How to Amend pH Levels of Blueberries After Planting
- 1). Test your blueberry soil's acidity. This can be done by taking the soil to a lab or with at-home kits you can usually purchase at garden centers.
- 2). Apply ammonium sulfate if the pH level is above 5.0. Start by mixing a small amount into the soil on either side of the plant and testing the resulting pH level the next day. Continue this process until the pH is around 5.0.
- 3). Apply lime if the pH level is below 5.0. Start by mixing a small amount into the soil on either side of the plant, and then testing the pH level the next day. Continue this process until the pH is around 5.0.
