Rick, another excellent article!
Grafting, that's taking things to a level way beyond an impulsive and virtually effortless swipe of a pruner (to make a nick.) My next level was going to be to jam a little pebble into the nick, kind of like air layering without the extra effort of surrounding the nick with moist peat and covering in plastic. It's not like I need more of the Dracaenas I already have, I surely don't. But performing weird plant manipulations, then seeing what happens, is a lot of why I get up in the mornings! That's how the nicking that I've done manifested, not necessarily in connection with the goal of more plants or branches in mind. Just unbridled curious enthusiasm, and the desire to have "something to check" besides just looking for pests or thirsty conditions.
And, I didn't come up with the idea, not at all. So if it was very likely to cause a new branch on Dracaenas, it would probably be a well known, common practice with these popular house plants. Where on the trunk could be a factor in the likelihood of results too, whether it's old wood, semi-woody, or farther up in the newer, greener material.
