How do I lower the soil pH for blueberries?
Home gardeners can lower their soil pH by adding sphagnum peat moss to the soil. Sulfur can also be used to acidify the soil. Sulfur should be incorporated into the soil a year before planting as it reacts slowly with the soil. Aluminum sulfate should not be used to acidify the soil as large amounts of this material can be toxic to blueberry plants.
