General rules for growing
Caring for this plant is not particularly difficult. Experts advise starting experiments with locally adapted nursery seedlings. However, even a minimal horticultural experience allows you to decide on an independent cultivation of this culture. It can be propagated both by seeds and cuttings. The cutting method is much more effective.
Cuttings are planted outdoors in the spring months. Only under this condition will their roots be finally formed and strengthened before the beginning of winter. To prepare planting material, use the tops of the plants. They must be cut off, leaving a small part of the old bark. An unnecessary amount of this bark is simply cut off.
When the cuttings are ready, they must be treated with growth stimulants and immediately transplanted into moist soil. A suitable substrate is made up of an equal amount of sand and peat. Cuttings should be planted at a slight angle.The used container is immediately rearranged where it is warm and light. The plantings are systematically sprayed from a spray bottle.
It usually takes 8 to 12 weeks to wait for the roots to appear. Then the bushes will develop rapidly. Transplanting to the place reserved for the bush must be done with an earthen clod in order to improve the development of the plant.
The landing site should be sunny, well protected from drafts.
In the first year of development, young seedlings should be properly protected from excessively bright sun. The landing pit is prepared in advance. It should be twice the size of the earthen lump along with the roots. The landing site must be drained, and a nutrient mixture for conifers should be laid there. If the soil is overly acidic, add some lime.
The junipers themselves are planted so that the root collar is at the level of the soil. Mulch from chips or pine bark is placed around the planting site. If you do not mulch the plantings, it will become more difficult to care for them, and the plants will lose their neat appearance. Humidity is not too critical, but it is still better to water the juniper systematically. Plants of the first year of development are watered as often as possible to speed up the establishment of the root system.
Normally, by the age of 10, blue junipers grow up to 2.5-3 m. It is necessary to protect these plants from such a dangerous ailment as rust. As soon as its first manifestations are noticed, diseased branches are removed, and the plants themselves are sprayed with synthetic preparations. Insecticides help fight aphids and miner moths.
