Hydrangeas: flowers in many different colors
Hydrangeas not only bloom conspicuously pretty, the big flower umbels can also change the tint like a chameleon. This makes the care of these beauties so attractive, because they are unlike other perennials not set to a flower color. What standard tones the flowers have and how they can change, you will learn in this article.
White hydrangeas
White hydrangeas look particularly noble and elegant and set beautiful accents in the shady areas of the garden through their bright umbels.
Unlike other varieties, the plant substrate white hydrangeas need not have a specific pH. A nutrient-rich, moist, slightly acidic and loose surface meets all the requirements of the plant.
The pink-colored hydrangea
This is the original flower color of the pretty perennials. For the flowers to appear permanently pale pink, the pH value of the soil must be around 6. If the soil is too acidic, regular prizes help. In addition, you can occasionally fertilize the pink-colored hydrangea with a high-phosphorus fertilizer, which inhibits aluminum uptake.
Flower miracle in blue
Many pink flowering hydrangeas are able to change their flower color and produce blue flowers. For this purpose, the soil must have a pH between 5.2 and 5.5, so that the plant can absorb the aluminum present in the soil and responsible for the flower coloration.
Therefore, plant blue-flowering hydrangeas in special hydrangea or rhododendron soil. Alternatively, you can subdue peat, foliage compost or organic plant material to the topsoil. Fertilize the blue hydrangea exclusively with low-phosphorus special fertilizer, which should also have a high potassium content.
Red and redpink colored hydrangeas
Red hydrangeas, on the other hand, require alkaline soils to retain their rich tints. If the surface is too acidic, the color fades relatively quickly. Here too, you can shift the pH value to the optimum range by regularly adding limescale. He should settle at around 6.5.
Tips & Tricks
A common phenomenon that makes hydrangea so special is its bicoloured and finely shaded flowers. Also two different flower colors on a plant occur.
