I would not use fire ashes on plants or compost due to the likely risk of
poisons from burnt coal that would build up in the soil over time.
I am not certain if such toxins would exist from ash of known woods. Perhaps
others could advise?

Is there a compelling reason to use use or not use fireplace ashes in my
compost pile?
