Hello. I am looking for advice on Ficus Benjamina. In the spring we procured two large beautiful trees in pots. They are approximately 7-8' tall. Have done very well outside on the north side of the house next to our hot tub. Being as big as they are there is no way these guys can come inside. Just won't work. Will they survive the southeast Ga winter? Will they lose their leaves until spring? Is there something I can do to protect them outside until warmer weather? I know it's not real close to freeze time, but I would like to have a game plan for that first frost warning! Thanks!
