Mary Lee, I live in Starkville, MS and I pull all of my plumeria up around the middle of October and allow them to "rest" under oak trees for a couple of weeks so that they lose most of their leaves. I then hose off the remaining soil from their roots, remove what leaves are left, and put them all in large contractor bags. The bags then go in closet(s) and under a bench on my (now) enclosed porch. They will all overwinter bare root from November till March. Three years ago I stored most of the plumeria out in our unheated (though enclosed) garage, and lost all of them. Lesson learned. Ken
