  1. it’s my understanding that the color of hydrangea blossoms is dependent on the pH of the soil.
    “For most bigleaf hydrangea cultivars, blue flowers will be produced in acidic soil (pH 5.5 and lower), whereas neutral to alkaline soils (pH 6.5 and higher) will usually produce pink flowers. Between pH 5.5 and pH 6.5, the flowers will be purple (see image at left) or a mixture of blue and pink flowers will be found on the same plant. ” USDA

  2. My father in law often pees on his hydrangeas because it supposedly changes the pH and makes the blooms darker…not sure if it works, but men love to pee outside so, why not give it a try?

    I love San Francisco btw…my son was born there…glad you had a great trip!
