Good afternoon, my reader. The blue spruce not only attracts with its appearance, but is also unpretentious to care for and easily tolerates even the most severe frosts. Different species differ from each other in height. In home gardens, a spruce is very popular, which does not even reach a meter in height, but has a crown width of 2 m.

Timely procurement of future planting material
The best time to pick the twigs that act as cuttings of blue spruce is on a cloudy morning in early May. Twigs must be taken from young trees that are not even 10 years old. The size of the cutting should be at least 8 cm, but you should not pluck more than 15 cm. It is important to separate the branch with your hands so that a thickening from the bark of the mother tree remains at its base. It will not allow the resin to clog the young seedling, and it will be able to absorb moisture in the amount it needs.
The cuttings are placed in a plastic bag and placed in the ground on the same day. Before planting, they can be left in any rooting stimulator for 2 hours.
Germination of cuttings in the refrigerator and the method of rolling
If the branches have already been plucked, and the planting site or soil has not been prepared, you can germinate the cuttings in the refrigerator. To do this, they are left in water for an hour, at this time sand is poured into a dense bag, into which branches are planted to a depth of 2 cm. The package is kept in the refrigerator for 2 weeks, after which they are transplanted into a greenhouse or greenhouse. The roots will appear in about 60 days.
IMPORTANT! When germinating in the refrigerator, cuttings are not treated with a root stimulator.
The method of self-rolling germination is not only original, but also very convenient. It is ideal for those who do not have a place to grow spruce. A roll-up is a tape that consists of two layers.
- The first layer is a cotton towel or insulation under a laminate (linoleum) about 15 cm wide.
- The second layer is moss, if it is absent, you can use paper towels or napkins.
At the base of the branches, the needles are removed, and they are treated with a stimulant powder. The second layer is laid on the rolled first layer of the roll. Moss or napkins moisturize well and put the lower part of the branches on them. The whole tape is rolled up and tied, placed in a bag and hung on a window where there is no sunlight. As soon as the top layer of the roll is dry, it is moistened.
Cuttings on the windowsill
A 5 cm high drainage is poured into a small pot or cut off the bottom of a plastic bottle. Fill the container with coniferous soil or leafy soil. About 5 cm of sand is poured on top of the soil. The base of the cuttings processed in a growth stimulator is placed in a pot to a depth of 2 to 6 cm at an angle of 30 °. Produce moderate watering. The planted branches must be regularly sprayed with a spray bottle. The optimum content of containers with planted material in partial shade.
Reproduction in a greenhouse
In a greenhouse, one of the important conditions is compliance with the temperature regime. The air temperature at the minimum mark should not be lower than + 13 ° С, soil - + 10 ° С. The best indicators are air temperature + 19-25 ° С, soil - + 20-26 ° С. Drainage is laid at the bottom of each hole before planting - this will help to avoid root rot. The drainage is covered with nutritious soil, the layer of which is at least 10 cm, and on top of the soil with sand - 5 cm. The seedlings are deepened 5 cm into the ground at an angle of 30 °, the distance between the planted branches should be 20 cm.
The humidity level in the greenhouse is just as important as the temperature. It is checked by the film, there should be small droplets of moisture on it. To avoid waterlogging, the greenhouse is ventilated daily.
With any method of propagation, it is necessary to pay close attention to the appearance of the seedlings. Redness of the needles indicates infection with a fungal infection, their shedding indicates an excess of moisture. Transplanting young shoots into open ground is carried out carefully so as not to break the delicate roots.
