Healthy hydrangea in the garden

The most common is hydrangea chlorosis. The disease is easily eliminated and is considered too dangerous for the flower. But, if you do not take action, then the specimen will become inconspicuous, lost among the rest of the greenery of the garden and stop flowering.

By what signs to determine the presence of chlorosis in a plant, even inexperienced growers can understand:

• The leaf plate begins to brighten and approaches yellow in color.
• The veins remain the same color - bright green.
• The inflorescences begin to dry out and eventually die off completely.

Manifestation of hydrangea chlorosis

Additional Information! Over time, the affected leaves may dry out and curl.

At the first signs of the disease, it is worth immediately taking measures to eliminate the problem. But first you need to determine the causes of the onset of the disease.

Causes of leaf blanching and the occurrence of chlorosis

Hydrangea is very fond of rich and fertile soil, which will provide an opportunity to develop strong stems and nourish huge inflorescences. If some element is missing, then metamorphoses begin to occur with the leaves of the flower.

Note! A metabolic disorder in the stem and root system also leads to a deterioration in the condition of the aerial part of the specimens.

Leaf discoloration

But most often the leaves turn pale, and then chlorosis appears if there is not enough iron in the soil. It turns out that iron for hydrangeas is the main nutrient responsible for the pigmentation of leaves and buds, as well as metabolic control.

Additionally, the acidity of the soil (pH) should be in the range from 4.0 to 6.5 units. If the acid level drops, then the shoots become pale. The flowers turn completely white. If you combine these 2 problems, then chlorosis is definitely provided.

How to treat hydrangea leaf chlorosis

If chlorosis of hydrangea leaves has begun, treatment should be effective and gradual. Much depends on the method and the chosen means. Folk methods and "drugs" do not always win in the fight against the disease. But special drugs can definitely help and will do it quickly.

Unconventional method - rusty nails for chlorosis

Some gardeners like to use unconventional methods to treat many of their favorites. There is also an unusual treatment option for hydrangea chlorosis, which involves the use of rusty nails.

Preparing a hole around the bush

How to cure a disease using rusty nails:

1. Make a groove around the bush at a distance of 5-8 cm. The depth of the hole should be between 5 and 10 cm.
2. Pre-select a lot of rusty nails of any size, size and degree of corrosion.
3. Place metal elements in the groove and dig in with earth.

Another recipe involves soaking rusty nails in a bucket of water for several days. This water is then used to water the bushes. It is not recommended to use a special infusion more than 1 time a week.

When watering, the rust will become limp and fall into the soil, enriching it with iron. But this option is ineffective, since rust releases little iron, and the plant will not be able to assimilate such a variant of the element.

Chlorosis treatment with iron preparations

To accurately cure the plant, you need to use special preparations that contain iron. There are many options for medicinal compositions that are suitable specifically for hydrangeas. Hydrangea chlorosis treatment involves the same as described in the instructions attached to the special preparation.

• Iron chelate (Mikom-reaction);
• Antichlorosis (Master Color);
• Brexil-Fe (Valagro);
• Micro-Fe (Orton).

Important! In some cases, the substance is diluted in water and the specimen is poured with such a solution. Sometimes, only the aerial part is sprayed. In especially neglected situations, it is necessary to use both watering and spraying.

To know exactly the condition of the soil, you need to carry out periodic tests that will show acidity. To do this, it is enough to purchase a kit with litmus paper and a special reagent.

Which plants are most susceptible to chlorosis

Even when buying a sprout or seedling, you should pay special attention to the state of the foliage of the specimen. You need to choose strong and large bushes for planting in the garden. But even this cannot guarantee 100% protection against disease.

A healthy specimen fell ill with chlorosis

Certain varieties themselves attract this problem. Large-leaved hydrangeas often suffer from chlorosis. A huge area of ​​leaf plates and inflorescences requires a special regime of fertilizers and dressing. The paniculate variety also often loses its green color. The aboveground part becomes pale and unremarkable.
