Do coffee grounds change the color of hydrangeas?
Some gardeners report success in turning their hydrangeas blue by applying coffee grounds to the soil.

Why did my hydrangea turn purple?
Hydrangea leaves that turn purple may be trying to tell you that there simply isn’t enough phosphorus nearby to keep the plant healthy. Check your soil pH — acidic soils with pH below 6.0 often allow aluminum to tie up phosphorus, those alkaline soils with pH above 7.0 may be binding it with calcium or magnesium.
How do I acidify my hydrangeas soil?
Soil can be made more acidic by adding Soil Acidifier, ammonium sulfate or aluminum sulfate. Follow application rates on the packaging. You can also lower pH levels by incorporating naturally acidic organic materials such as conifer needles, sawdust, peat moss and oak leaves. Coffee grounds are also slightly acidic.
How can I make my hydrangeas turn blue?

What gives hydrangea color?
Generally speaking, acidic soil, with a pH lower than 6.0, yields blue or lavender-blue hydrangea blooms. Alkaline soil, with a pH above 7.0, promotes pinks and reds. With a pH between 6 and 7, the blooms turn purple or bluish-pink. To lower your pH, add garden sulfur or aluminum sulfate to your soil.
Does Epsom salt change the color of hydrangeas?
