Help! I cant find Vermiculite, Peat Moss, or a source for saw dust to cover my Dahlia bulbs for the winter. Is there anything else I can use?
I'm not sure why you are using anything in the bottom of your chimnea. i am guessing maybe it's something to do with it being terra cotta. If so, vermiculite is volcanic ash and will be ok for fire. If terra cotta, keep water from getting inside in the freezing temps, it will crack.
