I actively compost pulverized oak leaves mixed with coffee grounds. In the winter, I get a few buckets of ash from my fireplace. Is it OK to throw the ash in the compost?
Where you live the soil is very alkaline and adding ashes makes the soil even more so. Green oak leaves are very acidic but dead leaves and leaves that are breaking down are only slightly acidic to neutral. Coffee grounds are usually slightly acidic with a Ph of about 6.7 but depending on the coffee grounds can be neutral. In Boerne you need all of the acid you can get and hardwood ashes here have a Ph of about 10, so adding ashes is not a good thing at all.I actively compost pulverized oak leaves mixed with coffee grounds.

I on't think so throwing ash in a compost is a good idea.
