I have a whole bunch of young plumerias, from newly rooted to 4 ft. high,
all in pots. Leaves are starting to turn yellow from the cooler fall temps.
Am in Zone 9. Most winters here, there are only a few days of freezing
weather, and not much below 32 deg. at that. There is no indoor area
available that could be used to protect them, they are just stuck outdoors
in the back yard for the winter. Will a freeze kill them? I heard they are
pretty delicate tropicals. I could only cover them with plastic or a tarp,
if this would help.
