To turn hydrangeas blue quickly, you can adjust the soil’s pH level by adding aluminum sulfate or using a fertilizer specifically formulated for blue flowers.
By following these methods, you can change the color of your hydrangeas from pink or white to vibrant blue in a relatively short period.
Introduction To Hydrangea Color Change
Hydrangeas can change color based on the acidity of the soil they’re planted in. Highly acidic soil with a pH below 5.5 will produce blue flowers, while alkaline soil with a pH above 7 will result in pink or even red blooms. The key to turning hydrangeas blue quickly is to lower the soil pH by adding ammonium sulfate or aluminum sulfate.
These compounds can be applied directly to the soil to encourage the plants to take up aluminum, which in turn promotes the formation of blue pigments in the flowers. It’s important to test the soil before making any adjustments and to monitor the pH levels regularly to maintain the desired color of the hydrangeas.

Mulching For Color Maintenance
Using the right mulch can help maintain the blue color of your hydrangeas. Organic mulches such as pine needles, sawdust, and bark chips lower the soil pH level, making it more acidic. This acidity is necessary to keep the flowers blue. Inorganic mulches like stones and gravel do not affect the soil pH level and are not recommended for color maintenance.
Types Of Mulch To Use
| Type of Mulch | Effect on Soil pH |
|---|---|
| Pine needles | Lower pH |
| Sawdust | Lower pH |
| Bark chips | Lower pH |
| Stones | No effect on pH |
| Gravel | No effect on pH |
Proper Mulching Techniques
When mulching around hydrangeas, make sure to keep the mulch a few inches away from the base of the plant to prevent rot. Apply a layer of mulch 2-3 inches deep around the plant, making sure not to cover the stems. Reapply the mulch annually to maintain the color of the flowers.
Fertilizing For Optimal Results
Fertilizing is crucial for turning hydrangeas blue quickly. Choosing the right fertilizer is the first step towards optimal results. Look for a fertilizer with a high phosphorus content. Timing is also important; apply the fertilizer in early spring before the plant starts growing.
Hydrangeas also benefit from a second application in early summer. When applying the fertilizer, be sure to water the plant thoroughly afterward to help the nutrients penetrate the soil.
Additionally, consider adding aluminum sulfate to your soil to further enhance blue coloration. However, it’s important to note that too much aluminum sulfate can harm the plant, so be sure to follow instructions carefully. With the right fertilizer and application techniques, turning hydrangeas blue can be done quickly and easily.
