Hydrangea, or hydrangia, is a treelike flowering shrub that belongs to the Hortensia family. It is difficult to remain indifferent at the sight of these beautiful large inflorescences. This family includes about a dozen species of shrubs, vines or small trees.

Description of culture

Hydrangia appeared in England and France at the beginning of the fourteenth century and was represented by only 2 species: white and scarlet.

A hydrangea bush can grow up to 3 meters in height, but there is a liana-like species that can reach a length of 30 m.

In Europe, only deciduous hydrangia are grown.

Hydrangea

Types of hydrangeas

The following types of plants are found:

• large-leaved;
• panicle;
• tree-like;
• creeping.

The flowering period lasts from late spring to late autumn.

There are two types of flowers in the inflorescences:

• fertile, or small-fertile;
• sterile, or sterile.

Fertile ones are in the center of the inflorescence, and infertile ones are at the edges. Separate types have inflorescences containing only fertile flowers. There are two types of inflorescences on the hydrangea bush: paniculate and corymbose.

Hydrangeas are grown with inflorescences of the following colors:

• white;
• blue;
• purple;
• lilac;
• pink;
• red.

The color of the inflorescences depends not only on the variety, but also on the composition of the soil on which the bush grows. On acidic soils, the inflorescences will be blue, on neutral (pH 5.5) - beige, on alkaline - pink or lilac. Blue color Hydrangia flowers growing on acidic soil are given aluminum compounds, which are found in acidic soils.

Garden hydrangea

The hydrangea fruit looks like a box, in which there are from 2 to 5 separate chambers, each of which contains small seeds.

One of the most popular types of hydrangia is a large-leaved species, the inflorescences of which have sterile large flowers. About 600 varieties of this shrub have been bred.

Attention! Hydrangea - poisonous plant therefore it is forbidden to use it for food.

Growing features

Hydrangea grows best in acidic soils. For better air penetration into the soil, the ground around the shrub must be periodically loosened.

Hydrangea does not grow well in sunny areas, so it is better to choose a place for planting in the shade or partial shade. In a sunny area, the plant develops more slowly, and the flowers become smaller.

Hydrangea grows poorly in sunny areas

Watering hydrangia should be done with settled water or rainwater, since the shrub does not tolerate lime well. Watering time is morning or evening. This will allow the plant to avoid sunburn... Once a week, at least 2 buckets of water are poured under an adult bush.

Planting is usually carried out in the spring when there is no night frost.

2-3 weeks before planting, they dig a hole, up to 0.5 m deep, and with sides up to 0.7 m. Sod, leafy soil, sand and peat are poured into it in equal proportions. It is not recommended to prepare alkaline soil, since its alkalinity is a possible cause of hydrangea chlorosis. Further, mineral fertilizers and organic matter are introduced into the planting hole. The root collar of the seedling should be at ground level.

Hydrangea propagates by green cuttings.

Starting from 3-4 years old, they perform an annual molding of the bush.

Why does hydrangea wither

If the care of the shrub is correct, then it has a luxurious look throughout the growing season. If the technology of growing a plant is not followed, hydrangia can get sick.

What to do if hydrangea dries

First you need to determine the cause of the disease. If the leaf dries up, then the reasons for this may be:

• incorrect soil pH;
• direct sunlight;
• watering the plant with tap water;
• lack of moisture in the soil;
• insufficient or excessive amount of trace elements in the soil.

Incorrect soil composition

In order for the shrub to develop well, it must be performed important condition- the soil can be acidic or moderately acidic. For hydrangea, the pH should be in the range of 4.0-6.0. In the case of alkaline soil, the leaf will begin to dry out over the entire area.

Attention! The color of the leaves of the plant depends on the acidity of the soil. The more acidic it is, the darker the leaves of the hydrangea.

If the soil is alkaline, then the acidity of the soil can be restored by irrigation with acidified water (for example, with the addition of lemon juice).

Insufficient plant nutrition

If the leaves turn black or yellow, it is possible that there is not enough iron or nitrogen in the soil.

During the flowering period, it is necessary to feed the hydrangea. complex fertilizer designed for flowering plants.

Fertilizing the shrub with iron chelate

Also, a lack of trace elements can occur in the spring, when the hydrangea begins to actively develop. How to reanimate hydrangea in this case? To do this, you need to carry out foliar feeding of the shrub with iron chelate.

However, hydrangia responds poorly not only to a lack, but also to an excess of fertilizers. Therefore, after the end of flowering, it is necessary to reduce the dose of applied mineral fertilizers.

Excessive sunlight

One of the reasons why hydrangea leaves dry out is because the plant is not in the shade, but in the sun.

Hydrangea does not develop well in direct sunlight. Therefore, resuscitation consists in transplanting a plant in partial shade or creating an artificial shade using a special shading mesh.

Excessive sunlight

If the shrub is home and grows indoors, then it is best to place the pot on the west or east window. You also need to make sure that the leaf does not touch the window glass. If the sheet touches the glass, the sun can burn it.

Insufficiently moist soil

Due to a lack of moisture, the leaves of the bush will dry out over time.

Hydrangia is a moisture-loving plant, therefore, mandatory regular watering will allow you to get beautiful flowers.

To revive the street bush will allow an increase in watering, as well as mulching the soil. If the bush is indoor, then you can use a humidifier. Instead, you can install a container near the flower, into which water is periodically poured.

However, the plant also does not like an excess of moisture, since this contributes to the development of root rot.

Using hard water for irrigation

Tap water contains many impurities, including lime. And hydrangea is quite sensitive to them. Therefore, it is best to use settled water for irrigation. For this, you can use special open containers, which are best placed in the sun. In this case, you can get warm and soft water for irrigation.

Landing errors

One of the reasons why hydrangea leaves dry at the edges are the mistakes that were made when planting the plant.

Damage to the root system

Hydrangea has a very delicate root system, so the plant must be transplanted very carefully, without damaging the small roots. Damage to them can lead to the fact that the bush will be difficult to take root and hurt for a long time.

Attention! Buying a seedling is a very responsible business. It is important to check the health of the root system.

Also, you cannot prune the roots when planting. It is allowed to trim the roots only if they are rotten, diseased or damaged by insects. Rotten roots are dark brown, and healthy ones are white. The cut sites are processed with crushed activated carbon.

Watering with the addition of Zircon, which is carried out once a week, can help the better survival of the plant.

Errors when choosing a landing site

If the soil is not acidic, but alkaline or neutral, then the plant will be difficult to take root. Therefore, in in this case it is necessary to acidify the soil, otherwise the bush may dry out.

If the soil is not acidic, then the plant will be difficult to take root.

If a garden is chosen for planting, then it is important not to place the seedling in a draft; it is also necessary to protect it from sudden temperature changes and hypothermia.

Hydrangea diseases

What to do if hydrangea leaves wither? Perhaps the plant is sick. In order to choose the right treatment method, it is important to accurately determine the disease.

Dry blackening

If the edges of the leaf are covered with brown spots and become dry, then this indicates that:

• the plant is watered with hard water;
• the leaf was sunburned.

After the stains appear, the foliage will wither and wither.

Wet blackening

The leaves darken and lose their firmness. This may be due to:

• sudden changes in temperature;
• exposure to the draft of the place where the bush grows;
• excessive watering;
• heavy soil.

Why is the garden hydrangea still withering? A possible cause is a fungal infection of the plant.

White rot

Fungal root disease. With such a disease, the bush gradually dies, since the affected root system cannot provide the plant with the required amount of nutrients.

White rot

Symptoms:

• white, cotton-like plaque on the shoots;
• blackening of shoots.

Treatment

To treat the affected plant, fungicides Fitosporin, copper oxychloride, etc. are used.

Gray rot

Symptoms:

• Flower tissues become soft and watery;
• The affected parts of the plant die off in a dry environment. After them, holes remain on the stems;
• In a humid environment, the affected areas become covered with a gray coating.

Treatment

The diseased areas are removed mechanically. Then houseplants are treated with Chistotsvet, Fundazol or Skor. Garden views processed by Rovral Flo 255 SC, every three weeks.

Septoria

Symptoms

The appearance of dark brown spots, up to 6 mm in size, on the leaves. The affected leaves gradually begin to dry out and die off.

Treatment

Treatment with copper-containing preparations, for example, copper sulfate.

Powdery mildew

Symptoms

The formation of yellow-green spots on the leaves. Gradually, the spots darken and acquire a brown color. The back of the leaf is covered with a purple or gray coating. Winter for a diseased plant usually brings death.

Powdery mildew

Treatment

At the first symptoms of damage, the fungicide Fitosporin is used, and in an advanced form - Skor, Topaz or Purest flowers.

Thus, when purchasing a seedling through a store or on the market, you need to make sure that the young plant is not susceptible to fungal disease.

Disease prevention

Inspection of seedlings and proper care of the plant is the main prevention of disease. It is imperative to loosen the soil around the plant during the entire growing season.

In the spring, you can treat the plant with copper-containing preparations, for example, copper sulfate (100 grams per 10 liters of water). You can also use drugs Topaz, Fitosporin, etc.

Copper sulfate

At the end of spring, it is necessary to make nitrogen-containing dressings, in the summer - phosphorus-potassium, and in the fall - phosphorus.

How to save a wilted hydrangea

If the bush is dead, then you can try to revive it. If the plant is garden, then in the spring all frozen parts are removed. If the plant is affected by rot, then the cut is performed 1 cm below the affected part. The cut points must be sprinkled with ash, activated carbon, etc. After trimming each affected area, the pruner is disinfected. The treatment of the bush is carried out with drugs, depending on the disease.

Wood ash for fertilization

How to revive a cut hydrangea? If a wilted flower is in a vase, then you need to get it out of there, cut it obliquely lower part and place the plant in boiling water for 3-5 minutes. After the air bubbles have finished coming out of the stem, you need to get the plant, cut off the part that was in boiling water, and put the flower in cold water... After that, your vase will look festive again.

Hydrangea dries at home in a pot

If the beginning disappears indoor plant, then it must be brought into the house (if the pot was on the street), cut off the entire affected part and treated with HOM for fungal infections.

In the case when even the entire green part has died, there is still no need to throw out the hydrangea. Continue to water the potted soil sparingly. Perhaps, after this, the dormant buds will wake up, and the plant will start growing again.

Hydrangea - amazing flower, which has about 90 species. However, in order for this plant to please your eye, you will need to work hard, otherwise the hydrangea leaves will begin to turn yellow, dry out, and the plant itself will die altogether.

Why does hydrangea dry out?

There can be many reasons, among them:

1. Poor watering;
2. Dry air in the room where the hydrangea grows;
3. Wrong transplant;
4. Improper lighting;
5. Insufficient fertilization of the soil (reduced acidity);
6. Lack of foliage spraying;
7. Incorrect choice of soil for planting.

Hydrangea, leaves dry, what to do?

First of all, you need to decide whether the acidity of the soil is correct, where the hydrangea grows. The optimum pH for the soil in which the hydrangea grows is 4.0-5.5. That's why leaves turn yellow with a lack of the necessary acidity.

In this case, pour acidified water on the flower (5-7 drops of lemon per liter of water). In the future, use special fertilizers.

Hydrangea generally needs loose soil so that air and moisture can easily penetrate.

Also leaves turn yellow with a lack of iron with nitrogen... This often happens during a period of active growth (spring), so remember to fertilize.

This should be done starting in February once every two weeks. In winter, the plant does not bloom, so no root feeding is needed at this time of year.

Hydrangea, leaf tips dry.

In this case, the reason is either insufficient watering, insufficient foliar spraying, or too dry indoor air where the hydrangea grows.

Hydrangea home blooms in spring, the flowering period lasts 1.5-2 months. So that at the moment of flowering the plant pleases you with a riot of flowers, of which there can be from one to seven on one bush, you need it water on time.

Wait for the top layer of soil in the pot to dry and water again. You need to watered warm water, not tough! Disease can appear from hard water - chlorosis. The signal will be yellowed leaves with green veins.

Also remember to spray the leaves and flowers with water and keep the indoor air humid. For a hydrangea, these two factors must be properly balanced - the air is moist, the soil is watered, but do not overdo it, excess moisture is also harmful, the roots will begin to rot.

The main sign of waterlogging of the soil is the appearance of black spots with a yellow outline on the leaves..

Did you know? In order for the hydrangea to bloom longer, it must be planted in a small pot and placed on a window on the north or east side of the room. You need to leave 3-4 of the strongest shoots, and remove the rest of the fallow. After flowering, in July, the hydrangea is pruned. If not pruned in time, the flower may not bloom next year!

Hydrangea, dry leaves, reasons.

Improper lighting is considered to be another reason why hydrangea leaves dry. Hortense categorically does not like direct sunlight, so she has no place on the windowsill! It is better to put it on the table near the window, there is a lot of light and the sun will not burn the leaves of the plant, which will simply darken from direct rays.

Homemade hydrangea, leaves dry after transplanting.

Another important process in the care of a hydrangea, its transplant is considered, since incorrect transplantation will lead to drying of the leaves and flowers of the plant. The home hydrangea grows for four years, then you plant a new one.

In order to transplant a hydrangea, use a wide pot, this is because the roots of the hydrangea develop horizontally. Place drainage in the bottom of the new pot.

Then, dig the flower out of the old pot, do it carefully so as not to damage the root system. So dig out, keeping an earthy ball around the roots.

Sit in new pot it is necessary so that the stem goes three centimeters into the ground, it is not necessary deeper. And do not forget that the soil for transplanting must be slightly acidic. By the way, you can use geranium soil for planting hydrangeas.

In many summer cottages, hydrangea is now blooming - white, pink and even blue. If you are also not averse to having such a bush, or you already have one, but does not bloom, we talk about planting a hydrangea and caring for it. How to feed, whether it is necessary to cover for the winter - and even how to change the color of flowers.

Hydrangea varieties: planting and care. How to shelter for the winter

She brought a pink hydrangea from the south, and she died in the winter. What hydrangeas can be planted in the Northwest?

In this region, the usual hydrangea (gray) grows well and blooms, sometimes it is called umbrella because of the shape of the inflorescence, reminiscent of an open umbrella. It blooms with large caps of white inflorescences. In the same way, the panicle hydrangea, which usually has pink or white inflorescences in the form of a panicle, freezes, but it recovers well.

Planting hydrangeas should be sheltered from cold northerly winds in a sunny location. Bushes at panicle hydrangea more spreading than the umbrella. You can even grow a broadleaf southerner, but you will have to cover it for the winter, like a climbing rose.

After a harsh winter, hydrangea froze. How to save?

Itself will be saved. Freezing is not fatal. The dried ends of the branches will need to be pruned in the spring. Take your time to just do this before the leaves appear. Then it will become clear to what place the stems have dried. Twigs immediately appear from the lower part of the stems, on which flowers bloom in the same summer. It's just that the length of the stem is too small for cutting.

Do I need to cover the panicle hydrangea for the winter?

The panicle hydrangea freezes under the level of snow cover only in severe winters. And since the bush itself is spread out, it is enough to plant it in that dream, where a high snowdrift is sweeping, and put a not very heavy wooden lattice on the bush itself in the fall.

Climbing hydrangea is easy to remove from walls or supports, so don't be lazy to do it in late fall. Then it will be very easy to cover it with spruce branches for the winter so that it does not freeze. And in the spring, until the return frosts have passed, replace the spruce branches with lutrasil, since young leaves do not tolerate negative temperatures poorly.

Hydrangea feed

How and when to feed hydrangea?

After the end of the frost, feed with any complex fertilizer. By the way, all hydrangeas are responsive to AVA fertilization. It is introduced 1 time in 3 years, embedded in the soil along the perimeter of the crown of the bushes for an incomplete tablespoon of granules. In this case, you can not give any other mineral supplements.

To enhance the resistance of plants to the climate of the North-West, spray them on young foliage with the preparations Zircon, Epin-extra or Novosil (formerly Silk).

I brought ash under the hydrangea, and brown spots appeared on the leaves. Is one somehow related to the other, or is it a coincidence?

Hydrangea grows exclusively in acidic soils. It cannot be fed with ash. Top dressing should be given one that acidifies the soil (Azofoska, Nitrofoska, Ekofoska, "Kemira"). Top dressing is done before budding, and humus is added in the fall.

It is good to sprinkle coniferous needles under the plants (at least from the Christmas tree), fallen twigs of thuja, or acidify the soil with citric acid (1 teaspoon per 10 liters of water), potassium permanganate color pink(a bucket under a bush) once a season.

Why did dark spots appear on the leaves of hydrangea in the midst of flowering and even a border along the edges of the leaves?

The plant complains of a lack of potassium. Do not be greedy - feed with any potassium fertilizer (1 tablespoon of any potassium fertilizer per 10 liters of water, and a bucket under the bush). I emphasize again - in no case use ash instead of potassium.

Hydrangea: flowering and reproduction

I really want to have a pink hydrangea. How to propagate it?

Any hydrangea is easily propagated by layering (for this in the spring, press one of the lower stems to the ground). Cover this area with a piece of plastic to keep it constantly moist. Plant the next year, separating it from the bush.

In addition, you can take root offspring, but before separating them from the mother bush, you need to dig out the soil under them to the mother bush and separate where your own roots, even small ones, are.

You can also use stepchildren in early summer, just like dahlias.

I got a climbing hydrangea, I have had it for several years, but I don't even think to bloom. What's the matter?

Climbing hydrangea (also called weaving, climbing, petiolate) blooms only when it begins to grow large leaves, and while they are small, the plant does not bloom. It develops extremely slowly and does not like regions with winter thaws and spring frosts (for example, the North-West).

I heard that hydrangea can be made to change color. Please tell us how to do it.

If you water the hydrangea with a slightly pink solution of manganese, then the flowers will turn pink, but temporarily. Stop watering, they will turn white again. If you water with a weak 0.1% solution (1 teaspoon per 7 liters of water) ferrous sulfate(or add metal shavings to the soil under the bush), the flowers will be colored in purple, when watering with a weak alum solution - in blue.

But in fact, only the veins of the flower are colored, and the petals themselves remain white. So the color is uneven and, in my opinion, ugly.

Hydrangea is an amazingly beautiful plant that has lush green foliage and multi-colored cap inflorescences. It can be grown both in the garden and in the apartment. With proper care and favorable conditions, the bush will be healthy and beautiful.

However, sometimes flower growers are faced with the fact that hydrangea leaves begin to turn yellow, dry or turn black. Why is this happening? And what should be done if you find such a problem in your plant?

Causes

Basically, the reasons why hydrangea leaves turn yellow are due to mistakes in care or changes in the environment. But sometimes the plant is damaged by pests. Consider possible reasons in more detail.

Lack or excess of light and moisture

If the bush grows in the shade or in an open sunny area, its leaves may begin to turn yellow, brown and dry out. The light regime is very important for the plant - it prefers bright, but diffused lighting.

He will also be comfortable in partial shade from trees or near bushes. The scorching sun burns the leaves, and the lack of light affects both foliage and flowering.

Attention!

If yellowing is due to improper lighting, hydrangeas should either be created suitable conditions, or transplant it to another place.

Although hydrangea is a moisture-loving plant, strong waterlogging primarily affects the leaves. They start to turn yellow and then fall off. If this happens, it is important to reduce the frequency and volume of watering and not flood the plant in the future.

Drafts

Hydrangea is a thermophilic flower, therefore, sudden temperature changes and constant drafts at the site of its planting will lead to yellowing of the leaves and withering of the entire bush.

If the reason for the yellowing is this, the flower should be transplanted to a calm, sunny place. It is important that the soil in the new place is suitable.

When planting a plant, it is very important to choose the right place, think about it in advance.

Low soil acidity

Hydrangea prefers acidic soil, pH 3-6. If it grows in alkaline soil, yellow leaves may begin to appear.

If this is the case, then periodically lemon juice should be added to the water for irrigation in the proportion of 2-3 drops of juice per 1 liter of water.

Also, lemon juice can be replaced with vinegar essence. In this case, the ratio will be: 1 teaspoon of essence per 10 liters of water. Over time, the soil loses its nutrients, the plant also needs to be fertilized.

Lack of nutrients

One of the reasons for the appearance of yellow foliage in a plant may be a lack of fertilizer. From early spring to mid-summer, she needs regular feeding: 2 times a month mineral fertilizers and 1 time organic.

If your hydrangea begins to turn yellow due to a lack of micro and macro elements, feed her with a fertilizer with a high nitrogen content in the spring for active growth of foliage, in summer "Kemira floral" for abundant flowering, in autumn - potassium-phosphorus fertilizers to prepare for the dormant period and the laying of young shoots and peduncles.

Powdery mildew

Yellowing of the leaves can be caused by this disease. You can identify it by the grayish bloom on the back of the leaves. On front side yellow-green spots appear, which turn brown over time and acquire clear boundaries.

Fungicides, for example, Alirin or Fitosporin, will help to cope with the disease. At advanced stages, Tiovit, Skor, Topaz, Jet are used.

Now you know why the leaves of the garden hydrangea turn yellow and what to do with the plant in case of care errors.

Dryness

Possible reasons why hydrangea leaves dry and what to do with the plant:

• Lack of moisture. The plant needs regular, abundant watering, since it loves moisture very much. Due to overdrying of the roots, the leaves begin to dry, especially if the bush grows in a sunny place. The solution to the problem will be timely watering in sufficient quantities and shading the plant;
• Incorrect transplant. If the roots are damaged during transplanting, which absorb water and nutrients, the hydrangea does not grow well, and the tips of the leaves begin to dry out. In this case, the flower needs regular abundant (but not excessive) watering. Once every 10 days, when the soil is moistened, the Zircon preparation is added to the water (diluted according to the instructions). It stimulates root formation. Top dressing is carried out only after the bush begins to grow;
• Low environmental humidity... This often happens in closed spaces, for example, greenhouses. It is important to regularly ventilate and humidify the air around the bush;
• Lack of nutrients. It is especially felt during bud formation and flowering. During this period, fertilizing should be carried out 1 time in 7-10 days.

Blackening

Leaf blackening can be dry and wet, or sluggish. In the first case, along the edges of the leaves, brown spots, which subsequently cause drying and wilting of foliage. The reason why hydrangea leaves turn black and dry may be:

• Sunburn. It is important to protect the plant from the scorching rays of the sun;
• Hard water for irrigation. Regular tap water may contain lime and other impurities. Therefore, before watering it is important to defend it, at least a day. It is better to do this in the sun, so that the water also warms up.

Wet blackening can be easily identified by sluggish, dark leaves. Its reasons may be:

• Drafts or sudden temperature changes;
• Excessive abundant watering;
• Heavy soil that retains moisture and does not allow air to pass through well. Hydrangea prefers light, loose, nutritious soil.

Yellowing

In hydrangea paniculate, with its beautiful pyramidal inflorescences and flowering until the very cold, the leaves can also begin to turn yellow. The reason usually lies in the excess or lack of something., for example:

• Excess or lack of light;
• Waterlogging;
• Lack of nutrients;
• Low acidity of the soil;
• Drafts and sudden temperature changes;
• Diseases such as powdery mildew and ring spot.

To solve the problem of yellowing, it is necessary to regulate the care and create the most favorable conditions for the hydrangea.

At home

Indoor hydrangea is adapted to life in an apartment, therefore, it especially needs to create comfortable conditions for growth and flowering. Sometimes, if the rules of care for the flower are not followed, the leaves may begin to turn yellow and dry.... What could be the reason?

• Damage to the root system during transplantation. In this case, the plant is likely to recover, but it will take time - up to 2 months. You can help him in this by adding Zircon to the water for irrigation every 10 days. It stimulates root formation;
• Insufficient or excessive watering. It is optimal to carry out the next moistening after the top layer of soil in the pot has dried out a little;
• Low air humidity. Hydrangea should be sprayed regularly, especially on hot summer days. It is also important to ensure that the humidity in the room where it is located is above average;
• Lack of nutrients. During the period of active growth and flowering, the potted hydrangea needs regular feeding: 1 time in 7-10 days;
• Excess light. On a southern window without shading, hydrangea can get leaf burn. Optimal location for her - east and west windows.

Knowing about the causes of yellowing, blackening and drying of leaves in hydrangea, you can avoid unnecessary problems. Well, if, nevertheless, trouble has happened, tips on quick help will help in short time restore the splendor of green foliage!

A simple solution

If a magnificent and blooming beauty turns yellow in the garden, she must be rescued. True, this will require knowledge of how much light and moisture is enough, how drafts and soil composition affect, and also what other reasons for such a bush reaction may be. After all, he is amazingly handsome.

And why the lush green foliage of hydrangea begins to change color, you need not just figure it out, but know how to deal with these negative phenomena.

Factors

Why leaves dry and turn yellow in a garden beauty, able to stand in pyramidal inflorescences and green foliage until the very cold, they know experienced gardeners... But additional information will not hurt either them or people who are fond of flower cultivation.

The main reasons are hidden in the following factors:

• moisture (more precisely, excess moisture that poured under the plant);
• lighting (its large amount or lack is reflected in the change in the color of the foliage to yellow);
• lack of nutrients (the size of the bush and the long growing season require a sufficient amount of substances and trace elements, due to which the health of the plant will be preserved);
• improper soil pH (too low acidity can significantly worsen appearance hydrangeas and yellowing of foliage are just the beginning of these changes);
• a temperature regime that does not correspond to the norms for a plant (if there are drafts that a shrub cannot tolerate or sudden changes in temperature, it is then that the leaves of the hydrangea dry out);
• diseases (powdery mildew and ring spot are the most common types that can lead to yellowing and subsequent drying of the leaves).

How to deal with the problem and prevent each of them is indicated in the article below. After all, this long-flowering shrub with pink, blue and even whitish flowers can lose its external beauty if some factors go against the rules of care and cultivation.

Light and moisture

The hydrangea leaves wither and even fall off if the wrong planting site is chosen. This shrub should not grow in the shade or in an overly open space with full access to sunlight. The appearance of yellowness, brown shades on foliage and even its death is a natural result. The scorching sun can burn the leaves.

The lack of light will certainly be visible not only by the changes in foliage, but also by the deteriorated or lack of color on the garden hydrangea.

Only diffused lighting can save the plant from death. If it is not possible to equip a shed or to pull the net from above, then the only way out is to transplant. Partial shade from trees and shrubs, higher than hydrangea, is fine.

This plant is quite hygrophilous, but the lack of watering norms will lead to the fact that it will weaken. What to do if the foliage begins to change color and even fall off - the answer is obvious here. Reducing the regularity, as well as the displacement of irrigation will the best solution until the root system begins to rot.

Nutrients

Some actions should be taken despite the fact that the soil is depleted, it no longer contains nutrients and needed by the plant substances and minerals. Saves the regularity of dressings.

Mineral fertilizers are applied at least 1 time in 15 days, and organic fertilizers - 1 time in 30 days.
Hydrangea can be sluggish if there is a lack of micronutrients and macronutrients. In this case, the rules for caring for the plant will help.

In the spring, the flower should be fed with nitrogen-containing fertilizers.

In the summer, those solutions are selected whose action is aimed at profuse flowering... One of the gardeners' favorite dressings is Kemira Flower. Autumn is the time when young shoots and flower stalks are laid. In order for the plant to prepare well for the dormant period, potassium-phosphorus fertilizers should be used. The color of each leaf on a shrub can indicate a problem.

If the gardener has a store far away, then you can prepare fertilizer yourself at home. One of the main ingredients will be ginger peat. The second is humus from leaves.

It is thanks to him that acidification and saturation of the earth with minerals will occur, where this fertilizer will be applied. Then pine needles and sulfur are mixed. This is not difficult to do. It is only necessary to lightly sprinkle the dug earth with gray. Make only 3 dressings.

One spring when new foliage appears. The other two are in the summer, while the plant blooms and smells literally and figuratively.

To the question of why the leaves of the garden hydrangea turn yellow, there is another answer. This is a lack of iron. The wilting and yellowing associated with this problem is neutralized with acidification. Acid solutions, which are almost always on hand, are fine.

Diluted vinegar and citric or oxalic acid are used. A teaspoon of any of the above substances per 10 liters pure water will save the day.

Burying nails and canning lids, cans and the introduction of a solution of ferovite into the soil will compensate for the lack of iron.

The soil

Garden hydrangea needs acidified soil. As soon as alkalis prevail in the soil, this affects the color of the foliage. The fight against this problem is quite simple.

Lemon juice should be added to the water for irrigation. For 1 liter of pure species, up to 3 drops are enough. You can take a solution of vinegar essence for the same purpose. But here the relationship is different.

You will need one teaspoon of liquid for 10 liters of water.

Temperature violation

Drafts and sudden changes in temperature will definitely negatively affect the flower. This can affect not only the foliage, but also the wilting of the entire shrub.

If it is not possible to create protection for the plant in this place in the form of a decorative hedge, shields or wickerwork, then it must be transplanted. Security, necessary care and the absence of drafts will help the flower to regain strength.
The leaves of the shrub dry up if the air temperature is above 30 degrees Celsius.

After sunset, the hydrangea can regenerate again. But if excessive heat is observed for many days and weeks, the bush cannot be saved - it will begin to dry completely. This does not mean that the flower will die.

However, it will definitely not be able to please with juicy foliage or flowering this year. Hydrangea should be protected from the scorching sun with excessive heat as well as from drafts.

However, it is better to create humidity during hours when the sun is not so aggressive by spraying.

Diseases and the fight against them

Hydrangeas turn black, and not only turn yellow due to powdery mildew. Such a disease is determined in the early stages by a grayish bloom at the bottom of the leaves.

The front side is covered with spots, which turn from yellow-green to brown and even black. Fungicides will help save such a dire situation.

Gardeners use Tiovit, Topaz, Skor, Jet (in advanced cases), Fitosporin and Alirin (in the early stages).

Leaves turn black or turn brown, turn yellow and deform also in case of damage to the plant by such diseases as gray rot, as well as spotting:

• phylloskitous;
• annular;
• septoria;
• ascochitous.

As a result, the foliage not only changes color, but also dries. They fight these microorganisms with the help of Bordeaux liquid, copper sulfate, as well as special preparations purchased in advance, with which it is necessary to process the shrub.

Yellowness and drying on the foliage is a natural reaction if the hydrangea is attacked spider mite... With strong colonization, there are cases when the plant died completely. Insects are afraid of acaricides and insect-acaricides. There are such drugs in almost every store.

If the leaves on the shrub turn black, experienced gardeners immediately look for aphids. It is she who drinks the juices from the plant. And its sticky liquid, the afterbirth, becomes a fertile soil for the growth of a sooty fungus. Tincture of tobacco or insecticides will help save the hydrangea.

True, if an incident occurs, this information will tell gardeners a list of actions with which a successful struggle is possible.

French princess

Hydrangea, or hydrangea (Hydrangea) perennial shrub of the Hydrangivy family, or hydrangea (Hydrangeaceae), common in East Asia, North and South America.

The genus Hortense got its first name in honor of the French princess Hortense.

And already much later, scientists renamed the plant to Hydrangia, derived from the Greek words "hydor" - water and "angeion" - a vessel, which indicates that the plant belongs to moisture-loving. But among gardeners all over the world, the first name stuck - Hortense.

Hydrangeas are perennial, deciduous, large-leaved, ornamental shrubs (sometimes liana-like). Up to 5 stems grow from the lobular roots. Leaves are dark green, opposite, elongated-oval, pointed, dentate at the edges, with clearly protruding veins.

The flowers are collected in large globular inflorescences. Most often flowers of two types - small fruiting, placed in the middle of the inflorescence and marginal - large, sterile, from 4-5 petal sepals, mostly snow-white, blue or pinkish.

The fruit is a 2-5-split box with numerous small seeds.

Large-leaved hydrangea (Hydrangea macrophylla) - ornamental shrub, v open ground the plant can reach 1-2 m in height. Shoots are upright. Leaves are numerous, ovoid, green.

The flowers are collected in large (up to 20 cm in diameter), dense, spherical inflorescences formed at the ends of the shoots. A potted plant produces 3-6 flower caps. On acidic soil flowers are blue, on alkaline - pink of various shades, even white.

There are several varieties of large-leaved hydrangea:

- Japanese variety (Hydrangea macrophylla var. Japonica) - with flat inflorescences, along the edges of which are large sterile flowers, and the middle is occupied by fertile ones.

- changeable variety (Hydrangea macrophylla var. Mutabilis) - spherical inflorescences, consisting of large sterile flowers. Numerous varieties of this variety are widely used in industrial floriculture.

Hydrangea paniculata (Hydrangea paniculata)- a shrub or small tree with large toothed leaves.

Flowers are collected in corymbose or paniculate inflorescences and can be white, pink, red, blue and blue.

This species is frost-resistant and tolerates temperatures of -15 ° C; even if the aboveground part of the plant is destroyed by frost, it will grow back as soon as it gets warmer. Requires annual pruning.

Hydrangea tree (Hydrangea arborescens)- an upright shrub, reaching a height of two meters. Flowering begins in July and continues until the very frost.

Inflorescences are large (up to 25-30 cm), densely covering the bushes. A short pruning of the bushes is required before growth begins.

Frost-resistant plant, tolerates temperatures as low as -20 ° C, quickly recovers in spring.

Stalked hydrangea, or creeping (Hydrangea scandens, petiolaris)- a hardy liana, reaching a height of about 20 m, clinging to the support with numerous aerial roots. The flowers are white, collected in umbellate inflorescences.

Lighting
During the active growing season, Hydrangea does not tolerate direct Sun rays, therefore, it is better to place it in partial shade. But in winter period(from the beginning of January to the formation of buds), on the contrary, it is recommended to place plants in the most illuminated, sunny places.

Temperature
In summer, it is recommended to take the hydrangea out into the fresh air, in a cool place. For the winter, hydrangea sheds its leaves, so it can hibernate in a dark place at a temperature of 4-8 ° C; at the beginning of spring, it should be transferred again to a bright and warm place, where the temperature should not exceed 20 ° C. At temperatures above 20 ° C, the plant sheds its leaves.

Most garden hydrangeas are hardy. They are cut or bent to the ground for the winter, and covered with spruce branches. Under such a shelter, the plant winters well. If the ground part of the hydrangea freezes, then it can be cut off, and then the plant will bloom next year.

Air humidity
Hydrangeas prefer high humidity. To do this, it is recommended to regularly spray the leaves, you can place the pot in a tray with wet expanded clay or moss, but the bottom of the pot should not touch the water.

Watering
In the spring and summer, hydrangea prefers abundant watering, as the topsoil dries out. From autumn, watering is gradually reduced. In winter, hydrangea is watered occasionally, but the soil is not allowed to completely dry out. When leaves appear, watering is gradually increased.

Fertilizer
With the appearance of buds, the hydrangea begins to be fed with complex fertilizer for flowering plants 2 times a month.

Dormant period
In winter, hydrangea has a dormant period. At this time, she sheds leaves. Store the pots at this time in dry, cool rooms, you can in dark ones. The rest period lasts 2-2.5 months.

Pruning
After a dormant period, it is necessary to prune weak and elongated shoots, leaving 2-6 eyes on the branch. This promotes good growth of new, stronger shoots, increased flowering.

Transfer
Hydrangea is transplanted annually. At the same time, one must be careful with the choice of soil, because for white, pink and red varieties, soil with low acidity is needed, and for blue varieties - with high soil.

Reproduction
Hydrangeas are propagated mainly by cuttings, less often by seeds, dividing bushes, offspring and layering, grafting. For cuttings in March, take young lower shoots with leaves 7-8 cm long with 2-3 internodes. The leaf blades are shortened by a third or half.

Attention!

The two lower leaves must be removed, the cut must be straight, 3-4 mm below the knot. They are planted at a distance of 4-5 cm from each other in deep bowls, deepening into the sand by 1.5-2 cm. It is not recommended to cover the cuttings with glass, as they can rot. In the first week, they are sprayed 3-4 times a day, then 1-2 times.

After 5-6 weeks, well-rooted cuttings with a lump of earth are planted in 7-9 cm pots. In May, the cuttings are pinched for bushiness.

Cutted in March, hydrangeas will bloom in May - June next year... One-year-old plants form 1-3 inflorescences.

Diseases and pests
Spider mite. It affects the leaves from the underside, causing them to turn yellow and marbled, then dry and fall off. The mite covers the underside of the leaf with a brown spider web.
Preparations for struggle: aktara, actellik, fitoverm, thiophos.

Downy mildew. It affects the leaves and stems of hydrangeas. Its first signs are the appearance on the leaves of oily, later yellowing spots, gradually darkening and increasing in size. A yellowish bloom appears on the bottom of the leaves; the same bloom can be found on young stems.

The development of the disease is facilitated by a temperature of 18-20 ° C and high air humidity.
Control measures: treatment of affected plants with copper soap liquid (150 g of green soap, 15 g of copper sulfate per 10 liters of water).

This liquid, harmless to plants, and its use in the early stages of development helps to completely get rid of the disease.

Chlorosis. A sign of chlorosis is the clarification of the leaves, only the veins on them remain dark. Plants growing on soils with a significant amount of lime are more susceptible to chlorosis.

An excess of humus in the soil also leads to chlorosis.

Control measures: pour 2-3 times with a solution of potassium nitrate at the rate of 40 g per 10 l of water and three days later - with a solution of ferrous sulfate, also 40 g per 10 l of water.

In conditions closed ground when forcing plants, hydrangea can be affected by green leaf aphids.
Control measures: a good means of its destruction is two-time spraying of plants with anabazine sulfate solution. To do this, 15-20 g of anabazine sulfate is dissolved in 10 liters of water.

With an excess of light, light spots appear on the leaves.
With insufficient watering and dry air, the tips of the leaves dry out.
With a lack of nutrition, plants develop poorly and do not bloom.

Useful information

Hydrangea is a wonderful plant that is often grown by flower growers, both in the garden and at home. The plant blooms very beautifully and fits perfectly into the home interior.

Hydrangea care is quite simple, since it is not whimsical to the conditions of detention. But sometimes hydrangea leaves turn yellow and dry.

Why this is happening, and what to do in a similar situation, we will try to tell you in this article.

Causes

Why did hydrangea leaves start turning yellow, what should I do? There can be several reasons for yellowing, but this usually happens due to inadequate flower care. In this case, it is necessary to reconsider the correctness of flower care.

Hydrangea leaves can also turn yellow due to errors such as:

1. Excessive humidity. Home hydrangea loves moisture very much, but if you water it strongly, then the flower can only be poured, and this is quite detrimental to the leaves, which will turn yellow and fall off as a result.
2. Lack of warmth. Hydrangea very poorly tolerates drafts and low temperature regime... In such conditions, the leaves of the plant turn yellow and dry.
3. Lack of nutrients. Home hydrangea for good flowering should receive the necessary micro and macro elements.
4. Lack of lighting. In order for a flower to grow and develop normally, it needs good lighting... Hydrangea prefers bright and diffused light... But only direct sunlight should not fall on the plant, otherwise the leaves may get sunburn.
5. Lack of fertilization during the period of active growth of the flower. If you do not apply top dressing, the leaves turn yellow and dry.

Why have home hydrangea leaves dry and what to do? Home flower needs nutrients, and in particular during the flowering period. With a lack of useful elements, the formation of inflorescences will be defective, and the tips of the leaves will turn yellow. This happens very often when the earth is deficient in nitrogen and iron.

Diseases

Why do hydrangea leaves turn black? Sometimes it happens that the care of the plant is carried out correctly, but the leaves still turn yellow, which means that the reason lies in something else. In some cases, hydrangea leaves turn yellow and dry due to disease. Although the plant is quite resistant to various infections, but in certain cases it can be afflicted with diseases.

The most common hydrangea disease is ring spot. When a disease affects a flower, its leaves not only turn yellow, but also become deformed.

Besides the annular spot, indoor flower other diseases can also attack:

• powdery mildew;
• chlorosis;
• white rot.

Powdery mildew

The disease manifests itself in the form of oily spots, which after a while turn black. The disease occurs due to high humidity. To get rid of powdery mildew, you need to treat the flower with soapy water, to which they add copper sulfate... Such treatment must be performed in the early stages of the disease.

Chlorosis

Why does chlorosis affect hydrangeas? The disease most often occurs due to improper watering.

Chlorosis occurs when a plant is watered with cold tap water, where a large proportion of lime is present. With this disease, the leaf turns yellow and dries.

In some cases, chlorosis leads to the death of the plant. Treatment of a flower from chlorosis includes spraying the plant with special preparations: Ferovit, Agricol, Ferrilene.

White rot

This disease is manifested by decay of the roots. With such a disease, the flower does not receive useful substances, then it begins to darken and dies. To eliminate the disease, the plant must be treated with a chemical such as Fitosporin or other fungicides. If you do not want your hydrangea to be affected by various diseases, then the care of the plant must be correct.

Treating diseased leaves

When the edges of the leaves dry, you need to react urgently, otherwise the plant may die. First, you should determine the cause, and only then choose a method of treatment.

The main methods of treatment:

• with an excess of moisture - it is necessary to pause or water the watering for a while, but not so often;
• if there is a lack of heat, the hydrangea should be removed from drafts and placed in a warmer room;
• if not enough nutrients- you need to start feeding the flower. Experienced florists it is recommended to apply fertilizer to the pot when watering with water; you also need to use soft and settled water for watering.

At insufficient quantity iron in the earth, the acidity of the earth should be renewed. In this case, vinegar essence must be added to the soil. Prepare the solution as follows: take 1 teaspoon of the essence and pour it into 10 liters of water. By the way, vinegar can be replaced oxalic acid... In addition, to restore the acidity of the earth, a ferovit solution should be used.

In case of viral diseases, diseased leaves must be removed, and the flower must be treated with fungicides. Quite often, professionals use Bordeaux liquid against diseases (1%). If you properly care for the hydrangea, the edges of the leaves will not turn yellow and dry.

Prophylaxis

In order to prevent the appearance of yellowing of the leaves, it is recommended to adhere to some tips:

1. It is required to correctly organize the irrigation regime. You don't need to flood the flower too much, but dry it too.
2. Use soft and settled water for irrigation.
3. The plant is best placed in a warm room.
4. Keep the pot away from direct sunlight as the edges of the leaves can dry out.
5. From time to time, you need to feed the hydrangea (mainly during the flowering period).

In addition, you can sometimes spray the flower with various preparations for microbes. If you adhere to these recommendations, then you will be able to avoid the appearance yellow leaves home hydrangea, and maintain its excellent appearance for a long time.
