Aluminum Sulfate For Gardening – Tips & Benefits

Aluminum sulfate works by releasing aluminum ions into the soil, which interact with water to form positively charged hydrogen ions. These hydrogen ions help to lower the pH of alkaline soil, making it more acidic. However, it's crucial to use aluminum sulfate judiciously and carefully monitor soil pH to avoid over-acidification.
