Decorative bows - Alliums, are very diverse and are able to decorate any garden with bright balls of their inflorescences. Unpretentious bulbous plants begin to bloom in late spring and “freeze” for a long time at the peak of beauty. And even after the end of flowering, during the ripening of the seeds, the drying heads of decorative onions look very attractive.

Description of decorative bow

Ornamental onions are close relatives of the common edible onion and garlic and are part of the Alliaceae subfamily of the Amaryllidaceae family. If you rub a leaf, stem or bulb of any plant from this family, you will get an easily recognizable "onion" or "garlic" smell. In nature, there are several hundred species of onions that grow in the northern hemisphere.

Linear or belt-like leaves of basal onions. Each onion flower is very small in size, but the flowers are combined into an inflorescence, which gives the plant the main decorative effect.

Some ornamental bows can be as large as 30 cm in diameter, such as Christof's Onion (Allium cristophii). Most ornamental onions flower in May-June, but there are also autumn-flowering varieties. The flowering of some species can last for a long time and even after its end the plant will not lose its attractive appearance. So, dried balls of inflorescences of Christof's decorative bow look no less charming in an autumn garden than bright purple ones in a spring.

Features of growing decorative onions

Location: most of the onions are photophilous, so sunny areas and southern slopes with well-drained, loose fertile soils are chosen for them. The best illumination determines the color intensity of flowers and leaves.

Soil: A close to neutral soil solution is preferred. At a pH below 5, the soil must be limed.

Fertilizers: When preparing a plot for planting onions, the soil is filled with rotted compost and a complete mineral fertilizer with trace elements is applied, based on the indicators of its fertility. Like all bulbous plants, ornamental onions are very sensitive to potassium deficiencies in the soil. An excellent potash fertilizer for them is wood ash.

Watering: Bows tolerate both short-term drought and short-term waterlogging well. Sufficient moisture supply is a necessary condition for the normal development of plants in the first half of the growing season, when the formation of leaf apparatus and flowering shoots occurs. With a lack of moisture, the growth of leaves stops and resumes again when watering.

Ornamental bow care

When growing ornamental species of the genus Allium in a temperate zone, it is best to dig up the bulbs annually after the seeds have ripened and the leaves have dried up and replant them in the fall.

The fact is that ephemeroid onions and many xerophytic bulbous species originate from the middle belt of the mountains of Central Asia - an area with hot dry summers and winters with frequent thaws. At home, after the end of the growing season at the end of June, the bulbs of these species remain in warm, dry ground until autumn. There is practically no rain during this period.

In central Russia, if the second half of summer is damp and cool, the bulbs left in the ground can be affected by diseases and rot. Therefore, it is better to dig them up, dry them well and store them at room temperature in a dry, ventilated room until autumn. In areas with favorable environmental conditions, the bulbs can not be dug out every year, but when the plants thicken, they become smaller and bloom worse.

In autumn, the bulbs are planted after a steady drop in soil and air temperature, usually in the third decade of September. The optimum soil temperature for the rooting of the bulbs is at the level of 10 ° C in the root formation zone. The planting depth of the bulbs is determined so that above its upper point there is a layer of earth equal to three heights of the bulb itself. Accordingly, large bulbs are planted much deeper than small ones.

It is better to plant in a moistened groove, on top of the planting they are mulched with humus or peat, which should prevent the formation of a soil crust. In autumn, root growth continues until the temperature of the soil in the zone of their occurrence drops to +2.. + 3 ° С. Some types of bulbs - moth, Ostrovsky, pink, blue, blue-blue - can be planted in autumn and spring after storage in a cool dry place. It is better to store small onions in peat or sawdust to prevent them from drying out.

Bulbous-rhizome species are grown in a perennial culture and reproduce by dividing the bushes. Plants are transplanted after 3-5 years, sometimes even after 7 years, but in this case the planting must be thinned out and self-seeding must be prevented.

The optimal planting time is early spring and late summer, with the expectation that the divisions take root well before frost.

Each spring, the site should be deeply loosened, cleaned of plant debris and snow mold. Plant care during the growing season is usual - weeding, loosening and mulching the soil.

Plants are watered only when there is a clear lack of moisture, they must be fed in the spring after the regrowth of the leaves, as well as in the budding and bulb formation phase and at the end of summer with phosphorus-potassium fertilizers to improve the overwintering of plants. For spring top dressing, complex mineral fertilizers (NPKMg) with microelements are used, selecting forms with a high nitrogen content in the nitrate form.

In the summer, liquid fertilizing is carried out with a solution of mineral fertilizers. When feeding in August, granulated phosphorus-potassium fertilizers are applied dry. For the winter, plantings can be mulched with peat or humus.

Reproduction of decorative bow

The onion is propagated by seeds and vegetatively.

Seeds are sown in spring or fall. Seedlings dive into well-lit ridges. There are two important points to keep in mind when propagating by seed. Firstly, the seeds of many species, for example, xerophytic ephemeroids - giant onions, aflatunsky, stalked onions, etc. - germinate only with podzimny sowing, after exposure to the seeds of a complex of conditions of the autumn-winter-spring season. It is not even always possible to replace it with the same shelf life of seeds in the refrigerator.

And secondly, when grown from seeds, many types of onions - anzura, wild garlic, etc. - bloom in the 3rd to 8th year, only after the bulbs have reached a mass sufficient for reproductive development. The longest juvenile stage is characteristic of ephemeroid onion species with a short annual growing season.

The vegetative propagation of bulbous species occurs during the branching (division) of the bulbs and the formation of baby bulbs developing on the bottom and stolons of the mother bulb. The degree of branching of the bulb and the ability to form babies are species characteristics. Rhizome species, characterized by active branching of shoots, reproduce mainly by dividing the bush.

When growing plants from seeds, bushes can be divided from the third year of life. Delenki represent areas of rhizomes with two or three intact shoots and well-developed roots. In all species, small onions - bulbs can form on inflorescences. Their formation can be stimulated by artificial cutting of buds and treatment with growth regulators. Bubbles can be used for planting. This is a valuable, stage-by-stage planting material free from phytopathogens.

The use of decorative bows in design

Decorative onions are used in group plantings, mixborders, undersized species - on rocky hills. Cut ornamental bows decorate the interior for a long time, almost for 2 weeks, and dried plants can be used for dry bouquets. From onions, you can create a garden of continuous flowering.
