For a while I've been thinking of ways that cascades could be grown without wiring. One way I thought was to grow them out of the bottom of a pot somehow, but the details of that venture never seemed to crystalize and I was left with a vague grand idea.
That was until I found this article on Instructables:

Since this project is cheap and easy to make, it might be an idea to adapt it to growing trees. Any thoughts on growing trees upside down for most of their lives?
