I was wondering....when plumeria cuttings have started that fungus rot (I
think it is because of fungus) on the rooting end, that is, it is starting
to get blackened and "mushy", will the cutting still root? Or should I
re-cut the cutting above where the blackening begins, let it sit for some
days until a new callous is formed, and then plant? What about if I just
cut off the blackened part and immediately plant it? Will the lack of a
callous on the end prevent it from rooting?
