To change the color of your pink-flowering hydrangeas, you can alter the soil pH with vinegar. Simply dilute vinegar in water and pour it around the base of your hydrangeas, and within just a few weeks, you could have fresh and bountiful blue blooms. To make the soil more acidic, add aluminum sulfate or wettable sulfur to the soil.
To turn new hydrangeas blue, use 1¼ cups of Espoma Organic Soil Acidifier. For established hydrangeas, apply 2½ cups of Organic Soil Acidifier and spread evenly around. To turn new hydrangeas blue, mix ¼ oz aluminum sulfate with a gallon of water and soak the soil surrounding your hydrangeas in the spring, as soon as the plant begins to grow.
Alternative methods for turning hydrangeas blue include using coffee grounds, which can increase soil acidity and result in bluer flowers. Lime can also be used to turn hydrangea flowers pink by applying garden/agricultural lime according to the recommended dose.
In summary, changing the color of your hydrangeas is a simple and effective way to enhance their beauty. By adjusting the soil’s pH levels, you can achieve a more vibrant and colorful bloom. Coffee grounds, vinegar, and eggshells are all effective ways to achieve this effect. By following these tips, you can ensure that your hydrangeas will grow into beautiful, vibrant blooms.

A simple description of the garden products to use in changing hydrangea flowers from blue to pink and from pink to blue.
Can you turn a pink hydrangea blue?
To turn hydrangeas blue, use 1 tablespoon of sulfur or an organic soil acidifier per 4 inches of pot diameter and water it in. Repeat at 60-day intervals until desired color is achieved. A pH of 5. 5 results in violet-blue blooms, while a pH of 4. 5 produces a deep blue. A pH of 5. 0 produces a muted blue.
When planting hydrangeas in the ground, mix soil acidifier into the soil and repeat at 60 days if desired. Reapply each spring and again if needed. Espoma Organic Soil Acidifier is a safer option, containing 30 sulfur and recommended for 1 1/4 cups around each new plant or 2 1/2 cups around established plants.
Coffee grounds can also be used to turn hydrangeas blue, but research shows the effect is short-lived. Use a 1/2 inch depth of grounds and mix them into the soil, as they can harden on the soil surface and repel water. Pre-brewed coffee grounds are neutral and less likely to impact the color.
How do you make a hydrangea blue?
To turn hydrangeas blue, adjust the soil’s pH by adding aluminum sulfate, coffee grounds, vinegar, or other substances. This is a proven method for changing flower color, but it may take up to a year for the flowers to transition to the desired shade. The process is gradual and may require multiple applications. Re-test the soil’s pH and adjust treatments as needed. If the hydrangeas already bloomed pink, they may not see blue flowers until next year.
Soil amendments affect developing buds, not bloomed flowers. Be cautious when lowering the pH too much or too quickly, as this may cause plants to struggle to absorb necessary nutrients. If the pH becomes too low, apply lime to raise it back up.
Does vinegar turn pink hydrangeas blue?
The addition of vinegar to watering cans can facilitate the creation of blue hydrangeas by altering the soil acidity. Nevertheless, this approach is not advised due to the potential adverse impact on wildlife and its suitability as a long-term solution for blue hydrangeas.
Will baking soda make hydrangeas blue?
Loamy soil has high soil buffering capacity, making it resistant to pH change. Baking soda, a small amount, doesn’t significantly impact the hydrangea’s color, as it leaves the pH unchanged. Adding more can damage roots and potentially kill the plant. For practical pH alterations, use soil amendments like sulfur to lower pH and lime to increase it, as these amendments have been proven to be effective.
How to keep a pink hydrangea pink?
The optimal pH range for pink hydrangeas is approximately six, which is less acidic and more alkaline. To reduce the acidity of the soil, it is recommended to spread wood ashes or limestone over the surface and incorporate them into the soil using a hoe or tiller. Oakleaf and panicle hydrangeas, which produce white flowers that gradually transition to pink and red hues as the season progresses, are particularly well-suited for cultivation.
Do coffee grounds turn pink hydrangeas blue?
Hydrangeas’ color is influenced by the acidity of their soil. The more acidic the soil, the more blue the blooms. To achieve the best blue hydrangea blooms, add coffee grounds to the soil. The pH level of the soil is crucial for hydrangeas to bloom. Higher acidity results in bluer blooms, while more alkaline soil produces pinkish flowers. Some hydrangea names, like Nikko Blue and Nantucket Blue, are influenced by their soil’s pH level. French hydrangeas are known for their globe-like blooms, which can be manipulated to suit color preferences.
To ensure blue blooms, ensure the soil is acidic. Fertilizers can help, but leftover coffee grounds can be just as effective and cost-effective. French hydrangeas are prized for their globe-like blooms, which can be manipulated to suit individual preferences.
Does lemon turn hydrangeas blue?
To alter the color of pink flowers from pink to blue, it is sufficient to squeeze the juice of lemons or limes over the plant, thereby increasing the acidity level of the soil, and then allowing the flowers to revert from pink to blue.

Does coffee turn hydrangeas blue?
Coffee grounds can be used to change the color of hydrangeas, but it’s best to use aluminum sulfate for a proven flower color change. Crushed eggshells may work, but they should be used with a proven method of raising the pH, like applying garden lime. Vinegar can be added to watering cans to change soil acidity and turn hydrangeas blue, but it’s not a long-term solution and can be harmful to local wildlife.
