Recently coniferous plants are becoming increasingly popular. They are quite successfully used both for landscaping garden plots and for decorating rooms. One of these plants is conic spruce or Canadian spruce.
Spruce Glauca conica: botanical description of the plant and optimal conditions for growing
Canadian spruce, gray, conic glaucus - all these are names of the same species. Under natural conditions, the height of this tree is about 20-30 meters. For her, a characteristic dense crown of a conical shape, the diameter of which under favorable growth conditions can be more than 1 meter.
The life span of this tree in some cases can exceed 300 years. Usually the branches of young spruce trees are directed strictly upwards, but in the process of aging everything changes and therefore old specimens of these trees differ in branches pointing downward.
The needles of this species have a bluish-green color and a light aroma of blackcurrant leaves. Currently, over two dozen species of this tree are known, most of them were bred artificially.
The conditions for growing this tree in open ground are not much different from the conditions for growing common spruce in our country. The main requirements of glauca conica are as follows:
- A well-lit place, but also quite successfully, this spruce can grow in light partial shade.
- The soil for growing spruce should have a slightly acid reaction. This can be achieved by introducing a sufficiently large amount of peat during planting.
- This species does not tolerate constantly polluted air. Therefore, it is useless to land it on a site near which a busy highway passes.
- For growing picea glauca, places with a close occurrence of groundwater are not suitable.
Pitseya is a rather demanding tree, so if you do not observe even one of the conditions, it will not work to grow a beautiful and healthy tree.
Spruce conic: growing and care
Criteria for choosing a tree for growing a house in a pot
Most Canadian trees are bought on the eve of the New Year holidays. In the store you can find them called conifers mix. As planned by the manufacturers, they are intended only for use as a living Christmas tree; it will not work to maintain them as a home tree without creating special conditions.
What you should pay attention to when buying a Christmas tree:
- Do not buy trees decorated with various sparkles and artificial snow. In most cases, all decorations severely damage the needles, which significantly reduces its chances of further survival.
- It is also worth paying attention to the ratio of the size of the pot to the size of the crown. If the tree is quite large, and the pot is very modest in size, then most likely this Christmas tree was grown on hydroponics and it is unlikely to save it at home.
- When buying, you should carefully consider the state of the root system. Ideally, the entire earthen lump should be tightly braided by the roots.
Spruce Glauka Konika: how to provide care at home
Growing conifers at home is quite difficult, but still possible. Just for this they need to create suitable conditions.
Temperature, lighting and humidity
Save the Christmas tree at home will only be possible if there is enough cold place. In nature, coniferous plants have a dormant period in winter. Similar conditions need to be provided at home. For example, for the winter, a herringbone pot can be taken out onto a cold loggia or placed between window panes.
When keeping spruce at home, the principle applies, the higher the temperature, the less likely the picea to survive. It is best if the temperature throughout the winter will be no more than + 3-5 ° C.
High air humidity is another essential condition for the successful maintenance of spruce. Needles are very sensitive to dry air.. Therefore, the tree needs to be constantly sprayed. Also next to the pot you can place a small container of water.
All conifers are quite sensitive to direct sunlight. Therefore, the pot should be placed on the north, east or west side of the house. An ideal option would be direct diffused light. So that the Christmas tree does not grow one-sided, it is recommended to periodically turn the other side to the light source.
Watering and feeding
Water the plant in moderation increased humidity is only necessary for the crown, for the roots it is destructive. To water it was necessary as rarely as possible the surface of the soil in the pot can be mulched and covered with a piece of paper cut out by the diameter of the pot.
In winter and immediately after transplanting, you can’t feed the spruce. Top dressing should be applied during a period of intensive growth. For this you need to use fertilizers specially designed for coniferous crops. You can not use other types of fertilizing, as they change the level of acidity of the soil.
Additionally, in the spring, the crown of the tree is recommended to be treated with growth stimulants. This will accelerate the process of regrowth of new needles. For these purposes, for example, you can use "Epin"
Transplantation and reproduction
The first time the spruce is transplanted immediately after purchase. This is due to the fact that the soil in the pot is not suitable for long-term cultivation. Spruce of this species is quite demanding on the composition of the soil mixture. Therefore, for transplantation, you need to purchase a special substrate for growing conifers.
It should also be borne in mind that the recovery period of damaged roots can take up to 3 months. Therefore, if the tree was purchased in the winter, then the transplant should be postponed until spring.
Very often, immediately a transplant tree takes a rather deplorable appearance. This is how it responds to stress during a transplant. To help the Christmas tree deal with this, various growth stimulants are used.

How to extend the life of spruce conic at home
To extend the life of the Christmas tree, bought for the New Year holidays and to give her the opportunity to live up to the moment of landing in the open ground need to do as follows:

- Do not allow complete drying of the substrate in the pot.
Spruce Glauka Konika: planting and care in the open ground
Spruce of this kind is not intended for year-round cultivation in indoor conditions, therefore as soon as possible it should be planted in open ground. This is best done in the spring, but if necessary, you can use the autumn landing.
To spruce as quickly as possible settled down in a new place. During transplantation, you should not destroy the earthen lump. You just need to transfer the tree from the pot to a pre-prepared landing pit.
It is advisable to choose a landing site near the walls of houses, fences or near other structures. In the open, sensitive needles are easily damaged by the sun.
For planting, it is best to choose a cloudy rainy day.. This will help to avoid unnecessary stress from transplanting to a new place. Immediately after planting, it is recommended to shade the Christmas tree for a week with covering material. The surface of the soil under the tree is mulched. As mulch, you can use coniferous litter brought from the forest or in its absence peat.
Further care for glauca in open ground is periodic watering. It is especially important to prevent the soil from drying out in the first year of cultivation. At the first wintering, it is recommended to shelter a young spruce. To do this, you can purchase a special cone-shaped shelter, or simply wrap the crown and trunk of the tree with several layers of covering material.
Problems in growing a Christmas tree in a pot
The main problems that can be encountered when growing conics in a pot are as follows:
- Yellowing and shedding of needles. This may be due to the too high temperature of the Christmas tree in the winter. It can also occur as a result of insufficient humidity.
- Burns of needles. Most often occur in the spring. To prevent this, the Christmas tree should be shaded or rearranged on a less sunny window.
- Shedding green needles. It is observed with a sharp increase in temperature or with too much drying of an earthen coma.
