For Hydrangeas and blueberries: Apply in spring to lower pH. For new plants use 1 1/4 cups. For established plants use 2 1/2 cups spread evenly around the plant out to the drip line and water well. Repeat in 60 day intervals until desired pH or bloom color is achieved.
Broadcast Rates: Apply 12 lbs. per 100 sq. ft. for each point reduction in soil pH desired. For heavy clay soils increase rate to 15 lbs. Gradual reduction is preferred as drastic reduction can result in stress.
Potted Plants: Add 1 tablespoon for each 4 inches of pot diameter.
As a Fertilizer: Sprinkle 1/2 cup per 100 sq. ft. (1 tablespoon per plant) around the root zone.
