Blueberries – Aluminum Sulfate

Q: Are you supposed to put aluminum sulfate on blueberries at this time of the year?

A: Aluminum sulfate is used to lower the pH of the soil around blueberries because they prefer a relatively acidic soil, pH 4.2 to 5.2. You can have your soil tested now to determine if you actually need the aluminum sulfate on your blueberries. Details at www.georgiasoiltest.com.
