The art of colors in your garden

hydrangeas are not only decorative, but also remarkably changeable. Their ability to change the flower color according to the ground values ​​is a fascinating challenge for many garden owners. Choosing the right location and suitable care play a decisive role in enjoying the magnificent flowers in full splendor.

The right floor composition

In order to cultivate a blue hydrangea, the soil must correspond to acidic conditions. According to the information from the Lower Saxony Chamber of Agriculture, the key to the blue color is under a pH of less than 4.5. In this milieu, the roots can absorb the necessary aluminum or iron that is responsible for the blue color. However, if the pH value is over 6.0, the color of the flowers is often disappointing pink.

creative tips for changing the color

In the television program "We in Bavaria", garden expert Andreas Modery revealed a rather unusual but practical tip to get the desired color of the hydrangeas. Instead of using expensive special fertilizers, hobby gardeners can use an old sock. This is filled with rhododendron earth and hung in a water filled with water overnight. This procedure makes the irrigation water slightly acidic and promotes the blue coloring of the hydrangeas.

additional measures for care

In addition to the sock method, there are numerous other means to influence the flower color in the long term. Leaves, needle leaves or even coffee grounds can be incorporated into the ground to increase the acidity. Alternatively, there are also special garden products such as alum or calial sauna that are available in the pharmacy and can regularly be administered with the irrigation water. These prevent a pink to overturn blue and provide healthy, strong flowers.

Why the variety of colors is important

The different colors of hydrangeas are not only an aesthetic pleasure, but also reflect the care and the conditions that prevail in the garden. Gardening awareness that is awakened by experimenting with colors can encourage gardeners to deal with nature more intensively and to develop a better understanding of the flora. Gardening not only contributes to the beautification of the environment and living space, but also trains the ecological awareness of the community.
