- It is necessary to study his preferences, determine the need for watering and lighting.
- In this case, it is necessary to take into account the characteristics of the soil, the place of planting and the plant variety.
- If you carefully analyze the conditions in which the hydrangea grows, you can find the reasons for its trouble and correct the mistakes made.
The main reasons for the lack of flowering and their solution
- Bad place to plant a seedling
- Too little or too much moisture
- Adaptation after disembarkation
- Incorrectly selected fertilizers
- Kidneys frozen in winter
- Failed shrub pruning
- Diseases and pests
- Wrong variety selected
Bad place to plant a seedling
Hydrangea feels uncomfortable in open places, being under the scorching rays of the sun all day. The tender leaves of many varieties in the heat sag lifelessly and burn.
In a sunny place, the plant will be saved by an underestimated landing. The trunk circle of the bush should be 10 cm below ground level. It must be mulched with coarse-fiber peat or sawdust to the surface of the earth. Under such conditions, the plant can develop and bloom normally.
In hot and sunny regions, it is better to grow panicle hydrangea. With regular moisture, it will withstand direct sunlight all daylight hours without compromising flowering.
In deep shade, under the crowns of large trees, hydrangea is unlikely to please with a lush color. The perennial does not develop well with strong shading, regardless of which variety is planted. If flowers appear, they will be sparse and underdeveloped.
All varieties of plants prefer places where the sun's rays fall only before lunch. In such conditions, hydrangea blooms especially brightly, magnificently and for a long time.
If the place for the shrub is chosen unsuccessfully and it is not possible to correct the situation, you need to transplant it. This should be done only as a last resort, since the plant does not tolerate transplantation well. The most suitable time for transplantation is autumn. At this time, the perennial is at rest.
- Having picked up a suitable site, you need to dig a hole to a depth of 50 cm. The extracted soil is mixed with 2 buckets of humus and 80 g of mineral fertilizer are added.
- Hydrangea loves acidic soil and grows quickly in it. Therefore, the soil for it must be acidified with a solution of sulfuric acid (1 tsp per 10 liters of water).
- It is necessary to replant the plant very carefully, along with a clod of earth.
- If during transplantation damage root system, the plant will not bloom for a long time.
Too little or too much moisture
Moisture is the main feature of hydrangea. The shrub has the botanical name Hydrangea. Translated from Greek, "hydrangea" means "vessel of water." With a lack of moisture, the plant stops flowering. Its roots must always be kept moist. Do not allow the earthen coma to dry out near the roots. If the weather is dry, the hydrangea may die without watering.
In cool weather, it is enough to water the flower once a week. On hot and dry days, watering should be done every 3 days. A young plant also needs additional moisture until it is 1 year old.
If the soil is clayey, water less frequently. Water will stagnate in heavy soil. With an excess of moisture, hydrangea can reduce or stop flowering. An abundance of water leads to rotting of the roots and death of the plant. Heavier than others, the accumulation of moisture near the roots of the oak-leaved hydrangea tolerates. It only needs well-drained soil. To prevent water from accumulating in clay soil, pine bark must be added to it.
- For irrigation, it is better to use rain or filtered water.
- Tap water must be defended before watering for 5 days.
- For a single watering of the bush, you need 1-1.5 buckets of water.
- To prevent moisture from spreading, it is worth making an earthen side at the base of the bush.
In the garden, among large and powerful hydrangea trees, moisture will not be enough. Tree roots will take water from the flower. Even if the roots of the trees are removed when planting a perennial, they will grow in a year.
Adaptation after disembarkation
Very often after planting a healthy flowering plant in open ground, it loses its decorative qualities and stops flowering. A sharp deterioration in the condition of the flower is due to the lack of the usual dressings.
Sellers of hydrangeas often abuse fertilizers and overfeed plants, achieving lush flowering and rapid growth. Getting into natural conditions, a flowering bush begins to hurt.
He is not able to independently absorb the necessary substances from the soil. Such a plant may die if emergency measures are not taken.
- When transplanting hydrangeas from a container into the soil, you do not need to cut the roots and shake off the substrate.
- It will be very difficult for a weakened plant to restore the root system.
- The soil remaining in the container must be mixed with garden soil and poured into the root zone.
In the first year, you need to regularly feed hydrangeas, gradually reducing the dosage. It is important to create a plant ideal conditions in the first months after transplantation, preventing drying and stagnation of water in the root zone. When the hydrangea gets stronger, it will begin to develop and bloom.

Incorrectly selected fertilizers.
Hydrangea does not respond well to excess fertilizer in the soil. It is especially harmful to apply nitrogen fertilizers to the soil in summer and early autumn.
They are used to enhance the growth of green mass and do not contribute to flowering. BUT fast growth shoots in the fall leads to the fact that they do not have time to ripen for the cold and freeze.
Proper feeding of the plant is carried out several times a season.
- At the end of spring, nitrogen fertilizers are applied to enhance the growing season.
- In summer, fertilizing with potassium-phosphorus fertilizers is used to stimulate and maintain flowering.
- In early September, potassium-phosphorus preparations are applied to strengthen the shoots and prepare for winter.
- in early spring- from the moment the sap flow begins, for the development and growth of new strong shoots. The mixture for the first feeding can be prepared independently by mixing potassium, urea and superphosphate in equal proportions. The optimal dose of application is 60 g under one bush. You can also dilute another solution - one tablespoon of sodium sulfate and urea per bucket of water, the consumption will be 5-6 liters per plant;
- early summer (June)- at the stage of formation of ovaries to increase the number of buds. Before flowering, experienced flower growers are advised to feed the hydrangea with a mixture of Agricola and nitrophoska, 1 tbsp each. for 10 liters of liquid. It will not be superfluous to apply green fertilizer - one bucket of diluted nettle infusion per adult bush with further watering;
- mid summer season- during the period of active blooming of inflorescences for long-term flowering. In the phase of active flowering, special complex mineral fertilizers are used, but in smaller quantities and concentrations. From the end of July, nitrogen should be excluded from the composition of nutrient dressings in order to exclude unfavorable overwintering of shrubs; It's important to know: top dressing should be applied every two weeks, otherwise the flowering will be frail and not abundant. along with mineral fertilizers, hydrangea responds well during this period to adding organic matter - chicken manure or dung slurry;
- autumn (October)- to prepare the plant for wintering and laying young shoots and peduncles. At the end of flowering, it is more useful to fertilize hydrangea with humus or peat - pour substrates 10-15 cm high into the near-trunk zone of each plant. Feeding in the autumn with phosphorus-potassium fertilizers will have a beneficial effect on a plant sleeping in winter.
With the help of top dressing, you can change the color of the spherical flowers of the shrub. Blue shades will give a solution of water and alum (ammonia or potassium), and lime will increase the pink tones.

Kidneys frozen in winter
To protect the hydrangea from severe frosts, in the fall they begin to prepare it for winter. 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 drops below 25 degrees in winter, it is necessary to make a more reliable shelter.
Hydrangea shelter for the winter.
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, dry grass or leaves are first placed on the ground, and branches are laid on this pillow. From above, the box is also boarded up 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. In the case of spring frosts, which are so frequent in Russia, the bush must be covered with agrofiber - if the flower buds that have just begun to develop freeze slightly, the plant will not bloom this year.

Failed shrub pruning
If the buds of future flowers are removed during autumn pruning, the plant will not bloom in due time.
Pruning hydrangeas should be done only when necessary. Young plants should not be touched until they begin to bloom. The first flowers appear on the perennial in 2-3 years. Panicled hydrangeas can bloom only for 6 years.
In autumn, most varieties of hydrangeas can be left uncut. Spring pruning is best done at a later date, when frost damage to the shrub is visible. Remove dead buds, shoots and broken branches.
- From correct pruning depends on the decorativeness of the shrub.
- Some types of hydrangea have a very developed shoot-forming ability.
- If you do not thin out the bush, it will quickly thicken and will bloom less abundantly with small inflorescences.
- On a heavily neglected perennial, flowers may not form.
- It is necessary to cut small branches inside the bush that do not give full-fledged inflorescences.
To enhance flowering, last year's shoots must be shortened, leaving 1-3 strong pairs of buds. One pair is left on a thin shoot, and several inflorescences will fully develop on a thick shoot.
Large-leaved hydrangea blooms from the upper buds of last year's shoots. Therefore, it is important to keep the tops of young shoots that did not bloom last year. The lower buds on the shoots rarely bloom. Old shoots that are more than 4-6 years old do not produce flowers, so they must be removed.

Diseases and pests
It’s worth saying right away that the lion’s share of hydrangea diseases is transferred through seedlings. Therefore, you should buy hydrangea seedlings only in reliable nurseries, and when propagating hydrangeas with cuttings, be sure that the parent plant is healthy.

If the disease affects young hydrangeas, the growing shoots and leaves darken, begin to rot and become covered with “cotton wool” - a soft white bloom. Over time, black blotches appear in the “cotton wool” - sclerotia. The causative agent of the disease remains in the soil, getting there with plant remains. Hydrangea white rot treatment: for fungal diseases of hydrangeas, phytosporin showed high efficiency. Other fungicides may also be used.
Gray mold of hydrangeas
Gray rot
Another dangerous disease hydrangeas, in which the tissues of the plant become watery, soft. In dry weather, the dead tissue dries up, falls out, and holes remain in the leaves and on the stem.

At the same time, a purple or grayish coating is visible on the lower part of the sheet. Over time, the affected leaves fall off. Young shoots are especially affected by this fungus, they are deformed and, as a rule, do not survive wintering. Powdery mildew treatment: hydrangea is sprayed with fungicides - Alirin-B, Fitosporin-M. If the hydrangea disease has severely affected the plant, Chistotsvet, Thiovit Jet, Topaz, Skor, Strobi, Cumulus can be used.

Septoria hydrangeas Such a disease of hydrangeas as septoria manifests itself in the form of brown spots rounded irregular shape, with a light center and a dark rim. Hydrangea septoria affects leaves, but in neglected plants it spreads to young stems and petioles. Over time, the spots merge, the leaves die off. Hydrangea disease septoria reduces the ability of hydrangeas to hibernate. Treatment of septoria hydrangeas: treatment with copper-containing preparations - copper sulfate, copper oxychloride, etc.
Among other common fungal diseases of hydrangeas - common cancer, tracheomycosis wilt, cortical necrosis, phyllostic and ascochitous spotting. In general, the treatment of hydrangeas for fungal diseases is carried out with fungicides. But fungal diseases are not the worst thing that can happen to hydrangeas.

Hydrangea pests
Snails on hydrangeas
Snails love hydrangeas. Most often it is an ordinary amber or a grape snail. They especially like moist shady thickened plantings. Snails on hydrangeas eat buds, young shoots and leaves.
Snails pose a great danger to hydrangeas wintering under cover: mollusks burrow into the soil around the bush, and as soon as the temperature rises in spring, they get out of the ground and feed on the first buds and leaves. Near the hydrangea bush, you can see the clutches of snails.
How to get rid of snails on hydrangeas: in addition to the mechanical destruction of these mollusks and their clutches in spring and summer, metaldehyde or "Thunderstorm" can be used.
These poisonous preparations should not be placed directly on the ground - they clog the soil, and cease to act, mixing with the soil. Chemicals are poured into cups and laid out in a horizontal position around the bush.
Spider mite on hydrangea
If you notice that small yellow spots have appeared on the back of the hydrangea leaf, eventually merging into a marble pattern - this is the spider mite on the hydrangea. Over time, the affected leaf dries out and falls off. If these hydrangea pests have thoroughly populated the bush, you can see cobwebs with mites (with a small lesion, the spider mite is not visible to the naked eye), necrosis appears.
Treatment of hydrangea from Putin's mite: apply insectoacaracids and acaracids - thiophos, preparations Lightning, Akarin, Fitoverm, Vermitek. With a weak damage to the hydrangea by a spider mite, treatment with mineral oil or soap can help.
Aphids on hydrangeas
Settling on hydrangeas, the aphid sucks the juice from the plant, simultaneously polluting it with sugary secretions. They, in turn, serve as food for soot fungi. Aphids on hydrangeas are also dangerous because they can carry viruses. Aphids settle on the lower part of the leaf, with a strong lesion, the hydrangea may turn yellow, and the leaves will fall off.
Treatment of hydrangeas from aphids: with a weak lesion, you can try to simply wash off the pests of hydrangeas with soapy water. Insecticides - Tobacco dust, Spark, Bison, Antilin, Fitoverm, Aktara, Akarin, Tanrek, Commander and other means - are used for large-scale aphids.
Gall nematode on hydrangea
This pest lives on the roots of hydrangeas. Microscopic worms - gall nematodes - form brown round swellings on the root, called galls. The galls rot, the roots die off, the hydrangeas do not receive nutrients. Most often, this pest of hydrangeas affects young bushes.
There are a lot of insects that can harm hydrangeas: bugs, pennitsy, leaf-eating pests (weevils, leaf beetle, caterpillars, scoops, deer, bronzovki, earwigs). However, for a healthy, strong plant and a caring owner, these pests are not particularly scary.

Wrong variety selected
Hydrangea may not bloom due to the whimsicalness of the variety. Not all types of flower shrubs, even with careful care, quickly adapt to a new climate. Sometimes from planting a seedling to the moment of flowering takes from five to seven years.
- When choosing a hydrangea variety, you should study the requirements for its care.
- For example, paniculate hydrangea (Hydrangea paniculata, Unique, Kyushu, Grandiflora, Brussels Lace, Limelight) and tree hydrangea (Annabelle, Hydrangea arborescens) take root in cool regions,
- while large-leaved (Hydrangea acrophyla, Blauer Zwerg, Gerda Steiniger, Ever Peppermint, Endless Summer) and oak-leaved (Hayes Starburst, Incrediball, White Dome) are more suited to temperate climates.

Hydrangea is often planted in suburban areas or in the front garden. own house: her bush blooms beautifully and for a long time. But sometimes it happens that the hydrangea refuses to bloom. Dealing with the reasons is not always easy, since there are quite a few of them.
Reasons why hydrangea does not bloom, and ways to solve the problem
As a rule, the first 2-3 years after planting a young seedling should not be expected to bloom from hydrangeas. Some varieties do not bloom even longer, but most are obliged to please the owner already in young age. If this does not happen, then action must be taken.
Wrong landing site
Hydrangea - tender plant, and under the scorching sun feels uncomfortable. If on open space it will bloom, the flowering will be inferior: it will end quickly, and the flowers will not be as lush and spectacular as expected. But planting a bush in the shade is not worth it either: hydrangeas need at least a few hours good lighting in a day.
If the shade is created by tall trees, they will deprive the flower of moisture and nutrients.
The best location is partial shade: in the morning the sun warmed, illuminated, and hid by lunchtime. If the mistake is in choosing a place, it is worth trying to build a shelter. If this is not possible, you will have to replant the bush, but this can only be done with young plants.
Hydrangea is often planted near a fence that covers the bush from the sun in the afternoon.
The bush is difficult to take root
Hydrangea is a shrub that is not easy to grow: it takes a long time to adapt to a new place of residence. Therefore, at the slightest deviation from the rules of landing or leaving, it can “sick” for a long time, but then, as a rule, everything returns to normal. If in the same place the plant is accustomed to one mode of nutrition and watering, and the new owner has different conditions, the adaptation period may be delayed.
If this is the case, you have to wait, but not allow the plant to die, and for this it is better to feed it, gradually reducing the amount of fertilizer. And so that the change of place does not really introduce hydrangea into stress, it must be transplanted with a clod of earth.
For a hydrangea seedling with a closed root system, the likelihood of transplant stress is minimal
lack of moisture
Drying out of the soil under the hydrangea bushes is unacceptable, as it reacts very painfully to this: leaves, shoots wither, and the bush is no longer up to flowering. A strong heat without watering a bush may not survive at all. Hydrangea is watered weekly in normal weather, and twice as often in drought. This is especially true for young plants.
Hydrangea is moisture-loving, it needs watering once or twice a week, depending on the weather.
However, stagnant water is also harmful, therefore, on clay soils, when planting in a pit, drainage is necessarily placed. For irrigation use water heated sunbeams. If you bring the humidity regime back to normal, next year the bush will be covered with beautiful flowers.
Unskilled pruning
Adult hydrangeas are pruned annually, but this must be done correctly. Pruning begins only after the bush has given flowers for the first time. Act carefully when trimming:
- thickening and old (from 5 years old) shoots are cut out;
- remove the weakest branches, especially those growing inward;
- shorten the shoots of last year, leaving no more than 3 healthy buds.
In autumn, only broken, diseased and dried shoots are removed, and more detailed pruning is carried out in the spring. If the lack of flowering of the bush is observed due to improper pruning, the matter is fixable: once you need to do everything right, and the flowers will appear.
Even if you do not prune hydrangeas in the fall, you need to cut off at least faded inflorescences
Wrong diet
Hydrangeas do not need excessive amounts of fertilizer. This is especially true of nitrogen, which causes an increase in green mass at the expense of flowering. Nitrogen supplements (urea or mullein infusion) are given only in May, they are excluded in summer, and only ash is added in autumn.
Various trace elements can even regulate the color of hydrangea flowers, but this is a separate issue.
On sale there are fertilizers for hydrangeas, depending on the color
If there is an assumption that the bushes were overfed with nitrogen, it is necessary to add more superphosphate, and forget about urea and manure for a while - until next year.
Freezing roots and buds
Even in warm regions, hydrangeas are prepared for winter. Shelter there can only serve as a spunbond, which covers the bush after autumn pruning. In other regions, it is necessary to hill plants, add a good layer of mulch and cover with coniferous spruce branches, and in the most severe climatic conditions- and ruberoid.
No matter how large the hydrangea bush is, for the winter it is covered with spunbond even in relatively warm regions
It is dangerous to leave a hydrangea without shelter, freezing of the soil can lead to the complete death of the root system. Partial freezing is fixable: good feeding and warming for the next winter will eventually return everything to normal.
Diseases, pests
Among the pests of hydrangeas, slugs, aphids and mites are most often annoyed. Slugs are best destroyed by hand, and the rest are eliminated with various insecticides. It is not difficult to deal with pests on the shrub, and it is necessary to do this, since they greatly weaken the plants.
Slugs on hydrangeas appear due to frequent rains and high humidity.
Among diseases, fungal diseases occur (gray rot, peronosporosis, powdery mildew), which are successfully treated with fungicides: copper oxychloride or Bordeaux liquid. Often affects hydrangea and chlorosis: due to iron deficiency, the leaves turn pale, flowering is difficult. Top dressing with iron sulphate corrects the situation over time.

There are many reasons why the hydrangea does not bloom, but most of them are easily eliminated. It is important to understand in time what caused the problem and take urgent measures so that flowers appear on the shrub next year.
