Hydrangea - a popular garden plant, characterized by unpretentiousness and simple care. It is widely used for decorating plots, gardens and urban landscaping. This is an artisanal, liana or tree plant, reaching a height of 1 to 5 meters.
There are a large number of varieties of hydrangea, differing not only in external features, but also in the rules of care. In mid-latitude conditions, the flower is grown as a perennial. In the article we will look at how to care for the hydrangea in the spring, since it is this issue that causes the greatest difficulties for florists.
Types of hydrangeas
As an ornamental plant, more than 80 types of hydrangea are actively used, within which about 5 thousand varieties have been bred. They are very different external characteristics. Depending on the variety, it can be a vine, a tree-shrub, or a grassy plant. This leads to a significant difference in care, the specific content and dilution. The most common types of hydrangeas:
- Tree. In the wild form is found in North America. This is a large plant, whose height reaches 3 meters. Inflorescences are usually spherical, painted white or cream color. Flowering continues from June to September
- Large leaf. The homeland of this species is Japan and China. Actively used for landscaping gardens and plots. It is used in landscape design most often, because of volumetric flowers it is often called large-flowered. Some varieties are able to grow up to 4 meters in height, gathered in corymbose inflorescences, differing in shape and color of petals,
- Paniculata. In the natural environment, it can be found in Japan, China and the eastern regions of Russia. Depending on the variety, it is a shrub or tree up to 10 m high. It is valued for a thick and very decorative leaf crown. The flowers are large, the petals are first painted white, and then gradually turn pink.
In addition, in the landscape design for landscaping use hydrangea. oak-leaf, petiole and serrate. These are more capricious varieties of plants, so they are less popular.
Features care for hydrangea after winter
Work with hydrangea begins after the snow completely disappears in spring - from the end of March to the beginning of May, depending on the growing region. To provide the plant with all the necessary elements at the start of the active growing season in the fall, organic fertilizer or phosphorus-potassium chemical fertilizer should be applied to the soil.
After the snow melts, you can remove the winter shelter to provide access to the air. Spring care is reduced to simple, but important procedures - working with the soil, applying fertilizer, competent watering and planned pruning. If necessary, it is at this time convenient to transplant plants to a new place.
Watering Hydrangeas in the Spring
Regardless of the variety of hydrangea after winter dormancy, a large amount of moisture is required to begin the development and formation of flowers. This is a moisture-loving plant, so the soil should be sufficiently moist. On average, it is recommended to use 10-15 liters of warm water on a bush.
To prevent infection during irrigation, it is recommended to add some potassium permanganate. Watering is carried out in the morning. Water should be poured exclusively under the root, avoiding moisture on the stems and leaves. The optimal irrigation regime is 10-15 liters of water every 7 days, in dry regions it is permissible to carry out the procedure more often.
If during planting you have brought in a sufficient amount of organic matter, you do not spend top dressing for the first two years - the plant has enough nutrients and macronutrients from the soil during this period. Then feeding is carried out three times per season.
After the formation of the first green parts to mid-May, you can apply fertilizer. For this purpose, apply complex compositions at the rate of 25-30 g per 10 liters of water. If you are preparing a top dressing yourself, then you should mix 15 g of urea, 30 g of superphosphate and 15 g of potassium sulfate per 10 liters of water. The procedure is recommended after irrigation, so that water does not wash away the nutrients.
Garden hydrangea responds well to organic compounds, so it is advisable to use a solution of mullein or bird droppings in a ratio of 1:10. It is especially important to introduce organic matter when growing plants in poor soils, as well as for paniculate and large-leaved hydrangea. Subsequent feeding is carried out in the stage of active flowering plants in mid-summer.
In order to avoid drying out of the soil, as well as to ensure a comfortable aeration of the root system in the spring, the soil is loosened and mulched. For this area pristvolnogo circle cleaned from the remnants of foliage, weeds. After that, with the help of a special chopper for flowers, they carefully loosen the ground, but one should not go deep into the soil so as not to damage the roots and the stem.
At the same time, mulching of the area where hydrangea is grown is carried out. The procedure should be carried out regardless of the type of plant. Peat chips, wood chips or bark are best for mulch. It is placed in a uniform layer up to 10 cm thick. The mulching carried out will not only keep the substrate moisture, but also reduce the number of weeds in the plot. In addition, mulch, falling into the ground, enriches it with minerals, corrects the level of acidity.
Masking, pinching spring pruning
To maintain the decorativeness of the plant should be regularly cut. The procedure is preferably carried out in early spring before the formation of a large number of young shoots. It is carried out, starting 3-4 years of plant growth. For different types of pruning is different. As a rule, apply decorative or sanitary pruning. Every 3-5 years, the plant needs rejuvenation, regardless of its type and variety.
Pruning of large leaf, serrate and barbed hydrangea
These species differ in that flowering occurs only on last year's shoots that need sanitary and decorative pruning. The optimal time of the procedure is the period of swelling of the kidneys when there is no active excretion of juice. Cropped shoots can then be used as planting material.
In this case, very young shoots are pruned, and also remnants of the last flowering and branches growing inside are removed. The procedure is decorative, so you need to carefully examine the ovary, which can not be damaged. The exception is large leaf hydrangea, which cannot be cut, but it is important to rejuvenate. A sterile and sharp instrument should be used; it is recommended that the cut points be treated with activated charcoal crushed to powder.
Trimming Tree and Paniculata Hydrangeas
These are large plants that also require spring shrub forming. They bloom on young shoots, so the old parts of the hydrangea need to be cut off in time to feed the new parts of the flower. The recommended procedure time is mid-March after the snow melts.
Tree hydrangea is pruned to 2-3 buds from the ground on each shoot, on the old plant you can leave only a few ovaries, which are sure to form inflorescences. During shaping, it is also necessary to remove the weak and growing inside parts of the plant. The paniculate variety of the flower needs less shaping, so in this case, only last year's shoots are cut to 1/3 of their length.
Transplant in spring
It is desirable to replant the plant only in the spring before the buds begin to swell. This is important for maintaining the health of the root system, since growing a flower in one place for more than 5-7 years increases the risk of developing dangerous diseases. To facilitate the transplantation procedure, experienced gardeners recommend cutting the bush as much as possible in the fall, leaving only a few strong and healthy stems. Transplant Algorithm:
- It is advisable to prepare the pit for the plant in a new place in the autumn. The recommended size of the planting hole is 50x50x50 cm. Hydrangea grows quickly, so the distance between the plants should be at least 1.5 m.
- It should be laid a layer of organic fertilizer, or feed the soil complex composition.
- The plant is carefully dug together with a lump of earth, and then transferred to a new location.
- It is impossible to damage a weak root system, position it in such a way that the root collar is at the level of the upper layer of the soil. Then the landing hole is completely filled with the substrate, and mulching is carried out.
After transplantation, the plant needs to be plentifully watered, the first top dressing is brought in only 14-20 days, but if you prepare the ground with high quality in the fall, fertilizer should not be applied in the first year after transplantation. When grown in the northern regions of Russia (Siberia, the Urals and North of Karelia), after transplantation, it is desirable to cover young plants before the onset of stable sunny weather.
Hydrangea is characterized by strong immunity and resistance to most diseases. In order to prevent, regardless of the type of plant, it is desirable to carry out planned treatment in the spring. As a tool, it is recommended to use insecticides of a wide spectrum of action, for example, Actellic, Confidor and Aktar. Every year, be sure to handle planting fungicides. Copper sulphate or Bordeaux liquid is best suited for this purpose.
Before processing, you should carefully read the instructions for use, dosage and method of application. The procedure is preferably carried out after irrigation in dry and clear weather. During processing, you should remember about the precautionary measures, since most of the compounds are toxic to humans.
Diseases and pests
Among the pests, aphids, mites and stem nematodes are the most dangerous. They affect the vegetative parts of the plant, reduce the rate of development and can lead to the death of the bush. If there are signs of disease (appearance of characteristic spots, colonies of insects and wilting of the leaves), it is necessary to treat the planting with an insecticide or use traditional methods - spraying with soapy water, dusting with tree ash.
Infection with diseases occurs much more frequently. As a rule, diseases develop when growing hydrangeas in poor soil, non-compliance with the rules of care. The most frequent diseases of this culture:
- Chlorosis. Leaves become discolored, brown spots appear on leaf plates and stem. The plant slowly fades, may die,
- Gray rot. On the shoots appear brown spots, which are covered with gray bloom. The disease responds well to treatment Bordeaux liquid, most often the flower can be saved,
- Mealy dew. The leaves begin to turn yellow and curl, many yellow spots appear on them. As a rule, the disease occurs when landing in conditions of high humidity.
The choice of fungicides against the disease depends on its type, symptoms of infection. When carrying out routine preventive treatment each year, the risk of developing diseases is significantly reduced.
Caring for hydrangea in the spring is an important part of the maintenance and breeding of these universal decorative flowers. To enhance the quality of flowering, maintain health and stimulate growth, it is necessary to timely trim, loosen and mulch the soil. Starting in spring, regular watering is an essential part of care, and you also need to add fertilizing on time.
Pruning hydrangeas has several goals. Without it, the plant can naturally grow, but this leads to shredding the inflorescences and reducing their number. Also, a well-formed bush looks more decorative, which adds beauty to the garden. Thanks to pruning, the following goals are achieved:
- beautiful bush form with an abundance of green mass,
- plant rejuvenation
- maintaining health
- bloom improvement.
The procedure annually gives impetus to the abundant growth of young shoots, which quickly pick up flowers. Because of their shorter length, they create an abundant green mass in the lower part of the plant, where the old rods can no longer give such greens.
General rules for pruning
Hydrangea must be trimmed correctly, because otherwise it can even be ruined. There are general guidelines that apply to all varieties and species. You can not cut the plant with rainy and very dry weather, as well as with strong heat. It is better to carry out pruning in the evening, then all the damaged places will have time to drag on in the morning and will not attract unnecessary insects and will not dry out if the sun burns much.
When pruning thick shoots that begin to liberate the juice, they are covered with garden pitch or paint so that the hydrangea does not weaken.
Usually, this phenomenon is observed when pruning a tree variety, if necessary, remove most of the crown.
The cut is made obliquely, in one compression of the secateurs, without thrashing the plant tissue. Sometimes in places where it is impossible to get close with garden shears, you can use a sharp knife or a garden file (if the branch is thick). This should be done only as a last resort, since such a trauma of the plant heals longer.
Large leaf and ground cover
Pruning of large-leaved hydrangea is carried out mainly for sanitary purposes. During it, dead shoots and already withered inflorescences are cut from the plant. You can also thin the bush a little if it is excessively thick. It is impossible to save the plant from last year's shoots before winter, since it is on them that buds for inflorescences are laid in the fall. Cutting them, the owner in the spring will receive only a lush, but not flowering shrub.
In order not to spoil the next year's hydrangea, it is necessary to cut off the flowering inflorescences even in summer. This will allow the plant to have time to give young shoots before the onset of the cold period, and, therefore, they will appear in the summer flowering caps.
When the hydrangea is sheltered for the winter, weak shoots are cut from the bush, this will facilitate its wintering.
It is necessary to rejuvenate a plant 1 time in 3 years, cutting up escapes on 30-40 centimeters. Only ¼ of all branches of the bush are affected by such a haircut.
A ground cover hydrangea also does not require a serious haircut, despite the fact that it gives flowers on spring shoots. When to trim the hydrangea - in spring or autumn - depends on weather conditions and gardener's preferences. A ground cover bush is enough to trim once a year, removing only unnecessarily long shoots that disrupt its shape.
According to the rules pruning paniculate hydrangea is held in the fall. Touch skeletal shoots can not. Pruned only those branches that grow inside the bush, excessively thickening it. Dried panicles must also be removed. Young shoots are very fragile and easily break under the snow mass. If you can see that they will not turn wood before winter, you should remove them with shears.
Before winter, shoots on which were inflorescences are cut, leaving only 2-3 buds on them. It is necessary for the spring to hydrangea, spreading the leaves, looked elegant. Buds are laid only on spring shoots.
Hydrangea paniculata, pruning which is carried out in rejuvenating purposes, is processed in the fall. To do this, cut several skeletal branches, leaving only 2-3 to grow outwards.
Pruning hydrangea paniculate spring is carried out to restore the beautiful crown after winter. From it remove the branches that have dried, unable to withstand frost, or were broken. You can also gradually create a shtamb in the spring haircuts, thanks to which the hydrangea will look like a lush floral cloud on the stem.
Pruning tree hydrangea is a must. This should be done in the fall. In winter, all dry inflorescences, if they remain on the branches, fill with snow, become overwhelmingly heavy for the plant and break it. They should be cut with a small foot. A very active haircut can harm the plant, especially if it is young and not yet ready for rejuvenation.
Serious pruning for the first time can only be carried out on plants aged 4 years.
Pruning hydrangeas in the fall for beginners may seem difficult because of the need to count the buds left on the shoots (there should be 3-4 of them), but soon it comes to automatism and problems do not arise.
Rejuvenating pruning in hydrangea trees is carried out no earlier than 7 years after planting. With a not very large root system, all shoots are cut off before winter, leaving only 10 cm of stump above the ground. If the root is strong, then only ¼ of the bush is cut off in a year and the plant gradually rejuvenates.
If the bush is completely cut off with an extensive root, it will not have enough strength to restore it. This is because the root system will need constant feeding with substances that come into it from the aboveground part, and only young runs will not be able to give them the right measure.
Pruning of hydrangeas in spring may be necessary if, after a severe winter, there are dead and broken branches on the bush. Срезают их секатором, когда уже прошел самый активный весенний сокоход, так как иначе при задевании живых тканей растение будет слабеть.
Для того чтобы точнее ориентироваться, какой вид обрезки растению нужен в конкретный момент, надо точно представлять, какой вид стрижки что предполагает.
- Rejuvenating - cutting a large number of shoots to a greater length to get new ones from the root, which will be stronger and stronger due to their young age and the absence of defects in them caused by the negative effects of the environment. Such pruning of hydrangea is carried out in the fall.
- Sanitary - removal of unsuitable shoots that spoil the appearance of the plant and create an unnecessary mass. Dry, broken and defective shoots are cut.
- Forming - the most difficult and necessary to obtain a beautiful bush. It is carried out immediately after landing and further for several years.
All pruning make shears. The use of ordinary scissors is not allowed.
It is mandatory for the first 2 years from the moment the plant was planted, and then at the request of the owner another 2-3 years. Thanks to the procedure, it is possible to lay the correct shape of the bush and provide it with strong branches that grow in a beautiful direction.
Is cutting according to the following scheme:
- Before planting - the sapling is pruned a bit so that the root does not spend a lot of effort on the aboveground part and is properly formed. Also cut off all the broken and dried shoots.
- After the winter - in March or April, depending on the climate, they make a sanitary pruning of the bush and also prune all the shoots so that the root continues to fully develop.
- In the second year - from this moment begin to form the correct beautiful crown. All shoots left over from last year are pruned, leaving 3 buds in them, which are fully developed. Extra defective shoots are removed completely. On hydrangeas, only healthy branches that grow in the right direction should remain. They are the basis of the bush and will create its shape. Conducting the formation of the crown each spring for several years in a row, you can get a particularly beautiful plant.
With proper hairstyle, the gardener gets a shrub that is notable for its luxuriant flowering and accuracy. Hortensia, which is not formed, will look disheveled, as part of its stems will have the wrong direction of growth, as well as its shape will be far from ideal.
Care after trimming
Cut hydrangea requires subsequent proper care. It consists in watering and feeding. Stimulation by pruning of the growth of young shoots occurs with increased consumption of mineral substances and organic matter by the plant, which are introduced into the soil. The organics will saturate the bird droppings, and the mineral components - ash. You can also use special complex fertilizers. Watering is carried out in wet weather 1 time per week, and in arid weather - daily.
Regularly correctly cutting off their hydrangea, the gardener receives abundant flowering and very large inflorescences annually. Without proper care, the flowers will become smaller, and the bush will not be able to please the elegance and attractiveness. In addition, it will become untidy and sprawling, which will give the garden a somewhat abandoned look.
A more vivid example of pruning hydrangea can be viewed in the following video:

Trees and paniculate hydrangeas do not require shelter for the winter, as they bloom on the shoots of the current year. However, they expect the owners to be attentive, especially during the spring pruning.
Treeline hydrangea is a typical shrub, but a pancake hydrangea grows in the form of a single-trunk or multi-stem tree and is very cold-resistant. Her one-year shoots to fall fully woody.
In the tree they do not mature enough to fall and in frosty winters can frost up to the level of snow cover. But in the spring after trimming the bush quickly recovers and blooms the same year. Because this hydrangea is cold-resistant.
If you twist the shoots of a tree hydrangea to the ground under the snow, you can grow a higher plant.
In the spring feed up plants with complex mineral fertilizer (50 g per 1 sq. m), and later with a “talker” of rotted manure. During budding give superphosphate (60 g per 1 sq. M.) And potassium sulphate (40-50 g per 1 sq. M). At the end of the season, a third mineral dressing is carried out (50 g of superphosphate and 30-35 g of potassium per 1 sq. M).
note that cut off only treelike and paniculate hydrangeas. Large-leaved and oak-leaved hydrangeas do not need this procedure! The first two types of hydrangeas can also grow without pruning, but over time the bushes thicken, lose their decorative effect, the inflorescences become smaller. They are pruned in the spring before bud break. If you cut the bush late, they will be weakened, and flowering scarce.
Have tree hydrangeas remove frozen and old shoots to the ground, to give impetus to the formation of new, as well as small, thickening crown branches. Last year's shoots are shortened, leaving several pairs of buds. The weaker the shoot, the shorter it needs to be cut.
Pruning hydrangea paniculata similar to pruning an apple tree. The trunks and skeletal branches of this species are durable, and the thicker they are, the more buds they can be left for in order to get a good growth.
In tree hydrangea old shoots are removed to the base
It is necessary to remove the branches going inward, thinning the crown: out of three shoots coming from one point, leave 1-2 directed outwards. All last year's shoots are also shortened by 1-3 buds.
Pruned hydrangeas a few years after planting.
Of panicle hydrangea can form standard form. To do this, a young bush cut out all the shoots, leaving the most powerful. It is driven out to 70-100 cm, regularly removing all lateral shoots and shoots. When the height is reached with a normal trim, a spherical crown shape is formed.
For shtambovoy formirovka hydrangea need to cut off all the shoots, except for one of the most powerful
This tree is very impressive, but requires a garter strap to a strong support.
The shoots of paniculate hydrangea are very fragile, and the inflorescences form a huge hat and can break off without a garter. In general, the breakage of shoots threatens not only stem trees, but also bushes, especially overgrown and uncircumcised.
For the winter, the inflorescences of all hydrangeas must be cut off, and the bushes must be tied. To enhance the strength of the shoots several times over the summer, hydrangeas need to be watered with a weak solution of potassium permanganate.
Why do I need pruning hydrangea
- For the correct and beautiful shape of the plant.
- That the bush looked decorative.
- To hydrangea had a healthy appearance, and its flowers were large and full.
- With the help of a professional haircut, an ordinary bush can be turned into a standard plant or give it a fancy configuration.
Terms and types of pruning hydrangea
The procedure is carried out both in spring and autumn. Moreover, in spring the exact timing of trimming hydrangeas is very important - it is carried out already when the sprigs barely show buds that show the direction in which new shoots will develop. However, they should not be allowed to “nod”. In this case, the plant can only be harmed.
In the south, as a rule, it is the beginning - the middle of March, in colder regions - the end of March and the beginning of April.
Important! Cropped later than the designated period shoots, starting to grow, begin to "cry" and literally expire juice. The plant starts to hurt and then almost does not bloom.
Autumn pruning is carried out late, because in September the plant changes color, and it is as beautiful and charming as in summer.
There are several types of correct trimming hydrangea
- Traditional annual haircut in order to obtain a more powerful and abundantly flowering plants.
- Forming pruning, which allows you to give the bush the desired configuration and optimally position the skeletal branches.
- Sanitary cleaning, which is the removal of old and damaged shoots, dry inflorescences.
- And finally, hydrangea rejuvenation with cardinal pruning, which is carried out on aging or severely damaged bushes.
How to cut a large-leaved hydrangea
Aesthetic or incomplete cutting is best for this type of plant in spring. The fact is that the bush flower formation will occur on last year's shoots. And not all, but their upper part (it will be approximately one third of each branch).
If, by carelessness, these areas are cut off, the plant is unlikely to be able to please us in the summer with lush and elegant flowering. Therefore, you need to know how to trim large-leaved hydrangea.
- If necessary, no more than one fourth of the shoot can be removed from an ornamental shrub. Basically, sanitary cleaning is carried out when old and problematic sections of the bush are removed, last year’s dried inflorescences (if they were not removed in the fall).
- Large-leaved hydrangea from time to time should be thinned in the spring before bud break. This is done in order to prevent thickening.
- Every four years of large-leaved hydrangea requires radical, or anti-aging pruning in spring. At a right angle, all branches are cut off at a distance of about 40-45 cm from the ground.
Some experts advise not to shorten the shoots of large-leaved hydrangea at all in the spring, and, starting from the third or fourth year, to remove three branches to the base. It is permissible. But in this case, you can hardly get a compact and attractive bush.
The nuances of trimming paniculate hydrangea in spring
The bush got its name because the inflorescences resemble neat panicles. And so that they do not look unkempt and untidy, you need to know the rules for trimming paniculate hydrangea.
- Like large-leaved hydrangea, it is cut in the spring before bud break. This period of time is important to catch.
- It must be remembered that the shrub blooms on the shoots of the current year, so during the spring pruning they remove the old branches so that they do not pull the juices from the young shoots, the rest are shortened, leaving three to five buds.
- During the spring pruning paniculate hydrangea remove all shoots growing into the bush or unaesthetic.
Formation of a bush in shtamb
Sometimes the hydrangea can be seen in the form of a trunk: a neat blooming ball adorns the strong trunk. This form can be obtained by properly trimming hydrangeas, applying maximum effort and effort, but there is nothing complicated here:
- It is possible to form a plant by trimming already from the second year. In the spring you need to choose the strongest escape and remove all the rest.
- The escape, which over time should become a shtamb, is shortened to the strongest and barely developing kidney, if you perform the procedure in spring.
- You do this trimming and shortening of the main shoot until it reaches one meter. Usually missing two or three haircuts.
- Then you start to form a ball. To do this, each time you leave four or five strong shoots, the rest must be cut.
- In order for our “tree” not to stretch upwards, it is necessary to pinch the upper bud of the future trunk.
Does hydrangea need pruning?
Hortensia is a shrub (less often a low tree) that can grow without care. In this case, the bush grows heavily with a large number of thin branches, the beauty of the plant and the quality bloom drops sharply, inflorescences lose their pomp and shrink. It is the thin, lifeless branches that are pruned first.
Pruning branches, held in time, will preserve the health of the plant, without losing its inherent decorativeness.
Spring Trim Types
Pruning hydrangea in spring is performed in various ways and at different times. The method of pruning depends on the type of plant and the type of flowering. In most cases, pruning shrubs carried out in the spring. Usually in autumn bloomed inflorescences are cut off, for example, in panicle hydrangea, to avoid breaking branches. Non-frost-resistant species are pruned before covering the plant for the winter.
Spring pruning can start from the moment the snow melted, the main thing is to be in time before the appearance of foliage. Some types of pruning are carried out a little later, so that frozen and damaged shoots, branches and buds are better seen.
The main types of trimming
Spring pruning of hydrangea can be of several types, depending on the intended purpose:
- Sanitary. This treatment is carried out after the leaves have already appeared, then broken, damaged by frost, weak branches and non-flowering shoots are best seen. In the first year of the plant’s life, only sanitary pruning is carried out.
- Stimulating. With this procedure you can achieve beautiful flowering. The procedure for regulating plant density is conducted annually from the third year of the plant's life.
- Formative. In the first three years give shape to the upper part of the plant and the main shoots.
- Rejuvenating. At this stage, all old branches are removed, leaving about 9–11 powerful shoots. If the plant has had pain or has suffered an attack of pests, then all the shoots are cut to 50 cm. After this procedure, the plant will not bloom next year, but it will be able to recover.
The basics of pruning and the formation of a hydrangea tree
A free-growing shrub that, thanks to its lush inflorescences, attracts admiring glances - the hydrangea is tree-like. This species is characterized by large inflorescences in the form of a hat of greenish color, rolling in white. It has many sleeping buds. After planting shoots shoots they are usually pruned, this is done so that the bush grows better and faster. New shoots in a tree hydrangea are formed quickly. Young shoots have many inflorescences. They appear both on the branches of the previous year, and on the underground shoots, which are also able to bloom.
In order for the bush to grow strong and please the owner with beautiful buds, it is necessary to carry out various types of pruning annually.
- Spring must be done sanitary pruning, during which dried, broken, frozen, weakened shoots are removed.
- With the help of thinning pruning trimming occurs shoots. Removed weak and thin shoots that grow in the center.
- For the appearance of strong branches with large buds spend stimulating pruning. Annual shoots pruned so that they have from 3 to 5 buds. If you cut too much, you can get the opposite result: the plant will bloom late, and the inflorescences will be small.
- Once in 6 years should be performed rejuvenating pruning. In spring, shoots of tree hydrangea, which are more than 5 years old, should be cut to 9–12 cm. It is recommended that the old and heavily grown plants do this not at once but for 3–4 years so that the bush does not die.
It often happens that after a harsh winter you have to delete many frozen shootsIn this case, only sanitary pruning is carried out.
A plant under 4 years old in spring is not recommended to be cut due to strong sap flow. This time is best suited to obtain cuttings from the plant. In the first three years, pruning shrubs should be done only after the leaves bloom.
The specifics of pruning hydrangea paniculate spring
Paniculised hydrangea is a large and widely branched shrub. Inflorescences have a cone-shaped shrub. It is frost-resistant, so you can not cover it for the winter. On young branches under 3 years of age from all the kidneys new shoots appear. This plant can be grown as a bush. The underground shoots of the hydrangea paniculata are practically not formed, so it can be formed in the form of a spectacular small tree.
Despite the size of the plant, it is very fragile, so it is necessary to remove dry inflorescences in the fall, otherwise shoots may break under the snow or change shape.
The most important types of trimming paniculate hydrangea
- In the process of spring pruning, thin, withered and frozen shoots are removed.
- Annual shoots are pruned from 3 to 5 buds for better flowering.
- Small thin shoots should be removed in the spring, and on large need to leave some strong shoots.
- A positive effect on flowering pruning shoots last year, as panicled hydrangea quickly increases number of branches with inflorescences, which leads to their decrease.
- This species responds well to crown formation.
- During rejuvenating pruning, shoots growing from one point are selected and all are removed, except for those that grow outside.
If it is right and in time to prune, then the flowering every year will only be more abundant.
The appearance of paniculate hydrangea and the process of creating the necessary form
Trimming this type of hydrangea is done according to the desired shape.
- Standard form. In view of certain features, it is possible to grow paniculate hydrangea in the form of a neat tree with a thick crown. The reason is that this hydrangea from 5 years on the lower branches of the kidney cease to awaken. To grow a standard tree from a hydrangea, you need to choose a sapling with a clear dominant stem. At the age of 3 years, an upright shoot is selected on the plant. It must be carefully tied to the rail, which will serve as a support. Side shoots that form on it in summer, should pinch. Pruning such shoots next spring, as they are necessary for nutrition and the formation of the trunk. When the tree reaches the required size it is cut. Here will be laid the beginning of its branching. From this point on, the upper part of the tree (crown) will be formed from last year's shoots. In the future, it is necessary to reduce the largest branches annually by 2–3 buds until the desired crown shape is obtained. Есть разные сорта гортензии метельчатой, которые имеют различные характеристики. При желании можно вырастить дерево с поникшими или вертикально стоячими ветвями кроны.
- Кустовая форма. To give the plant a bush form, it is necessary to bury the seedling when planting, which will lead to the formation of several processes at once. In the process of growth of the bush will need to cut off weak shoots. To inflorescences do not become smaller, it is necessary to cut off the excess, small branches. Every spring shoots of the previous year should be shortened to 2–4 pairs of buds. To maintain the hydrangea in the form of a bush will require only sanitization.
Necessary activities after trimming
After pruning, the plant must be fertilized with fertilizers, and the soil at the base of the bush is mulched. Spring dressing promotes proper development and the growth of the bush, as well as its strong flowering.
Compliance with the conditions of pruning and creating a crown of hydrangea, taking into account the characteristics of different varieties, will help transform the plot.
Hydrangea paniculata - spring trim rules
This shrub is especially loved for lush floral brushes, painted in delicate colors, and for natural frost resistance.
The advantages also include the fact that the future flowers she lays on young stalks. Young growth from last year's growth is often weakened, so they cut it out without regret.
The basis of the bush form of paniculate varieties are zero shoots - coming from the root. From them choose the strongest, the weak are removed.
The order of removal of branches:
- sanitary - removed broken, diseased, frozen and too old branches,
- rejuvenating - old branches, whose growth has slowed down, and the young shoots from which does not give buds, are cut to a branch of a young qualitative branch,
- thinning - a bush rid of all thin twigs growing inside, not giving full inflorescences lateral stems.
Main pruning - flowering, spend it at the very end of winter, before the start of sap flow, in order to achieve a qualitative increase, strong, guaranteeing the receipt of large inflorescences.
Usually, all branches left over from last year are shortened, leaving 2-3 pairs of buds. They are expected to grow healthy shoots, which will form a floral brush. Their number may be greater if the trimmed base is thick.
Spring pruning tree hydrangea
Early spring is considered the optimal time for the annual arrangement of tree hydrangea.
The algorithm of action is as follows:
- sanitization - the plant is freed from frozen and broken branches,
- rejuvenation - completely cut out branches older than 3 years, especially those whose growth was unpromising,
- thinning - removal of thin stems that grow inward, do not give buds, create excessive bush density, as well as weak zero offsprings.
Pruning flowering - shortening last year's growth so that 2-4 pairs of buds remain on it. They will give a qualitative increase, which will form inflorescences.
Large-leaved hydrangea - features of pruning in spring
Getting to the spring ennobled this species, you need to know what features it has:
- zero shoots grow every year
- branches grow old quickly - the four-year-old is already considered old,
- buds are laid in the apical buds.
In addition, among the representatives of this species there are those who have reduced shoot formation. New varieties, bred by breeders in recent years, have the ability to form flowers in the apical buds in the growth of last year, and the newly grown in the current year.
It should also be noted that individuals hibernating under cover are exposed not only to spring, but also to autumnal shortening of branches.
Therefore, the algorithm of spring works will be as follows:
- sanitary actions - the frozen ends of the branches are removed, as well as all the broken, diseased, dried,
- rejuvenation with the removal of old branches to the base,
- thinning - cutting unpromising overgrowth.
Pruning for flowering at the beginning of the season is not carried out, since it basically coincides with autumn.
The question of when it is better to trim a lush beauty - in late winter or autumn, has no definite answer.
The general rule is that early spring is good for regions with a cold climate. Here, the autumn cutting of the shoots is fraught with the fact that the cuts will not have time to properly tighten before the onset of frost, and the plant will fall ill or die.
Both seasons are suitable for the southern regions, unless other conditions are specified by species or varietal characteristics.
And in any case, it is recommended to remove inflorescences in autumn, because without shelter they will break branches under the weight of snow, and they will cause inconvenience when building protective structures.
Pruning hydrangea in autumn
Although most of the work is in the spring, in the autumn, pruning of hydrangeas is also required. It is necessary in order to divide all the work on the formation and improvement of the plant into two periods. In this case, the hydrangea will transfer the whole procedure safely.
By doing aboutCutting hydrangea in the fall, you need to pay attention to the old, damaged branches, as well as those that grow inside the shrub. They are removed, but in the fall do not touch the young processes. They also cut down almost to the ground shoots, which for some reason were broken in the summer.
The air temperature during this period should be plus 5-10 degrees. For different regions this is the beginning - the end of October. If hydrangea is frost-resistant, it can be cut off in November.
The north of the region, the more gentle pruning of the plant should be in the fall, because the hydrangea does not like severe frosts, and shorter twigs will be less protected from cold temperatures. This is especially true for large-leaved hydrangea, which is thermophilic. The remaining species are considered relatively cold resistant.
Important! It is not customary (especially in cold regions) to carry out the autumn pruning of the plant for the first three years, since the seedling needs strength to withstand and survive the adverse winter conditions. During this period, they do only forced sanitary cleaning.
In the southern regions in the autumn you can act more decisively with the expectation of the next year. Experts believe that in a warm climate, the autumn procedure is even preferable.
All varieties of hydrangeas have their own specifics of autumn pruning.
Features of pruning hydrangea (large-leaved, tree, paniculate) in autumn
Grooming of large-leaved hydrangea should be carried out very carefully during this period, remembering that it is the young twigs that will give shoots next spring, on which flower buds are laid. In the autumn they are not touched (the same applies to paniculate hydrangea).
However, there are separate varieties bred by breeders, where flowers are laid on all the shoots - both old and new. This point should be taken into account when pruning hydrangea in the fall.
The first thing on a bush or shtambe (it depends on how you form the plant) at the bottom you need to tear off all the leaves and cut off the rotting buds of hydrangea. This is necessary so that the lower part is rather stiff, and in the future the bush or shtamb was strong and healthy. The upper part is left leafy until spring.
Then diligently cut out any damaged or poor-quality shoots, because in the snowy winters they quickly break and injure the bush. If branches grow inwards or intersect, they are also removed.
If the shrub requires rejuvenation, then it can be held in the fall. In this case, all the shoots are cut to a stump. But it happens that the bush has grown strongly. In this case, the autumn radical correct pruning of hydrangea is carried out three times, stretching the procedure for three years. Every autumn, about a third of all branches are removed, first of all, old and unpromising fragments.
