Needle asters will decorate autumn flower beds in the garden and flower arrangements. Plants are annuals and require cleaning at the end of the season. For planting choose a lighted place on a hill.
The flower is resistant to lower temperatures, easily tolerates short-term drought. For abundant flowering, it is enough to water the plantings and periodically make mineral fertilizers.
Astra needle Unicum mix includes several varieties that differ in hue inflorescences. Plants have a pyramidal shape, reach a height of 50-70 cm.
Inflorescences are single, flat, radial, densely double. The size of flowers is up to 15 cm. During the growing season, each bush produces about 10-12 shoots and 30 inflorescences.
The color range of needle asters is extensive and includes the following shades:
Aster needle stands out early flowering. The first buds appear 3-4 months after the emergence of shoots. Flowering is long, continuous for 50 days from July to September.
Asters are light-loving plants that are resistant to short frosts down to -4 ° C. They are used to design multi-flower and single beds, mixborders and borders. The plant will decorate country and city beds.
At home, asters are planted in pots that are kept on well-lit balconies or loggias.
Needle varieties are grown for cutting. Flowers stand in water for 14 days. From them create monophonic or contrasting bouquets. Asters look spectacular in combination with greens.

Needle asters are grown seedlings. Seeds are planted in the prepared substrate at home. Seedlings provide the necessary microclimate. Grown up seedlings are transferred to open areas.
Seed and soil preparation
When growing needle asters, seeds are planted from March to April. For planting use a light fertile soil. Soil taken from the dacha and fertilize it with humus. It is allowed to use the purchased land intended for seedlings.
Pre-soil treated for the purpose of disinfection. It is steamed in a water bath or left for several weeks in the cold. Before planting, the soil is watered with a warm solution of potassium permanganate.Attention! Needle aster seeds are soaked in warm water. During the day the water is changed regularly.
For seedlings take boxes or cassettes with a mesh size of 3-5 cm. When using cassettes or individual cups, you can avoid picking seedlings.
The soil is moistened and poured into containers. Aster seeds are buried by 1 cm, a thin layer of earth is poured on top. In the cassette is placed 2-3 seed. Landings covered with polyethylene to create a greenhouse effect.
Seed germination takes 10-14 days. The film is turned over periodically to provide fresh air. Moisturize the soil with warm water. Faster seeds sprout a year earlier.
When shoots appear, polyethylene is removed and containers are moved to a lighted area. The development of needle aster seedlings occurs when a number of conditions are met:
- temperature range 16-18 ° C;
- regular watering;
- lack of stagnation of moisture and drafts;
- lighting for 12-14 hours.
Seedlings of needle varieties watered with warm water from a spray bottle. If necessary, set the backlight. Fitolamps are used for it, which are located at a distance of 30 cm from the plants.

When the first and second leaves appear, asters are seated in separate containers. When growing flowers in the cassette choose the most developed plant.
3 weeks prior to transfer to the soil, the plants are hardened. Capacity with seedlings rearranged on the balcony or loggia for several hours. Consistently, the aster period in the open air is increased.
Landing in the ground
Asters are transferred to the open ground at the age of 60-65 days. Land under the flower garden is prepared in the fall. They dig it up and fertilize with humus.
Asters prefer drained light soils. When grown in heavy clay soil, coarse sand is necessarily applied. The flower garden is not settled in the lowlands, where moisture accumulates.Tip! Asters are planted in open ground in May.
Planting holes are prepared on the garden where plants are transferred. 30 cm are left between them. Aster roots are covered with earth and produce abundant watering.
In regions with a warm climate, asters are planted immediately in open ground. Under natural conditions, the cultivation of needle asters from seeds takes longer, so the flowering time also shifts. When planted in the fall, the seeds undergo a natural stratification. In spring, stronger shoots appear.
In May, when warming up the soil, needle-aster seeds are planted on an open area. Pre-seeds are soaked for a day in warm water to stimulate their germination.
On the bed prepare furrows 2 cm deep, where the seeds are placed. For the night of landing cover agrofibre. When shoots appear, they are thinned or planted.
To accelerate the emergence of sprouts, seeds are planted in the greenhouse. In warm conditions, aster germinates faster. When the seedlings grow, they are transferred to a permanent place.

When podzimny planting flowers grow stronger, resistant to disease and adverse conditions. Seeds remain in the soil for the winter and undergo natural stratification.
Needle asters are planted in October or November, when the ground starts to freeze. Seeds are placed at a depth of 2 cm, ground and humus are poured on top. When podzimny planting increases the consumption of planting material, since the most viable seeds sprout in the spring.
Landings cover with agrofibre, it needs to be removed in the spring when frosts end. After the snow melts, the first shoots appear that thin out or transplant.
Flower garden care
When growing from aster seeds, needle-shaped, the Unicum mix needs minimal care. Enough to water and feed the plants. If necessary, planting is treated for diseases and pests. Dried inflorescences eliminate that stimulate the formation of new flowers.
Needle asters are watered as the soil dries. Pre-water settled in barrels. It is best to water the plants in the morning or in the evening when there is no direct rays of the sun.
The intensity of watering increases in the heat. On 1 square. m landings required 3 buckets of water. With a lack of moisture aster loses decorative properties.
Excess moisture leads to decay of the root system, the plant develops slowly and may die. Waterlogging provokes the development of fungal diseases.Tip! After rain or watering, it is necessary to loosen the soil to a depth of 5 cm. Loosening improves the absorption of moisture and nutrients by the roots.
Be sure to eliminate weeds. Prior to the emergence of a large number of shoots, stem stem up to strengthen the root system.

When grown on poor soils, asters are fed with minerals. If the flower garden grows on fertile soil, then you can do without dressings.
During the season, aster needle varieties are fed according to the scheme:
- 15 days after planting plants in the ground;
- when forming buds;
- before flowering.
Asters react negatively to the introduction of fresh organic matter: mullein or bird droppings. To obtain a nutrient solution, take mineral fertilizers: 20 g of urea, 30 g of potassium sulfate and 25 g of double superphosphate. Substances are diluted in 10 liters of water and watered the plants under the root.
Asters use wood ash for top dressing, which is embedded in the soil between the rows with plants.
For the second and third treatment, only potash and phosphate fertilizers are needed. Such dressings strengthen the plant immunity and accelerate the appearance of new buds.
Diseases and pests
With proper cultivation from aster seeds, needle-like Unicum mixes rarely suffer from diseases. The factors provoking the spread of diseases are high humidity, poor-quality planting material, growing asters in one place for several years in a row.
The greatest danger to the flower bed is Fusarium. The disease spreads the fungus that infects the stems and leaves of the plant. As a result, the flower turns yellow and fades. The infected plants are removed, and the soil and garden tools are disinfected.
When grown near conifers on the asters, rust appears in the form of blisters on the leaf plate. Flower bed sprayed Bordeaux liquid.Tip! For the prevention of planting diseases treated with a solution of Fitosporin.
Asters are attacked by scoops, meadow bugs, aphids, spider mites. Insects feed on the aerial parts of plants or their roots. As a result, the development of a flower slows down, which can lead to its death.
To get rid of pests, use drugs Malbofos, Metaldehyde, Phosphamide. They are diluted with water and used for spraying the plants. For the prevention of a flower bed dusting tobacco dust or wood ash.
After flowering, annual asters are dug up by the roots. Plants are encouraged to burn to eliminate pathogens and insects.
Aster seeds are collected in the autumn. Then on the bushes leave a few inflorescences. The collected material is recommended for planting for 2 years. Seeds are stored in a dry place in a paper or cloth bag.
Needle asters - frost-resistant and unpretentious variety of autumn colors. Asters look advantageous on the garden and in bouquets. Flowers are grown from seeds. Landing perform at home or immediately to the open area. The seedling method is considered more reliable and suitable for a cool climate.
Caring for a flower garden is minimal and consists in watering and weeding. For abundant flowering plants are fed with minerals.
