This is a purple leaf plum. In the move from FL to TX, the top of the main "trunk" (it was a tiny thing at the time) was broken. Over the last couple of years, it has flourished despite the early break. I'd like to get it to be more of a normal tree shape. I think that if I cut the limb marked that I'll end up with a better shape. I also don't want to kill or greatly weaken the tree. Assuming this cut wouldn't be too traumatic for the tree, when should I do it, now, in the fall?

Thanks
