The flowering time in the middle zone of the country falls on the beginning and middle of autumn, and in the southern regions the aster blooms closer to November.

American aster is a herbaceous plant for open ground, characterized by good frost resistance. Certain plant varieties tolerate a drop in air temperature to -5 ° C. Aster grows in one place for about 5 years. It is used as an ornamental garden plant or for cutting to form bouquets and other compositions.

Breeding features

American bush aster reproduces:

  1. Seeds. There are two known methods: seedling and seedling. At the first, seed is planted in open soil. And in the second - into the container.
  2. By dividing the bush. This method involves dividing an adult bush into small parts, each of which has 3-4 shoots and a viable root system. An adult bush can be dug up completely, then divided and transplanted to another area, or cut off with the tip of a shovel and only the growing part can be dug out. The aster is transplanted in this way in spring or autumn after the end of the flowering period.
  3. Cuttings. In this case, cuttings are cut - shoots 10-15 cm long with two buds. The resulting material is planted in a greenhouse until the root system is formed. After the final rooting (after about 1.5 months), the mature shoots are transferred to open ground.

Important! At first, it is necessary to create greenhouse conditions for the cuttings, covering them with plastic wrap or glass overnight.

Seeds of New England varieties are usually sown in a container

Application in landscape design

The high decorativeness of the New England aster and the successful neighborhood with many plants makes it possible to use it to decorate the backyard area.

New England aster is a good solution for the formation of flower beds and flower beds. If you plant it along the fence, you get an impromptu hedge. Lush bushes with bright flowers look harmonious next to shrubs and low trees. And compositions of cut flowers will decorate any room.

New England Aster can be a good way to decorate territory.

Planting and caring for the New England aster

Perennial New England aster is an unpretentious plant. Nevertheless, for its growth and normal development, certain rules for planting and further care should be observed.

Timing

Optimal time for planting seed in open soil:

  • deep autumn (mid-November);
  • winter (all 3 months);
  • spring - after warming up the topsoil, that is, from mid-April.

To obtain seedlings, seed material is planted in a container in March.

Advice! The most suitable time for planting in any way is spring.

Site selection and soil preparation

New England aster is a light-loving plant, for this reason it is better to plant it in open areas, closed from drafts. Planting asters in an area with insufficient lighting leads to stretching of the stems and a decrease in the diameter of the flowers. A site with a close location of groundwater is also not suitable.

Warning! New England aster is a tall plant. Therefore, the site for its planting must be protected from wind that could break its stems.

It is better to choose a loose, fertile soil. If the land on the site is depleted, it will have to be fertilized regularly.

The area chosen for planting is dug up, weeds are removed and the soil is fed at the rate of 50-60 g of complex mineral fertilizers and one bucket of organic (burnt out cow manure or compost) per 1 sq. m of land.

Landing algorithm

American Aster seeds can be planted either in open soil or in a container.

For sowing in open ground:

  • shallow grooves are made (7-8 cm);
  • seeds are planted and covered with a 5 mm layer of earth;
  • the beds are watered and covered with foil;
  • after the formation of the 3rd true leaf, the seedlings dive;
  • when the seedlings grow up to 10 cm, they are transplanted to a permanent place, leaving a distance of 40-50 cm between the bushes.

To plant seed in a container:

  • fill the seedling container with soil mixture;
  • sow seeds, deepening them by 1 cm;
  • evenly moisturize the soil;
  • cover the container with glass to create a greenhouse effect;
  • aster seedlings dive after the formation of the 3rd leaf.

In open ground, the New England aster is planted about 65 days after the seed has entered the soil. This should be taken into account when calculating the date of sowing seeds for seedlings.

In the process of planting seedlings:

  • shallow holes are made, on the bottom of which drainage is placed (you can use large pebbles) and humus or mineral fertilizers;
  • place the seedlings in the center, cover them with earth and lightly compact them with your hands;
  • holes with seedlings are watered, the soil is mulched with straw, last year's leaves or sawdust.

Attention! The spacing between bushes should not be less than 50 cm.

After the formation of the 3rd leaf, a pick is made

Follow-up care

Caring for New England Aster includes:

  1. Moderate watering. You need to moisten the soil as it dries. Excess moisture can provoke root rot and the subsequent death of the bush.
  2. Removing weeds as they appear.
  3. Loosening of the soil (in the case of mulching the soil, there is no particular need for loosening it).
  4. Sanitary pruning - removing dried flowers and leaves.

For better flowering, the aster should be fed. After the appearance of the 4th leaf, complex fertilizers are used, and during flowering, potassium-phosphorus fertilizers.

Closer to winter, the aster branches are cut off, and the remaining parts of the plant are poured abundantly with water and covered with fallen leaves.

Warning! You should start feeding the aster from the 2nd year.

At the end of autumn, the aster branches are cut off, and the remaining parts of the plant are watered, after which they are covered with fallen leaves.

New England asters require moderate hydration.

Diseases and pests

American aster is disease resistant. However, improper care can lead to such problems:

  1. Powdery dew. The manifestation of the disease is a white bloom on the surface of the leaves. For the treatment of the disease, chemical agents for flowering plants (Topaz, Fundazol) are used.

    A sign of powdery mildew is a white coating on the leaves.

  2. Rust. This disease affects the underside of the aster, causing the leaves to turn brown. In the process of rust treatment, plants are treated with a Bordeaux mixture.

    To get rid of rust, the plant is treated with Bordeaux mixture

  3. Jaundice. Typical signs are yellowing of leaves and a decrease in flowering intensity. Insects become the spread of the disease, for this reason, the only means of combating jaundice is the destruction of pests with insecticides.

    With jaundice, yellow leaves appear

  4. Aphids are the main enemy of the New England aster. You can deal with it with the help of special preparations for the destruction of flower pests.

    Due to the small size of the pests, it is not always possible to detect immediately

Conclusion

New England aster is a flowering perennial plant that, with minimal care, will delight with its beauty until the very frosts. Good frost resistance allows you to grow aster in almost all regions of the country.
