Causes of yellowing

If you see that the hydrangea has begun to turn yellow, then the first thing that comes to mind is that somewhere an error has crept in in the care or the plant is missing something. Therefore, first of all, you need to evaluate the correctness of care, and only then look for other reasons why a yellow leaf appeared on the plant.

Hydrangea leaves turn yellow due to the following mistakes made when caring for it:

• you filled the flower. Home hydrangea is a very moisture-loving plant. But even it can be flooded if watering is done too often. It is the leaves that will react first to waterlogging, which will turn yellow and fall off;
• lack of warm. This indoor flower does not like drafts and low temperatures. When a plant enters such an environment, the first signal of unsuitable conditions of detention will be a yellow leaf that appears;
• a lack of nutrients. Even for a room hydrangea that grows in a pot, it is necessary to ensure that it receives the optimal set of micro and macro elements;
• lack of sunlight. For normal growth and development of a flower, it is necessary to observe a certain light regime. It is important for both the health of the hydrangea and beautiful flowering. But remember that the light should be diffused, not direct. Otherwise, those who received sunburn. It is manifested by the fact that the leaves are stained in Brown color and dry;
• top dressing during flowering and stem formation. If this is not done, after a while the first yellow leaf will appear on the stem.

It is worth dwelling on the lack of nutrients in more detail. During the flowering period, the plant requires the maximum amount of nutrients. And even a small lack of them can lead to inadequate formation of inflorescences, and also cause the leaves to turn yellow. This usually indicates that the soil lacks iron and nitrogen.

If the care of the flower turned out to be correct, but the leaf is still yellow, you need to look for the cause elsewhere. Sometimes the leaves of the hydrangea turn yellow and dry due to illness. Despite the sufficient resistance of hydrangea to various types infections, in certain situations it can be attacked by viruses and fungi. Why such situations arise is quite easy to answer. The whole reason here lies again in improper care behind a flower.

For room hydrangea, not so many diseases are characteristic, and only some of them can cause the appearance yellow leaves. For example, the most common reason that leaves turn yellow is viral disease like ring spot. In this case, the sheet not only turns yellow, but also deforms. It is by the deformation of the foliage of the plate that it can be determined that the cause here is in the virus.

In addition to the ring spot, domestic hydrangea can be affected by axochitose spot. Castings also turn yellow here. But they also dry out pretty quickly, die off and fall off. Room hydrangea is also characterized by such an ailment as chlorosis. The reason for its occurrence is a violation of the technique of watering the plant. A flower can pick up chlorosis after it was poured with hard tap water, in which there was a large percentage of lime content.

As a result of the accumulation of lime in the soil, it leads to alkalization of the soil. The infected leaf will turn yellow and dry. They dry out due to the fact that the plant does not have the opportunity to fully eat. Such a situation, if it can lead to the complete death of the flower. As you can see, there are quite a few reasons that can lead to the fact that the leaves began to turn yellow on the hydrangea. But often the reason lies in the wrong care. Therefore, you need to be very careful about this. indoor flower and care for him.

How to cure diseased leaves

When the leaves turn yellow, urgent measures must be taken to treat the hydrangea, otherwise the flower may die. First of all, you need to find out the cause and already push away from it in choosing a method of treatment.

Let's consider some of them:

• in case of waterlogging - it is necessary to normalize the water regime by reducing the number of irrigations;
• with a lack of heat - rearrange the flower from the path of drafts and into a more heated room;
• when identifying the cause of a lack of nutrients, start feeding. Usually, fertilizers are applied to the pot during watering along with water. You should also use only soft water that has settled well.

Separately, it is worth noting that if there is a lack of iron in the soil, then it is necessary to restore the acidity of the soil. To do this, you need to add a solution of vinegar essence to the soil. It is prepared by adding 1 tsp to 10 liters of water. essences. Please note that instead of vinegar, you can use oxalic or citric acid. In addition, a special ferovit solution can be used to restore soil pH.

But in a situation where the resumption of proper care will no longer give desired result, the flower will have diseases of a viral or fungal nature. Although proper care will help improve the condition of the plant, it will not be enough. Here, the infected leaf must be removed, and the hydrangea itself must be treated with special fungicidal preparations. Often used to fight disease Bordeaux mixture(1% solution).

Measures to combat chlorosis include transplanting the flower into a new pot. Its further watering is carried out only with softened water.

Disease prevention

Prevention has always been everywhere the best remedy fight against various diseases and pathologies. This applies not only to the animal, but also flora. Therefore, if you want to prevent the appearance of yellow leaves on hydrangeas, follow these recommendations:

• keep the optimal water regime. Do not heavily flood or dry the plant;
• watering only with soft settled water;
• put the flower in warm room without drafts;
• avoid direct sunlight on the leaves;
• do periodic top dressing (especially during the flowering period).

You can also sometimes treat the flower with agents against microbes and viruses. By following these recommendations, you can prevent the appearance of yellow leaves on a room hydrangea and preserve its beauty for many years.

Video "Why do the leaves on plants turn yellow?"

Every self-respecting gardener has repeatedly asked himself the question: why do plants turn yellow leaves? To answer it as accurately as possible, we advise you to watch the following video clip.

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 up?

There can be many reasons, among them:

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

Hydrangea, leaves dry, what to do?

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

In this case, pour the flower with acidified water (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 will turn yellow with a lack of iron with nitrogen. This often happens during active growth(spring), so don't forget to fertilize.

This should be done starting in February once every two weeks. In winter, the plant does not bloom, so root feeding is not needed at this time of the year.

Hydrangea, the tips of the leaves 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. In order for the plant to please you with a riot of flowers at the time of flowering, which can be from one to seven on one bush, it needs water in a timely manner.

Wait to upper layer the soil in the pot has dried up and water again. Watering should be separated warm water, not tough! Hard water can cause disease - chlorosis. The signal will be yellowed leaves with green veins.

Also, do not forget to spray the leaves and flowers with water and maintain the humidity in the room. For hydrangea, these two factors must be properly balanced – air is humid, 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 pot. small size and place it on a window on the north or east side of the room. You need to leave 3-4 of the strongest sprouts, and remove the rest of the password. After flowering, in July, the hydrangea is pruned. If not cut in time, the flower may not bloom next year!

Hydrangea, leaves dry, reasons.

Another reason that hydrangea leaves dry is considered to be improper lighting. Hydrangea categorically does not like direct sunlight, so it has no place on the windowsill! It is better to put it on a 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.

Hydrangea home, leaves dry after transplantation.

Another important process in the care of hydrangea, its transplantation is considered, since improper transplantation will cause the leaves and flowers of the plant to dry out. Home hydrangea grows for four years, then you plant a new one.

In order to transplant hydrangeas, take a wide pot, this is because the roots of hydrangeas 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. Therefore, dig, keeping an earthen ball around the roots.

Hydrangeas do not like direct sunlight, they should be planted in partial shade or create an artificial shadow in the midday hours.

Do not water them directly from the tap. It is necessary to let the water not only stand for at least a day, but also let it warm up.

Sluggish, it is also a wet blackening - the foliage darkens, goes limp. This happens due to:
Excessive moisture
Landing in heavy soil;
sudden changes in temperature or too cold summers.

To improve the bush, watering should be restored. In case of unsuitable soil, only transplanting into more appropriate place. With unfavorable weather conditions Mulching will help protect the root system.

Quite often, hydrangeas have leaves like fade, become pale green, almost yellow, the veins on them remain saturated green. The disease is called chlorosis, it is caused by a lack of iron. Either it is not in sufficient quantity in the soil, or the flower itself, due to some of its characteristics, is not able to fully absorb it.

In addition to a change in color, signs of chlorosis may be a decrease in leaf size, twisting, buds may also dry or young shoots may fall off.

To avoid this disease, hydrangeas need to be fed only with special fertilizers that prevent the earth from leaching. You can use coniferous waste as mulch or add coffee to sleep.
Many gardeners for watering slightly acidify the water.

If the plant is still sick, the treatment is carried out with iron chelates (special preparations Ferovit, Antichlorosis, etc.). Solutions are used according to the instructions. Best result gives usually spraying of leaves.

The appearance of small (from 2 to 6 millimeters) dark brown spots on the green parts of the plant means infection with septoria. The disease spreads rapidly and is capable of short time destroy the adult hydrangea. To combat the misfortune, there are special preparations, but as a preventive measure in the spring, all the bushes must be sprayed with Bordeaux liquid.

The parts affected by septoria are cut off, capturing healthy areas, and burned. Sections are disinfected and covered with garden pitch.

If the bushes are planted too densely or there is an excess of nitrogen in the soil, brown-rusty spots appear on the leaves. It's rust fungal disease. For recovery, they are treated with copper-containing preparations.

At the mention of hydrangea, some summer residents imagine voluminous snow-white spherical inflorescences, others imagine magnificent velvety bluish flowers in a semi-shady area. Someone sees small tree plants which are covered with paniculate flowers. But hydrangeas sometimes turn yellow leaves, what should summer residents do in such a situation?

Features of growing hydrangeas

When growing hydrangeas, focus on:

1. Plant love for water. In Latin, Hydrangea means "vessel filled with water."
2. The acidity level of the soil is pH 5.0. For hydrangeas, acidic soil is preferable. The content of lime in the soil in in large numbers not to the liking of the plant. tree view more tolerant, but do not abuse it to get good flowering.
3. Loose fertile soil and regular fertilization - affect the development of hydrangeas.
4. Varieties that bloom on the shoots of the current year - the bushes are pruned only in the absence of vegetation.
5. To the location of the hydrangea. In areas with hot summers, the water-loving hydrangea likes partial shade. Only a few varieties bloom in a sunny place, however, with periodic and abundant watering in drought conditions. Punctures in the cultivation of hydrangeas are often associated with an unfavorable soil reaction for the culture. The plant needs an acidic microenvironment. In the central zone of Russia, petiolate and large-leaved hydrangeas also grow.
6. Crown shaping. To obtain leafy and flowering shrub the culture pinch the apical shoots.
7. Temperature regime. Hydrangea is successfully grown indoors at a temperature of + 12 ... + 18 ° С. Prevent freezing of the bush: hydrangeas are removed in time for storage in the fall. Take it to a dark and cool place. A week's stay in the dark will affect the fall of frost-bitten foliage. Later, the hydrangea is stored in the cellar until spring.
8. Apical buds. It is important not to damage during storage - they provide luxurious flowering. If the soil in the pot dries up, a single watering during the storage period is enough.

Hydrangea leaves turn yellow: causes

A change in the color of the leaves signals an unhealthy hydrangea. There are many factors that explain why hydrangea leaves turn yellow.

Features of growing hydrangeas

Nutrient deficiency

Lack of fertilizer provokes the yellowness of hydrangea leaves. With the advent of spring and until the height of the summer season, the plant needs systematic feeding: 2 times a month mineral supplements and 1 time - organic.

It is important for summer residents to figure out if the leaves of the hydrangea brighten than to feed. The lack of macro- and microelements is eliminated by applying nitrogen-containing dressings in the spring; in the summer, Kemira flower is used for lush flowering. Phosphorus-potassium fertilizers are usually applied in the fall to prepare the hydrangea for a dormant period and the formation of young shoots and flower buds.

Nutrient deficiency is felt acutely in the budding phase. At this stage garden hydrangea feed 1 time per week. |

Wrong watering

Hydrangea is classified as a moisture-loving crop. She is provided with the frequency of watering, regardless of the variety. They do not allow the soil to dry out - the hydrangea does not tolerate heat, the green leaves turn yellowish and curl. When dry, water 2 times a week. At least a bucket of liquid is poured under an adult.

When in summer season it sometimes rains for a short time, and peat mulch has been added to the near-trunk zone of the hydrangea, it is possible to limit the monthly watering to 1 or 2 times.

Wrong watering

Indoor hydrangea is moistened when the top layer of the earth dries up in a flower pot. At low humidity indoor air dry the green leaves of the plant. Therefore, the culture must be constantly sprayed, especially in the heat, and monitor the humidity at the location of the flower. It must be above average.

An excess of moisture is no less dangerous for the plant. Failure to comply with the norms in watering causes lethargy and weakness of the plant. Why the hydrangea leaves suddenly turned yellow and what to do - the solution is obvious. You will need to reduce regular watering and their volume to avoid root rot.

Low acidity of the soil

Outdoor hydrangea likes acidic soil with a pH level of 3-6. When the culture grows in alkaline soil, at times the green foliage turns yellow.

They fight the problem by acidifying the water with lemon juice: 2-3 drops per 1 liter of liquid. Acetic essence is suitable, which will require 1 tsp. for a 10 liter bucket of water.

Diseases

If a light leaves in hydrangea, the plant suffers from phytodisease. About defeat powdery mildew testifies gray coating on the reverse side of the leaf. Outside, green-yellow spots are formed, which after a certain time turn brown and take on a clear outline.

Fungicides resist the disease:

• Fitosporin and Alirin (at the beginning of the disease);
• Jet and Skor;
• Topaz and Thiovit.

When the green leaves do not please with the saturation of the color, they turn into black or brownish, turn yellow and change, the hydrangea suffers from gray rot or spotting:

• ring and ascochitosis;
• septoria and phylloscytosis.

As a result, the leaves change color, dry out and fall off. Fight pathogens with a Bordeaux mixture blue vitriol, other pesticides that are used to treat hydrangea bushes.

Other reasons

Among other reasons why hydrangea leaves turn white, there are:

1. Incorrect transplant. When the roots are injured, the plant is different poor growth and the dried edge of the leaves. The culture needs abundant, however, not excessive watering. When irrigating the land every one and a half weeks, a Zircon root formation stimulator is added to the liquid. Top dressing is carried out after the beginning of the development of the shrub.
2. Too much light. On the south side of the window sill, if there is no shade, the culture is able to burn the foliage. Ideal for hydrangea windows located on the west or east side of the house.
3. drafts. Hydrangea belongs to heat-loving crops, does not tolerate sharp temperature fluctuations and through blowing at the landing site. So that the leaf plates do not change shade and do not fade, you will need to transplant the hydrangea shrub to a site protected from the winds. The main thing is that the soil matches, and there is enough sun.

Prevention

How to care for a plant so that it is not weak? Preventive measures- the best remedy in resisting various phyto-diseases of flora and fauna.

To prevent change green leaves colors follow the following rules:

• adhere to the water regime: they try not to flood or dry the hydrangea;
• water the shrub with soft, settled water;
• expose the plant only in a warm room where there are no drafts;
• evade the effects of the sun's rays on the foliage of hydrangeas;
• so that the leaves turn lush green, summer residents remember about periodic recharges.
• carry out antimicrobial and antiviral treatments.

How to reanimate with yellowing foliage

When changing the greenish color of the leaves to yellowish, it will be necessary to take adequate measures to heal the hydrangea, otherwise the shrub will die. It is useful to establish the causes of the disease and choose the appropriate methods of therapy.

When the bush dries up, they try to restore it. When hydrangeas grow in the garden with the advent of spring, frozen areas are cut out. When the culture is affected by rot, pruning will have to be done 1 cm below the infected zone. The place of cutting will certainly be sprinkled with ash or activated carbon. The secateurs after the procedure must be disinfected. The bush is treated with fungicides, depending on the phytodisease.

How to revive hydrangea

To reanimate a hydrangea from a vase, from where it is necessary to extract a flower, you need to cut it obliquely lower part and immerse the plant in a steep pitch for 3-5 minutes. When the air bubbles stop coming out of the stem, the hydrangea is taken out of the liquid, the part that was in boiling water is cut off, and the plant is placed in cold water. Manipulation will add charm and elegance to the flower.

Often hydrangea awakens from hibernation weak, with growth, they notice crushed foliage with veins like steel. The lack of nitrogen is replenished by foliar spraying of the crown. ammonia. Top dressing is prepared from 2 tbsp. l. ammonia, which is dissolved in 10 liters of water. Enough 1-2 procedures.

If the leaves of the plant turn yellow from chlorosis, the hydrangea is treated iron vitriol, as well as iron sulphate at the rate of 5 g of funds per 1 liter of liquid.

It will take transplanting hydrangeas into a new container and watering with softened water.

Folk recipes for hydrangea growth

Infected fragments are deleted. When the hydrangea is completely sick, the bush will have to be replaced with a new purchase. If the plant can be saved, the roots are soaked in a solution of potassium permanganate.

The substrate is thrown out of the pot, the dishes are washed with a disinfectant. Then they are filled with fresh soil, having previously placed drainage on the bottom of the container. Moisture-loving hydrangea does not tolerate stagnant moisture, which threatens to damage the roots.

To create a culture of the required conditions, attention is paid to the features of care. The roots of the plant lie below the surface of the soil. When planted in a very deep pot, the hydrangea will not grow until the soil in the container is filled with roots. When growing a flower bush, choose a small, durable earthen vessel.

Indoor hydrangea prefers coolness, in the summer they are placed in an open space, in partial shade. AT winter time it is suitable to keep in a cool room with a temperature in the range of + 5 ... + 10 ° С. When there is no suitable place in the house, the branches are cut after flowering, and the container is hidden under the bath. In the spring, the flower is taken out of the "dungeon", watered and fertilized.

On a note. Root feeding of hydrangeas is carried out only on moist soil, so as not to burn the roots.

In the spring, the plant is fed:

• mullein (1:10);
• chicken manure (1:14).

When preparing a solution, organic raw materials are poured with water and infused for 24 hours. They spend 5 liters per 1 adult culture, 1-2 liters are enough for young seedlings.

For bright and lush flowering in the summer season use:

• herbal infusions (thistle, nettle, dandelion, celandine);
• yeast feed or breadcrumbs.

Top dressing with bread is important for the health of hydrangea and lettuce leaves of the plant.

For her you will need:

• 10 liters of water;
• 1000 crackers;
• 100 gram pack of yeast;
• 1 st. l. granulated sugar.

The mixture is insisted in warmth for a day. 5 liters of fermented mass are poured under the shrub.

Attention! The bread mass is covered with a layer of soil so that the bread aroma does not attract birds.

To enrich the soil with microelements and protect against diseases, dilute 500 ml in 10 liters of liquid:

• serum;
• curdled milk;
• kefir.

In the fight against aphids, shrubs are sprayed with soapy water or garlic tincture (200 g per 10 liters of water).

In order for the hydrangea to please the owners with luxurious flowering and health, it is important to provide proper care and treat diseases in a timely manner.

Hydrangea is loved by many flower growers and it is not surprising, because the large caps of its inflorescences, flaunting rare pastel shades, look very impressive during flowering, which lasts quite a long time. This houseplant is relatively resistant to diseases and pests.

Nevertheless, flower growers still have problems with it, associated with violation of growing conditions. For example, it happens that the tips of the leaves begin to dry out in hydrangeas. And more and more. But the leaves are an important organ of the plant, without them it dies.

Why indoor hydrangea dries

Large-leaved hydrangea, due to its active development and garden origin after flowering, is recommended to be transplanted annually into new soil, with the obligatory loosening of the root ball. Very often, as a result of a transplant, the tips of the leaves begin to dry in a perennial. There can be many reasons for this phenomenon, but in most cases they are:

1. Injury to the root hairs during transplantation, which is why the bush simply “overdoes”.

2. Wrong choice of soil mixture.

3. The wrong size pot.

In addition, there are several other reasons not related to plant transplantation, due to which the leaves begin to dry out. These include:

1. Insufficient watering and spraying.

2. Dry indoor air.

3. Lack of micronutrients in the soil.

4. Wrong lighting.

It is worth considering each of the reasons separately to find out why the room hydrangea leaves dry out.

Transplanting is serious business.

If the dryness of the leaves was the result of an inaccurate flower transplant (unfortunately, no one is safe from this), then it is worth considering that this condition can last one or even two months until the bush fully restores strength and health.

Even in the process of transshipment of an earthen clod, it is not possible to avoid a violation of the formed root system. Meanwhile, small roots and hairs, entangling the soil in a dense network, play important role in moisture absorption. Their damage leads to a temporary malnutrition of the plant. It can be revived by effective and efficient watering with the addition of Zircon once a week.

Incorrectly selected soil can also cause a similar phenomenon. As you know, this culture requires acidic soil. Therefore, it is impossible to plant hydrangea in humus. AT pure form it does not give the soil acidity necessary for this plant. When planted in neutral or alkaline soil, flower development slows down.

No less important when transplanting is the choice of a new pot. It should be wide, but shallow, because root system does not grow in depth, but grows mainly in width. The new pot should have a diameter of 1.5 times the previous capacity. But when planting a bush in light soil, you do not need to get involved in increasing the volume of the pot, otherwise in the summer the plant will need more frequent watering.

Providing watering and air humidity

Dry leaf tips may be a reaction to insufficient soil moisture. Hydrangea loves moisture, and therefore timely watering is very important to her. Even a short-term lack of moisture can lead to the fact that her leaves begin to dry out.

The situation will be aggravated even more if the flower pot is on the windowsill under the scorching sun. You can reanimate the plant by placing it in a shady place, without depriving it of sunlight, and providing abundant watering and additional spraying.

In the same way, this beautiful moisture-loving flower reacts to too dry air in the room where it is located. It is worth measuring the level of humidity in the room.

To prevent this problem, constant spraying or the installation of a simple humidifier in the form of a tray or saucer with wet stones and moss will be required.

How important is it to feed and choose a good place

Another cause of drying leaves is a lack of nutrients in the soil. The fact is that during the flowering period, the plant needs top dressing, which should be carried out weekly by any complex fertilizer intended for flower crops. But it is worth considering that hydrangea reacts negatively to high doses. mineral fertilizers from which its leaves turn yellow. At the end of flowering, top dressing is gradually reduced.

Indoor hydrangea must be properly placed indoors. Despite the fact that it is a light-loving flower, from an excess of sunlight, its dark green foliage is usually covered with light spots. The best option location flower pot are the sills of the eastern and western windows. In addition, care should be taken that the foliage does not touch window glass, otherwise, due to the resulting burns, the tips of the leaves will begin to dry.

It is very important to recognize the problem in time so that the assistance provided is timely and correct. Only in this case will it be possible to save the indoor hydrangea and admire its luxurious flowering for a long time.
