I may have missed it, but I don't think anyone has mentioned computer-generated labels. Word processing software has templates for labels. These templates can be used to type labels for plants. I use clear address labels (1" by 2 3/4", 30 per sheet (Avery 5660)). The printing needs to be done with a laser printer. The address labels then need to be attached to something such as plastic or metal label. The labels that I've made this way have lasted 3 summers (that's how long ago I started doing it). The print on the label has shown no sign of weathering. Besides lasting a long time, another advantage of the computer-generated labels is that they very easy to read (use a large font). Also, you can put additional information in fine print on the label. --Mark
