It is that time again to begin forcing my Plumeria into dormancy. I have now pulled/dug all my Plumeria out of the ground or large pots, rinsed off the remaining soil, and stacked them under a large oak tree. I will leave them there for 2-3 wks so that they can begin dropping their leaves, and then, before the first frost, I will bag them all up in large, black contractor's bags and put them away in closets or on my enclosed back porch to overwinter. Before bagging I make sure that each plant is properly labeled so that I know what's what when I replant them in March. I have followed this schedule for a couple of decades and it seems to work well. I live in NE Mississippi and it will usually get into the mid to lower teens here several mornings and drop below freezing many days during the winter months. It is a chore to bring in all my tropicals, but I have no choice.
