The horizontal juniper plant is a type of evergreen creeping plant. Its subspecies - Juniper Blue Chip - is a dense shrub with branches that are raised up.
This is juniper, whose growth rate is low. Needles Blue chip flake texture, silver-blue in the summer. In winter, this juniper changes its color and becomes purple, brown or purple. Upon reaching 10 years, its height becomes about 20 cm and a diameter of 150 cm.
Its natural habitat extends from Canada to the Atlantic region of the United States. Like all junipers, it belongs to the cypress family and is quite close to the Cossack juniper.
The fruits of the plant are spherical cone berries 5-6 mm in size, almost black. The main difference between the Blue chip variety is that it perfectly tolerates the gas contamination and smoke of the atmosphere, which makes it suitable and, most importantly, profitable for landing in a modern city. In addition, it by itself perfectly generates clean air and cleans everything around from various kinds of microbes at a distance of up to 10 m.
The Blue chip variety is not very picky about soils, however, for planting in open ground it is necessary to mulch. It takes root well on sandy and slightly acidic loamy soils, but does not like moisture stagnation. At the same time, it tolerates frosts and heat well, which is important for regions with a constant change in temperature conditions.
This juniper is recommended to be planted in sunny places or where there is partial shade. After extracting the plant from the container, before the direct planting process, it should be properly watered. The landing pit should be twice as large as the root system. To achieve good survival, it is necessary to replace the soil with a nutrient mixture. The latter is equal parts of sand, peat and turf land. Ready soil mix for conifers is also suitable, which must be mixed in equal parts with the soil for planting. This is not surprising, because the natural habitat of juniper is the sandy shores of reservoirs, for example, large lakes.
It will not be superfluous to add complex mineral fertilizer. Such a transitional layer will allow the roots to germinate better in the soil. Heavy soils and the presence of groundwater require drainage measures. Broken brick or gravel is suitable for organizing drainage. The layer height should be about 20 cm. During planting, the root neck of the blue chip juniper should be flush with the ground.
As such, shelter is not necessary, but in the early spring, when the sun begins to shine brighter, the young juniper can get a needles burn. To prevent this from happening, it must be shaded using agrofibre or fir spruce branches.
How does the bush propagate? Varietal forms are propagated with the help of spring cuttings, which must be taken from short side shoots. The shoots must be with the so-called heel, and they are taken before the kidneys are awakened or at the very beginning of their awakening. The rooting process begins at a temperature of 15-18 ° C, and then it rises to 20-23 ° C. Rooted half of the winter cuttings.
You can propagate the plant and layering, the rooting process in this case takes place a whole year. However, in this case, the usual shape of the crown cannot be maintained.
Juniper Blue Chip: Features of the variety
Watering and feeding
Juniper should be watered frequently during the first year of planting. This is necessary because the root system is still relatively small and compact, and is unable to fully and independently consume moisture and necessary substances from the soil.
Then the watering process is carried out 1-2 times a week. This is especially true for dry periods of the year and it is primarily necessary for still young plants. You should not forget about it, because losing a plant at such a time is quite simple.
So that the process of moisture evaporation does not occur so quickly, you can make mulching with wood chips or pine bark with a layer of 5-7 cm. In this case, you can water the plant much less often - only when the topsoil dries.
Spring feeding in the period from April to May is carried out by nitroammophos or with the help of complex mineral fertilizers.
In October, potash and phosphorus fertilizers are introduced. If the juniper is affected by fungal diseases, it should be treated with fungicides:
Shrub Disease Prevention
Even if the plant is healthy, preventative measures are periodically indicated. These include treatment with Bordeaux fluid 1%.
If the juniper has become an object of aggression by pests, such as aphids or caterpillars, it must be treated with insecticides. Quite effective drugs such as Actara or Confidor. Processing is carried out twice, the interval between such actions should not exceed a week or 10 days. Otherwise, negative processes can take an irreversible character.
This juniper is not specially cut. Only sanitary pruning may be required, which includes getting rid of dry, sick or improperly growing branches. It is produced in early spring.
How to plant juniper
Scope of application
The plant perfectly decorates borders and walls. It can be used as a living carpet, great for rock gardens. In addition, a good and powerful root system allows you to use this juniper to strengthen various slopes and slopes. It can also be planted on stony retaining walls. It’s not bad for decorative molding, and in urban conditions it’s also an excellent container culture.
