While many plants grow in neutral soil, there are plenty of acid loving plants, including some flowering perennials, shrubs, and ground cover species, that prefer soil with a pH value of less than 6.5.
Neutral soil falls between 6.5 and 7.3. You can increase the acidity of neutral soil with some soil amendments, such as sulfur and compost. In areas with alkaline soil, growing acid-loving plants in containers is best.
