Hydrangea is mainly a plant for gardeners. But there are also varieties that can be grown quite successfully at home. The most suitable species for this is large-leaved hydrangea. It is a very beautiful variety with oval dark green succulent foliage. The greatest advantage is flowers. They come in pink, red and white... But in order to wait for them, you need to know the rules of content and navigate when the problem "why hydrangea does not bloom".
Blooming home hydrangea
Which is provided proper care, is able to delight its owner with abundant flowering for a long time. This plant can bloom for a good six months during the period from mid-spring to mid-autumn. The basic rules, adhering to which the hydrangea at home will actively grow and bloom:
- You must choose right place for a pot with hydrangea. You need to choose a place that is well lit, however, without direct sunlight. Indoor hydrangea can feel good even in partial shade. This moment is especially important during the warm season. In the winter months, you can safely place the flower on the sunniest windowsill.
- Insufficient and untimely watering. This flower is very hygrophilous. The soil under it must be constantly moist. It is also necessary to spray the flower quite often. After the plant sheds some of the leaves before wintering, watering can be carried out less often.
- The plant is too hot. Hydrangea cannot stand the heat. It is advisable to keep the flower at a temperature not exceeding 20 degrees Celsius.
- The plant needs correct pruning... It must be remembered that hydrangeas are capable of blooming two-year shoots. Pruning should be carried out until mid-summer and cut in half the shoots on which the flowers have already faded. Only a few of the strongest shoots should remain until the dormant period. Pruning may also be needed when spring arrives. Again, you need to cut off weak shoots so that they do not take away the strength necessary for flowering.
- Violation of the rest period. The rest period should last two to two and a half months. At this time, the plant must either be sent to a cool basement and kept at a temperature of about 7 degrees Celsius, or vice versa, move it closer to the light. It is impossible to completely stop watering, but you need to completely abandon fertilizing. Breeders have also developed varieties that can be left under normal room conditions and they do not shed their leaves as hard as the common hydrangea, which is a deciduous plant. It should also be borne in mind that if you realized late that your pet still needs a cool winter, then you can not suddenly take it out into the cold after a while in the conditions heating season... It must be gradually adapted to lower temperatures by gradually increasing the time spent in a cool room. The systematic absence of a dormant period in hydrangea negatively affects not only flowering, but can also significantly reduce the life of this plant.
- The plant does not like the acidity of the soil. Hydrangea does not like slightly acidic soil. Periodic acidification is recommended using lemon juice in proportions of 5-6 drops for 1 liter of water. Use of ash, lime, chalk and dolomite flour - undesirable.
- The plant lacks nutrients. It should also be borne in mind that the hydrangea must be transplanted annually. If, after flowering, the plant is not transplanted, then this may next year become the reason why hydrangea does not bloom. Fertilizers must not be forgotten either. The flower especially needs feeding during the period of bud formation and flowering itself.
Flowering garden hydrangea
With regard to why the hydrangea, which grows in the open field, does not bloom, then the answer depends largely on what kind of garden hydrangea is in question.
- The most common reason why pink hydrangea does not bloom is that the plant is frozen over. It is necessary to take care of a comfortable stay outside the bush in the cold season. It must be covered for the winter. Also, frost, in addition to freezing the buds, can lead to discoloration of foliage.
- Treelike hydrangea also needs to be protected from frost. During the rest of the year, it is important not to forget that all varieties of hydrangeas are extremely hygrophilous.
- In panicle hydrangea, flowering may never occur if it is planted in sandy soil... Also, a feature of this variety of hydrangeas is that it loves a soil with low acidity.
Also, all varieties of hellish hydrangea and room must be protected from pests and. Get in trouble, stem nematode.

Luxury hats blooming hydrangea can often be seen in our gardens. Domestic types of hydrangeas are also grown. Sometimes the owner of the bush, expecting a violent flowering from the plant, discovers that it does not come, but only leaves grow. Let's try to figure out what is the reason and how we can fix the situation.
Why garden hydrangea does not bloom
We plant a garden hydrangea so that it delights us with its luxurious bunches of inflorescences
If the garden hydrangea does not bloom, then among the main reasons may be the following:
- landing site,
- freezing of flower buds,
- unsuccessful trimming,
- wrong soil composition,
- lack of moisture
- incorrectly selected fertilizers.
Landing place
Hydrangeas like to receive morning or evening sun rays more, but not less than 6 hours.
Freezing of flower buds
Large-leaved hydrangea blooms on last year's shoots, flower buds it is laid in the fall. If the buds freeze in late autumn or early spring, then it is useless to wait for them to bloom.
Incorrect cropping
Different types of hydrangeas require different pruning.
For the same reason, flowering may not occur if the hydrangea is incorrectly pruned in the fall or spring.
They begin to cut and form hydrangeas only from the third year of life. Prior to this, pruning of the shrub should not be carried out.
Incorrect soil composition
If a hydrangea bush is planted in an improperly prepared soil composition, you can not wait for flowering either. The thing is that hydrangeas need acidic soil (4.5–5 pH). If the composition is alkaline, the plant will not only not bloom, but will wither and die.
To acidify the hydrangea soil, you can add citric acid in the proportion of 1.5-2 tbsp. without a slice for 10 liters. water. Or you can do it easier: collect rotted coniferous litter in a coniferous forest and sprinkle it under a hydrangea bush.
You can acidify the soil for hydrangeas with citric acid.
Lack of moisture
Hydrangea is one of those plants that require abundant watering. Watering the hydrangea bushes should be at least twice a week, or even more often, especially if the weather is hot. It is better to mulch the soil around the bush to retain moisture.
Insufficient feeding
A hungry hydrangea can also refuse to bloom.
For flowering hydrangeas, you need to feed well.
Problem solving methods
The very first condition is to determine what kind of hydrangea you are growing. Many of the features of care will depend on this. There are several main varieties of the plant: paniculate, treelike and large-leaved.

In hydrangea, paniculate inflorescences have an elongated shape. panicle-like 
Tree hydrangea is the most hardy and unpretentious 
Large-leaved hydrangea can change the color of inflorescences
Landing place
It is better to plant a hydrangea not in a sunny place, but in a light shade, on the east or west side of the site, so that the bush is protected from the midday sun by a shade.
Freezing of the kidneys
To prevent this from happening, large-leaved hydrangea must be covered for the winter.... To do this, you can first wrap the bush with lutrasil or spunbond, and cover it with dry leaves on top, having previously built a wire frame around the bush. Some varieties of this species need to be dug up for the winter and stored in the basement.
The wire frame will help to reliably cover the large-leaved hydrangea from frost
The other two species - treelike and panicle hydrangeas - are frost-hardy enough, they can do without shelter, it will be enough to mulch with peat, fallen leaves.

Pruning
Have large-leaved hydrangea pruning is advised to be carried out in the spring, while trimming only dry inflorescences is necessary, because flower buds are found at the ends of last year's shoots.
Large-leaved hydrangea should be trimmed carefully, removing only dried last year's inflorescences
Tree-like and panicle hydrangea you need to cut harder, because it blooms on the shoots current year... This can be done both in the fall and in early spring... The pruning scheme is as follows: each shoot of this year is cut into 2–4 buds if the branch is growing strongly, and by 1/3 if the shoot is weak.
These species will benefit from the correct thinning of the bush, it contributes to the intensity of flowering. Dead shoots can be cut back to old wood. Shoots growing inside the bush are also removed.
Treelike and panicle hydrangeas should be cut short enough

Conducting dressings
Usually, three hydrangeas are fed during the season. In order for the hydrangea to bloom, at the very beginning of growth, complex fertilizers are applied or fertilizers are combined with organic matter. To obtain profuse flowering, phosphorus and potassium are needed. You can use superphosphate or any other complex fertilizer containing these ingredients. The dosage is 1 tablespoon per 10 liters of water.
During the budding period, hydrangeas require potassium-phosphorus feeding
Why indoor hydrangea does not bloom
Indoors, winter gardens, greenhouses most often grow large-leaved hydrangea.
Home hydrangea loves a bright place and moist air.
If the home hydrangea also refuses to bloom, there may be several reasons:
- plant age,
- lack of lighting,
- problems with the composition of the soil or its moisture,
- a sharp change in temperature.
The clod of earth should be moist, and the plant itself must be periodically sprayed from a spray bottle if the air in the room is dry. It is desirable that the water is well settled.
A sharp drop in room temperature can lead to dropping of buds.
Often summer residents ask why doesn't hydrangea bloom?
To answer this question, you must first figure out which of its varieties grows in your garden. Despite the fact that many articles have been written about hydrangeas, there is still confusion on this issue.
And if you can determine which hydrangea grows with you, then you will know what to expect from it.
First of all, I want to say that there are several types of garden hydrangeas that successfully grow in middle lane... They differ from each other in the shape of the inflorescence, color and, most importantly, in their winter hardiness.
Treelike and panicle hydrangeas
Hydrangea
The most famous and most winter-hardy are treelike and panicle hydrangeas. The inflorescences of these varieties are mostly white, but now breeders have created many varieties with pink flowers.
These types of hydrangeas bloom every year, because their flowering does not depend on how well the plant overwintered. They bloom on young shoots, that is, those that have grown in the new season.
Hydrangea paniculata
Treelike and panicle hydrangeas are pruned at the end of the season, resulting in more powerful shoots and large inflorescences the next year.
Large-leaved hydrangea
Large-leaved hydrangea is a hydrangea with pink and blue flowers... Her fundamental difference from paniculate and tree-like is that it blooms on the shoots of the last year, and its flower buds are located at the ends of these shoots.
And this is what happens - if the large-leaved hydrangea was cut off or it froze in winter, then there will be no flowering.
I want to draw your attention to the fact that varieties of large-leaved hydrangea have different winter hardiness. There are some of them that do not hibernate at all in the open field, even with good shelter. They are grown as houseplants... Such hydrangeas are sold in the spring with bright and large inflorescences.
At the same time, there are varieties of large-leaved hydrangea that hibernate with shelter. In spring, as a rule, 
sold still small and without flowers.
Be careful when buying hydrangeas, as not all consultants are competent enough in this matter.
What if the large-leaved hydrangea does not bloom?
- Cover the hydrangea in time - before the onset of frost. She is usually covered earlier than roses. In the spring, do not rush to remove the shelter, do it only when the frost is over.
- Do not prune large-leaved hydrangeas as they bloom on last year's shoots. Do not shorten the ends of the shoots, even if they do not fit under the winter shelter, there are flower buds at the ends.
- Pull hydrangea bushes carefully. Try to bend the branches to the ground so that they are covered with snow in winter. Even if the bush itself winters well, and the flower buds at the tops of the shoots freeze, then there will be no flowering.
- If the hydrangea still has not bloomed, then continue to care for it. In order for the shoots to ripen better, feed it with a special fertilizer for hydrangeas.
If you do everything right, the hydrangea will bloom next year.
In our time, breeders have created varieties of large-leaved hydrangea that bloom twice a summer - first on old shoots, and then on the shoots of the current year. It is best to choose them, since if a bush of this kind freezes in winter, it will still bloom on new shoots, but closer to the month of August.
Hydrangea varieties that bloom twice a season - “Endless Summer”, “You and Me”, “Together Forever”.
I wish you success in all your endeavors, dear friends!
- a beautiful, but capricious flower that does not always meet the expectations of gardeners, and does not always bloom in response to careful care. What is the reason for this phenomenon, why indoor or garden hydrangea refuses to bloom, and what to do in order to rectify the situation? There are many answers to these questions, let's look at them together.
The right choice when buying
When buying a room or garden hydrangea, you should pay attention to whether there are buds on the stems. If the answer is yes, then the sellers watered the hydrangea with flowering stimulants, forcing it to bloom to give it a “presentation”. Young plant has already spent a lot of effort on the formation of buds, and after transplantation it may not bloom for two years, or it will not take root at all in a new place. What to do in this case? Transplant the bush to another pot or open ground together with a clod of earth so that it adapts better in a new place. And after a period of adaptation, start feeding him mineral fertilizers.
To answer the question: why hydrangea does not bloom, you need to know what type of plant you are buying. Some types of hydrangea at a young age cannot bloom, or bloom poorly, because they have not yet accumulated enough nutrients for the beautiful and lush bloom... After all, the inflorescences of most hydrangeas are large, the bush spends a lot of energy on them.
Such types of hydrangeas, such as garden large-leaved, tree-like and paniculate hydrangeas, do not immediately bloom. The first 1-2 years after planting they spend on the development of the root system, then the aerial part is strengthened, if both stages the plant has passed successfully, it will begin to bloom only in the third year.
And yet - for planting in open ground, choose zoned hydrangea varieties. If the summer in your area is too short, flower buds will not have time to form and there will be no flowering.
Effect of pruning on flowering
Improper pruning is another factor that has a significant impact on the flowering of a garden or indoor hydrangea. In order not to ask the question: why the hydrangea does not bloom, it is necessary to cut it correctly. Moreover, the concept of "correct" for each type of hydrangea individually.
So, in the spring, in the fall, only faded inflorescences are cut off so that they do not break under the weight of the snow. If the hydrangea did not bloom in the summer, then it is not necessary to cut it at all.
In the spring, the panicle hydrangea is pruned before budding, if you miss the pruning time, the development of the plant will be suspended so much that it will not bloom this season. When pruning, remove weak and small shoots, as well as shoots frozen in severe frosts. Annual shoots are cut so that 3-4 pairs of buds remain on them.
Large-leaved hydrangea blooms only on the shoots of last year, or rather, on young branches that grew on last year's shoots. And if you remove last year's shoots when pruning, there will be no flowering. Pruning large-leaved hydrangea is carried out only to remove damaged stems and last year's inflorescences.
Groundcover hydrangea blooms on young shoots this year. Pruning it consists in shortening too long young branches, due to which the bush becomes more branched and blooms more profusely.
From this we can conclude: in order for the hydrangea to bloom, its pruning is carried out taking into account its species features, otherwise you may never see her bloom at all. Do not forget that the hydrangea growing in wildlife, blooms without any pruning, therefore, at home, you should not get too carried away with this operation.
Correct wintering
To protect the hydrangea from severe frosts, they begin to prepare it for winter in the fall. In areas with a warm climate, it will be enough to cut off the inflorescences and wrap the bush with agrofibre, and where the temperature in winter drops below 25 degrees, it is necessary to make a more reliable shelter.
Old inflorescences are cut off, the branches are bent to the ground and covered with peat, earth or sawdust. To do this, the bush is fenced with boards to make a box - branches are laid in it. In order not to bend them too much, first dry grass or leaves are placed on the ground, and branches are laid on this pillow. From above, the box is also nailed down with boards, after a heavy snowfall, it is additionally insulated with snow.
In the spring, with the onset of heat, the entire structure is removed, the plant is rejuvenated by pruning. When spring frosts, which are so frequent in Russia, the bush needs to be covered with agrofibre - if the flower buds, which have just begun to develop, freeze, the plant will not bloom this year.
The whims of a home flower
Sometimes indoor hydrangea growing in favorable conditions... What is the reason, and what to do in this case? Let's start from afar - in the fall, indoor hydrangea can completely shed its leaves and retire. At this time, it is taken out into a dark, cool room, watering is reduced, carrying out them only so that the roots do not dry out and with the beginning of spring the plant begins to grow and bloom again.
At the end of winter indoor hydrangea taken out in a bright and warm room, they begin to water and feed well. At the same time, you should not put the flower pot in the direct rays of the sun - the hydrangea prefers coolness and diffused light. If the temperature in the room is too high, they try to create a special conditions - remove it away from the window and heating appliances, often ventilate the room without exposing the flower to drafts. Hydrangea does not like sudden changes in temperature; this feature must also be taken into account.
Soon, new shoots will begin to grow from the roots, on which inflorescences are formed. If there are too many shoots, some of them are removed, leaving 3-4 of the strongest and largest. The remaining stems are fed with mineral fertilizers. Good fertilizer for hydrangea, it is a sleeping coffee, which is scattered over the soil surface in a pot.
Every 3-4 years, the hydrangea is transplanted to a new place, for this they make a soil mixture with an acid reaction from peat, needles, leaf and sod land. You can use ready-made soil for azaleas by adding some needles to it.
