My Plumeria are over 14' tall and the gusty winds from the recent tropical storm did a number on them. I can not see the flowers on them at the height they have grown and was going to wait until spring and cut them back. Would it be ok to just cut them back now?

Scott, it's ok to cut them back now but your chances of rooting the cuttings at this time of year are reduced. If you can wait that would be better. If not - there is nothing wrong with cutting them now.
