The Magic Trick To CHOOSE the Color of Your Hydrangeas.
Hydrangeas are beautiful flowers in the shape of large pom poms.
These flowers have amazing colors: they can be pink, blue, white, or even green.
In addition to this, there is a magical side: the hydrangea adapts its color to soil pH function.
Below a pH of 5.5, the flowers are deep blue. Between 5.5 and 6.5, they have a beautiful lavender color. And at over 6.5, they turn pink or red.
You can therefore choose the color of your hydrangeas easily by changing the pH of the soil.
The trick is using white vinegar and baking soda to change soil pH. Look :
1. For pink or red hydrangeas
In order for the flowers to turn pink, they need alkaline soil, that is, with a pH over 6.5.
To do this, put 2 teaspoons of baking soda in your watering can. Water the hydrangea with this mixture about once a month.
Over time, the soil will become more alkaline. The flower will then take on pink and red reflections.
2. For blue hydrangeas
In order for the flowers to turn blue, you need a more acidic soil with a pH between 4.5 and 5.
To do this, dilute 2 cups of white vinegar (about 500 ml) in 4 liters of water. Then, water the hydrangeas with this mixture. Adapt the amounts of vinegar according to the size and age of the plant. If it is in a jar, use less vinegar.
Then, have the slate plundered at the foot of the hydrangea and leave to act.
You can also replace the slate with rusty nails. Plant them in the ground in the direction of the roots.
There is also commercially available alumina sulfate powder to be diluted in water to obtain the same effect. The only difference is the higher price.
Additional advice
Be aware that a white hydrangea will never turn fuchsia pink.
It is often the edges of the flower that will take on a pink color.
Also depending on the hydrangea species, you won't necessarily get a deep blue, but maybe just a bluish sheen.
In any case, if you want abundant flowering, keep a soil with a pH below 6. But be careful, this must be done well BEFORE flowering!
