My Yucca plant is about 7 feet tall and has grown straight up with no other branches. The bottom 4 feet or so is woody stem with no leaves. I am wanting to cut it back because it has no more room to grow and is starting to curl along the ceiling. If I cut it back, will it die? I would like to somehow create some new branches and my other yucca plant has done this on its own. How can I get it to branch out without killing it? If I cut if back, will it die? Thank you.
