Absolutely, Carol. I always tell them that. I have phal. with old stems blooming, new stems blooming, and keiki's on old growth as well. I cut off the really dead part, that will be brown and brittle, but cut just above what is still green/purple color on the stem. Good point. As I say, numerous books have been written about growing orchids and a thread such as this is a drop in the ocean of information.
