Propagation of thuja cuttings in summer. How to propagate thuja, methods, harvesting planting material, rooting Breeding thuja cuttings at home in the spring

Tui reproduction is carried out different ways- seed, root division, horizontal layers and cuttings. Each method has its own characteristics and advantages, but still more popular among flower growers is vegetative reproduction.

Since the seeds lose their germination after 10-12 months, it is necessary to use only freshly harvested seed material for sowing. Sowing seeds begins in December. Planting boxes or flower containers must be filled with prepared soil mixture from rotted earth (three parts), fine sand and peat (one part each) and sow the seeds. Immediately after that, all containers are transferred to a cool cellar or placed in a refrigerator with an average temperature of about 5 degrees Celsius and left for 2-3 months. After this time, the boxes are placed in a warm and bright room with a temperature of 18 to 23 degrees Celsius for growing seedlings. Care of young plants consists in moderate watering, protection from direct sunlight and timely diving of seedlings.

Thuja is an unpretentious plant and its seedlings are developing rapidly. It is recommended that growing cultures be gradually accustomed to bright sunshine And open air. Planting seedlings should be carried out in early June. It is very important that at this moment root system was fully formed and ready to be transplanted into open ground. A strong, healthy and strong seedling will become only with good care in about 3-4 years.

This propagation method is recommended for young plants, since their root part is much easier to separate. In order for the root system to acquire the necessary scale, the plant in summer season you need to plant at a depth of about 15 cm or carry out hilling. By the beginning of autumn, the roots will grow to the right sizes and, having dug up a young bush, you can divide them into separate seedlings and plant them for further independent development.

Reproduction by horizontal layering

When using this method, it must be taken into account that this method is not a guarantee of repeating the typical crown shape. This is one of the main disadvantages of this method. Rooted lower branches can give several seedlings at once, but their external characteristics will not be high level. The resulting crooked seedlings will require good care for several years to get in good shape.

One of the lower branches of an adult plant must be bent to the surface of the earth, pinned with a wire and sprinkled with soil. Full roots will appear in about a year.

Cuttings are used to propagate thuja with needle needles, as well as with a spherical crown. This method is especially effective for young specimens of thuja. In early spring(before the buds awaken), it is necessary to cut cuttings from two or three-year-old lateral lignified shoots 30-40 cm long, treat the cut sites with heteroauxin and root them in a special substrate to a depth of about 2-3 cm. Its composition: perlite, pure fine river sand, vermiculite and peat with high acidity. The substrate should be light and loose, with good air permeability.

When cutting in spring time favorable air temperature - 15-18 degrees Celsius, and in summer period- from 20 to 23 degrees. Soil moisture during rooting cuttings should be moderate. Watering is not recommended, it is better to replace them with regular spraying. To improve root formation, you can use special stimulating solutions. After spring cuttings, seedlings will be ready for winter cold and they don't need any additional coverage. But the “summer” cuttings will not yet have time to get stronger before winter, so it’s worth transferring them to storage (for all winter months) in bright room with a temperature of 10 to 15 degrees.

How to propagate and grow thuja (video)

Thuya enjoys special love among summer residents. Living thuja fences decorate the site very much. But for such work, dozens of seedlings are needed. Therefore, the question of how to propagate thuja is very relevant for summer residents and owners of suburban areas. Unpretentious frost-resistant thuja is often used to decorate summer cottages, adjoining territories. The reproduction of this conifer involves three methods: seed, cuttings, grown trees (ready-made seedlings). Let's consider all three.

The option with seeds is very long, labor-intensive, since at least 5 years will pass by the time the bush is planted in the ground. In addition, thuja may lose its varietal characteristics during development, and the only advantage of such a 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, deciduous land), high-quality seeds. It is important that the seed material has previously been stratified - overwintered under a layer of snow.

With the advent of spring, thuja seeds are placed in containers with nutrient soil, covered with earth mixed with sawdust of coniferous crops. Reproduction of thuja by seeds at home entails traditional concerns: protecting seedlings from the scorching rays of the sun, timely watering, getting rid of weeds, top dressing. After 5 or even 6 years, young thuja can be planted on the site.

Cutting propagation 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 ability to get full-fledged small trees in two or three years. Of the minuses, it is worth noting the reduced endurance and a small percentage of survival of the bushes. For this situation, this is normal, if you do everything according to the rules, then positive result will not keep you waiting.

Consider the propagation of thuja at home by cuttings. What season to choose for this - spring or autumn?

Propagation of thuja cuttings in spring

Most often, novice gardeners are concerned about the question - reproduction of thuja in the spring, how best to do it. With spring rooting, all processes are faster, as the movement of juices in the shoots is activated. blank planting material practically no different from the above method. For the selection of cuttings, healthy branches from the top of the thuja, which are no more than 3 years old, are also used.

Reproduction of thuja in the spring is best done in April, with the manual separation of the branch, the “heel” should be preserved. If for some reason you missed April, then you can have time to "catch" the second period of shoot growth - this is June. It should be borne in mind that the June cuttings will "sleep" the summer, autumn, winter, and take root only by spring.

The best way for spring breeding is the substrate method and active moisturizing. Water or the diaper method will not work here due to insufficient moisture during the activation of the root system. The process itself is very similar to autumn cuttings, but sometimes the soil mixture is replaced with clean sand.

Thuja - propagation by cuttings in spring, stages:

1. We put the selected shoots in water with Kornevin for 24 hours.
2. We take boxes or other containers with big amount holes at the bottom, lay a layer of medium-sized rubble.
3. Pour clean sand on top, which can be calcined or doused with boiling water. You can also use the soil mixture mentioned above.
4. Spill the sand with a solution of potassium permanganate, it should be pink, but not too dark.
5. When the sand or substrate has cooled, we immerse the thuja branches there to a depth of 1-1.5 cm, lightly trample it with our hands.
6. Since it is still cool in spring, containers with cuttings should be placed where conditions are similar to greenhouse conditions. At the same time, the air temperature should not be lower than +17ºС, higher than +23ºС.

This place should be shaded, seedlings should be irrigated daily from a spray bottle. If the spring turned out to be hot, then spraying should be done twice a day. At the same time, make sure that moisture does not get on the green leaf plates - the process of decay may begin. After two months, it will become clear which cuttings have taken root, by which time the risk of drying out of the planting material is significantly reduced.

Thuja - propagation by cuttings in autumn

But there is also an opinion that it is the autumn harvesting of twigs for planting that is more appropriate, since in autumn the sap flow slows down, respectively, the number of seedlings dying from lack of moisture decreases. Keep in mind that the rooting process will take longer. Slightly consider the reproduction of thuja in the spring

To collect twigs, it is better to choose a non-sunny day in October, when the leaves have already fallen from the trees (in the Kuban, this may be the beginning of November). It is best to pinch off shoots from the top, it is best to choose those branches that are already 3 or 4 years old.

Select only lignified branches, not exceeding 50 cm in length. The “correct” shoot at the end should 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 go. Remove about 3-4 cm of leaf blades from the end of the shoot and proceed to the next step.

Reproduction of thuja cuttings in a jar of water

Water is the lightest accessible way activation of thuja roots. To do this, take a small container, fill it with water, set the branches so that the water covers the ends by about 2 cm. Do not place more than 3 or 5 cuttings. Make sure that the green parts of the shoots do not come into contact with water - this contributes to the further decay of the planting material. After that, choose a bright, slightly cool place for the container.

Seedling care is a timely replacement of water (when it becomes cloudy). At this time, the cuttings are removed from the jar, the roots are wrapped with a clean, damp cloth. New water must be disinfected with a pair of potassium permanganate crystals.

Rooting cuttings of thuja in the substrate, sphagnum

Propagation of thuja by cuttings in autumn is possible in different ways, for example, using a substrate. This method is more advantageous than the option with water, which does not contain any nutrients, but with the substrate, the rooting process will be much more productive.

To make seedlings healthier, hardier, prepare:

1. Boxes or other forms with holes (for soil aeration). Lay fine gravel (drainage) on the bottom, mix equal parts of leafy humus, sand, peat.
2. Ignite the resulting soil mixture in the oven. If you have potassium permanganate at home, then make a dark solution and additionally spill the soil for reliability.
3. Place the cuttings for 10-12 hours in water with a pre-diluted biostimulating preparation "Kornevin".
4. Fill the containers with the substrate, make recesses for the cuttings. Deepen the seedlings themselves by 1.5-2 cm, sprinkle sand on top (which can also be pre-calcined), lightly tamp.
5. Next, the box should be covered with plastic wrap, put in a bright place, while the air temperature should be +18..22ºС. When condensation appears on the walls of the mini-greenhouse, slightly open the film on one side (for ventilation).

With substrate rooting, it is important not to overdo it with watering and prevent the soil from drying out. Moisturizing is best carried out by spraying with a spray gun, since the weight of water can take the soil, expose the “heel”.

There is another interesting way in which autumn breeding thuja is produced using sphagnum (peat moss). This method implies, as it were, swaddling shoots with a kind of cocoon, this method is called so - rooting thuja cuttings in diapers.

In addition to sphagnum, you will need plastic wrap, a clean cloth, and Kornevin.

1. As described above, we place the thuja shoots in water with a rooting stimulator (for 10-12 hours).
2. Pour the sphagnum with boiled water for about 3 hours so that it swells and is saturated with moisture.
3. We lay out a wide strip of fabric on the table, visually divide its width in half, evenly spread wet sphagnum along the entire length of the upper strip. The lower free part of the width of the diaper will be needed in order to cover the cuttings and moss, and then we carefully roll this strip into a roll.
4. At a short distance from each other, we lay thuja branches, surrounding the “heels” with sphagnum.
5. We cover the cuttings with the lower part of the strip, so that the green tops are free, we turn the roll.
6. The resulting sack is placed inside plastic bag, hang in a well-lit place (but not in direct sunlight).

Such propagation of thuja by cuttings is considered the easiest, thanks to moss, the required moisture level is maintained for a long time. The lack of moisture can be determined by the absence of condensation on the inner walls of the bag - if it is dry, then the diaper should be moistened with a spray bottle.

Growing thuja

Cuttings of spring or autumn harvesting require growing. For this, special beds are formed, which is called shkolka. They will stay there for 2 or 3 years, after which they will be transplanted to a permanent place of residence. Autumn cuttings are planted in shkolku next year, and spring cuttings already in September of this year.

The place for young thuja should be green, the soil should be peat (you can add 1 bucket per 1 m²), the cuttings are planted at a distance of 25-30 cm from each other, watered. At this stage, the seedlings will already gain strength, you just have to take care of them properly - water and destroy weeds in a timely manner.

Tui reproduction is an interesting, productive process, since you can get dozens of "kids" from one tree. After 2-3 years, these will be full-fledged small trees, with the help of which you can plant trees on your site, give it individuality.

Thuja reproduction

Coniferous trees are very popular because of their diversity in shape, variety, color. They majestically adorn not only public places, but also suburban areas. It is possible to propagate thuja by cuttings or seeds. The first method produces a stronger and disease-resistant tree, while the latter is not very popular, since it takes 2 to 6 years to grow.

Thuja propagation by cuttings: timing

It is best to propagate thuja by cuttings in the summer in the last decade of June, during the second growth period. But these seedlings will not take root immediately, but will sleep until next year. Cuttings are also harvested in April, using green annual shoots, but they are harder to root, and they often get sick and die.

Cutting thuja in the summer makes it possible to grow a sufficiently powerful root system for the seedling over the winter after the tree begins to wake up. If the soil was taken from the place of future planting, this will develop adaptability and enhance survival.

Thuja cuttings

The stalk is taken 15-20 cm long from the top of the crown from the growth of 2-3 years. If you take the side branches, then the seedlings can grow twisted.

Please note that the branch is not cut off, but pulled out, since in this case a part of the last year's wood with bark, called the "heel", remains on it. It is in it that the components accumulated by the tree are contained, they serve as a source for rooting a new seedling. The longer the heel, the better rooting occurs.

Branches are suitable, in which the upper part is green, and the lower part is slightly woody. It is better to pluck the branch from top to bottom, so most likely there will be a heel. If the bark on it is flaking, scrape it lightly with a knife to smooth it out. If this is not done, then the cuttings may rot or dry out.

Free the lower part of the cuttings from needles to prevent the formation of rot as a result of contact with sand. Soak them in the Kornevin root-forming stimulator for a day.

Planting cuttings in boxes

Can be dropped off at wooden boxes filled with coarse river sand. To drain and ensure air flow to the roots, make several holes at the bottom of the box, install brick supports at the edges.

Soil preparation

Boil the sand first for disinfection. Pour it into an unenamelled bucket, fill it with water and boil for 5 minutes. Cool and drain. You don't have to wait for it to dry. Add half a glass of 3% potassium permanganate solution, move and pour into boxes.

Landing

• Make holes with a peg at a 45 degree angle.
• Plant the cuttings deepening by 2 cm, at a distance of 5 cm from one another.
• Seal and water.
• Put the boxes in the shade.

In case of frost, cover with polyethylene. Rooting cuttings requires high humidity (up to 70%) at 18-23 °C. If the temperature is higher, remove the film and cover them with damp gauze.

Care

For two months after planting, spray daily, and in hot weather - twice a day. Ventilate the greenhouse regularly. If it is under the film, then water the sand, under the gauze - spray it abundantly.

In autumn, transplant the cuttings to the garden or flowerpots. To prepare the soil mixture, add peat to the leafy soil (in equal proportions). When transplanting, you will see that the rhizome of the cuttings is quite large - 8-10 cm. The seedlings grow for 2-3 years, they need to be watered and weeded.

In addition to the box, there are other methods of rooting cuttings. One of the most favorite methods of professional gardeners is growing in potatoes. Starch and juice nourish the plant and help to quickly develop the root system.

Planting seedlings in the ground

Cuttings can be planted in a greenhouse or greenhouse. The soil should consist of peat, sand and sod land in equal proportions. soil mixture disinfect with potassium permanganate (3%).

You can grow thuja from cuttings at home:

• To do this, they must be planted in flower vases with a diameter of at least 12 cm.
• Make a hole in the soil at a 45 degree angle and place the cutting there.
• Cover with foil, plastic or glass jars.
• Cover from direct sunlight, but leave partial shade and access to light;
• Water as needed and air once a week.
• Roots will appear after 25-30 days, in some varieties - after 15.

The fact that the plant has taken root is indicated by the appearance of new shoots. For the winter, it is better to remove the film, and cover the former greenhouse with fallen leaves or needles. In the spring, the cuttings will wake up and the roots will begin active growth, so as soon as the frosts are over, transplant them by digging them with the ground.

Outcome:

Everyone who wants to decorate his garden will want to plant in it coniferous trees. In order to get the most out of the process and save money, it is better not to buy seedlings, but to propagate the thuja with cuttings on your own, especially since following the recommendations of experts, this is not at all difficult to do.

How to propagate thuja cuttings in summer and autumn - detailed instructions
Do not know how to properly cut and root cuttings coniferous plants? We will tell you how to turn a thuja sprig into a strong, healthy seedling.

Cuttings - the most effective method get NEW TUI PLANTS. Unlike seed propagation, vegetative propagation does not take much time and allows you to save varietal characteristics.

Timing of grafting thuja

Perhaps the most difficult thing in cutting conifers is to correctly determine the timing of this procedure. On this issue, experts have several opinions. Some advocate winter cuttings of conifers in February. Others are sure that it is best to cut thuja in April. Still others argue that the optimal time for harvesting cuttings is summer.

The main criterion that should be followed in this matter is whether the plant has finished growing shoots. If the answer to this question is yes, then you can safely proceed to cuttings.

Summer cuttings of thuja are preferable because they allow the cuttings to gain strength and take root well for the next season.

How to cut cuttings?

For cuttings choose strong, healthy plant. In its upper part, a well-developed skeletal branch is found and, with a sharp movement of the hand, 2-3-year-old lignified growths located at the ends of the shoot are torn off from it. In order for the cuttings to take root faster, they must be torn off with a small piece of bark ("heel").

Thuja grown from a cutting taken from a side shoot can grow irregular shape. The stalk of a diseased plant will naturally turn into a diseased seedling.

If the "heel" turned out to be too long, it is advisable to shorten it a little so that the stalk does not rot. If, tearing off a branch, you slightly peeled off the bark from the wood, the situation can be corrected with a knife - to clean up the cut a little.

The ideal length of the thuja cutting is 10-15 cm.

If the branches are very lignified, and it is not possible to carefully tear them off, use a secateurs.

Can cuttings be stored?

Thuja cuttings are rooted immediately after cutting. You can’t store them, otherwise they will quickly become unusable and will not take good roots.

If you did not have time to prepare everything you need for rooting, the cuttings can be briefly wrapped with a damp cloth and put away in a dark, cool place.

Preparation of thuja cuttings for rooting

First of all, thuja sprigs get rid of excess needles. First of all, it is cut off 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. The bottom of the cutting is also slightly cleaned from the bark.

Preparation of the substrate for rooting

Clean river sand or light, well-drained soil can also be used as a substrate.

The soil mixture for rooting thuja cuttings is prepared from peat, leaf ground and sand, mixed in equal parts.

The soil or sand must be decomposed into shallow containers. For example, containers for seedlings or special cassettes are suitable.

The containers should have holes for drainage and aeration. Be sure to lay expanded clay, gravel or other small pebbles on one.

If you have such an opportunity, use sphagnum as a substrate. This moss perfectly retains moisture and has powerful antiseptic properties. Thus, the cuttings will not be afraid of drying out and fungus.

Rooting cuttings of thuja

When everything is ready for the procedure, remove the cuttings from the growth regulator solution and dip their tips in Kornevin. Immediately after this, insert the cuttings into the substrate at an angle of 45 degrees to a depth of 1.5-2 cm.

Then place the cuttings in a glass or plastic greenhouse, or cover them with cling film or a plastic bag.

If you use sphagnum for rooting cuttings, wrap the cuttings in it, wrap them with gauze and put them in a plastic bag.

Cutting Care

Cuttings are stored in a warm and bright place. However, it is important to consider that they need diffused light. Direct Sun rays thuja cuttings will quickly destroy, and they will wither faster than they take root.

Water the substrate only after it dries out. upper layer. Remember, an excess of moisture is equally detrimental to cuttings, as well as its lack.

Water carefully so that water does not fall on the needles. It is advisable to use a spray gun so that a strong jet of water does not expose the ground around the "heel" of the handle.

The appearance of new shoots on the branches of the thuja indicates that the cuttings have taken root.

If you rooted the cuttings in sphagnum or a common container, two weeks after rooting, you need to plant them for growing in separate containers or shkolka (a special bed on which the plants will grow before planting in a permanent place). Prepare the soil mixture according to the same principle: mix garden soil with high-moor peat or forest litter.

Subsequent plant care consists of regular watering, fertilizing and weeding. In November, young seedlings are covered with spruce branches, leaves or sawdust and left to winter under cover.

Thuja coniferous evergreen, which can decorate your site, because with the help of various kinds these trees can create a great composition. And if you consider that with the help of a haircut you can create beautiful corners, arches, various landscape compositions, thuja can undoubtedly become a favorite in your garden. Many gardeners plant thuja on their plots, as the tree is unpretentious. She does not require special care. With pruning, you can give any shape to the trees on your site. Pruning coniferous plants is one of the interesting and exciting activities for both beginner gardeners and experienced landscape designers. Thuja is one of the most preferred plants in design. We especially note that the more often you cut the thuja, the more interesting, more beautiful and more magnificent its shape will be. In thuja, the needles do not consist of needles (like those of a Christmas tree and pine), but of scales that overlap each other.

Thuja is unpretentious in reproduction, there are several ways to propagate it at home.

Reproduction by seeds

You can propagate the plant by seeds, cones and cuttings. When growing a plant from seeds, the same variety of arborvitae will grow, but a different variety may grow. At the same time, seedlings grow much more slowly, usually it takes about six years. With this cultivation undoubted advantage it will be that when planted by seeds, seedlings will be more hardy than when propagated by other methods.

Reproduction by cuttings

One of the faster and more commonly used methods in thuja propagation is propagation by cuttings. This method is less laborious and it takes much less time for the plant to germinate. When cutting, after 2-3 years you can get a full-fledged plant that can be planted in open ground for the design of your site. For cuttings, you need to choose a tree from which you will take cuttings. It depends on the choice of tree how good your cuttings will be, whether they will take root. Take cuttings from the top, greener part of the plant, which has a beautifully formed crown. The place where you will pinch off the sprouts is also very important. If you take side branches, then there is a chance that the plant may grow crooked and ugly. In order for the cuttings to be good, we recommend taking them not from annual plant, and from a tree of two or more years. Thuja of the first year has not yet managed to accumulate enough nutrients, they may not be enough to grow cuttings.

Prepare cuttings for propagation better in autumn. At this time, sap flow slows down in plants. It is desirable to start harvesting branches during leaf fall. It is necessary to cut off branches from the shoots, while trying to make the heel longer.

After harvesting, determine which rooting method is more reliable for you. Can be rooted

• in water;
• in the substrate;
• in a diaper.

Rooting in water

The easiest way, in our opinion, is to root in water. You need to take a jar and lower several cuttings into it. You do not need to put a large number of them in a jar, 3-4 pieces are left. There should not be much water in the jar, it should slightly cover the heel. Place the jar in a well-lit area. Make sure that the leaf blades do not touch the water, as they may begin to rot. When propagating in this way, there is a high probability that the cuttings will not take root well, since the water contains insufficient nutrients for full growth.

In order to change the water in the jar, you need to pull out the cuttings. Wrap the cuttings in a damp cloth while you change the water. Some gardeners recommend not pulling the cuttings out of the jar, but adding water.

Rooting in the substrate

Many experienced gardeners recommend the method of rooting: in the substrate. To do this, you need to choose a special container with holes. In thuja cuttings, scaly leaves are cut off, then the cut is treated with Kornevin. A little gravel is placed at the bottom of the prepared container, equal parts of river sand, peat and leafy soil are laid out on top. Pour a mixture of peat, sand and earth into a container with holes on top of the gravel. At an angle of 60%, place the thuja cuttings at a shallow depth, pour water and sprinkle with calcined river sand. Next cover everything plastic wrap or a bag and place in a well-lit area. Condensation often forms on the bag, in which case just slightly open the bag. Use a spray bottle to moisten the twigs to prevent rotting.

Reproduction in a diaper

When propagating in this way, we place the cuttings for a day in Kornevin or another growth stimulator. We take a baby diaper, sphagnum moss and a bag. Pour sphagnum moss for 2-3 hours boiled water so that he can soak in. Next, in the middle of the oilcloth, we spread the moss in full length, on top of the moistened moss, lay out the cuttings. We fold the diaper so that the heels are inside, and the tops of the branches are outside. We put the roll in the bag and put it between window frames, can be hung on the window. Moss has bactericidal properties, so the risk of rotting branches is significantly reduced. Watch out for condensation, if there is not enough moisture, you can slightly moisten the diaper.

As soon as you see that leaves are about to appear, or if they have appeared while the cuttings are in a jar of water, place the cuttings in the shade. In the light, a bare stem develops well, and in the shade, the root system of plants develops better.

A little patience, and with proper and not very painstaking care, the thuja you planted will soon grow on your site.

Growing thuja cuttings at home helps gardeners maintain properties mother plants for future trees.
