Among evergreen horticultural crops, a particular place is occupied by aurity. This flowering plant does not require specific care conditions, perfectly survives even on depleted soils and has small but numerous inflorescences of blue, purple, red and white flowers. In this material you will familiarize yourself with the description of popular species and varieties of shaving, as well as learn about the intricacies of growing this flower.
Aubrieta (or aubration) refers to perennial evergreen herbaceous plants from the cabbage family. This flower garden crop has a small height (up to 20 cm), as well as small inflorescences of pink, purple, white or azure. The leaves of the sheath are endowed with denticles or have a complete structure. The flowering period of this perennial takes place in 2 stages. The first, depending on the variety, occurs in late spring or summer, and the second in early or mid-September.
Today, this culture is actively grown precisely for decorative purposes and is often used in the creation of landscape design of gardens, loggias and summer cottages.
Overview of species and varieties
To date, scientists have identified about 17 independent species of shaving, but gardeners are actively using varietal diversity in just two of them: deltoid and cultural varieties. Below, we will consider the key features of these species, as well as the main varieties of aubration and their external characteristics.
This species includes undersized varieties (up to 15 cm) of obriet with racemose violet or lilac flowers up to 1 cm in diameter. The leaves are pale green, ovoid, with characteristic denticles. The variety is characterized by a long flowering period, which occurs at the beginning of summer or the end of spring.
This is one of the oldest types of aubriet - for the first time it began to be grown at the beginning of the XVIII century. It is from this species that all existing varieties of hybrid aubration were formed.
This hybrid group includes all hybrid varieties of this plant, which do not exceed a height of more than 20 cm and are characterized by excellent winter hardiness. In addition, this variety is characterized by small oblong leaves, which are slightly serrated at the edge . Flowers are distinguished by a large number of lilac or purple inflorescences with a diameter of up to 10 mm. The variety includes terry and standard varieties, as well as crops that can be grown both in open ground and in apartment conditions.
Gardeners include several names among the most common varietal crops of hybrid ubrit.
- Cascading. These plants have inflorescences of purple, pink, azure or red in color with a characteristic yellowish core. A distinctive feature of this variety is the preservation of the color of shoots and leaves throughout the year - even in winter these flowers retain their greenery. The variety can also be recognized by the gray-green leaf plates.
- "Cote d'Azur". The peculiarity of this variety is a long flowering period, which lasts during the first two summer months, and then lasts from mid-September until the onset of winter frosts.
The variety got such a name due to the azure or heavenly shade of small flowers. The leaves of this plant are also small, light green in color.
- "Enchanting Morocco." Unlike other varieties, this plant has lush buds of saturated red, blue or pinkish color. A distinctive feature are large flowers up to 1.5 cm in diameter. The color of the leaves is light green.
- "Purple Cascade." This variety of shaving is distinguished by small oblong leaves with denticles along the rim, as well as small purple inflorescences up to 10 mm in diameter. The variety is popular due to the large number of bright flowers, as well as the long flowering period (1.5 months), which begins in May. This flower prefers open sunny areas with neutral, depleted and light soils and good water conductivity. In the autumn, flowering resumes and continues until frost.
- Campbell. A lush, low-growing plant (up to 10 cm) with large purple or azure inflorescences up to 1.5 cm in diameter. The flowering period also occurs in May and lasts about 1-1.5 months, then resumes in the fall.
It is with the help of this variety that garden paths and borders are decorated.
- "Giant waterfall." It is a mix of different varieties of obriete, which is distinguished by purple, pink or burgundy flowers up to 1 cm in diameter. Includes fairly tall plants that can grow up to 15 cm in height. In addition to external qualities, such flowers are characterized by excellent frost resistance, which allows them to bloom even in the conditions of autumn frosts.
With this mixture of aubration colors, gardeners often decorate single flower beds, garden paths, or curbs.
- "Blue Cascade." One of the most popular and magnificent varieties in the decoration of large flower beds or rock gardens. It is characterized by numerous flowers of dark blue color with a yellowish or white core. The maximum height of the bushes is up to 15 cm.
Rules for boarding and transplanting
Even an inexperienced gardener can cope with the planting of a shade - this is an extremely undemanding and simple flower when it comes to planting in open ground. Below, we will consider the intricacies of planting seedlings and seeds of aubration, as well as the features of transplanting this garden culture.
Planting seedlings in open ground
Gardeners prefer to plant seedlings in April or May, when long spring frosts have already passed. For planting, an open and well-lit place is chosen from the north side of the garden.
For the plant, both fertile and depleted soil is suitable - in this sense, the sheaf is absolutely not picky. The main condition for the type of soil - there must be good air and water conduction, so ash, sand and peat are added to heavy soils with a high clay content, which allow water to be more effectively absorbed and not linger at the roots of the plant. As for the composition of the soil, neutral or slightly acidic soils are suitable for the growth of a healthy and plentifully flowering shade.
The further process of planting the shaving in the garden includes several stages.
- Before planting seedlings, containers with seedlings are lowered into the water. When oxygen bubbles appear on the surface of the pot, the plant is gently pulled out and installed by transshipment into the prepared hole in the area.
- The depth of the hole should be selected based on the age of the seedling and the size of its root system. In width, it should be slightly larger than the size of an earthen coma from the mother's capacity.
- A drainage layer is organized at the bottom of the hole, after which the sapling together with an earthen lump is placed on top of it, and the formed holes are filled with fertile soil from peat, meadow land and sand. After filling the holes with soil, the soil in the near-stem circle is compacted and watered, a layer of mulch is organized.
Already experienced gardeners prefer to plant not shaved seedlings in open ground, namely seeds. Before such planting, the soil at the landing site is subjected to special treatment.
- Soil at the landing site is dug up to a depth of 15 cm, while all weeds, old roots and stones are removed from the soil.
- Fertilizing in the form of lime or ash is introduced into the ground. Then the soil is carefully dug up and moistened so that the fertilizer is absorbed.
- Seeds are planted directly on the surface of the earth with a preservation of a distance of 7-10 cm. Seeds can be pressed a little, and then be sure to sprinkle with a layer of fine sand 3-5 cm thick.
- The site is abundantly watered with a spray or watering can.
- If you planted seeds in a warm spring and provide regular watering, then the first sprouts of shaving should appear after 2-3 weeks. When sowing seeds for the winter of the first sprouts, wait no earlier than next spring.
You can transplant the Aubriet to another place in three cases:
- during propagation by separation of the bush;
- with the growth of a maternal adult bush;
- as well as in the case of buying a plant in a gardening store.
It is worth saying that the obrietus is not particularly good at transplanting - in most cases, the transplanted plants take root in a new hole for a long time or wilt. It is for this reason that picking this garden plant is undesirable, and planting seeds for seedlings is carried out in separate pots, rather than large containers.
Usually, aubration transplantation is performed no more than 1 time in 2 years in the case when the container with the plant ceases to contain its roots. When growing aubration in the garden, this can be seen by the root shoot, which will be knocked to the surface of the earth.
The procedure itself is carried out in the spring, before the period of active growth and flowering. In order for the plant to take root in a new plot faster, the same substrate is placed in the hole, and at the place of planting, a temperature identical to the temperature of cultivation in the last place should be observed.
After planting, the flower is abundantly watered and potash top dressing is applied to the soil.
Aubrieta is appreciated among gardeners not only for its beauty, but also for its unpretentiousness to the conditions of planting and growing on a flower bed and at home. This is a relatively self-sufficient plant that does not need regular watering, dispenses well with top dressing and loves to grow on infertile soils.
The intensity of irrigation irrigation varies greatly depending on the age of the plant and external climatic conditions. For example, if a summer resident has an adult and developed plant at his disposal, then it will need watering only in the summer season when the soil dries in the near-stem circle of the plant. Young plants and only planted abrections need frequent watering until they have their own root system.
In regions with regular and frequent rains, additional shaving is not needed - with excess moisture and a favorable temperature, the number of leaf plates increases and the number of buds decreases.
To prevent moisture from stagnating in the roots of the shrubbery, a drainage layer is organized in the holes for planting.
Most varieties of obriet are freely grown in summer cottages and without additional fertilizing. To extend the flowering period or stimulate the appearance of inflorescences, potash fertilizers are applied to the soil 2 times a season. Feeding is recommended only for adults or already grown shrubs. The best time for feeding is considered the beginning of the flowering period - to stimulate the growth of flowers, and the period after the pruning procedure - for a painless wintering.
In general, aubretions grow very well on poor soils, and therefore do not need complex feeding. It is believed that it is best to choose mineral or potash fertilizers for top dressing these flowers - she doesn’t like top dressing with nitrogen.
According to gardeners, wood ash is the best way to feed this garden crop.
Pruning is a completely natural process when it comes to cultivating an auburn. There are 2 types of pruning aubration: wellness and decorative. In the first case, the plant is cut every spring after the flowering period - all shoots of the plant are cut almost to ground level. This will give growth to new green shoots and will lead to repeated flowering in the fall.
Decorative pruning involves the regular removal of dried and withered shoots, leaves or inflorescences. This not only improves the appearance of the hair, but also directs the juices to the development of young shoots and the appearance of new flowers.
Some gardeners prefer to trim their shaving for winter, but this procedure is optional. This plant does not take off foliage with the onset of frost and can tolerate even prolonged frosts.
Experts advise sheltering such flowers for the winter, in order to prevent damage to the appearance of aubration and rotting shoots. Best for shelter suitable spruce branches, fallen leaves or straw.
Gardeners who cultivate auburn in open ground usually use only 3 methods of propagation of this flower: cuttings, dividing the bush and growing from seeds. Each of these methods should be considered in more detail.
Propagation of shaving with the help of cuttings is today considered the most popular. During summer pruning (after the first flowering), a large number of strong and green shoots without inflorescences remain on the plant, which can be used for planting.
When planting cuttings in open ground, it is advised to build a special greenhouse, as well as prepare a substrate of peat and sand. In the greenhouse, plants are regularly watered, and the condensate formed on the walls is removed - so as not to get on the leaves and not burn them.
Cuttings usually planted in a permanent place as soon as they acquire their own roots.
If in your region there is a cold autumn and a little snowy winter, then it is better to leave the cuttings in the greenhouse until the next spring - this will allow them to grow stronger and develop a more powerful root system.
Dividing the bush
Dividing the shade of the shrub is a rather complicated method that not every gardener can handle. The fact is that this plant tolerates this procedure problematically, and the divided bushes do not always take root in a new place.
Aubration bush division can be carried out both in spring and autumn, and involves a certain sequence of actions.
- The bush of auria is dug up and cleared of the ground, then divided into approximately the same small shoots with their own leaves and developed roots.
- If the root lump is too confusing and cannot be untangled, it should be separated using a sanitized pruner.
- All cut off parts of the shoots are treated with wood ash, and the roots with a solution for root formation.
- Separated young bushes are planted in separate holes at a distance of at least 10 cm from each other in accordance with the standard procedure for planting shaved. Before the bushes take root, they are provided with regular watering and top dressing.
Propagation of shaving with the help of seeds is not so popular among gardeners - everything is explained by the high time spent on this procedure, as well as the high probability of losing varietal properties of young plants.
To collect seeds for planting, during the summer pruning, several shoots with ovaries on the bush are preserved. After the pods themselves darken and dry, they should be cut, then husked planting material. Before planting seeds in open ground, they should be placed in a warm and shaded place and dried well, and also ventilated.
Shaved seeds are usually shaved at the end of winter (ideally in mid-February). Peat containers with drainage holes (pots) will be the best place to land. The following procedure for planting seeds at home will include several steps.
- For planting, you should choose fertile soil from a mixture of peat and sand in a ratio of 1 to 1.
- Before planting seeds, the soil is abundantly moistened, and drainage is organized.
- Up to 2-3 seeds are planted in one pot, which are evenly spread out over the container and slightly sprinkled with sand. Then the soil is moistened again.
- To create a pleasant microclimate, containers are covered with glass / plastic jars or glass / cellophane film. So that the air in the containers does not stagnate, they are sometimes aired.
- In a room with seeds, the room temperature should be maintained at not lower than +18 degrees Celsius.
- When the first shoots appear, the shelter in the form of a film is removed, and the number of waterings is reduced. During watering, you must try not to damage the fragile seedlings and not to get water on the leaves.
- Picking these plants is undesirable, but can be carried out after the appearance of 2-3 full leaves in seedlings. The landing in the open ground is carried out at the end of next spring.
- Before planting seedlings in a new place, the site is fertilized with mineral fertilizers and organic matter.
Diseases and Pests
Aubrieta belongs to a few garden crops that have a very strong immunity and are able to independently cope with most of the fungal and viral diseases.
In rare cases, signs of powdery mildew , a fungal disease, which manifests itself in the appearance of a white coating on the shoots and flowers of a plant, which grows gray over time, can be seen on aubration . The disease not only worsens the appearance of the flower, but also reduces its immunity. Without timely treatment, the sheath will fade and blacken.
The best way to combat this ailment is to treat the plant bush with a solution of colloidal sulfur. If the infection has gone too far, all painful shoots are cut off.
The most dangerous enemy for shaving is ordinary aphid. This pest is easily recognized by the huge colonies that settle on the shoots and leaves of the plant. Additional signs are: an increase in the number of ants near the plant, the formation of a light and sticky coating on the shoots, dark spraying on the leaves, dried flowers and shoots. Aphid not only weakens the shaving and sucks out all the juices from the leaves, but can also become a carrier of dangerous viral diseases.
Insecticides like Fufanon, Fitoverma, Intavira or Karbofos will help you in the fight against these pests. In addition, plants infected with aphids can be treated with warm water.
Another pest that can infect the auspices or weaken its immunity is the so-called cruciferous flea. A sign of the appearance of these pests are numerous dark holes in the leaf plates of flowers. The larvae of this pest can be removed manually, in addition, it really does not like water and does not take root in areas where calendula, garlic, marigolds or caraway seeds are planted.
To help aubration cope with these pests, the plant is fertilized with organic or nitrate.
Below is a short list of tips that will help you when planting and growing aubration.
- Aubrieta feels great in direct sunlight, however, she does not like the strong and cold wind. Gardeners recommend planting this perennial plant near a brick wall, fence or extension, which would protect aubration from sudden gusts of wind.
- Try to regularly maintain a favorable level of humidity in the near-stem circumference. This plant does not tolerate moisture congestion, but it will not be able to please you with abundant flowering in dry soil.
- Watering is carried out in the morning or in the evening to avoid contact with wet leaves and roots of sunlight. Water should be watered with settled water - after watering, the soil near the bush must be loosened and cleaned of weeds. To preserve moisture for a longer period, a layer of mulch (2-3 cm) of straw, pine needles, bark or rotted manure is organized near the abortion.
