Garden soils that are either too acidic or alkalinemake it hard for plants to absorb the nutrientsthey need.
Soil pH is measured on a scale of 0 to 14.
If youre growingacid-loving plants such as blueberries, you may not need to adjust your soil pH at all.
Quicklime, on the other hand, is not suitable for use in garden soils due to safety issues.
4 cups of wood ash equals one pound of aglime.
