Why not grow hydrangea, the main disease of the flower

A lush hydrangea bush can decorate any summer cottage or window sill, but all this beauty can sometimes be spoiled by diseases. In the garden and indoor flower diseases do not practically differ, therefore, below we will study in detail how to cure hydrangea, regardless of its type and place of planting.

How to cure chlorosis

Garden hydrangea can be affected by many diseases, and chlorosis is one of the most ferocious. Because of this disease, the leaves of the plant become pale or turn yellow, while the veins on them darken greatly. If you do not pay attention to these symptoms in time, over time the plant will lose its beauty, since all these signs are evidence of malnutrition, in particular iron deficiency.

Therefore, wherever you plant your hydrangea, regularly feed it with special fertilizers containing iron elements. Water the flower should be soft water collected during the rain. Also, do not plant garden hydrangea in a soil enriched with lime, and try to use the humus as a minimum to feed it.

But if the disease has already manifested itself, it is recommended that hydrangea bushes be sprayed with one of the following drugs:

• Agricol;
• Iron Chelate;
• Anti-chlorosis;
• Ferovit;
• Ferrylene;
• Micro Fe;
• Brexil.

In addition to spraying, these drugs can also be applied at the root of the plant, but only in very small doses. Also, a solution made of 40 g of potassium nitrate and the same amount of ferrous sulfate diluted in 10-15 liters of water is used against hydrangea chlorosis. This solution can be used to water the flowers in the flowerpots and in the flowerbed: 2-3 times we feed with saltpeter, then with iron sulfate until the traces of the disease disappear.

Gray rot: methods of struggle

Gray decay is no less dangerous for hydrangea, as the affected stalks and flowers become very soft, watery, which eventually dies. At the same time, lesions can appear on the leaves and stems by dots, which in hot weather dry up and spill out, leaving behind them unsightly holes.If the weather is wet, then the disease will spread rapidly, and “cotton wool” will also form on top of the affected areas.

It is very difficult to get rid of gray rot on a garden hydrangea, as this disease is common to almost all garden plants, and hydrangea can be infected again. However, if you regularly remove and burn all the affected areas and spray the flower with “Skor”, “Chistotsvet” or “Fundazol”, then soon all the symptoms will disappear.

Flower cancer: how to treat a disease

This disease began to occur in the beds of hydrangea fans not so long ago, as the European flower crayfish arrived at our summer cottages along with imported varieties. Despite this, the cancer is a fairly great danger for hydrangea and is manifested by brown spots, under which ulcers form on the stems. The longer you don’t pay attention to this disease, the more it will progress - the sores will deepen, the stems will start to die off first in places, and then completely.The result is one - hydrangea can completely dry out.

There can be a lot of reasons for the defeat of bushes with cancer: infected planting material, poor feeding, due to hail-damaged areas, when bushes are too thick. To cope with cancer, it is necessary to apply a whole range of measures:

1. At the first signs of illness, try to remove all the affected areas on the flower and burn them.
2. If the cancer appeared on the roots - the bush must be completely removed and burned.
3. Provide flowers with all the necessary mineral and organic elements, which will increase the resistance of hydrangeas to various diseases.

Mealy dew

When yellow-green spots appear on the leaves of the hydrangea, which become more and more dark over time and acquire clear contours, you should prepare for the fight against such a disease as powdery mildewsince all these signs are her symptoms. It is clear that such leaves will not be able to survive on the stems for a long time and will soon begin to fall off.

If powdery mildew fungus will strike young shoots of hydrangea, they are deformed and will not be able to develop enough to survive the next winter.At the initial stages of the development of the disease, hydrangea bushes are recommended to be sprayed with fungicides, which are represented by the preparations "Alirin-B" and "Fitosporin-M".

In case powdery mildew has conquered most of the plant, spraying with such preparations will help save the flower:

• Pure color;
• Tiovit Jet;
• Soon;
• Topaz;
• Strobe;
• Cumulus

Leaf Deformation: How to Cure Ring Spills

Ring spots, which lead to deformation of the leaves of a plant, are the most common viral disease of this flower. The disease develops gradually: at first, small lesions in the form of spots with fuzzy contours of the ring appear on the leaves of the hydrangea, then they dry them and force them to deform, making them asymmetric.

When the ring spot strongly affects the flower, it may not even bloom, or the flowering will be very weak.Unfortunately, it is impossible to get rid of this disease. The only measure that will help you prevent it is to carefully select seedlings for your flower bed.

Stem Nematode

Among the diseases of room hydrangea, as well as her garden relative, there is also a stem nematode. The nematode is a very small worms, which are particularly intensively developed in a humid environment, affecting not only the stems, but also the roots of the plant, as well as their leaves. Under the influence of nematodes, the normal development of the plant stops, and over time it may die.

Since nematode larvae are very small, it is not difficult for them to wade through the roots to the stems and buds of flowers, which they severely damage. This parasite is also capable of leaving behind poisonous substances that stop the growth of hydrangea shoots and cause unsightly bloating on its stems.

If your hydrangea is also struck by stem nematodes, it is recommended to destroy the plant, since it is almost impossible to cope with them, but they can quickly move to other plants, including cultivated ones. The fact is that nematodes can spread with the soil, through pots, and even with water droplets that drain from the plant after watering, and by using inventory during processing.

White Sclerocial Rot

This is a fungal disease that is often found on hydrangeas. It is very difficult to cope with it, since its pathogens - sclerotia - are able to preserve their vital activity in plant residues forgotten on the ground after harvesting.

This kind of rot first acts on the root system of the hydrangea, leading to its rotting and stopping the supply of nutrients to the stems of the flower, which eventually turns brown and dries out completely. At the same time, if the disease has struck young stems, they will not just begin to wither and grow brown, but they will also begin to progress to rot, over which a white cotton-like patina forms. It is impossible to allow the formation of this plaque, since sclerotia will form under it, which can completely infect your entire flower garden.

Thus, it is better to immediately remove the hydrangea affected by white sclerotsial rot from the flower bed, thereby stopping the development of the disease.

Prevention of hydrangea diseases

Indoor flower hydrangea loves well-moistened soil, so it needs to provide frequent watering. If you forget about the hydrangea for a while, it will still be able to come to life after resuming the supply of moisture. However, it is not recommended to experiment with a flower, as this will greatly weaken it and make it susceptible to diseases.

For normal growth of hydrangea, you should also provide a sufficient amount of light, although you should not put a pot with it on the south window. As for the temperature, in too warm a room and with abundant watering the flower can start to get rid of the leaves, besides the first signs of downy mildew can appear on the plant. Growing up in a draft can lead to the same result.

For the prevention of the above-listed diseases of hydrangea, it is recommended to regularly spray it with a solution of copper sulfate (15 liters of substance per 10 liters of water), as well as regularly transplant and trim. It is especially important to remove from the bushes the already damaged stems and leaves that need to be burned.

If you have noticed incurable diseases on hydrangeas, it is better to leave the flower forever, otherwise in the future the same problems will occur on other “favorites”. Diseases of hydrangea and their treatment will not disturb you if you regularly and correctly feed the flower, as well as find the right place on the windowsill and flower bed.
