I have a plant of XYLOPHONE JAZZ that for some reason became covered with rust and I simply could not get rid of it. So I ended up doing something that was extreme, but Guy Pierce said he does this whenever he sees a plant with rust -- I cut it back to the ground! And lo and behold, it came back with absolutely no rust! That was at least three years ago, and my XYLOPHONE JAZZ has never had rust since, so that is what I will do if I find it agaiin.
