From what I've read, I should be able to cut the top off and plant it, and it will grow. However, I've only been really working with plants for a year or so, so I'm not exactly sure where to cut it.
Also: I'm so sad this has happened! I just got the plant and intended to re-pot it.
I'm going to try to add photos. In second photo - is that focal point, at that leaf node, the area I should cut it at?
