How to grow a blue spruce: an overview of growing technology from seeds and cuttings


Among all the variety of conifers, blue spruce is considered an elite plant, as it has an amazing color, lush needles and a solid appearance. It is not for nothing that she more often than other representatives of her species flaunts near the houses of government, banks and other institutions that are of considerable importance for the city. Therefore, summer residents increasingly want to grow their own specimen, especially if the territory allows. The prickly beauty is used as a tapeworm, making a kind of accent on the site. And in winter, she becomes the main heroine of the New Year holidays, shining with garlands and lights. But buying a blue-blooded Christmas tree is expensive, so many owners try to propagate it with seeds from cones or cuttings. Let's figure out how to grow a blue spruce from seeds and cuttings.

Preparing planting material

Seed preparation

Growing any spruce, not only blue, begins with harvesting seeds. At the end of summer, look in advance for a suitable blue spruce, the color and shape of which you like best. Check if the tree has formed cones. If they are, wait for the November cold snap and in the first decade of the month pick as many cones as possible from the selected plant. The more seeds you have, the more likely you are to grow a blue specimen.

Only 30-40% of young Christmas trees that sprout from one tree will have exactly the same color as their ancestor. The rest can be blue-green, or even green, like ordinary spruce. This is the problem of seed propagation, in which the traits of the mother plant are inherited much less than during cuttings.

Seeds of blue spruce have a translucent impeller that helps them fly further, but when planting at home, you can remove it by brushing it off with your hands.

You can also collect in February, if you are late in the fall. But then it will have to be planted at the end of June. And this option is only suitable for areas with cool summers. In the heat, the seeds burn from the temperature.

The most difficult thing is to climb the tree, because the cones grow in the upper part of the crown. Tear only tight, completely closed bumps. You can, of course, look under the trees, but it will be difficult to find an unopened specimen.

No more than 30 percent of blue seedlings will grow from seeds sprouted at home, so you can only select the most beautiful ones in a year.

Laying to reveal flakes

Take the collected material to a warm room, where the cones have to ripen, open up and give up their seeds. In nurseries, the opening of the cones takes place in a couple of days, since they are placed in a bunker with a temperature of 40-42 degrees and kept there until the scales open. But in the conditions of an apartment, it is difficult to recreate such a climate, and it is not necessary. It is enough to put the cones in a narrow cardboard box and put them on the radiator.

Those who do not have batteries - put it on a heated floor or take it to the kitchen and hide it at the top on the highest cabinet. The temperature is always higher under the ceiling, so the ripening process will go faster. During drying, you will hear the crackling of the scales. When the bud is fully open, shake out the seeds by tapping the nose on a hard surface.

In an open or half-open cone, there will be almost no seeds, since they will have time to spill out on the ground, so look for cones with tightly closed scales

You can also buy seeds from the nursery instead of collecting them. But choose a trusted company, as the seeds can be stale, stored in warehouses for many years, and the germination rate will be weak. The best option is 1-2 year old seeds.

Stratification, aka hardening

Under natural conditions, cones on spruce open up by January. Seeds fly in the wind to put roots in new places. Until April, they lie under the snow and undergo a hardening process called stratification. At home, you will have to provide the seeds with such hardening so that the plants grow together and have good immunity.

If the winter turned out to be snowless, then divide the collected seeds into 2 parts and sow one of them immediately into the open ground. They will be covered with snow, and the hardening process will take place naturally. Christmas trees are not sown on the snow cover. Sprout the second part at home, and then compare which entrances were more friendly.

How to stratify seeds at home:

  1. Make a 1% solution of potassium permanganate (per 100 ml of water - 1 g. Potassium permanganate).
  2. Submerge the seeds in it and disinfect for 2-3 hours.
  3. Place the seeds on a towel or paper and pat dry.
  4. Pour into a linen bag.
  5. Place the pouch in a glass jar, close and place on the coldest shelf in the refrigerator
  6. In this form, let the future Christmas trees sleep until spring (and with the February gathering - until the 20th of June).

Planting options for blue Christmas tree seeds

After hibernation, the seeds need to be woken up. To do this, they are immersed overnight in a solution of water and microelements (root formation stimulator + antifungal drug foundationol). A moist environment will restore cell structure and accelerate germination.

Landing begins in the morning. To do this, use different methods. You can choose one that is most convenient, but it is better to divide the seeds into equal parts and try each option. So you can clearly see which method is most effective for your particular case and for the plants in your area.

Method # 1 - in open ground

If the spring frosts have passed by April, sow the trees directly into the ground. To do this, knock down the greenhouse and fill it with low-lying peat mixed with coarse sand and earth from a coniferous forest. You can immediately apply complex fertilizers for conifers or feed them later, when the sprouts come out of the ground.

The soil from the forest is an essential component for the good growth of spruces, as it contains the mycelium of fungi. The mycelium in real conditions helps the root system of conifers to receive moisture and nutrition, and takes harmful substances from the soil. The symbiosis of mushrooms and trees is so close that, without mycorrhizal fungi, blue spruces grow sluggishly and often die.

When planting blue spruces in open ground, the seeds are often scattered, since the germination usually does not exceed 50 percent, but then the weakest sprouts are pinched

Work order:

  1. The soil is tamped tightly.
  2. The seeds are laid out on top, at a distance of 3-4 cm from each other.
  3. Peat is mixed with coniferous sawdust in equal proportions and the seeds are sprinkled with this mixture in a layer up to a centimeter.
  4. The land is sprayed.
  5. Cover the greenhouse with foil.
  6. Periodically check the humidity and, if necessary, ventilate the greenhouse.
  7. Seedlings will appear in 3 weeks. They are thinned out, leaving strong plants at a distance of 6 cm.
  8. Sprayed daily in the morning, but without fanaticism, since excess moisture will lead to the development of black leg - a viral infection that can destroy all the material.

In this form, the Christmas trees grow for a year, until next spring. In summer, protect them from the sun and dry soil.

Method # 2 - in plastic containers

You can sprout Christmas trees at home. To do this, you need to prepare wide plastic containers with lids (from store salads, cookies, etc.) or planting pots.

Disposable plastic food containers are inexpensive, but they are convenient for germinating spruce seeds as the container is tightly closed with a lid.

The order of work is as follows:

  • Fill the containers for 2-3 volumes with soil mixture: 3 parts of dry sand + 1 part of peat.
  • Spray the ground thoroughly.
  • Spread the seeds over the moistened earth.
  • Slightly stir the soil with your hand or fork to deepen the seeds.
  • The lid is closed, and if not, cover the pot with foil and put the containers in a warm place where the direct rays of the sun do not fall.
  • As the soil dries up, spraying is carried out.
  • When the sprouts hatch and become visible, the containers are slightly opened so that the plants are normally ventilated.
  • In the summer, the pots are taken out into the fresh air, under the shade of large trees, and in the winter they are returned to a room with a temperature of 10-15 degrees.

Young plants should be planted next spring, in May, when the soil warms up.

The sprouted sprouts of blue spruce are afraid of high humidity, as it leads to various fungal infections and destroys all planting material

Method # 3 - in a roll-up

A very unusual, but convenient way of germinating seeds is considered to be planting in a roll-up. This option is good for those summer residents who do not have large window sills, so there is nowhere to store containers with seedlings.

A roll-up is a long tape consisting of several layers (like a roll).

  • The outer layer is a soft backing made of laminate or other building materials (length - unlimited, width - 10-15 cm).
  • The second layer is toilet paper or napkins.
  • The third is fertile soil.

The essence of the technology is that a landing site is prepared for seeds from the above components:

  1. roll out a support cut into long ribbons on the table;
  2. toilet paper is placed on top of it, filling the entire area of ​​the substrate;
  3. the paper is moistened with water from a spray bottle so that it is saturated with moisture;
  4. spruce seeds are spread on the edge of the paper every 2 cm so that the lionfish protrude slightly beyond the boundaries of the roll, and the seeds lie on wet paper (the seeds should stick to the wet base);
  5. a layer of fertile soil is poured on top;
  6. gently twist the tape into a roll, tighten with an elastic band so as not to unwind;
  7. put the roll vertically on cardboard or a saucer, seeds up;
  8. spray the resulting roll on top;
  9. covered with a film, creating a greenhouse effect, and put in a warm, sunny place.
  10. after pecking the seeds, the film is removed, and the seedlings are looked after, periodically wetting the top of the roll.
  11. in this form, the Christmas trees sit until next spring.

How to plant a spruce from cuttings

Professional gardeners prefer to plant ornamental conifers by cuttings in order to completely preserve varietal characteristics. Blue spruce can also be grafted. This is done in the spring, at the beginning of May, when active sap flow begins in the tree.

For cuttings of blue spruce, young lateral shoots are selected, which are located on horizontal lignified branches. They are carefully plucked against the growth of the shoot.

Rules for harvesting twigs

For grafting, branches from Christmas trees are used, the age of which is from four to ten years. Such trees have the maximum survival rate of cuttings. To prepare planting material, you need to find branches with side shoots and carefully tear off 2-3 cuttings 6-10 cm long.

It is necessary to tear so that at the end of each cutting to keep the heel - a thickening, the remnant of older wood. It prevents the release of resin that can clog the lower cells of the seedling and block moisture from entering the tree. That is why conifers do not cut with a knife, i.e. they do not cut off, but tear.

The thickening at the end of the spruce stalk, called the heel, accelerates the rooting process, since through it moisture freely flows into the seedling.The material is harvested on a cloudy day or early in the morning. The plucked branches are immediately packed in a plastic bag so that they do not dry out, and are planted on the same day.

If, before planting, the cuttings are held in a root formation stimulator for 2 hours, then the Christmas tree will grow roots in 1.5 months. Without stimulants, this process will take 3 months or more.

Cutting at home

All the above methods of planting blue spruce with seeds are also suitable for cuttings. Therefore, here we will focus on other interesting options.

One hundred percent blue color remains only in Christmas trees grown by cuttings, so it is better to look for a suitable tree in the city and pluck the required number of legs from it

There are 2 options - germination in the refrigerator or in a roll-up.

Let's start with the refrigerator. If you managed to pick ornamental spruce by accident, and nothing is ready for planting in the ground, use the trick of an experienced gardener. It is necessary to immerse all the cuttings in water for an hour, and then plant them in wet sand, deepening by 2 cm. The sand is poured into a plastic bag, and the twigs are also there. The bag is tied up - and in the refrigerator. We need a temperature of +3 degrees. And they forget about them for 2 weeks. Further - the usual landing in a greenhouse. With this planting technique, the roots will appear by the end of the second month. When germinating in the refrigerator, do not treat the cuttings with stimulants, as the survival rate will decrease.

When using hand-rolled cuttings, the principle is the same as for seed propagation: substrate + napkins + soil. Just pay attention that the part of the Christmas tree that will lie on toilet paper must be cleared of needles, and the step between the plants is 5 cm.

Winter cuttings

It happens that you saw the desired plant out of season, but you want to collect cuttings. Tear boldly and try to tame them at home in the following way:

  • clean half of each branch from needles;
  • dip the base into the root (powder);
  • put the Christmas trees in the prepared roll: roll out a paper towel, lay a layer of moss over it, moisten it and put the twigs so that the bare lower part is on the moss;
  • twist everything into a roll, tighten with an elastic band;
  • place vertically in a bag;
  • Tie the bag tightly and hang it on the window.

During the winter, half of the cuttings will take root, and in May you will plant them in a greenhouse.

We also recommend that you familiarize yourself with the preparation of conifers for frost: /ozelenenie/zimnyaya-spyachka-xvojnikov.html

Some gardeners use a regular dense film for the outer layer, but it does not have thermal insulation properties, so the seedlings germinate more slowly.

Nuances of planting in the ground

When planting in a greenhouse without prior germination, you need to remember:

  1. The optimum temperature is not less than +13 degrees of air and +10 degrees of soil.
  2. To prevent decay of roots at the bottom of the greenhouse, drainage 5 cm thick is created from gravel and small pebbles.
  3. Blue spruces love light soil.
  4. The distance from the film or glass that covers the greenhouse to the seedlings is at least 20 cm.
  5. Cuttings are planted at an angle of 30 degrees.
  6. They are buried in the soil by 1-2 cm.
  7. The humidity is checked on the ceiling - there should not be large drops hanging, only a fine mesh of dust.
  8. It is necessary to ventilate daily.

It is also important to note that for the first month, the greenhouse is shaded by throwing burlap or spunbond on top to make the sun less aggressive.

The roots on the branches will appear in two months, but they need to be transplanted very carefully, since they often break off when transplanted into the ground

How to grow a blue spruce - growing technology from seeds and cuttings

There is a huge variety of conifers, among which the blue spruce is considered an elite plant, as it has an amazing color, lush needles and a solid appearance. Therefore, blue spruce trees can be seen near the government house, any bank, and near other institutions that are significant to the people.
Because of this, many summer residents want grow a blue spruce and on your site to admire and be proud of her. The prickly beauty is used as a tapeworm, as it is a kind of accent of the site. In the winter season, for the New Year holidays, the blue spruce gathers around itself both children and adults, who decorate it with garlands, balls, tinsel and lights.

So, starting with a blue spruce, then you can grow a whole garden of evergreen beauties with your own hands. The main thing is to find the most successful germination option. And this is a matter of practice.


Types and varieties

Breeders have bred more than 70 varieties of this tree. These include both classic massive trees and low-growing fluffy forms. A number of varieties have been transformed from a tree into a bush, and are up to 2 meters wide and up to 50 cm high.

Artificially bred varieties of blue spruce remain very frost-resistant. Almost all full-size and dwarf tree varieties can easily withstand temperatures down to -35 ºС. This feature makes it possible to grow blue spruce in our climatic conditions.

The most famous and popular varieties:

  • dwarf blue spruce. It is used to frame paths and arbors, does not take up much space and does not hang over your head with heavy branches. The maximum height of most specimens does not exceed 1-2 m. An adult plant growing in a shaded area does not require special care.It is enough to carry out a periodic inspection and treat the surface with protective chemicals. Dwarf spruce propagation is carried out mainly by cuttings

  • the Glauka variety includes 2 varieties: the classic prickly spruce and its miniature companion. A standard tree reaches a maximum height of 25 m and has a growth rate of 10 to 20 meters per year. Dwarf Glauka grows no higher than 2 meters. The tree is planted for decorative purposes in the courtyards of houses, while an ordinary spruce is found within the city limits, does not require careful maintenance and is only subject to periodic pruning as the branches dry. The dwarf variety needs to be paid more attention and monitor the optimal soil moisture regime, avoiding excessive moisture
  • Hoopsie belongs to varieties of medium height (up to 11 m), it is used for planting in parks and forest belts saturated with greenery. The variety is distinguished by the most pronounced blue tint of the needles. Reproduction is done by cuttings. Spruce Hoopsie is the most resistant to microorganisms and adverse weather conditions. Tree maintenance is minimal.


For sowing in a container, prepare a soil mixture from high-moor peat with fertilizers in advance: for a bucket of peat - 20 g of ammophos, 35 g of dolomite or limestone flour, mix well. Arrange in large, approximately 25 cm high plastic containers or pots. Bury them in the greenhouse under the plastic. Before sowing seeds into the soil, it should be prepared in advance, fertilizer should be added.

Before sowing, the soil surface must be tamped, spread out the seeds in 3-5 pieces, covered with a centimeter layer of peat mixed with sawdust of coniferous trees (1: 2) or earth. Seedlings will appear in 10-25 days. They must be thinned out, leaving 1 plant with a strong trunk. The optimum temperature is plus 15 degrees. Protect spruce from night frost and direct sunlight.
