Espoma Soil Acidfier

Espoma Soil Acidifier lowers the pH of soils for acid-loving plants such as blueberries and hydrangeas to achieve optimum growth. It turns hydrangeas blue. It is safer than Aluminum Sulfate and is derived from elemental sulfur and gypsum.

Start to apply this soil acidifier in Spring and every 60 days until the desired pH is achieved.

  • Hydrangeas & Blueberries: Apply in the spring to lower soil pH.
    • New Plantings: 1-1/4 cups per plant.
    • Established Plants: 2-1/2 cups per plant 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.
  • Potted Plants: One tbsp. for each 4˝ of pot diameter.
  • Broadcast Rate:
    • Apply 12 lbs. per 100 sq. ft. for each one point reduction in soil pH desired. For heavy clay soils increase rate to 15 lbs. Gradual reduction in soil pH is preferred as dramatic reduction can result in stress.
  • As a Fertilizer: Apply 1/2 cup per 100 square feet (1 tablespoon per plant) around the root zone
