Japanese azalea has an attractive appearance, richly blooms and is well experiencing frosty winter in Russia. However, growing and care for it possesses some features.
Azalea Japanese is a fairly valuable rhododendron. “Pink Tree” becomes decoration of any site due to its luxurious appearance and pleasant aroma. In nature, this plant grows in Japan on herbaceous and well-lit mountain slopes. It lives for about 40 years, it reaches a height of a couple of meters, and in diameter is 1.2 meters. Although Azalia can be grown by itself, It works organically in various compositions.
During flowering, the bush is covered with a large number of bright-colored flowers, the palette of which varies from bright red to yellow. Buds appear not separately, but assembled in inflorescence with a number of 6 to 12 pieces. Their size allows you to fully hide sheet plates. Azalea sheets, by the way, are also quite large: their length is within 4 to 10 centimeters, and the width is from 2 to 4 centimeters. Skin of thin plates covered with bristles, and its color changes with dark green in the summer on yellow-red in the autumn season.
Fall azalea blooms about 2 months, and during this time it is revealed from 100 to 400 colors. It happens from May to the end of June. Shrub can be both reprehensive and flimsy. The color of shoots over the age of age is changing from green on brown. The roots lie shamefully, forming a basic system. Wood herself has a dense resin structure and gray bark. Seed material is formed in a fruit box.
Winter hardiness at the plant is quite acceptable – If we provide proper conditions and high-quality care, then Rhododendron can calmly cope with Russian cold.
Garden Japanese azalea has a lot of varieties. “Pettical” It is a half-green shrub, the height of which comes to 50 centimeters, and sometimes up to 90 centimeters to achieve the ten-year-old age. Tight crown in width is 90 centimeters. Oval bright green leaflets do not differ in large size. Flowers themselves with their form resemble peonies. Terry petals painted in bright pink-lilac shade.
Blooms “Pettical” in the late spring. For the winter, the variety requires additional protection against winds and precipitation.
Maruschka Grow up to 50 centimeters in height, and the diameter of the spreader crown ranges from 70 to 80 centimeters. Breast-red inflorescences please the owners throughout May. Flowers appear this size and in such a quantity that the leaves are almost becoming visible. However, plates grow small, shiny and tight. Throughout the summer season, they are painted in green, and in autumn become burgundy.
This grade has good frost resistance, but reacts poorly to drought, which means that the soil should always irrigate.
Other common varieties include Schneeperle, Purpurtum, “Vix Rosichered” and “Geisha Perf”.
Choosing a place to land, should take into account the climatic zone, in which Azalea Japanese has to dwell. For example, if the summer months are characterized by high temperatures and lack of precipitation, it is better to accommodate a bush in a scattered shade behind the house. If the climate is moderate, you can choose a more open area illuminated in a larger volume.
The soil for the Japanese Rhododendron should be either neutral or weakness. Otherwise, with insufficient acidity, the flowering of the bush will not be so abundant. The ideal is the place located next to the reservoir (both natural and artificial). In this case, Rhododendron will always be in the conditions of optimal humidity.
Ideally, it is necessary to connect the usual garden ground and the top layer of peat, after which it is possible to pour the resulting substance with a thickness of half the meter and shock with the Earth. In the event that under the area, groundwater proceeds close to the surface, it is necessary to further form a drain layer. The depth of the landing pit should be 50 centimeters, and the diameter is at least 70 centimeters.
Drainage in the form of a broken brick is placed on the bottom, traverse, sand and leaf land, taken in the 3: 1: 1 proportion, then you need to pour all the water.
You can not use lime crushed stone for drainage, as it causes soil deoxidation.
The seedlove itself falls into the water along with an earthen room until the air bubbles stop extinguish from the roots. It is done to moisten the soil. Root neck in this case does not plunge. The bush is immersed in the middle of the hole. The remaining place is filled with the substrate, the surface is compacted, irrigated and murdered.
Fertilizers starts through a couple of weeks after landing. It is more convenient to use mineral fertilizer complexes sold in specialized stores. From the organic, it is better to take a chevy that is used for mulching. The height of the mulch layer ideally is 5 centimeters.
It is strictly recommended to use ash, as it reduces soil acidity.
Fertilizer’s making stops in August when the plant begins to prepare for the winter period of rest. Optimal humidity for Japanese azalea ranges from 70 to 80%. This indicator is able to provide only automatic watering.
In the absence of the latter will have to spend spraying in the morning and in the evening. Irrigation itself should be abundant and carried out either daily or every other day. In winter, rhododendrons are able to withstand cold, reaching -26 degrees. Cover the plants still have to create protection against snowdrifts and bright winter sun. The twigs are neatly tied together, without damaging the kidneys.
During the perimeter of each plant, pegs are clogged, it is they fix the protective coating: burlap or polypropylene.
In addition to direct shelter, Rhododendron in winter will need and necessary moisturizing. To do this, somewhere since the beginning of the fall and up to frosts, the bush will have to water every 2 days, using approximately 12 liters of water. Then necessarily mulching with a pine bark. The mulch layer should be pretty thick.
As soon as cold come, the lower branches are recommended to sprinkle with a compost, peat or again a pine cheese.
Irrigation is carried out using a defined liquid. The top layer of the soil should be wet, but not too much so as not to provoke the rotation of the root system. If the earth will dry, the Azalea will begin to reset the sheets and inflorescences. Watering is also reduced at the end of summer. As for trimming, it is carried out through a couple of weeks after flowering.
The main purpose of the formation is to remove the boosted shoots and to break them.
When the reproduction is carried out With seedliness, Parts of plants are better to take the bush, which hesitates from 2 to 4 years. How exactly it is carried out, described above.
No less successful, the cultivation of seeds. The bush as a result grows up to 10-15 centimeters in height and perfectly carries out in the open soil. The procedure is carried out at the beginning of winter. The substrate will be required, the acidity of which ranges from 4.0 to 4.5, it is based on peat. For disinfection of the soil will need a strong heat transfer solution.
Seeds are deepened in the ground somewhere on 2 centimeters, after which the surface is irrigated and closes either by a plastic film or a glass sheet. At least for a couple of hours a day, the greenhouse will have to be transferred to ensure that. To successfully germinate seeds, you need to provide azaleas The temperature of 25 degrees of heat and humidity in borders from 75% to 80%. When the first shoots appear in a couple of weeks, the temperature will have to reduce to 10-12 degrees.
In addition, you will have to organize the right scattered lighting.
Diseases and pests
Most often, Japanese azalia attacks azali wane. Empty by it liquid covers the surface of the sheets, and the red mite and a sage mushroom occurs on it. The solution to this situation is carried out With the help of fungicides and melatonin. The first stop the development of fungus, and the second copes with the tool and other insects. Sometimes the red tick occurs if the plant is not irrigated enough, as a result of which the earth dries.
White plaque on the plate appears when Rhododendron is infected with a paw. Since the pest sucks the juices from the plant, the sheets after twist and dried. Get rid of the pest will help Preparations “Agrantin” and “Diazinon”. When a black trips shares on the plant, the leafles themselves are black. You can destroy it with help “Carboofos”.
If the flower petals were covered with black dots, this suggests that a rhododendron tick is affected by the Japanese Azalia.
Fungi affect the bush in cases where the temperature falls below the norm, and moisture, on the contrary, it turns out too high. Other common diseases include phytoofluorosis, chlorosis and fusarious wilt.
All these diseases are treated with special preparations. However, it is much better to carry out preventive processing.
At the beginning of the vegetative period, the plant is processed by copper chlorokis, as a result of which a thin film appears on the sheets, which prevents infection. Next bush it would be nice to spray “Fundazole”, which responds not only for prevention, but also for treating diseases in the early stages. Finally, the improvement of immunity plants is carried out by making nitrogen-containing fertilizers.
