Asters are perennial and annual plants of the Aster family. Adult plants in height can reach from 20 to 200 cm (depending on the variety). The leaves are simple, toothed. Stems are long, non-branched (for annuals) and branched (for perennials). Inflorescences are reed, tubular and transitional. There are a lot of shades of aster, but the central petals are mostly yellow. The plants are cold resistant.Just do not forget that these stimulants are not feeding, and it is still needed for the formation of a favorable growth soil.After that, the selected piece of land is dug up, and then digging is done in the spring. At the same time, it is necessary to add potassium salt and superphosphate.Asters begin to bloom, depending on the variety and mode of cultivation, from late June to mid-August. Flowering continues until frost.With
More details:RecklessThese beautiful flowers are very popular because of their unpretentiousness and long abundant blooms. Annual asters are grown in two ways: seedling and, accordingly, seedless. Each of them has its pros and cons.
You can sow, ascend, as the time comes. You can sow petunia, the rain will pass, will rise.
I plant open ground in May
Now it is not necessary in the snow, there will be return frost, and they need warmth for germination. In 2011 I had such peonyThe seeds of annual asters are sown at the end of March in the soil of the greenhouse. The sprouted seedlings are planted in open ground at the beginning of May, the distance between the seedlings must be at least 20-30 cm. Place for seedlings must be carefully prepared: it must be sufficiently moistened and be in an open sunny place.
Of course, watering is an integral part of care. It should be regular so that the plant develops well, grows quickly, and soon begins to delight the eye with its flowers.You can sow seeds at a convenient time for the gardener: either in spring or in autumn. The only thing to consider is the climatic conditions. In the Moscow region, you can in both seasons, but in the Urals it is better to do this in the spring so that the severe frosts will not kill the plant. By the way, I always sow asters in the spring months too.Many varieties of asters rather well set up seeds in conditions of central Russia. To save the variety that you like, you need to wait until the petals on the inflorescence wither and its center darkens and white fluff begins to appear on it. Such inflorescences are torn off, put in paper bags and dried in a warm, dry place. On the package you must write the name of the variety or at least the color and shape of the inflorescence and the year of collection of the seeds.
Master class on growing aster seedlings
In a way.Sowing seeds for seedlings should begin from mid-March to early April. Prepare planting material, for this you need to soak it in advance in the growth stimulator. Dilute the drug in accordance with the instructions. Spread the seeds on a frost case, cover them with a cloth and pour in the solution. Hold them for a day. Then dry. Prepare a substrate for planting seedlings. The simplest thing is to use a ready-made universal soil, but you can make up the soil mixture yourself. To do this, take 2 parts of leaf humus, add 1 part of peat and some sand or vermiculite to loosen the substrate. Pour the soil into a plastic container. Smooth the surface, place on it the prepared seeds of asters and sprinkle with a layer of soil in 0.5 cm. Cover the container with a film and place in a warm sunny place. The first shoots wait in 3-5 days. Wipe the film from this improvised greenhouse daily, as condensate accumulates on it. Plant it in an open ground for a permanent place in the middle of May. And in a couple of months, the aster, planted in this way, will delight you with lush flowering. When the seedlings have 2-3 true leaves, they will need to dive into separate cups.If somewhere in the Krasnodar Territory, in the Kuban region or in the Crimea, it is likely. We are in the suburbs only through seedlings. In the open ground in the middle of May, calendula or nasturtium, and what may be.
Only when the threat of frost has passed.
Yesterday I sowed asters. We need to sow early in the Urals to bloom in August. I sow in the usual way, not on snow. Today, the new moon, sow no need, tomorrow you can, if you stick to the lunar calendar. I didn’t look at the lunar calendar last year, but still everything grew beautifully.Perennial asters reproduce by cutting or dividing the rhizomes. To do this, in the spring you will need to cut off the green stems that have appeared and plant them in moist soil. If necessary, place the cutting in a container with water until the roots appear, and then land in the ground. The distance from each other, as well as for annual plants when landing in the ground should be 20 cm.If everything necessary was done for the soil in the fall, it is not necessary to contribute nutrients. But they never hurt. Asters recommend feeding with mullein.
It used to be better, because wet soil will guarantee excellent shoots. After the seeds for seedlings are sown, it is advisable to cover the area with a film so that in case of frosts the flowers do not die. It will need to be removed when shoots appear.
The only minus is that seeds, during storage, rather quickly germinate: after 1-2 years from 90-95%, it drops to 40-50.
The way the seeds are sown in the soil in early spring, as soon as the soil is ready. Seeds are sown in shallow grooves, covered with a layer of soil of 0.5-0.8 cm, well watered and slightly mulched in dry weather or covered with a covering material before germination.
Perfect soil and time to plant
This is less time consuming, rather than growing by seedlings, so many growers recommend growing asters like this - planting plants immediately in open ground for a permanent place. This can be done both in spring and in autumn. For autumn sowing, prepare a place for asters in advance. Dig a flower bed, remove the rhizomes of weeds and apply a complex mineral fertilizer and humus. Start sowing the seeds of asters from the beginning of October until frost. Make grooves, spread out planting material in them, and sprinkle with humus on top. In the spring, when asters go to growth and the first true leaf appears, thin out the seedlings. Caring for seedlings is watering, weeding and loosening. Similarly, asters can be planted in the spring. Prepare the soil and sow the seeds soaked beforehand in the growth stimulator. Then pour the grooves, cover planting non-woven covering material and wait for seedlings. Asters, planted directly in open ground in spring, will bloom in early to mid-September. If you want chic asters on your site to bloom from mid-summer to late autumn, plant them in seedling and seedless ways.
I have a knee-deep snow there. It was minus 14 at night. Asters sowed on Sunday in a bowl — they were already soldiers yesterday. And the marigolds, I'll sow them later. They stretch to the end of May.
This is interesting in what way? Today we are snowing.
So this: firstly, sow asters should be in the middle of March.
How to sow asters on seedlings?
It is enough to loosen, weed, moderately moisturize and fertilize the soil. Astra does not tolerate excessive moisture. Also no less important is the regulation of the growth of shoots in tall varieties.
If this is not possible, you can always buy fertilizer from mineral fertilizers, as well as ammonium nitrate or urea. Complex options will also be harmless, because they already have everything that is necessary for the plant.
Replanting is necessary when the sprouts are fully prepared for this. The main thing is the level of their development. It is not necessary to move to the beds, if they are still weak, only with a pair of first leaves. Let better pass more time. Asters should rise above the ground by about ten centimeters.
Care for bright beauties
Greetings to you, my readers! Diverse, bright, fragrant, incredible colorful and picky - this is aster. Probably, even a child will be able to distinguish them from any other colors.
Well-developed seedlings in the phase of 2-3 true leaves are thinned to a distance of 10-15 cm. It is better not to pull out extra seedlings, but to carefully dig out and transplant to another place.
Of course, the main reasons for the popularity of the annual aster are beauty and diversity. Unpretentiousness plays a significant role.
We have snowed, I sow everything in the middle to the ground in April, but then I still sit down, even if it is not very cold, they will still grow well and the seedlings will be hardened, CHELYAB OBL
Watching where. The asters are early, but the marigolds can probably be them for me each year they fall asleep themselves
It is necessary to sow on snow like this: gather the earth in a jar and put snow on it from above, compacting it well. Seeds are laid on the snow, the jar is covered with film and put in the refrigerator for 3 days. Then transferred to the window, the film is not removed until the emergence of seedlings - only sometimes airing.
At the end of March - beginning of April, the seeds are sown in boxes or directly into the ground of the greenhouse - into the grooves, powdered the seeds with earth (0.5 cm), watered with a light pink solution of potassium permanganate and covered with paper or film. So that the seedlings do not get sick with the “black leg”, the seeds before sowing powder with fungicide, and the soil is shed with a solution. After 3-5 days, when shoots appear, remove the paper from the boxes and put them in a bright place so that the seedlings do not stretch out.

In April under the film. It is possible to snow the house, so that the seeds are drawn into the ground. Asters at home planting do not like burial in the soil.
Share the article with friends, even if they have a beautiful multicolored carpet of these beautiful flowers at their dachas. And by subscribing to my blog you will read all the new useful articles in time.
Asters, though not picky in the care, but still need to monitor them. The biggest trouble that can happen is damage from parasites. To prevent this from happening, after a week and a half after planting it is recommended to treat them with drugs containing copper.
Elena the Wise
Humus or compost (but not fresh manure, it contributes to the damage of plants by fusarium), complex or phosphorus-potassium fertilizers (40-60 g of nitrophoska or 60-80 g of superphosphate and 30-40 g of potash fertilizers) and wood ash ( 100-150 g) per square meter. But if the soil is well cultivated, rich in nutrients, then you can do without fertilizers. Before planting, seedlings are watered abundantly, especially if it was grown without pots.
When the first true leaf appears, the seedlings dive at a distance of 5-7 cm one from another into pots, a box or into the ground of the greenhouse, since aster seedlings tolerate transplant well even with an open root system. If the seed-knee knee of the seedlings is greatly extended, then they can be deepened when diving to almost the cotyledon leaves.
They are sown not only in spring, but also towards winter (over frozen soil, into previously prepared furrows). In this case, the plants are almost three times less likely to be damaged by Fusarium. Spring shoots thinned.
Planting plants is better in the evening at a distance of 20-30 cm (depending on the pomp and height of the variety). After 7-10 days after disembarking, asters can be fed with complex fertilizer and repeat feeding in 3-4 weeks. In dry weather, plants are watered moderately.
Outwardly, reed aster looks like a magnificent, shaggy ball, which has a yellow core with short tubules hidden inside. This includes needle, curly and ray asters.
- Needle asters are versatile plant varieties., these include "Riviera", "Valkyrie", "Corallen". Twisted in length, thin leaves of plants look like needles.
- Curly varieties have wide reed petals with curly tips; these are Chrysanthemum and California universal varieties - “Early Miracle”, “Ostrich feather”.
- Beam varieties have twisted, long, narrow petals similar to tongues. Between the petals do not grow together. These include shear varieties - “Unicum”, “Corallen”, “Artistic”.
Asters, from the class of transient, have reed and tubular flowers, collected in inflorescences. These include coronary, simple and semi-double varieties.
- Coronary asters similar to lush pompons with a barely noticeable core. Universal variety - “Princess Bouquet”, for cutting - “Aurora”, “Princess” and “Fantasy”. "Pompon" and "Umbria" are used for casing.
- Simple asters have a yellow flat middle. Around the core are located in several rows of straight reed petals. These include shear varieties “Margarita”, “Sonnenshine”, casing varieties - “Apollo”, “Edelweiss”, “Waldersee”.
- Half-shaded asters have reed petals that stick out in different directions, creating a three-dimensional look. At the same time, the core of the flower is clearly visible. This includes cut varieties "Mignon", "Rosette" and "Anmouth", as well as casing flowers "Victoria", "Baum".
Perennial asters are divided into two groupsthat bloom in early spring and late autumn. These are Alpine, bush, American, Italian (chamomile) and Virginian aster.
Asters, landing in open ground and care
Your garden will become beautiful and flowering, if, when planted, inGrowing and caring for a plant follow simple rules. Landing asters consists of several stages:
- The choice of location and soil preparation.
- Ways of planting annual asters in open ground (transplanted or seedless).
- Care and watering.
- Top dressing.
Place and soil preparation for planting
Place for planting is selected in those parts of the garden that are closed from the wind, as the plant is very afraid of drafts. It is good if it is an open sunny area, but partial shade is also suitable for it. Plant to start in the fall. For the flower buds to be healthy, the ground at the landing sites must be well drained.
The soil should not be too wet or wet, otherwise the roots may suffer, as the plant has a shallow root system.
As drainage use large river sand, humus and peat, which must be carefully weathered. The flower is planted in neutral soil. If the acidity level is elevated, lime is added to the ground.
At spring planting, the beds are dug up, adding ammonium sulfate and fertilizers (potash and superphosphate) to the soil.
How and when can you sow asters in open ground? Plant in soil in two ways.: seedling and seedless (seeds). Depending on the timing of flowering of each variety is chosen planting method. After shoot:
- Early varieties - bloom after 3 months.
- Average varieties - in 3-4 months.
- Late varieties - after 4 months.
When buying sachets with seeds, you need to carefully look at the expiration date, since they germinate for two years. Germination will be less by the end of the second year.
Growing asters in rassadny way is as follows:
- HToby the plant began to bloom in early summer, you need to prepare seedlings in advance. The seedlings are grown in greenhouses or at home in pots and drawers. Land can be bought at the store or taken from the garden. The main thing is that it is breathable, nourishing and fertilized. From the fertilizer suitable humus or compost. At the bottom of the box lay drainage, which will help the water to quickly leave.
- To prevent the appearance of a fungus, a box or a selected area for sowing in the greenhouse is treated with a weak solution of potassium permanganate. At 1 gram of potassium permanganate accounts for - 5 liters of water.
- Seeds are planted in the ground to a depth of 1 cm and watered with warm water. To maintain the desired temperature and humidity, boxes of seeds are covered with a film. The film is removed when the first shoots appear.
- Seedlings are transplanted into separate pots after two or three leaves appear and are watered abundantly.
- Landing start do early or mid may. Seedlings are planted in the evening, after watering the soil. Choose strong seedlings with a strong stem, which appeared from 5 to 7 large leaves. Seedlings are placed apart at a distance of 15 to 25 cm. The greater the distance, the larger the flowers.
You need to know that when planting seedlings in the ground, you can not bend the roots. When sprouting earth, the main thing is not to fall asleep growth point.
The site for asters is prepared in the fall. Planting early varieties begin to do in early March or in the middle of the month. Later varieties are sown at the beginning of May, when the land is warm enough.
- First, make small grooves with a depth of 0.8 cm. At a distance of 2.5 cm from each other sow the seeds, sprinkling them a thin layer of soil and covering the film.
- В момент засухи их мульчируют или накрывают защитным материалом. Когда появятся первые ростки защиту можно убирать.
- С появлением двух-трех листочков сеянцы прореживают. Оставляют самые развитые и крепкие ростки. Расстояние между ними должно составлять 15 см. Остальные растения аккуратно, чтобы не повредить корни, достают из земли. Затем высаживают на другие клумбы.
You can plant aster seeds in open ground in winter. Sowing is carried out from December to January, when the height of the snow is 10–15 cm. For humus, humus and peat compost are prepared in advance. Planted plants in winter are less susceptible to diseases, have a well-developed rhizome, bloom longer. The only negative - do not have time to ripen the seeds. In the spring, young plants are transplanted, creating a beautiful flower garden.
Planting by breeding
In addition to seeds and seedlings, aster can be propagated by vegetative method. This method is suitable for perennial asters. Reproduction occurs with the help of apical cuttings or dividing the bush.
- The division of the bush produced in early spring. To do this, choose the strongest plant. Each divided part should have more than three shoots and a good rhizome.
- Reproduction using cuttings done in the middle of summer. Cuttings 7–8 cm long are planted in the ground, under a film or in a greenhouse. The land should consist of a mixture of peat, turf and sand. You can plant cuttings in open ground in late August - early September.
Care and watering
In order for the plant to be healthy and beautiful, you need to properly care for it. If the land for planting was prepared correctly, then the care of aster will be simple. The main thing is to do it in time. weeding from weeds, watering and feeding, and also not to forget to loosen the soil.
- The appearance of small flowers and reduced terryiness is due to insufficient watering.
- Flowers need spudding on time, otherwise they will begin to branch.
- Loosening of the soil is carried out after irrigation or rain at a depth of 6 cm, because the roots of asters are very sensitive.
In hot weather, the aster must be watered regularly and abundantly, otherwise it may dry out. Do not allow the soil to dry out during budding.
Any plant must be fed fertilizer. Before any top dressing, the plant is watered abundantly. 15 days after planting the seedlings into the soil, make the first feeding complex fertilizers. During the flowering period, top dressing is removed and replaced with phosphate-potassium fertilizer. The plant should be fertilized 2 times a month.
If nitrogen substances are used for feeding, then inflorescences will become smaller, and the number of leaves will be greater. For poor soil use organic fertilizers. This may be a mullein infusion, which is insisted about three hours.
Diseases and treatment
Fungal diseases, viruses, aphids and mites can damage the plant, even if it is being carefully cared for. Therefore, you need to know how to prevent the disease:
- Slugs and nematodes appear at high humidity and moisture.
- In order to avoid fungal diseases, the place for sowing seedlings of asters is changed annually. You can not plant a plant where they grew tomatoes, chrysanthemums, daffodils and gladioli. Because, they are affected by the same fungal diseases, as well as asters.
- Soap solution from leaf tobacco will help destroy insects and slugs.
If you regularly spray a plant with a solution of potassium permanganate, cobalt, zinc and magnesium salts, you can prevent disease. A solution of copper sulfate and boric acid is also suitable as a prophylactic agent.
What are asters?
Asters are beautiful velvety plants of the Asteraceae family.. It is curious that everyone is accustomed to consider asters a flower, in fact they are an inflorescence. One spikelet contains several sterile (incapable of reproduction) flowers, wrapped in so-called tongues, which are mistaken for petals. In the center of the inflorescence are small flowers in the form of tubules, as a rule, yellow.
The genus Asterov includes about 200 species. Here are the most popular ones:
- Alpine aster has purple or reddish reed flowers (26–60 pieces per inflorescence), as well as tubular yellow flowers in the middle, reaching a height of from ten to thirty-five centimeters. Basket with flowers in diameter of five centimeters. It blooms in summer (from June to August), unfortunately, is listed in the Red Book of several regions of Russia (Tatarstan, Sverdlovsk, Tyumen Oblast, and so on). Interestingly, this plant is used in Tibetan medicine as a cure for gastrointestinal diseases,
- Astra Chamomile is also called wild, steppe, European. Its area covers Europe, the Mediterranean, Siberia, the Caucasus and the Baltic states. The baskets of flowers are smaller than those of alpine asters; they reach from three to five centimeters in diameter. The flowers are different colors - from purple to white. Externally, it strongly resembles chamomile, which is why the species got its name. Varieties are not resistant to pests and diseases, especially under conditions of soil erosion and excessive water stagnation. Popular varieties: Dwarf, Kobold, Lady Heindlip, Hermann Löhne,
- Siberian Astra is considered an endangered species in the Yamalo-Nenets Autonomous District, and therefore it is listed in the Red Book. It happens blue, white, purple. Inside the basket are yellow flowers, like all other asters.
Do not confuse aster with callistefus (which is popularly called “garden aster”). Callistepus has rounded edges on sterile flowers, aster has a sharper and elongated inflorescence. Previously, these two different kinds of plants were united into one genus due to a number of similar characteristics, which is not surprising, since they are close relatives to each other. Interestingly, among the genus callistefus distinguish only one representative - Callistefus Chinese.
Early spring planting of seeds
Landing is carried out either in the middle or end of April, or in early May. The choice of the month depends on the climate, ambient temperature and soil type. For light soil on the southern slopes, planting is suitable in April, and for heavy loamy soil - in May. It is very important not to delay the sowing of early-ripening varieties. The optimum temperature of germination is + 20–25 degrees Celsius (after climbing the best temperature is + 16–18 degrees, therefore before aster germination it’s better to cover it with a film to raise the temperature).
Before sowing in the open ground, the flowers must be treated with a solution of potassium permanganate (a 0.5% solution is suitable, for this you need to mix 200 ml of water and 1 g of potassium permanganate), and preferably with any fungicide. Processing must be done in a cup with a pre-prepared solution. A rag with seeds is immersed in it, held for 25 minutes, the seeds are removed and washed with running water. Such seeds will be more viable and have less risk of getting sick.
Before planting asters, the earth is cleared of weeds and debris, add compost or fertilizer. Do not add fresh manure, because of this increases the risk of fusarium disease. Planting depth should be 0.5 cm, and the distance between the flowers should be at least 3 centimeters. Srednerosly and tall varieties are best planted away from each other, otherwise they will begin to compete.
Late spring planting seedlings in the ground
Early and mid May You can transplant seeds pre-grown in containers. Seedlings should be strong and have 5-7 leaves. Flowers are planted according to the scheme of 20x20, 30x30 and 40x40 centimeters, the choice depends on the type of plant. It is not necessary to plant close tall asters. If the bed has not been fertilized with anything for the last 2 years, then compost or manure should be added, and mineral fertilizers should be added to the wells (3-5 grams). It is worth considering that different varieties have different cold resistance. Hardened seedlings carry frosts up to -4 degrees and can be planted a little earlier.
After May 20, annual asters can be planted. Cloudy weather is best for them. If the weather is stable and sunny, then it is best to replace them either early in the morning or after five in the evening. Seedlings should be watered before planting. It is important not to damage the roots when removing the plant from the container. It is best to transplant asters with a clod of earth.
To seedlings better adapted to new conditionsit should be hardened. For this, pots with future flowers are brought to the balcony and left there for 1–2 hours, and the rest of the time they put the seedlings in the shade on the windowsill. It is necessary to gradually increase the number of hours of hardening, and over time to keep the seedlings on the balcony all day.
When the seeds are immediately planted in open ground, they adapt better than transplanted seedlings. They are easier to tolerate coolness, drought and begin to bloom faster, since from the very beginning of germination they adapt to environmental conditions.
Late autumn planting seeds
It is produced in the twenties of November.. In advance, it is necessary to prepare the beds (dig the soil, remove litter and weeds with roots, make furrows about 2 cm deep). Seeds are sown with the calculation of 70-80 pieces per meter (not all of them will rise to the beginning of the season). At this time of year it is difficult to make the grooves with soil, therefore they spread compost, peat or humus from above. The mulch layer should be approximately 2 centimeters in height and at least 5 centimeters in width. Seeds will begin to germinate in spring. You should not worry about short warming at the end of autumn, as a rule, temperatures in November do not rise to the point where seeds begin to swell and sprout.
Winter sowing seeds
The optimal month for winter sowing - December and January. To do this, you must prepare the beds with grooves in advance. Seeds are scattered over the snow, the height of which should reach from ten to fifteen centimeters (if the snowdrift is less than ten centimeters thick, then the snow may melt, while the seeds are washed away). Planted seeds from above are mulched with humus or peat, harvested in the fall. If in the spring there are no sharp temperature fluctuations, and the snow melts slowly and gradually, then no threat to the seeds is expected. With a very sharp warming, the seeds can wash away with melted snow.
Mulch and freshly melted snow create optimal conditions for the germination of asters, since the seeds are sufficiently supplied with moisture and do not overheat. If by the end of the spring too many asters have risen, then the bed is thinned, the extra asters are either thrown out or transplanted to another place (according to the scheme one plant at least 20 by 20 centimeters). As a rule, it is worth repeating this procedure in seven or ten days. Do not allow the soil to dry much, it can lead to damage by Fusarium. In early spring, the soil is loosened (the depth should not exceed five centimeters, and near the plant 2 centimeters, the roots of asters are located in the surface layer of the earth). When weeding, it is important to remove all weeds along with the root.
When the flowers grow, they will delight not only the owners of the site, but also all the incoming guests!
Place for a flower bed
Asters love the sun, but during the flowering period hot rays burn the petals, the flowers lose their brightness and attractiveness. It is advisable to plant the plants so that from the south side the sparse crown of a tree or a tall bush creates penumbra. It is good to break a flower garden to the north of a canopy with blinds: you can independently adjust the lighting. The site should be protected from drafts: Astra’s open air to all winds is not to its liking, and air currents can cause controversy of pathogens. Groundwater should not be high. If the site is located in a damp area, make an elevation, the design of the territory will only benefit from it.
Young saplings of asters can get fusarium. To avoid infection, plant flowers to a new place every year; you also do not need to plant them after carnations and gladioli. If you are going to break a flower bed on the former vegetable beds, avoid the areas where solanaceous crops grew. Well prepare the ground calendula and marigolds.
Asters like fertile soil, when laying a flower bed on poor soils, you need to bring black soil or peat. Sour earth does not like flowers, so look at the plants at the place of the future flower bed. If there is good growth of sorrel and rhubarb, when digging, add lime or chalk to the ground. You can do everything by science: first determine the pH of the soil. The result from 6 to 8 means that the reaction is normal, landing is permissible. For a unit to be added to the indicator, on light and medium soils, 350 g of lime per 1 m 2 must be added, on heavy soils, increase the amount to 400 g.
In the autumn, dig a bed deep, select weed roots and larvae of pests. On clay soil, add sand for drainage. A fresh manure asters is contraindicated, plants can get fusarium. Bring it in a reversed form or as part of a compost when digging.
When planted in open ground?
In central Russia, seedlings of asters in the spring can be planted in open ground in the second half of May. You can watch the weather forecast, find out when the warm days come. You can also believe national signs and planted when the bird cherry blossoms and the cooling that is attached to this phenomenon ends. Do everything in the right time - you will be with flowers in July.
Two weeks before landing, start preparing seedlings for new conditions. At home, the seedlings were warm and comfortable, now begin to take them out. First, let them "walk" for a few hours during the day, then, if frost is not expected at night, leave the boxes on the glazed loggia or unheated, covered veranda for 24 hours. Plants will harden, and it will be easier for them to survive the difficult time of rooting. Even if you don’t cover asters before a sudden freeze, the temperature not lower than -5⁰ sprouts, accustomed to living on the street, will survive.
A week before disembarking, dig a flower bed, adding for each m 2:
- phosphate fertilizers - 20-40 g,
- potash fertilizers - 15-20 g,
- ammonium sulphate - 15-20 g
Mark the wells. If you are going to grow asters with a high stem for bouquets, the distance between them should be at least 25 cm, so that the branches with flowers develop freely, do not interfere with each other. Curb varieties can be planted in 15 cm of one plant from another, they will create a continuous multicolored stitch or colorful carpet. When growing very large varieties with a stem height of more than 60 cm, the gap should be more than 30 cm.
Planting seedlings in open ground
Seedlings become ready for transplant at the age of 1.5-2 months; in early spring, when sowing seeds, be guided by these terms. A developed seedling should have 5-7 good leaves and a strong stalk 6-10 cm long. Be sure to water the plants one hour before transplanting in order to make it easier to remove them from the cups. It is desirable to hold the underground part of the plants in the growth stimulator, such a procedure will accelerate survival. The less the roots suffer, the better the asters will take root. Plant in need of cloudy weather, on sunny days, plan this work for the evening.
When places for plants are already marked, landing begins.
- Dig holes 20 cm deep, lay compost on the bottom and sprinkle with a layer of soil.
- Fill the pits with water, wait until it is absorbed into the ground.
- Immerse the seedling in the soil, deepening the above-ground stem by 2 cm into the ground, after planting it should be no longer than 7 cm.
- Straighten the roots so that they are pointing down, cover with earth and tamp lightly.
- Water the planting under the root and sprinkle sand on the surface of the soil or silence.
When the seedlings have outgrown, plant it so that the stem goes deeper into the ground by 3-5 cm.
No matter how carefully you get the seedlings, the roots will still be traumatized. Solve this problem in advance by sowing seeds in peat pots. You will only have to plant the seedlings together with the container in the ground and bury it to such a depth that the stem is the right length. Soon the pots will decompose into additional fertilizer, and the roots will freely pass into the surrounding soil.
Care for young asters
Asters do not tolerate drought. The main root mass is located no deeper than 15 cm, and the plants cannot extract moisture from a great depth. Water them abundantly: the soil should be saturated with moisture, but not turn into a swamp. You can add a little potassium permanganate to make the liquid a pale pink color. Watering is better in the morning: if you inadvertently overdo it and turn the flowerbed into a rice field, the sun will dry the excess moisture during the day and the roots will not rot.
In order not to have to tie up tall plants to the pegs, as you grow, roll up the asters. The mound will shorten the stem slightly and become an additional support for it. Additional roots feeding the above-ground part will begin to develop in the ground. Buds and leaves will get more moisture, minerals and trace elements, the plant will develop well and give you beautiful flowers.
The first dressing needs to be done approximately 10 days after planting, when the main part of the plants took root in a new place and began to produce new shoots. Use an infusion of ash, it will not only fertilize the soil, but also protect against some diseases, ward off pests and reduce the acidity of the soil. You can also make complex fertilizer. During the drought period, it is necessary to apply top dressing in liquid form, in wet weather, fertilizers are buried in the ground in solid form.
Asters bloom magnificently only in the loose earth. If you have taken care of and flowerbed the flowerbed, the need for additional work is eliminated, otherwise you will have to break the crust on the soil surface after each watering. A layer of mulch will also prevent overdrying of the soil, will not allow weeds to grow. Корни у астры располагаются близко к поверхности, чтобы не повредить их, рыхлите на глубину не больше 5 см. Следите, чтобы на посадки не напали вредители. Когда заметите подозрительных насекомых, сразу обработайте клумбу инсектицидом.
Чтобы астры весной быстро укоренились и начали хорошо развиваться, необходима крепкая рассада. Лучше выращивать ее в торфяных горшочках и вместе с тарой посадить цветы на грядку, тогда корни совсем не пострадают. It is better to buy seedlings from familiar vendors, so as not to acquire infected seedlings. For insurance, treat your purchase with a fungicide.
Planted in the open ground is better immediately after the end of frost. Hardened seedlings a slight cooling will not harm, but asters will bloom in mid-summer. Do not thicken planting, the distance between the bushes depends on the height of the plants. In the heavy soil make sand for drainage: the roots can not tolerate a wet soil.
Mulching facilitates the care of the seedlings: the number of waterings decreases, the soil does not need to be loosened and weeded. 5 cm of sawdust, pine needles or straw will allow you to save time all summer. Hilling of plants will relieve the flowerbed of unsightly garter pegs. Growing asters does not require hard work, but the whole second half of the summer and autumn you will cut the lush colorful bouquets.
2 ways of landing asters
Growing annual asters from seeds is possible in 2 ways: seedling and seedless. Germination lasts 2 years, so when you buy seeds you need to pay attention to the shelf life - by the end of the second year, germination falls. What method of planting asters to choose depends only on the timing of flowering of a particular variety. Early varieties after sprouting bloom after about 90 days, medium late - after 100, and later - after 120 days.
Growing asters from seedlings around mid-summer produces blooming plants. Asters are sown on seedlings in the last decade of March - early April, if by mid-May you plan to plant in open ground.
Growing asters for seedlings consists of several stages.
- First you need to prepare the soil, it must be nutritious, abundantly fertilized and breathable. You can take the land from the garden or vegetable garden, add sand, compost or humus (or peat). For disinfection, a solution of potassium permanganate is prepared - 1 g per 5 l of water - and the soil is poured with a hot solution. Boxes and pots for planting rinsed with the same solution. Drainage must be put on the bottom, be sure to easily leave the water.
- Seeds are buried by 0.5-1 cm, the water for irrigation needs warm. The next watering is done only after seed germination. It is advisable to cover the boxes with seed film to maintain temperature and humidity. After seed germination, the film is removed. Care of seedlings is to provide good lighting and not very high air temperature, approximately 18 ° C.
- With the appearance of two full-fledged leaves, seedlings need to be transplanted, preferably in separate pots. Although aster is not too afraid of transplantation, the base of the stem of the seedlings is very tender. Watering the seedlings is desirable abundantly, but rarely, avoiding excessive soil moisture, which contributes to the appearance of fungal diseases.
- It is better to plant asters in the open ground around mid-May, when the seedlings reach a height of 10-12 cm. It is better to plant the plants in the evening, water the soil beforehand and preferably mulch with grass or sawdust. Tall varieties are seated at a distance of about 30-40 cm, so that the grown bushes do not interfere with each other. Low species are best planted at a distance of about 20 cm, then the adult plants during flowering form a solid carpet.
- Place for planting asters need to choose a well-lit, dry, so that the water after watering for a long time does not stagnate. Growing asters in the place where they grew tomatoes or potatoes, is undesirable, in the soil after these crops often remain the causative agents of fungal diseases of plants. When disembarking, you should try not to bend the roots and not cover the growth point with earth.
Sowing aster seeds in open ground (off-seed method)
In the case of a non-seedling planting, asters are sown in 2 periods: in early spring or in autumn. During spring planting, crops are sown by the end of April - beginning of May, when the soil warms up sufficiently. In the autumn, asters are sown when the earth is already freezing in the previously prepared shallow grooves. Asters, planted in the autumn, bloom 10-15 days later, but bloom longer and more abundant.
- For sowing asters into the open ground, prepare grooves with a depth of about 2 cm, it is advisable to also pour the prepared beds with a solution of potassium permanganate, as well as the ground in containers prepared for seedlings.
- Seeds are sown in the prepared grooves, lightly sprinkled with earth, watered with fairly warm water and covered with a film during spring planting until germination. Instead of a film, you can mumble the grooves with garden soil or with humus — a layer of about 1 cm. Do not water the seeds until the seeds germinate.
- Thin out the plants after the formation of the third and fourth of this leaf, leaving the desired distance between shoots, depending on the variety. It is better not to pull out extra shoots, but gently get them out of the ground - and you can plant them on other beds.
When autumn sowing, it is impossible to close the seeds into the ground, since the soil has already frozen. Therefore, the seeds are mulched with humus 3-4 cm thick layer or compost. In the spring, when the earth thaws, you need to gnaw between the rows, leaving the mulch in place until germs appear.
Care for asters in the open field: watering and feeding
If the land for planting flowers was properly prepared, taking care of asters in the open field is so simple that it allows them to grow for beginner gardeners. Only timely watering and weeding of the beds will be needed.
- Watering should be planting as the soil dries, avoiding waterlogging. Growing asters on wet, heavy soils with close groundwater storage is highly undesirable, because it causes the roots to rot. In addition, asters need to loosen the soil to saturate it with oxygen. Regular weeding and weed removal contribute to the prevention of disease.
- If the summer was droughty, you can mulch the land under the asters of dry grass, sawdust or pine needles. This will keep the soil moisture between irrigation.
- Care in the form of feeding will be useful for asters. The plants are fed with mineral fertilizers: superphosphate, ammonium nitrate, potassium sulfate. You can also use wood ash. But nitrogen fertilizers should not be used for top dressing, since this leads to enhanced leaf formation and reduces the number of inflorescences.
- Fertilizers can be dissolved in water or in dry form. The first dressing of asters is made 2 weeks after landing in the ground. Fertilizers are applied a second time during bud formation, and a third time at the beginning of flowering.
Diseases and pests affecting asters
Asters are quite often affected by various viral and fungal diseases, even with fairly thorough care. We list the most common hazards.
Fungi usually infect the soil, their reproduction is facilitated by excessive moisture of the soil and high temperature of the air when growing asters. Annuals get sick more often, the disease appears in the form of dark stripes, and only on one side of the plant. Then the leaves begin to turn yellow, the buds wither, the plant dies.
To combat the disease, it is necessary to reduce the acidity of the soil by adding lime to it, sprinkle a flower bed with chlorine dioxide of copper, and make sure that there is no aphid.
The fungi that cause this disease are present in any soil. They mainly affect young shoots near the base of the stem, which becomes thinner, blackens, and the plant quickly dies. Contributes to the spread of the disease acidity and high soil moisture.
You can fight the disease with the help of disinfecting equipment and soil with a strong solution of potassium permanganate, removing diseased seedlings, maintaining optimum moisture and careful maintenance.
- Septoria (brown spot).
The causative agents of this disease are localized on plant residues. On the affected leaves appear rusty or light brown spots that spoil the appearance of the plant. Diseased leaves wither and fall. Fungi actively multiply at a temperature of 23-25 ° C and high humidity.
Caring for a diseased flower bed consists of spraying copper oxychloride or Bordeaux oil once every 2 weeks to help stop the spread of the disease. Be sure to destroy the affected plants.
- Mosaic disease, or jaundice.
The virus is transmitted by insects: aphids and cicadas. Light veins appear on the leaves, the plant stops growing, the buds do not bloom. It is impossible to fight this disease, there are only preventive methods: immediately remove diseased specimens, destroy insects.
Bacteria live in plant debris, they can also be infected with seeds. Brown spots appear on the leaves, stalks and buds, the disease begins during the formation of buds and spoils the appearance of the plant. Gradually, all the leaves are affected, dry and fall.
If symptoms of the disease appear, spray the Bordeaux mixture or copper chloroxide 2-3 times every 10 days.
For the prevention of fungal diseases, you can add an infusion of nettle or celandine to the water for irrigation. To prepare the infusion, you need to fill 1 kg of raw grass with a bucket of hot water, insist for 2-3 days, strain. When watering add about a glass of infusion to a bucket of water.
In order for the flower garden to delight until late autumn, it is enough to follow simple recommendations and take care of plantings:
- use proven healthy seeds,
- carry out seed treatment before planting,
- fight pests that carry diseases,
- remove diseased plants immediately
- avoid overmoistening the soil
- regularly loosen the aisles.
Astra is a real star of autumn flower beds. None florist does not ignore its raznotsvetie. There are about 600 species of this flower, striking a variety of shapes and colors. Growing special varieties in greenhouses will allow you to get blooming asters in early spring or late autumn. Simple rules for planting and caring for this flower will allow each gardener to grow asters on his site.
