Fercrissake ... the OP wasn't asking for debate on what is organic or
not ... personally I'd sprinkle *some* of the ash on my compost heap,
but keep *most* of it in a separate pile, for judicious use in certain
circumstances. Otherwise the "living" nature of The Heap would be
gradually suffocated by the inert ash. In My Most Inexpert (but
nontheless I believe Common Sense) Opinion.

And Franz: you're being too picky. Everything under the Sun is
"organic", unless it is a mineral. But we're not talking about what
chemists talk about as organic or inorganic: we're talking about
holistic gardening ... what would Mother Nature say about "this" or
"that" substance if she found it in your garden? That's the question
that drives us fumblers!

Best wishes all
