Hi! I'm in northern VA, not the greatest place to overwinter oleanders. I have two in pots that I generally bring inside in winter. However, I do know that oleander is somewhat cold hardy. I plan to bring it inside only when it gets seriously cold here. Right now they are sitting outside on a porch that is sheltered from wind and frost. Will this be enough, generally, until we have temps that get below thirty? My sunroom is so crowded already with plants that really can't take the cold, like bougainvillea and ficus.
Thanks for any help,
