I totally agree. I was busy last year. By the end of the season when I had time to replace those plastic tags (written with UV resistant permanent marker, no less) with permanent tags, several tags were too faded to make out the names. I’ve about a dozen “guess what I am” trees as a result.
I’ve also learned that it’s the quality of those plastic tags, rather than the quality of a marker that makes a difference. (I pretty much use the same markers). Some tags that have quite “oily” surfaces cause letters to fade within one season. I have some tags that I wrote on since 2015 that the names are still clearly legible.
I went back to my purchase order and ordered from the original company again this year. I’ll see if the quality of the tags from this company is as good as it was in the past.
