Soil pH is
measured on a scale that runs from zero to 14. A pH of 7.0 is
neutral, with lower values becoming increasingly acidic. Higher
values are increasingly alkaline. Most garden plants perform best
when the pH is between 6.0 and 7.0. Acid-loving plants such as
rhododendrons, dogwoods and blueberries appreciate a soil pH between
4.5 and 6.0, depending on the species.
First things first
approach is start with a soil test so that you know what the pH is
before you begin applying wood ashes. If it is already high (more
than 7.0), or if you plan to grow plants that prefer an acidic soil,
avoid applying ashes at all. If it is moderately acidic (around
6.0), you can safely apply about 15 pounds of wood ashes per 1,000
square feet per year. You could also apply wood ashes to your lawn,
since turfgrass grows best with a soil pH between 6.5 and 7.0.
Again, be sure to start with a soil test and do not overapply the
adding wood ashes to your compost piles, because composting is an
acidic process. If you add too much wood ash to your piles, it can
raise the pH enough to halt the composting process.
