Pink hydrangeas - the transformation artists in the flowerbed
If you love a romantic bed design, in which the flowers of the plants bribe in a year by harmonious colors and next year set colorful color contrasts, you are in the right place with hydrangeas. The relatively easy-to-maintain Hydrangea usually blooms pink, but depending on the soil can change the color of the flowers to purple, blue or red. In order to preserve the pure flower color, some care measures may be necessary.
Pink is too blue
It is not unusual and makes the special charm of this plant that many hydrangeas wear different-colored umbels and that the individual flowers are sometimes even multicolored.
Responsible for the different colors is the pH of the soil and the aluminum content of the soil. Only if this value is about 6, the hydrangea decorates with pink flower umbels. If the value is lower than this one speaks of an acid soil and the hydrangea changes its flower color to blue. On alkaline soils with a pH above 7, the tint often changes to a rich red.
The original color received
To ensure that the hydrangea does not undesirably change color and retain its delicate flower color, you must ensure that the soil value has a pH of about 6. If you have acidic or alkaline soil in your garden you can analyze it with test sticks.
If you need to raise the pH slightly, you can acidify too acidic soils by regularly adding lime.
On the other hand, if your garden soil has an alkaline pH above 6.5, you can artificially move it to the acidic area so that the hydrangea will continue to have pink flowers.
Organic materials such as
In contrast, peat should only be used in exceptional cases out of consideration for nature.
Heavy loamy soils can be acidified very well with sulfur or Einsensulfat. All means of artificial soil improvement must be well incorporated into the soil.
Tips & Tricks
You only have real control over the flower color if you cultivate the hydrangea in the pot. You can also put the pretty shrub with the plant container in the flower bed, so that the garden soil has no influence on the color of the flowers.
