This ornamental coniferous shrub has a flat spherical crown and beautiful thin needles of a bluish-green hue. All these features make it possible to use wood for decorating garden plots. To make it look attractive for as long as possible, it is important to strictly adhere to the rules of agricultural technology.

Distinctive features of a tree

According to the botanical description, black spruce Nana belongs to the Pine family and is a common dwarf variety.The culture is characterized by an ideal spherical crown with bluish-green needles. In height, it reaches 50 centimeters. At the same time, the diameter of the bush does not exceed 1 meter.

Culture is characterized by slow growth and development. For 1 year, it increases by a maximum of 5 centimeters. The plant is characterized by fairly dense needle needles, the length of which does not exceed 1 centimeter. Young shoots are a rich green color that contrasts with old branches.

Cones reach a length of 2-3.5 centimeters and have a spherical shape. At the ripening stage, they are characterized by a purple-brown color. After that, the fruits turn brown.

Black spruce shoots are horizontal and uniform. They have a delicate texture and are quite strongly branched. The root system is near the surface of the earth. Therefore, it is considered quite sensitive to lack of air.

Popular varieties

Besides the Nana variety, gardeners grow many other varieties of black spruce. The most popular ones are:

  1. Baisneri - is a low tree that has a wide round shape. This culture is characterized by beautiful silver-blue needles. This variety is slow growing and is well suited for decorating large spaces.
  2. Kobold is a low growing crop. By the age of 20, its height does not exceed 1 meter. At the same time, in 1 year the plant increases by a maximum of 5 centimeters. The plant is characterized by a dense spherical crown and dark green needles. Culture can be grown in the middle lane. It makes an excellent hedge.
  3. Doumeti - is a low culture that reaches a maximum of 6 meters. It has a wide conical crown and dense branches. The plant has dense needles of a light blue hue. In this case, the cones are located directly on the trunk.

Distribution area

Black spruce is widespread on the borders of the tundra and taiga. It is found throughout almost all of North America. At the same time, spruce grows both in the north of the continent and in the southern regions.

Planting and proper cultivation

It is recommended to buy seedlings of this plant in specialized nurseries. It is important to ensure that the roots are intact and not damaged. Planting work should be carried out in early spring.

To plant a crop, do the following:

  1. Prepare a recess for planting. Its size should be 50-70 centimeters.
  2. Prepare the substrate. Black spruce hardly tolerates too dense soil. Therefore, it is worth using a mixture of turf, leafy soil, sand and peat.
  3. Make drainage. It may include gravel or sand. The thickness of such a layer should be 20 centimeters.
  4. Prepare a pit with substrate. It should be placed in the hole a couple of weeks before planting.
  5. Process the root system. To do this, use a root stimulator.
  6. Plant a spruce. The seedling must be placed in the center of the recess so that the root neck is flush with the ground.
  7. Form a near-stem roller. This will help retain moisture while watering.
  8. Water the seedling. It is recommended to use 2 buckets of water.

Caring for black spruce is easy. In the summer, it is recommended to water it twice a week. It is important to bear in mind that the tree is afraid of stagnant moisture. Dust should be washed off the needles periodically.

In order for the spruce to have a lush crown, it needs to be fed. In the spring, it is recommended to use nitroammophoska. For 1 square meter, it is worth using 40 grams of the substance. In October, the culture needs potassium-phosphorus preparations. In 2-3 years, Fertik fertilizer can be applied.

To saturate the soil with air, it is important to regularly loosen the trunk circle. At the same time, it is necessary to act on the soil carefully, since spruce has a superficial root system. After completion of loosening, it is recommended to cover the soil with a mulch layer. It may be composed of organic or inorganic materials. In the first case, it is worth using hay, bark, needles, in the second - sand, film or stones.

To give spruce the desired shape, regular pruning is required. At the same time, it is recommended to cut off new shoots, removing 30-70% of their length.

Ways to propagate a tree

Black spruce can be propagated by cuttings. The seed method is also acceptable, but it is considered very laborious and not very effective. In addition, this method does not allow preserving the varietal characteristics of the culture.

Pest control

El Nana can suffer from such parasites:

  1. Spruce-fir Hermes. In this case, deformation of the needles is observed and their growth worsens. Preparations "Commander" and "Aktara" help to cope with pests.
  2. Spruce common sawfly. With the defeat of the culture, the young needles on the lateral and apical shoots become red-brown and do not crumble for a long time. To avoid problems, the soil in the trunk circle should be dug up from time to time. In case of severe damage to the tree, it is recommended to use insecticides.

How can spruce be used

Nana is considered a fairly popular variety, which is often used to decorate garden plots. It can be used as a tapeworm or in combination with other dwarf plants. Spruce looks great in a heather garden and in landscape installations in small spaces. Also, the shrub can be grown in containers and used to decorate balconies and terraces.

Black spruce Nana is a fairly popular crop that has pronounced decorative properties. For its cultivation to be successful, it is important to strictly follow the agrotechnical rules.
