I mjramom! I am in south Texas Zone 9a near Houston. I leave my potted plumeria alone in the winter. I don't fuss with them much. They only get water if they have leaves, which are about 3 of my NOID varieties. All my repotting and other plumeria activity happens in the spring. DutchLady is full of the best information here! You will learn a lot from her.
Are you plumeria (and other plants) protected from the cold blast we are in for tomorrow??
