Spruce Canadian: planting and care at home
They are very popular with gardeners: it is beautiful, neat and, of course, useful. Most of the representatives of the evergreen flora are of considerable size, which does not allow to grow all their species, therefore, landscape designers and gardeners give increasing preference to dwarf coniferous specimens, which include Canadian spruce.Its characteristic features, which favorably distinguish a fluffy slow-growing herringbone against the background of other plants, are needles of beautiful color and lowered compact crown, which has decorative outlines. It is these qualities that make Canadian spruce a desirable inhabitant of any plot.
Canadian spruce. Description
Canadian spruce belongs to the category of short trees: the average height of a plant is mainly about one meter, under favorable conditions it can reach three meters. The crown of the plant is dense and cone-shaped, the needles are short, thin and soft, have a gray-green color.The root system is mostly located near the surface and has a weakly pronounced taproot.
Canadian spruce belongs to the category of slow-growing plants. The average growth at a young age is 3-4 centimeters per year, after 15 years - 2-3 centimeters. At the age of 5 years, the height of the Christmas tree reaches about 20 centimeters, it is during this period that the plant's decorative effect is seen, which favorably distinguishes it from a number of even-aged seedlings of the common spruce.By 10 years, Canadian spruce reaches a height of 80 cm, and by 20 years it can reach 1.5 meters, the girth of the crown is approximately 1 meter. Under favorable conditions, the plant is able to please with its appearance not one generation, because it can live 300 or even 500 years. The most popular variety of Canadian spruce is called Conica.
Easy care - the main quality of Canadian spruce
The advantage of coniferous beauty is minimal care: for natural normal growth, natural precipitation and soil fertility are enough, which, of course, can be increased by various supplements. In the summer period, it is recommended to bring 5 kg of rotted organic fertilizer mixed with the soil into the root zone of the tree.In October, it will be useful to mulch the soil with a layer of peat compost about 5 cm thick, which will make it easier for the plant to winter.
In early spring, mulch is required to be embedded in the soil, and to protect against sunburn (spring browning), trees should be wrapped with sackcloth or other material that will protect from rays and preserve natural ventilation. Moreover, the possible russeting of needles is not considered a disease, it is only a reaction of the plant to the spring activity of the sun against the background of frozen soil. That is, the vegetation begins at the tree, and the soil that does not melt is not yet able to provide the roots with the required nutrition, which causes an external change in the needles. With the beginning of the movement of juice and the required nutrition, the color of the plant is quickly restored.
Herringbone should be planted in partial shade, not on a hill and in a place protected from the winds. The tree does not need pruning of the crown, delighting the eye with its natural forms. During the dry period, it is recommended to irrigate through the krone. Also, sometimes loosen the soil around the tree in order to saturate it with oxygen.
Canadian spruce,caring for which is quite simple and does not require the use of supernatural efforts, can change over the entire growing season, it is advisable to do it in cloudy weather. The transplant is most easily tolerated at a young age. Within two weeks after planting, the tree needs protection from direct sunlight, and the optimum moisture level should also be maintained in the soil.
Canadian spruce as decoration
Canadian spruce is very popular in landscape design. It harmoniously looks both in single execution, and in group of plants. When a certain height is reached, the plant effectively looks like an integral part of mixborders and various compositions. Canadian spruce at home is often found in a container on the roof (as a “green roof”), near houses, on terraces and in gardens. The decorative form of the tree fits optimally into large rock gardens, harmoniously combines with other short-growing coniferous representatives, looks great in the background of various flower arrangements.Beautiful green tree bright spot stands out against the background of exactly trimmed lawn.
Canadian Spruce Potted: Care
Coniferous beauty can be considered as a houseplant, but only during the winter period and with “balcony” content. Canadian spruce in a pot looks very elegant; during the Christmas holidays, you can make her a celebration queen by decorating with toys and folding presents for her friends and relatives.
When keeping plants in a heated room, the crown is required to be sprayed. You should also increase the humidity around the tree itself, for this you can place containers with water around the pot. In summer, a pot or a container with a plant is recommended to be placed outside, under trees and shrubs. It is recommended to replant the herringbone in a larger container annually.
Canadian spruce in a pot, care for which is not particularly difficult, can be grown in several ways. The easiest: buy a ready-made tree in the store and transplant it to another land. It is quite expensive, but quickly and without hassle. It is a little harder, but more pleasant (because it is your own work) to grow the lush beauty itself from seeds or from a seedling obtained by grafting.Cuttings that are partly matured lower branches of the mother Christmas tree (always with a “penechnik” at the bottom) should be treated with growth and root formation stimulants before planting. For this fit drugs such as "Epin" and "Kornevin."Transplantation of a young rooted tree into a container should be carried out very carefully, controlling that the root neck of the Christmas tree is located at ground level. Do not let the root system dry out.
The most suitable soil composition for all types of Christmas trees, in parts:
- leaf earth - 2;
- sod land - 2;
- peat - 1;
- sand - 1.
Preliminary, drainage (coarse sand, expanded clay, gravel) should be laid at the bottom of the container in a 10-centimeter layer.
Diseases and pests
Canadian spruce can be subject to some diseases:
- Tracheomycosis (otherwise - soil fungus). Able to hit the root system, especially prefers young plants. With the defeat of such a fungus, the needles of the plant turn red and fall. In this case it is impossible to cure a diseased tree; one can only try to save individual saplings.
- Rust (aka a fungus), causing an orange-colored growth on the branches. The needles begin to turn yellow and crumble.The treatment of such a disease is required by spraying the tree with the preparations “Gliocadin” and “Vectra” once a week for a month.
- Coniferous disease Schutte. This is also a fungus that causes blackening of the needles with the subsequent appearance of white bloom on them and falling off. It is possible to get rid of such an illness by treating the plant with a 3% solution of copper sulfate, and then by spraying with Trichodermin or Alirin B. With a strong defeat of the plants, the latter must be burned.
- Spruce false shield. The female of such a parasitic insect is activated in the spring and lays up to 1500 larvae that look like small brown balls. The needles struck by them fall down; cure the plant can be using the drug "Bi-58".
- Bark beetle. This insect is parasitic under the bark of a tree, laying eggs there. It is almost impossible to escape from such a beetle, because its larvae feed on wood under the bark during the growth period. Therefore, the tree is better to burn in order to avoid further spread of the parasite.
Highlight of any garden
Canadian Spruce has a high popularity due to its decorative and neat appearance, small size, so a wonderful plant can be found in many parts of the world.
Moreover, the breeders derived a large number of varieties characterized by the color of the needles (from light green to gray-blue) and the shape of the crown: conical, spherical, pillow.
