Marilyn, I have noticed if I have used an eraser on the tags that they deteriorate very fast.
If I haven't used an eraser on the tags that they will lasted all summer. I wonder if there is some type of coating on the paper tags that's being removed by the eraser. I also thought about putting a piece of clear tape over the writing. This last summer was the first time I've tried to do any of my own crosses. I also tried to tie a different colored ribbon to each iris to help find the pods faster. One color was for crosses I made and another color was for bee pods. I also tried to write information on the ribbon which was a disaster. By the time I cut the iris pods off the ribbons were so faded you couldn't tell the colors apart other than where the ribbon was knotted. The other thing I tried was to photograph the pods with the cross information in the picture.
