Popular coniferous crops in nature are more often propagated by seed or vegetatively. But in nurseries and in the circle of gardeners, thuja reproduction by cuttings in the spring is more common, allowing:
- save time and energy on the germination of seed and bring it to a state of strong viable seedling,
- save all varietal characteristics of the parent plant, which would be necessarily lost in the seed method.
If the summer resident is engaged in independent growing of seedlings for the first time, it is important for him to know how the thuja reproduces.
Preparation of thuja cuttings for breeding in spring
Harvesting cuttings from the branches, their adaptation and planting differ significantly from the well-known technology of working with deciduous species.
The optimal time for planting stock is the end of March and the whole of April. The shrubs that have awakened from winter dormancy begin to grow, so the pieces of shoots cut from them receive a natural stimulus for growth and root formation.
In spring, for reproduction, thuja are cut by cuttings from strong, well-developed shrubs tops not less than 10–12 cm long. The diameter of the future seedling should not be less than 5–8 mm. The one-year-old shoots of the lateral branches taken as cuttings form roots much more quickly and more readily than those cut from the top.
How to proceed? How to propagate thuya cuttings at home? Planting material of many deciduous crops in such a case, it is enough to immerse in a container with water. After some time, the cuttings form roots, with which he will go to the ground for further growth. In conifers, the process of root formation is somewhat difficult, so the handle needs a little help:
- Fresh cuttings at the base cut obliquely.
- Close to the cut, gently hook and remove the bark.
- Above the escape make several thin longitudinal cuts.
- The needles are removed, leaving only at the ends of the shoots.
It is necessary to perform these operations fairly quickly so that the cuttings do not wither.
Thanks to the incisions made, future roots will find it easier to overcome the bark, and removing the needles will help avoid rotting after planting.
In this form, the pieces of the shoots put in a solution of the root stimulator. In a jar of water, cuttings for reproduction of thuja should stay from 12 to 24 hours. During this time, the seizure of rootlets awakens, which increases the likelihood and accelerates rooting.
Rooting and planting thuja cuttings for breeding
While planting material is waiting for its turn, containers and soil are prepared for planting. Tanks should have drainage holes to drain excess moisture. It is convenient to take washed and disinfected sand mixed with peat as a substrate for breeding tui by cuttings. Neutralize the harmful microflora and insect larvae using:
- abundant watering solution of potassium permanganate or phytosporine,
- boiling water, plentifully spilled on a layer of soil,
- roasting in the oven.
The cuttings are planted at a distance of at least three centimeters from each other. When multi-row planting between rows leave 8-10 cm. The same distance should be to the edge of the container or pot.
Cramping is dangerous for seedlings, whose roots are at risk of being tangled and broken off during transplantation into open ground.
Shallow, up to 15 mm holes are made at an inclination of 45 degrees. When all the cuttings of thuja for its reproduction in spring have found their place, the soil around them is compacted a little, and then the plants are watered.
Care for thuja seedlings during vegetative propagation
As long as strong roots do not form on thuja cuttings, they need weather protection:
- direct sunlight
- the rain
- likely spring frosts.
The best shelter for the first two months will be a small greenhouse or greenhouse. At this time, seedlings provide daily watering, which is extremely necessary in dry, sunny, warm weather.
On particularly hot days, rooting cuttings for breeding thuja are useful to spray with warm water using the finest sprinkling. The film on the greenhouse is replaced with a thin fabric or non-woven material.
Over the summer, properly planted and treated plants receive their own roots. Therefore, young thujas can be safely transferred to the place where the shrubs are fully formed in 2-3 years, or into separate pots for cultivation in a container.
The roots of decorative conifers are rather fragile. It is necessary to work with them carefully, trying not to damage. It is more convenient if, during the transplantation, the sapling retains a small earthen ball, which protects the rhizomes and accelerates acclimatization.
A video on reproduction of thuja cuttings at home will help beginners to understand the intricacies of the process and avoid mistakes that will delay the appearance of new evergreen shrubs on the site for a year. After transplanting to the ground, the thujas receive the same care as their adult counterparts. But it is necessary to carefully monitor the cleanliness of the soil under the plants, otherwise weeds can “strangle” small shrubs.
When to conduct tui cutting
Concerning the time for grafting this coniferous plant, the opinions of experts are completely different. If some people believe that cutting should be carried out in February, others are of the opinion that the best time for this is October or July, some say. In general, you should understand.
Preparation of cuttings
It is best to harvest cuttings in the month of October, during the most active leaf fall, choosing an overcast day for this.
For grafting choose sprigs from the top, because then the side shoots can then have a creeping form. In addition, the twigs should choose those that are already woody, so that rooting is more effective. The length of the branches is chosen not more than 50 centimeters.
Harvesting stalk is necessary, cutting off a branch from a tree, and not cutting it with a knife or shears. With this method, a piece of bark should remain with the branch - heel. The more able to grab the heel, the better. In last year's wood there is a supply of nutrients.
The first thing twigs thuya rid of excess needles. First of all, it is cut at the bottom of the branch. If the cutting is too “lush”, you can also partially shorten the needles on the rest of the branch. Bottom cutting also slightly cleaned of bark.
Having prepared the cuttings, it is necessary to deal with their rooting. There are three ways of rooting cuttings: water, substrate, diaper.
The most simple - rooting cuttings in the water.
Pour water into a suitable container no more than 10-15 mm from the bottom, so that water covers only the heel, and the leaves do not touch the water. Capacities are determined in a fairly bright and cool place.
Care for cuttings will consist only in timely replacement of water to prevent rotting of the heels. Getting the sprigs out of the water, you need to wrap them in a damp napkin. Changing the water, we must not forget to rinse the container.
But this method has some drawbacks. In the water there is no set of nutrients, so the plant will be weak, it will be difficult for it to settle down. For more viable seedlings use substrate.
The substrate is prepared from equal parts of peat, leaf soil and sand. The cutting pot is selected with a plurality of vents for ventilation, and a drainage pad made of gravel or expanded clay is placed on the bottom.
Holding the cuttings for a day in the root solution, the cuttings are buried in the prepared substrate by 15 mm at an angle of 60 degrees.
Top soil sprinkled with sand.
After that, for rooting the branches, it is necessary to make a greenhouse, covering them with a suitable material.
Care for cuttings is timely watering the soil. In order not to subside the ground and were not exposed at the same time heels, watering is best done with a spray. It is important to find a compromise when moistening, trying not to flood the plant, but also to prevent the earthen clod from drying out.
Rooting in the diaper. The prepared branches of a thuja soak in a root for 12 hours. In the children's disposable diaper is placed in the center of the sphagnum soaked in water, cuttings are placed on the moss, bending the diaper so that the heels fall between the layers. The diaper is twisted with a roll, which covers only the heels of the branches.
The bundles are put in a film or bag and left to germinate between frames or hang on a window.
This method of rooting thuja cuttings is most effective and does not require special attention and care. Moss and absorbent diaper retain moisture. The cuttings do not lack water, besides sphagnum reduces the possibility of rotting.
Checking the wetness of the cuttings, it is necessary to focus on the presence of condensate inside the package, which will serve as a signal for wetting the diaper.
Thuya cuttings in spring and summer
The most favorable time for spring cutting of thuja is April. It was during this period that there was an increase in the growth of tui. Cuttings harvested from 2-3 year old trees. For better survival of the plant, the cuttings are removed from the plant as well as during autumn rooting. It is necessary to tear off the branch with a sharp movement so that a piece of bark is preserved on it.
It is possible to reproduce the thuja in the same way in the summer period, in June, or in the month of July. But in this case it is necessary to take into account that in the summer the plant begins the second period of growth. Therefore, the cuttings will be ready for planting for the season later, because they will miss the harvesting season.
Thuja reproduction by cuttings:
Reproduction of decorative spring thujas has some peculiarities. Spring - the period of mobility of juice and the beginning of the growth of new shoots. Rooting takes place faster in the spring, but here there are some risks. Rapid growth and development require additional nourishment and moisture. Skipping at least one watering, you can never wait for rooting ever.
The most appropriate way for spring and summer rooting of the thuja is reproduction in the substrate. Cuttings need a lot of moisture and nutrition. Rooting in water or film is not suitable for this.
The instructions for rooting in the substrate does not differ from the rooting procedure in the autumn period.
One has only to add that in early spring the weather is cool enough. Therefore, for rooting cuttings, it is better to determine the greenhouse at a temperature not lower than +17 degrees. But the heat above +23 degrees plants do not like.
During this period, it is necessary to provide the necessary moisture for the cuttings. To do this, it is necessary to spray the plants daily, and in hot weather they do it twice a day. In addition, when the temperature rises, it is also necessary to moisten the soil twice a day. But wet leaves can not be allowed that they did not start to rot. Only a couple of months, when the roots appear, the risk of drying will decrease.
Care in spring and summer breeding is quite troublesome, so many gardeners prefer to do this fall.
Growing thuya in shkolke
After rooting cuttings, they are planted in shkolku.
Shkolka is a specially prepared garden where plants will live for 2-3 years, the field of which they are determined to be in a permanent place.
The cuttings that rooted in the fall are transplanted the following year, and the spring ones are determined to shkolka in the same year, in September.
When preparing the plot for the school, a little peat should be added to the soil. A place for the beds is better to choose in partial shade.
Plants are planted in the garden at a distance of 25 centimeters from each other.
Within a couple of years, the plants will grow up and get strong enough. They can be transplanted to a permanent place.
How to grow thuja from a sprig?
In order to implement spring cutting of thuja, it is necessary to choose the most beautiful branches of a still not stiffened plant, which is not more than 3 years old. In the question of how to propagate thuyu need to focus on the quality of the selected branches. It is better to cut half a meter of green with a small piece of bark at the end. To hold such an event you need to manually in cloudy weather in the morning, tearing the desired cutting by a sharp movement downwards.
At the end of the torn shoot, leave the “woody heel”, which is a piece of bark as the basis for new roots. Need to know one more condition: if the cutting is removed from the tops of the axial shoots of the thuja, then a branch tree will grow, and if the cutting belongs to the side branches of the shrub, the plant will creep in shape.
It is best of all to conduct grafting in the spring on the basis of the fact that it is during this period of the year that all processes in wildlife take place faster, in the shoots of the thuja the movement of juices is activated and the cut cutting will give the first roots faster.
Reproduction thuya cuttings spring is held in late March or early April. If this period of the year is missed, then in June, thuja cutting can also be carried out.
Cutting the thuja cuttings in the spring, when the first wave of growth occurs, the germination of the branches-cuttings captures the entire development cycle of the plant. However, in this case there is a danger that the branches planted for sprouting will fall under the spring frosts. This will help to avoid the establishment of a box with cuttings in the home mini-greenhouse and covering it with film.
Summer cutting of cuttings affects the second wave of growth. In this case, sufficient irrigation of the substrate is necessary, in which the twig gives roots. It is necessary to closely monitor the soil moisture and frequency of watering. Future seedlings can seriously suffer from the summer heat. At this time, the plant is periodically sprayed with a spray gun 2 times a day - in the morning and in the evening.
Thuja breeding occurs with the use of a substrate or plain water. This means that a torn stalk can equally well take root in a glass with plain water, and in the soil prepared for it.
How to grow thuja in water?
In this case, the long tail of the "heel of the heel" is cut off at the newly cut thuja cutting and the lower green growth of the shoots is cleared so that about 5 cm of the clean stem remains. Then the root of the cutting is necessary immerse in water with powder "Kornevin" 2 cm. More than 3 cuttings in one container can not be put so that they do not suffocate.
Be sure to ensure that the branch does not start to rot. To do this, do not lower the green part of the sprout into the water. Such a home germination cutting in water should occur in a bright, cool, but not cold place.
You need to change the water in a timely manner. It can not be allowed to cloud. During the change of water, the cutting is taken from the tank and its root part is wrapped with a damp cloth. In pure water, you must add a couple of manganese crystals for disinfection.
As soon as the cutting starts up the root, it can be planted on the site. First you need to prepare a place for him in the ground.
Growing in substrate
The cut thuja stalk is also easy to grow in the substrate. This method of breeding thuja is considered more reliable, since in this case the sprout is saturated with useful substances. Stages of landing in the substrate:
- We put a sprig in the water for a day with powder "Kornevin".
- We take a box with holes at the bottom and lay drainage on its bottom, for example, crushed stone or expanded clay.
- From above we lay clean sand, which we pretreat with boiling water or garden soil mixed with sand.
- We saturate the sand with a weak solution of manganese.
- As soon as the sand has cooled, the cuttings are immersed there somewhere at 1.5 cm at an angle of 45 degrees and we fall asleep with the substrate. If there are several cuttings, then plant them at a distance of 3-5 cm from each other.
- The box is installed in a place where the air temperature does not fall below 17 degrees and does not exceed 23 degrees. Light must be diffused.
Spray the cuttings daily with room temperature water from a spray bottle. So the water does not blur the "woody heel" cutting. After two months, the tui sprout must finally take root. If the kidney began to appear on the handlethen this is a good sign. Do not immediately plant a sprout in open ground. First you need to harden the plant. The box should sometimes be taken out on the street, so that the plant becomes accustomed to the environmental conditions.
During spring breeding, the Tui plants plant a rooted sprout in a temporary place already in September, where it must spend a couple of three years. This is the so-called school for a young plant. The soil should be filled with peat and hardwood humus, and the place is in light shading. If necessary, scatter 1 bucket of peat on 1 m 2 of land.
Planting a young plant and caring for it
Do not rush to plant sprouts from school to the place prepared for it. Need to think about all the nuances of the future existence of the plant. It should grow in place., well warmed by the sun, which the sun will especially visit in the first half of the day, and in the second part the penumbra will reign from the neighboring trees.
In the well for thuja you need to put a mixture of manure, compost and garden soil. The roots of the plant should not be cracked, and the root neck should be above the ground. After transplantation, it is necessary to water the plant abundantly and put sawdust or pine bark on top. This will be the root system protection. Care must be taken to ensure that the mulch does not cover the lower branches of the thuja and her fragile trunk - they can mate.
Young shoots should:
- регулярно поливать ведром воды раз в неделю,
- опрыскивать из пульверизатора чистой водой, что способствует увлажнению веток туи и смыванию с них пыльного налета,
- на зиму накрыть лапником либо опавшей листвой,
- clean from the shelter in the spring and continue to care for thuja as before.
- cut with pruning shears in spring, removing all dry branches and shortening shoots, shaping the plant so that it does not turn into a shapeless bush of needles.
Thuja reproduction by cuttings is a very interesting and reverent process. A smartly growing tree will be a reward for all the efforts made over the entire period of growing the cutting. This plant will perfectly fit into any landscape design..
Benefits of breeding cuttings
Although the method of propagation of thuja cuttings gives less hardy plants than the seed method, This technique has several significant advantages:
- When breeding a varietal thuja by cutting, there is a guarantee that the resulting young plants will retain all the maternal characteristics, including the appearance, and this is not always available for seed reproduction.
- Cutting allows you to get full-fledged healthy seedlings, suitable for planting on a permanent place in three years.
When the thuja is propagated by seeds taking into account the natural stratification, it will take 5-6 years to get full-fledged ready-made seedlings.
Vegetative method has a significant drawback. Even with all the rules of grafting, the survival rate of seedlings, as a rule, is no more than 75%, and in case of violation of the technology of growing coniferous plants, the number of healthy planting material is sharply reduced.
It is preferable to engage in cuttings conifers in the autumn. In this case, there will be more chances for the rooting of the maximum number of branches, because in the fall the sap flow slows down, which means fewer cuttings will die from lack of moisture. True, time for rooting will take more than when harvesting in the spring, when there is intense plant growth.
Experienced gardeners successfully propagate Tui, like other conifers, on their own. To increase the number of these representatives of the cypress family, there are such methods of plant cultivation as seed and grafting. In the second case, the harvesting processes can be carried out in spring or autumn. For registration, for example, a hedge will require a lot of thuja seedlings. Reproduction by cuttings in the autumn is the most popular way to increase the number of conifers.
Do not engage in the preparation of planting material for breeding evergreen thuja immediately with the onset of autumn. It is better to choose an overcast October day for this event, during the period when active leaf fall begins. First of all, you should take a responsible approach to the selection of processes. The cuttings should be sprigs 3-4 years old. It is better to choose the top shoots of an adult tree, then the future seedlings will form a beautiful, fluffy crown of the correct form.
Absolutely healthy shoots should be selected, making sure that they do not have bark detachments from the wood. It is important to ensure that the cuttings have a woody bark, otherwise the rooting process is unlikely to be effective. The optimum length of the prepared shoot should be 25–40 cm. It is better not to cut the twig, but to break it off so that the wood and woody bark, the so-called heel, remain at its end. A piece of 3 cm from the heel should be freed from scaly foliage.
At the end of the procedure for harvesting cuttings for propagation of plants, you can proceed to the choice of the method of their rooting. It can be rooted in water as well as in the substrate or diaper.
The easiest method of rooting woody twigs - in the water. Pour water into the prepared container. Place only the heel into it, preventing the leaves from touching the surface of the liquid. In each jar should be placed up to three cuttings. It remains to place the tank in a cool place with natural light.
The disadvantage of the method lies in the fact that simple water contains almost no nutrients necessary for the normal development of plants, the cuttings poorly root and then take root poorly.
The way of thuja breeding in a substrate is deprived of this disadvantage, although it is more labor intensive. The procedure in this case will be as follows:
- It is necessary to prepare containers for filling with a substrate, having previously made holes in them for aerating the soil.
- At the bottom it is necessary to build a drainage layer using crushed expanded clay, gravel or other similar material.
- Prepare a mixture of peat, leaf soil and sand in equal proportions. The resulting substrate calcined and shed dark solution of potassium permanganate.
- Cuttings should be placed for 12 hours in a solution of root root - a root growth stimulator.
- Fill containers with ready-made substrate and make holes in them for cuttings.
- Place the twigs in the notches at an angle of 45 degrees to a depth of 1.5 cm.
- Sprinkle the substrate with river sand and consolidate it.
Rooting cuttings can be another simple way. This will require: peat moss, plastic bag, baby diaper and root growth stimulator. The sequence of actions will be as follows:
- Cooked in the fall to get the seedlings of the twigs should be placed for 12 hours in the root solution.
- Spread the diaper so that the absorbent layer is on top.
- Soak peat moss (sphagnum) with cold boiled water and place in the center of the diaper.
- Lay the cuttings on top of the moss, leaving free space between them.
- Bend the diaper so that its layers are between the heels.
- Roll up the roll so that the heels are on one side, and the tops of the shoots peep out from the other.
- Put the received roll in a plastic bag and hang it on the window or place it between the frames.
The advantages of spring breeding: 3 components
Undoubtedly, you can grate thuya at any time of the year. However, when doing this in the fall, you need to be prepared to ensure that the plant has the proper temperature and humidity conditions throughout the winter season. Yes, and the spring should be ready bed-shkanka for long-term cultivation of thuja. But spring reproduction of thuja cuttings is optimal because:
- Thuja is just waking up from the winter, the sap flow is started, but the vegetative mass is not yet gained. Consequently, the plant will not notice the "loss" of several branches.
- The first 1-1.5 months, starting in mid-April, rooting cuttings will develop at the optimum temperature. Humidity should be provided artificially.
- Each owner will have time to transplant the rooted cuttings in shkalku, where they will grow the next 2-3 years. By winter, you will get healthy, strong and hardened mini-plants.
Council Slicing cuttings, make them with a margin. As practice shows experienced gardeners, only 65% of cuttings perfectly take root and in the future will decorate the garden.
The cuttings are different: the rules for cutting
It may seem to some that cutting does not require much effort. However, this is not the case, because only a Tui stalk cut from a certain place and in a certain period (mid-April), which is at least 4-6 years old, can give roots 5-7 cm long in 4-5 first weeks, then take root in shkolke and develop well.
The cutting rules are as follows:
- you need to cut from the branches in the middle of the bush. It should be a branch not younger than 2-3 years old, beginning to harden. The length of the branch is 40-50 cm. It can make 3-4 excellent cuttings, while the diameter of the branch is at least 5-7 mm,
- cutting off branches is worth a sharp knife or shears. A good option is a stalk with a “heel”. This is a separate branch of the required size (10-12 cm), abruptly cut off from the plant. It is this “heel” (part of the central trunk of another branch) that will become the “springboard” for building roots,
- cut off (cut off) all the leaves at the bottom of 4-5 cm. The rest can be left by cutting them in half so that they do not absorb the nutrients that are necessary for rooting cuttings.
A good idea is to process (before planting in the ground or installing it in a container with water) cuttings with a preparation that will help root formation (Epin, Kornevin Ekopin). In this case, you need to dip them in the drug, give the tool to be absorbed under the open air for 30 minutes.
Rooting: substrate, water and wick
Rooting is not necessarily the use of finished soil. It can be successful with a kind of wick or water. Each of the methods has the right to life. You just have to choose the one that you like the most!
Rooting in the substrate: a classic of the genre
Rooting cuttings of thuja in the ground does not require special knowledge. All you need is to prepare the containers. This can be either a pallet with river sand treated with potassium permanganate, or individual containers (volume - 0.5 l). In the first case, the cuttings should be placed in a pallet according to the scheme of 3x5 cm, the rooting depth is 2-3 cm, in the second case it should be planted in a pot of 3-5 pieces. Substrate - peat and sand in a 1: 1 ratio.
An important point of this method of germination is humidity. It can be provided with a plastic wrap cover, as well as daily spraying. In this case, the cuttings must be put in the shade so that they are not burned by open sunlight.
Water and young roots or nothing easier
If you do not want to work with the substrate, you can root the cuttings more easily in a regular can of water. The preparation is the same as in the first case. Treated with Kornevin or a similar preparation, the twigs should be put in a jar of water. It is not necessary to fill it to the brim, it is enough that the cuttings are submerged in water by 3-5 cm.
To prevent water stagnation, you can add potassium permanganate to the jar, and also add fresh water as it evaporates. It is not recommended to change the liquid completely, as it creates its own micro-world, which contributes to the early formation of roots.
For a container with water, it is enough to choose a bright and warm room where direct sunlight will not fall on the plants. Moisture is provided by spraying from a fine spray.
Rooting with a wick: a way that gives 100% guarantee
This method is the most time-consuming, however, providing full survival of the cuttings. There is nothing difficult in it, but it requires careful study of details. Its peculiarity is the possibility of rooting cuttings of many trees, berry and ornamental shrubs in this way. To root thuja cuttings, you must:
- take a 200 gram plastic cup. At the bottom of the hole,
- pass a cord or string through the hole,
- pour a layer of drainage into the glass, on top - a layer of nutrient substrate,
- put a glass on a jar of water, lowering the cord into the water,
- plant cuttings (no more than 3-5 pieces per container),
- top cover with another plastic cup, providing the necessary humidity.
With this method, the first roots will appear in 3-4 weeks, and by the fall they can be planted in shkolku. And no special trouble!
As the practice and experience of professional gardeners has shown, even an amateur can root a thuja at home. Choose the method that you consider the most acceptable - and experiment. Green and lush garden!
How to prepare spring cuttings
In order for the cultivation of thuja from cuttings in the spring to be fruitful, it is necessary to properly prepare the cuttings.
For harvesting spring cuttings need to take the tops of the axial shoots of thuja. These branches retain the nature of branching, which is inherent in this species. If you take the stalk from the side branch, you get the creeping form of the plant.
The best period to separate cuttings from the mother plant is the spring month of April. At this time, the first phase of plant growth occurs. The plant from which the escape is taken must be 2-3 years old.
In order for a thuja to have a better chance of settling down, whereas this plant can not be grown from a cutting plant with a 100% probability with this method of propagation, it is necessary to properly separate the cutting. To do this, it is necessary to tear it off manually, without using a secateur. Tear off need a sharp movement. The detachable part should be 20 cm long. When a branch is pulled out at its end, a piece of last year's wood remains, which contains nutrients.
Primary preparation of harvested thuja cuttings - cleaning from the bottom of the cutting of small twigs and needles. This is done so that they do not come into contact with sand or wet soil, because in this case they will begin to rot.
Features rooting cuttings in the spring
After harvesting, it is necessary to root the thuja cuttings in the spring. Before this you need to disinfect young shoots. To this end, they are immersed in a weak solution of manganese for a few minutes, after which for one day they are placed in the drug "Kornevin" or another growth stimulator.
Existing rooting methods, which one is suitable for spring
The next thing in the process of how to root the thug from the branch is to place the cutting on Wednesday, where it can take root. There are several ways of rooting a thuja:
- in the substrate,
- in water,
- in a diaper with moss.
How to prepare the substrate for cuttings
In the question of how to plant a thuja branch, not the last role is played by the substrate in which the cutting will be placed. As a substrate, you need to use pure river sand or a mixture of sand and garden soil, which must be disinfected.
For disinfection of river sand, it is placed in a galvanized bucket or tank and boiled it, placing it in a large container with water. After that, the sand is poured over with a 3% solution of potassium permanganate. After completing these procedures, sand can be used in the substrate for planting thuja cuttings.
Some carry out sand disinfection, having already placed it in a tank for disembarkation. Sand is poured over with boiling water, and after that with a solution of potassium permanganate.
How to plant a spring stalk
After the preparation of the desired substrate, another task remains to be done - how to root the thuja cuttings in the spring. The procedure is as follows:
- prepare seed tanks with a large number of drainage holes,
- lay a drainage layer at the bottom of the tank - crushed expanded clay or gravel,
- a substrate is laid on the drainage layer - river sand or a mixture of river sand with garden soil,
- prepared cuttings deepen into the substrate to a depth of 1-1.5 cm and compact the soil around them.
Proper care of cuttings - the key to success
The next thing you need to know when investigating the question of how to grow a thuja from a cutting is the rules for leaving after planting. Since the planting takes place in early spring, the outdoor temperature is too low for young branches. Therefore, planted cuttings are placed in a greenhouse, in a shaded place or in a greenhouse of spunbond.
The temperature for growing tui from cuttings should be between 17 and 23 degrees. Spray seedlings should be sprayed daily, and if the weather is hot, then the substrate needs to be moistened twice a day.
What to do when cuttings take root
After the cuttings planted in spring take root, they must be transplanted to grow into a special bed - shkolka. In shlyokuy tui seedlings spend 2-3 years, until they are ready to transplant to a permanent place. Sprigs planted in the spring in spring are placed in a school in the same year, in September.
How to transplant thuya shanks in shkolku:
- choose a site to form a little school - half-shadow is needed,
- dig the soil in the plot, add peat to it at the rate of about one bucket per square meter,
- rooted cuttings need to be watered so that they can be easily removed from the substrate without damaging their roots,
- plant cuttings at a distance of 25 cm from each other in shkolku,
- moisten the soil.
Reproduction of thuya seeds
The seed variant is very long, laborious, since by the time the bush is planted in the ground it will take at least 5 years. In addition, the thuja can lose its varietal characteristics during development, and the only advantage of this situation will be the adaptation of the plant to the local climate. However, if you are interested in the process itself, then you will need a soil mixture (sand, coniferous, hardwood), high-quality seeds. It is important that the seed material is pre-stratified - overwinter under a layer of snow.
With the arrival of spring, thuja seeds are placed in a container with nutrient soil, covered with soil mixed with sawdust of coniferous crops from above. Reproduction of thuja seeds at home entails traditional concerns: protecting the seedlings from the scorching rays of the sun, timely watering, getting rid of weeds, feeding. After 5 or even 6 years, young tui can be landed on the site.
Reproduction thuya cuttings
Cherenkovom reproduction is the most convenient, effective way. A big plus of this method is the preservation of the varietal qualities of the tree, as well as the opportunity to get full-fledged small trees in two or three years. Of the minuses worth noting reduced stamina and a small percentage of the survival of bushes. For this situation, this is a normal phenomenon, if you do everything by the rules, then a positive result will not keep you waiting.
Consider reproduction of thuja at home by cuttings. What time of year to choose for this - spring or autumn?
Туя — размножение черенками осенью
Но существует также мнение, что именно осенняя заготовка веточек для посадки более целесообразна, так как осенью сокодвижение замедляется, соответственно, сокращается численность саженцев, погибающих от недостатка влаги. При этом нужно учитывать, что процесс укоренения займёт больше времени. Chummy consider thuja breeding in the spring
To collect the branches, it is better to choose not a sunny October day, when the foliage has fallen from the trees (in the Kuban this may be the beginning of November). It is best to pinch the shoots from the top, to choose the best branches that have already turned 3 or 4 years old.
Select exclusively lignified branches that are no longer than 50 cm in length. The “correct” shoot at the end must have a woody “heel” - part of the bark, thanks to which new roots will develop. The longer this “heel” is, the better the rooting process will be. Remove about 3-4 cm of leaf plates from the end of the shoot and proceed to the next step.
Rooting cuttings of thuja in the substrate, sphagnum
Reproduction of thuja cuttings in autumn is possible in different ways, for example, using a substrate. This method is more advantageous than the version with water, which does not contain any nutrients, but with the substrate the rooting process will be much more productive.
To make the seedlings healthier, stronger, prepare:
- Boxes or other forms with holes (for aeration of the soil). Lay on the bottom of fine gravel (drainage), mix equal shares of hardwood humus, sand, peat.
- Prove the resulting soil mixture in the oven. If you have potassium permanganate at home, make a dark solution and additionally spill the soil for reliability.
- Place the cuttings for 10-12 hours in water with pre-diluted biostimulant drug "Kornevin".
- Fill the container with the substrate, make the grooves for the cuttings. Deepen the seedlings themselves by 1.5-2 cm, sprinkle with sand on top (which can also be pre-ignited), tamp lightly.
- Next, the box should be covered with a plastic film, put on a bright place, and the air temperature should be + 18..22 ºС. When condensation appears on the walls of the mini-greenhouse, slightly open the film on one side (for ventilation).
When substrate rooting is important not to overdo it with watering and prevent the soil from drying out. Moisturizing is best done by spraying with an atomizer, as the weight of the water can soil the soil and strip the heel.
There is another interesting way in which autumn thuja breeding is performed using peat moss (peat moss). This method involves swaddling shoots as a kind of cocoon, this method is called rooting of thuja in diapers.
In addition to sphagnum, you will need a plastic film, a clean cloth, as well as the drug "Kornevin."
- As described above, we place shoots of thuja in water with a root formation stimulator (for 10-12 hours).
- Sphagnum is filled with boiled water for about 3 hours so that it swells up and gets saturated with moisture.
- We lay out a wide strip of fabric on the table, visually divide its width in half, spread the moist sphagnum evenly over the entire length of the upper band. The lower free part of the width of the diaper is needed in order to cover the cuttings and moss, and then gently fold this strip with a roll.
- At a short distance from each other we lay the branches of the thuja, surrounding the “heels” with sphagnum.
- We cover the cuttings with the lower part of the strip, so that the green tops are free, we roll up the roll.
- The resulting sack is placed inside a plastic bag, suspended in a well-lit place (but not on the direct rays of the sun).
Such reproduction of thuja cuttings is considered the easiest, thanks to moss, the required level of moisture is maintained for a long time. Lack of moisture can be determined by the absence of condensation on the inner walls of the package - if it is dry, you should moisten the diaper with a spray.
