It is worth recognizing that hydrangea is one of the most beautiful and long-flowering perennials, which comes in the form of a shrub or a small tree. Depending on the variety, it has very beautiful inflorescences of various shapes and can also change color during its flowering.
But it often happens that the hydrangea stops blooming or the flowering becomes not so abundant and bright. Why this is happening, and what needs to be done so that the hydrangea begins to bloom again magnificently and brightly - this will be discussed below.
Why hydrangea does not bloom: reasons and what to do, how to properly care for it to make it bloom
Most often, hydrangea does not bloom due to the fact that it was originally planted incorrectly or grooming not according to the rules: they do not feed on time, often violate the irrigation regime, pruning is carried out incorrectly, they forget or incorrectly cover for the winter. Sometimes pests attack this flowering shrub or it is affected by fungal diseases. As a result, the perennial weakens and blooms poorly or stops flowering altogether.
To prevent this from happening with hydrangeas in the garden, you need to remember about the main agrotechnical measures, on the accuracy of which the abundant flowering of these shrubs depends.
The time has not come
The main mistake of many novice flower growers is as follows - they expect hydrangea to bloom almost immediately after planting seedlings in open ground. But you need to understand that these flowering shrubs.. during the season they will only take root and grow roots. By autumn, most varieties will only have flower buds that will bloom only in the next season after planting. If there were seedlings, then they can bloom already on next year.
Therefore, you should not panic if, after planting, your hydrangea does not begin to bloom - it just has not yet come for this. It is also possible that the flowering period will move another season or two if the planting or care conditions are not met.
Worth knowing! Most often, hydrangea begins to bloom only at 3 or 4 years old, and from 5 years old - abundantly. Therefore, as a rule, 3-4-year-old seedlings are sold.
Planting not according to the rules: wrong choice of place, soil or wrong planting of a seedling
The place for planting these flowering perennials should be sufficiently well lit in the morning or evening hours, but not the bright afternoon sunbeams, which can burn the delicate foliage of hydrangeas. Very light partial shade is also suitable for these shrubs.
In general, it is believed that treelike and paniculate Hydrangeas bloom best when there is morning or evening sun, so they are best planted in light shade. Besides, too open space the shrub will fade very quickly, and it will have to be watered more often, because hydrangeas, in principle, are moisture-loving.
Important! How more sun, so better flowering, but if there is too much of it, then the flowering will be short-lived. Accordingly, in the shade, the plant will bloom longer, but not abundantly, so you need to find the optimal balance.
Another thing, large-leaved hydrangea ... This is truly a partial shade plant, in such conditions it will bloom very well.
It is worth understanding! Despite the fact that hydrangea is considered a shade plant, it will bloom profusely only if good lighting in the morning (before lunchtime) or in the evening (from 5-6 hours until sunset).
It is equally important that the area where hydrangeas are grown is well protected from east and north winds that can simply break all your beautiful flowers.
Advice! The ideal place in the garden for planting hydrangeas would be an area near a fence or garden house.
But it is not worth planting under trees, since they will create a shadow (sometimes excessive), and also take most of the necessary moisture, therefore, the plant will not receive the required nutrition and will not bloom.
Hydrangea does not bloom well in the shade
Hydrangea is also demanding on the composition of the soil, namely, on the degree of its acidity (required 4.5-5 pH). Although most varieties grow well on slightly acidic or neutral soils (for example, tree hydrangea), but here in alkaline soils, these perennials begin to hurt, do not bloom and die as a result.
Therefore, it is imperative properly prepare the landing pit for planting hydrangeas, or rather to do acidic substrate to fill it (holes). For this, sour horse (or brown) peat, rotted sawdust is suitable. coniferous trees, coniferous litter or pine bark (you can collect all this in the forest).
Important! In no case in the substrate can not be added dolomite flour, lime or wood ash(for example, as a potash fertilizer), because all these are deoxidizers (reduce acidity), but we need, on the contrary, acidifiers (increase).
Optimal size planting pit for young and small 1-2 year old hydrangea seedlings - 30 by 30 cm, for older and large 3-4 year olds - 50 by 50 cm.
Note! Learn more about when (terms) and how to properly plant hydrangeas in your garden, you can from the following articles and.
Difficulties in adaptation: the shrub does not take root in any way
Often after planting purchased hydrangea seedlings on permanent place v open ground they adapt for a long time in a new area or even begin to hurt, which means that there can be no talk of any flowering. The main reasons may be as follows:
- Previous owners (if they gave it to you or bought it at the garden center) added to the soil too much fertilizer so that the plant grows faster. And in a new place you filled the landing pit with fairly poor soil(they forgot to add phosphorus-potassium fertilizers), so the hydrangea does not grow in any way and, accordingly, does not bloom.
Advice! In order to fill the planting pit, 30 grams of potassium fertilizer (for example, potassium sulfate) and 60 grams of phosphorus (superphosphate) must be added to the substrate.
- The same happens if you transplant hydrangea from initially acidic soil to slightly acidic(especially if it is a seedling with an open root system).
- If the purchased seedling with a closed root system, then when it is planted in a permanent place you can not shake off the earthen lump, especially prune the root system.
Advice! Actually, always it is preferable to buy seedlings in containers (with a closed root system).
Lack of moisture or waterlogging
The correct watering regime for the plant is also very important. Hydrangea is that flower that drinks a lot of water and always drinks, which means that for abundant flowering he needs a constantly moist soil. But it is also impossible to pour it, the bush can rot. However, in this particular case, it is better to pour over than not to top up.
If the soil under the bushes is too dry, then the plant is also sluggish. What a bloom here! Therefore, in the summer, hydrangeas need to be watered at least 2 times a week. And it is better every other day or even every day if the heat is above +30. Also, for better moisture retention, it is recommended to mulch the soil next to the bushes.
Note! If your soil is clayey, therefore, moisture will stagnate in it, so you must definitely do good drainage at the bottom of the landing pit during disembarkation.
Wrong choice and untimely fertilization, excess or lack of fertilizing
Excess fertilizer in the soil is also harmful to this. flowering perennial as well as their lack. Especially it is dangerous to use nitrogen fertilizers in the second half of summer and even more so in autumn in a large volume, because nitrogen contributes to the growth of vegetative mass to the detriment of flowering. And if such feeding is introduced into autumn period, then new shoots begin to actively grow in the bush, which do not have time to sufficiently develop and mature before the onset of frost. As a result, they simply freeze out and die in winter. In addition, the growth of shoots in autumn leads to the fact that nutrients are spent by the plant not for preparing for winter, but for growing shoots, which significantly weakens the hydrangea, and as a result, the plant may freeze in winter.
Therefore, fertilizers, predominantly containing nitrogen, are applied to the soil under hydrangeas only in spring, and in the summer and autumn, top dressing should consist for the most part (a little nitrogen is still allowed) of phosphorus and potash fertilizers... Such fertilizers activate the appearance of inflorescences (promote budding) and excellent flowering, and in autumn they help shrubs to lay flower buds and better prepare for the onset of cold weather.
Thus, for example, if you realized that you have overfed the hydrangea with nitrogen, then you should fertilize it with an increased amount of potassium-phosphorus fertilizers, but within reasonable limits.
Fertilization should be started in early spring, when the buds on the shoots are just beginning to swell.
Note! It is advisable to dissolve each of the fertilizers in water (all doses are written for 10 liters of water and 1 square meter of the flower bed) and water at the root.
There are also special ready-made fertilizers for hydrangeas.
Advice! If you rarely visit the country, then it is optimal to use special complex fertilizers prolonged action... In other words, in early spring, 1 time you need to close up the fertilizer in trunk circle hydrangeas, and the plant will gradually receive nutrition throughout most of the season.
Soil acidification is not carried out
Note! The need for fertilizing, as well as acidification, arises about 2-3 years after planting, when the plant completely pulls out of the substrate with which it was filled landing pit, all juices (all meals).
If you want hydrangeas to bloom luxuriously and not suffer from chlorosis, then the soil under the hydrangeas should always be acidic, which means that it must be acidified periodically (at least once a month during the flowering period).
You can acidify the soil under hydrangeas with the following compositions and solutions:
- a weakly acidic electrolyte solution (10 ml per 10 liters of water);
- vinegar (100 ml of 9% vinegar per 10 liters of water);
- citric acid (20-40 g per 10 l of water).
Advice! Moreover, it is desirable to additionally add iron chelate or (20-30 grams per 10 liters) to the above solutions.
You can regulate the color of hydrangeas by changing the acidity of the soil. So, the more acidic the soil, the more violet or blue the color will be, and, conversely, if the acidity is lower, then the inflorescences can be pink or crimson.
Worth knowing! Making blue hydrangeas out of pink is not so easy. Even if you have very acidic soil, but it lacks movable aluminum, then color changes will not follow. Therefore, you need a solution of potassium alum (30-40 grams per 10 liters, consumption for adult plant- up to 2-3 liters), or you can use aluminum sulfate (dig into the soil, up to 500 grams per 1 square meter).
Incorrect pruning in spring and / or autumn
No trimming, for example, actually you cannot achieve a chic and friendly flowering of a tree hydrangea that blooms only on shoots current year... Therefore, it can be argued that pruning directly affects flowering. But it should be understood that this does not apply to all hydrangeas. That is why it is very important to know the characteristics of your particular species and variety, because other species bloom on last year's shoots, and if you cut them every year, then the hydrangea simply cannot bloom.
Important! Often, inexperienced growers remove flower buds. In this case, the hydrangea will not bloom next year. Therefore, most often, although the essence of pruning does not change.
In addition, some types and varieties of hydrangeas form too many shoots, in this case, excess branches growing inside the bushes must be removed so that the bushes do not thicken. If timely do not thin out the bushes, then the inflorescences will be smaller, and on strongly thickened perennials, flowers may not appear at all.
It is equally important to periodically (every 4-5 years) carry out anti-aging pruning, because inflorescences will not appear on very old branches.

Lack of shelter for the winter
It is necessary to shelter hydrangeas for the winter in most regions of our country. This is done so that the flower buds do not freeze - in this case, the perennial will not bloom next year. However, not all types of hydrangeas need shelter. So, the tree-like and paniculate varieties are quite frost-resistant, but they should also be slightly spud or mulched, while the large-leaved one must be covered for the winter.
Before the onset of cold weather, all shoots are tied together and covered non-woven fabric... Or you can simply cover the stems from above with coniferous spruce branches, which will well protect the plants from temperature extremes. However, it is still better to install the frame on top and place the covering material on it.
Important! About, what hydrangeas and how to properly cover them for the winter, read in detail.

Diseases and pests
Most often, the hydrangea is not sick with anything, and it is rarely overcome by any pests. In addition, she can quite successfully resist such attacks on her own. But if the plant nevertheless got sick with something, and because of this its flowering stopped, then you need to urgently help it.
For example, hydrangea most often has chlorosis, which manifests itself in the fact that the leaf plates begin to fade, become light bile in color, spots appear on them, and they begin to fall off, and the flower ovaries become smaller. This is due to the alkalization of the soil and the lack of iron in it. To defeat the disease, an increased amount of iron and an acidifier must be added to the soil for its normal and rapid absorption. For this, a solution or iron chelate is suitable, as well as one of the acidifiers (sulfuric acid, vinegar or citric acid). For example, in a bucket of water, mix 20-40 grams citric acid and 20-30 grams of ferrous sulfate.
Fungal diseases"Attack" hydrangeas very rarely and only when the soil is too wet. Therefore, to prevent them, the irrigation regime should be observed so that the soil is moist, but without stagnation of moisture in it. However, it happens that on the leaves of the hydrangea you may notice powdery mildew ... Treatment with a solution will help to cope with it or
Of the pests most often on hydrangeas, the following can appear:
- slugs and snails;
- spider mite;
But for strong and sturdy shrubs, attacks of such pests are not terrible. They can usually be dealt with folk methods: by spraying with soap or onion infusion. Or you can use insecticides such as Fitoverm, Fufanon, or Actellik.
Thus, in conclusion, I would like to note that all varieties of hydrangeas are distinguished by long and abundant flowering, if these shrubs are properly looked after and initially planted according to all recommendations. However, it should be admitted that these flowers can hardly be called unpretentious, since if the irrigation regime is violated, improper feeding, lack of acidification, incorrect pruning, these perennial shrubs can stop flowering. But observing all the rules for caring for these perennials, there is no doubt that hydrangeas will thank their owners with abundant and lush flowering.

Hydrangeas or garden hydrangeas are amazingly beautiful and lush-flowering plants that look very impressive on summer cottages, flower beds. These beauties can reach a height of 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-type flowers, and larger and brighter male flowers, which consist of four or five enlarged sepals, adorn the edges. In addition, this plant can be not only a shrub, but also a small tree, and even a liana. The possibilities for designing a plot with hydrangea are endless!
Usually the hydrangea bloom period lasts from late spring to early autumn. But sometimes gardeners who planted this plant a few years ago do not wait for the inflorescences to appear. It happens that hydrangea blooms poorly, and why is unknown.
Reasons for the lack of flowering
Before looking for reasons explaining why the garden hydrangea does not bloom, and deciding what to do, you need to know about some of the characteristics of the species. So, tree and panicle hydrangeas are very demanding on the conditions of detention. In addition, young plants will not form inflorescences until they gain strength, but this lasts for years. More interesting: It is difficult to say exactly in what year after planting the hydrangea blooms, because the quality of the soil, and the level of lighting, and the regularity of watering matter.
In most cases, this plant does not bloom due to the fact that it root system not yet sufficiently developed. If you bought a flowering bush, planted it on the site, and the flowering gradually faded away, do not be surprised. Unscrupulous sellers often use growth stimulants to make the hydrangea bloom. As a rule, for another two years after such a forced flowering, the plants do not release inflorescences, gaining strength.
The second reason is the wrong pruning of plants. Older varieties of large-leaved garden hydrangeas produce inflorescences at the top of the shoots that have grown in the past year. If you are not worried about sheltering the bush from frost for the winter and preparing it for winter, then these shoots will have to be removed due to freezing. More interesting: It is quite natural that during the flowering season your hydrangea will not please with lush inflorescences. Moreover, it will not bloom for the next several years.
Shoot pruning should be done at the end of October. At the same time, several pairs of young buds are left on the shoots. In the spring, these young shoots are shortened again so that the flowering is more lush.
The laying of the buds of the garden hydrangea occurs in the fall. If frost hits at the beginning of spring, when they begin to wake up, they will freeze. How many hydrangea blooms It is not recommended to remove the shelter from the bush until the air temperature at night settles at -5 and above degrees.
The birthplace of hydrangeas is middle Asia where the climate is different from the domestic one. When buying a plant in stores, pay attention to varieties that are well acclimatized for our natural conditions... The fact is that the thermophilic hydrangea may simply not have time to lay new flower buds during our short summer, therefore it will not bloom next year.
Providing garden hydrangeas with proper care, you will acquire an excellent decoration in the garden, and fragrant lush inflorescences will delight the eye. long time... Let your hydrangea bloom as much as you like!
Hydrangea or hydrangea (Hydrangea) belongs to the class of Hortensia. Under natural conditions of growth, it can be found in countries East Asia, North and South America as well as in the Himalayas. It is very beautiful ornamental plant with a specific feature. Its original inflorescences in those species that have a white or cream color, with the onset of autumn, acquire a red, burgundy, raspberry or cherry color. Also, their shade depends on the composition of the soil. If you enrich the soil in the area where the flowers are planted with aluminum sulfate, they will turn blue or light blue. And if you water the plants with a solution of potassium permanganate, then the inflorescences will turn pink.
Despite the fact that hydrangea is the favorite of most gardeners for its beautiful and long flowering, it is a rather capricious plant. At the same time, different species have their own rules of care, non-observance of which leads to the absence of buds. This article answers the question: “Why does not it bloom garden hydrangea».
Reasons for the lack of flowering garden hydrangea
There are many reasons for the lack of flowering of garden hydrangea. They can be both general and individual for each species. Therefore, before planting this beautiful flower you need to study its features and rules for caring for it.
Unsuccessful seedling planting site
Since the garden hydrangea is perennial shrub, who does not like transplants, then the place for her planting should be chosen in accordance with her preferences. Otherwise, the plant will not develop well, and flowering may be absent. The main rules for choosing a planting site for a garden hydrangea can be considered as follows:
Hydrangea does not like transplants
- The site should be located so that in the first half of the day it was as illuminated as possible. After lunch, the plants should be in partial shade. If this is not possible, then you need to create additional shading for the hydrangea before flowering in the afternoon. Plants planted in a place that is too sunny can get sunburn and those that grow in constant shade bloom weakly.
- Plants must be protected from winds and drafts that inhibit their development. The best place would be planting near a house, gazebo or other garden buildings.
- It is not recommended to plant the hydrangea near other large shrubs or trees. It is quite hygrophilous, and other plants will actively absorb water, which can lead to a lack of moisture.
- Hydrangea has a shallow root system. Therefore, if it is part of flower arrangements, it is desirable that its neighbors were flowers, the roots of which grow deeper. Otherwise, they will not allow the plant's root system to fully develop.
Hydrangea is demanding on the composition of the soil
The composition of the soil is of great importance for garden hydrangea; it must 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 of moisture
Hydrangea is very moisture-loving plant, therefore, watering for it has essential... It should be carried out weekly, pouring 20 liters of water under each adult bush. If the weather is too hot, then watering is carried out twice a week.
The water must be soft, because tough negatively affects the condition of the plant. Tap water let it stand for at least five days before watering.
Lack of moisture can lead to wilting of foliage and dropping of buds. Prolonged drought leads to the death of the hydrangea. But you shouldn't overflow the soil, you need to let the top layer dry out. Otherwise, rotting of the root system and the development of various diseases may occur.
Adaptation after disembarkation
Planting a garden hydrangea in open ground is best done in early autumn. In this case, during the winter, the plant has time to root well and get used to a new place of growth. Since hydrangea does not tolerate a transplant, in order for it to quickly take root, several rules should be followed:
Planting hydrangeas is best in early autumn.
- When removing the plant from the container, a clod of earth should be preserved 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 make additional shelter for the plant.
- The soil should always be slightly damp, but without overflow.
If new leaves appeared on the hydrangea within a month, it means that the adaptation was successful. In the future, it is important to properly prepare young plants for wintering in order to preserve them until spring.
Hydrangea, planted in the fall, usually blooms the next summer and is more resistant to disease and pest infestation. Those plants that are planted in spring bloom only for 2-3 years of growth, since the first summer they spend on adaptation.
How the root system should develop
Hydrangea is distinguished by a widely branched root system, which must be taken into account when planting.
Hydrangea has a superficial, widely branched root system. Therefore, it is desirable that the rest of the 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 ground part.
Incorrectly selected fertilizers
Garden hydrangea is prized primarily for its vibrant, lush and long-lasting flowering that can only be achieved correct feeding... Also, additional nutrition is required because the bushes of the plant grow quite large. Therefore, they quickly absorb useful material from the soil.
Top dressing begins in the spring, using complex mineral fertilizers every two weeks. They can be alternated with organic matter, such as slurry. To do this, the manure is diluted with water in a ratio of 100 grams per 10 liters of water. This will ensure the full growth of green mass.
With the onset of flowering, nutrient complexes are used that do not contain nitrogen, for example, superphosphate. This is required in order for the active development of buds to occur, and not foliage. An excess of nitrogen in the soil does not allow young shoots to stiffen, and during wintering they may die.
Fertilization is carried out weekly. This is necessary for the formation of new flower buds... Once a month, you can water the hydrangea with sour milk drinks (kefir, yogurt, and others).
With the beginning of autumn, fertilization should be stopped so that the plant can calmly enter the dormant period. In September, ash can be added to the soil at the rate of 100 grams per one square meter... It is also recommended to add 15 kilograms of manure under each bush. This will be an additional top dressing in the spring and will protect the root system during the winter.
Frozen kidneys in winter
Hydrangea blooms on last year's shoots, on which flower buds are laid during summer and autumn. Therefore, if they freeze in winter, then the plant will not bloom. In this regard, it is important correct preparation hydrangeas for wintering. First of all, you need to prune in accordance with the type of plant, and then cover it in accordance with the following recommendations:
Frozen buds may be the reason for the lack of flowering.
- Low bushes are completely covered with peat and tightened with covering material.
- Around the young tall plants stacking heavy boards and hammering nails into them. Then the bushes are rewound with ropes, carefully bent down and fastened to the nails. After that, they are covered with sawdust, 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 do not bend so as not to harm the plants. They are simply completely wrapped with covering material and tied with rope. A metal mesh is installed around the bushes, dry foliage is poured inside, and the outside is covered with plastic wrap.
Shelter should be removed after the end spring frosts as they can also damage the kidneys.
Unsuccessful shrub pruning
Unsuccessful shrub pruning can completely stop flowering
Hydrangea pruning must be done correctly. If flower buds are removed during it, the plant will not bloom. In the first two years of growth, it is not recommended to do it at all. Each type has its own terms and methods for pruning the bushes.
How to properly prune and prepare for wintering
When pruning your garden hydrangea, consider the following guidelines:
- Large-leaved hydrangea is pruned at the beginning of the autumn period at the end of flowering. In this case, only the removal of inflorescences, remaining buds and dried stems occurs. Pruning of shoots in the fall does not occur; it is done in the spring after the buds open, so as not to harm the flowering.
- Treelike 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 removed completely. Because given view prone to thickening, then the crown of the bushes is formed at this time. For this, extra branches are cut out, usually located inside the plants. You also need to remove any remaining inflorescences.
- The panicle and oak-leaved hydrangea are pruned in the spring. In the autumn, only inflorescences and buds are removed.
- Petiolate hydrangea dramatically pruned in the spring and, if necessary, in the summer. This is done to form a beautiful crown due to the formation of additional lateral shoots. In the autumn, only the removal of inflorescences, weakened and dried stems is carried out. Also, in the fall, lateral shoots are slightly shortened.
In order for the hydrangea to winter comfortably, after the pruning has been carried out, the plants are covered to protect them from frost.
Diseases and pests
With proper care, hydrangeas form strong bushes that are rarely infested with diseases and pests. If the rules for keeping the plants are not followed, they are affected by the following diseases:
Subject to agricultural technology, hydrangea is rarely affected by pests and diseases.
- Powdery mildew. When it occurs, the foliage is covered gray bloom that darkens over time. Then the leaves begin to wither and fall off, and the shoots are 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 up.
- Chlorosis. The foliage begins to discolor, curl and fall off. At the same time, the veins remain bright green color... Buds and flowers are deformed, change color and crumble.
If signs of these diseases are noticed on hydrangeas, you need to immediately start treatment. To do this, remove all affected leaves and parts of the shoots. After that, treat the plants with a fungicide solution and shed the soil with it, since the root system can also be damaged.
Hydrangea pests can be dangerous spider mites, scale insects, aphids. If they are found on the plant, it should be washed with a solution of green or laundry soap... After that, spray with an infusion of onions, garlic, tobacco or wormwood. If the data folk remedies do not help, you need to treat the hydrangea with an insecticide solution.
Incorrectly selected variety
When choosing a hydrangea variety, you need to take into account climatic features.
Hydrangea has species and varieties with varying degrees of frost resistance. Therefore, when choosing a plant, one should take into account the climatic conditions of the area. In regions with a warm climate, you can breed different kinds... For northern latitudes, frost-resistant plants are suitable, for example, numerous varieties of tree hydrangea. Heat-loving species will freeze out without proper care.
Reasons for the lack of flowering in species and varieties
Since all types and varieties of plants (tree, 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 the lack of flowering are the same for them. The only difference is the rules for pruning.
Reasons why a garden hydrangea has not bloomed for several years
Don't worry if your planted garden hydrangea hasn't bloomed for several years. The fact is that often the first flowering occurs only after 2-3 years of growth. Some varieties of panicle hydrangea bloom only in the 6th year of cultivation. If, nevertheless, after this time, flowering has not occurred, then the conditions for the growth of the plant and the rules for caring for it need to be revised.
Reasons why hydrangea does not bloom in indoor conditions
Indoor hydrangea, grown in compliance with all care rules, is also characterized by abundant and long flowering. The reason for his absence may be an incorrectly spent rest period. Therefore, when growing hydrangeas in indoor conditions the following recommendations should be observed:
- In autumn, at the end of flowering, you need to remove all inflorescences and dried shoots.
- Send the pot with the plant to a darkened 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, the plants are placed in normal growing conditions.
Hydrangeas, for which the above conditions of rest are met, will have a 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... However, 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 on flower beds, lawns, hedges are created. With the help of varieties of petioled hydrangea make original decor for gazebos and walls. At the same time, it does not require large physical and time costs for its care, the main thing is to know what to do if the hydrangea does not bloom.
WITH correct pruning you can get acquainted with hydrangeas in the proposed video clip. Happy viewing!
Hydrangea is especially popular among amateur flower growers. This is due to a number of factors. First of all, hydrangea flowers gather in inflorescences and form large "caps". And the colors range from pale white to bright red or purple.
Such a plant will decorate any flower bed. A feature of hydrangea is that you can grow it at home. However, she is quite whimsical and sometimes it is difficult to answer the question of why hydrangea does not bloom. How should you care for this plant so that it is pleasing to the eye during flowering? Hydrangea can be grown both outdoors and in a pot. Let's consider each case separately.
Garden hydrangea
This shrub does not tolerate the sun well. Therefore, when choosing a place for planting, it is necessary to choose a shaded area, on which direct sunlight practically does not fall. It is constantly necessary to ensure that the soil is moist. Hydrangea, with a lack of moisture, not only blooms poorly, but also slows down the growth rate. A prerequisite for hydrangea flowering is the presence of an acidic soil.
Fertilization and care
Like any other shrub, hydrangea needs fertilization, feeding and pruning. It is advisable to feed the flower several times a month with special substances.
Pruning
As for pruning, the situation here is somewhat more complicated than with feeding and fertilization. Pruning is done:
- in the spring, if during the winter the branches of the bush have suffered from cold weather;
- in the fall, to rejuvenate the plant.
To avoid damage to the branches, you need to cut off all the inflorescences every fall. An exception is the macrophile, which does not need pruning. Such a need exists only when there are branches affected by frost. At the same time, care must be taken not to remove branches with flower buds during pruning. This is often the reason why hydrangea does not bloom.
Care features
You also need to ensure that the soil is loose. If you want to avoid the constant work of loosening the soil, you can add mulch. And it is advisable to water the plant with warm water. Hydrangea can hardly be called a frost-resistant plant. Therefore, for the winter it needs to be covered or dug up.
Reasons for the absence of inflorescences
Based on the foregoing, the answer to the question of why the garden hydrangea does not bloom may be as follows:
- wrong landing site;
- incorrect trimming;
- damage to shoots by frost;
- insufficiently developed root system.
Due to the fact that there are more than 80 types of hydrangea, each of them has specific features... Consider possible reasons lack of inflorescences for the most popular varieties.
Panicle hydrangea

Making a hydrangea bloom is easy
Why the hydrangea does not bloom, we figured it out, but what needs to be done so that this plant begins to delight with lush inflorescences? You can try to find a better place. However, when transplanting, the plant may suffer. Therefore, you need to dig out the hydrangea carefully so as not to damage the root system. Otherwise, it will not bloom until it recovers. And this can take about two years.
It will also be helpful to increase the acidity of the soil. This can be done with coniferous humus or peat. In no case should you use chalk, ash or lime for feeding. These substances reduce the acidity of the soil, and therefore, will cause the lack of flowering.
One of the main enemies of hydrangea is frost. Therefore, for the winter, the plant must be wrapped up and the soil must be mulched. Damage to flower buds from residual frost will answer the question of why hydrangea does not bloom.

After winter, you will need to get rid of the affected branches, and from the flower buds you will get lush "caps" of inflorescences.
Another reason for the lack of flowers can be pests. These include mosaic leaf disease, downy mildew, gray mold, aphids, weevils, weevils, and spider mites. If you find signs of the disease, then you need to immediately take measures to combat them.

Finally, I would like to say a few words about one feature of this wonderful shrub. Hydrangea can change its color. In order for the plant to change color, aluminum alum can be used. In a previously prepared container, you need to put 5 grams of these alum and pour 1 liter of water. If there are several plants, you need to do large quantity solution. However, the ratio of water to aluminum alum should remain the same. It remains to water the soil with the resulting liquid. And the color change occurs due to a change in the acidity of the soil and the amount of iron in it. If you have iron filings at hand, then you can safely replace alum with them. As a last resort, old nails will do.
You can show your imagination and feed the bush only on one side. The result is a hydrangea with inflorescences. different shades... Obviously, miracles do not happen and bright red flowers will not work out of white flowers. However, you can pink color turn into rich lilac, and white into pale blue.
