I live in northwest indiana, so we get usually harsh winters. Id like to stock up on weeds if its feasible. If I were to start collecting them, and dry them, would that work? And what kind of process would that be? Just setting them out until they are dry, and then storing them in something? I plan on planting a small indoor garden for them so my sulcata can graze in her indoor pen, however I've killed a spider plant before. So I would like to have something to fall back on in case my black thumb takes over. Anyone else do this have any pointers?
