Bonsai Nut
Nuttier than your average Nut
If you took a tree with certain positive traits - say, for example, a Valencia Orange - and continued to graft it over and over again, would the "tree" ever die? In other words, if you constantly created a grafted tree, and then removed scions off that tree to create OTHER trees, and then took scions off those other trees - you are really just cutting off the tip of an ever-growing branch. Does there come a time when the tree just fails? When it becomes weak or the scions simply won't take?
