Florists know that the color of hydrangea depends on the composition of the soil. Using some available preparations, you can change its shade from blue to pink.
Just before you start watering the bush, you need to check the acidity of the soil in which the plant is planted.
We will tell you how to change the color of hydrangea correctly.
Soil acidity
You need to start with a small test. To find out whether the soil on your site is acidic or alkaline, you can use litmus paper, garden tools or table vinegar.
For an experiment in the kitchen, take a small amount of dry soil in a suitable container and pour vinegar over it.
The large bubbles that appear indicate alkaline soil.
A small number of small formations indicates a neutral soil composition, and the absence of reaction is a sign of acidic soil.
Blue Hydrangea
The hydrangea itself will tell you about acidic soil containing aluminum if its flowers are bright blue.
If adjustments are necessary, water the soil with a solution of citric acid (1 tablespoon of citric acid per 10 liters of water) with the addition of aluminum sulfate or colloidal sulfur.
Pink hydrangea
Bright pink hydrangea grows in neutral soil.
To change the color of the inflorescences, it will be enough to add dolomite flour or lime.
Phosphorus fertilizers can be used with the same success.
Warning
If you get carried away with coloring, you can ruin the plant. Few people know that exceeding the soil pH above 7 can cause the development of hydrangea chlorosis, and then there will be no time for flowering.
