We are used to our favorite hydrangeas being shrubs. But there is one unusual one: a liana that came to us with The Far East... it petiolate hydrangea (Hydrangea petiolaris). In nature, it is found in the mountain coniferous and mixed forests of southern Sakhalin and the southern Kuriles, as well as in Japan.
Petiolate hydrangea forms a mass of aerial roots and suckers with which it attaches to the bark of trees. With their help, the liana sometimes climbs to a height of 25 m.
The petioled hydrangea has bare brown shoots, the old bark is peeling and flaking. Leaves 5-10 cm long, smooth above, dark green, shiny, paler below, with warts in the corners of the veins.
In summer, petiolate hydrangea stands out with large white corymbose inflorescences 15-25 cm in diameter, which also contains larger, sterile flowers. Fertile flowers, in the place of which seeds are subsequently formed, are hardly noticeable.
Although the petiolate hydrangea appeared in gardens as early as the 19th century, it is still not common. It's a pity. At first, in the first years, it grows slowly, but then, having rooted well, it grows quickly, forming a dense green wall, braiding arches, gazebos. In nature, it can be found in moderately humid forests with a monsoon climate. Prefers light, humus-rich, loose and moist soils with good drainage. It blooms with some shading, but especially abundantly - with full sunlight... It spreads on the ground without support, it can grow as a shrub 1.5-2 m high. But it is better to plant it near a tree with rough rough bark to provide support.
The petiolate hydrangea is propagated by seeds, which are sown in bowls or boxes in the spring in cold greenhouses . The seeds are not planted as they are too small. The boxes are covered with glass and a sprayer is used when watering. The cover is removed after emergence. Seedlings of petiolate hydrangea dive into separate cups or in a greenhouse; petiolate hydrangea seedlings are planted in open ground next spring.
but seed reproduction it is still a laborious task, it is much easier to propagate petiolate hydrangea vegetatively, with the help of offspring, easily rooted shoots. One of the vines must be placed on the ground, for example, along a fence or structure, in several places attached to the ground with pins, sprinkled on top, and watered. For better rooting, you can use a root stimulator, although without it, the vine will quickly give roots in places of contact with the ground, and then shoots. For better growth young offspring can be left in place for up to 2 years, and only then can they be disconnected from the mother plant and transplanted to another place.
Stalked hydrangea is relatively winter-hardy. Heavy frosting occurs only after unusually severe winters.
Petiolate hydrangea can be safely grown up to the forest-steppe zone. To the south, the liana has to be shaded, watered often and abundantly, since it is hygrophilous.
Stalked hydrangea is an unusual type of garden hydrangea, which has nothing to do with the tree (or panicle) hydrangea. She has no barrel and does not need constant supervision. The owner of this plant should only water it on time and provide a clean space without weeds.
Climbing hydrangea is grown by residents of many countries. This plant is very popular with European gardeners, thanks to it you can do hedgecreating luxurious flower beds in the garden. Hydrangea is also used to decorate a terrace or home hall. Today there are many varieties of it.
The most common among them:
- hydrangea Sargent is very different large inflorescences, the diameter of which may be about 30 cm, its flowers inside are purple, outwardly it looks pale pink;
- serrated hydrangea has large flattened-spherical inflorescences, their color depends on the variety;
- large-leaved hydrangea - with round flower heads, slightly flattened on top, which can have different colors;
- panicle hydrangea - differs in pyramidal inflorescences of a white-cream shade, ripens in autumn;
- hydrangea Annabelle (tree type) - its inflorescence has a white tint.
All types of hydrangeas are susceptible to disease. If the leaves have lightened, most likely chlorosis has overcome her. This can happen due to a large number humus or lime in the soil. The flower is very sensitive to these substances.
Often liana is exposed to powdery mildew, it appears gray rot... You need to be very careful not to overdo it. nitrogen fertilizers, be careful with watering, first of all, during constant rains. Bordeaux liquid is used to treat diseases of petiole hydrangea.
This plant can be attacked by insects: spider mites, aphids and thrips. Aphids are usually harmful to plants planted in greenhouses. Insecticides are used to destroy it. With the onset of each season, you need to process the plant twice with an interval of 7 days.
Decorative qualities
All varieties of hydrangea are very beautiful and are widely used in the design of various landscape areas. This plant can be planted for the design of various garden buildings... Due to the properties of quickly adapting to new conditions, it will grow abundantly in a couple of years after planting. Wire support can be created to ensure proper growth. Thus, the vine will tightly cover the entire vertically created surface.
Stalked hydrangea flowers are white, but if desired, they can be painted in blue colour... To do this, you need to buy a special bluing agent that is sold at any gardening store. You can take aluminum sulphate and sprinkle it on the ground around the plant. The plant cannot be harmed by these means, and after a while its flowers will turn blue. Liana of this color will have interesting view in a decorative composition on the fence.
Placing a petioled hydrangea in a garden area, you need to know certain rules. Although the plant is not very demanding, it must be properly positioned for the flower to take root.
Subtleties of placement of petioled hydrangea:
- frost resistance: the plant is winter-hardy, it can withstand the climate of the middle zone without damage;
- lighting: hydrangea is very fond of light, you need to place it on open place, since it will bloom only when good lighting (grows very slowly in the shade and has small flowers);
- the ground should be moist, drained, in no case should you overdo it with watering.
This plant is not very demanding on the acidity of the earth, but it is recommended to add peat to it. You should not use lime soil, as the plant does not really like it and will grow poorly.
Since the climbing hydrangea covers the ground as it grows, like a huge carpet, it can be used to cover a certain area plot. For example, place in a rockery, land on alpine slide, it is in perfect harmony with stones. Thus, this curly plant can braid even a very large stone, creating unusual compositions of large flowers and leaves. On flat surface hydrangea grows very quickly and can be used to decorate a large flower bed. The plant can also be placed in an upright position to decorate a wall, stone fence.
The petiole hydrangea does not want to grow and develop on fences that have a mesh shape, therefore it does not live in such conditions for long. If you make a support in the form of a column or flat wall, the plant will grow rapidly and be very lush. If correct and timely pruning is performed regularly, a thick green carpet will form, covering the entire perimeter of the wall. This solution would be ideal for a summer residence.
Correct reproduction
Hydrangea propagation is carried out using 2 methods: by shoots and using a seed. The seeds must be planted in a container in which fertile soil was previously put in the fall. In the spring, young shoots are transplanted into open ground.
Reproduction by a vegetative method is carried out much more often. For it, you need to cut off green cuttings, which have one internode. The stalk must be at least 7 cm long. When the hydrangea is taking root, watering is carried out several times a day, and the plant itself should be covered to protect it from direct sunlight. The best period for planting is spring (April or May).
In open ground, you can plant seedlings that are at least 2 years old. When planting, a certain distance between plants must be observed (not less than a meter). First, a pit is prepared for planting with a size of 40x40 cm and a depth of up to 50 cm. If the hydrangea is planted in clay soil, the size of the pit should be increased. The next step is to prepare the drainage layer. Fill a layer at the very bottom of the prepared hole broken brick or gravel not less than 10 cm. After that, pour fertile soil on top (13-16 cm). Drainage in this case is mandatory, as the roots can rot. The root system needs to be straightened in the pits and covered with earth. The root collar should be at the same level as the ground surface.
Plantings should be watered abundantly. Each plant needs at least 20 liters of water. AT trunk circles add mulch in the form of peat or sawdust. She happens to be organic materialthat protects the earth. Mulch retains water in the ground, is able to protect plant roots and prevents weeds from breaking through. It is important to find the most appropriate place for planting so that the plant feels comfortable.
Hydrangea varieties Miranda
The petioled hydrangea Miranda is one of the more recent varieties that immediately gained immense popularity. This variety of hydrangeas differs from the main species by the presence of more decorative leaves, which have an uneven color of a yellow-cream or yellow-green hue along the edges of the leaves. Miranda has a white bloom that appears in the second half of summer. Growing on a support, it can reach 9 m in length.
Hydrangea Miranda (petiolaris) prefers to be in light partial shade, on fertile soil. The new leaves of the plant in the sun can burn severely. A shrub in solid shade will develop normally, but have slightly smaller leaves and will not bloom.
Like the main variety, hydrangea can be used both as a ground cover and in vertical decoration, decorating a wall or fence.
To breed given view hydrangeas can be done with the following methods:
- reproduction using layering;
- cuttings;
- division.
If the bush has multiple shoots, excellent seedlings can be obtained. To do this, you need to separate the recently grown shoots and shorten them to several buds, while cutting the roots a little and treating them with potassium permanganate. When the shoots have been planted in the holes, they need to be constantly watered for a month.
If you breed the Miranda petiole hydrangea, you need to use shoots no more than 15 cm long, they should be woody. To carry out this type of breeding, it is better to choose the first month of summer. From a shoot with 2 knots, you need to cut off the top, remove 2 lower leaves. Put the stalk, which is processed with a growth stimulant, in a box with sand and peat. Do not forget about the moisture content of the mixture, it must be closely monitored, and the container itself must be covered with a film. You can remove it when the hydrangea becomes stronger.
To breed a hydrangea using layering, you need to carefully press the lower branch tightly to the ground. The earth needs to be moistened and swollen. In the place where the branch touches the soil, an incision is made, which is mulched with peat. This operation is best performed in early May or August.
If you do not cultivate the soil before planting the petioled hydrangea, the cuttings almost always take root. This plant is more suitable for the southern regions. In the northern regions, it is necessary to better prepare the plant for winter.
It is very important to exercise correct protection bushes:
- 1 The petiolate hydrangea requires that dead and damaged shoots be removed in time. It does not need pruning, as it is well fixed in the soil with adventitious roots.
- 2 You can moisten the soil once every 1-2 weeks. This will be enough for the vine to develop fully. If the weather is rainy, they run shallow groundwater, watering at all can be omitted. If a severe drought occurs, then it will be necessary to increase the moisture content of the soil so that the hydrangea does not wilted.
- 3 When hard frosty days come, some of the shoots may die. To protect the plant for sure, you should cover vulnerabilities with help plastic film... If there is snow, you can use it as a pillow that will protect the roots of the plant so that they do not freeze. The rest of it will quickly recover when the first sunny spring days come.
Pruning is carried out for correct growth hydrangeas. Intensive feeding is often used. For the greatest coverage of the fence, walls, and other supporting elements, you should trim large increments. In order for the wall area to be covered as densely as possible with large beautiful inflorescences, you need to cut the vine in early spring, leaving some of the branches with only 3-5 buds. You also need to tie up the stem, as if directing it, and cut off the shoots that grow from it. In this way, shoots will appear on the sides and the crown will look very dense. During the growing season, it is also necessary to prune. Using the petioled hydrangea as a ground cover plant, pruning is not necessary, only sanitary.
To ensure the plant has a lush color and normal growth, it needs to be fed with organics and minerals. You can also purchase ready-made store fertilizers for vines. Such formulations contain iron and magnesium, thanks to which the bushes develop rapidly, and its leaves acquire a rich shade. Fertilizing is best before planting and during intensive development. Top dressing should be done several times throughout the season.
The first time you need to feed the plant in late spring - early summer. A mixture can be prepared from one part bird droppings by diluting it with 10 parts water. The soil is fertilized with mineral fertilizer, which includes carbamide, potassium nitrate, superphosphate (in a ratio of 1: 1: 2). Re-feeding should be carried out at intervals of every 14 days. In this way, beautiful petiole hydrangea seedlings can be grown.
Curly hydrangea is ideal for vertical gardening, because forms lush foliage, branches well and grows quickly.
Under the curly, it is customary to understand the petiolate hydrangea, although there are others curly species, but they cannot stand the winter cold. When favorable conditions liana can reach a height of more than 10 m. Flowers of white or white-pink color have a pleasant aroma, collected in loose corymbose inflorescences. The scent attracts insects, including bees, so the plant is a honey plant. Flowering occurs in June, July. Some varieties of petiolate hydrangea are distinguished by decorative foliage (Miranda variety). During the season, the vine grows by about 50-100 cm.
Care and cultivation of climbing hydrangea
Curly hydrangea prefers to grow in shade or partial shade. It develops best on acidic, moderately moist, well-drained soils. Liana absolutely does not tolerate soils with lime content.
Water about 1 time a week, abundantly, avoiding stagnant moisture. To retain moisture, the soil under the bush is mulched with needles, wood chips. From spring (from May) to autumn, complex mineral and organic fertilizers, which are laid out in the near-trunk zone and slightly dug up along with the ground. Fertilizers are applied 3-4 times per season.
To achieve maximum decorativeness, an annual spring pruning (before bud break). Shoots characterized by active growth, as well as excess shoots, are subjected to complete pruning. Only branches with 2-6 buds are left, while the shoots growing from these branches are cut off. Sick, frozen, dry branches are removed every spring. In autumn, the faded inflorescences are cut off. Pruning stimulates the growth of lateral shoots and promotes abundant flowering.
Healthy and strong young shoots are distributed over the support and fixed. At the same time, it is important to provide reliable support, which will not be a pity, since the petiole hydrangea tightly braids the support, literally digging into it, especially into a wooden one. You should not plant a vine next to a residential building, because she can tear down walls. A shed, a strong fence, a canopy, or a powerful tree are perfect as a support.
In autumn the leaves turn yellow, in October the leaves fall off. Stalked hydrangea is highly frost-resistant, therefore does not require winter shelter, but for the first 2-3 years young plants provide protection from cold weather. To do this, the soil around the plants is spud and covered with dry foliage. In very cold winters, the tips of the shoots can freeze slightly.
On a note
To tint the white flowers of petiolate hydrangea, it is watered with a special dye that is sold in specialized gardening stores or aluminum sulfate is poured around the plant.
Reproduction
Climbing hydrangea is propagated by layering, cuttings and seeds. It should be remembered that cuttings or those obtained by cuttings begin to develop actively only in the third year of life.
Cuttings are carried out in early summer. Parts of lignified shoots are taken on cuttings. Cuttings 15 cm long are rooted in nutritious soil from a mixture of leafy, turfy soil, humus, peat and sand. Before planting in the ground, the base of the cuttings is treated with a composition to accelerate the formation of roots. Cuttings are planted at an angle. After planting, the cuttings are covered with foil or glass. The cuttings are kept in light shade, with regular soil moisture. Rooted cuttings are transplanted into open ground.
It is better to buy seedlings in the spring at the age of 2-3 years. The petiolate hydrangea is planted in a permanent place in spring (April) or autumn (September). Drainage, rotted manure or urea are laid at the bottom of the planting pit. When planting, the root collar should remain at ground level. Plants are planted at a distance of 1-1.5 m from each other. After planting, provide abundant watering and mulching of the soil.
Dividing a bush is not always possible, because mature bushes do not need replanting, except if necessary. Share the bush better in spring, each separated part must have growth buds. Before planting in the ground, the roots are shortened, the shoots are pruned, leaving 3-4 buds on them. Then the delenki are planted in a prepared hole, watered abundantly and mulched the soil.
Reproduction by layering is carried out in early May or August. The lowest branch is bent to the ground, placed in a pre-dug groove so that top part escape was above the surface of the earth. Before deepening in place, where the branch will come into contact with the ground, make a small oblique cut. The branch is fixed with pegs and watered. The cuttings are separated from the main bush the next year, in the spring.
Using
Petiolate hydrangea is used for vertical gardening of buildings different types, as well as as a ground cover plant.
Diseases and pests
May be affected by gray mold, powdery mildew, suffer from spider mites.
Hydrangea curly in photos
The petiole hydrangea is a unique variety of garden hydrangea that is fundamentally different from the tree or panicle hydrangea... It does not have a trunk and does not need careful maintenance; the only thing that the owner of this plant must provide is conscientious watering and a space, preferably free from weeds. Otherwise, instead of a chic carpet, the gardener will receive a carpet path with many holes and scraps of unsightly weeds sticking out from everywhere.
Description of petiolate hydrangea
Stalked hydrangea is a type of garden hydrangea that does not have a solid trunk, and its structure resembles not a bush, but a liana.
Hydrangea of \u200b\u200bthis type is capable of reaching the height of a four-story building.
Is this species frost-resistant? Yes, but young plants still need to be covered with spruce branches, because during the cold season, immature sprouts can freeze.
Photo of varieties of petiolate hydrangea
The most common varieties of petioled hydrangea are the following options:
- hydrangea petiolate miranda. This plant variety is capable of rising to a height of up to ten meters. The flower has wide, pointed leaves of a dark green color with pale white veins in the center. This variety has an incredibly sweet aroma. Habitat Belarus;
- hydrangea petiolate curly liana. A flower with umbrella-shaped inflorescences white, with the help of special dyes, you can give the colors the shade you want;
- hydrangea petiolate cordifolia. The flowers of this plant literally smell like honey, and the inflorescences are small panicles with small flowers along the edges of which there are larger white flowers;
- petiolaris hydrangea. Highest grade. It reaches a height of 25 meters. It can creep along the ground with a green carpet, or it can climb trees. This variety is preferred by landscape designers.
All these varieties enable the gardener to create in his garden, given great opportunity feel like an artist, show your individuality and let go of fantasy. - high-moor peat,
- sand,
- soil that was removed along with the sprout
Hydrangea petiolate, planting care
If the hydrangea was kept in a container before planting, then a planting hole should be dug twice the size of the container.
The most suitable soil composition is considered to be a mixture of:
in a ratio of 1: 1: 1.
If you add mineral fertilizers, then the root system of the plant will develop at maximum speed.
The basis of care is watering and feeding. The first year, it is necessary to thoroughly fill the soil, because the root system is not able to absorb enough moisture from the ground. Read about and how best to propagate this type of hydrangea.
The soil should be fertilized four times a year, this is also due to the inability of the petiole hydrangea to self-feed. The plant is incredibly susceptible to damage of various kinds pests, therefore, it should be processed every season.

The price of petiolate hydrangea seeds
The petiolate climbing hydrangea belongs to a group of very valuable plants used for vertical gardening. The beauty of this magnificently blooming liana has long been appreciated by the inhabitants of the Far East - it was from there that this beautiful flower, attracting attention with its huge white inflorescences and delicate honey aroma.
Description
Stalked hydrangea is a perennial climbing liana (the length of its shoots is 25 meters) with a very beautiful and abundant flowering... With the help of numerous aerial roots and suction cups, the vine can braid any support with its flexible lashes. During flowering, the surface covered with this flower looks irresistible. Because of their decorative properties petiole hydrangea is used for landscape design, decorating the facades of houses, fences, terraces, pillars, balconies, trellises, pergolas and for planting on the lawn in the form of columns, pyramids, etc.
Please note: petioled hydrangea has unique ability - its flowers can be dyed in any color using ordinary dye.
It is cultivated climbing plant was in 1868. Modern hydrangea has been improved by scientists and has a set of qualities that make it easy to grow for many years. Lianas, spreading for many meters in different directions, are wind-resistant, easily tolerating unfavorable external factors. Hydrangea can grow in any climate and every year it is overgrown with abundant lush green foliage and hundreds of fragrant flowers. The leaves are elliptical, smooth above, covered with hairs below. Already in the middle of spring, the green crown densely covers the lignified branches. 
With the arrival of autumn, the foliage becomes golden, and by November it completely falls off. In winter, the dark brown shoots are adorned with countless buds. This plant is frost-hardy - it easily tolerates winter and cold. The shrub can even withstand 30-degree frosts.
Important! AT wildlife petiole hydrangea practically does not occur. This species is listed in the Red Book.
Curly petioled hydrangea is a whole varietal group of various liana-like plants, which differ in color of flowers, structure of leaves, and resistance to weather conditions. Based individual characteristics a particular hydrangea, you can choose a variety suitable for the growing region.
Please note: the climbing hydrangea is also known as climbing hydrangea.
Hydrangea lovers also choose this flower for its long flowering. The first flowers bloom in June and delight the eye until the end of summer. The inflorescences are very large, consisting of numerous flowers, reaching 25 centimeters in diameter. They abundantly cover the entire length of the vine. The branches adhere firmly to the surface on which they grow. However, an interesting fact is that hydrangea prefers solid walls or fences, but does not grow well on mesh supports.
There are relatively few flowers in the first years of hydrangea life. But with each subsequent season, the plant begins to form more and more lush buds. They bloom in pure white color, which gradually acquires pink tint and lasts until autumn.
Fact: there is no longer such a vine that can survive the winter even in Siberia and bloom so beautifully for ten years in Russia.
The most popular varieties in Russia:
Growing features
For the first planting of petiolate hydrangea, two to three year old seedlings are suitable. The planting process is not difficult. It is more important to find a suitable place for further growth of vines and enrich the land.
Seat selection
Since the liana hydrangea usually grows on some surface, the site is selected based on what kind of support the plant should braid. Hydrangea grows calmly in light partial shade, but the sun should still fall on its parts - then the flowering will be more luxurious. But in direct sunlight, it is better for the plant not to grow - the hydrangea withers, dries up, and its flowers become small and rare. There should not be any big trees - this will cause competition for moisture in the soil. It is necessary to choose a place for planting hydrangeas very carefully, taking into account in advance how the shrub will look in mature age... It is unlikely that it will be possible to transplant it in the future, since the plant takes root very well in the ground, and it will not be possible to pull it out without damage.
Like the vast majority flower plants, hydrangea prefers light, drained and acidic soil (pH 4.5 to 5). She must also be very fertile. You can nourish the soil with humus or compost. It is important to avoid excess calcium in the soil. If this is the case, then high-moor peat and leafy soil are introduced into the soil. And if the earth is very dense, heavy, then you can loosen it with the help of sand.
Landing
Hydrangea cuttings are best planted in early spring or in the fall. If the planting is carried out in a group, then the cuttings are placed at a meter distance from each other.
Please note: there are plant species on sale that can easily be confused with petiolate hydrangea - liana. This is an unusual hydrangea and a hydrangea-like schizophragma. These flowers overwinter much worse in the middle latitude of Russia.
The root system of the hydrangea is very powerful, highly growing. Therefore, a pit for a seedling is prepared deep and voluminous (50 centimeters in depth and 40 centimeters in diameter). The bottom of the hole should always be covered with a drainage layer - expanded clay, pebbles, crushed brick. From above, the drainage is covered with fertile soil, which at the time of planting should be well moistened. The seedling is placed in a hole, carefully spreading the roots along the bottom. The rhizome will grow mainly in breadth. The voids are filled with dry earth and compacted. The seedling does not need to be planted too deeply - the root collar should be on the border with the surface.
Plantings are watered abundantly with water and mulch. Mulch - perfect option preservation of soil moisture.
At first, young seedlings are especially in need of care. And any change in the weather can harm fragile plants. The first two years of the life of the seedlings will be spent on their development, the growth of roots and surface parts. Therefore, do not be surprised that the plant will have no time to bloom. The abundant color will go a little later.
Fact: petiolate hydrangea is the longest plant used as a decoration. Sometimes it can reach 12 meters in height.
Reproduction
If there is a desire to increase the number of hydrangea vines, it is not necessary to go to the store for new seedlings. You can grow a whole garden of hydrangeas on your site with your own hands. This flower reproduces well by layering or cuttings.
Fact: The survival rate of hydrangea cuttings is more than 90%.
Cuttings are harvested in the spring. They are cut off before the plant wakes up, and life processes begin to take place inside it. Shoots are cut from the apical branches, so that there are several buds on each cuttings. The cuts must be made at an angle.
The twigs are placed in sand mixed with peat. To stimulate root formation, you can spray the cuttings with a specialized solution. The seedlings are placed in a warm and humid environment. You can arrange a mini-greenhouse by covering the container with hydrangea with a bag or plastic and put it in a warm and bright place. Until the cuttings become overgrown with roots, they need to be regularly ventilated and watered. It is important to ensure that condensation does not form inside the greenhouse. Excessive moisture can lead to the development of fungus. When the cuttings are rooted enough, they are planted in a permanent place.
Hydrangeas can also be propagated by layering. This method is less laborious, and the result obtained is quite impressive. In spring, shoots are determined on the plant, which will become the parents of new plants. These shoots bend to the ground and bury the ends in the ground to a depth of 10-15 centimeters. So that the branch does not "shoot", it is pinned with a special clothespin. 
The soil for the outlets must be dug up in advance, moistened and supplied with fertilizers. Shoots must be free of foliage. Over the summer, the ends will overgrow with roots. And already in September they are separated from the mother plant with the help of a secateurs. Young seedlings are left in the same place or transferred together with a clod of earth (so as not to damage fragile roots) to a new site.
Please note: you can propagate by layering both in May and August. However, with autumn breeding, rooted cuttings must overwinter indoors, otherwise young seedlings will freeze in cold soil.
Features of agricultural technology
This curly summer plant grows well and blooms only with high agricultural technology - deeply cultivated soil, applying a large amount of fertilizer, regular watering, pruning, etc. As a support for shoots for the most part use a cord.
Top dressing
Fertilizing the soil is a very important technique, but not the only one in order to obtain nutrition for plants. Regulate admission nutrients it is possible with the help of loosening, irrigation. If all the conditions for healthy plant growth are met (plants receive the optimal amount of light, moisture, heat and air), then fertilizers are used to stimulate the development of hydrangeas. A perennial vine that has limited area nutrition is very depleting of the soil. Therefore, you need to feed the plants regularly.
During the growing season, you can feed the hydrangea with mineral and organic compounds, in dry and liquid form, dissolving them in water, combining them.
The first portion of fertilizer is applied to the planting hole. AT next time seedlings are fed only after they have rooted and started to grow. Then during the flowering period. It should be kept for about 2-3 weeks between feedings.
After the end of the color, closer to autumn, the hydrangea is fed in last time... Compost or humus is poured under each bush.
Ammonium nitrate, potassium salt, superphosphate (dissolved in water) are used as liquid top dressing. You can also arrange dry fertilizing with minerals. Dry compositions are crushed and mixed with organic matter or peat. The mixture is spread on the ground just before rain or watering.
For plants to have a rich green crown, organic fertilizers should be placed under the root. For this, mullein, manure or bird droppings are bred, mixed with copper sulfate... And to strengthen the shoots and save them from the harmful effects of pathogenic microflora, monthly treatment of the bushes with a weak solution of manganese will help.
Fact: feeding mineral fertilizers have a good effect on the growth and flowering of ornamental plants.
Immediately after planting, the seedlings will first develop root system, while the outside of the plants will be at rest. An adult hydrangea grows its apical part much faster, up to 50 centimeters per year.
Pruning
All ornamental plants require formation for more nice looking... To maintain a clear pattern, the direction of growth, the haircut must be carried out regularly. Inflorescences are formed, as a rule, on young shoots, while old ones only only compact the planting, make it unkempt and neglected. The overgrown hydrangea blooms poorly and unevenly. The plant reacts very well to pruning and grows rapidly with new vegetation after the procedure.
In early spring, before the start of sap flow, the branches are pruned, which grow "in the wrong direction", as well as damaged, dried out, sterile. Shoots are cut, leaving 5-6 buds on the bases. Do not get carried away with cropping, otherwise you can ruin the whole composition. And if the hydrangea spreads on the ground, then pruning is not at all worth it.
Note: all parts of the petiole hydrangea plant are considered poisonous, since they contain cyanogenic glycosides.
Real, intensive pruning begins only in the third summer. It is known that petioled hydrangea grows very slowly, and in the first two years the apical part of the plant practically does not grow. From the third year, the vine begins to gain momentum. Now its shoots will grow rapidly, and if a bush is not formed in time, then soon numerous hard branches will cover the entire surface and spread to the adjacent territories. The branches must not only be cut off, but also directed in the “right direction” with the help of a garter.
Sanitary pruning should be done during the season, removing all diseased and broken branches. And at the end of summer, all faded buds should be removed from the bush. So you can guarantee a lush color next season.
Please note: for haircuts, they use trellis shears, the blades of which are recommended to be lubricated with machine oil. This allows for smoother, smoother cuts and makes work easier.
Watering
Liana hydrangea grows well in a humid environment. But not flooded - the fungus will grow. Water for irrigation should be soft and warm. It is ideal to use rainwater. The number of waterings in moderate summer is twice a week.
Irregular watering will deplete the plant. The flowers will be few and small, and the foliage will be lightly colored.
In hot periods, it is useful to spray the shrub with water from a spray bottle.
Please note: for each hydrangea bush, you need to spend 30-50 liters of warm water.
Wintering
As already mentioned, the curly petiolate hydrangea is absolutely not afraid of the winter cold. This frost-resistant plant easily tolerates bad weather, and in the spring it dissolves numerous buds. However, young seedlings that are less than three years old should be protected from cold weather using a covering material. For this, the shoots are bent to the ground and covered with spruce branches. The land under the bushes is abundantly mulched with sawdust or old grass.
Protection against diseases and pests
The petiolate hydrangea does not get sick with proper adherence to agricultural technology. If the soil is oversaturated with nitrogen, it can cause chlorosis, in which the leaves become pale with yellow veins. With this disease, an urgent need to reduce the amount of nitrogenous matter. For this, potash-phosphorus fertilizers are applied.
