Characteristics of the Novobelgian aster

The homeland of this species is the eastern region of North America, it is distributed in forests, steppes, highlands before the beginning of the taiga. It is a rhizome perennial plant with a reverse pyramidal shape.

The stems are strong, from 55 to 150 cm, have many branches in the upper part, and it depends on the varietal feature whether they are covered with hair or smooth. The bush is leafy, and the foliage on the stems is arranged in sequence. Leaves are lanceolate with an obtuse base, sessile, elongated, have slightly serrated edges. The rhizome is thin, horizontal and highly branched.

Flowers are collected in inflorescences in the form of baskets, consisting of many small flowers. Inflorescences are large, paniculate, sometimes include up to 200 fragments.

Reed, located at the edges have bright shades: pink, yellow, crimson burgundy, blue, red, white. And in the middle of the inflorescence are tubular yellow - the middle. They are small in size, the average width is 2-5 mm, and the diameter of the inflorescence is from 2 to 8 cm.

In such tubular centers, flat, long, dark-colored seeds are formed. Each seed has a "parachute" like a dandelion, thanks to which it flies well from the mother bush.

Flowering occurs at the beginning of autumn, and flowering caps persist even with the onset of frost.

Planting and propagation rules

Asters are not pretentious plants, they like well-lit sunny areas, protected from strong drafts. Growing in the shade noticeably slows down their development and leads to stretching and fragility of the stems.

The soil is desirable nutritious, loose with a depth of the fertile layer of at least 25-30 cm. If the soil in your area is too acidic, you can neutralize it with dolomite flour. Landing is of several types.

Seedless

That is, sowing seeds directly into the garden. Sowing is carried out before the onset of cold weather in November and December. If you bought seeds from a store, they must be kept in the refrigerator for about a week and soaked at room temperature for 7 hours.

And if the seeds are just ripe and grown independently, then they do not require additional preparation. The seeds are spread over small grooves, thoroughly watered with warm water and lightly sprinkled with soil.

After the appearance of the first 3 leaves, it is recommended to thin out. Try to keep the distance between young shoots 12-15 cm.

Seedling

It is carried out more often after purchasing seeds, which, as in the previous method, are scarified. The soil for planting is bought in a store or prepared independently.

For this, peat, mullein, coarse sand and turf are mixed in a ratio of 7: 1: 1: 1 and the resulting mixture is spilled with a weak solution of manganese for disinfection. After sowing, the containers are placed in a lighted and warm place, and the seed is often watered and ventilated.

After the sprouts appear, it is advisable to lower the temperature to 15 degrees and install additional lighting in the form of photo lamps. Young plants are fed several times: when 3 true leaves appear and 6-7 days before planting in open ground. Seedlings are planted at the age of 62-65 days, having previously hardened them at a temperature of +10 degrees.

New Belgian aster loves space, so it is better to plant seedlings at a distance of about 40 cm, while other plants should be drought-resistant, as it grows quickly and will actively consume moisture from the soil.

Flowering after transplantation to a permanent place occurs in a year or several years.

For varietal flowers, propagation by cuttings is suitable. Cuttings are carried out in May - June to August. Cuttings are used from the top, 6-7 cm long. The cut shoots are planted in fertile soil (the ideal composition is turf, sand, peat, 2: 1: 1), and covered with plastic wrap on top for 3-4 weeks before rooting.

Features of aster care

It is not difficult to grow it, it is an unpretentious plant and requires little attention, the main actions should be aimed at:

  • Watering. With periodic rains, additional watering is not even required, and especially if mulch is available. Watering with warm water is required only during dry periods, but the plant cannot be poured, watering should be moderate.
  • Weeding. For perennials, weeding is important, combined with loosening. It removes the crust on the soil surface, gives oxygen access to the roots and retains moisture in the soil.
  • Top dressing. Top dressing is carried out in the phase of the first 2-3 leaves, before planting seedlings in a pot or in open ground and during the appearance of buds. Complex fertilizers at a dosage of 25-40 mg / m2 are suitable for this purpose.
  • Division of the bush. The plant grows quickly and it is advisable to divide the shrubs into several parts once every few years. This is done in early spring. And once every 5-6 years, the soil of the flower garden is enriched and transferred to another place. Faded flower stalks are always cut off, and tall bushes are tied to a support.

Shelter for the winter is not required, all varieties are characterized by frost resistance. The exception is plants that were separated in the fall and did not have time to take root. To preserve the bush, a shelter in the form of sawdust or spruce branches is used.

Pest and disease control

Of the diseases, asters are most susceptible to:

  • powdery mildew;
  • rust;
  • verticillary wilting.

To avoid and get rid of them will help:

  • Correct agricultural technique.
  • The qualitative composition of the soil.
  • Treatment with special chemicals for disease control.

And the most common pests are:

  • aphid;
  • ticks;
  • slobbering penny;
  • acaricides.

From the appearance and to get rid of insects will help:

  • Compliance with the timing and distance of planting seedlings.
  • Digging a flower garden in the autumn.
  • Fertilization.
  • Removal of fading, dying parts.
  • Special chemical agents are protected from pests.

New Belgian aster in landscape design

This type of aster is ideal for decorating a plot. It quickly grows in large decorative "caps", against their background plants with large buds look good.

The bushes can be planted as hedges or fancy green sculptures. And designers are very fond of this view for the opportunity to decorate with it any unattractive corner on the site or in the garden.

Rarely do without asters and alpine slides, rockeries. There they occupy leading positions. Long and late flowering allows you to extend the life of the alpine slide until the very frost. Low-growing varieties are often used to frame or curb garden paths and flower beds. To do this, they are planted tightly in one row.

Plants of several colors are used to create more complex compositions, drawings, the main thing is to choose the right color combinations and then the result will be impressive.

Potted asters can decorate not only the garden, but also balconies and terraces. And florists make bright unusual bouquets from asters, varieties with terry baskets - inflorescences - look especially impressive.

The bouquets are not only beautiful, but also pleasantly scented, with a delicate sweet aroma.

A favorite area for gardeners is the cultivation of New Belgian asters (in other words, Sentbrinks) in flower pots. For these purposes, dwarf low-growing varieties 50 - 60 cm in height are best suited. Many annuals are combined with such bushes: marigolds, zinnias, kosmeya, nasturtium. Such a composition will decorate a terrace, veranda or balcony from spring to frost.

The New England Astra has more lush and spreading bushes, covered with small flowers, in contrast to the Novobelsk relative, and has many dwarf species.

Flowers that end the summer season with flowering are always memorable and pleasing to the eye even with the onset of frost. These cute shrubs carry a bit of summer warmth and sun, are resistant, and are suitable for growing outdoors and in flower pots on balconies and terraces.
