but I've heard you have to be careful, like, if you use started logs (chemicals) don't use the ash from that sort of fire.
can anyone tell me, I have to burn rose and iris trimmings if it has leaf spot. that's about the only things I burn outdoors. can this be used, or is the spore still viable? I know never ever to compost these trimmings, as the spore survives in the compost.
