Of course, if the leaves of a plant such as hydrangea begin to dry, then this will directly affect its appearance. Also, if the plant loses its strength, then it will be difficult for it to restore them. Therefore, it is best to carry out various preventive measures in order to avoid unpleasant situations, but if this has not been done, then it is necessary to start carrying out a complex of health measures as soon as possible.

Why hydrangea leaves turn red

If the plant is sick, then this can affect not only the foliage of the hydrangea, but also its inflorescences and root system. If you notice that the leaves of the plant have begun to turn black, turn yellow, or acquire a red or even brown color, then this may indicate improper care of the plant.

If only the edges of the leaves of the plant begin to dry, then this may indicate that you are watering the hydrangea a lot, or the soil is deficient in potassium. If the soil has insufficient acidity, then the plant begins to poorly assimilate various necessary elements for its development in the right amount. A lemon or oxalic solution can help in this situation. You need to take 1 tsp. substance and dilute it in 10 liters of water. Then, using the solution, water the plant.

If the plant experiences an excess of moisture or sunlight, or, conversely, their deficiency, then the foliage of the plants begins to acquire brown, black, red and yellow color. Therefore, before planting a plant in a permanent place, you need to think over the place in advance: the plant needs abundant, but not excessive moisture, bright, but diffused lighting. The best option would be to plant other trees and shrubs in partial shade. The appearance of rust can be associated with the scorching sun.

If the foliage began to turn yellow and fall off, then this may be the result of waterlogging. The plant becomes lethargic if the plant lacks light.

If the dried leaves have a rusty color, then this may be the reaction of the litmus test to an increased level of nitrogen in the earth. It is necessary to spray with a solution of 20 g of copper in 5 liters of water, or you can purchase special preparations at a flower shop.

The reasons for the reddening of the leaves can be any, even the wrong transplantation of the plant, while the root system of the plant was damaged. if you notice such signs, then you need to take measures as soon as possible to save the plant and return it to a healthy spring appearance so that it can grow and develop correctly. Also, the plant needs to provide the necessary watering and feed with the necessary preparations 3 times a month, for the formation of new roots.

Fertilizers can only be applied when the plant is fully restored. Indeed, for proper development, hydrangea needs a healthy root system.

If you notice that the leaves have become lethargic, then it is possible that the cause lies in the drafts. Therefore, it may be better to transplant the plant to a different location. you also need to avoid sudden temperature changes.

Also, the reason for the yellowing and reddening of the leaves can be a lack of nutrient intake, as well as an insufficient level of acidity.Therefore, to save the situation, you need to apply fertilizers 3 times a month. feeding with nutrients can be carried out from March to mid-July. Mineral fertilizers need to be introduced twice, and organic matter once.

Hydrangea leaves turn red, what to do. The appearance of chlorosis and how to deal with it

If the leaves of the hydrangea began to dry, then gardeners with experience know exactly what to do. The reason may lie in metabolic disorders, which can affect the change in the color of the leaves. The dry look of hydrangea is definitely not suitable. Dry leaves can be caused by chlorosis. It needs spraying and watering (if the case is running) with the following solution: 40 g of Agricola, Antichlorosis, Iron Chelate, Brexil Ferovit are diluted in 10 liters of water.

In order for the leaves of the plant to always have a healthy appearance, you need to ensure that:
• The soil under the plant was not oversaturated with substances such as lime and humus.
• Apply fertilizers containing iron.
• The plant must receive rainwater or water supply, but so that it can stand in the sun for at least 1 day.

The appearance of red leaves due to fungal diseases

Spots and the appearance of a whitish coating may indicate that the plant is suffering from a fungal disease. hydrangea has good immunity against fungal diseases, but such a situation is possible. Leaves can change their color, acquire brown-red and dark color. If at first the leaves turned black, and then a white bloom appeared, then this may indicate the appearance of white rot. The disease begins on the root system, it begins to rot, and this is reflected in the external state of the hydrangea.

The use of fungicides will help correct the situation. If spotting appeared on the leaves, then holes formed due to the death and drying of the watery tissue of the plant - this may also indicate the presence of a fungal disease - gray rot. Over time, gray bloom begins to spread throughout the plant. Also, the spread of spores will be dangerous for neighboring plants.

To avoid such a situation, you need to monitor the condition of the plant. if you notice that the leaves begin to curl, the edge begins to dry, then you need to start taking measures as soon as possible so as not to start the situation and the plant could be saved. Hydrangea leaves can begin to dry if the plant has undergone the following diseases:
• Phyllosticous and ascochitous spotting.
• Withering is tracheomycotic.

The use of fungicides can help save the situation. Drying of leaves can also appear due to other reasons. The appearance of brown and reddish spots may indicate the presence of septoria. A feature of the disease is that round spots at the edges have a darker color than in the center. The spot can be not only on leaves, stems and cuttings. If a number of necessary measures are not taken in time, then the foliage will begin to dry and die off, so the survival of the plant is impossible. Most often appears in the autumn. medicinal preparations are used for treatment. If the leaves began to curl and wither, then this indicates that the damage to the plant was caused by caterpillars, leaf beetles, bronze and earwigs.

Special attention should be paid to root knot nematode. Most often, young flowers are affected, as well as those shoots that have not been properly cared for. if the hydrangea is deficient in mineral elements, then the ends of the leaves will begin to dry out, as well as the appearance of a putrefactive process on the surface of the roots, which began due to the presence of swellings (gall). One process follows from another. If you do not fight the microscopic worm in time, then the leaves begin not only to fall off, but the entire plant may die.

Diseases of a viral nature

If you notice the presence of brown spots with a red tint, then this may indicate the presence of a viral disease. most often you can meet with calcium spot. The consequences of the disease can be seen on the curled leaves. First, spots appear that begin to change the shape of the leaf plate, which begin to roll up into a tube. Sometimes inflorescences may be damaged. This can mean the scale of the disease. the inflorescence begins to weaken, becomes small, or bud ovary does not appear at all. If you notice these signs, you don't have to wait for the plant to wither completely and infect nearby plants. unfortunately, there is no cure for calcium spot. And you need to save other plants so as not to lose them.
