If you do not want to go the beaten track, do not look for easy ways, and buying a ready-made hydrangea bush in a pot for further transplanting into the soil seems to be too simple a task, then it’s time to do an independent selection. Of course, we are not talking about breeding a new variety (although later, when there is more experience, why not?) For starters, try different ways of breeding hydrangeas in the garden.
Of course, many gardeners reproduction garden hydrangeas seems superfluous. It's easier to buy the plant in a container and plant it without any problems. That's right, but only if you do not care which variety will grow on your site. And if you are looking for a particular plant? And it does not occur to you either in specialized stores or in garden centers or in nurseries? In addition, people erroneously - on the hydrangea may be a label that does not correspond to the grade. It does not depend on the authority of the nursery.
But a completely different situation. The neighbors have a beautiful bush, but nobody knows the name of the variety. But you are offered cuttings. Do you refuse?
Finally, you had the fantasy to make a long hedge of these beautiful plants. At this point, perhaps, it will be a little expensive. Can still try to propagate the hydrangea bushes, because, as practice shows, it is not so difficult?
And finally, the most important thing. Bought a plant - cutting. Hortensia should grow from a small cutting in your garden - then she will have more chances to register for a long time. Especially this rule applies to heat-loving, in particular broadleaf, hydrangeas. By the way, they are grafted better than paniculate.
Next, you will learn how to propagate garden hydrangea in the garden in various ways.
How to propagate properly hydrangea shoots and dividing the bush
One of the easiest ways to reproduce hydrangea is by dividing the bush and young shoots.
Reproduction overgrowth. Trees hydrangeas reproduce well undergrowth. However, this method requires a lot of attention and caution.
To do this, remove the top layer of soil in the fall and, very carefully, in order not to damage the roots of the uterine bush, separate shoots.
The separated shoots are planted on a bed and left for one or two years to grow, depending on the condition of the seedling. For winter, the bed is covered with foliage and non-woven material.
Reproduction by dividing the bush. This breeding method is suitable for tree and broadleaf hydrangeas and is used mainly in early spring for transplantation. Before propagating the hydrangea in this way, the bush is first watered abundantly, then dug out and thoroughly washed the roots from the soil.
Then they divide the bush into several parts, cuts are covered with coal for disinfection and immediately planted delenki to a permanent place. When breeding hydrangea division do not forget to trim the ends of the shoots and slightly shorten the tips of the roots.
The video "Reproduction of hydrangea in the garden" shows the most popular ways:
Reproduction of garden hydrangea layers
The method of reproduction of hydrangea by layering is ideal for tree-like, broadleaf and petiole species. Other forms of these plants can be propagated in this way only if the bushes are small.
To do this, young external flexible branches are bent away from the growing bush and pin them to the ground (in a hole 15 cm deep) with brackets, tying the ends of the branches to the pegs. To propagate the hydrangea correctly, as advised by experienced flower growers, at the very bottom of the hole, on the underside of the shoot, you must first make an oblique incision a few centimeters long. Then a match is inserted into the incision - tissue damage will accelerate the formation of roots in this place.
The bases of the pinned shoots are sprinkled with a light mixture of soil and peat, regularly moisten the ground (to conserve moisture, cover the filled hole with film or mulch).
As shown in the photo, with such a reproduction, hydrangeas make their own roots with time, and then you can separate them from the mother plant and plant them next year:
Method of reproduction of hydrangea cuttings in the spring (with video)
In general, pruning of hydrangeas, which bloom on the shoots of the current year, is carried out before sap flow. However, if you want to shrub the bushes, then prune it at the beginning of sap flow, before bud break, for better rooting (rooting is of the order of 70%). With this method of cuttings (lignified cuttings) planting material turns out to be of better quality. So, for the reproduction of hydrangeas in the spring, in the first half of April, when you saw that the plant buds began to develop, slightly swollen, it means you can prune the bushes for grafting. Tree hydrangea begins to develop after hibernation more quickly than paniculata, and therefore pruning tree hydrangea should be done earlier.
Cut the shoots, leaving 3-4 buds on them. For the reproduction of spring hydrangeas, cut the cuttings from the resulting branches so that each of them has an 2 node. Make an oblique cut under the lower kidney, and a straight line above the top, at a distance of 2-3, from it. After that, the resulting cuttings will be planted in a greenhouse in peaty-sandy soil, deepening the lower kidney by 3 cm, cover with plastic wrap or a plastic bottle and pour in abundantly. Then water the cuttings every day depending on the dryness of the soil.
In panicle hydrangea cut the shoots of last year to one third the length. Cut the cuttings out of the cut branches according to the tree diagram and plant them in the greenhouse in the same way. Rooted cuttings transplant in the summer in the open ground.
Watch a springtime breeding video of hydrangea to better understand how this agricultural practice is performed:
Reproduction of hydrangea with lignified cuttings in summer
Hydrangea cuttings are usually held in the summer, from mid-June to mid-July. The important point is the preservation of moisture in cut stems, because it determines how productive rooting will be.
Experienced gardeners recommend preparing planting material for breeding hydrangea in the summer like this: cut branches in cloudy weather early in the morning and immediately divide into cuttings. If landing is planned later, put them in the water. Top branches with bud cut off. The remaining stem is divided into parts, so that each of them has from 2-x to 3-x pairs of leaves. Shorten the upper leaves by half and remove the lower ones. For two hours, put the shoots in a solution that stimulates rooting - root, zircon or heteroauxin. You can also cook the root forcing yourself by dissolving a teaspoon of honey in water (200 g). Leaves should not touch the stimulant.
And you can generally not use any stimulants - the roots are formed and so. During the reproduction of hydrangea cuttings before planting in the ground, the upper cut is processed with green paint or garden pitch for disinfection. At a temperature of 15-25 degrees, hydrangea cuttings root usually after a month. However, in summer cuttings, the root system often does not have time to develop well, which can lead to their death in winter. Therefore, young plants need to carefully cover before the first winter, protecting them from frost.
Also, during the reproduction of hydrangeas with lignified cuttings, the roots are grown in water. It usually takes 20-30 days. After reaching the roots 3-centimeric length, they are planted in the ground. However, this method is not very successful - often the lower tips of the cuttings rot, and the plant dies.
Method of reproduction of hydrangea cuttings in the fall
Cutting bushes large hydrangea possible in the fall in September-October, before the winter shelter of bushes. To grow the hydrangea in the fall, cut off the shoots and cut the cuttings so that each has 2 leaf nodes, remove the lower leaves, cut the top leaves in half, leaving a sprout from the bottom bud and top leaf of 1. Lower the stalk with the lower cut into the root formation accelerator, then deepen into the garden soil in the pots to the upper leaves.
During the reproduction of hydrangea in the fall, firmly seal the ground around the cutting, and spread the upper section with brilliant green for disinfection. In pots for rooting cuttings can be planted in several pieces, depending on the volume. After planting the cuttings into the ground at a depth of 1, add the “Glyocladin” tablet - it will protect the plant from root rot. Put the pot in a transparent plastic bag, tie it and put it on the window sill. In winter in frosty weather, protect the pots from the cold with newspapers and ensure that no ice forms inside the bags.
When breeding garden hydrangea cuttings several times a week need to arrange ventilation, but for a short time, so that young leaves do not have time to dry. Old fallen leaves must be removed. In the spring in cloudy weather, take the pots to the street (balcony) to harden the plants. Readiness for planting in open ground determine at the end of twisting and hanging leaves.
The video “Reproduction of hydrangea cuttings” shows how this event is carried out correctly:
Folk method of breeding hydrangeas
In the spring they acquire a strong young hydrangea, which is desirable to propagate. A healthy hydrangea with a closed root system (in a pot) is well developed over the season; By the fall of the plant formed good roots and strong shoots. At the end of August or at the beginning of September, the entire shrub of the hydrangea extracted from the pot is dropped (horizontally) with loose, fertile soil. Pre-gently removed from the bush all the weak and underexposed shoots, inflorescences and leaves.
When powdered with earth, the rhizome of the hydrangea itself must be buried below the shoots of the bush. That is, you need to lay the hydrangea bush roots down into the excavated trench, placing it under a slight slope (approximately in 35 degrees).
When the hydrangea shrub is properly placed, cover the rhizome of the plant with soil and compact it for reliable contact with the roots; to water. Add some more soil to the rhizome and compact it again.
When the hydrangea roots are securely closed, it remains to place each branch of hydrangea in a trench (fan) separately, and then cover the entire bush above with earth. In the spring, when the soil warms up, young shoots will go from this hydrangea bush fully buried in the ground. So many separate trunks will sprout - future bushes with independent roots, as there were buds on the mother bush. It remains only to dismember the bush hydrangeas for delenki and seedlings their. As a rule, all young hydrangea bushes formed by this method bloom in the same year.
With this technique, flower buds can be safely protected from frost in the ground, and the bush of a favorite plant can be multiplied exponentially.

Propagation of garden hydrangea seeds and transplanting an adult bush
Hydrangea seeds do not require preplant preparation, so they can be sown immediately in boxes for seedlings. Precisely right away, because their germination persists for 2-4 weeks (for example, in the hydrangea paniculata). The seeds are very small, so they are not buried in the soil. During the reproduction of hydrangea seeds, immediately after sowing, cover the box with glass or plastic wrap. At the same time, of course, do not forget that the soil should be wet. Shoots will appear in about 20 days. Then seedlings grow for two years and only in the third year they can be planted in a permanent place in the garden. By this time, the seedlings should be X-height 30-40.
Other species of hydrangea propagate with seeds, and the varieties bred by this breeding plant lose their acquired ornamental qualities with this breeding method.
Propagation of hydrangea seeds is difficult, so this is mainly done by experts. In this case, their goal is selection.
This photo shows the propagation of garden hydrangea seeds:
There is one gardening rule, which we must adhere to unequivocally - that which blooms in autumn - it will be easier to survive the transplant in spring, and that in spring - in autumn. So the best time to transplant hydrangeas is early spring. This is especially true for thermophilic hydrangeas that require shelter.
Adult bushes are recommended to prepare for transplanting in the fall. To begin with, the branches of the hydrangea are tied with a rope so that they do not interfere and break off. Then dig a ring trench outside the root system of the plant, along the length and width approximately equal to the bayonet of the shovel. The trench is filled with compost and constantly moistened,
The plant will put new roots in the compost.
Before transplantation, hydrangea should be loosened around the outer edge of the trench and the shrub with young, unharmed roots should be removed. After this preparation, the plant will transfer the transplant easily and painlessly.
Do not forget the important rule: it is necessary to locate the root neck at ground level. For the first time, it is necessary to install props that will support the bush and will not allow it to be blown down by strong gusts of wind. After the root system is well accustomed, props can be removed.
Together with the spring plant transplant, you can make rejuvenating pruning of the branches, so that the bush quickly settled down in a new place.
The second axiom is to transplant under inspiration, and then fresh thoughts appear. If you really need, tree and paniculate hydrangeas can be transplanted even in autumn. Only it is necessary to shade from the direct sun, and to spray a bush several times a day. It is better to cut all the inflorescences - for fidelity. The plant most likely will not die, but next year will not be too vigorous. However, the state of hydrangea will be dependent on the size of the bush and the luck of the gardener.
