Instructions for growing juniper Gray Oul
Due to its unpretentious nature, juniper Virginia "Gray Oul" successfully takes root in rather harsh climatic conditions, on any soil, regardless of the degree of illumination of the site.
Meanwhile, this coniferous shrub can fully show its decorative qualities, being planted taking into account its preferences.
Adhering to agrotechnical guidelines for planting Gray Oul juniper seedlings and caring for mature bushes will help you grow lush juniper bushes in your garden without any problems.
Preparation for planting seedlings in open ground
The quality of the planting material directly affects the success of the entire process of growing juniper bushes. Seedlings should be purchased only from trusted manufacturers or sellers.
Before buying, you need to inspect young bushes. Shoots should not be damaged or show signs of disease, and there should be no wounds or rotten processes on the roots. The root system must be sufficiently formed - otherwise, the chances that the plant will take root in a new place are significantly reduced.
The needles of a healthy seedling usually have a rich color and do not crumble. The youngest of the already formed seedlings should be chosen. After all, the younger the bush, the faster it adapts to new conditions for itself.
Seedlings can be sold both in containers with soil, there and with open roots. You should know that in the first case, planting in open ground can be carried out throughout the season, and in the second - in spring or autumn.
As a rule, seedlings with a closed root system take root without problems after transplanting. The soil in the area set aside for juniper planting must also be prepared in advance.
Adult juniper bushes do not tolerate the transplanting procedure well, so it is better to immediately choose a place where they will grow throughout their life. On average, a juniper can thrive in the same location for half a century.
It should be borne in mind that the root system will grow as the shrub develops. Therefore, the site for planting it should be quite spacious. In order for the Gray Oul juniper to show its decorative qualities in all its glory, it is best to plant it in sunny areas, because in the shade its needles fade, and the crown loses its attractive appearance.
Stagnant moisture is extremely undesirable for Virginia juniper, therefore it is recommended to avoid areas with a high groundwater level relative to the earth's surface. Otherwise, there is a high probability of decay of the root system of the juniper and its subsequent death.
You should also take care of soil drainage. Juniper "Gray Oul" prefers sandy loam and loamy soils, but will take root on clay soil. To do this, it is necessary to facilitate it by introducing peat or river sand.
The procedure for planting juniper seedlings in open ground
After completing the preparatory procedures, you can start planting juniper seedlings in open ground. This must be done carefully so as not to destroy the earthen lump around the root system of a young plant.
The diameter of the planting hole should be twice the diameter of the coma. At the bottom of the recess, a drainage layer about 15 cm thick should be placed, consisting of expanded clay, pebbles, brick fragments. Next, a nutritious soil mixture is poured, prepared from soil and complex mineral dressings.
The seedling is placed on top of these layers so that its root collar is at the level of the soil surface. Then you should fill the hole in layers, simultaneously tamping each of them so that an air cushion does not form.
The topsoil should also be compacted and thoroughly moistened. Having made the decision to place several juniper saplings of the "Gray Oul" variety on one site at once, it is necessary to do this, keeping an interval of at least 3 m between the planting pits.
Otherwise, the overgrown shrub roots will be cramped.They will fight for space, nutrients and water. The most common mistakes that are dangerous to the health of young juniper bushes are:
- damage to the clod of earth formed around the root system of the seedling. It is fraught with a slowdown in the rate of its growth and development. In addition, the chance of successful adaptation to a new place decreases;
- too small a planting pit will not allow the roots of the seedling to quickly take root after transplanting and grow;
- placing the root collar of the bush below ground level will also lead to delays in its development and further death.
Care for juniper virgin "Gray Oul" consists of infrequent watering, fertilization, loosening and weeding of the soil, as well as pruning and forming the crown.
Irrigation and fertilization mode
Drought is not terrible for the juniper bushes of the "Gray Oul" variety, therefore it is recommended to water them no more than 2-3 times during the season, only in the hottest periods. Water consumption for 1 adult bush is about 2 buckets. It will not be superfluous to carry out the crown sprinkling procedure every week.
This should be done in the evening, after sunset. Top dressing is recommended to be applied twice during the season - in spring and autumn.
Spring feeding should contain a large percentage of nitrogen and other substances that will help the plant wake up and start active growth of shoots. For this purpose, you can use nitroammofosku.
Autumn fertilizers are intended to form the supply of nutrients needed by juniper bushes for successful wintering. Therefore, in the fall, the introduction of dressings with a high content of potassium and phosphorus is indicated.
To avoid burns to the root system, fertilization should be combined with the irrigation procedure.
Soil care in the area with juniper
It is important to regularly saturate the soil in the area with juniper bushes with oxygen. Therefore, it is necessary to loosen it after each watering. Otherwise, its upper layers will be compacted to form a hard crust that does not allow air to pass through, which will negatively affect the state of the root system and the entire bush as a whole.
Mulching will save moisture in the soil. In addition, this procedure will reduce the number of weeding, prevent overheating and freezing of the roots, and also act as an organic fertilizer. You can form a layer of mulch from sawdust, peat, pine needles.
Juniper crown care procedures
The juniper crown of Virginia "Gray Oul" often acquires an attractive appearance even without the intervention of a gardener. However, you can improve its decorative qualities by cutting.
It should be carried out carefully, avoiding excessive shortening of the shoots. Since, due to their slow growth, the juniper bush will take a long time to recover. In the case of Gray Owl, annual sanitary pruning is indicated to remove weak and damaged shoots.
Gardeners inexperienced in growing juniper are advised to use the services of specialists so as not to harm the appearance and health of the shrub.
Preparing juniper bushes for wintering
Due to its winter hardiness, the Virginia juniper "Gray Oul" does not feel the need for shelter for the winter period. Frost protection is needed only for seedlings planted in open ground in the current season.

- Young, but lignified shoots cut in August are suitable as cuttings.
- Cutting cuttings is best in cloudy but dry weather. This should be done with a sharp sterilized garden tool.
- It is recommended to soak the cuttings in solutions that stimulate the development of the root system. For this purpose, "Kornevin" or "Epin" are suitable.
- Cuttings treated in this way are placed in containers with a nutrient substrate, watered and removed to a warm room. The root formation process takes place faster at temperatures from 16 to 20 degrees.
- As soon as the leaves appear, the room temperature should be increased to 26 degrees.
- Watering and spraying of future juniper seedlings is required weekly to maintain the moisture level necessary for them.
- A transplant to a permanent place can be carried out only a year after the roots of a young juniper bush have formed.
Reproduction of juniper layering is even simpler and involves the following actions:
- The soil around the juniper bush should be thoroughly loosened and fertilized.
- You need to choose one of the lower shoots close to the ground. Remove the needles from it and fix it in a small recess dug in the ground.
- Then the shoot is sprinkled with earth and watered abundantly. After that, the soil surface is mulched with sawdust, peat or pine needles.
- In the next season, in the spring, the shoot that has already taken root can be separated from the parent bush and transplanted into a pre-prepared planting hole.

It is much easier to prevent the disease than to treat it later, therefore it is necessary to carry out preventive procedures in a timely manner:
- loosening the soil and weeding weeds prevent the formation of an environment favorable for the development of pathogens;
- removal of weakened shoots marked with traces of infection during the process of sanitary pruning will prevent the development of infection;
- all plant residues must not only be removed from the territory of juniper plantings, but also burned;
- at the first symptoms of a fungal infection, the juniper should be treated with a biological product such as "Fitosporin".
