I have a clematis in a 10" pot that's about 6 months old. The clematis has been a very slow grower.

In order to take the plant indoors due to impending hurricane, I need to cut it back, which I realize might not be the best timing, but I have no choice. So....does it matter if I cut it back at the highest point I can (and then cut it back down more in the Spring), or should I just cut it back low now?

Thanks!
