroy harmful insects and various viruses. Gather seeds after withering and browning flowers. Appearing in the center of the fluff is cut and laid out in paper bags. Seed collection involved in dry weather. Because wet seeds will require drying.

Seeds are planted before winter, but in another area. They are laid along the grooves, and the top is covered with dry humus or peat. You can sow seeds in December and January. Gardeners argue that such planting is even safer, since the material is not afraid of temperature fluctuations. After the snow melts, to accelerate germination, the area is covered with a film.

Insect pests

You can fight insect pests with the help of folk remedies or toxic chemicals. For example, the plowed slug can be simply assembled by hand or the drug metaldehyde can be used to destroy it. Plants with spider mites, meadow bugs, shovel sprayed karbofosom, fosfomycin. Fundazol used to combat earwig ordinary.

To prevent the occurrence of insect pests, there are a number of preventive measures.

This includes:

  • digging the land for the winter,
  • destruction of dead and decayed plants,
  • the right choice of varieties
  • soil quality improvement
  • respecting distances when planting plants.

Asters look great on a bed with other flowers. You can pick up a certain combination of shades and heights, getting a cascading flower garden. Asters are unpretentious. And sowing these flowers for the first time on their own plot, you can fall in love with them for life.

All species are divided into two large groups:

  • Annual asters - a group of single-herbaceous plants with large inflorescences, which are often grown for cutting.
  • Perennial - plants of bush forms with strongly spinning shoots.

Numerous subgroup, including such prominent representatives as:

  • Alpine aster - a perennial aster with a height of 15 to 30 cm, which bloom is noted in late spring. Popular varieties: Wargrave, Glory.
  • Italian aster - chamomile aster with large corymbose inflorescences, which are noted in the first half of summer. Plant height can reach 70 cm. Rosea, Rudolf Goeth are distinguished from varieties.
  • Astra Bessarabian is a branchy medium-length shrub up to 75 cm in height, the shoots of which are topped with lilac-tingled buds.

Subgroup, distinguished by a variety of species composition:

  • Astra is a shrub - the earliest flower of the subgroup, the height of leafy stems of which does not exceed 60 cm. The most famous varieties are: “Niobey”, “Blue Bird”.
  • Astra Novobelgiyskaya - a widespread species in the gardens. It is represented by both tall and dwarf varieties, among which dwarf Snowsprite, Jenny, mid-growth Royal Velvet, Winston S. Churchill, tall Dusty Rose, Desert Blue deserve special attention.
  • Astra New England - another popular variety is represented by tall plants, up to 160 cm high with a large number of small inflorescences. Common varieties: Browmann, Constance.

There are several classifications based on various parameters:

  • in terms of flowering (early, medium, late),
  • in height (dwarf, short, medium tall, gigantic),
  • on the purpose of cultivation (cut, casing, universal),
  • on the structure of the inflorescences (tubular, transitional, reed).

Spherical large-flowered aster “American beauty”, needle “Record” with medium inflorescences, curly variety “Ostrich feather” and semi-terry “Rosette” stand out among a huge variety of varieties.

Assesless landing

Sowing of early varieties is carried out at the beginning or in the middle of March, and later ones - in the second half of spring, when the stable weather will be stable above 10 ° C.

  1. 4 cm deep grooves are prepared.
  2. Seeds are placed in the grooves and flooded with water.
  3. With the arrival of dry weather, crops are mulched.
  4. After the formation of two pairs of true leaflets in the seedlings, the rows are thinned out so that there is an interval of 15 cm between the seedlings.

Sowing is carried out in the first half of spring as follows:

  1. 7 days before sowing, the seed, wrapped in cloth, is soaked in manganese solution for 10 hours.
  2. After the allotted time, the fabric is squeezed out and, together with the seeds, is placed in cellophane for germination.
  3. Boxes for seedlings are filled with a light substrate, which is watered with a fungicidal solution for disinfection.
  4. Seeds are buried to a depth of 5 mm.
  5. The container is covered with glass, after which it moves to a warm place.
  6. When seedlings appear, the seedlings are taken out in a room with a temperature of 16 ° C.
  7. After the seedlings have two pairs of true leaves, they are picked with shortening of the roots.

Weeding and hilling

To accelerate the growth of root mass before the beginning of branching of aster stems, it is recommended to roll up to a height of up to 8 cm. An important care measure is cleaning the soil from weeds.

For lush flowering plants need additional nutrition, which is carried out at least three times per season:

  • 10 days after the seedlings are planted in the open ground, top dressing is carried out using complex mineral fertilizers, which include nitrogen.
  • Phosphate-potassium fertilizers are introduced into the phase of budding under the plants.
  • At the beginning of flowering, asters are fed a third time as fertilizers with a high content of potassium and phosphorus.

Asters have faded - what to do?

If the site grew annual varieties, then all plant residues should be removed and burned, after collecting the seeds from the varieties you like. Sowing material can be sown before winter, but in another area that is not infected with specialized harmful organisms. Perennial representatives of the culture are winter-hardy and can grow in one place up to 5 years. Upon reaching the maximum age after flowering is to dig up the bushes and split. Delenki spread to other sites.

Diseases, pests and care during this period

Gentle and graceful flower in violation of the agrotechnical cultivation may be affected by both diseases and pests. Among the diseases, the greatest danger is represented by fusarium, which is not amenable to treatment, as well as rust, powdery mildew and black leg, developing in the seedling phase. Of the pests on asters, there are meadow bug, slobbering pennits, arable slug, earwig, spider mite, kidney aphid and scoop, which should be controlled with insecticides of systemic action.

Use in landscape design

The choice of art object, for the design of which asters will be used, depends on the size of the variety. For example, Astra heather ground cover is perfect for decorating an Alpine slide, and medium-grown Italian asters will harmonize with decorative yarrow in a mixborder. Flowers will fit into any floral arrangement, if you choose the right shape of the plant.

Thus, Astra is a beautiful flower with high decorative qualities, which with all its grace remains undemanding in the care.

Planting a plant

Planting of asters in the open field is made after the selection of a suitable site. Permanent place is to select, taking into account the light-loving plants. You should also prepare a good drainage for flowers. Best of all, Astra feels in the place where the calendula was growing before.

If planting is done by seedlings, then first you need to sow seeds in the open ground. Sprouts sprout in 5-7 days. After the appearance of 3-5 developed sheets on them, picks and thinning are made. Next, landing asters on a permanent place.

The most favorable time for disembarking young asters is the middle of spring. Already in April, the air temperature is suitable. Planting seedlings produced in the evening.

In order to prepare the soil, it is necessary to dig a lot of land in autumn, in which asters are planted, with the introduction of humus or compost into the soil (2 kg / m 2). After the snow disappears, the site is dug up again. If the land is poor, then 30 g / m 2 of superphosphate and 20 g / m2 of potassium salts must be added to it.

Important! The first watering is done not during planting, but after 2-3 days.

Plant Care

Astra is not a very demanding culture, so taking care of it does not take much time and effort. The main thing - in time to loosen the ground and remove weeds. This procedure must be carried out after watering or rain has passed.

For asters, watering is important. But here it is necessary to take into account that they tolerate an excess of moisture as painfully as a deficiency. In hot weather, it is better to water asters that grow in the open field, less often, but more abundantly (30 l / m 2). If watering is not done on time, the inflorescences may lose their decorative appearance.

Care also includes the timely removal of dried flowers and leaves. This should be done in the morning, in order for the plant to have time to tighten the wound. If the dead or diseased areas of the flower are not removed, the plant will waste nutrients to restore them.

Fertilizer and aster feeding

An important step in the cultivation of all varieties of asters is fertilizing. During the whole season it is necessary to apply fertilizer at least three times.

10 days after landing:

  • ammonium nitrate 20 g / m 2,
  • potassium sulfate 10 g / m 2
  • superphosphate 50 g / m 2.

When the first bud appears:

  • potassium sulfate 10 g / m 2
  • superphosphate 50 g / m 2.

At the beginning of flowering:

  • potassium sulfate 10 g / m 2
    superphosphate 35 g / m 2.

Timely fertilization of the soil will allow the plant to please you with a much larger number of new blossoms.

Plant propagation

Cultivation of asters involves its subsequent reproduction, which is performed using seeds and dividing the bush. Planting seeds of annual asters in open ground is done in the spring no later than 2-3 years after they are harvested. A perennial sown at the end of the season in the fall, immediately after collecting the material.

Also, perennial asters are bred by the vegetative method (by dividing the bush). If the plant is divided in spring, then in autumn you can observe the flowering of its separated part. Astra is very easy to tolerate division. Vegetative propagation is carried out when the detachable part has 4 new shoots, one bud and several roots.

From May to August, asters can be propagated by the cutting method. As the planting material choose apical cuttings (6 cm). Reproduction is performed with the planting of the material in the prepared mixture of turf, peat and sand. A month later, the cuttings rooted completely.

Diseases and pests

Asters, like any other plants, are susceptible to attacks of pests and disease-causing organisms. Also, this culture is affected by viral diseases. Signs of disease appear on the stems, leaves and inflorescences of the plant. The growth of the affected specimen slows down, the flowers deform and may die.

To avoid losses among plantations, it is necessary to use quality planting material and choose virus-resistant varieties. Also, prevention can be the right care for the culture.

The most dangerous for asters are insectstransmitting viral infections.

Passed slug. It feeds on the green part of the plant. Eats leaves, and sometimes buds. When a pest is affected by this pest, oblong holes are formed on the leaves, mucous secretions are observed. Reproduction slug occurs in conditions of high humidity.

You can fight it with the destruction of weeds and conducting autumn plowing. Calcification of lime along the boundaries of the plot will also help.

Earwig. Adults are especially dangerous. The attack by these insects occurs in the second half of June. They feed on buds, buds and leaves of asters.

The main method of struggle is pollinating plants with a foundation.

Astro blizzard. This is a small butterfly (20 mm in wingspan). Both adult individuals and caterpillars are dangerous. The attack of these insects often occurs during the flowering period. Adults lay eggs in the inflorescence, the caterpillars first feed on pollen, and then they eat the whole flower.

To avoid such attacks, it is necessary to prevent the landing of asters in the vicinity of the sunflower. It is also necessary to treat the soil before planting the basudin, since the caterpillar pupates and winters directly in the soil.

Spider mite A small insect of yellow color, located on the bottom of the leaf and sucks the juice out of it. Damaged leaves dry and fall. Active reproduction of the tick occurs in dry weather.

Spraying the plant with a solution of 0.2% carbaphos or onion extract will help to cope with the pest. For the preparation of which, it is necessary to drop 100 g of warm onions into a 3-liter jar of water, cork and leave for 8 hours. Strain the liquid and add another 7 liters of water. To improve the effect, add 45 g of liquid soap.

Among the most dangerous diseases of asters are:

Fusarium Caused by the fungus Fusarium, which is in the soil in the form of spores. The fungus enters in the process of absorption by the roots of useful substances and clogs the entire vascular system of the plant. It appears dark stripes on the stem and leaf wilting on one side. You can also see a pinkish bloom on the basal area - this is the mycelium of Fusarium. It spreads with increasing humidity.

You can fight the disease by applying lime and dressing the planting material in the foundation solution. Steaming soil will also help prevent the formation of fungus.

Jaundice asters A viral disease that can infect a plant with cicada and aphid. Manifested by clarification of the leaf plate along the veins. With the progression of the disease, growth suppression is observed. The buds turn green and stop growing.

To prevent the development of the disease, it is necessary to destroy the carriers of the virus. Affected plants are removed and burned. With aphids fight broth yarrow, they sprayed every bush of asters growing in open ground.

Blackleg. Disease caused by fungus. Young plants are affected. Manifested by the blackening of the neck of the root and base of the stem. The pathogen is actively developing in acidic soil.

For the prevention of the disease, an early picking of young asters seedlings and sanding of the root area with sand is performed. When a disease is detected, the affected plants are removed, and the soil is disinfected.

Astra: combination with other plants

Asters are beautiful in their own right and next to other plants. A combination of different types of asters in a flower bed will bring a variety of bright colors to the garden. The plant is wonderfully combined with phlox and dahlia. Alpine aster with blue flowers can be combined with bearded irises.

Astra Echinacea will help to create a good composition, such a duet will look especially attractive during autumn leaf fall. Also very good look near the high asters with inflorescences of warm shades of perennial sunflower flowers. The combination of plants matched to each other or in contrasting colors is most attractive for any garden.

Astra in landscape design

Cultivation of asters using in landscape design implies special care for plants. They make the appropriate formation and decoration of additional materials.

In landscape design mainly perennial asters of small stature are used. The favorite of designers is the Alpine aster. Its small size and abundant flowering can not leave indifferent a single person.

Alpine aster in combination with natural stone looks very advantageous. It emphasizes the severity of the shape of the stones, and the delicate shades of the flower stand out particularly well against a gray or beige background.

Landing features

It is best to start preparing the soil for planting this type of flower in the autumn. It is worth knowing that flowers of large size are only in those plants that received a sufficient amount of essential nutrients from the soil and water. When digging the soil do not forget to make humus.

Most often, a plant of this species is grown from seed in a seedless or seedling manner.

Seedless way

Seeding is done, as a rule, in the first weeks of spring. Для этого делаются небольшие бороздки маленькой глубины. После того как почва будет хорошенько пролита, ее поверхность следует накрыть пленкой, которая убирается, когда астры начнут всходить. Также производится и посев семян в зиму. Делают это в заранее подготовленные бороздки с наступлением стойкого холода (грунт должен быть замерзшим).

After asters grow up and they will have 3 true leaves, they need to be thinned out. To do this, remove the extra seedlings so that between the remaining asters there is a distance of 15 to 20 centimeters. By the way, if extra asters are carefully dug, they can be transplanted to another place.

How to care

Such flowers are quite unpretentious and there are no particular difficulties in caring for them. In that case, if they were planted in fertilized land, then you only need to water the beds and remove weeds as needed. In order for the flowers to be very large and have a strong stem, they can be fed 1 or 2 times.

Features of care and cultivation

For the cultivation of this type of flower is perfect open, well-lit place. However, you can plant them in the penumbra, but there the soil should be slightly moistened, and in any case not damp, as this will weaken the plant, and it will become susceptible to various diseases. Astra can easily grow in the same place for no more than 6 years. It should be noted that its root system develops very quickly.

Caring for such plants is very simple. In addition to watering and weeding, you should regularly loosen the soil, but be careful not to disturb the root system. Asters should also be systematically treated for diseases such as powdery mildew and gray mold.

Reproduction and transplanting

The procedure of reproduction and transplantation is carried out in the springtime. Astra is propagated by green cutting. Young shoots, which can propagate the plant, begin to grow directly on the trunk in the spring or summer months. Their rooting is pretty quick and easy. These cuttings grow in a short time and become quite strong bushes.

Another kind of asters (octo) can be propagated due to the separation of the rhizome. And it is also possible to grow such flowers from seeds. But this is quite a difficult task and a positive result is not guaranteed.

Perennial asters look great in rose gardens and gravel gardens. Violets, geranium, stonecrop prominent, badany and other flowers are perfectly combined with these asters.

Annual asters are divided into 3 classes: transitional, tubular and reed (depending on the shape of the petals).

These classes are divided into grades:

  • casing - they bloom for a long time and have a large number of inflorescences,
  • cut-off - designed for the design of bouquets, have double flowers and rather long stems,
  • pot - have small compact bushes,
  • universal - used for decorating bouquets and for decorating the garden.

Astra Transition

In this species, the flowers are reed and tubular. They are divided into types: semi-double, simple and coronary.

  • Simple asters - have flowers with straight reed petals. They are arranged in several rows and frame a flat basket, in the middle of which are placed small yellow tubes. Among them are such varieties as: Margaret and Zonenshain (cut), as well as Zonennkugel, Apollo, Edelweiss and Waldersee (casing).
  • Semi-double asters - they also have reed petals, but in greater numbers. They are also located around a well-marked yellow core. Petals bristling up and sides, due to what the flower looks more voluminous. Six grades are distinguished here, namely: Anmut, Victoria Baum, Mignon, Rozzet (casing), as well as Madeleine and Anemovidovidnaya (cut).
  • Asters coronary - in this type of flowers are very lush and very similar to small pom-poms. The core is almost invisible. Here are the varieties such as: Ambria, Pompon, universal princess bouquet (casing), as well as Fantasia, Aurora, Princess, Laplata (cut).
