Color Me Pink™ from Bonide® raises the pH of the soil to the right pH (6.5-7.0) for pink-flowering Bigleaf Hydrangeas. A neutral to acidic pH can make these shrubs bloom purple instead of pink. To raise the pH, work 3 scoops per plant of Color me Pink™ into the backfill soil for new plantings. For existing plantings, apply in spring, working 6 scoops (1/2 cup) into the soil around the root zone while staying away from the plant stem. Water well after applying.
Measuring scoop and instructions for use included.
