I have pruned mine and it's doing great. I cut off two of the main stems to a height much lower that the plant had before, as I wanted a more bushier look to it. Don't worry, it will actually do it good and it will give out many leaves afterwards. I put some charcoal dust to the cut stem, helps greatly in healing and preventing diseases to the wound. I also got many new cuttings from the old cut stem, which have rooted so I got another plant from them!
