Hydrangeas are plants that have been impressive for years. Especially when they have a beautiful blue shade. To achieve this effect, we must take care of the ground in which our plant develops. Fortunately, all you have to do is use a simple home way to get the desired result. Check what to use.
The color of the garden hydrangea flowers depends on it What reaction has the soil, or what is its pH. The color of the flowers of the plant is determined by the presence of anthocyanins, i.e. natural plant dyes and their reactions with aluminum ions, which the plant absorbs only in the acidic environment.
Scientists indicate that Delphinidine pigment is responsible for the blue hydrangea and creates permanent complexes with aluminum in acidic pH, so To obtain such a shade of flowers, we must provide the plant with acidic substrate. However, if we are dealing with alkaline soil, i.e. one that has a pH above 6.5 The plants will bloom purple or pink.
Therefore, if you want to have blue hydrangeas, it is worth trying a natural way to acidify soil. Thanks to this, we’ll get a dream shade of flowers in a cheap and easy way. It turns out that coffee coffee grounds are enough for this. This is a natural method that will allow you to acidify the soil.
This is due to the fact that coffee contains organic acids and has a gradual lowering pH. It is a slower process than using chemicals, but cheap and ecological. If you want to use it, you just need 2 tablespoons of fresh coffee grounds around the bush once a week. Composted coffee coffee grounds can even lower the pH of the soil by 0.3-0.5 units during the season, if we use them regularly. In addition, they will greatly affect the soil structure and microbiome.

We should also remember not to plant this plant in a sunny position, because the strong sun will not serve our plant. She will feel much better in partial shade.
It is also worth taking care of Mulching the soil, because during the drought period, it will prevent moisture loss. Let’s not forget about systematic fertilization, which will affect the quality and quantity of flowers. However, be careful that Do not use too large amounts of preparations so as not to get the opposite effects and not harm the plant.
