HOW TO "REPAINT" HYDRANIA IN BLUE
Large-leaved hydrangeas are considered to be the decoration of any garden. Alexandra OSADCHAYA from shares her experiment on repainting pink inflorescences in blue. Moreover, the bushes planted in different parts of the garden turned out to be of different colors - from light blue to intense blue.
HYDROENSIA INDIGO
At the end of September, I dug up two-year-old bushes, transplanted them into containers, watered them and sent them to a dry basement (I watered only once during the winter). At the same time, red high-moor peat was introduced into the planting pits (20-25 cm deep) to acidify the soil.
The following spring, I planted hydrangeas in them, mulching the soil around the seedlings with a mixture of high-moor peat and coniferous bark. As soon as the buds began to appear, I began to water the plants with aluminum alum (5-7 g / l of water).
I filtered the water, because hydrangeas do not react well to chlorine and lime. I watered (2-3 liters per plant) once every one to two weeks during the entire growing season, taking into account weather conditions and preventing the soil from drying out. Once every 2 months, starting in May, I fed the hydrangea with potassium sulfate and superphosphate (1 tablespoon / 10 liters of water each).
RESULTS OF PAINTING HYDROANGIA
In the first year, the color of the bushes was "transitional": along with the azure inflorescences, pink ones continued to flicker. But already in the next season, subject to the same measures, the blue color became persistent.
I consider the reason for the uneven coloring to be the lack of aluminum sulfate, therefore, to maintain a blue tint, I water the hydrangeas alternately with a solution of aluminum alum and water infused with high-moor peat for 1-2 days.
In addition, I buried a few rusty nails in the trunk circle. As a result, the inflorescences of hydrangeas became indigo and surprised with their bright color until the very cold.

Today, hydrangea is in fashion: two-meter bushes with multi-colored balls of flowers on tall stems look gorgeous along garden paths, near the porch and in the middle of the green expanse of the lawn.
And do not be upset if you bought a blue hydrangea for planting, and you have a pink one.
It's all about the soil! It is enough to work a little on its composition, and the color of the flowers will easily change.
Water, for example, before flowering plants with aluminum alum (5 g per 1 liter of water), and the white color will change to blue, and pink to lilac. When iron salts are added, hydrangeas turn bright blue, almost blue (I mix a little iron filings into the soil or, even easier, stick a few nails into the ground).

I love hydrangea because it changes color like magic. In some gardens it is pink, in others it is snow-white, in others it is cream, in the fourth it is blue ... I dream of conducting an experiment in my dacha: in one garden I want to grow hydrangeas of different colors. In principle, this is possible, because the color of the hydrangea depends on the composition of the soil on which it grows (acidity, the content of iron and aluminum salts in it). Has anyone, I wonder, conducted such experiments in their country house?

Dear Lydia Ivanovna, paniculate hydrangea flowers change their color gradually: white when dissolved, they then become pale pink, then change color to bright pink, then to raspberry with a slightly purple tint, and, finally, by autumn they become red-beige.
Large-leaved hydrangea is the most colorful and magnificent, but also the most delicate. In Central Russia, it does not hibernate in open ground, it is often used as a houseplant.
