Acid Soil

soils with a pH lower than 7 are considered to be acidic. Several things can contribute to acidic soil. One of them is a lot of rainfall. Other things include the amount of rock under laying the soil. An area with a lot of limestone, for example, would have soil that is less acidic. A pH of 6 is considered slightly acid, pH 5 is acid, and pH4 is very acid. Most flowering plants will do fine in a garden with a pH between 6 and 7, the exception being very acid-loving plants, such as rhododendrons
