Treating hydrangea from Oidium
Oidium is onediseasewhich affects many plants, including thehydrangeas. It shows white patches on the leaves and branches, in the advanced stage, the powdery mildew leads to the withering and fall of leaves and branches.
The ideal conditions ofpowdery mildewthey provide a shady area with temperatures between 15 and 26 ° C and do not need humidity to thrive. To eliminate powdery mildew from hydrangeas you can alter the pH: just prepare a solution to spray on the leaves and plant by mixing 2 or 3 drops of dish soap (free of perfumes or bleach), 1/2 tablespoon of baking soda to half a liter of water.

Prevention: here's why fertilizing hydrangeas
Good garden maintenance will protect your plants from the onset ofillnesses.
Water thehydrangeain the early morning avoiding wetting foliage or flowers, irrigate directly at the base of the plant.
Remember to do a good pruning of the hydrangea so as to allow air circulation between the branches. Poor air circulation increases the possibility of fungal and parasitic attacks.
Remember to fertilize yours on timehydrangea. The fertilizer provides the plant with all the nutrients necessary to activate a good response to various attacks. Just like us, through nutrition we should heal and strengthen our immune defenses, plants try to improve their defense mechanisms by exploiting the nutrients present in the soil.
All plants are sessile organisms, which means that, unlike animals, if they see a danger they cannot run away but are forced to face it. The defense and adaptation mechanisms of plants should not be underestimated.
To guarantee yourshydrangeasalways a good availability of nutrients, it is necessary to fertilize the soil.
Be careful to choose a complete fertilizer. Unfortunately, most of the acidophilic fertilizers for flowering plants that you find on the market, support the plant only from a flowering point of view. Fertilizers should support the entire growth of the plant and provide the nutrients necessary for flowering but also to support the green parts. Ideally, a fertilizer should be such as to improve not only the quantity of micronutrients in the soil but also the structural quality of the soil as well as the presence of microorganisms useful for the plant.
Among the various fertilizers on the market I would like to point out one of German import. It is a specific fertilizer for hydrangeas, completely natural.
The fertilizer in question can be bought on Amazon at a price of 11.15 euros with free shipping. For all information, I refer you to the product data sheet: Neudorff specific fertilizer. The fertilizer is natural and harmless to pets and insects.
Hydrangeas are resistant plants but also - from some points of view - very demanding, so regardless of the brand you choose, take a specific fertilizer.
