Although there are many methods of breeding asters, more often they are still grown through seeds. In particular, this method is recommended for the reproduction of alpine asters. Sow seeds for seedlings in March. If there is no desire to grow seedlings, you can immediately sow them in the open ground. In the southern regions this is done at the beginning of April, in the middle regions by mid-April, and in the northern regions - closer to May.

Important! If, after sowing the seeds, return frost began, the land on the landings well mulch or cover with a film so that the seeds do not freeze out.
Sow perennial asters best in loamy land. The sandy land, as well as heavy, clay, is not suitable for them, because in the first case, there will always be a lack of water, and in the second - there will be too much of it. Asters give a rich flowering solely on sunny terrain, while in the shade more lush foliage is obtained. It is also worth mentioning that tall perennial asters are afraid of drafts.
As for the sowing method, there is nothing difficult here. Asters sow with rare goose in the furrow to a depth of 3 cm. After sowing, it is necessary to make sure that the air temperature is about +15 degrees, then shoots will appear faster.
How else do perennial asters reproduce?
In addition to seeds, perennial asters can be propagated by cuttings, dividing the bush and vertical layers. Since it is difficult to check the cultivar in the market, and sellers often fail in stores, these methods are used mainly when there is a mother plant of the desired variety on its own plot or with friends.
For this method, it is necessary to cut the shoots up to 15 cm long. Always young pagons are taken. The lower cut is made oblique, all the lower leaves are cut, only the green tip remains. Then the lower part of the cuttings (2-3 cm) is immersed in a solution of growth stimulant or plain water for 10-12 hours - you can simply put it in a glass.
It is important! Putting the cuttings on the street immediately is not recommended. It is better to make a small greenhouse or carry out the procedure at home, in a deep pot.
When it takes 12 hours, you can plant cuttings. To do this, take a large pot or other container and there is filled up the nutrient substrate. Planted cuttings with a slope and immediately watered after planting. They keep sprouts in a lit place at a temperature of + 22 ... +25 degrees Celsius. In about a month, the cuttings will take root, and they can be planted in a permanent place.
This method is used very rarely, because it is long and troublesome. First you need to cut the bush in the spring at the root, fertilize and completely cover the ground. When young shoots appear, it is worth waiting for one month and then again filling the pagons with earth. In the fall or next year, in spring, the stems are cut off by 2-3 buds and planted where necessary.
The division of the bush.
This method is used when you need to transplant perennial asters to a new location or simply update it. The procedure is carried out every 4-5 years. To carry out the division, it is necessary to dig a bush, clean the roots from the ground (main), and then use the shears to separate parts of the young roots with shoots. Separation places must be powdered with wood ash. And all the resulting bushes are planted on the site.
Interesting! In the spring, only late varieties of perennial aster are propagated by dividing the bush, and early ones in the fall.

Perennial aster - one of the most unpretentious flowers in the flowerbed. Many gardeners and gardeners planting this plant, generally forget about it, only occasionally watering and pruning old pagons. However, if there is a goal to get a lot of lush flowers, then there will have to be some effort.
The land around the asters should always be loose, so that the root system has enough oxygen.
Weed plants should be destroyed as they appear. In addition, it is impossible to plant other cultures very closely so that they do not “clog” the land around, otherwise asters simply will not develop as much. So the distance between the aster and other colors should be at least 20 cm.
In order to grow fewer weeds, and it was not necessary to water very often, you can mulch the ground around the flower.
Perennial asters are watered about once a week or one and a half. Of course, this is an average indicator, depending on the climate, the amount of precipitation and even the level of groundwater, this figure may vary.
Top dressing is done 3 times per season. In May, it is necessary to make mineral fertilizers, dry or mixed with water, for flowers (with an abundance of nitrogen). During budding make potassium phosphate substances. When the first flowers appear, asters are watered with a solution of potash fertilizers.
Important! Any dressing is carried out only after watering, otherwise the roots can get burned!
Bush and undersized perennial asters are desirable to cut from time to time, otherwise the decorativeness of the bush will decrease significantly. The procedure is carried out in the fall, winter or early spring.
Tall asters are advisable to tie up or even grow at some large support. This will make growth easier for the plant and will simplify cultivation for the gardener.
For the winter, perennial asters are cut to the root. Top ground compost or fallen leaves. If we are talking about a young Astra, which is only planted, then we can make additional warming in the form of a thicker layer of mulch, which is covered with agrofiber or sacking.
Diseases and pests
Flowers disease and pests love no less than vegetables. They destroy the leaves of the plant, the pagon, the root system, can spoil the buds, so you need to make sure that they are not on the flowerbed. Perennial asters most often suffer from Fusarium and powdery mildew. How to deal with them?
Powdery mildew, which appears as white bloom on leaves and stems, can destroy the plant in a few years if it is not lime. For prevention, a simple soap solution is used, and for the fight against the disease - any specialized chemical preparations that contain a lot of sulfur.
There is no treatment for fusarium. Unfortunately, the affected plants have to be completely dug out and burned so that the disease does not spread to other cultures. The first symptoms of the disease are yellow leaves, stalk thinning, root rot.
Important! Popular recipes for diseases and pests should be used only for prevention or in the early stages, when the problem has just appeared.
Of the pests, asters most love the spider mite and the leaf nematode. When a spider mite appears, a thin web sprouts around the plant, black and white dots appear on the back of the leaf. In the case of nematodes, brown spots are formed on the leaves, they become thin, can bend, dry out or rot. To combat them, you should buy a good insecticide of systemic or contact action.
