Hydrangeas are one of the most popular garden plants.
Blue flowers in particular provide colorful eye-catchers.
With a trick, they don't fade so quickly.
Munich – White, pale pink, violet or even blue: hydrangeas are very popular ornamental shrubs in this country due to their variety of colours.
They ensure a colorful sea of flowers in the native green and make the garden ambience look friendlier.
Blue hydrangeas are particularly popular.
But it is not easy for the plants to keep their rare and beautiful colour.
Sometimes the color fades quickly and/or the flowers suddenly turn pink.

So, before properly caring for hydrangeas to keep them blue, it's important to understand how the color comes about.
Because some pink hydrangea varieties turn blue if they are in acidic substrate.
So if you want to make the effort, you need acidic rhododendron soil.
This can be a problem if your regular garden soil tends to be neutral and calcareous.
In the green at home, gardeners therefore have to work a little harder and enrich the hydrangeas with hydrangea blue (aluminium sulphate) until the first blossoms appear.
However, that can cost a lot of money.
In addition, the plant does not remain as beautifully blue as desired in the long run, despite the chemical blue-maker.
Many people don't have one reason for this on their radar: watering with tap water.
Vinegar can help here.

Finally, tap water neutralizes the artificially acidified soil.
With the result that the hydrangeas only bloom in a pale to lilac-blue.
However, if you want an intense blue, you have to keep the soil permanently acidic.
Vinegar is cheaper.
But that's trickier than you think: because gardening enthusiasts should pay attention to the right dosage.
Therefore, proceed as follows:
When the hydrangeas show color in the buds, use a pitcher of rainwater.
They have previously added a dash of vinegar to this.
Make sure you never put vinegar straight on the plants!
The hydrangeas do not survive the home remedy in its pure form, which is usually used to combat weeds.
Water the hydrangeas evenly with the heavily diluted vinegar water.
Now it's time to wait and watch the color of the flowers.
This simple life hack will permanently turn the hydrangeas blue without having to swing the chemical club.
But only if you water the hydrangeas regularly.
After all, the shrubs need a lot of water.
