Best of all hydrangea feels on subacid soils. A tree-like variety of it is easier to tolerate the presence of lime in the soil than all the others.
In warm regions of the tree hydrangea is desirable to place in the openwork penumbra. The shrub will develop well in the sun, but in this case it will have to be frequently and abundantly moisturized. In more northern regions and the middle lane, the beauty will be more comfortable in a place with good illumination.
The planting dates are also associated with the climatic zone of growth. So, in the south of Russia, you can land in spring and autumn, and the rest of the territory is desirable only in spring time.
- First of all, it is necessary to prepare a landing hole. Its parameters should be approximately in the region of 30-40 cm, the exact dimensions depend on the diameter of the earthy ball with the rhizome,
- For the full life of the hydrangea, you need a sufficient amount of moisture and nutrition, so be sure to pour a little sand, compost and humus into the recess,
- Before planting, the roots are carefully inspected, removing damaged, dried and straightening entangled. The length of all the roots should be approximately the same,
- During planting, make sure that the root neck is not in any way covered with soil and located at ground level,
- To make the root system easier and faster to take root, before planting, hold it for several hours in heteroauxin, and then immediately land on a permanent place,
- After planting, water the plant with plenty of water, and after it is absorbed, pour out the settled earth,
- The bushes during the first weeks after disembarkation necessarily protect from direct sun and strong gusts of wind.
Difficulties in the rooting process can arise if we allow the slightest drying of the root system. The same will negatively affect the further growth of the bush.
How to properly care for hydrangea
In order for hydrangea tree to develop normally and bloom profusely, it needs abundant watering, regular feeding, formation and mulching.
Particular attention should be paid to watering hydrangeas. All varieties of this ornamental shrub love abundant watering. Water at least once a week, while the bush requires 15-2 0 liters of fluid. When heavy rainfall is permissible to moisten the plant once a month.
During the vegetative season, hydrangea is fed 4 times:
- First of all, it is during the period of activation of the growth of shoots. Fertilize a full complex of minerals and trace elements, while the concentration of nitrogen should slightly exceed all others,
- The second time is fertilized at the time of formation of buds with superphosphate and potassium sulfate,
- Two subsequent spend throughout the vegetative season, in composition, they are similar to the previous one.
An important procedure for the care of hydrangea is mulching. The soil under the bushes is covered immediately after the shoots start to break out of it. Sawdust, peat or wood chips can be used as a material, its layer should be 5-8 cm. Mulch should not be in contact with the trunk and shoots, as this may lead to rotting.
In addition to mulching three times per season, the soil under the plant must be loosened.
Tree Hydrangea Breeding Methods
Tree hydrangea breeds quite easily. Three methods are used for this purpose:
This is an effective way, the percentage of rooting, subject to certain requirements, is almost 100%. Planting material can be prepared in early June so that, on the basis of the cutting, a part of the last year’s sprout remains, or in July until the stems are lignified, while preferring the branches of the current year.
- Each stalk should have 2-3 pairs of leaves, which must be cut to 1⁄2,
- Cut the planting material with a root growth stimulator,
- Prepared cuttings should be planted in a loose, well-fertilized and moistened soil in a shady place; greenhouses are suitable for this purpose. When planting, the cuttings are buried in the soil for a couple of lower buds. Cover it with a plastic cup and leave for 20-30 days.
A good way to breeding is breeding and layering. In the spring, a healthy, strong shoot gently bends down to the soil in the small depression made and sprinkled with a thin layer of earth. For reliability, secure it with a wire stud. The free end of the shoot is slightly bent up.
Throughout the summer (this is about 3 times), the ground is filled into the groove, watered regularly, preventing drying and over-wetting. A year later, the already ingrained seedling needs to be separated with a secateurs from the mother bush, and then planted for growing in a shady place.
Shrubs obtained from cuttings and cuttings to a permanent place transplanted after 1-2 years. Their bloom will please you only in the fourth year.
The easiest and fastest way of breeding is dividing the shrub. The plant is dug up and divided into parts with a sharp spade or ax. The resulting parts are planted in the landing channels. It is advisable to subject them to pruning immediately. In the future, they require the same care as adult plants. The hydrangeas divided in this way take root without problems.
How to trim a hydrangea
There are three types of trimming:
- Forming is carried out at the very beginning of spring and makes it possible to preserve the decorativeness of the bush for many years. Thanks to her, the plant produces powerful shoots, which subsequently give large inflorescences. Its meaning lies in the fact that the hydrangea forms floral brushes on the shoots of the current season. But gradually the shrub becomes too thick, there are too many shoots, the food is unevenly distributed and flowers are the first to suffer. All strong shoots of hydrangea are removed, leaving 3-5 buds, weaker to 2-3 buds. Try to keep the uppermost left buds facing out, not inside the bush. In this case, it will be evenly lush and not thickened. After formation, the plant must be fertilized with a full mineral "cocktail".
- Sanitary pruning involves the removal of all broken, dry, diseased and underdeveloped shoots. In the following year, plants treated in this way should be subject to formation.
- Rejuvenating pruning allows you to rejuvenate old shrubs. To do this, absolutely all the branches are cut at a height of half a meter from the ground. Flowering is possible only a year after the procedure.
Pruning should not expose the young, not flowering before, the bushes under the age of 4 years.
Competent hydrangea transplant
- It is best to hold this event in early spring, as soon as the snow covers. In the south, as already mentioned, it is possible to do this in the fall,
- Transplantation should be carried out without damaging the earthen clod around the roots. At the completion of the procedure, the bush is well watered,
- It is much more convenient to replant a more compact bush than a bulky one. Therefore, it is useful to combine transplantation with formative trimming,
- If while digging the earthen room it was not possible to preserve integrity, carry out a more radical pruning, otherwise the plant may simply die,
- 2-3 weeks after transplantation, hydrangea must be rescued from direct sunlight,
- In arid hot weather the shrub is well watered,
- Fertilize a transplanted plant can be no earlier than a month after the relocation. It was at this time that the growth of shoots resumes, and this is a signal of its successful rooting.
Preparing for the winter
Hydrangea tree has good winter hardiness. Even after a very harsh winter, the damaged plant quickly recovers and blooms. This quality makes the culture quite common throughout Russia.
However, for reliability in the northern regions, and better in the middle lane, it is better to prevent a possible problem, i.e. cover the plant for the winter. This simple procedure will help him transfer the winter time without damage.
For this, a wooden stake is driven in close to the bush, to which all shoots are firmly tied. Top sprinkler spruce branches. Can be used instead of lapnika covering material.
Tree hydrangea: characteristic
Description Hydrangea arborescens (Hydrangea arborescens) has the following: refers to deciduous shrubs, usually grows to 1.5 m (in America it can reach 3 m). The shoots are tubular, straight, the leaves are green, large (in the shape of an ellipse), covered with a glaucous pubescence at the bottom, and serrate on the edge. Blooms profusely with large (15–20 cm in diameter) shield inflorescences (white and cream with greenish hues) from July to October. It is characterized by winter hardiness and fast growth of shoots (from 20 to 30 cm per season).
Tree hydrangea became the basis for breeding a large number of varieties with high cold resistance (with different flowering periods, size of inflorescences, shades, etc.). The most popular are:
- Annabelle - blooms from June to September, dense round white inflorescences (25 cm). The diameter of the crown - 3 m, height - 1-1,5 m. The leaves fall green in autumn,
- Pink Annabelle - selection variety bred pink color,
- Strong Annabelle - possesses strong shoots capable of holding heavy balls of inflorescences without tying,
- Sterilis (Sterilis) - has a very abundant flowering, fruitless. It can reach two meters in height. Flowers initially have a greenish tint that changes to a snow-white, blooms from July to October,
- Hayes Starburst - large inflorescences of terry flowers of white shades, blooms until frost,
- Pink Percussion - with small inflorescences (up to 10 cm) pink shades.
Hydrangeas grow well in any light, but practice has shown that:
- under the bright and scorching sun (especially in more southern regions) the size of inflorescences decreases, plant growth slows down,
- thick shadow leads to the fact that the inflorescences do not develop, become rare, flowering decreases.
Soil for hydrangea tree
The composition of the soil hydrangea picky. Most of all, the plant prefers fertile loamy soils with good drainage and high acidity (all mycotrophic plants need soil fungi). Hydrangea tree of all hydrangeas best tolerate the presence of lime in the soil. The soil should not be dense, it should pass air and water well (by adding sand, it should be taken into account that water in such a soil will go to a depth faster). With a lack of acidity, if desired, it can be enhanced with special additives (sawdust, softwood, brown peat, etc.).
When is it better to plant a tree hydrangea
Tree hydrangea can be planted in spring and autumn. In each case, there are pluses. The main plus of the autumn planting of hydrangea is that the planted plant will begin flowering with the onset of spring. Planted in the autumn of large bushes that have a developed root system. In the more northern areas, an autumn disembarkation should be carried out better in September; a shelter should be prepared for wintering.
Planting in the fall:
- does not take much time
- harden hydrangea, increase its disease resistance.
When planting in the spring, you need to wait until the end of frosts (taking into account different regions, this may be April or early May). In any case, the soil should be well heated. Young seedlings are planted with an open root system.
Planting hydrangea tree spring has advantages in that seedlings:
- take root quickly
- less sick
- better winters.
Selection of seedlings for planting
Saplings are sold with an open and closed root system (in special containers). Choosing seedlings, you should pay attention to:
- on plant height (should be from 50 to 100 cm),
- on shoots (there should be 2-3 live shoots),
- on the kidneys (must be whole, large and fresh),
- on the bark (should not be damaged).
In saplings with open roots, the root system must be developed, whole, without dryness and rot. Their length should be at least 30 cm. If the roots of the seedling are hidden by the container (visual inspection is not available), you should find out when the seedling was transplanted (a recent transplant is undesirable). Immediately before planting, you should examine the earthen room: bright young roots should be visible on it. Gardeners recommend planting three or four year old plants.
Saplings with open roots should be purchased immediately before planting (if for some reason planting is not possible, the seedling should be placed in a dark place and the roots should be kept moist).
The scheme of planting seedlings hydrangea
Before planting a hydrangea tree in the garden, it is necessary to correctly calculate the planting scheme. Need to consider:
- The crown diameter of an adult hydrangea is 2-2.5 m. When planting several hydrangeas, care must be taken that the radius is at least 1-1.5 m (this will allow the plants to develop freely and will facilitate the approach to care),
- it is advisable not to plant the hydrangea next to the fruit trees (their roots quickly dehydrate the soil, suppress and prevent hydrangeas from developing).
- preparation of pits. The size of the pits depends on the size of the seedlings (from 25 cm to 50 cm deep and 50-75 cm wide). The larger the plant, the deeper the fossa (the root system of the seedling should fit freely)
preparation of seedlings (before planting hydrangea in spring, open roots for a couple of hours should be placed in a warm solution of potassium permanganate, cut long roots. With a closed root system, soak it with water),
creation of drainage (put a layer of expanded clay, rubble and sand at the bottom of the fossa),
the creation of a special regime of the soil at the landing site. In the pits (1/3) lay the mixture of humus, peat, compost (1 x 1 x 1) or the mixture for azaleas,
planting the seedling in the fossa (root neck - at the level of the edges of the fossa), straightening the roots (if the roots are open). With a closed root system - it is necessary to remove a clod of earth from a container and, without touching it, place it in a pit,
falling asleep with soil, abundant watering with warm separated water (no less than a bucket per well), filling the ground and lightly tamping the soil around the seedling (not to damage the roots),
- mulching for 10-15 cm (a mixture of sawdust, pine needles, straw, paper, burlap, expanded clay is best suited). This will allow better retain moisture, protects against weeds, protects from cold weather.
The scientific name of hydrangeas - "hydrangia" - directly indicates the love of this plant for water. The root system of hydrangeas grows in a horizontal plane, and when the groundwater is deep-seated or during the dry season, the lack of moisture immediately affects the developed aerial part.
For the normal development of hydrangea must be watered:
- regularly. The plant should receive at least 30 liters of water weekly. Mulching the tree circle in combination with natural rainfall will help reduce water consumption,
soft water without chlorine (hydrangeas especially like rain water). Therefore, water for irrigation needs to be harvested in advance - to defend water supply and / or collect rain in the tank,
non-cold water (20-23 degrees Celsius),
in the evening or in the morning
without watering the inflorescences when watering (water makes them heavier, and shoots may break).
How to fertilize tree hydrangea
In the first year after planting, fertilizer for tree hydrangea is not required to be applied to the soil (enough nutrients are put in the hole). In the future, it is necessary to regularly trim up at least three times per season:
- with the advent of the first shoots (April-May) - a complex fertilizer (“Fertika”, etc.) or a mixture of superphosphate and potassium sulphide (30 g per sq. m) and urea (20 g per sq. m),
with the beginning of budding (mid-June) - a mixture of potassium sulphide (40 g per sq. m) and superphosphate (70 g per sq. m). A good multivalent nitrogen fertilizer will be a mullein infusion (7 kg of manure per 3 liters of water to insist 4 days) - 1 l per bucket of water,
during flowering (end of August) - organic fertilizers (compost, rotted manure).
Trimming Tree Hydrangea
As practice shows, it is easy to trim a tree hydrangea correctly, but this must be done from the first year after planting (provided that the plant is 4-5 years old).
Pruning allows you to stimulate growth, increases the number and size of inflorescences. The main time for pruning a tree hydrangea is spring (from the moment when the snow melted until the beginning of the leafing).
In the spring, the following types of pruning:
- sanitary (after wintering, dried, frozen or broken shoots are removed),
rejuvenating (for plants aged 5-6 years and older - cutting under the base of old shoots with weak shoots),
thinning (struggle with thickening - removal of small, weak, growing in the direction of the center and other shoots).
In the fall, only pruning pruning is performed (last year's shoots). Some gardeners recommend the main pruning in autumn. Гортензия древовидная плохо переносит обрезку перед зимовкой, и обрезка осенью нежелательна – может не оправиться и замерзнуть зимой.
Размножение древовидной гортензии
Practicing five ways how to propagate tree hydrangea.
The least used method is reproduction by seeds. In this way, the cultivars of hydrangeas do not multiply - they lose their main characteristics. In addition, the germination of seedlings requires at least three years. The second method of breeding hydrangeas, the most common - grafting. There are two ways of cutting hydrangeas: lignified and green cuttings.
In the first case, grafting occurs in early April (before bud break). The seedlings thus obtained are of higher quality (more than 70% of them take root). From the pruned shoots, cuttings with two buds are cut — with an oblique cut below the bud and straight (2-3 cm from the upper bud) above. The cuttings should be planted at an angle of 60 degrees into a mixture of peat and sand (the lower bud should be deepened by 3 cm), kept under a plastic in a greenhouse and watered abundantly.
In the second case, grafting occurs in summer and autumn (best of all - mid-July, during budding). Cuttings are cut with two leaf nodes (tops with buds for cutting are not suitable). Lower leaves are removed, half is cut off from upper ones. Shank process 30 minutes "Fundazol" (10 g per bucket of water), then the lower slice - a root formation accelerator. Another option is to hold the cuttings in the dark for two hours in Kornevin, Zirkone, and Heteroaukin. Process the upper cut with green paint and deepen into a wet mixture of two parts of peat and one sand (to the top sheet). Cover with a jar (or a cut off part of a plastic bottle with a neck), water twice or more often a week. Rooted such cuttings about 25-30 days. The rearing of hydrangea trees is carried out already next spring after wintering.
The third method is reproduction by layering.
This is done before the bud breaks in the spring as follows:
- dig up the ground around the hydrangea and flatten it,
choose one of the lowest shoots, cut the leaves (from the ground up to 15 cm),
make a radial groove (5-10 cm deep), lay escape,
fasten the shoot with crutches (or press down with a stone), sprinkle with soil (the end of the branch is left outside, you can attach it to the peg) and moisten.
By the end of summer, young shoots appear on the slips, which need to be spud every 10 days. Separation of the layers can be carried out in late autumn or next spring.
Before planting a hydrangea tree by dividing the bush, pruned outdoor shoots and very abundantly watered. After that you need to do the following operations:
divide the bush (in two or more parts),
trim the ends of the roots
plant separated bushes in a prepared place.
This breeding method is used mainly for transplanting hydrangeas. The fifth way is to fall down the sapling in the autumn (something between the mean how to divide the hydrangea bush in the spring and multiply the layering). For landing the prepared trench with an inclined bottom is used. The seedling is placed so that the roots are more deep, the shoots are higher. First, the root is buried, the shoots are fanned out and buried too. You can put a layer of peat on top (so that the plant does not freeze out in winter). In the spring, after warming the land, buds on the buried shoots will come to life and grow. At the end of the summer, the hydrangea needs to be dug out and separate new shoots, as a result we get several seedlings (up to 10) with a formed root system.
Major pests and diseases of hydrangea tree
Tree hydrangea, with proper care, is rarely affected.
Increased humidity, lowering the temperature can provoke infection with fungal diseases (especially if there is a source of infection) - false and true powdery mildew, white and gray rot. First of all, leaves and flowers are affected. Oxychloride copper (HOM), Bordeaux liquid, Fundazol, Chistotsvet and others help against fungal diseases.
Among the pests, garden snails, spider mites and aphids cause the greatest damage:
- snails affect buds, buds, young shoots and leaves (especially dangerous in early spring, when they climb into wintering bushes). The fight is carried out by manual assembly, the layout of traps with chemicals (metaldehyde or "Thunderstorm") near the hydrangea,
spider mite infects leaves, shoots. Infection occurs with increased air dryness. At treatment various insecticides and acaracides are used (“Akarin”, “Thiofos”, “Molniya”, “Vermitek”, etc.). Of the popular methods of struggle - treatment with soap and water, mineral oil,
Aphid sucks juice from young shoots, buds. Used in the fight against it "Inta-Vir", "Aktellik", "Fitoverm" and other drugs. From popular methods - processing infusion of garlic (200 g of crushed garlic in 10 liters of water to insist 3 days, add 40 g of soap).
Tree hydrangea: wintering plants
Tree hydrangea has sufficient winter hardiness. But it’s still not worth the risk (even in mid-latitudes strong frosts are possible in winter), all the more preparation for winter does not take much time and effort:
- spud, add peat and mulch (in the near-stem circle - 25-30 cm),
to bind shoots (branches of the tree hydrangea do not bend down to the ground - they can break off), drive a few pegs around the bush, attach a spruce fir twig, wrap with agrofibre (lutrasil, spunbond, etc.) and tie around.

Hydrangea Tree - description
Hydrangea tree is a shrub in height from 1 to 3 m with a rounded crown and slightly pubescent shoots. The leaves of the hydrangea tree elliptical or ovate, from 6 to 20 cm long, with serrated edges and a heart-shaped base, bare from the bottom side of the plate. The upper side of them is green, lower gray. A few infertile flowers with a diameter of about 2 cm, together with small fruit-bearing flowers, are collected in shields up to 15 centimeters or more in diameter. At the moment of opening, the white flowers have a greenish tint, then the proselen disappears, and by the end of flowering the inflorescences turn pink. The fruit of the hydrangea tree is a box up to 3 mm. The plant blooms profusely and continuously from the first half of July to mid-autumn.
Culture is distinguished by its rapid growth, love of moisture, demanding of soil composition and winter hardiness. This species is easier than other hydrangeas, tolerates the presence of lime in the soil.
When planting a hydrangea tree.
Planting time of hydrangea tree is chosen taking into account the climate of the area. In the north, it is better to plant it in early spring, before the start of sap flow, as soon as the garden thaws the soil, and in areas with a mild, warm climate, you can plant hydrangea both before the buds swell and after the leaf fall.
How to choose a place for a plant? Hydrangeas prefer well-lit areas in the morning, which after dinner are in the shade. Hydrangea tree does not like wind: its flowers in blown through places quickly fade. The soil needs a moistened plant, so do not plant it close to trees and shrubs, so that they do not absorb moisture from the ground for hydrangea: the distance from a tree hydrangea bush to any other plant should be at least 2 m.
How to plant a hydrangea tree.
The best planting material is three to four year old saplings of hydrangea tree. When buying seedlings with an open root system, pay attention to its condition, but it is better to purchase planting material with closed roots. Before planting, the seedling is plentifully watered, taken out of the container and shortened its roots to 20-25 cm. If rotted or dry roots are found, it is necessary to cut them as well.
When they are planted in poor soil, they dig a hole with a diameter of about 50 and a depth of 65-70 cm, but if the soil is fertile, then the depth may be less - about 50 cm. In general, the size of the hole depends on the size of the seedling root system and the amount of land on it . In the center of the pit, place a mound of pre-prepared soil mixture of humus, black soil, sand and peat in a ratio of 2: 2: 1: 1 with the addition of 50-60 g of complex mineral fertilizer. Place a seedling on a mound, spread its roots and fill the remaining space with the same nutrient soil mixture. Then tamp the surface of the wheel circle and pour the plant abundantly under the root.
Growing hydrangea trees in the garden.
Tree hydrangea in the open field requires regular and abundant watering, especially in the dry hot period. In addition, you will need to loosen the soil in the circle of the tree and remove weeds, apply fertilizing to the soil, cut in hydrangeas and protect it from diseases and pests.
Watering of hydrangea trees is carried out 1-2 times a week with water at a temperature of 20-25 ºC, pouring at least 3-4 buckets of water under each plant. If the plant lacks moisture, its leaves droop and begin to turn yellow, the flowers dry up, and the hydrangea loses its decorative effect. Therefore, make sure that the soil in the bore circle does not dry out. After watering or raining, the surface is carefully loosened, taking care not to damage the root system, which is not shallow, while removing weeds. To protect the soil from the rapid loss of moisture, you need to mulch the surface around the plant with a layer of peat or humus, in this case you will have to water and loosen the soil and weave much less often - about once every 10 days.
In order for hydrangea to be attractive throughout the growing season, it is necessary to feed it with both mineral and organic fertilizers. In early spring, a handful of Kemira flower is spread in the circle of the tree, which contains not only the nitrogen, phosphorus and potassium necessary for each plant, but also a group of important trace elements. The second dressing, consisting of 30 g of potassium sulfate and 50 g of superphosphate per plant, is added during the budding period. In the future, you can fertilize another 2-3 times, but be careful with nitrogen, because its excess leads to a steady green tint in the colors of hydrangea. In addition, plants overfed with nitrogen do not winter well.
2-3 times in the spring, watering the soil in a circle around the barrel and spraying the crown with a weak solution of potassium permanganate. This is done to enhance the strength of the shoots of tree hydrangeas, which can not withstand the severity of a large number of large inflorescences. You can, of course, tie up branches to the support, but this will not add to the plant attractiveness.
Of all species of the genus, hydrangea is the most unpretentious and cold-resistant, but new plant varieties brought from nurseries in warm regions require dry hilling and light shelter before wintering. Hydrangea bushes younger than four years are covered with foliage or spruce branches. It is advisable to tie the branches of the bush together for the winter so that they do not break under the weight of snow. But even if the plant suffers from frost, hydrangea is tree-like in spring, it recovers rather quickly.
Pruning hydrangea tree.
Hydrangea tree forms inflorescences on the shoots of the current year. The first four years after planting the plant is not pruned, but later pruning is carried out twice a year, in spring and autumn. The main is the autumn pruning, during which all faded buds are removed.
If the hydrangea is not cut, the bush becomes too thick and has a sloppy, neglected appearance. In the spring, before the start of sap flow, they do a sanitary cleaning of the shrub, removing weak, thin, frozen, dried, damaged and thickening shrubs, that is, weakened, weak or incapable, flowering trees that grow towards the center. One-year shoots shorten to 3-5 buds, of which new processes with large buds will appear already this year.
Once every 5-7 years old, rejuvenating pruning of a hydrangea should be carried out: in early spring all shoots over five years old are pruned at a height of 10 cm from the ground. However, the rejuvenation of very old plants stretch for three years, otherwise they may die.
Pests and diseases of hydrangea tree.
Tree hydrangea can damage spider mites and green leaf aphid - sucking insects that feed on the sap of leaves and young shoots of a plant. It makes no sense to waste time trying to destroy the pests of hydrangea folk remedies, it is better to immediately begin processing the shrub with a solution of acaricide. Copes well with sucking pests Aktellik, Fitoverm, Aktara, Sunmite.
Because of diseases, hydrangea trees may suffer from powdery mildew, downy mildew (resuspension) and chlorosis. Fungal diseases are treated with fungicides. For example, when a whitey powdery mildew appears on the leaves, hydrangea should be treated as soon as possible with a solution of Bileton, Quadrice, Topaz, Fundazole or another drug of similar action. From perinosporosis, the plant is treated with biofungicides Hamair, Alirin-B or Fitosporin. Solutions are prepared in accordance with the manufacturer's instructions for the chemical preparation, strictly observing the dosage and the interval between treatments.
As for chlorosis, which is manifested by discolored spots on the leaves, it usually arises from an excess of humus in the soil or a lack of iron in it.
Reproduction of hydrangea tree-like division of the bush.
It is possible to divide a hydrangea tree bush both in spring and in autumn: a bush is dug out and taken to pieces so that each delenka must have renewed buds. Parts of the bush are planted in pre-prepared pits. If you spend the procedure in the spring, by the fall of the bush will already take root in new places.
The reproduction of hydrangea tree layering.
This is also a fairly easy to perform breeding method, which gives good results. In the spring of one-year shoots bend to the ground, laid in the pre-made grooves up to 10 cm in depth so that the apical area with a length of about 20 cm remained above the surface. Layers fixed in this position, and the groove is thrown fertile soil. The entire season of the layers is watered and fed together with the mother plant, and in the fall or next spring it is separated from the bush and planted in a new place.
Reproduction of hydrangea tree spring and summer cuttings.
This method of reproduction of hydrangea tree is used most often. Spring cuttings are cut in early June in such a way that they have a heel in their base - a small part of last year's escape. Summer cuttings are harvested in July from the apical, non-lignified part of the shoot. On the cuttings should be 1-2 internodes. The upper leaves are shortened by half, the lower ones are removed. For successful rooting in conditions of high air humidity, a fog producing installation is required, and a soil mixture of two parts of peat and one part of sand is used as a substrate, although cuttings can also be rooted in leafy ground covered with a 3-4 cm thick layer of sand. at an angle of 45º, on top of the greenhouse covered with a transparent cap. Rooted cuttings spend the first winter in a cold greenhouse or basement, and in spring they are planted in the ground. Next winter, the cuttings are well covered with lapnik branches, and in a year they can already winter without shelter.
Varieties of hydrangea tree
Not many varieties of tree hydrangea are cultivated in garden plots. The best of them are:
- – hydrangea tree Grandiflora - shrub 1.5-2 m high with a crown with a diameter of up to 3 m. The leaves of the plant are light green, up to 16 cm long. Cream-white flowers with a diameter of up to 2 cm are collected in corymbose inflorescences up to 20 cm in diameter. Abundant bloom lasts from June to September

Hydrangea tree in landscape design
Tree hydrangea looks great in both single and group plantings. It is surprisingly in harmony with clematis, lilies and roses. Use the plant to create trees and shrubs compositions in combination with coniferous plants, as well as a hedge, does not require formative pruning. No matter how you decide to use a hydrangea tree, it will no doubt decorate your site.
With choosing a place for the plant should take into account a few points. First of all, you should not place a tree hydrangea next to woody plants, as it will feel a lack of moisture.
Hydrangea tree will feel most comfortable in partial shade. Being in a too sunny place is only possible if there is excessive moisture. The best option - a shaded place, which penetrates the sun only in the morning and evening. Best suited windows western or eastern parties.
Compliance with the temperature regime is very important for the healthy growth of hydrangeas. It is necessary to prevent the hydrangea from being at very low or high temperatures, as this can lead to negative consequences. The optimum winter temperature is 4-9 ° Cat other times - not higher20 ° C.
For the growth of hydrangeas need the right soil. It should be:
- Enriched with peat, humus or mineral fertilizers,
- Well rammed
- Have good drainage.
- Ready soil can be purchased in specialized stores. Suitable universal. It can be enriched with the necessary substances at home.
How to care?
For hydrangea needed abundant watering. It quickly evaporates moisture and with its lack begins to fade. Especially the plant needs watering from spring to autumn. It is recommended to water the plant at this time. 1-2 times a week. Intensive watering in winter hydrangea tree can cause rotting of the roots. Soft rain water or room temperature tap water is best for this procedure.
A timely intake of nutrients is the key to a good growth of hydrangea. The plant should be fertilized. every two weeks mixtures of mineral fertilizers that can be purchased at a specialty store. Once a month make feeding with a solution of potassium permanganate, which strengthens the plant. These procedures must be performed before it blooms.
If the acid-base balance of the soil is disturbed, top dressing will help restore it. For this plant once every two weeks It should be watered with a solution of sulphate of iron, which must be taken in a proportion of 2 g per liter of water. 2-3 sessions This procedure will help to cope with the problem.
Due to the fast tempo of hydrangea speed, pruning should be done Every year. It is produced in the spring and autumn periods.
Crop young hydrangeas can be dangerously, since there is an increased movement of the juices, and damage to the structure of the plant can lead to its death.
Trimming is carried out in 4 stages:
- Inspection of the bush for damage, broken branches. Removing defects.
- Removal of old shoots. It speeds up the metabolism in the plant. This stage is intended for plants older than 5 years.
- Last year's processes are shortened by 6-8 buds.
- Destruction of small shoots that do not form inflorescences. They must be removed because they take away a lot of nutrients.
Preparing for the winter
In winter, hydrangea is especially vulnerable even in spite of its cold resistance. In order for the plant to safely survive the winter, you need to prepare it in advance. For this you need:
- Manually remove fallen leaves.
- Sprinkle with the base of the bush,
- Arrange the planks around the plant and fasten the plant stems on them with ropes,
- Cover with cellophane.
So she will survive even the coldest winter.
Flowering begins at 4 years of age. It is distinguished by its duration. Usually lasts 4 months - from July to October.
Inflorescences are located at the ends of the stems and have a spherical shape. Hydrangea flowers are usually white, blue or pink, but there are other variations of paint. Color depends on the acidity of the soil. Blue flowers grow in acidic soil, and flowers painted in warm colors in alkaline soil.
Good pruning helps speed up flowering and increase its intensity.
To successfully produce reproduction by cuttings, they must be prepared in the middle of summer. It is best to do this in the morning when the plant is sufficiently saturated with moisture.
Not lignified shoots with 2-3 internodes will serve as good cuttings. To avoid further evaporation of moisture, the leaves are cut in half by cuttings. The handle should be placed at a depth of 2-3 centimeters in a container containing a substrate of peat and sand in a ratio of 2: 1. Between cuttings should be kept a distance of ten centimeters, as the hydrangea roots grow horizontally. The cuttings should root at a temperature of 19-20 ° C.
A month later, the cuttings can be transferred to the ground.
Reproduction cuttings in the fall fraught with difficulty. Problems may be caused by the need to preserve young shoots in winter conditions. For this purpose, the substrate prepared for cuttings is enriched in advance with a solution against the formation of rot. This will help avoid some of the problems with watering.
After the cuttings are planted, the container with them is wrapped in a bag of polyethylene, forming a kind of greenhouse. It should stand in a bright place and air several times a week. As the shoots grow, you can increase their time in the open air.
Reproduction by dividing the bush considered the easiest. To do this, you need to dig a plant and cut it in half together with the shoots and root system. The resulting bushes to plant in a new place.
The division should be done before the start of the flow of the plant.
Reproduction by layering not difficult even for a beginner. It is performed in spring. For successful reproduction you need to follow the step-by-step instruction:
- To prepare in the ground a groove about ten centimeters deep.
- Take one of the shoots from the plant, bend it down and put it in this groove.
- Secure it and pour 1-2 cm of soil on top.
- Bend the upper part of the shoot upward at an angle of 45 °.
- Regularly water, weed and loosen. During the season, add soil 3 times more.
- The next spring is separated using a secateur from a large bush. With a lump of land to plant in a new place.
Hydrangea, obtained in this way, begins to bloom for 4-5 years.
Diseases and pests
Hydrangea is prone to many diseases. They can occur if the conditions for the healthy growth of the plant have been violated.
- Trachemicomy wilt
This disease is caused by soil fungi pathogens. The first sign of damage to the plant - the roots rot and turn brown. The flow of nutrient supply decreases, and the upper shoots begin to wither. In this case, saving a flower is almost impossible, so the best way out is to carry out preventive measures.
Fungal plant disease. First of all, it affects young shoots with a light gray rash. With the development of the disease, it affects the hydrangea completely. High humidity has a positive effect on the development of the disease. To cure the disease, you need to remove the infected parts of the plant, then disinfect the container in which the hydrangea grows. For prophylaxis, treat the plant with Fundazole.
Fungal disease. Often, pathogens live right in the soil. White patches appear on the affected areas. Later the leaves begin to wither, the tops of the shoots dry out. With a strong defeat of the plant does not bloom. To cure a plant, it is necessary to remove its infected parts, then observe a favorable temperature and light conditions, as well as fertilize it properly. In case of severe injury, use Vitaros or Fundazol.
Activity pests can greatly harm the hydrangea, if not in time to take the necessary measures.
Vs aphids, spider mites and other parasites effective remedy fitoderm. If the insects are not very many, they can be removed mechanically.
A special kind of pest – snails. They are found in gardens and open areas. They penetrate the soil and with the onset of spring eat the roots of the plant. Usually eggs are laid there. To prevent snails, you should periodically check the ground around the bushes for their presence and remove them. In cases where there are too many snails, you can use chemicals that are sold in specialized stores.
Features of the plant
Rounded shrub formed thinish shoots, which are covered with a small amount of fluff. Egg-shaped leaves about 20 cm long are painted in a bright green shade. Their lower surface has a light green-bluish color. The leaves are attached to the branches with the help of long and thin petioles. They are located on the shoots opposite each other (the so-called opposite arrangement).
Quite large inflorescences with a diameter of almost 15 cm, which are shaped like a scutum, are formed from whitish flowers about 2 cm wide. The lush bloom lasts from mid-July until October. Seeds ripen in October.
This type of hydrangea is different:
- good enough winter hardiness
- that actively grows after winters with severe frosts,
- high percentage rooting cuttings.
Tree hydrangea is best developed on soils with a weakly acid reaction (pH at a level of 5.0), but is more tolerant to the presence of lime in the ground than other types of hydrangeas.
Based on this species, several varieties have been created that can be purchased in the nurseries of our country:
The well-known and very popular Annabelle variety (Annabelle) attracts attention with large and heavy snow-white inflorescences up to 25 cm wide, which can lodge. This is quite unpretentious and fast-growing plant reaches a height of 1.0 to 1.5 meters and a width of almost 3 meters. Flowering lasts all summer (three months).
Shrubs "Grandiflora" ("Grandiflora") like for a spectacular view and long-lasting powerful flowering. Lush blossoms during flowering change color several times. When blooming inflorescences are painted in a delicate greenish tint, then they become white. By the end of flowering inflorescences take a light whitish-cream color. The height of the bush is about 2 meters, and the width can reach almost 3 meters.
The variety "Invincibelle" ("Invincibelle") or "Pink Annabelle" ("Pink Annabelle") was created on the basis of "Annabel". This first tree hydrangea, painted in pink. In addition to color, it is interesting because if after the first flowering the bush is cut, the plant will bloom again after 6 weeks. At the International Exhibition of Nursery Products "Plantarium 2011" this variety received a bronze medal.
"Strong Annabelle" ("Strong Annabelle") or "Incredibol" ("Incrediball") is also obtained using the variety "Annabel", but its white inflorescences, dissolving on strong and strong branches, do not lie down from wind and rain. Flowering lasts from June to September. This variety has an international competition award.
- The width, length and depth of the pit varies from 30 to 40 cm, depending on the size of the coma with the roots (container plants) or the root system (seedlings with ACS).
- Since tree hydrangea is demanding for the presence of moisture and nutrients, it is advisable to fill the holes during planting with a mixture of river sand, leaf humus, compost or sod land.
- When the plant is planted, the root neck (the place where the branches end and the roots begin) is placed at ground level and ensures that it does not turn out to be covered with earth.
- Roots before planting check and cut the broken, strongly dried and unnecessarily long. The bulk of the roots should be approximately the same length. If container plants are planted, tangled roots are also straightened and slightly pruned.
- To accelerate survival, the roots are soaked in a heteroauxin solution for several hours (from 2 to 24), and then immediately planted.
- After planting, the plants are watered with plenty of water and fill up the settled soil.
Even a slight drying of the roots leads to difficulties with rooting, and also negatively affects the further growth and development of the bush.
Newly planted bushes need to be protected from strong sun and strong air currents for several weeks.
Tree Hydrangea Care
For lush flowering and good development of hydrangea required top dressing, watering, trimming and mulching.
All species of this plant need regular watering. And at a time (every week), a bush pours from 15 to 20 liters of water. If precipitation falls often, then watering is carried out once a month.
Four seasonings are usually carried out per season.
- The first is held at the time when shoots begin to grow. For it use a complete fertilizer with nitrogen, phosphorus and potassium, and the nitrogen should be slightly higher than other elements. It is advisable to add some trace elements to this fertilizer.
- The second time the bushes feed up when buds begin to form. To do this, take potassium sulfate and superphosphate.
- The following two additional feeding are carried out using the same fertilizer during the summer.
Mulching and loosening
Mulching of the soil around the bushes is an important measure for the maintenance of tree arthritis. It is carried out after the shoots begin to be advanced. The height of the peat layer, sawdust or wood chips is from 5 to 8 cm. But you need to make sure that the layer of mulch does not come into contact with the trunks and shoots, and was moved away from them by a few centimeters.
With such agrotechnical reception, the area around the plant should be loosened only 2 or 3 times for the whole season to a depth of 5-6 cm (excluding the mulch layer).
Reproduction by cuttings
It is quite simple and easy to propagate tree hydrangea using green cuttings, the percentage of rooting which reaches 100 percent (when processed with a solution of indolylbutyric acid).
Cuttings harvested in two terms:
- the first time it happens in early June, but at the same time in its lower part there must be a piece of the last year’s escape,
- the second time the cuttings are cut in July, but you need to do this before the moment of complete lignification of the shoot. To do this, choose the branches that appeared this year.
- Cuttings are cut with 2-3 pairs of leaves, leaf plates cut by half.
- The sections are treated with a root growth stimulator and the cuttings are planted on a shady bed with moist, loose and nutritious soil or in greenhouses. The lower pair of buds is buried in the ground until the middle of the internode.
- The whole rooting process lasts from 20 to 30 days, but all this time it is required to maintain a high level of humidity. To do this, they are covered with cut plastic bottles.
Reproduction by layering
Also, hydrangea tree multiply layers. To do this, in spring the shoots gently bend down to the ground in a shallow and long hole, fall asleep with a layer of soil 1.5-2 cm and fix. At the same time, the end of the shoot is left free from the ground and slightly bent up.
Throughout the season, the soil is gradually poured into the hole 2-3 times and kept moist. The following year, the rooted shoots are separated from the bush with a secateur and planted on a bed in partial shade or shade to grow.
Hydrangeas grown from cuttings and layering, ready for planting in a permanent place in 1-2 years. Flowering occurs in the fourth year of life.
Tree hydrangea can be successfully propagated by dividing the bush. The shrub is dug out and divided with the help of a sharp spade, pruner, and for the division of old bushes it is often necessary to use an ax.
The resulting parts are planted in prepared pits. Then pruning is done. They take root, as a rule, well.
Pruning and further care is carried out in the same way as for transplanting hydrangeas (see below).
Hydrangea tree blooms on shoots that have appeared this year. Over time, the bushes quickly thicken, resulting in lower flowering quality.
Regular heavy pruning, which is carried out in early spring (March-April) allows you to keep the bushes in good condition. As a result, strong and strong shoots appear on which large inflorescences bloom in summer or early autumn.
Strong shoots are shortened by 3-5 buds, weak ones - by 2-3 buds, so that the upper buds “look” outside. Тогда кустарник будет более пышным, а середина кроны не загущенной.
После обрезки растения обязательно подкармливают полным удобрением с азотом, фосфором и калием.
For the rejuvenation of adult bushes is very strong pruning. During it, all branches are cut at half a meter from the surface of the earth. After such pruning plants bloom only after a year.
Not subject to trim young, not yet flowering specimens, under the age of 4 years.
Hydrangea transplantation is best done in early spring, immediately after the snow melted. In the southern regions it can be done in the fall.
Replant the plant with a large lump of earth, trying to preserve it as much as possible and not damage the roots. After transplanting shrubs watered.
Before or after transplantation, pruning of a hydrangea is performed; it is more convenient to do it first. At the same time, the shoots are shortened by one third of the length according to the rules of forming trimming.
If when digging out a bush the root system is damaged or the earthen room has collapsed, pruning is carried out more radically, otherwise the plant may not settle down.
In the next 2-3 weeks, the transplanted hydrangea should be slightly shaded from the bright sun.
It is important to remember about regular watering in hot and dry weather.
Fertilizing the plant can be done no earlier than 3-4 weeks after transplantation, when the growth of shoots will resume, which is a sign that rooting has happened successfully.
Popular tree hydrangea varieties
- Hortensia Annabel - in height the bush reaches 1-1.5 m, and in diameter - up to 3 m. The inflorescences of this tree hydrangea are large, the flowers are white. Evergreen shrub, leaves do not turn yellow in autumn,
- Hortensia Pink Pinkushen - low shrub (only up to 1.2 m in height), up to 1.5 m wide. Can be planted both in sunny areas and in partial shade. Blooms pinkish white flowers
- Hydrangea Treelike Grandiflora - blooms with cream flowers, inflorescences are numerous. Not to be confused with the look of hydrangea grandiflora,
- Hortensia Sterilis - inflorescences are large, with white-green flowers, which eventually become completely white. It blooms long and plentifully.
Watering Tree Hydrangea
Tree hydrangea is a very moisture-loving plant, so in the summer it is watered at least once a week, pouring 1-2 buckets of water under each bush. Water for irrigation is better to use rainwater, collecting it in tanks and letting it settle. If the plot is not mulched, then the soil needs to be loosened and weeded away from weeds. In order for the earth to keep moisture as long as possible, the near-stem circles of plants can be mulched with sawdust or peat.
Planting tree hydrangea in open ground
When to transplant a hydrangea tree? Hydrangea bushes are transplanted in spring, in early March, but they must first be prepared (at the end of autumn) for transplantation. To hydrangea easier to endure this procedure, you need to dig a small trench around the bush and fill it with compost. To better compost the plant, the trench should be regularly filled with water.
Pruning of hydrangea in autumn after flowering
Top dressing tree hydrangea
For full development, active growth and abundant flowering tree hydrangea must be fertilized. How to feed the hydrangea? The first dressing is carried out in the spring at the beginning of the growing season - it is best to make ready-made fertilizers like “Kemira-flower”. The next time the plant will need to feed during the formation of buds, for which make 25-30 g of potassium and 50 g of phosphorus. Fertilizers can be applied to the soil and dairy products (in small quantities and diluted with water). To reduce the likelihood of fungal diseases and strengthen the shoots, you can water the bush with a weak solution of potassium permanganate.
Reproduction of hydrangea apical layers
The easiest way and with the least harm to the plant is the reproduction of tree hydrangea layers. All that is needed for this is to bend the shoots of the hydrangea to the ground, fix it with a pin and sprinkle with soil. From the ground, the shoot should stick out at an angle of 45 º. For rooting, you need to periodically water this place and pour the soil. It will be possible to separate the rooted cutting from the mother plant and plant it in a permanent place next spring. The young bush will bloom for 4-5 years.
The reasons why the tree hydrangea does not bloom:
- young age - hydrangeas begin to bloom only at 4-5 years of age,
- freezing of shoots
- improper care of hydrangea in the garden (insufficient watering, lack of fertilizer and too much pruning).
Despite the fact that hydrangea requires attention and certain actions, it is becoming more and more popular every year with gardeners. And all because of its incredibly beautiful and numerous buds that adorn the garden from June to September. Well, do not forget about the frost resistance of tree hydrangea, which is another advantage.
Hydrangea tree grows up to one and a half meters in height and belongs to deciduous shrubs. It has tubular shoots, the leaves are large and green, covered with a grayish pubescence from below. It blooms from July to October. Differs in resistance to frosts and fast growth.
Hydrangea tree has become the basis of many cold-resistant varieties that have different flowering periods, shades of inflorescences and their sizes. The most popular of them are:
- Anabel - The height of the plant is one and a half meters, the width of the crown is at least three meters. This variety blooms from July to September with dense spherical inflorescences. The leaves fall in autumn, but do not change color,
- Pink Anabel - selection deduced variety of pale pink color,
- Strong Anabelwhich is also bred selectively. This type of plant has strong stems that are capable of holding spherical inflorescences without a special garter,
- Sterilis - differs in plentiful flowering, but at the same time does not give shoots. In height reaches no more than two meters. Initially, flowers have a light greenish tint, which eventually changes to pure white. Plant blooms from July to October
- Hayes Starburst - has large terry inflorescences of snow-white color,
- Pink Percussion - has small inflorescences, which are located throughout the bush.
Hydrangea Transplant Rules
In order for the tree hydrangea to bloom and for a long time to please you with its flowering, you should take into account the rules of its transplantation and reproduction. In particular, it concerns the choice of soil and proper lighting.
Replant the plant is often not worth it. It is extremely sensitive to transplants and is sick for a long time after that. Therefore, you should initially correctly select the place where it will grow for a long time without transplants.
In general, tree hydrangea grows well in any light, but the breeders found out a little more:
- in bright sunlight plant growth slows down significantly and inflorescences are greatly reduced,
- too thick shadow leads to the fact that the inflorescences do not develop and the plant blooms less often.
The best option for the perfect growth of hydrangea will be partial shade. To do this, you should choose a site on which the midday shade and the morning and evening sun will be present.
In general, the composition of the soil hydrangea unpretentious. But preference gives light loamy soils with acid content. Like all plants of its genus, tree hydrangea requires the presence of fungi in the soil. It is this type of hydrangea that best tolerates the presence of lime in the soil.
Soil should pick up a light, breathable and moisture in sufficient quantities. But adding sand to the ground, it should be noted that the water will very quickly go deep. And if the soil lacks acidity, it can be easily increased by making sawdust or special fertilizers.
The acidity of the soil significantly affects the brightness of the color of the buds. It is enough just to water the plant twice with a bucket of aluminum sulphate solution and bright white inflorescences will turn blue, and the pink flowers will turn purple.
Optimum landing time
The flower can be planted in the fall and spring. Each season has its own significant advantages. So, the hydrangea planted in autumn will bloom in the spring. But for the autumn planting should choose a full-fledged bushes with a developed root system. In the northern areas, planting should be carried out at the end of September, and the plant should be carefully wrapped up for the winter.
Spring planting has a number of advantages - it quickly takes root, it hurts less and winters better. It should be remembered that if the plant is bought in the store and its root system is covered, then it can be planted at any time from spring to autumn.
The right choice of seedlings
In the store you can find seedlings with open and closed root system, located in special containers. When choosing them, you should pay attention to the following characteristics:
- plant height - not less than 50 cm
- on the shootswhich must be at least 3 pieces
- on the kidneysthat should be alive and large,
- on the quality of the barkwhich must be intact.
If the plant is sold with open roots, then they must be developed, without rot and dryness. The length of the roots should not be less than 30 cm. If the root system is hidden in a container and is not subject to inspection, you should consult the seller when the seedling has been transplanted. The recent planting is highly undesirable, because the plant does not take root.
Right before landing, you should carefully examine the earthen room. It should be located young white roots. It is recommended to plant three - four-year plants. It is recommended to purchase seedlings with open roots immediately before planting. If there is no possibility to do this, then the seedling should be put in a dark place for a while and moisten its roots.
Hydrangea Tree Planting and Care
Hydrangea tree unpretentious. Caring for her comes down to watering, fertilizing and mulching the soil. True, it is recommended to trim it a little once a year.
Watering plants is extremely important, because its scientific name translates as "hydrangia" and directly indicates how much it loves water. The hydrangea root system is shallow and grows wide. Therefore, if the moisture is deep or turned out to be a dry period, the plant will wither greatly and its flowers will become less saturated.
Each hydrangea bush should receive at least 30 liters of water weekly. But if you carry out the correct mulching and it rains regularly, then watering should be slightly reduced. Watering the plant can only be soft water, so it should be prepared in advance. Water should be poured into a bucket and allowed to stand.
Watering is recommended in the morning or evening with water at room temperature. In this case, the water should not fall on the inflorescences, so as not to break them and they did not begin to rot.
The first year after planting fertilizer is not required. It will be enough that it was put in the hole when landing. Next, you need to make fertilizer at least three times a year. The first time feeding is made when the first shoots appear, the second - when the buds appear, and the third - during flowering.
All types of fertilizers should be applied before September, because at this time the plant is already beginning to prepare for sleep. And there will be no benefit from dressing.
Plant trimming rules
Hydrangea treelike incredibol requires regular pruning. This is part of the basic rules for caring for your favorite plant species - grandiflor or any other species. According to the practice, it is quite simple to trim a plant; you just need to start doing it regularly and do it regularly. The first pruning is done in the first year after planting.
This procedure of care is extremely important in that it helps the plant to multiply actively and increase the number of inflorescences and shoots. The main time for pruning is early spring, when the snow has already dropped, and the leaves on the shrub have not yet appeared.
In the spring, the following types of pruning:
- sanitary, in which old, dried and broken shoots are removed,
- rejuvenating, in which all old shoots are removed at the root,
- thinningin which weak shrubs are completely removed so that stronger neighbors can grow and develop.
In the autumn, only shortening pruning is allowed, which will help ensure proper care of the plant during the winter period.
Plant propagation rules
Most often, hydrangea grandiflor or another species breeds in several ways. The least used of these is seed dilution. In this case, the hybrid properties of the flower cannot be preserved and seed germination is quite long. And the first flowers on the plant will be with the best scenario, in five years.
The most common method is breeding cuttings. The cuttings are used for this stiff and green. In the first case, the shoots taken in early April. From cut shoots make two cuttings with two buds. Plant such cuttings into the soil at an angle of 60 degrees. Then it is covered with film and placed in the greenhouse.
In the second case, grafting occurs in summer or autumn. Cuttings are cut with two leaf buds. In this case, the lower leaves should be removed, and the rest simply shorten by half.
The shank is required to process for at least half an hour in a solution of Fundazole and treat with a means of accelerating the growth of roots. After that, the stalk is planted in soil consisting of sand and peat. Cover the stalk with a can and leave until full rooting. The rearing of such a plant occurs in the spring, after planting hydrangeas in open ground.
Reproduction by layering is used if the territory of the garden allows you to perform this procedure. To do this, carefully dig the soil around the bush and level it. Select the bottommost shoot and remove most of the leaves from it. Make a hole in the dug soil no more than 10 cm long. Escape to fix the hole in the hole with specks and sprinkle with soil. After that, you need to carry out the standard care of hydrangea grandiflor or other species.
By dividing the bush to multiply the plant is extremely dangerous. Especially if you are a novice gardener. Before performing the procedure, you need to prune the outer shoots and carefully water the soil around the bush. After digging up the roots need to be washed. After that, the bush is divided into several parts and the ends of the roots are trimmed. Each bush is planted in a separate, carefully prepared place.
Wintering hydrangeas and parasites
Despite the fact that the tree hydrangea has excellent frost resistance, there is still no risk. It is better to cover it for the winter as carefully as possible. First you need to spud the bush and add mulch and peat to it. All shoots need to be carefully tied. Bending them to the ground is not worth it - you can easily break. Around the bushes should drive a few pegs and wrap them agroteksom. After that, it will be enough to tie a bush with string and that's it, the plant is ready for wintering.
It should be remembered that if properly care for hydrangea, then it rarely gets sick and it never affects pests. But if it gets too much moisture or there is a big temperature drop, then it can get powdery mildew and gray mold. First of all, leaves and flowers are affected. But to cope with this is very simple - it is enough to process the plant with Bordeaux mixture or Chistotsvetom.
Of the pests most often the plant is affected by snails and spider mites. The first should be regularly robbed so that they do not eat flowers, and the second can be destroyed with the help of insecticides - Inta-Vir, Fitoverm.
Growing hydrangea in your own area is quite simple, if you follow all the rules of care and reproduction. Therefore, you should heed the advice of experts and enjoy the beautiful flowering of a luxurious bud in your garden.
