Can wood ashes and barbeque ash be used in the compost pile?
Wood ashes act as a lime source, and if added to compost should be used only in small amounts (no more than 1 cup per bushel of compost). As with adding regular lime, excessive amounts of wood ashes result in loss of nitrogen from the pile. Charcoal is just a partially burned form of wood. So long as no other chemicals have been added (check labels on packaging to be sure) barbeque ash should be a safe compost addition.
