Garden hydrangea flowers do not bloom. Why don't hydrangeas bloom? Powdery mildew of hydrangeas

When propagating flowers in the garden, you should follow the rules of caring for them. If the slightest mistake is made somewhere, the plants either wither or do not bloom for a long time. This happens with the whimsical hydrangea - a classic note in landscape rock gardens. This flower shrub, originally from Japan, has taken root in Russia, but the distinctive climatic conditions of domestic regions make adjustments to its cultivation.

Reasons why hydrangea does not bloom

Every gardener almost always expects hydrangeas to bloom in the year of planting. Indeed, according to descriptions of caring for flower shrubs, it lasts from mid-spring to late autumn. Depending on the species, the plant produces beautiful pitcher-shaped inflorescences of purple, pink, white, lilac, and red.

Hydrangea is the most delicate decoration of gardens and flower beds. However, it is not always possible to achieve this effect. Why? The answer from experts to this question is simple - the main reason for the undesirable phenomenon is a violation of agricultural technology. During the growing period of hydrangea, mistakes are made - the needs of the plant itself are not taken into account.
So, why is Hydrangea so picky? It turns out that the flower bush does not have many needs, and there is always a chance to change everything for the better.

Hydrangea flower bed and reasons for the lack of flowers:

Hydrangea has difficulty coping with climate change. This is especially common in cases where the flower is grown in greenhouse conditions and then planted in open ground.
Inadequate development of the root system of seedlings can affect the number of inflorescences and cause their complete absence. This is observed if the hydrangea is in the first year of planting.
Perennial hydrangea shrubs in early spring or late autumn are circumcised. If pruning is done incorrectly, flowering cannot be expected.
Hydrangea is a heat-loving plant, so it does not tolerate cold and low temperatures.
Consequently, if wintering conditions do not meet the requirements of the shrub, it loses strong shoots, which simply freeze and become unviable.
Hydrangea loves water very much, even its name Hydrangea translated from ancient Greek means a vessel with water. Poor watering also affects the number of inflorescences, their size, and their absence.
Growing any flower in climatic conditions, different from the weather conditions in the country of origin, requires constant feeding of the plant with balanced fertilizers. If feeding is not observed, the hydrangea does not bloom.
The flower bush is very picky about the type of soil. If the soil is not acidic and low in iron, Hydrangea not only does not bloom, but also loses the green color of the foliage.
Despite the fact that hydrangea is resistant to many diseases, it is not immune to damage from mites, aphids, and weevils, which also negatively affects the flowering of the plant.
A fully developed Hydrangea bush blooms for four to five years during the so-called juvenile period. If the hydrangea has ceased to please with its bright inflorescences, it needs a transplant.

Domestic Hydrangea and the main factors for lack of flowering

Growing flower bushes indoors requires a little more attention. This is due to the fact that it needs to be provided with the same growth conditions as outside. Consequently, if not properly cared for, indoor hydrangea may bloom late or not form inflorescences at all.

Magnificent hydrangeas in the house do not bloom if:

chosen for the pot bad place in terms of lighting, flower shrubs love the sun, but direct exposure to ultraviolet radiation should not be allowed;
Regularity and moderation of watering is not observed;
not supported favorable temperature regime+18-22°C and air humidity 75-80% in the room where the flower grows;
pruning was performed incorrectly before preparing the plant for wintering.

These are, perhaps, all the whims that should be taken into account when propagating hydrangeas in your garden. personal plot and in the house. Moreover, it should be noted that there is no difference in the requirements of the shrubby and tree-like Hydrangea species.
Now it’s clear why hydrangea doesn’t bloom. How to achieve the opposite effect and create favorable conditions for its wild flowering.

Proper plant care at home and in the garden

Knowing what to do in the absence of air hydrangea flowers, it is easier to help it bloom in all its glory. Long-blooming Hydrangea can be grown:

and in the flowerbed,
and in the shady garden;
and on window sills in flower pots.

Caring for hydrangea in the garden and in the house has some differences. If you cannot grow a shrub fragrant with inflorescences, then following the tips below, you can still achieve what you want in one season.

In order to admire the long-awaited flowering of the magnificent hydrangea, the plant should be planted correctly. To do this, first of all, you need to decide where it will grow: in room conditions or street.

Planting in a flowerbed

There are some nuances.

They are as follows:

It is recommended to plant hydrangea seedlings in the ground either in late autumn or early spring before buds appear on the trees.
The flower shrub takes root best in partial shade and moderately lit areas.
The recess for planting should not exceed 50 cm in diameter and 50 cm in depth. For full development The root system of the plant has enough such parameters.
It is advisable to plant hydrangea in loamy soils enriched with peat.
When planting a perennial bush, its roots are pruned; when planting young seedlings, this procedure is not required.
In the prepared hole, a small hill is formed from the prepared soil, on which the prepared seedling is placed and the roots are straightened so that they fall down. Next, the soil is compacted and watered.
If Hydrangea is planted in late autumn, then you need to hide the soil under the bush under mulch. This is done in order to provide favorable conditions for the plant to overwinter.

If hydrangea seedlings are purchased, grown in a greenhouse and planted in the spring, the plants should be supported during the period of adaptation to natural conditions, namely, to provide watering, protection from drafts, and fertilize the soil for one and a half months with special complex factory-produced fertilizers.

Planting in a pot

Planting a hydrangea seedling in a pot is carried out in compliance with the following conditions.

Indoor hydrangea prefers turf, leaf soil and sand in a ratio of 3/3/1.
If, when growing a shrub on the street, it is possible to provide the root system with freedom, then the roots of horizontal branching in the usual flower pot feel constrained. Therefore, when growing hydrangea at home, preference should be given to containers with a wide bottom.
Drainage is placed at the bottom of the pot (crushed stone, expanded clay, pebbles, brick chips). The second layer is the prepared soil from which the hill is formed. A seedling with neatly straightened roots is placed on it. Next, the pot is filled with the remaining soil, but it is important not to fill the root collar - leave it at the level of the last soil layer.
The final touch when planting hydrangeas in a pot is watering and laying a layer of peat mulch to prevent rapid evaporation of moisture.

At home, you can plant not only a hydrangea seedling in a pot, but also sow the seeds:

For sowing, humus, turf and leaf soil should be used in a ratio of 1/1/1.
To plant hydrangeas using the seed method, choose a low container with a wide bottom.
Sowing is done at the end of winter. Its peculiarity is the absence of seed placement in the soil.
The container with seeds on the top layer of soil is covered with film and placed in a warm, bright place.
Before shoots appear, the seeds are ventilated and moderately moistened with a spray bottle.
After two leaves appear on the shoots, they are picked and planted in separate pots.

Trimming

Both flowerbed and indoor Hydrangea require pruning.

It happens like this:

In late spring (late April - early May) it is necessary to remove non-viable and weak shoots, while in late autumn only dry inflorescences are cut off.
When pruning, you should be aware that inflorescences appear only on last year's shoots.

Fertilizer

Proper feeding of hydrangea consists of observing the dosage and time of application of fertilizers.

Flowerbed hydrangea will produce large inflorescences if it is fertilized with nitrogenous fertilizers in the spring:

A solution of urea and potassium sulfate. For ten liters of water, dilute one tbsp. spoon of fertilizer. The need for one fully developed bush is five liters of solution.
Slurry diluted in water in a ratio of 1/10. Watering is carried out within a week.
A weak solution of potassium permanganate, which is used to water the plants and spray the crowns of the bushes.

Also abundant flowering Hydrangea growth can be achieved by adding potassium and phosphorus mineral supplements to the soil during the formation of inflorescences.
To ensure long flowering in the summer, flower bed hydrangea is fertilized potash fertilizers, which also allow the plant to retain moisture. In addition, in the summer it is recommended to oxidize the soil with curdled milk or cheese.

During the autumn period, hydrangeas need potassium-phosphorus fertilizers.

When the shrub is preparing for winter dormancy, to ensure its frost resistance and endurance, potassium sulfate and superphosphate are added to the soil in a proportion of one tbsp. spoon per ten liters of water.
Indoor hydrangea should be fed throughout the summer. No more than twice a week you need to water the flower with a solution of mineral fertilizers, containing water (one bucket), superphosphate (40g), ammonium nitrate (30g), potassium sulfate (30g).

Preparing for winter

Outdoor Hydrangea blooms profusely if its wintering has been properly organized.
After pruning and fertilizing, flowerbed hydrangea bushes are tied with twine.
The roots are covered with leaves, spruce branches and coniferous branches. The mulch layer should be at least 10 cm.
In regions with harsh climatic conditions, hydrangea bushes are additionally covered with film.
Preparing potted hydrangea for wintering involves:

removal of dry inflorescences and leaves;
placing the pots in a dark, cool place (+8-10°C);
minimal soil irrigation.

Watering

Potted hydrangea is demanding when it comes to watering. Moisture should be moderate so that the roots do not rot or become sick. You need to water the flower with settled water. room temperature. Watering is carried out only when upper layer The soil dries out well. Additives to water for irrigation citric acid or vinegar cause abundant flowering.

Flowerbed hydrangea requires more moisture, so water it regularly twice a week when it’s hot and once if it rains during the week. One adult hydrangea bush requires from 30 to 50 liters of warm, settled water.

Variety selection

Hydrangea may not bloom due to the whimsical nature of the variety. Not all types of flower bushes, even with careful care, quickly adapt to a new climate. Sometimes from planting a seedling to the moment of flowering, it takes from five to seven years.

When choosing a hydrangea variety, you should study its care requirements. For example, paniculata (Hydrangea paniculata, Unique, Kyushu, Grandiflora, Brussels Lace, Limelight) and tree hydrangea (Annabelle, Hydrangea arborescens) take root in cool regions, while large-leaved hydrangea (Hydrangea acrophyla, Blauer Zwerg, Gerda Steiniger, Ever Peppermint, Endless Summer) and oakleaf (Hayes Starburst, Incrediball, White Dome) are more suitable for a temperate climate.

The heir to the Far Eastern natural species and selection novelties of the European collection, Hydrangea, as this flower is called in botanical atlases, is represented in domestic floriculture by several varieties resistant to cool summers and harsh winters:

There are no evergreen forms among them. Sometimes, for wintering, certain varieties have to be transplanted into pots and brought indoors, but minus temperature up to 10◦C, and even -25◦C, some of the hydrangeas (for example, paniculata) can withstand reliable temperatures.

All parts of the growing hydrangea are considered poisonous because they contain cyanogenic glycoids, but folk medicine root extract is used as a tonic, wound healing, diuretic and analgesic.

Necessary conditions for flowering

Among gardeners, there are two opinions on cultivating hydrangea: unpretentious plant, and - quite capricious. They are based on correct and incorrect choice landing spots.

After all, growth inhibition, poor flowering, chlorosis or powdery mildew are a consequence of unsuccessful placement of the bush, or choice of soil composition. The plant may also suffer from an excess of gardener love: excessively flooded or “fed” with fertilizers.

Optimal conditions for growth:

Well-lit hill above the horizon groundwater, where there is no direct sun, but partial shade forms.
Natural or artificial protection from constant winds and rainfall.
Podzolic soils and nutritious loams; acidity is not higher than pH4.5-5.
Constant moisture of the earthen coma.
Temperature background is not lower than +12◦С.
Regular removal of weeds and shoots from the root circle.
Formative pruning.
Proper preparation for wintering.

IMPORTANT: In areas with alkaline soil, artificial acidifiers are used for the well-being of the bush: citric or oxalic acid (30 ml per bucket of water), and even battery electrolyte (1 ml per liter of water).

The ability to influence color is a rare gift of nature to man.

The beauty of the spherical inflorescences of hydrangea is provided by sterile four-petal flowers bordering inconspicuous small fertile ones. The latter produce a seed pod and are honey plants, but the moth-like sterile flowers are admired.

At the very beginning of flowering, regardless of the variety, they all have a light green color. Only over time does it become obvious what color the panicles will be.

The palette of blooming hydrangea: from chaste white and pale beige through all shades of pink to delicate tones of lilac, blue and blue. It's hard to believe but The color of the inflorescences is determined by the acidity and content of chemical elements in the soil:

the presence of Al or Fe in the form of alum guarantees all shades of blue;
on slightly alkaline soils, sterile flowers will have a pink (natural) color;
The addition of peat also contributes to the color change.

ATTENTION: Harmless ones are commercially available chemical compositions, capable of changing the color of inflorescences, with greater or lesser intensity depending on the amount of added substance.

This treatment is carried out at the beginning of the growing season. Regular use of additives gives unambiguous color of panicles, irregular use results in two-colored appearance.

Special hybrids of hydrangeas have been developed that can change color and are very easily “repainted” into the desired color - “NikkoBlue”, “Blaumeise”, etc. The snow-white varieties are the most difficult to change color; at best, their inflorescences can acquire a slightly pink tint. By influencing color samples, you can get complex shades of red and blue - lilac, violet.

People have discovered this feature of influencing the color of hydrangea inflorescences experimentally a long time ago: they buried rusty objects in the bush or watered the plant rusty water.

How to prolong the joy of admiring?

A flowering bush pleases the eye for several months; inflorescences cut for a bouquet stand in water for 2 weeks. But the desire to extend the flowering season prompted florists to preserve blooming hydrangeas different ways for up to a year. This is drying:

Such a flower will last in a floral arrangement for a year without losing color, but then it will still fade.

You need to cut flowers for drying at the end of the season., when fertile flowers begin to actively bloom, and sterile ones begin to change color and fade. It is very difficult to catch this moment: if you hurry, the flowers will dry for a very long time to the detriment of their beauty; if you are late, they will turn from colored to brown. Plucking faded flowers is also not recommended, as this can cause the entire panicle to wither.

IMPORTANT: Hydrangea does not tolerate drought, but excess moisture is also harmful to it. It causes fungal diseases and can rot the roots. A weakened plant is a home for aphids, mites and nematodes.

Why doesn’t it bloom in the garden and what should be done in such cases?

This is perhaps the most important disappointment of the gardener. Well, in the first year - of course, it’s too early for her. And then? The reason may be:

an incorrectly selected variety for a given region;
artificial stimulation of a pre-sale copy, as can be seen from the emerging buds;
a sharp change in the substrate in which the purchased plant was located and the garden soil;
lack of development of the root system;
early release of the bush from frost protection in spring;
frost damage to the upper buds;
improper pruning of stems, with the removal of flower buds;
constant plant stay in the shade;
lack of a fertilizer complex.

Correctly identifying the causes will help to correctly eliminate them, and wait for the solemn moment: the lush flowering of the hydrangea bush.

Hydrangea is a shrub of magnificent beauty. In gardening, it is valued for its variety of inflorescence shapes, varied color palette, and very simple care. Often, it turns out that a person buys secondhand blooming hydrangea, replants it, but the inflorescences gradually begin to fade, and over time it dries out completely. So, why doesn't hydrangea bloom? In this article we will try to understand this issue.

Description

Hydrangea belongs to the Hydrangeaceae family, which contains about 70-80 plant species. Most species are shrubs 1-3 m high, some species are small trees, the rest are lianas. Most plants are deciduous. Hydrangeas bloom from spring to late autumn. The flowers are collected at the end of the stem into beautiful large inflorescences.

The shape of the inflorescences can be:

Oval;
Ball-shaped;
In the form of a panicle;
In the form of a cone.

Inflorescence color:

White;
Blue;
Pink;
Lilac;
Crimson;
Red;
Lilac;
Cream.

There are varieties that simultaneously combine several colors in color. The acidity of the soil directly affects the color of the inflorescences.

Hydrangea fruit – 2-5 – separate capsule with numerous small seeds.

The homeland of this shrub is North America, East and South Asia.

Varieties

Enough is known a large number of types of hydrangeas are shrubs, trees and vines. More and more often they can be found on garden plots in Russia. The most common are:

Hydrangea paniculata;
Hydrangea large-leaved (or garden);
Hydrangea;
Hydrangea petiolate (climbing);
Hydrangea oakleaf;
Hydrangea radiata;
Ash hydrangea (gray);
Hydrangea serrata;
Hortensia Sargent.

In addition to the above species, there are others, but they are rarely seen in our gardens.

For indoor growing One type of hydrangea is used - this is Hydrangea macrophylla. This species was brought over 200 years ago from China. This plant blooms from spring to late autumn.

Reasons for lack of flowering

Many who grow this plant often wonder why hydrangea does not bloom?

There are actually a lot of reasons:

Improper pruning of shrubs in spring.
Insufficient watering.
Not developed root system.
Use of a growth stimulator.
Poorly lit place.
Freezing of the plant in winter.

Hydrangea flowering can be easily restored. You just need to follow all the rules of care, including remembering to periodically apply fertilizer.

Rules for planting and care

Hydrangea is a light-loving plant. But bright Sun rays And strong wind she could be harmed. Grows well in shady places. Hydrangea loves fertile, acidic, loose soil.

Landing rules:

Planting should be done in the spring, when the soil has warmed up and the threat of night frosts has passed.
Before planting, the plant must be pruned and the roots shortened.
The hole for planting should be spacious 50*50 or 80*80 cm, which depends on the size of the plant.
The soil must be fertilized - add organic and mineral fertilizers.
The planted bush should be watered abundantly and covered with fallen leaves. For watering, it is better to defend the water, which saves the plant from leaf chlorosis. Watering is best done in the morning and evening, when there is no hot sun.
Some species and varieties must be pruned annually when buds appear to prevent the bushes from becoming too elongated.

Even a beginner in gardening can quickly learn how to care for this plant. You just need to water it in a timely manner, loosen the soil and prepare the plant for wintering. You also need to know the amount of fertilizer application. If their number is too large, then too voluminous inflorescences will form, and under their weight the branches may simply break.

Reproduction

Hydrangea propagation is carried out in the following ways:

By layering;
Seeds;
Cuttings.

The most effective and the easy way Propagation of hydrangea by cuttings is considered.

Diseases and pests

The main diseases that affect this luxurious plant:

Chlorosis, in which yellowness appears on the leaves.

Gray rot leading to the appearance of brown rotten spots on the leaves.

Septoria blight, which causes brown spots to appear on leaves with a diameter of about 5 mm. In this case, the infected leaf darkens over time and completely disappears.

Rust, which is characterized by a rusty color on the leaves.

But in addition to diseases, hydrangea can be plagued by various pests and insects:

Aphid. It can be found on the back of the leaves. A flower affected by this pest grows very poorly.

Spider mite. It will not be possible to detect this pest special labor, since the branches are covered with cobwebs.

Slugs. They eat leaves.

To prevent and control pests and insects, the soil should be treated with various chemicals: insecticides, antifungal drugs, pesticides, folk remedies.

Use in landscaping, combination with other plants

Hydrangea is at the peak of popularity today. It is used to create different floral ensembles and garden styles.

With the help of hydrangea, unique compositions are created in the garden. It can be used in pairs with lilac, spirea and mock orange. You can also combine this plant with others garden flowers, which have a similar shape. This creates an amazing effect during the flowering period.

If hydrangea is planted near a pond, then it can be combined with plants that love moist soil, for example, hosta, astilbe, and bergenia.

Medicinal properties and uses

Hydrangea can be more than just a garden decoration. Since ancient times, the Cherokee Indians have used hydrangea root for kidney problems.

It has the following medicinal properties:

Calming;
Diuretic;
Prevents kidney stone formation;
Painkillers;
Bactericidal.

Hydrangea is used to treat:

Sore throats. Flowers and leaves are used. 1/10 tbsp. Pour boiling water over the mixture and bring to a boil. Leave for 1 hour, then strain. Take 100 ml 3 times a day warm 30 minutes before meals.

Diarrhea. Fresh crushed leaves are used. 2 tsp leaves per 1 cup of boiling water. Leave for about an hour, then strain. Take 2 tbsp. 3 times a day before meals.

Cystitis. Fresh leaves or branches are used. Preparation: pour crushed leaves or branches with alcohol in a 1:1 ratio. Let it brew. Take ½ tsp. 2 times a day.

Hydrangea is very beautiful and unpretentious flower. Its lace caps decorate any garden, bringing special tenderness and comfort to the area. You can plant hydrangea bushes in flower beds, along a fence, or use them as a hedge. And although hydrangea has a fairly unpretentious nature, not all gardeners can achieve its flowering.

In order for a flower to be beautiful and give lush color, it must be properly cared for, properly watered, pruned and fertilized. Why doesn't hydrangea bloom, but only produce foliage? Let's look at the possible reasons.

Why doesn't hydrangea bloom, but only produce foliage?

Weak root system - it will be like this if it is not properly cared for or if the seedling is less than two years old. Some varieties (and there are about 70 of them in total) do not bloom at all in the first 6 years after planting.

The planting site is chosen incorrectly - hydrangea loves slight partial shade or diffused natural light. It is possible that the flower will grow and bloom normally in the sun, but in most cases direct sunlight is harmful to it. It is also not recommended to plant bushes under tree crowns, near a roof slope or a house.

Something is wrong with watering - in hot and dry weather it should be done at least twice a week, rain or settled water will do. One-time watering of a bush should take a bucket and a half of water, no less.

Poor soil characteristics - hydrangea will bloom only if the soil in which it grows is loose, fertilized and well-moistened. For most varieties, it should be slightly acidic - with alkaline and neutral ones there will be much less chance of waiting for flowering (measure the acidity of the soil and change it if necessary - this can be done by watering with a sulfuric acid solution).

Improper fertilization - applying nitrogen fertilizers stimulates foliage growth, and fertilizing with potassium and phosphorus affects the abundance of flowering. Nitrogenous compounds need to be applied, but only in spring and summer, the bushes need other feeding, otherwise they will not bloom.
Excessive pruning of bushes - if you cut off all the branches for the winter, the plant will next year will not bloom. Autumn pruning involves removing dry branches that have no leaves, thin and weak shoots, branches growing towards the stem - leave the rest
The buds are frozen or the branches break off - to prevent this from happening, place stones or bricks under the branches, another option is to close the plant for the winter.

It is impossible to say for sure why your hydrangea bush is not blooming, so check all the possible factors mentioned above. Something must definitely help!

One of the beautiful flowers that decorate the garden is hydrangea. But despite easy care, some gardeners wonder why paniculate hydrangea does not bloom.

To help hydrangea bloom and prolong flowering, you need to find out what is the reason for the lack of flowering.

Agrotechnical conditions for hydrangea growth

Hydrangea paniculata is a shrub, up to 3 meters high, with upright spreading branches. Small flowers are collected in large pyramidal inflorescences, 20-30 cm long. Flowering is abundant from June to October (depending on the variety). The color of the inflorescences varies from white to pink, lilac, and blue. Some varieties can change the colors of the inflorescences with changing weather conditions.

The main conditions for the successful development, growth and flowering of a plant are:

It is possible to make a large-leaved variety of paniculata hydrangea bloom or accelerate growth only if you follow the recommendations for planting and proper, high-quality care.

Reasons for lack of flowering

This type of hydrangea reacts sharply to insufficient (improper) care, which is noticeable when the plant’s foliage grows excessively, the flower becomes very small in size, while it becomes sparser, less lush, and the color of the inflorescences becomes faded.

The main reasons for the lack of flowers in paniculate hydrangea are the following.

Improper watering

For successful growth and flowering, the plant needs regular watering. In hot weather, water should be 2 times a week, in dry, cool weather - 1 time a week.

Watering is carried out with clean, settled water at the root, at least 10 liters of water for each hydrangea bush.

Note! It is important to monitor the root system and drying of the earthen coma. Excess moisture has a detrimental effect on flowering.

Fertilizer application

If fertilizers of inappropriate compositions are not applied in a timely manner, the plant experiences severe stress, which negatively affects external condition hydrangeas. It is necessary to apply fertilizing according to the schedule recommended by experienced gardeners:

During planting, in early spring and before flowering, mineral (containing phosphorus, potassium, magnesium, zinc) and nitrogen-containing fertilizers are applied weekly under the roots. You can mulch the root zone organic fertilizers(household plant waste, mown grass, sunflower tops, etc.).
In the summer (during budding or the beginning of flowering), potassium-phosphorus fertilizers are applied once every 7-10 days, and nitrogen fertilizing is stopped.
IN autumn period(after flowering) apply phosphorus fertilizers to strengthen and better winter hardiness of the buds. You can add rotted cow dung.

Hydrangea will grow, bloom and decorate the garden with its color only on fertile, loose, well-moistened and fertilized soil. If the acidity of the soil is insufficient, you can add a little wood ash (experienced gardeners They recommend grapevine ash, fruit trees: cherry, peach, apple).

Wrong landing site

Planting hydrangea paniculata in a shaded place or under the scorching rays of the sun in a draft is fraught with dropping leaves, lack of flowers, or flowering with very small sparse inflorescences.

Planting hydrangea

The best place to plant hydrangea is an area in partial shade or with diffused sunlight, protected from drafts, sharp gusts of wind, with fertile soil and sufficient water supply. Planting in lowlands with constant stagnation of water contributes to rotting of the root system, its underdevelopment, lack of growth and flowering.

Planted in the shade of fruit trees paniculata hydrangea will not bloom, even if you increase watering and fertilizing.

Incorrect autumn pruning

If pruned incorrectly when forming the crown, the shrub stops blooming. Proper pruning consists of shortening weak and thin shoots. Only dry branches and shoots that grow inside the crown and thicken the bush can be completely pruned.

Trimming the top shoots, on which buds form in the fall, is strictly prohibited, because from these buds in the spring buds will awaken, which will open into a luxurious flower.

Insufficient shelter in winter

Despite the fact that paniculata hydrangea is the most frost-resistant variety, when growing this species in northern regions Russia needs shelter for shoots in winter.

Shelter is carried out after autumn pruning with the onset of cold weather, when all the inflorescences have already faded. The hydrangea flower bush is tilted to the ground, covered with agrofibre (lutrasil) and covered with peat or earth. You can use fallen dry leaves and spruce needles.

Important! Under no circumstances should you use plastic film for covering to prevent the greenhouse effect and rotting of the root system of the shrub.

Branches of an adult bush (over 5 years old) should be bent to the ground with extreme caution so as not to break them.

The cover should be removed in the spring, when the threat of frost has completely passed. You should not trim branches that seem dry at first glance, as they sufficient watering buds may appear on them, which over time will turn into a luxurious flower.

Adaptation after landing

After planting a hydrangea bush, it is important to pay due attention to the development of the plant. During the first time after planting, it is necessary to frequently water only the planted bush in order to speed up the process of rooting and development. Also add fertilizing and growth stimulants. The first time after planting, the leaf may become more faded and lighter. But as the hydrangea's growth takes root, the leaf will become brighter and stronger.

You should also refrain from purchasing and planting hydrangeas grown in greenhouse conditions. Since in this case it was carried out drip irrigation, a large amount of fertilizers and growth stimulants were added to the soil, which will negatively affect flowering in the years following planting.

Planting hydrangea

Poor development of the root system

Hydrangea blooms in the second year after planting, when its root system is sufficiently formed. Young bushes, overfed with fertilizers, weak underdeveloped roots are the reason for the lack of flowering.

If you do not make the above mistakes, this will help the plant to overwinter and delight its owner with lush flowers.

Lack of flowering for several years is another problem that novice gardeners face. The main reasons for this problem are abnormal development (underdevelopment) of the root system, excessive feeding, excessive watering, and severe freezing of shoots.

Reasons for late flowering

If paniculata hydrangea begins to bloom late, then the reasons may be:

¾ Planting the plant in unsuitable, infertile soil with high acidity, heavy, loamy, sandy soil.
¾ Lack of nutrients. The lack of fertilizing and fertilizers manifests itself in the form of late flowering of the bush, regardless of the variety and early ripening.
¾ Excess moisture.
¾ Damage to fungal infections (powdery mildew, late blight),
¾ Pest damage: weevils, aphids, spider mites.

On a note! You can speed up flowering using fertilizers. It is recommended to apply complex fertilizers that are suitable for the composition and variety of the plant. Positively proven fertilizers are: Agricola, Kristalon (Fertika), Pokon, Green Boom, Flower Paradise.

At home, you can make hydrangea bloom earlier in the following ways:

ü Reduce the amount of watering, and then increase sharply. Such changes will provoke an artificial onset of flowering.
ü Lightly prune the youngest shoots to speed up the growing season and make the hydrangea bloom earlier.
ü Thoroughly loosen the soil, mulch it with organic matter, feed it with yogurt (stir 3 liters of fresh yogurt in 10 liters of water and water the roots generously).

To avoid frequently asked questions what to do when hydrangea paniculata does not bloom (blooms late), it is important to strictly observe agrotechnological measures that contribute to the rapid development of the root system, timely and abundant flowering.

Variety selection

When choosing a type of paniculata hydrangea for planting, it is important to pay Special attention variety, compliance of the plant climatic zone, planting and care requirements.

A variety bred for cultivation in the southern regions of Russia, when planted in the northern regions, will either bloom late or not bloom at all.

Proper and proper care helps to grow healthy plant, and the accelerated growth of the root system contributes to abundant and lush flowering, regardless of the variety and color of hydrangea.
