For soil or potted plants

It’s based on a formula that is over 57 years old, an industry standard for many years, first published in 1936. The formula can be used on most all hydrangea including the shrub and climbing-vined types.

The formula works by lowing soil pH to encourage color change in plants preferring acid soil.

Pink and Red forms often turn Blue or Purple in acid soils.
