How to change the color of hydrangea? This home trick is easier than you think

Flower color can only be changed in certain hydrangea species, mainly those related to H. macrophylla or H. serrata. It is commonly believed that the color of flowers is related to the pH of the soil. However, the color does not depend on pH per se, but on the amount of aluminum the plant has access to in the soil.

A lower pH allows aluminum to be dissolved and absorbed by plants (unless phosphorus levels are high), and the flowers tend to be blue in color. The higher pH blocks the aluminum and the flowers are usually pink. Shades of cream to green may also be visible when the flowers first open, and shades may change as the flowers age.

Okay, here’s the promised trick. To make the soil more acidic, sprinkle ½ cup of garden sulfur on the soil under the hydrangea and water it. To make it more alkaline, do the same with ground lime. You can also get such products in gardening stores. Depending on plant size and soil conditions, multiple applications may be necessary at 60-day intervals. Be patient; results may take months or not become visible until next year.

Can coffee grounds be used to change the color of hydrangeas?

Some gardeners have reported success in turning hydrangeas blue by applying coffee grounds to the soil. Coffee beans make the soil more acidic, thanks to which the hydrangea absorbs aluminum more easily. Additionally, fruit peels, lawn clippings, peat moss and pine needles are believed to have a similar effect.

Can eggshells be used to change the color of hydrangeas?

If you want pink hydrangeas, crushed eggshells may be one way to get them. Eggshells slowly decompose and reduce the acidity of the soil, making it difficult for hydrangeas to absorb aluminum. These are just some of the natural ways to make colorful flowers, many people also use vinegar or lemon juice.
