You firewood burners. What do you do with your wood ashes? I've got a pile from last year. The outside wood furnace using mostly poplar or ash about 10 to 12 cords per year in the northland here. I've also used them on the asparagus beds mixed with manure. What wothwhile use do you put your wood ashes? What if a pile left out is leeched from rain? What about making lye for soap using wood ashes, or does that make any sense? Mixing wood ashes with compost? Anyone do this, and what amounts?
