Best Labeling for Grafts
As I've been playing with learning to graft the last couple years, I would do one graft per tree, then mark on my map of trees what the grafts were.
Then, I got to thinking a little and wondered if there were a way on grafts that take to "tattoo" the branch to identify it permanently as a graft and what the variety was? The bark is always growing, so an ink type tattoo would just disappear? Trying to score the bark would have to be extreme to create something that would last?
So, what do people do? Use metal tags they can write on and hope they don't become unattached or stolen by birds? Or do you just let them go after a few years and no longer identify the graft?
