Tips for Lowering Your Soils pH
To lower your soil's pH level, you will need to mix acidic minerals into your soil. The most popular acidic minerals are sulfur, ferrous sulfate, and aluminum sulfate.
Sulfur can be purchased as a powder in most garden centers. It is thought that sulfur is the most effective of the three minerals listed.
Ferrous sulfate will add iron to your soil. It is not as potent as sulfur, but this mineral can do much to help turn yellowing leaves to a deep green.
Aluminum sulphate will add aluminum to your soil. If you ever switch your garden from an acid-loving plant garden to one that welcomes plants who prefer a higher pH, you will have to add amendments to the soil to keep the plants from acquiring aluminum toxicity.
