Our Soil Testing and Soil Testing Labs web page provides information about soil testing and has a list of area labs to consider using. We can help to interpret test results if desired.

Fireplace ash can be used in the home landscape, with caveats like not applying it to acid-loving plants like Rhododendron or Blueberry (as it can raise pH), especially since the latter can be sensitive to excesses of aluminum, which becomes toxic to their roots at some concentrations. Having a laboratory soil test performed first on the soil in the area(s) you intend to distribute the ash will help you determine how much can be applied without altering the pH too much. More information about the benefits and risks of using wood ash in the garden can be found on the pages linked below:

• Wood Ash in the Garden -- Michigan State University Extension
• Using Wood Ash in the Home Garden -- University of Wisconsin Extension
• Are fireplace ashes good for my soil? -- Oregon State University Extension

Extra wood ash can probably be disposed of in the trash as long as it's completely cooled-off first.
