Why don't purple hydrangeas bloom in the garden? Aphids on hydrangea

Garden hydrangeas belong to amazingly beautiful and lush-flowering plants that look very impressive on summer cottages, flower beds.

These beauties can reach a height of up to one and a half meters! Both a single hydrangea and a composition of several bushes in the garden will always delight magnificent inflorescences different colors.

This is favored not only by the variety of shades of spherical and corymbose inflorescences, but also by the shape of the flowers themselves. In the center of the flower ball there are female flowers, and larger and brighter male flowers, which consist of four or five enlarged sepals, decorate the edges.

In addition, this plant can be not only a shrub, but also a small tree, and even a liana. The possibilities for site design using hydrangea are endless!

Typically, the flowering period of hydrangea lasts from late spring to early autumn. But sometimes gardeners who planted this plant several years ago do not wait for the inflorescences to appear. It happens that hydrangea blooms poorly, but why is unknown.

Reasons for lack of flowering

Before you look for reasons explaining why garden hydrangea does not bloom and decide what to do, you need to know about some characteristics of the species.

So, tree and paniculate hydrangeas very demanding on living conditions. In addition, young plants will not form inflorescences until they gain strength, and this lasts for years.

It is difficult to say exactly what year after planting hydrangea blooms, because the quality of the soil, the level of lighting, and the regularity of watering all matter.

In most cases, this plant does not bloom due to what's his root system not yet sufficiently developed. If you purchased flowering bush, planted it on the site, and the flowering gradually faded away, don’t be surprised.

Unscrupulous sellers often use growth stimulants to make hydrangeas bloom. As a rule, for another two years after such forced flowering, plants do not release inflorescences, gaining strength.

The second reason is improper pruning of plants. Old varieties of large-leaved garden hydrangeas produce inflorescences at the top of the shoots that grew last year. If you have not bothered to protect the bush from frost for the winter and prepare it for winter, then these shoots will have to be removed due to freezing.

It is quite natural that during the flowering season your hydrangea will not please you with lush inflorescences. Moreover, it will not bloom for several years to come.

Pruning of shoots should be done at the end of October. At the same time, several pairs of young buds are left on the shoots. In spring, these young shoots are shortened again to make flowering more luxuriant.

Garden hydrangea bud formation occurs in the fall. If frost hits at the beginning of spring, when they begin to awaken, they will freeze. It is not recommended to remove the cover from the bush until the air temperature at night reaches -5 degrees or above.

The homeland of hydrangeas is Central Asia, where the climate differs from the domestic one. When purchasing plants in stores, please contact attention to varieties which are well acclimatized to our natural conditions.

The fact is that heat-loving hydrangea may simply not have time to lay new flower buds during our short summer, and therefore will not bloom next year.

Although it seems, at first glance, that caring for the garden beauty hydrangea is not difficult, we must not forget that it is capricious. The expected flowering may not occur, or will be scanty, or the buds that appear will not bloom. There are many reasons why hydrangea does not bloom, let’s consider them in order.

Inappropriate landing site selected

Open spaces, illuminated by the sun almost all day long, are completely unsuitable for cultivation, with the exception of only a few varieties of G. serrata, and it also needs a limit of 6-8 hours a day.

If there is no other option, but you want to decorate your plot with luxurious bushes, you have to resort to tricks: · low planting - the base is located 10 centimeters below the soil level, the tree trunk circle is covered with mulch (peat, sawdust); · choose from the many types of G. paniculata, providing it with regular sufficient moisture, or G. serrata.

Also, heavily shaded corners are not suitable for beauties. In constant shade, hydrangeas bloom very sparsely, and most often the buds do not bloom. All bush varieties do not like wind. They are planted in protected places, but away from brick walls or fences. Such a neighborhood will soon lead to oppression of plants.

It is also necessary to choose a well-drained area, melt or rainwater should not stagnate. You should not plant flowers near large trees - it will suffer from lack of moisture.

If incorrect location is the reason for the lack of flowers, the bush should be replanted, taking into account all the above recommendations.

Incorrect watering mode

Hydrangea, whose Latin name Hydrangea means a container of water, loves moisture. In dry weather, it needs watering so that the soil around its roots does not dry out. It is also important not to overfill it under any circumstances.

Basic rules of watering: ·

in cool weather, watering once a week is sufficient;

· during hot dry periods – once every three days;
· on heavy clay soils moderate watering carried out less frequently; ·
on sandy and sandy loam - more often and more abundantly;

Water for irrigation needs soft water (rain, filtered, or tap water that has stood for at least 5 days).

Each plant requires 1-1.5 buckets of water for watering. Bushes under 3 years of age need additional moisture.

Adaptation of purchased seedling

If you buy a seedling with an open root system (without an earthen ball), fewer problems arise; it will be glad to find itself in the ground again. The main thing is to correctly formulate the soil mixture for it and choose the most suitable place.

Composition of the substrate for planting: ·

fertile land;
turf;
peat;
humus;
river sand.

Everything is taken in equal parts and mixed thoroughly. This mixture already contains a sufficient amount of organic fertilizers, provides good ventilation roots.

It is imperative to bring the acid-base indicator of the soil to normal - for hydrangeas - 5.5-5.6 pH. If the seedling is in a container, the soil from the roots is not shaken off, and the roots are not cut off.

Important! Very often, such babies are fed with chemicals in order to have an impressive presentation. Therefore, in order planting material did not experience severe stress when being in normal conditions, in the first year they contribute nutrients in slightly increased doses - by 3-7%.

Unbalanced feeding

Excess nitrogen will cause the release of young shoots, but they will not have time to harden before the onset of cold weather. As a result, the new branches will freeze, and the flower buds will die with them.

Please note: You cannot feed with nitrogen even when the flower stalks are ripening. This will provoke the appearance of new foliage, which will interfere with the high-quality formation of buds and full flowering. Therefore, fertilizers containing nitrogen are applied only in the spring, when the growing season begins and lush greenery will only be beneficial for appearance, and for photosynthesis. The remaining fertilizing (for a total of 3 or 4 seasons) is carried out with potassium and phosphorus salts, and before winter they add organic matter - compost or rotted manure.

Other reasons

1. Incorrect autumn pruning or improper shelter for the winter Depending on the variety, flower stalks are formed on shoots of the past or current year.

That is why autumn pruning is carried out according to the appropriate rules. For those varieties whose flowers form on last year's branches, timely shelter for the winter is also very important. In order for the young shoots to become stronger and woodier before the onset of cold weather, about 3 weeks before sheltering, all leaves (both old and young) are removed approximately to the middle of the height of the bush.

2. Alkalinization of soil. It also happens if the flower initially grows in an acidified environment. To avoid this, you should use complex fertilizers designed specifically for hydrangeas. They contain additives that regulate soil acidity.

3. Diseases and pests. Although all hydrangeas have increased resistance to diseases and pest attacks, errors in care can lead to various types of damage.

The most common disease is chlorosis, a disorder in the absorption of iron. It is also possible that powdery mildew, especially at the end of summer, when it is still hot during the day, and at night the air temperature drops significantly.

Of the pests that settle on weakened bushes, the most common “guests” are aphids and spider mites. As a result, it turns out that hydrangea not only does not bloom, but it also does not form buds.

4.Unsuitable variety. Many varieties are completely unadapted to the short, cool summer of the northern and northwestern regions: they grow, produce lush greenery, but do not have time to lay and fully form flower buds.

To plant on your site, you should definitely choose those varieties that actively bloom in open ground in this particular region (zoned).

If the choice nevertheless fell on a more heat-loving plant, it makes sense to grow it in winter garden or in a large flowerpot to extend the warm season for it by bringing it indoors.

The main thing when buying hydrangeas- choose the right variety, which in the climate of the region will be able to take root and survive the winter cold. If the variety is chosen correctly, the lack of flowers may be caused by one of the following factors:

Unsuitable climate - hydrangea is a fairly heat-loving plant; transplanting to new conditions may experience stress. In an unusual climate, generative buds will not develop. Before buying a flower, you need to find out in what conditions it grew.
Insufficiency of the root system: young hydrangeas have rather fragile and weak roots; after transplantation, such plants may not bloom for two to five years.
Young plants do not produce flowers; for flowering, the age of hydrangea should begin at 5 years.
Incorrect pruning - with annual improper pruning there will be no flowers, or there will be very few of them.
Cold - the plant must be covered for the winter, acting carefully and carefully. If you do not cover the hydrangea enough, the shoots will freeze; if you do it too tightly, there is a risk of damaging the branches.
Inappropriate feeding may be one of the reasons why flowers do not bloom.
Poor soil - the plant is quite demanding on the quality of fertilizers and the soil in which it grows.
Artificial stimulation of flowering - if before sale the flower was drip-fed with fertilizers to simulate lush blooming species, V next year There may be no flowers at all. In order for a bush to start bearing flowers, it needs proper care.

By providing garden hydrangeas with proper care, you will get an excellent decoration in the garden, and the fragrant lush inflorescences will delight the eye for a long time. Let your hydrangea bloom as long as it wants!

Please note this:

Hydrangea or hydrangea (Hydrangea) belongs to the class Hydrangeaceae. Under natural growing conditions, it can be found in the countries of East Asia, North and South America, as well as in the Himalayas. It's very beautiful ornamental plant, having specific feature. Its original inflorescences in those species that are white or cream in color become red, burgundy, raspberry or cherry with the onset of autumn. Also, their shade depends on the composition of the soil. If you enrich the soil in the area where flowers are planted with aluminum sulfate, they will turn blue or blue. And if you water the plants with a solution of potassium permanganate, the inflorescences will turn pink.

Despite the fact that hydrangea is a favorite of most gardeners for its beautiful and long flowering, she is enough capricious plant. At the same time, different species have their own rules of care, non-compliance with which leads to the absence of buds. This article answers the question: “Why doesn’t garden hydrangea bloom?”

Reasons for the lack of flowering of garden hydrangea

Reasons for lack of flowering garden hydrangea there are many. They can be both general and individual for each species. Therefore, before planting this on your site beautiful flower you need to study its features and rules for caring for it.

Poor place to plant a seedling

Since garden hydrangea is perennial shrub who does not like transplants, then the place for her landing should be chosen in accordance with her preferences. Otherwise, the plant will develop poorly and there may be no flowering. The basic rules for choosing a place to plant garden hydrangeas can be considered the following:

Hydrangea does not like transplants

- The site should be located so that in the first half of the day it is illuminated as much as possible. After lunch, plants should be in partial shade. If this is not possible, then you need to create additional shading for the hydrangeas before flowering begins in the afternoon. Plants planted too sunny place, can get sunburn, and those that grow in constant shade bloom poorly.
- Plants must be protected from winds and drafts, which inhibit their development. The optimal place would be to plant near a house, gazebo or other garden buildings.

It is not recommended to plant hydrangea near other large shrubs or trees. It is quite moisture-loving, and other plants will actively absorb water, which can lead to a lack of moisture.
Hydrangea has a superficial root system. Therefore, if it is part of flower arrangements, it is desirable that its neighbors are flowers whose roots grow deep. Otherwise, they will not allow the plant’s root system to fully develop.

Hydrangea is demanding on soil composition

The composition of the soil is of great importance for garden hydrangea; it should have an acidic or slightly acidic reaction. The soil should be nutritious, loose and well drained. It should not contain lime, which inhibits the development of the plant. Before planting hydrangeas, it is recommended to make deep holes in the dug area and fill them with the following soil mixture:

turf land - two parts;
humus - two parts;
peat - one part;
coarse sand - one part.

Lack or excess moisture

Hydrangea is a very moisture-loving plant, so watering for it is important. It should be carried out weekly, pouring 20 liters of water under each adult bush. If the weather is too hot, watering is carried out twice a week.

The water should be soft, because... hard has a negative effect on the condition of the plant. Tap water Before watering, you need to let it sit for at least five days.

Lack of moisture can cause foliage to wilt and buds to fall off. Prolonged drought leads to the death of hydrangea. But you shouldn’t overwater the soil; you need to let the top layer dry. Otherwise, rotting of the root system and the development of various diseases may occur.

Adaptation after disembarkation

Planting garden hydrangea in open ground is best done in early autumn. IN in this case During the winter, the plant has time to take root well and get used to the new place of growth. Since hydrangea does not tolerate transplantation well, in order for it to quickly take root, several rules should be followed:

It is best to plant hydrangea in early autumn.

When removing the plant from the container, you should preserve the earth as much as possible so as not to damage the root system.
After planting, you need to mulch the soil with peat or sawdust and provide additional shelter for the plant.
The soil should always be slightly moist, but without overflowing.

If new leaves appear on the hydrangea within a month, it means the adaptation was successful. In the future, it is important to properly prepare young plants for winter in order to preserve them until spring.

Hydrangea planted in autumn period, as a rule, blooms already at next summer and is more resistant to disease and pest damage. Those plants that are planted in the spring bloom only after 2-3 years of growth, since their first summer is spent adapting.

How should the root system develop?

Hydrangea is distinguished by a widely branched root system, which must be taken into account when planting

Hydrangea has a shallow, widely branched root system. Therefore, it is advisable that the remaining plants are planted at a distance of at least one meter from it. In this case, the plant will have enough space and moisture for the full development of the roots, and, consequently, the above-ground part.

Incorrectly selected fertilizers

Garden hydrangea is primarily valued for its bright, lush and long-lasting flowering, which can only be ensured proper feeding. Also, additional nutrition is required because the bushes of the plant grow quite large. So they quickly absorb useful material from the soil.

Fertilizing begins in the spring, using complex mineral fertilizers every two weeks. They can be alternated with organic matter, such as slurry. To do this, manure is diluted with water in a ratio of 100 grams per 10 liters of water. This will ensure full growth of green mass.

At the beginning of flowering, nutritional complexes that do not contain nitrogen, such as superphosphate, are used. This is required so that the active development of buds and not foliage occurs. An excess of nitrogen in the soil prevents young shoots from becoming woody, and they may die during wintering.

Fertilizers are applied weekly. This is necessary for the formation of new flower buds. Once a month you can water the hydrangea with fermented milk drinks (kefir, yogurt, etc.).

With the beginning of autumn, fertilizing should be stopped so that the plant can calmly enter the dormant period. In September, you can add ash to the soil at the rate of 100 grams per square meter. It is also recommended to add 15 kilograms of manure under each bush. This will serve as additional feeding in the spring and will protect the root system during wintering.

Frozen buds in winter

Hydrangea blooms on last year's shoots, on which flower buds are formed during the summer and autumn. Therefore, if they freeze in winter, the plant will not bloom. In this regard, it is important proper preparation hydrangeas for wintering. First of all, you need to prune according to the type of plant, and then cover it in accordance with the following recommendations:

The reason for the lack of flowering may be frozen buds

Low bushes are completely covered with peat and covered with covering material.
Heavy boards are laid around young tall plants and nails are driven into them. Then the bushes are rewound with ropes, carefully bent and secured with nails. After this, they are covered with sawdust and covered with spruce branches. A sheet of iron or other heavy material is laid on top of the shelter and then covered with snow.
Adult hydrangeas are not bent so as not to harm the plants. They are simply completely wrapped in covering material and tied with rope. They install around the bushes metal mesh, dry leaves are poured inside, and the outside is covered with plastic film.

The cover should be removed after the spring frosts have ended, as they can also damage the kidneys.

Unsuccessful bush pruning

Unsuccessful pruning of a bush can completely stop flowering

Hydrangea pruning must be done correctly. If flower buds are removed during this process, the plant will not bloom. In the first two years of growth, it is not recommended to do it at all. Each species has its own timing and methods for pruning bushes.

How to prune correctly and prepare for wintering

When pruning garden hydrangea, consider the following recommendations:

Large-leaved hydrangea is pruned at the beginning of the autumn period after flowering. In this case, only the inflorescences, remaining buds and dried stems are removed. Pruning of shoots does not occur in the fall; it is done in the spring after the buds open, so as not to harm the flowering.
Tree hydrangea is pruned in late autumn. Young shoots are shortened so that at least four buds remain on them. This will allow them to develop and bloom well in the spring. Old, dry and damaged stems are completely removed. Because this type tends to thicken, then at this time the crown of the bushes is formed. To do this, excess branches, usually located inside the plants, are cut out. You also need to remove all remaining inflorescences.
Paniculata and oakleaf hydrangea are pruned in the spring. In autumn, only inflorescences and buds are removed.
Petiole hydrangea radically pruned in spring and, if necessary, in summer. This is done to form beautiful crown due to the formation of additional side shoots. In the autumn, only the inflorescences and weakened and dried stems are removed. Also in the fall, the side shoots are shortened slightly.

In order for the hydrangea to comfortably overwinter, after pruning, the plants are covered to protect them from frost.

Diseases and pests

With proper care, hydrangeas form strong bushes that are rarely infected by diseases and pests. If the maintenance rules are not followed, plants are affected by the following diseases:

If agricultural practices are followed, hydrangea is rarely affected by pests and diseases

Powdery mildew. When it occurs, the foliage becomes covered gray coating, which darkens over time. Then the leaves begin to wither and fall off, and the shoots become covered with burgundy spots.
Gray rot. The disease can be recognized by the presence of brown spots on the plant. They grow very quickly, and then the hydrangea dries out.
Chlorosis. Foliage begins to discolor, curl and fall off. At the same time, the veins remain bright green color. Buds and flowers become deformed, change color and fall off.

If signs of these diseases are noticed on the hydrangea, you should immediately begin treatment. To do this, you need to remove all affected leaves and parts of shoots. After this, treat the plants with a fungicide solution and pour it into the soil, since the root system may also be damaged.

Among the pests that can be dangerous for hydrangea are spider mites, scale insects, and aphids. If they are found on the plant, you should wash it with a solution of green or laundry soap. After this, spray with infusion of onion, garlic, tobacco or wormwood. If the data folk remedies do not help, you need to treat the hydrangea with an insecticide solution.

Wrong variety selected

When choosing a hydrangea variety, you need to take into account climatic conditions.

Hydrangea has species and varieties with varying degrees of frost resistance. Therefore, when choosing a plant, you should take into account the climatic conditions of the area. In regions with warm climates, various species can be bred. For northern latitudes Frost-resistant plants are suitable, for example, numerous varieties of tree hydrangea. Heat-loving species will freeze to death without proper care.

Reasons for the lack of flowering in species and varieties

Since all types and varieties of plants (tree-like, large-leaved, paniculate and others) belong to the same family, the rules for planting and caring for them are no different. Accordingly, the reasons for their lack of flowering are the same. The only difference is the pruning rules.

Reasons why garden hydrangea does not bloom for several years

Do not worry if the planted garden hydrangea does not bloom for several years. The fact is that often the first flowering occurs only after 2-3 years of growth. Some varieties of paniculata hydrangea bloom only in the 6th year of cultivation. If, however, after this time, flowering has not occurred, then you need to reconsider the growing conditions of the plant and the rules for caring for it.

Reasons why hydrangea does not bloom indoors

Indoor hydrangea, grown in compliance with all care rules, is also characterized by abundant and long-lasting flowering. The reason for its absence may be an incorrect rest period. Therefore, when growing hydrangea in room conditions The following recommendations should be followed:

In autumn, at the end of flowering, you need to remove all inflorescences and dried shoots.
Send the pot with the plant to a dark place where the air temperature is maintained at +10 degrees.
Stop fertilizing.
Watering is carried out once every two weeks.
At the beginning of March, place the plants in normal growing conditions.

In hydrangeas for which the above rest conditions are met, lush flowering, which lasts from late spring to early autumn.

Hydrangea is a very spectacular plant

Hydrangea is a spectacular plant that will decorate any garden plot. At the same time, it refers to medicinal plants and has anti-inflammatory, antibacterial, diuretic, wound-healing and cleansing effects. Its high decorativeness made it very popular in landscape design. It is planted in flower beds, lawns, and hedges are created. With the help of varieties of petiole hydrangea they make original decor for gazebos and walls. At the same time, it does not require large physical and time expenditures for its care; the main thing is to know what to do if the hydrangea does not bloom.

You can get acquainted with the correct pruning of hydrangea in the proposed video clip. Enjoy watching!

Hydrangea - popular among gardeners decorative flower. It belongs to the category of capricious crops. Errors in growing technology lead to a lack of flowers. There are several reasons why the plant does not bloom. It is important to diagnose them correctly and then eliminate negative factors.

Features of hydrangea cultivation

Hydrangea is grown as a climbing vine, small tree or shrub. The plant has many varieties. The variety of shades and shapes allows you to create a unique decorative combination in the flower garden. You need to figure out why hydrangea doesn’t bloom in the spring, when you notice the absence of buds.

Beginning gardeners may encounter the following problem: they bought ready-made flowering plant in the store, but at home it withered. It is not possible to achieve the appearance of new buds. The reason for this was most likely special means, which stimulate flowering, but greatly deplete the strength of hydrangea. After treatment, the plant may not form new flowers for several more years.

Advice. In this case, you can help the culture by adding a growth activator.

If you purchase a young specimen and plant it yourself, it can bloom in the first summer after reproduction. However, without proper attention and care, you may be left without flowers even in the second season if the cutting turns out to be weak and has not grown stronger in the first year. And in this case, growth activators help. The drugs allow:

Hydrangea blossom

strengthen and develop the root system;
form stems and twigs;
provide an increase in greenery.

Feeding hydrangea: the basis for full flowering

The correct technology for fertilizing hydrangea will help to grow a plant that can bloom normally. The flower needs the first feeding immediately after planting - with a weak solution of organic fertilizer for good adaptation. During the growing process, fertilizers are applied according to a certain pattern.

In early spring, the crop needs a lot of nitrogen. This mixture works well:

urea - 1 tbsp. l.;
Potassium sulfate - 1 tbsp. l.;
water - 10 l.

Attention! Watering is carried out at the rate of 5 liters per 1 bush.

An alternative is slurry diluted in water (1:10). Later, at the stage of bud formation, the plant is fed mineral complexes with a high content of phosphorus and potassium. To further strengthen the bush, pour potassium permanganate solution over the root zone and the stem itself. The procedure must be repeated three times. In this case, there should be no situations where hydrangea does not bloom.

In summer, the shrub must be treated with a strengthening complex agent for flowering crops. Nitrogen must be used carefully during this period. Its excess will lead to strengthening of the greenery and the inflorescences themselves, which will negatively affect the strength of the branches. Total number fertilizing in the summer months is limited to 3 times.

During flowering, gardeners also use non-standard fertilizers:

lactic acid (yogurt, kefir, whey);
soaked sour bread.

Advice. In autumn, hydrangeas need to accumulate potassium and phosphorus, so repeat the course of applying mineral fertilizers.

How to understand why hydrangea does not bloom

The main reasons for the absence of buds in an adult hydrangea:

Before experienced gardener There is no question about hydrangea flowering. The main factor in this is proper care of the plant.

How to make hydrangea bloom: video

Often even experienced flower growers They are faced with the problem of a lack of flowers in the garden. This plant is demanding on growing conditions. The slightest mistake in care can lead to its buds withering and falling off, or even not appearing at all.

To ensure long and abundant flowering of young and adult bushes, you need to know what factors most often affect their flowering. In this case, you can quickly fix the problem when it appears.

The main reasons for the lack of flowering and their solutions

Most often, novice flower growers make the following gross mistakes in flower care. Why garden hydrangea does not bloom:

Anomalies in the growth and development of the root system are often encountered, especially in newly acquired plants. This leads to disruption of the development of the bush and lack of flowering.

Let's look at the reasons why hydrangea does not bloom in more detail.

Preparing for winter

Hydrangea does not tolerate frost. Any drop in air temperature below 0ºC can lead to freezing of flower buds. In this case, the plant will not bloom. To protect the bush from frost, it needs to be covered for the winter.

Without waiting for autumn frosts, the leaves are torn off the bush, the branches are tied together with a rope and wrapped in covering material. The bush is bent to the ground and covered with spruce branches. In the spring, it is gradually freed from spruce branches, but is finally opened only with the disappearance of frost and the onset of warmth.

Trimming

In order for the plant to bloom, it must be pruned correctly. In spring, dry, old and weak branches are pruned.

All well-developed shoots from last year are not touched. Usually it is at their tops that flowers form. If an inexperienced gardener trims these shoots, the plant will not form buds and will not bloom.

Top dressing

Hydrangea does not respond well to excess fertilizer in the soil. It is especially harmful to apply nitrogen fertilizers to the soil in summer and early autumn.

They are used to enhance the growth of green mass and do not promote flowering in any way. A fast growth shoots in the fall leads to the fact that they do not have time to ripen before the cold weather and freeze.

Proper feeding of the plant is carried out several times a season. At the end of spring, nitrogen fertilizers are applied to enhance the growing season. In summer, fertilizing with potassium-phosphorus fertilizers is used to stimulate and maintain flowering. At the beginning of September, potassium-phosphorus preparations are introduced to strengthen the shoots and prepare for winter.

Root development and flowering

To flower, the bush must have a powerful root system. If the roots are poorly developed, there is no hope for early flowering. Bushes that are too young or overfed with fertilizers can take several years to form roots. And only after that such bushes bloom.

Choosing the right place to plant a bush and caring for it will allow you to overcome all difficulties and achieve annual flowering.

The flowering of a bush can also be affected by:

Insufficient watering;
High air temperature;
Excess or lack of sunlight;
Heavy clay soil.

Reasons for the lack of flowering in some species and varieties

Different types of hydrangea have their own reasons for the absence of flowers and buds, unique only to this variety. Among garden hydrangeas, the following are especially popular:

Let's look at the most likely reasons why they don't bloom.

Paniculate hydrangea is the most frost-resistant species. It tolerates cold so easily that it does not need to be covered at all for the winter. Its buds do not freeze over, since the inflorescences form on the shoots of the current year. However, this species may not bloom for some other reasons.

The main reason why paniculata hydrangea does not bloom is the unsuitable composition of the soil.. Heavy loamy soil with weak acidity is more suitable for such a plant. Light sandy soils are not acceptable for this species.

Also, very often the plant refuses to bloom due to lack of nutrition. Therefore, special attention must be paid to feeding.

Why large-leaved hydrangea does not bloom: most often due to freezing of shoots and buds. There are many varieties of this species that have varying winter hardiness.

While some of them can be grown in open ground, covered for the winter, others freeze out even with careful covering. Such varieties can only be grown in indoors like potted plants.

Pruning large leaf hydrangea must also be carried out carefully. Flowers form on last year's shoots, which cannot be touched during pruning. If you shorten them, the flower buds will be removed and the plant will not bloom.

This species is quite frost-resistant. However, if the bushes are not covered, in severe winter conditions most of the flower buds will freeze. In summer, a frozen bush will not bloom. Therefore, the plant needs to be covered for the winter.

This species needs to be fed regularly., first with fertilizers for leaf growth, then with fertilizers for flowering. Without feeding, the plant will refuse to bloom.

The reason why tree hydrangea does not bloom may be improper watering. In overdried soil, especially in the summer heat, such a bush develops very slowly and never blooms.

Garden hydrangea has refused to bloom for several years now.

Your garden beauty pleased you with its annual flowering, but for several years now there have been no flowers on it. What is the reason? If the bush was protected from frost and properly fertilized and watered, the most likely reason for the lack of buds is diseases and pests. A plant that is sick or damaged by harmful insects will not bloom.

Garden hydrangeas are inhabited by aphids, spider mites, weevils and many other pests. To kill insects, it is recommended to treat the bush with insecticides.

Hydrangea is most often affected by viral mosaic disease and fungal diseases : downy mildew and gray mold. To destroy fungi, the bush is treated with fungicidal preparations. At viral infection all affected areas of the plant are cut out and burned.

Proper feeding of garden hydrangea for flowering

What to do if garden hydrangea does not bloom - perhaps the reasons are feeding. Feeding hydrangea is a mandatory procedure for proper growth and flowering. Spring, summer and autumn are fundamentally different in the composition of the fertilizers used.

At the beginning of spring When leaf mass is actively growing, the plant requires nitrogen fertilizers. Usually a mixture of urea and potassium sulfate is used. One tablespoon of these substances is diluted in 10 liters of water. An adult hydrangea bush requires about 5 liters of solution. Sometimes slurry is used for irrigation, which is diluted with water in a ratio of 1:10.

At the end of spring When the period of bud formation begins, it is recommended to feed the plant with potassium-phosphorus fertilizers.

Superphosphate gives the best results. One tablespoon of this substance is dissolved in 10 liters of water. You can also use any other mineral complex fertilizer.

During summer period , when the plant is actively blooming, it is fed 2-3 times with special fertilizers for flowering plants garden plants. It is also useful to acidify the soil in the place where the bush grows.

To do this, use whey or citric acid. The serum is diluted with water in a ratio of 1:3. Citric acid take on the tip of a tablespoon and dissolve in 10 liters of water.

Early autumn To strengthen the shoots and prepare for winter, potassium-phosphorus fertilizers are applied. Dissolve 1 tablespoon of potassium sulfate and superphosphate in 10 liters of water and water the hydrangea bushes.

Now you know why hydrangea doesn’t bloom in the garden, but what to do if you have a houseplant?

Why doesn't hydrangea bloom indoors?

In indoor conditions, the following reasons are possible due to which hydrangea refuses to bloom:

Wrong choice of lighting;
Unsuitable soil composition for the plant;
Lack of moisture in the soil and air;
Sudden changes in temperature;
Bush age.

So that the plant in the room blooms every year, it must be kept in a lighted place, but direct sunlight should not hit the leaves. If there is too little or too much lighting, flowering will most likely not occur.

The plant loves acidified soil. Also, for indoor varieties, it should not be very heavy. Clay soil won't do.

It is better to choose a purchased fertile soil mixture without clay, but with a small amount of peat. Also, we must not forget about the annual transplantation of the bush in new soil so that it blooms long and abundantly.

The flower does not tolerate dry soil and too dry air. To create optimal conditions for its growth and flowering, it is necessary to keep earthen lump always keep the pot moist, and spray the leaves with settled water.

A sharp change in temperature in the room where the flower grows should not be allowed. In such conditions, it does not grow buds. If the buds have already formed, then a sharp drop in temperature may cause them to fall off.

Over time, the plant, even with good care, stops blooming. It is recommended to grow the bush for no more than 4-5 years, after which it is better to replace the plant with a young one. You can read more about caring for hydrangea at home.

Blooming hydrangea is a real decoration garden landscape: with the help of this flower you can make picturesque and original any plot. However, sometimes gardeners are faced with the fact that an ornamental plant refuses to bloom. Why hydrangea does not bloom, what the problem may be related to and how to solve it - we will find out from the article.

In most hydrangea varieties, the root system “matures” 2-3 years after planting: then flowering begins. But there are varieties that take about 6 years for the roots to grow and develop. If the hydrangea does not bloom at all, the following reasons for this phenomenon are possible:

wrong choice of variety;
incorrectly chosen rooting site;
adaptation period after planting/transplantation;
insufficient watering;
improper pruning - usually too radical;
improper feeding of bushes;
freezing of the buds during the winter;
pest damage, diseases.

Variety selection

Today, scientists know about 70 species and varieties of plants. There are hydrangeas in the form of herbaceous low shrubs, there are tree-like varieties, vines, evergreen and deciduous varieties. And although the choice is extensive, in our climate many of the varieties cannot be grown normally in open ground.

There is a fairly large part of hydrangeas that simply do not have time to bloom in the short summer. And if you purchased just such a variety, you may never wait for flowering.

Only a limited number of hydrangeas from all the variety that exists are suitable for our climate. Will fit well tree species, groundcover and paniculata. These are the most unpretentious and hardy species, which can bloom even in short, cool summers.

Poor choice of rooting site

When planning to plant hydrangea in open ground, a place for it must be selected taking into account all the specific requirements. Thus, the plant feels extremely uncomfortable in completely open places, especially under scorching heat. sun rays. In such conditions, even if the hydrangea blooms, this period will not last long: the delicate petals will simply burn out, wither and fall off.

If the area is entirely sunny, plant paniculata hydrangea: this species tolerates the sun better than others. However, do not forget about abundant regular moisture: only under this condition will the plant bloom well.

IN shady place It’s not worth planting a flower either. In conditions of almost complete absence of sunlight, it is unlikely that large-leaved (or any other) hydrangea will delight you with abundant flowering. In this case, the plant will also develop poorly.

Under the shady crowns big trees Therefore, it is not worth planting hydrangea. In addition to the fact that the crown of neighboring trees will create a significant shadow, practically impenetrable to the sun's rays, it will also cause water to the roots powerful plants will be taken away.

The optimal landing site will be an area illuminated and heated by the sun in the afternoon. Hydrangea planted in such a place will delight you with especially long, abundant flowering. Optimal lighting thus - partial shade or diffuse.

If the place is chosen incorrectly, and the flower has already taken root, there is nothing left to do but replant it. However, first think about whether there is any other way to correct the situation: after all, hydrangea tolerates transplantation very poorly.

Adaptation

Hydrangea has difficulty adapting to a new place, which is why it is transplanted only in the most extreme cases. Often, the first time after planting, the shrub wilts, stops developing, and its flowering either slows down or stops. In most cases, after a certain period, the flower adapts on its own, takes root, and continues its growing season at a normal pace.

If the hydrangea has wilted after being transplanted into open ground after purchase, most likely it is due to the lack of the usual abundant fertilizing, which was supplied to the plant in the store/nursery. Often sellers overfeed a flower so that it looks more beautiful and lush when sold: naturally, after it gets into ordinary land, hydrangea wilts.

In severe cases, not only a lack of flowering is possible, but also the death of the plant. To avoid these sad consequences, it is necessary to make the plant’s adaptation more comfortable. For this:

When replanting, do not cut the roots and do not shake off the old substrate from them;
Mix the soil remaining in the store container with garden soil and pour it into the hole.

The first time after planting, feed the flower more abundantly to facilitate the adaptation process. But gradually reduce the dosage: this way, getting used to a normal diet will go unnoticed.

Lack of moisture

Hydrangea is an extremely moisture-loving flower; without water it will not last long. Even its name is translated from ancient Greek as “vessel of water.” If there is not enough moisture, the hydrangea will refuse to bloom, and its leaves will wither and wither. The roots should always be moistened: they should not dry out.

Let's say more: if the hydrangea is not watered during the dry summer heat, it may completely die. You understand that in this case there can be no talk of flowering. Recommended watering frequency: once a week in normal weather and every three days in drought. Special attention We recommend that you give it to young hydrangeas that are not yet a year old: at this tender age, the plant is especially sensitive to the lack of lag.

If the soil contains a lot of clay, water less often. In a dense substrate, water often stagnates, which is also harmful to the plant and causes rotting of the roots.

Incorrect pruning

Hydrangea should be trimmed very carefully, understanding what and how to do. If at autumn pruning remove the rudiments of future buds, next season flowering will either be less lush or will not happen at all.

Young hydrangeas are not pruned until the first flowering, and adults - only when necessary. In the autumn, not all varieties and types of hydrangea can be pruned, and in the spring we recommend postponing the procedure to a later time so that the buds are not damaged by return frosts. If pruning of the perennial is neglected in principle, buds may not form at all;

The procedure requires experience and skills:

it is necessary to thin out the bush - otherwise the inflorescences will be crushed and become rarer;
small branches growing inward require mandatory removal, since they do not bloom, but only thicken the crown;
For abundant flowering it is necessary to shorten last year’s shoots, leaving no more than 1-3 healthy, strong buds on them;
shoots older than 4-6 years no longer produce inflorescences, so they must be removed when pruning.

Important: if the shoot is strong and thick, you can leave three buds on it, if it is thin and weak - only one.

At spring pruning no need to remove shoots from last year's forcing - strong and healthy. It is on them that the bulk of the inflorescences will form this season. In autumn, remove only dried buds, mud, broken and damaged branches. Formative pruning after flowering is not necessary.

Top dressing

Garden hydrangea reacts extremely negatively to overfeeding. Particular harm Plant flowering is caused by excess nitrogen in the soil. This mineral is useful for the rapid growth of greenery, but has a negative effect on the formation of buds.

How to feed correctly:

at the end of spring, add nitrogen to speed up the growth of foliage and the growth of young shoots;
in summer, exclude nitrogen and use potassium phosphate supplements, which activate the formation of flower buds;
In the fall, focus on potassium, which will protect the plant’s roots from freezing in winter.

We recommend using urea as a nitrogen-containing preparation. It is best to dilute the drug with water and potassium sulfate and apply it in the spring. If there is no urea, slurry diluted with water (1:10) is also suitable. It is better to use mineral complexes as a source of potassium and phosphorus.

Tip: when you plant a plant in the ground from a store container after purchase, be sure to feed the flower with a root growth stimulator. This measure will help the plant more easily adapt to a new place and take root.

Keep in mind that certain minerals can control the color of hydrangea buds. So, lime is useful if the hydrangea is pink: the flower petals will become brighter. The addition of alum will give the buds a blue tint.

Shelter for the winter

If the hydrangea is not properly prepared for winter, its buds and roots may freeze. Thus, flowering will not be seen in the next growing season. To avoid problems, in the fall, even before the cold weather, they begin to prepare the flower for winter. If the climate is relatively warm, it will be enough to trim the inflorescences and then cover the shrub with agrofibre. If the winters in the region are frosty and long, the hydrangea should be covered warmer and the roots should be buried.

Leaving a flower without any shelter for the winter is unacceptable: freezing in this case can be critical and destructive. Even frost-resistant paniculate hydrangea It should not be left without protection: it is better to take preventive measures than to allow the roots to freeze out.

Pest and disease damage

The reasons for the lack of flowering may also be associated with diseases and pest damage. Typically, most infections are transmitted through planting material. That is why it is best to purchase hydrangea seedlings from trusted and reliable nurseries, and not from private traders.

In addition, diseases often occur if the plant is kept in conditions high humidity. Although hydrangea is a lover of water, excess moisture inevitably leads to the development of rot and the proliferation of fungus. The situation is aggravated by dense plantings.

Chlorosis is one of the most common diseases affecting hydrangea. The pathology manifests itself as yellowing of the foliage, but in advanced cases it can lead to a lack of flowering. Chlorosis occurs due to metabolic disorders in plant tissues: this usually occurs due to a lack of iron. To cure a flower, you need to feed it with iron-containing fertilizers and spray it with appropriate preparations. Although this treatment gives an effect, it is not immediate: you will have to wait some time until the bush acquires its normal color.

Hydrangea can also be affected by a harmful fungus: fortunately, this happens quite rarely. Typically, fungal diseases are associated with certain rots: root, stem. Prevention and treatment are based on the use of copper-containing drugs (for example, HOM).

For abundant flowering of hydrangea it is very important good development its root system. If the roots are weak, it is unlikely that you will be able to enjoy beautiful bright buds in the near future. Plants that take the longest to form after planting and overfed with fertilizers.

Carefully select a place for planting, as if you choose the wrong one, you won’t see any flowering. Well, hydrangea transplants are extremely difficult.

You should not plant a flower under the roof of a house: in the spring, falling snow or icicles can break its branches along with the rudimentary buds. This way the flowering will be much less abundant.

The area in the garden where hydrangea is planted should have fairly loose, permeable soil. A dense clay substrate is not suitable in this case: it must first be loosened with sand and peat.

If you are an inexperienced gardener, we recommend that you start with the Grandiflora hydrangea variety. This variety is time-tested: its flowering is quite predictable, expected and, with proper care, almost guaranteed. In addition, Grandiflora can be either paniculate or tree-like - choose any type to your taste.

When planting or replanting, be careful with the plant's rhizome. The hydrangea root is fragile and brittle: if it is damaged, the adaptation process will be greatly delayed. More significant harm in the form of illness and death is also possible. Remove the bush from the ground only together with the earthen clod and support the latter from below.

The flower must be watered regularly and quite abundantly. Particular attention should be paid to this procedure in the first year of the flower’s life, as well as in conditions of severe summer drought. After watering and rain, we strongly recommend loosening the soil in the garden bed. In this way, the permeability of the soil will be restored, which is important for the flower. At the same time, there will be fewer weeds.

We learned why hydrangea refuses to bloom and what to do about this problem. As you can see, the reasons are probably different: first you need to understand exactly what caused the lack of buds in a particular case. And only then decide what measures to take. This approach will yield positive results in the most shortest time, and will return flowering to your pet.
