Most garden soils have a pH between 5.5 and 8.0. This number helps you determine when and how to adjust your garden soil’s pH level. If the pH level is below 6, the soil is too acidic, and you need to add ground limestone. If the measurement is above 7.5, the soil is too alkaline for most vegetables, and you need to add soil sulfur.

Technically, pH is a gauge of the hydrogen-ion concentration (potential Hydrogen) in a substance.For the gardener's needs, it is enough to know whether your soil is alkaline or acidic because certain nutrients can only be accessed by plants when the soil pH falls into an acceptable range and no amount of fertilizer is going to improve their health until the pH has n adjusted. So for a soil pH to change from a high pH of 8 down to a pH of 5 it is not a factor of 3, but because the pH Scale is a logarithmic scale, it is a factor of 1000. Therefor one has to add 1000 times more acid to bring down the pH. A pH of 6.5 is just about right for most home gardens, since most plants thrive in the 6.0 to 7.0 (slightly acidic to neutral) range. Some plants ( blueberries , azaleas ) prefer more acidic soil, while a few ( ferns , asparagus ) do best in soil that is neutral to slightly alkaline.
