Would you like to see how your hydrangeas look different? You can change their color on your own. This is what to know.
Not all hydrangeas are able to change color. There are some Bigleaf hydrangeas that have this ability. Those with white flowers can't change their color.
If you want to change the color of a plant's flowers, be sure to wait at least two years. It is important to remember that it takes several weeks or months for the change to occur.
The color of the plant depends on the amount of aluminum it can absorb from the soil.
It's easier for plants to absorb aluminum with a lower pH. The higher the soil's pH, the harder it is for the plant to get access to aluminum.
The first thing you need to do is test your soil. It's important to have some aluminum sulfate. The next thing to do is here.
The acidity of the soil should be increased to make pink and blue flowers. In the spring, you can apply a solution of 14-ounce aluminum sulfate per gallon of water.
You should repeat the process three or four weeks after that. If you use the aluminum sulfate solution in the spring, you need to apply 25-5-30fertilizer.
Increasing the alkalinity of your soil will allow you to go from blue to pink flowers. It's possible to spread ground limestone at a ratio of four pounds per 100 square feet in the spring or fall to make sure it gets plenty of water. The manufacturer has instructions for putting 25-10-10 on the plant.
Water with a high mineral content can help turn blue flowers pink.
