For years I made labels with Dyno label maker and had little trouble with them fading or falling off. Couple of years ago made all new labels using clear address labels made on the computer. Make sure you use labels for laser printer so they do not wash off in the first rain storm. Have not had any problems with them as yet. They look nicer than if I labeled them by hand. I think several other members in Midwest use this type of label.
A few years ago I started burying a label made from blinds using marking pen writing on both sides. Am having problem with them heaving in the winter. Maybe should make them shorter and plant deeper.
If I plant a miniature in a pot I write on the outside of the pot and also place a small plastic label in it.
