How to Change Hydrangea Color

why change color?

While the flower’s color is determined by the plant’s genes, there are ways to change the color of hydrangeas. The easiest way to change the color of a hydrangea is to adjust the pH level of the soil.

If you want your hydrangea to be pink, you would need to make the soil more acidic. This can be done by adding sulfur or aluminum sulfate to the soil. You can also add composted leaves or coffee grounds, as they will also lower the pH level of the soil.

If you want your hydrangea to be blue, you would need to make the soil more alkaline. This can be done by adding lime to the soil. You can also add wood ashes or crushed eggshells, as they will also raise the pH level of the soil.

Section 1: What You’ll Need

If you want to change the color of your hydrangea, you’ll need a few things. First, you’ll need some gloves to protect your hands from the stain. You’ll also need a paintbrush and some fabric dye. Make sure to get a dye that is specifically made for fabric; otherwise, it won’t work as well.

Once you have all of your supplies, mix the fabric dye according to the instructions on the package. Once it’s mixed, start painting it onto the flowers of your hydrangea. Work in small sections so that the dye doesn’t dry before you have a chance to spread it evenly.

After you’ve finished dying all of the flowers, wait for them to dry completely before moving on to the next step.

Section 2: When to Change Color

When it comes to deciding when to change the color of your hydrangea, there are a few things to keep in mind. First, you’ll need to consider the type of hydrangea you have. There are two main types of hydrangeas – bigleaf and oakleaf. Bigleaf hydrangeas can be changed from pink to blue or blue to pink, depending on the soil pH. Oakleaf hydrangeas, on the other hand, are not as responsive to soil pH and usually retain their original color.

Soil pH is an important factor in changing hydrangea color because it affects the availability of aluminum ions in the soil. Aluminum ions are what give hydrangeas their blue color.

Section 3: The Process of Changing Color

When it comes to changing the color of hydrangeas, there are a few different methods that can be used. The most common method is to alter the pH levels of the soil. This can be done by adding either lime or aluminum sulfate to the soil. The amount that is added will determine the final color of the flowers. For example, if you want pink flowers, you would add more aluminum sulfate to the soil. If you want blue flowers, you would add more lime to the soil.

Another method for changing hydrangea color is through plant food. There are special fertilizers that can be used that will change the color of the flowers. These fertilizers usually contain either phosphorus or potassium. The amount of fertilizer that is used will also determine the final color of the flowers.

Section 4: After Care

After the flowers have been removed and the stems have been cut back, it is important to give the plant some after care. This includes fertilizing the plant and making sure it gets enough water. It is also important to deadhead any spent blooms to encourage new growth.

Conclusion

If you want to change the color of your hydrangea, there are a few things you can do. You can alter the pH of the soil, use colorant sprays, or fertilize with aluminum sulfate.

Altering the pH of the soil is probably the most effective way to change hydrangea color, and it is also the most permanent. To make soil more acidic, add elemental sulfur or aluminum sulfate. To make soil more alkaline, add lime.

Colorant sprays are less effective than altering the pH of the soil, but they are much easier and faster. You can buy colorant sprays at most garden stores. Just be sure to follow the directions on the package.

Fertilizing with aluminum sulfate will also change the color of your hydrangeas.
