Changing the Hydrangea color!
Did you know you can affect the color of Hydrangea by changing the acidity of the soil? Well, not the white variety, but the others will change colors. The more acidic the soil, the bluer the flowers will change, and if alkaline then it will turn the blooms into pink.
Basically you can manage to have a range of Hydrangea colors by just changing the nature of the soil. Many people use Miracid which is a fertilizer made by Miracle-Gro which increase the acidity of the soil. That will turn the Hydrangeas blue.
Some people add iron nails around the plant. You can add aluminum sulfate around the plant in early spring and repeat it later in the season. Everyone has their method of manipulating the Hydrangea color.
As you can see, you can simply change the look of your Hydrangeas without having to plant new ones but by adding an additive to the soil.
Hydrangeas have become very popular both in the garden, as potted plants, as well as cut flowers. Many times, you see cut Hydrangeas for sale, even in the supermarkets. They have large globes of the flower and just a few branches make a wonderful display of color in any room.
