With a variety of shapes and sizes (from narrow and pyramidal giants to small bushes), it will suit any gardener’s idea. Columnar junipers are used as an accent in landscape composition and are also suitable for hedges. By trimming and shaping the shrub that tolerates well, it can be shaped into almost any shape.

Juniper Bush Types and Varieties
What about garden design landscaping with juniper?
Juniper bush is very popular, so experts are trying to develop new, more interesting varieties and forms. Many natural species are also grown quite successfully by gardeners in their garden plots with correct juniper maintenance.
Common Juniper (Juniperus Communis)
These are shrubs or juniper trees, the height of which can vary from 5 to 10 meters. The trunk reaches 20 centimeters in diameter. The tree has a dense cone-shaped crown, and the shrub is ovoid. The fibrous bark is colored brownish-gray, while the shoots are brownish-red. The green, pointed, needle-like needles are triangular. In length, the needles can reach 15 mm, and they stay on the branches for 4 years. Blooming is observed in May. The female flowers are green and the male flowers are yellow. The life span of this plant is about 200 years. Cones are round in shape in diameter up to 10 mm, while immature they have a green color, and mature ones – bluish-black, there is a coating of wax on their surface.
Juniper Virginiana (Juniperus virginiana), or “Pencil Tree”
Such an evergreen juniper plant can reach a height of about 30 meters. In young specimens, the crown has a narrow ovoid shape, then gradually it becomes prostrate due to the branches. The trunk can be up to 1.5 meters in diameter. The peeling bark is colored brownish red or dark brown, and in young shoots it is green. Small, scaly or needle-shaped needles have a dark green color. In diameter, the spherical berries can reach 0.6 centimeters, they have a dark blue color and a bluish bloom.
Juniper Horizontal or Prostrate (Juniperus Horizontalis)
Under natural conditions, these juniper shrubs can be found in Canada and the United States. It prefers to grow in the mountains, on the sandy coasts of rivers and lakes, as well as on the slopes of hills. Its shape can reach a height of about 100 centimeters. It has long branches with densely spaced shoots, painted in a greenish-blue color. The needles can be green or blue, but in winter they have a brownish tint.
Juniper Cossack (Juniperus Sabina)
In height, one of these juniper bushes types can reach 150 centimeters. It grows rather quickly in width, as a result of which dense thickets are formed. Less commonly, you can meet forms with curved trunks in height, which can reach 4 meters. This species has 2 types of greenish-blue needles, namely: in young specimens – acicular, in adults – scaly. Such a shrub has a characteristic feature, if you grind its needles or shoot, then you can feel a pungent smell.
Chinese Juniper (Juniperus Chinensis)
This is a tree with a pyramidal crown, which reaches a height of 8 to 10 meters. However, sometimes there is a bush pressed to the ground or spread out. The peeling bark is grayish red and the shoots are dark green. The foliage is scaly, but at the bottom of the crown or in young specimens there are thorny needles.
Rocky Juniper (Juniperus Scopulorum)
The species is represented by a juniper evergreen shrub or tree, which reaches a height of 18 meters. The homeland of such a plant is North America. The crown begins almost from the base and has a spherical shape. Young shoots are 15 mm thick, they are colored pale green or bluish green. In most cases, scaly needles are found, but there are also needle-shaped leaves.
Scaly Juniper (Juniperus Squamata)
This species is quite variable, and it is represented by an evergreen shrub that can reach a height of 150 centimeters. The color of the bark is dark brown. The tough, sharp needles are colored dark green at the bottom, and at the top they have a whitish tint due to the stripes. Fruit color is black.
Juniper Medium (Juniperus x Media)
This low growing juniper shrubs hybrid is the result of crossing Chinese and Cossack junipers. In this shrub, the shoots have sagging ends. There are two types of needles: inside the crown it is needle-like, and the rest is scale-like. During growth, it has a pale green color, but darkens over time. The height of adult plants is 300 centimeters, while the width is 500 centimeters.
Care of Juniper
Growing and juniper care is easy enough. During the season, watering and juniper bush care should be done only in prolonged heat, while 1-2 buckets of water are taken for 1 plant. Juniper reacts favorably to foliage moisture, which is recommended to be done once a week, especially this procedure is required for Chinese and common junipers( like weeping juniper shrub). Periodically, the surface of the soil of the trunk circle should be loosened and at the same time it is necessary to pull out the weeds. It is recommended to feed the juniper in spring, for this, 30 to 40 grams of nitroammofoska must be distributed over the surface of the trunk circle. As juniper plant care, fertilizer is embedded in the soil, and then watered without fail. In the event that the plant is planted in very poor soil, then it should be fertilized in this way throughout the growing season, but the break in feeding should be at least 4 weeks.
When to Plant Juniper and How to Plant a Juniper Correctly?
- We prepare a 1 by 1 m planting pit.
- For plants that do not like moisture stagnation, we arrange drainage: we pour crushed stone, broken brick on the bottom of the pit.
- Carefully remove the seedling from the container and lower it into the hole (without deepening).
- Pour the soil and water abundantly.
- The planted plants need more accurate regular watering than any other top dressing. In winter, their needles can suffer from heavy snowfall, therefore, in tall and medium-sized shrubs, branches must be tied up. To prevent burning, the creeping forms are covered with spunbond, but usually only young plants need it in the 1st and 2nd years after planting.
The plant propagated by seeds, rooted cuttings and cuttings. Before planting, the seeds must be stratified (kept in the refrigerator for about a month), and before planting, scarified – sawed off the hard shell. For better germination, soil is added to the sowing site from under adult bushes. Seedlings appear in 1-3 years.
How to prune juniper bushes? Green cuttings are taken only from young plants, cut them and soaked in a solution of a root formation stimulator. Cuttings of columnar varieties are planted straight, the rest – obliquely. The appearance of new buds indicates that the stalk has taken root.
