Hello! I posted this elsewhere but haven't received an answer and thought maybe this might be a better place to find out...

I'm starting to collect up on some plumeria's here in zone 9b and on the few occasions the temp drops I found I don't really have as much space to bring them indoors anymore. Plus the big one is hard to drag inside. I can't afford a big permanent structure, but was thinking one of those portable ones might work since we don't really freeze much here in Orlando? Any suggestions? Or would just covering them be fine?
