The magnificent hydrangea is unlikely to leave anyone indifferent with its bright and lush flowering. Most gardeners, once seeing a placer of large corymbose clusters (up to 15 cm in diameter) of flowers of blue, white, lilac or pink color, cannot resist and are eager to grow this ornamental shrub on their possessions. And, by the way, it is not necessary to buy plants saplings. Hortensia reproduces beautifully by seeds, layering, offspring and dividing the bush. We will consider this method of vegetative propagation of hydrangea, as cutting in spring.
Selection and cutting of material
The method of breeding hydrangea garden cuttings in the spring is considered the most effective and therefore common among owners of cottages and personal plots. Despite the fact that it is recommended to engage in cuttings of the shrub during the appearance of buds on the branches (in summer), such reproduction of hydrangea in the spring is quite possible. They are engaged in cutting cuttings in mid-late May, when young green growths have developed on the branches - spring shoots. They will become the material for growing seedlings.
If we talk about how to prepare the hydrangea for breeding in the spring, then special measures are not necessary. It is just important to properly care for the shrubs, producing timely pruning, watering and fertilizing. Use a sharp knife or scissors to cut off the top of the young shoot. Please note that on the future cutting should be 2-3 pairs of leaves - the so-called nodes. The slice itself is performed under the last node obliquely.
Propagation by cuttings of garden hydrangea - planting
Before planting, each cutting should be cut both lower leaves. The remaining pairs of leaves should be shortened by half across the plate. Cut cuttings can be inserted into a pot of wet sand. But experienced gardeners recommend performing several procedures that improve and speed up rooting:
- The room for 2-12 hours in a solution of phytohormones or biostimulants, for example, in a solution Epin, Zircon or HB-101.
- Treatment of the lower part of cuttings with root-forming biostimulants, for example, by Kornerost, Heteroauxin, Kornevin. Powder just powder the ends of the cuttings.
After that, the prepared cuttings should be placed in a box or a pot with wet sand, deepening the lower part by 2-3 cm. Moreover, the future seedlings should be planted obliquely - approximately 45 degrees. After that, the cuttings are sprayed and covered with the usual package or glass jar. Capacity with planting material is placed in a shady place with an air temperature of 18-25 degrees.
Reproduction of hydrangea cuttings - care and transplanting in open ground
In the future, the cuttings will need a systematic ventilation from the cover, frequent watering and spraying the upper part of the plants. With proper care, rooting roots in young plants will appear in a month and a half. The appearance of the root system will mark further transplanting seedlings into separate pots. At the bottom of the tank should be placed a drainage layer, and then the soil prepared from the leaf earth, sand and peat, taken in the ratio 2: 1: 1. Transplanted young plants again set in partial shade.
With the arrival of cold weather, pots with seedlings can be transferred to the cellar. If there is no cellar, the containers are added to the ground in the garden, which will help to prevent the roots from freezing. Do not interfere and shelter leaves or straw from frost.
In the spring, the hydrangea seedlings grown from cuttings are carefully transplanted, together with the earthy clod, into the open ground. For the development of lush crown young plant should be cut in half or even more.
Ways and timing
So, hydrangea can be propagated in the following ways:
- green cuttings
- dividing the bush
Each of these methods has its own undeniable advantages and disadvantages. Further, we consider in detail each of the options.
Different breeding methods suggest the choice of different time periods:
- the division of the bush is produced in the spring before the buds swell,
- Middle July is suitable for grafting, less often - spring, late autumn,
- seeds are planted in standard early springtime,
- hydrangea can be reproduced in spring and autumn,
- offspring - better in the fall.
Paniculate hydrangea is best propagated in the second half of summer, since in the spring this plant is very difficult to detect healthy cuttings. This species is also not very suitable for autumn breeding.
This option is the longest: it takes about three years from the moment of sowing seeds to the first flowering of hydrangea. It should be noted that the seed method is suitable for hydrangea of natural species, but hybrid varieties do not multiply by this method. The fact is that hybrids at home are best propagated vegetatively - this way they better preserve their decorative effect and specific characteristics.
Hydrangea seeds do not need preplant preparation - they are immediately sown in boxes with wet soil. It is not necessary to deepen the seeds into the soil, they are laid out on the surface of the soil, after which the box is covered with a transparent film. Do not forget to lift the film / glass daily so that the seeds can “breathe”.
The first shoots can be observed twenty days after sowing. After that, the seedlings are grown for two years, and in the third year they are planted in the garden. By the time of planting, the hydrangea seedlings reach a length of 30-40 cm.
The most popular breeding method of hydrangea is universal and suitable for all types of flower. The best time for propagation by cuttings is the middle of summer, when buds appear on the donor plant.
The cutting (green) suitable for our purpose is the middle part of the shoot, grown in the past or the current year, having several leaves and buds. They usually take cuttings from young specimens - they take root better.
Cuttings are recommended to cut from the side shoots located at the bottom of the bush. It is only important that the cutting grows in the sun, and not in the shade - otherwise the planting material will not be too strong. A good future seedling should be in good health and have no damage, the buds on it should be large and developed.
Cutting of shoots is recommended in the early morning in order to preserve maximum moisture in future seedlings. Immediately put in the water, and then proceed to cutting from the shoots of cuttings for subsequent rooting. A green top with a bud is removed from each shoot — this part is not suitable for planting.
Part of the shoot without apex is divided into two or more parts (depending on the length of the shoot, the number of buds on it). It is important that each delenka has at least one bud and a pair of leaves. From the bottom of each delenka leaves are removed, after which the planting material is placed in a solution of root growth stimulator:
Preparing the solution according to the instructions, after which the cuttings are kept in it for about two hours in a dark place. It is important to make sure that only the stem and not the leaves are in the solution.
Attention: it is possible to use both root stimulator and HB101 preparation, however, it is necessary to maintain planting material in it for only half an hour.
After treatment with root stimulator, the time rooting cuttings. Planted them in a pre-prepared soil mixture consisting of a torus (2 parts) and sand (1 part). Soil mixture should be hydrated. To create the most favorable conditions, the cuttings are covered on top with glass or plastic transparent cans - this measure allows you to create a warm, moist microclimate.
Water seedlings should be regularly, and in hot weather - more often. If the banks do not cover planting material, it is also necessary to additionally spray cuttings to ensure a normal level of moisture.
Approximately in 25-30 days the cuttings take root - a signal of this is the formation of new young leaves. After rooting banks removed. If plants take root immediately in open ground, it is recommended to cover them with a temporarily soft material to protect them from returning frost. If rooting occurs indoors, this measure can be neglected.
First-year seedlings are necessarily covered and before wintering. To do this, use the fallen leaves, frame mesh structures, agrofibre, fir and spruce branches.
Features of spring grafting
In this case, the cuttings are obtained during the traditional spring pruning of hydrangea. The escape must be cut from a lignified branch, but it must itself be young, flexible. After cutting the shoots immediately put in the water for five days. Water should be changed daily. After five days, you can begin cutting the shoots for further reproduction.
Try to cut the cuttings from the bottom at an angle of 45 degrees - this will increase the chances of successful rooting of the young plant. It is also recommended to sustain the cuttings in the root stimulator solution.
When spring rooting is better to plant cuttings in the wet sand. The container is filled with sand about half, after which the cuttings are planted in it.
The lower part of the cutting should be recessed about 3 cm. After planting, the seedlings are sprayed with water, covered with a transparent film on top. Do not forget to daily air the planting material and moisten the sand periodically.
To make the seedlings take root faster, make sure that the temperature in the room is suitable - from +15 to +25 degrees, not lower and not higher. When the cuttings take root, they are planted in separate containers. In diameter, such a container should be about 10 cm.
Young seedlings must be kept in a shaded place so that aggressive sunlight will not damage them. Growing up in the ground when cutting steadily warm weather occurs.
Features of winter grafting
Reproduction of hydrangea cuttings can be made in late autumn - a good option, which gives quite predictable results. Further step by step technology of the winter version of the procedure.
- The maternal plant is dug out of the ground in the second half of October. It is important that there is still time before the first frost.
- Hortensia is transplanted into a pot with the earth and placed in a dark, cool, but dry basement. If the potted earth begins to dry, it must be watered.
- In the middle of winter (in January), the plant should be moved to a room with a temperature of +10 degrees. And soon it will be possible to observe the bud break, the formation of young shoots.
- Around the end of February, shoots become sufficient for rooting length, and they already have 3-4 pairs of leaves.
- From the shoots cut cuttings, excluding the top. The cuttings are then kept for 2 hours in a solution of the root stimulator and planted in containers with nutrient soil (or with moist, coarse sand). From above, it is desirable to form a mini-greenhouse of the film.
- A month later, the mini-greenhouse is removed (gradually, in layers), after which the rooted seedlings grow on the windowsill until the beginning of consistently warm weather. In the middle of May, if the weather permits, it is already possible to plant them on a garden bed, choosing a shaded place, protected from direct sunlight.
Features cutting tree hydrangea
This species can reproduce well by cuttings in the fall. To do this, before the onset of frost, cut off the apical shoots with several leaves.
The cuttings are washed with a solution of Fundazol to avoid infection, and then they are planted in containers with permeable, loose soil. Water the first seedlings with a better solution of Phytosporine to prevent rotting of the lower part of the seedlings in the ground.
Top saplings covered with a mini-greenhouse of the film (you can loosely wrap the usual plastic bags) and placed on the windowsill. Rooting occurs at room temperature and subject to daily airing of seedlings. A month later, the plant takes root.
If the weather is cloudy in winter, additional artificial lighting should be provided so that the plants feel and develop well. Cuttings of tree hydrangea are grown to spring, and when warm weather sets in, they are planted on a bed.
This method is rarely used, usually - when transplanting a hydrangea bush. This breeding method is used for all types of hydrangea except paniculate. The optimal timing is early spring.
Before the procedure, it is necessary to water the bush thoroughly, then carefully dig it out, trying not to damage the roots. After digging up the rhizomes, they wash off the old soil, remove the damaged and dried parts.
The bush is divided into several parts - it is important that each part has its own rhizome, otherwise it will not be possible to grow hortensia. Each delenka planted in a separate place in the garden, pruning pre-roots and shoots.
In this case, hydrangea breeds young shoots. A good way, however, requires concentration, care and caution.
- Next to the bush hydrangea removed the top layer of soil in such a way that the roots on this site are bare. It is important not to touch the roots.
- A coppice sprout is separated along with part of the root. It is better to separate several such shoots at once, in order to increase the chances of success of the operation.
- Shoots are planted immediately on the garden, as they are sufficiently adapted to the outdoor microclimate.
- In the garden, shoots grow for 1-2 years, after which they are seated in permanent places.
This method is the second most popular after cutting. To multiply the hydrangea using this method is best in early spring, before the buds have blossomed. But sometimes they carry out the procedure in September.
First, dig up the soil around the mother bush, then level it. Next to the bush in the ground are grooves with a depth of 2 cm, into which the lower shoots are laid. So that the shoots do not rise, they are sprinkled with a little earth and fixed with spears, other devices.
By the end of the current warm season, the cuttings give several young shoots suitable for further rooting. When the shoots have reached a length of 15-20 cm, they are deformed, repeating the procedure every seven to ten days. So do, until the mound reaches 20-25 cm in height. In October, the layers need to dig, shoots separated from each other. By this period, each shoot reaches about half a meter in length.
For the winter shoots dripping, protect covering material. And the next spring is planted in the ground for growing. In a couple of years (sometimes in a year), young hydrangeas will be ready for transplanting to the garden bed.
How to care
Features care for young hydrangeas after the breeding procedure a bit. In general, standard care, however, for the winter, young plants require careful shelter, protection from the cold. This measure should not be neglected, as it is quite easy for a still weak plant to freeze in our climate.
In the spring, be sure to remove covering material as soon as the sun begins to warm. If you leave the shelter, the hydrangea will be over-humidified under it, and root rot and other negative processes are also possible.
Growing seedlings in the penumbra, in the open, sunny is not recommended.
Be sure to water the young plants, as with sufficient moisture of the soil they take root and grow stronger much faster.
If the hydrangea grows at home, then before planting it in the ground it is necessary to temper it for a couple of weeks on the balcony, on the veranda, on the street.
Some advice on breeding hydrangeas from experienced gardeners.
If you do not have your hydrangea and you need to buy seedlings, make a purchase in the fall. During this period, the largest range of high-quality, strong cuttings.
Propagating by cuttings of garden hydrangea, special attention should be paid to the treatment of the lower part of the root stimulator. This type of plant takes root worse than others, so without this measure, the chances of success of the operation are greatly reduced.
If you did not have time to get the root stimulator, and the cutting must be rooted, you can prepare the solution yourself. The recipe is simple: in a glass of water dissolve a teaspoon of natural honey. After this, the shoot is soaked in a standard manner. Honey has disinfecting properties and helps the early formation of callus - a growth from which the roots later develop.
So, we met with five ways of breeding hydrangea. Each of the options considered is quite working and used: choose the one that seems to you the most simple and affordable. But as mentioned above, most gardeners prefer cuttings - most likely, this option will suit you.
Hello dear readers!
In the previous article on hydrangeas, we met with its species and varieties, with the requirements for growing these lovely flowers.
There was no question about ways breeding hydrangeas. Of course, the easiest way would be to buy a sapling in the nursery.
Но, во-первых, это все-таки дорогое удовольствие, во-вторых, там не всегда есть тот сорт который вам понравился и, в-третьих, сам процесс размножения гортензии тоже очень увлекательное занятие.
Ну так как же размножается гортензия? Существуют по крайней мере пять способов ее размножения: семенами, черенкованием, отводками, отпрысками, делением куста.
Давайте немного познакомимся с каждым из них.
Hydrangea seeds do not require preplant preparation, so they can be sown immediately in boxes for seedlings.
In the soil the seeds should not be embedded. Immediately after sowing, cover the box with glass or plastic wrap. In this case, of course, do not forget that the soil should be wet.
Shoots will appear in about 20 days. Then the seedlings are grown for two years and only in the third year they can be planted in a permanent place in our garden. By this time, our seedlings should be 30-40 cm tall.
Keep in mind that the seeds reproduce well only natural hydrangea, and the varieties bred by breeders with this method of reproduction lose their acquired decorative qualities.
Since we will obviously be engaged in breeding varietal hydrangeas, we will take a closer look at the following methods.
The best way - green cuttings
This way breeding hydrangeas is the most common among summer residents.
It is best to engage in green cutting at the moment when the buds appear - this is about the middle of July.
Let's define what the green stalk is. This leafy part of the stem with one or more buds.
I advise you to cut the cuttings only with young plants. If you already have old bushes, then you need to pre-rejuvenate pruning.
Also, note that cuttings are better rooted from lateral shoots (grown on the growth of last year) in the lower part of the crown, but it should be well lit. Such cuttings have quite developed large buds and without signs of any diseases.
Another very important point is the preservation of moisture in the tissues in cuttings, since the success of rooting largely depends on this. To do this, we cut off the shoots in the early morning, at this time, all the plant's tissues are still filled with moisture, and then in the process of further work with cuttings, make sure that they do not dry out.
Cut off the shoots immediately put into the water in the shade and as soon as possible proceed to cutting the cuttings. At the shoot we cut off the green tip with a bud, as it is not suitable for cutting.
The remaining green part of the shoot is divided into several parts with 2-3 pairs of leaves. After that, the lower leaves from the cutting are removed, and the upper ones are shortened by half and carefully put the cuttings in a solution of some root growth stimulator so that the leaves do not get into the solution.
This may be, for example, root, heteroauxin or zircon. The solution is made strictly according to the instructions and we maintain cuttings in it for 2 hours, preferably in a dark place.
If you didn’t have any root-forming agent on hand, then I advise you to prepare such a solution: dissolve 1 teaspoon of honey in one glass of water. Honey contributes to the rapid formation of callus - a thickening at the end of the cutting, from which the roots grow.
Now you can begin to plant the prepared cuttings. We plant them in advance prepared mixture of peat and sand (2: 1), having previously moistened it. For better rooting, you can cover the cuttings with banks and a couple of times a week (in the absence of rain), pour them directly over the banks.
If the weather is very hot and dry, it is advisable to water the cuttings every day. Cuttings that you have not covered, preferably sprayed twice a day.
Usually in 25-30 days (approximately by the second half of August) rooting of cuttings occurs and new leaves appear on them.
Banks can already be removed from them, but it will be better to cover the seedlings with several layers of any covering material so that early autumn frosts do not damage our still very young plants.
For the winter, they also need a good cover. We fill the saplings with fallen leaves, then set a low frame over them and cover it with a covering material.
For better snow retention, you can also add a lap branches.
In the spring of already rooted cuttings are planted in the garden for further rearing. We plant the seedlings for a permanent place when they are old enough.
We propagated by layering
It is best of all to start reproduction of hydrangeas in layers in early spring even before bud break.
First we dig up the soil around the bush, then level it well. We make radial grooves with a depth of 1.5-2 cm and stack them one by one from the bottom of the bush.
To prevent the branches from straightening, we pin them with specially made cattle and lightly sprinkle them with earth.
For a quicker appearance of the roots, you can apply the following technique: on the layering before the first well-developed kidney, we make a waist of 2-3 soft turns from a soft soft wire;
By the end of the summer, several young shoots should form on each of our layers.
When they reach a height of 15-20 cm, they must be folded, then every 7-10 days the hilling is repeated. And we do it until the height of the mound becomes 20-25 cm.
In October, we separate the cuttings and separate the formed shoots from each other. Their height by this time should be about 50 cm.
We plant the seedlings, and in the spring we plant them on the garden bed. And only a year later they will be ready for planting at a permanent place.
Reproduction by offspring
Growth hydrangea also reproduces well. This method of breeding hydrangeas requires a lot of attention and caution.
To this end, we remove the top layer of soil in the fall and very carefully, so as not to damage the roots of the mother bush, separate the shoots from the shoots.
Separated shoots are planted on the bed and leave them there for rearing, depending on the condition of the seedling, for one or two years.
Transplant and divide the bush
This breeding method is used mainly for transplanting hydrangeas.
It can be used for all types of hydrangeas, except paniculate. It is best to transplant hydrangeas in early spring.
Pre-bush plentifully watered, then dig out and carefully wash the roots of the soil.
Now you can divide the bush into several parts and immediately plant delenki on a permanent place, cutting the ends of the shoots and roots.
Experienced gardeners advise
About this method of breeding hydrangeas, which Victoria Barabash shared with us, I recently read in a gardening magazine. Very budget and original!
If you bought a hydrangea sapling in the fall, then it is just for you.
So, we cut off all the leaves on a sapling, prune undripened green shoots and remove it from the container.
Now it needs to be buried in the prepared trench. We make a trench of such size that it is possible to put a seedling in it obliquely, with the condition that the root ball will be lower and the branches higher.
First of all, we fall asleep the roots of the earth and compact it well. Then, with a fan, lay out all the branches of the seedling and also cover them with earth.
So that our sapling does not freeze in winter, we cover it from above with another layer of peat or humus.
As soon as the bright spring sun warms the earth, on the branches of our buried hydrangea buds will grow.
At first, new shoots will be powered by a common root system, and in the future they will form their own roots.
At the end of summer, prikopan thus, we dig out a bush of a hydrangea and we separate the formed new escapes with own root system.
So, having buried one plant, we can get ten new seedlings with well developed own roots.
Now, dear readers, you have learned how hydrangea breeds and you can successfully plant on your plot a few more varieties of this magnificent plant that you like, or even replenish your budget by growing seedlings for sale.
And I also propose to watch a very good video about the reproduction of hydrangea cuttings in order to visually consolidate the information obtained.
Timing of harvesting cuttings
The timing of grafting directly depends on the planting material. For reproduction in the late spring period (from May to June) young growths are suitable - the tips of the shoots are not more than 10-15 cm long. A similar rule applies when spirea reproduces by cuttings. From late June to early July, shoots with woody base are picked for rooting. In the summer they are better suited for planting. In the autumn, the material is used with the bud buds. It takes root better than others in substrates and gives a copious amount of roots. In some sections, the ovaries of flowers can ripen and produce an abundant color at the rooting stage.
The best time for harvesting is the spring period. It is at this time that the active movement of juice along the trunks begins. Hydrangea shoots in spring receive the maximum amount of nutrients. In this regard, the regenerative potential of the cutting and the chances of a rapid increase in the root system increase.
How to propagate hydrangea cuttings: the selection of planting material
When choosing cuttings of hydrangea, flower growers take several criteria as a reference point:
- The condition of the cortex is taken into account. Fully lignified branches hardly produce roots, while the young quickly give root buds.
- The location of the cuttings is taken into account. Bottom shoots take root 3 times better lateral and less prone to disease. Billets selected from the sunny side, take root worse than the shadow shoots.
- A month before the set of planting materials is set, the mother bush is stopped to be fertilized with nitrogenous agents, since the high concentration of this element accelerates decomposition processes in the cuttings.
- Inspect the state of the foliage. Branches with small leaf plates take root faster. In this regard, large leaves are cut in half.
- Planting material is cut only from a healthy flowering shrub no older than 10-12 years.
Hydrangea grow from cuttings is quite simple. To do this, select the planting material corresponding to the following characteristics:
- size not more than 15-20 cm in length,
- thickness not more than 7 mm,
- the presence of short internodes,
- pronounced growth buds,
- at least 4 developed kidneys.
Such criteria are taken into account when selecting garden and room planting materials. In this way it will not be difficult to get several copies of indoor hydrangeas, care at home for which no more difficult. House bushes grow more restrained, unlike garden ones, but you can admire flowering from the end of April.
Processing of cuttings of hydrangea and rooting methods
Hydrangea can be grown from cuttings of any kind: tree, petiole, paniculate and even large leaf. For this you need to properly prepare the planting material. A couple of days before cutting, houseplants are cleaned in a shade, and garden shrubs are covered with covering material. If there is a growing decorative effect on your site, about planting and caring for which you know quite a lot, then it is worth collecting cuttings and with it in order to get new attractive bushes for landscaping.
After the hydrangea stands in partial shade, proceed to cutting planting material. To work with the plant using only professional disinfected instrument. Suitable pruner or garden shears. For grafting choose shoots with several pairs of nodes. Sprigs are separated from the trunk with an oblique cut.
Large leaves are cut to ½ to reduce the flow of nutrients into the seedlings crown.
The collection is placed for a couple of hours in solutions of biostimulants such as "Epin" or "Cyclops". If this is not possible, the slices are powdered with any stimulator of root formation: “Kornevin”, “Heteroduxin”. Thanks to them, the process of growing from cuttings takes half the time. The stems are sprayed with a weak solution of manganese to give them flexibility and disinfection.
Rooting in water
Before rooting the hydrangea cuttings, you must choose a suitable substrate or prepare an aqueous nutrient solution.
Modern growers practice the following methods of rooting hydrangeas:
Rooting in the water hydrangea is quite simple. Moisture is a favorable environment for the growth and development of filamentous processes. Thanks to this method, a beginner florist will be able to monitor and control the process of forming the root system. By itself, water is not a nutrient medium for plants; therefore, growth stimulants and liquid fungicides are added to it.
- Preparation of a nutrient solution from water and cinnamon (1 tbsp. Spoon mixture per 200 ml of liquid).
- As containers, containers with dark or opaque walls are used, since in the dark the root buds peck faster.
- Placement of cuttings in containers, but not more than 2-3 blanks for every 200 ml of water. The lower part of the stem is immersed in the liquid at 1/6 of the total length.
- During the entire period of forcing the rhizomes, the water in the tanks does not change. As the moisture evaporates, add a warm, filtered solution.
- Autumn cuttings rooted in pritenennyh places, spring with a large number of leaves - on the sunny side.
- In order to avoid decay of the planting material, experts recommend regular aeration of the solution throughout the distillation period.
After the plant has produced several roots with a length of 2 to 5 cm, it is transplanted into slightly acidic soil.
Landing in the substrate
The following mixtures can be used as a soil:
- planting cuttings in vermiculite and river sand in proportions of 1: 1,
- perlite, garden soil, peat and river sand in proportions of 1: 1: 1: 1,
- vermiculite, garden soil, peat, river sand in proportions of 1: 1: 1: 1 with the addition of 1 g of citric acid.
At the bottom of the landing boxes lay out woolen ropes in 5 cm steps. The ends of the ropes are lowered into a container with water, and one of the substrate variants is poured into the boxes. Thanks to the wicks, the soil will be optimally hydrated, and the rhizomes will not rot.
Bottom wrap rags for better heating of the root buds and the early growth of the root system.
Blanks are evenly placed over the entire area of the box with an interval of 10-15 cm at an angle of 45 °. The cut should go into the ground by 2-3 cm. The container is placed on the illuminated area. As needed, water is added to the tank, and when swollen buds are found on the shoots, hydrangea is fed.
With proper planting, seedlings root for a month, after which they are seated on individual peat or plastic pots. They seedlings can be up to 3 months before planting in open ground or moving to a larger pot for home cultivation.
Specificity of grafting different types of hydrangea
In order to reproduce hydrangea as effectively as possible, it is necessary to take into account its typological features. For example, grafting hydrangea paniculata is carried out in the spring, and tree-like - in the autumn.
When preparing large-leaved varieties for transplantation, their leaves are always cut in half, and when planted in open ground, the tops of seedlings are cut 10 cm from the ground for better rooting and tillering. In the case of planting material with panicle hydrangea in the fall, lignified shoots are selected for cutting.
Video about 3 ways of growing new seedlings.
Growing from cuttings is a popular way of growing hydrangeas. It does not require much time and effort, and the percentage of rooting shoots is relatively high. The most suitable time for grafting is late spring. During the cosmetic pruning of the bush gardeners not only give it the desired shape, but also gain planting material. Over the summer, grafted shoots take root, adapt and become suitable for autumn planting in open ground, followed by hibernation under cover.
How hydrangea breeds
Hydrangea seedlings purchased in the nursery, for many gardeners are expensive pleasure. In addition, many gardeners prefer to exchange varietal plants among themselves. Therefore, many novice gardeners are interested in the question: "How to propagate hydrangea cuttings?".
Reproduction can be done in various ways:
- The division of the bush.
- Growing seedlings from seeds.
- Growing otvodok.
- Seating offsprings.
This method is more durable compared to the previous one, but it also does not cause any particular difficulties. Preseeding preparation of the seeds of this plant is not required and they can be sown immediately in a container for seedlings.
Seeds are sown on top of the soil, moistened and covered with foil. Twenty days later, you can see the first shoots. Such seedlings must be grown as a pot for about two years and only in the third year with proper care, seedlings can be transferred to the open ground. Their readiness for transplanting in open ground can be calculated from the growth of a plant, the height of which should be at least 40 centimeters.
Propagated by seeds can only be natural hydrangea. If you take for this the seeds of selective hydrangeas, they can lose their ornamental qualities with this method of breeding.
How to propagate hydrangea layering
Another way of breeding hydrangea in the spring is reproduction by layering. Gardeners use this method in early spring before buds appear on the bushes.
Propagate the plant in this way in the following sequence:
- Dig up the soil around the bush.
- Level the soil.
- Делают бороздки по два сантиметра глубиной.
- Укладывают в бороздки по одному побегу из нижней части куста.
- Прикалывают ветки рогатинами и присыпают землей.
Примерно к концу лета на отводах появляется несколько молодых побегов. Когда эти ветки, достигнут в высоту 20 сантиметров, их следует окучить. Окучивание проводят через каждые 10 дней. Hilling is carried out until the height of the hill is 20 centimeters in height.
Dig out in October and separate the resulting shoots from each other. By this time, the height of the shoots usually reaches fifty centimeters in height. Saplings in the autumn are buried, and in the spring they are transplanted to a garden bed. Replace them to a permanent place only after a year.
Tips experienced gardeners on growing hydrangeas
To grow high-quality hydrangea saplings, you should consider some tips:
- Buy seedlings best in the fall.
- Remove all leaves from a seedling, remove all undigested unripe shoots and remove the seedling from the container.
- A sapling under a slope is buried in a pre-prepared trench. In this case, the root ball should be below the branches.
- The roots are well covered with earth and compacted, The branches of the seedling are fanned out and covered with earth.
- For the winter, the seedling is covered with a layer of peat or humus.
- In the spring, as the earth warms, buds will begin to grow on the branches.
- As the air and soil warms up, new shoots will form their own root system.
By this method, it is possible to get about ten new seedlings from one prikopannaya branch.
Beauty named Hortensia
The family of hydrangeas includes quite a few varieties of shrubs, low trees and even lianas. In nature, they can be found in the south and east of Asia. In the garden and on the windowsills the most common species of hydrangea is a large-leaved (garden). This plant is 1-1.5 m tall with fairly large in size, located opposite each other leaves. Hydrangea blooms in the garden from mid-summer to autumn. Inflorescences are very large, spherical.
There are two types of flowers: small fertile (giving fruits), and large sterile (infertile). The first are located in the middle of the inflorescence, and the second at the edges. Their color in most hydrangeas is white.
Only varieties of large-leaved varieties bloom with red, blue, lilac, pink flowers.
Attention! Coloring of large-leaved hydrangea flowers is directly dependent on the pH of the soil. On alkaline soils, the flowers are pink, on acidic, in the same plant, they will be blue. This is due to the influence of the acidity index on the ability of the plant to absorb more or less aluminum from the soil.
Fruits of hydrangeas - the box, having from 2 to 5 chambers, filled with small seeds.
Reproduction of hydrangeas
Hydrangeas successfully propagated in the following ways:
- division of the bush.
Growing in the first way is a rather lengthy process. Sow in a container with soil in the fall. Seedlings appear after 1.5 months, and, unevenly. Seedlings necessarily dive twice. At the end of spring, the plants are regularly carried outside, thus hardening them. In the open ground young hydrangeas are planted in the third year.
A very simple way of reproduction - layering. At the beginning of summer, the side shoots are deflected to the ground, pinned and sprinkled with earth. Rooted twigs are separated from the parent plant in a year.
The division of the bush is also very easy to propagate the plant. Many species produce root shoots, which are easy to dig up and transplant.
All kinds of hydrangea reproduce very well by cuttings. The best time to spring for grafting is the end of May. At this time, the young tops of the shoots are growing enough, which are used as cuttings.
Sprouting cuttings in graft
In this method of germination, the organization of a special bed in a shaded area of a garden, the so-called cuttings, will be required. To do this, dig a narrow trench with a depth of about 20 cm, the bottom of which is filled with drainage material. Over it there is a nutritious soil. Then 1-2 cm of sand. The cuttings prepared according to the general principle are planted in the cuttings, the arcs are set and covered with film. The bed is watered 1-2 times a week. Periodically air out.
Attention! After the signs of rooting, namely, the formation of new leaves on the top of the cutting, the polyethylene must be removed, otherwise the plants may stop.
For the winter, the handle with young hydrangeas should be well covered, for which a strong frame should be built. Lutrasil is put on top of it, then spruce branches or other insulation. You should not cover with polyethylene - it does not let air through, as a result of which plants may die. Successfully overwintered cuttings are planted in spring in flower beds.
Propagation of hydrangeas in the spring with cuttings is a bit troublesome. But in this way it is possible to breed not one dozen plants of various species on the site, which will delight the entire summer season with lush flowering.
Preparation of the source material
In addition to obtaining a new hydrangea bush breeding cuttings, there are other ways known - planting seeds, reproduction of culture by dividing the bush, layering and offspring. But grafting is recognized as the most effective method, so it is used most often.
Experts advise you to do cuttings in the summer - when buds appear on the branches. But in practice they do it in the spring - in the middle or the end of May. On the branches you can see the new green shoots, which are the material for growing seedlings. A stalk is part of a stalk, on which there are 1 or more buds. Only young shoots are used, old ones require preliminary pruning.
It is better to take root cuttings taken from the side shoots - those that are below the crown. She herself should be normally lit in a natural way. For reproduction, the plant must have large developed buds and no disease. Cut shoots need early in the morning, when the culture is saturated with moisture - depends on the speed of rooting. Special training is not required - the main thing is to take good care of the bush. Normal care - to do in time pruning, watering and fertilize.
Starting the reproduction of hydrangea, fill it with purified, if possible, spring water. Put it in the shade and start cutting. The upper part of the shoot is cut with scissors or a knife. On each handle should be more than 2 pairs of leaves - they are nodes. The cut is made obliquely under the last knot. Before planting, 2 lower leaflets are removed from the cuttings. The rest are cut in half. Cutting planting material put in the wet sand.
Recommended placement cuttings for better rooting in a solution of biostimulants or hormones for a period of 2 to 12 hours. Zircon or Epin suit. The lower part is treated with Kornevin, Heteroauxin or Cornerost.
Composition to stimulate growth can be done independently. Take 250 ml of water, add 1 teaspoon of honey. It helps the appearance of callus - thickening at the ends of the cuttings, from where roots appear. Put in a box or a pot of sand for 2 - 3 cm. Landing will need to be carried out at an angle of 45 degrees.
The cuttings should not touch the leaves and sand. Then cover with plastic or can. The container is placed in a shade with a temperature of 18 - 25 degrees. Rooting after planting with normal care occurs in a month. Care includes transplanting into separate containers with garden soil, peat and sand in a 2: 2: 1 ratio, timely watering. Winter care involves dropping pots into the ground so that the roots do not freeze.
Hydrangea still breeds by dividing the bush. This method is suitable for tree and large-leaved varieties in spring. Carry out digging a bush, pre-fill it. The roots are cleaned, the shrub is divided, each part is placed on a permanent place. For reproduction with cuttings, the soil around the bush should be dug up and leveled. In the prepared small beards up to 2 cm deep, shoots taken from the bottom of the hydrangea are placed.
When they grow to 20 cm in height, spend hilling, repeat it after 7 days. Propagation of hydrangea is carried out and seeds. They are bought or collected by themselves. Seeds are small, planting, they are sown superficially. You can wish it in the winter in the container under the glass or greenhouses. The composition of the soil - sand, leaf, turf ground, humus, peat - 0, 5: 1: 1: 1: 0, 5.
How to use cuttings in spring
In the spring overwintered planting material will go into growth, it is advised to carry out its planting on a permanent place or on the growing in the garden-school. In the hole make 1 tablespoon of mineral fertilizer - in the composition should be potassium, phosphorus and nitrogen. They are mixed. One day before planting, the plant is not watered, so that the earthy clod in the pot is separated from the walls. For a luxurious bush, the sapling after planting is pruned by two thirds. If you want a plant with a small trunk, leave everything as is.
Hydrangeas tend to form root shoots. Under normal care, growth shoots retain signs of maternal culture. If you need 2 - 3 seedlings, find in the ground and dig a root close to the surface. It is divided into parts, each has 3 - 4 buds, put them in containers - a mixture of peat and sand in a ratio of 4: 1. Getting plants in this way is harder.
Caring for hydrangea in the spring and in other periods includes abundant watering. In drought, it is carried out once a week in an amount of up to 20 liters under a bush. The soil must be acidic. Care includes mulching with needles, leaves and bark. Loosening to a depth of 5 cm - 2 - 3 times per season. Bring organic supplements. When autumn frosts construct a shelter for plants - powdered with dry peat, covered with foil. To control pests use drugs Fitoverm, Meta, Karbofos. Conduct competent reproduction of hydrangea.
