While pink hydrangeas bring a delightful touch of beauty and vibrancy to gardens, blue hydrangeas possess a unique charm that many consider to be superior.
When you first transplant hydrangeas, they often undergo a subtle shift in color as they adapt to their new soil. Varieties like hydrangea macrophylla and serrata can showcase various colors, from pinks to blues, including various fuchsia, plum, and violet shades.
The rarity of blue among flowering plants makes it particularly appealing for gardeners looking to create an eye-catching outdoor space. Interestingly, you might already have the potential for stunning blue blooms lurking in your garden, waiting for the right conditions to emerge.
If you’re longing for a sea of blue but already have hydrangeas planted, there’s a home remedy that one gardener has successfully used to change their color without additional purchases.
Sarah Hick shared her experience on the Hydrangeas in the UK Facebook page, explaining how she transformed her store-bought pink hydrangeas into vibrant blue ones simply by adding coins to the soil.
She expressed her delight with her new blue blooms and noted that while she also enjoys the pink variety for its lovely contribution to her garden’s palette, many believe that aluminum sulfate is essential for achieving blue hues in hydrangeas—a substance readily available at most garden centers.
Alternatively, organic options like coffee grounds, eggshells, or citrus peels can naturally acidify the soil; just grind these materials and mix them into your garden bed.
Remember that these adjustments will take time—consistent application over an entire year may be necessary before reaching optimal acidity levels for color change.
