Changing your hydrangeas to an amazing shade of blue does take some time. For larger hydrangeas, changing the color can take a season or two. Donít worry, it will be worth it. So if Beautiful Blue hydrangeas are what you desire, just amend your soil with Espoma Organic Soil Acidifier. Itís that easy!
Soil for Blue Hydrangeas
Many soil acidifiers contain Aluminum Sulfate, which can be harsh and even toxic to some plants, such as Rhododendrons. For an organic garden, safe for people, pets and the environment lower your soil pH levels with Espoma Organic Soil Acidifier.
Before amending your soil and going blue, look at your garden. If there are plants growing near your hydrangeas make sure they also like acidic soil. If your hydrangeas are planted near concrete this may inhibit the process since concrete contains lime.

Reapply every 60 days until the flowers are the perfect blue for you. To grow deep blue blooms, amend your soil pH to 4.5. For a lighter blue, amend your soil pH to be 5. For violet-blue hydrangea blossoms, your soil pH should be 5.5.
