Hydrangea is a beautiful flower that will decorate any landscape. They are different types, but they are all flowering plants.
The right one will allow you to enjoy flowering for many years.
Many summer residents grow large-leaved hydrangea, and oddly enough, it may not bloom. long time.
So, why doesn't hydrangea bloom? Let's consider a number of reasons.
Why doesn't hydrangea bloom?
- Choose a hydrangea variety suitable for your area, as some species short term summer in northern regions They just don’t have time to set flower buds.
- Either large-leaved hydrangea, paniculata or tree-like hydrangea may not bloom due to insufficient development of the root system, too young plant for flowering.
- If you constantly cut off the upper part of last year's shoots of large-leaved hydrangeas due to frost damage, and even if you suddenly do it incorrectly, then the hydrangeas will not bloom or the flowering will be sparse. Explore.
- Insufficient attention to protecting hydrangeas from frost will lead to the following question: “Why doesn’t hydrangea bloom?” Because in the fall, flower buds are formed for the next year, and if frost protection is removed too early in the spring, the buds may be damaged and the shoots may freeze, which will affect flowering.
Sheltering hydrangeas for the winter
In general, hydrangea overwinters well, but the question is whether it will bloom.
As you already know (from the topic), flowering occurs on last year’s shoots, so there’s no need to worry about covering the roots, it’s better to think about the top:
- in the fall, at the end of September frosts may set in, but the hydrangea is still blooming? Then cover the bushes with a double layer of lutrasil or a layer of lutrasil and a layer of greenhouse film. It is too early to hide the bushes for the winter;
- in the second half of October, while the ground is not yet frozen, cover the hydrangeas, cutting off the inflorescences, but leaving the upper part of the faded shoots with large buds;
- young plants can be covered with earth or peat (the flowers will be blue), bending the branches to the ground;
- when the plant is already mature (5-7 years), bending its branches to the ground can break them. You can avoid this by placing stones at the base of the bush under the bend of the branches, then make a cushion from spruce branches or pine needles, bend the branches, again make a leafy cushion and put boards, bricks, stones on top without injuring the plant, secure with a rope. Next, cover it with earth, also making a mound in the central part (hill up). In the spring, partially remove this embankment. To rejuvenate a hydrangea bush at the end of flowering, all thick and old branches can be cut out, leaving young and last year’s shoots that can be bent to the ground;
- In the spring, do not rush to remove the shelter;
- After removing the cover, do not rush to trim seemingly dry and lifeless branches; the buds on them can come to life even in the month of May, the main thing is to water them abundantly. Start pruning no earlier than May - the first ten days of June;
- Do not hide lutrasil until June; leaves that appear after winter or cracked buds will need to be covered for a week or more, as Mother Nature requires.
Hydrangeas do not bloom due to lack of fertilizing
Be sure to fertilize with complex fertilizer at the beginning of budding and in early September before the end of flowering and the beginning of the formation of flower buds.
When buying hydrangea, pay attention to the presence of buds; there should not be any, as this is a sign of artificial stimulation of flowering ( drip irrigation with fertilizer), which in the next 1-2 years will affect the absence of flowering of the bush or that worse plant will die. Therefore, after planting, there is no need to suddenly change the growing conditions of the plant, let it adapt, apply fertilizer every 2 weeks for 2 months, gradually accustoming root system work independently extract nutrients from the ground.
In order for such hydrangeas to bloom in the future and grow a secondary root system, they must be mixed at a distance of 20-25 cm when planting. garden soil with the substrate, avoiding a sharp change in the soil structure.
Hydrangea - popular among gardeners decorative flower. It belongs to the category of capricious crops. Errors in growing technology lead to a lack of flowers. There are several reasons why the plant does not bloom. It is important to diagnose them correctly and then eliminate negative factors.
Features of hydrangea cultivation
Grown as a climbing vine, small tree or bush. The plant has many varieties. The variety of shades and shapes allows you to create a unique decorative combination in the flower garden. You need to figure out why hydrangea doesn’t bloom in the spring, when you notice the absence of buds.
Beginning gardeners may encounter the following problem: they bought a ready-made flowering plant in a store, but at home it withered. It is not possible to achieve the appearance of new buds. The reason for this was most likely special means, which stimulate flowering, but greatly deplete the strength of hydrangea. After treatment, the plant may not form new flowers for several more years.
Advice. In this case, you can help the culture by adding a growth activator.
If you purchase a young specimen and plant it yourself, it can bloom in the first summer after reproduction. However, without proper attention and care, you may be left without flowers even in the second season if the cutting turns out to be weak and has not grown stronger in the first year. And in this case, growth activators help. The drugs allow you to:
Hydrangea blossom
- strengthen and develop the root system;
- form stems and twigs;
- provide an increase in greenery.
Feeding hydrangea: the basis for full flowering
The correct technology for fertilizing hydrangea will help to grow a plant that can bloom normally. The flower needs the first feeding immediately after planting - with a weak solution organic fertilizer for good adaptation. During the growing process, fertilizers are applied according to a certain pattern.
In early spring, the crop needs a lot of nitrogen. This mixture works well:
- urea - 1 tbsp. l.;
- Potassium sulfate - 1 tbsp. l.;
- water - 10 l.
Attention! Watering is carried out at the rate of 5 liters per 1 bush.
An alternative is slurry diluted in water (1:10). Later, at the stage of bud formation, the plant is fed with mineral complexes with a high content of phosphorus and potassium. To further strengthen the bush, pour potassium permanganate solution over the root zone and the stem itself. The procedure must be repeated three times. In this case, there should be no situations where hydrangea does not bloom.
In summer, the shrub must be treated with a strengthening complex agent for flowering crops. Nitrogen must be used carefully during this period. Its excess will lead to strengthening of the greenery and the inflorescences themselves, which will negatively affect the strength of the branches. Total number fertilizing in the summer months is limited to 3 times.
During flowering, gardeners also use non-standard fertilizers:
- lactic acid (yogurt, kefir, whey);
- soaked sour bread.
Advice. In autumn, hydrangeas need to accumulate potassium and phosphorus, so repeat the course of applying mineral fertilizers.
How to understand why hydrangea does not bloom
The main reasons for the absence of buds in an adult hydrangea:
Before experienced gardener There is no question about hydrangea flowering. The main factor in this is proper care of the plant.
How to make hydrangea bloom: video
It often happens that a gardener buys a flowering hydrangea in a container, plants it in the ground - but it dries out and the flowers wither. Or after wintering, hydrangea does not bloom - neither in the first, nor in the second, nor in the third year. Why doesn't hydrangea bloom? How can you help the plant? Let's figure it out.
Why hydrangea doesn't bloom: typical gardener mistakes
The most problems arise with large-leaved hydrangea (garden, marcophila, large-leaved), since not all varieties of this delicate plant are adapted to our conditions. We will talk about large-leaved hydrangea.
Hydrangea buds are freezing
Large-leaved hydrangea blooms on last year's shoots, buds are laid on the tips of the shoots in the fall. If you cover the hydrangea too late, or open it too early, the buds will freeze and the hydrangea will not bloom. What can (and should) be done? The remaining leaves on the bush are torn off, the bush itself is tied with a rope, wrapped with covering material and film. Mulch is poured around the bush - dry leaves, straw. With the arrival of frost, the hydrangea is bent to the ground, fixed with staples, and covered with spruce branches. In the spring, the hydrangea is opened gradually, finally removing it from its shelter with the disappearance of night frosts, that is, until the beginning of summer. 
Improper pruning of hydrangea
If you cut off the shoots of large-leaved hydrangea in spring or autumn, is it any wonder why the hydrangea does not bloom. We remind you once again that hydrangea blooms on last year’s shoots, in the upper part of the shoots.
Improper feeding of hydrangeas
If the hydrangea is overfed with nitrogen fertilizers, the plant may not have time to harden by the arrival of frost, and, again, will not survive the winter. Therefore, to feed hydrangeas, like most garden plants, remember one simple rule: in late spring and early summer we apply nitrogen fertilizers (for green growth), in the summer - potassium-phosphorus supplements(to maintain flowering), at the end of summer - phosphorus fertilizers (to help the hydrangea survive the winter, preserving the buds of the shoots for flowering next year). 
Problems with growth and acclimatization of the root system
First of all, this is a problem with large-leaved hydrangeas, which were planted from containers in open ground. It often turns out that sellers of hydrangeas feed the plant with fertilizers, organizing drip watering, to make it bloom wildly. This hydrangea has a poorly developed root system - it is not used to getting food for itself with roots, but received everything ready-made with fertilizers, and on special soil. And when you plant it in your garden, the spoiled plant is unable to absorb nutrients with its weak roots, and withers before your eyes. Without emergency measures, such a hydrangea not only will not bloom, but it may even disappear altogether. 
What to do in this case? Correct the “disservice” of sellers and gradually wean hydrangea from bait. Firstly, container blooming hydrangeas no need to cut roots, as is often advised, you don’t need them soak or shake off the substrate. The plant already spends a lot of energy on flowering, and under such conditions the hydrangea will no longer be able to develop the root system. It will wither away.
Secondly, the first two months add fertilizer, gradually reducing the dose.
Thirdly, in preparation landing pit for hydrangea, make sure the area will be shaded at midday, otherwise garden hydrangea may not tolerate the heat, and even heavy watering will not help. You need to add a mixture of soil from your garden with a nutrient substrate from a container of hydrangeas into the hole, and in an area of at least 20 cm from the roots of the hydrangea. In this way, you will help the hydrangea adapt to new conditions.
Hydrangea variety is not suitable for climatic conditions
Large-leaved hydrangeas have recently begun to be planted in open ground in our area; new varieties appear all the time, which are praised and convinced that there are no problems with care. And then buyers, especially from northern regions countries cannot understand why hydrangea does not bloom. It’s sad, but even if all agrotechnical practices are followed, greenhouse hydrangea seedlings do not always have time to set buds for the next year during the warm season (if the summer is short). As a result, we get a gorgeous green bush, but the hydrangea does not bloom.
Don't rush the hydrangea - let it develop a strong root system that could nurture the color. For paniculate hydrangeas, this period takes about 6 years. In addition, hydrangea can bloom simply because insufficient watering, bad location, heavy soils, . Just carefully study the rules, choose (if you are a beginner) - and you will definitely succeed!

There can be many reasons why hydrangea does not bloom. Garden beauty capricious. To grow this magnificent flower on your site and enjoy its flowering, you need to make some effort. It is necessary to study its preferences, determine the need for watering and lighting. In this case, it is necessary to take into account the characteristics of the soil, planting location and plant variety. If you carefully analyze the conditions in which hydrangea grows, you can discover the reasons for its problems and correct the mistakes made.
Show all
Poor place to plant a seedling
Hydrangea feels uncomfortable on open places being under the scorching rays of the sun all day. The tender leaves of many varieties droop lifelessly and burn in the heat.
On sunny place The plant will be saved by low planting. Tree trunk circle the bush should be 10 cm below ground level. It must be mulched with coarse-fiber peat or sawdust to the surface of the ground. In such conditions, the plant can develop and bloom normally.
In hot and sunny regions it is better to grow paniculata hydrangea. With regular moistening, it will withstand direct sunlight all day long without harming flowering.
In deep shade, under the crowns of large trees, hydrangea is unlikely to delight with its lush color. The perennial does not develop well in heavy shade, 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 poorly and the situation cannot be corrected in any way, you need to replant 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 dormant.
Having picked up 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 is added mineral fertilizer. Hydrangea loves acidic soil and grows quickly in it. Therefore, the soil for it needs to be acidified with a solution of sulfuric acid (1 tsp per 10 liters of water).
The plant must be replanted very carefully, along with a lump of earth. If the root system is damaged during replanting, the plant will not bloom for a long time.
Lack or excess moisture
Hygrophilia is the main feature of hydrangea. The shrub has the botanical name Hydrangea. Translated from Greek language"hydrangea" means "water vessel". If there is a lack of moisture, the plant stops blooming. Its roots should always be kept moist. Do not allow the earthen ball to dry out near the roots. If the weather is dry, without watering the hydrangea may die.
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. The 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. If there is excess moisture, hydrangea may reduce or stop flowering. An abundance of water leads to rotting of the roots and death of the plant. Oakleaf hydrangea tolerates moisture accumulation near the roots more difficult than others. It only needs well-drained soil. So that the water in clay soil does not accumulate, you need to add pine bark to it.
For irrigation, it is better to use rain or filtered water. Tap water must be left to stand for 5 days before watering. To water a bush once, you need 1-1.5 buckets of water. To prevent moisture from spreading, it is worth making an earthen border at the base of the bush.
In a garden surrounded by large and powerful hydrangea trees, there will not be enough moisture. The roots of the trees will take water from the flower. Even if tree roots are removed when planting a perennial, they will grow within a year.
Adaptation after disembarkation
Very often after disembarking a healthy flowering plant into open ground, it loses its decorative qualities and stops flowering. The sharp deterioration in the condition of the flower is due to the lack of usual feedings. Hydrangea sellers often abuse fertilizers and overfeed the plants, achieving lush flowering and rapid growth. Finding yourself in natural conditions, flowering bush starts to hurt. It 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 hydrangea from a container into the soil, you do not need to trim the roots and shake off the substrate. It will be very difficult for a weakened plant to restore its root system. The remaining soil in the container must be mixed with garden soil and poured into the root zone.
In the first year, you need to regularly fertilize hydrangeas, gradually reducing the dosage. It is important to create a plant ideal conditions in the first months after transplantation, avoiding drying out and stagnation of water in the root zone. When the hydrangea gets stronger, it will begin to develop and bloom.
Incorrectly selected fertilizers
If hydrangea is overfed with nitrogen fertilizers, the young shoots will not have time to harden before frost. Vulnerable branches will die during frosts along with flower buds. To preserve young shoots of perennials, nitrogen fertilizers must be applied in the spring. At the beginning of bush growth, 25 g of urea, 40 g of superphosphate and 35 g of potassium sulfur are added per 1 m² of soil. This will allow the plant to develop lush greenery.
When the first buds appear, the amount of nitrogen fertilizing is reduced. Otherwise, all the plant’s energy will be spent on the formation of greenery, and not on flowers. To maintain lush flowering, 1 m² of land is fertilized with 80 g of superphosphate and 45 g of potassium sulfur.
When the plant fades, you need to put 15 kg of compost or rotted manure under it. Fertilizers will help the perennial to survive the winter safely and preserve buds for flowering next year.
Frozen buds in winter
Hydrangea blooms on last year's shoots. Buds of future flowers are laid in autumn time. If the plant is covered too late on the eve of winter or opened very early in the spring, the buds may be damaged by frost. Some varieties of shrubs (Endless, or Forever&Ever) bloom on shoots of the previous and current year. Flowers may appear on them, but in much smaller quantities than usual.
To avoid kidney freezing and ensure lush flowering, you need to trim the lower leaves to the middle height of the bush 3 weeks before the first frost. This will allow the shoots to become woody and stronger. The existing inflorescences will help protect flower buds from frost. They should not be cut.
Before the first frost, the buds are covered with burlap or lutrasil. On the eve of permanent frosts, remove the remaining leaves, tie the bush, wrap it in burlap or lutrasil and bend the branches to the ground. To prevent branches from breaking under the weight of snow, a log or roller made from tightly tied pine branches is placed under them. You need to pour it under the root pine needles. The top of the plant is covered with film.
The film is removed in the spring, as soon as the snow melts, so that the garden hydrangea can be ventilated. The bush can be lifted. Lutrasil should be removed only when a stable above-zero temperature has been established. With this method of sheltering for the winter, the plant will bloom earlier than usual.
Unsuccessful bush pruning
If at autumn pruning the buds of future flowers have been removed, the plant is in allotted time will not bloom.
Hydrangeas should be pruned only when necessary. Young plants should not be touched until they begin to bloom. The first flowers appear on the perennial after 2-3 years. Paniculate hydrangeas can bloom only in the 6th year.
In the fall, most varieties of hydrangeas do not need to be pruned. It is better to carry out spring pruning in more late dates when damage caused to the bush by frost is visible. Remove frozen buds, shoots and broken branches.
The decorative appearance of the shrub depends on proper pruning. Some types of hydrangea have a very developed shoot-forming ability. If you do not thin out the bush, it will quickly thicken and bloom less abundantly with small inflorescences. On a severely neglected perennial, flowers may not form.
It is necessary to cut out small branches inside the bush that do not produce full-fledged inflorescences.
To enhance flowering, last year's shoots must be shortened, leaving 1-3 strong couples kidney One pair is left on a thin shoot, and several inflorescences will fully develop on a thick one.
Large-leaved hydrangea blooms from the upper buds of last year's shoots. Therefore, it is important to preserve 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 need to be removed.
Diseases and pests
The reason why hydrangea does not bloom in the garden may be alkalization of the soil. Even if the flower is planted in the most suitable soil, over time the soil will become more alkaline. Due to the reduced acidity of the soil, the plant's absorption of iron is impaired and iron chlorosis (iron deficiency) develops.
A sign of chlorosis are prominent green veins on a lightened and yellowed background of the leaf blade. The leaves decrease in size, curl and fall off. The shape of buds and flowers changes. They dry out and crumble.
You can notice a decrease in soil acidity by changing the color of the inflorescence. If blue or blue flowers began to acquire a lilac color, the acidity of the soil decreased. It will bloom on slightly acidic and neutral soil. pink hydrangea.
Hydrangea growing in lime-rich soil often suffers from chlorosis. Only tree hydrangea can withstand lime in the soil.
To cure a plant, you need to prepare a solution potassium nitrate. It is prepared from 40 g of potassium nitrate and 10 liters of water. Hydrangea is watered with the mixture for 3 days in a row, and on the fourth day iron sulfate is added to the soil.
You can quickly and easily solve the problem of chlorosis with the help of rust. It is scraped off from large metal objects and mixed with root soil. You can bury rusty nails or tin lids near the roots.
To prevent the development of chlorosis, you need to regularly water the bush with special fertilizers for hydrangeas.
In spring, chlorosis can develop due to sharp temperature fluctuations during the day and night. Metabolism in the plant is disrupted if the roots are in cold soil and the above-ground part warms up. sun rays. As the soil warms, the plant recovers.
In addition to chlorosis, aphids can interfere with flowering, spider mite And powdery mildew. They prevent plants from developing, slowing down the flowering process or stopping it. Used for pest control modern means on biological or chemical basis.
Wrong variety selected
Large-leaf hydrangea has recently begun to be planted in open ground. Many of its varieties are painfully tolerant of climatic conditions in the northern and northwestern regions. If hydrangeas are given proper care, they can take root and form a healthy bush. But the gardener may not wait for flowering. The reason for the lack of flowers on the bush may be too short summer. The perennial does not have time to form buds for flowering for the next season.
To enjoy the magnificent caps of hydrangea inflorescences, it is better to select unpretentious varieties. For northern latitudes white will do tree hydrangea. It is rarely affected by pests and diseases, is frost-resistant and does not die in drought. The plant will delight you with inflorescences the very next year after planting in the ground. The most popular variety in the north is tree hydrangea Annabelle.
Many beginners in the field of floriculture often make simple mistakes when growing hydrangeas. Because of this, plants may stop flowering, and all useful material let the foliage develop.
Hydrangea is perennial shrub, which produces flowers of amazing beauty. But you can’t always see these flowers on your plant. When growing these plants, you should know why hydrangea does not bloom, but only produces foliage. This will help gardeners observe the flowering of their plants every year.
White flowers
Hydrangea has more than 80 varieties, and they can differ in a large number of characteristics. The main part of the varieties are small shrubs, 1-2 meters high, and the vines can climb to a height of more than 30 meters.
Hydrangea
Flowering plants begin late spring and lasts until late autumn. The main part of the flowers is white, but the flowers of certain varieties of hydrangea can be colored pink, red, blue and lilac colors. Typically, color depends on the acidity level of the soil.
Reasons for not flowering
Many gardeners, having decided to grow hydrangea on their garden plot, cannot achieve flowering. There may be several reasons, and you should know the main ones in order to avoid mistakes when growing plants.
- Not correct pruning bushes
- Lack of moisture.
- Underdevelopment of the root system.
- Scam when purchasing.
- Incorrect transplant.
- Insufficient lighting.
- Frosting of kidneys in winter.
- Poor nutrition.
- No choice suitable variety.
- Diseases and pests.
Bush pruning
Hydrangeas, like others shrub plants, timely and correct pruning is necessary. It greatly influences the amount of foliage and the abundance of flowering. Improper pruning is often the reason why hydrangeas do not bloom and produce only foliage. This phenomenon is very common in large-leaved hydrangea varieties.
As a rule, most of the pruning is done in the spring after the snow has melted. Work on pruning hydrangea bushes is rarely left in the fall, only the faded parts are removed. Spring pruning is done before foliage begins to form. Pruning methods may vary for each person. a separate type hydrangeas.
Watering
Hydrangea loves moisture very much. Even its name in Latin is translated as “vessel of water.” Watering for bushes should be plentiful. IN summer period Up to 50 ml of water is used for each bush.
Watering is done regularly. In summer, the bushes are watered twice a week. If the weather is rainy, watering should be reduced to once. The amount of watering should be adjusted according to the current weather.
Root system
Young plants that have only recently been planted in the soil have a weak root system. They need a long time to finally strengthen and begin to produce flowers.
Full flowering of plants begins only in the 4th year of hydrangea growth. Therefore, you should not panic if your hydrangea does not bloom immediately after planting. At proper care You can get stunning flowers every year.
Purchase of planting material
When purchasing hydrangeas, you should not turn to little-known sellers of planting material. Often unscrupulous sellers can use growth and flowering enhancers. When purchasing, you can observe excellent flowering, but having planted such plants in your soil, flowering may stop.
The use of flower enhancers puts a very high stress on plants. Subsequently, such a plant will not produce flowers for a very long time. And in the worst case scenario, you may not see flowers at all.
Buy planting material only in established companies, and before purchasing, you should carefully study the reviews about it.
Transplanting bushes
Incorrect transplantation very often becomes the reason why pink hydrangea does not bloom, but only produces foliage. Beginner gardeners can easily damage the root system, disrupting the plants’ normal metabolism.
Planting flowers
Also, choosing a growing container that is too cramped or too spacious indoor plants may lead to a slowdown in development and, as a result, the cessation of flowering of hydrangea.
Choice suitable soil is also very important, because a sharp change in soil composition can negatively affect general condition plants.
Lighting
Reason poor flowering or its absence may result from insufficient lighting. This is often observed in places where natural sunlight is not fully available.
To solve this problem, you should establish additional lighting using other methods or transplant the plants to places where sunlight there will be plenty.
Pink flowers
Shelter for the winter
In severe frosts, flowering buds can easily freeze. Such buds will no longer be able to produce flowers, and all that remains is to cut them off along with the damaged stems. To prevent this from happening, the plants are covered for the winter.
Shelter for the winter
- You should tie the hydrangea stems together and cover them with sawdust. After that all that remains is to sprinkle them with earth.
- If it is possible to cover the hydrangea with a non-woven covering material, then you should take advantage of this opportunity.
- Coniferous branches would be a good covering material. They will not only save the bushes from freezing, but will also increase the acidity of the soil, which hydrangea bushes love.
- Plants can be covered even if all the leaves have not yet fallen off. Neither pests nor diseases overwinter on hydrangea leaves.
Feeding
Fertilizer application
For full flowering, hydrangeas need regular but moderately dosed feeding. An excess of nitrogen fertilizers is the reason why it does not bloom. paniculata hydrangea, but only gives foliage. The flowering of the bushes stops, and the beneficial substances are used for increased foliage formation.
- In the spring, at the beginning of bush growth, you should apply one square meter soil 25 gr. urea, 40 gr. superphosphate and 35 gr. potassium sulfur.
- With the onset of the budding phase, the supply of nitrogen fertilizers decreases. Apply 80 grams per square meter of soil. superphosphate and 45 g. potassium sulfur.
- The use of nitrogen fertilizers is important after flowering has ended. Under each bush, 15 kg of compost or rotted manure should be added.
There are special fertilizers for hydrangeas. They contain a set of minerals and trace elements necessary for the full development of plants. You can use them as the main feeding. Before use, you should carefully study the instructions.
Selection of varieties
Each plant requires certain growing conditions. It is not always possible to achieve them in different regions countries. Varieties that are initially accustomed to a lot of light and heat will feel uncomfortable in northern regions.
Variety selection
On the other hand, a variety intended for cultivation in northern climates is unlikely to take root in hot regions with a dry climate.
Choosing the right variety is one of many basic conditions for the full growth and flowering of hydrangea.
Diseases and pests
Diseases and pests on hydrangeas are rare, but even they suffer from similar troubles. The most common problems with hydrangea are:
They do not damage flowers directly, but can interfere with plant development, delaying the onset of flowering or stopping it altogether. To combat diseases and pests, modern biological or chemical based agents, as well as traditional methods, should be used.
Knowing why hydrangea does not bloom and produces only foliage, you can easily eliminate all the reasons that interfere with the full development of the plant. By putting these tips into practice, you can enjoy the pleasant flowering of your pets every year.
