Ok I have to admit I got my hibiscus from a plant shop just because I thought it was pretty and I knew absolutely NOTHING about them except that they are tropical. I got an answer from Nikki about my first question "how do I get a bushier hibiscus" and her answer was really helpful. (THANKS! :)) But now I just want to make sure I understand. A hibiscus is an actual BUSH. . . not a plant like my peace lily or my gerber daisy? So it needs to be trimmed like any other bush or hedge? And also the article said trim a few inches from the node. What's a NODE?
