I am in south Texas. I have many young plumeria all started from cutting last sping (2019). They are all in 2 gal pots. Just had fisrt strong norther.....temp got down to 41 deg briefly. Seems like they will survive that and this will probably make them drop leaves and go dormant. There is not room in the garage for all those pots to over- winter them. I believe i heard they can be plucked out of pots, soil shaken off roots, and piled up dry in an indoor location to save from freezing weather. Is that right....and what happens if I pull them out of the pots right now before they have dropped their leaves?
