Juniper scaly Blue Star is a coniferous plant that began to spread in the 50s – 60s of the last century. This dwarf shrub is not more than 1 m in height and up to 2 m in width. For 1 year shoots are extended by only 2-10 cm, so the plant reaches its maximum size only after several decades.
At 10-15 years of age, the maximum height of the shrub is about 40 cm.
The crown of a juniper has an irregular wide-oval shape, in appearance it resembles a crumpled pillow. The needles of young shoots are colored in greyish-turquoise hues; with age, this shade is replaced by a calmer blue-gray, silver color. Thorny lanceolate needles are small and arranged very closely to each other.

Even with a slight shading, shoots may begin to stretch, so that the shrub will look untidy, and the needles will begin to change shade from blue to a nondescript dark green - and the plant will lose its decorative qualities.
Juniper does not tolerate overwetted alkaline soils, therefore, such plants should be planted in soils with an acidity of about 4.5-6.5 pH. If the area is clay, then you need to add sand and peat. And if sandy, then humus and clay.
When planting a seedling, you must follow this algorithm:
- soak the soil in the container with moisture,
- dig a hole about 70 cm deep and several times larger in volume than the diameter of an earthy seedling;
- put a drainage layer at the bottom of the pit 20 cm,
- pull out a sapling together with a lump of earth from the container and place it in the center of the pit so that the root neck is 5-10 cm above the soil surface (after watering and subsidence of the ground it will be flush with the edge of the pit),
- fill the pit with a mixture of peat, sand and sod land, taken in a ratio of 2: 1: 1,
- pour the soil and lightly tamp,
- grind the soil with a layer of 5-8 cm.
When planting several seedlings, a distance of at least 50 cm must be left between the plants.
This juniper variety is quite unpretentious. It is drought-resistant, can withstand temperatures down to -25 o C, undemanding to the soil. However, in order to preserve the decorative properties, it needs certain conditions.
- Regular watering. During the first week after planting the seedling in open ground, it should be watered abundantly, and after this time - once every 1-2 weeks. Per 1 adult plant requires about 10-30 liters of water (the exact amount depends on the type of soil).
- Spraying or sprinkling shoots in the evening, especially on hot and dry summer days.
- Periodic renewal of the layer of mulch, which prevents the appearance of weeds, nourishes the soil and retains moisture in it.
- Fertilization. Nutrients must be made once a year in spring.
- Sanitary trim in the spring.
- Shelter and tying shoots with a string for the winter. In October, November, young plants should be covered with spruce leaves, and adults should be covered with a peat layer of 10 cm - this will prevent freezing of the shoots.

Young plants are especially susceptible to pests and diseases, and with age, resistance to these diseases increases. To prevent their occurrence, it is necessary to use only healthy planting material, promptly remove dried shoots, and apply fertilizer in time. Also effective will be the use of immunostimulants that increase the resistance of plants to unfavorable environmental factors, as well as various fungicides and insecticides.
The best way of propagation of conifers is cutting.
- In adult plants, a one-year-old shoot escapes from the “heel,” that is, last year's wood.
- The lower part of the cutting is cleared of needles and placed for some time in a solution of growth stimulant.
- The cutting is buried in a wet mixture of peat and sand.
- Top covered with foil or plastic bottle.
- After 4-6 weeks at a temperature of about 20 ° C, the root system develops. After that, the seedling is planted in open ground.

To shrub was lush, you need to pay attention to its feeding, which is as follows:
- The beginning of May - the introduction of the mineral complex.
- October - nutrition with potash phosphate fertilizer.
Also, the care includes loosening the soil and removing weeds.
Prepare the plant for the winter is easy. Adult plants do not need to comply with special measures, and young bushes are tied with string and covered with spruce branches. To protect the root system, including the adult juniper, it is necessary in November to fill it with a layer of peat about 10 cm tall.
In the spring, the plant should be examined, remove all dried and dead branches. Since the Blue Star flake juniper is characterized by a slow growth rate, it does not need constant crown formation, therefore keeping it neat is pretty simple.
