Growing Rules
Planting and cultivating "Allium" does not cause much trouble for gardeners, but nevertheless, some rules of agricultural technology must be observed. Even the most unpretentious plant needs care, and decorative onions are no exception.
"Allium" belongs to light-loving crops, so the landing site should be open, sunny, without prolonged shading.
Onions respond well to soft loose soil, with good air access to the root system. It is optimal to provide drainage in order to eliminate the risk of stagnant water - prolonged waterlogging can quickly destroy the root system of a flower.
The acidity of the soil should be normal. Normally, the pH is 7. If this figure is significantly lower, then before planting the plant, it is necessary to carry out liming of the soil.
Planting seeds
Allium seeds should be planted in the ground in early autumn or early spring, as soon as the snow melts. With this method of reproduction, illumination is very important for a young plant - the place should be directly under the rays of sunlight. Keep in mind that in the first and even in the second year you will not see flowering - this will happen no earlier than after 3-6 years, when the bulbs become sufficiently large and strong.
Seed material is obtained after flowering. In order to grow a healthy plant, it is better to take seeds from the largest inflorescences, preferably the first ones. Collection is carried out only after the flowers are completely dry.
Some Allium varieties, especially tall ones, require seed stratification shortly before spring planting. In this case, it is possible to artificially spur natural natural processes and prepare the seeds in the best possible way for awakening and germination.
At home, this procedure is quite simple. To do this, the material is placed in a canvas bag filled with sand and put in the refrigerator for a couple of months.
If neglected, seed aging can cause them to rot in damp soil in the spring.
Vegetative method
If a healthy Allium bulb is planted in the ground, then in the third year of its development it will give strong shoots with arrows and, accordingly, will begin to bloom. A healthy flower usually forms 2-3 children. Autumn is considered the best period for vegetative propagation - it is at this time that the plant can be transplanted. It should be borne in mind that each bulb should deepen at a great distance between each other - only in this case the onion will grow throughout the area and decorate it with its beauty.
It is optimal to carry out planting at 10-12 degrees. As a rule, work is carried out in September - then, even before the onset of frost, the bulbs have time to take root and will bloom next summer.
The bulb is buried to a depth corresponding to 2 diameters of its own size, and then a piece of land is covered with peat or grass mulch.
Reproduction by bulbs
This is an unusual way of reproduction, which involves the use of biological products - growth stimulants. To do this, suitable buds are carefully cut and processed with a solution - this method is recommended in order to obtain an absolute copy of the mother flower.
Designers recommend planting "Allium" next to poppies and peonies - these plants bloom at about the same time, in addition, "fluffy" neighbors well mask the drying leaves of "Allium".
Feeding and watering
Planting plants does not present any difficulties, but for normal growth and development of flowers, it is necessary to properly care for it.
"Allium" refers to plants that do not require abundant watering. The culture can tolerate short-term lack of moisture without any unpleasant consequences.
If the root system is in constant waterlogging, then this leads to the most deplorable consequences for the bulbs - the rotting of the bulb and the death of the flower itself. The bushes experience the need for moderate watering only at the stage of active vegetation, at the time of the formation of peduncles and leaf mass.
In the future, irrigation work is carried out as the earthen coma dries up, and if the weather is rainy, then they are completely reduced to a minimum.
"Allium" responds well to the introduction of ash and rotted compost. Fertilization is best done at the stage of active plant growth and during flowering. In general, the feeding scheme looks like this:
- In the spring, at the stage of active vegetation, onions require the introduction of preparations containing nitrogen. It is best to purchase ready-made complexes of preparations in the nitrate form, they help stimulate the growth of green mass, the formation of young buds and the laying of bulbs.
- In the summer, you need to make liquid top dressing several times. It is optimal to use complex mineral compounds that can be bought at any gardening store.
- At the very beginning of autumn, the application of potassium-phosphorus fertilizers will be optimal, and preferably in a dry form - they will be able to prepare the plant for wintering.
- Before the first frost, the soil in which Allium grows should be mulched with peat or humus.
Diseases
Unfortunately, there are no plants resistant to pests. And "Allium", despite its decorative origin, is not protected from diseases characteristic of plants in our strip.
The most common cause of plant ailments is illiterate care and excessive moisture - this creates favorable conditions for the destructive activity of root mites, fungal diseases such as various types of rot, peronosporosis, and onion flies.
The best defense of the plant will be preventive measures that can prevent unpleasant phenomena. In order to protect the bulbs, they should be warmed up before planting at a temperature of 40-45 degrees for 10-13 hours. This can be done using a dryer or oven.
If the plant has become a victim of ticks, then it must be sprayed with a solution of 25% chlorophos, although many "in the old fashioned way" use folk remedies - ash, tobacco dust and peat.
Of the other Allium diseases, the following are most common:
- Tobacco thrips - small insects that suck the life juices from the leaves and stems of onions. To avoid "acquaintance" with such a scourge, it is necessary to maintain high humidity. To do this, it is recommended to regularly spray and water the plant with preparations such as Vertimek, Spintor or Aktara.
- Onion fly. This pest, as a rule, infects the bulbs of plants, while the leaves of the bushes begin to turn yellow, the roots rot and the plant dies. A good preventive measure against the fly would be early planting, and if the problem still could not be avoided, then it is worth treating the bush with Medvedtoks or Ratibor preparations, and irrigation with a solution of table salt has also proven itself.
- Downy mildew and neck rot - These are very common lesions that are successfully prevented if, after digging, simply dry the bulbs in the sun.
Transplant and storage
Decorative "Allium" requires periodic rejuvenation. To do this, every 4-5 years it should be transplanted. Some species require annual digging for the winter - such varietal features should be clarified when buying planting material. However, some experienced summer residents recommend digging up the bulbs of all Alliums planted in Central Russia, otherwise they can simply freeze out at very low temperatures.
Many cut off the green mass of onions after flowering - this is a common mistake. It must die naturally, only in this case the bulb will be able to accumulate and retain the greatest number of nutrients.
Bulbs should be dug up for the winter only after all the leaves and stems have dried up, after which they are cleaned of an earthen clod and dried naturally. Storage is carried out in a dry place at room temperature not exceeding 20 degrees.
The smallest bulbs are best placed in a ventilated container with sawdust or peat.
Is it possible to eat?
"Allium" is an ornamental horticultural crop, however, it can be eaten. However, mostly undersized varieties are suitable for this. The leaves have a sharp garlic smell and taste reminiscent of wild garlic, and contain a whole range of vitamins that have a beneficial effect on the body.
It should be borne in mind that the leaves are suitable for consumption only before flowering, after which it is highly not recommended to eat them.
Many also use bulbous plants, especially young ones.To do this, they are boiled with honey or baked. However, you should not get carried away with this process - like all other onions, in large quantities such a product can cause allergic reactions. The daily dosage should not exceed 3 g per day, otherwise the use of Allium leaves and greens can lead to a significant deterioration in health.
But in small doses, the plant is very useful for children and adults. It contains 4 times more vitamin C than its usual onion counterpart. The vitamins E and D present in the composition have a general tonic effect, strengthen the immune system and have a slight antitumor effect.
Varieties of ornamental onions successfully relieve spasms of cerebral vessels, have the most beneficial effect on visual acuity, and are also a good help in the fight against colds and gastrointestinal diseases.
Many people use Allium juice for cosmetic purposes - an extract of leaves and bulbs is rubbed into the scalp, which effectively affects the hair roots.
Application in garden design
The main purpose of a decorative bow is decorative. This is not surprising, given its exceptionally attractive appearance. All varieties are well combined with a wide variety of flowering plants, so they are widely used to decorate flower beds, flower beds, landscape gardening areas.
When combining plants, one should take into account the height of the arrow, the size of the inflorescence, its color, and most importantly, the period and duration of flowering. The bow looks very aesthetically pleasing in combination with roses, as well as geraniums, peonies, milkweed and irises.
Individual plantings of tall varieties look pretty good, and group clearings combining "Alliums" of different types look very interesting.
Due to their large spherical heads, Allium group plantings form a beautiful decorative carpet, the shades of which vary and can be light and dark purple, smoky pink, light blue and deep blue.
Group plantings are formed at the rate of 50 plants per 1 square meter. As a rule, undersized varieties are taken for this, the onion carpet of which stylishly sets off shrubs and small trees.
A lot of florists use onions to make bouquets. This is due not only to its decorative effect, but also to the ability to maintain a fresh look for 10-14 days. So that the characteristic aroma does not interfere with enjoying an unusual bouquet, you should often change the water and add a pinch of salt to it every time - in this case, the pungent smell will disappear.
Plants can be dried - in this case, they can delight with their exotic appearance for several months. To do this, cut arrows with flowers until the moment when seeds appear in them. The blanks should be dried separately from other winter bouquets, with each flower dried separately, otherwise there is a high risk of losing the natural shape. Drying plants is very easy - for this they are placed in a vase without adding water.
Growing ornamental onions is a simple process that does not require significant effort, time and money. Moreover, many flower growers consider the cultivation of "Allium" a fascinating procedure, thanks to which you can get beautiful and spectacular flowering balls.
