      - This is a sign of powdery mildew. As the fungus develops, the mycelium becomes denser and the plaque becomes brown. Affected plants can be severely weakened. More resistant to this disease G. oak-leaved less - large-leaved Hydrangea.
      Will help to cope with powdery mildew multiple treatment with drugs (at choice): "Rakurs", "Topaz", "Chistotsvet", "Agrolekar", "Polar-50", "Baxis" (at least 4 repetitions per season, once every 7 days) ...

      Powdery fungi prefer to infect slightly withered leaves, the cells of which have lost their turgor. Therefore, regular watering during dry periods increases the resistance of this moisture-loving crop to disease.

      Symptoms of some diseases appear quite late, sometimes only in the middle of summer. Therefore, fungicide treatment does not always give quick results. Next year, start preventive treatments in late May and early June — before the first signs of the disease appear.
      Prevention
      For the normal development of hydrangeas, regular feeding is necessary throughout the season.
      Pruning plants periodically to ensure free air circulation and dryness after rains.
      Timely removal of affected leaves / inflorescences from the bush, collection of all fallen and their destruction.
      Thorough loosening of the soil in the fall (can be combined with the introduction of phosphorus-potassium fertilizers of prolonged action).

    At one time, I planted the usual white hydrangea on a site with very sparse soil. And she surprises every summer with lush flowering.
    And Vanilla Freyz placed the hydrangea she bought on a site with better soil, and she disappointed - the leaves turn yellow, then she looks like she is sick.
    The reason?

      Hydrangea is very demanding on the composition of the soil. If it does not fit, the flowers become smaller, the leaves brighten, and the plant looks like it is sick. And the reason is the lack of nutrients.
      The first thing to do is to check the acidity of the substrate. To hydrangea felt at ease, acidity in the range of 4,0-6,5 is needed. And if the plant has yellowed leaves, feed it with a special fertilizer for hydrangeas. Moreover, dressing can be carried out on the leaves. You need to do this twice a season.
      Powdery mildew, which spreads on young shoots, also sometimes attacks this plant. Special drugs, fungicides, including the biological Fitosporin-M, help fight off the attack. And parts affected by the disease should be removed and burned.

      Often on hydrangea you can see insects that feed on its juice. A drug such as Fitoverm copes well with them.
