Very good question Chris. I don't know but since I have several in the ground around here I'll try a "thorn" and see. Are you talking about all the way flush with the trunk or just nipping the tip?

You can, but it's a zero-sum exercise...I tried removing them for a while, realized I'd never keep up, and just learned how to work carefully with mine; thorns and all.
