The addition of lime to the soil around the hydrangea wonât change the flowerâs color overnight. Depending on the soilâs texture, it may take months or even up to three years, according to Reeves. Monitor the soilâs pH twice a year.
Q. How can I change the color of my hydrangeas. Hydrangeas are fascinating in that, unlike most other plants, the color of their flowers can change dramatically. It would be nice if one could change the color of hydrangeas as easily as it changes in this little picture.But for most of us, it is not easy.ne can rarely change the intensity of a color (how strong or pale the color is). The intensity develops for a number of reasons: the heredity of a particular hydrangea variety, weather conditions (hot or cold, humid or dry), health of the plant, and possibly other natural factors.
