@Dutchlady1,
@AnnaZ recently sent me a T-Mail telling me that she is "baby-sitting" a 5' plumeria for a friend (Anna has a GH). Anna is in WI. Anna says that the tree has not lost leaves over the fall/winter months and asked why. I don't have an answer. I pampered my six trees in the S room and ultimately, most of those leaves still were lost.
Hetty, why wouldn't Anna's tree have lost the majority of its mature leaves?
