I have a spot where I put all my losses when I find a tag...it is like a little graveyard! For me it is more important that the plants are marked with something that I can grab in a hurry because I always seem to forget where I stored my more permanent tags. So lately I have been using plastic knives and forks, and writing on the part that goes into the dirt. Even if I have a nice tag for one, eventually that iris will need to be divided, and that is when the id problem starts for me...
