From the list of diseases of this plant, those that cause the formation of spores of the fungus and viral microbes are noted. Another plant suffers from damaged metabolic processes. A summer resident who cultivates this herbaceous in his summer cottage must be able to recognize in appearance which disease is attacking the herbaceous one.

5. - snow-white rot.
6. - iron chlorosis.

Annular spot bacteria

This is a serious disease for this representative of flower crops. Ring spot bacteria are classified as a group of viral diseases. They are formed from the first spring month. The main indicator of the presence of this disease is curly dark brownish or black and red spots at the same time, growing on the affected leaves. To begin with, the spots are small in size and are often compared to dots, but they grow rather rapidly and change shape to a round shape with a depressed center. The foliage curls up, the dwarf shrub looks unnaturally branched.

Supplementary information. The specificity of the disease is that the affected inflorescences in the first twelve months do not show their presence on the plant in any way. All signs appear at the twenty-fourth month after infection, when the virus got inside the plant and disrupted all processes. Foliage, branches dry up in large numbers, herbaceous dies.

The annular herbaceous spotting bacteria usually gets through the affected soil or garden tools.

It is impossible to fight red rashes and drying out of the shrub from this disease, or rather does not make sense. And changing the place of growth will be useless. Summer residents with experience recommend getting grassy from the ground with a root system and burning it. The land in which the plant grew is disinfected.

Septoria, or white spotting

The disease is classified as a fungal disease. On the surface, the disease slightly resembles the above. There are specks of dark color on the foliage. Their color palette can be:

- brownish.

- reddish.

- brick.

Unlike the above disease, fungal spots are not circular. They spread in a random order, and the darkened areas clog the entire leaf plate.

Be careful! In addition to black spots, the leaves lose their green color, becoming yellowish. Herbaceous leaves off infected leaves. This disease can move to shoots and trunks.The best weather for the development of this hydrangea disease is rainy days and too hot.

This disease does not tolerate a fight only in the complex. To begin with, remove and burn all infected areas of the herbaceous. Then the ground under the shrub is disinfected. For this it is possible to use:

- Copper sulfate.

- Liquid bordeaux.

- Fittosporin.

- Baikal.

- Chlorine lime (exclusively in the autumn season).

Attention. It is also important to reduce the amount of soil moisture.

In order to cure this disease and the like, the following means are used:

- Kapptan.

- Proffit.

- Hom.

- Abigga Peak.

- Oxykhom.

- Phtallan.

Attention. According to summer residents, in critical cases, it is recommended to give preference to phthallan and oxykhom. Phtallan is not washed out by rainwater and rapidly attacks the fungus. The second drug is wonderful in that its component is copper, which quickly relieves the plant of this ailment.

Rusty coating, or rust

Disease of the fungus, which appeared due to the frequent change of the place of growth of the plant, especially when the shrub lacks space. An excessive amount of nitrogen contained in the soil also causes the disease. Rusty bloom is the answer to your misunderstanding, why does the foliage acquire a red color? A symptom of this hydrangea disease is a reddish bloom on the leaf plates. For a start, rusty areas can have a pinkish color, which darkens after some time.

Questions are quite common: why does the foliage of this plant acquire a reddish color? What to do about it? An effective way to get rid of this ailment at the first stage is to use the nutrient ferovit. It will help the herb to cope with the excessive amount of nitrogen and normalizes metabolic processes. Spraying with a stimulant will not be effective in the latter stages. Here summer residents with experience recommend using drugs:

- Raek.

- Skoor.

- Falcon.

- Topaz.

Rot is grayish and rot is snow-white

Two hydrangea diseases have fungal symptoms. Grayish rot absorbs branches and stems. They become too soft, they are often compared to jelly. Foliage, inflorescences are under a layer of plaque, which looks like ash. If especially hot days come, then faint spots are visible on the stems, leaf plates and petals, which acquire a pinkish color, then change to red and brownish colors at the same time, they can become completely red and fall off.

Snow-white rot infects the root system. Food from the ground will not be able to flow into the grassy one. As a result, the shrub is under a layer of snow-white bloom and rot.

At the first stages of the development of these diseases, the following means have an effect:

- Fundaazol.

- Toppsin M.

- Pure flowers.

- Bailleton.

Immediately before spraying the grass, all infected areas are removed.

Note. Before spraying the grass, all infested areas are removed. For a more effective effect, it is advised to carry out spraying procedures. The procedures are performed three to four times every week - one and a half.

A drug from the people for a fungus that causes rot is a liquid with horsetail. Horsetail is allowed to be used dry and fresh. Five liters of liquid requires five hundred grams of fresh grass (or one hundred grams of dry grass). Then the mixture is left untouched for a day and sorted. The drug is diluted with twenty liters of water, which has been defended in advance. The product is used for spraying and moisturizing.

Iron chlorosis

This disease is one of the most frivolous. The disease is not classified as fungal and viral. It can infect both this plant and other types of shrubs.

This disease appears due to damage to metabolic processes in the herbaceous.In this case, chlorophyll, which must form in the leaves, stops producing it. As a result, the foliage loses its natural color. They become paler, and then salad and yellowish at the same time. And the veins do not change color and so remain saturated with green color. Summer residents with experience know that damage to metabolic processes is due to a lack of iron in the ground. The herbaceous one lacks a component, and it begins to die.

Note. Another option for infection is considered to be too much manure in the soil. Top dressing contributes to the destruction of the work of the systems responsible for the decomposition of iron.

Regardless of the rather harmless nature, it is forbidden to be inactive. The development of this disease leads to the depletion of the shrub, the absence of flowering buds, and the loss of its decorative appearance. Due to this disease, hydrangeas can become infected with more serious diseases.

Ways to get rid of various diseases of this representative of flower cultures

The procedure is carried out as spraying the shrub or moistening a part at the roots.

For those who do not want to buy a ready-made drug, summer residents with experience recommend making the nutritional preparation with their own hands. A container of soft hot liquid is useful for this. Three grams of edible lemon acid and one or two grams of iron sulfate, or ferrous sulfate, are poured into it. All mix well. The preparation is suitable for spraying shrubs. But the self-made preparation of the drug is used in the early stages of this hydrangea disease. For more effective treatment, it is recommended to use industrial drugs.

It is important for a summer resident to be able to identify diseases that infect a given plant. Diseases of this herb hydrangea and their treatment involves the use of fungicidal preparations.
