Homeowners and gardeners alike are interested in soil pH because soil pH directly affects the growth and quality of many landscape plants by influencing the chemical form of many elements in the soil and soil microbial processes. This 3-page fact sheet explains soil pH and provides strategies for Master Gardeners and homeowners to make the most of the pH in the home landscape or garden. Written by Amy L. Shober, Christine Wiese, and Geoffrey C. Denny, and published by the UF Department of Soil and Water Science, May 2011.
