overwintering inside - leaf drop
I'm trying to overwinter inside and have moved some of my plants to an attic room with a small window (very small) that stays at about 50 degrees (well, except for our crazy 70 degree days in November). The plants have been slowly dropping leaves. In fact, they look like they're all going to drop. Is this normal? Can they go dormant and leafless for the winter? Or should I pull them out of the room and switch them downstairs where it's warmer, but better lit? The sage in question are Pinapple, chiapensis (which is holding it's leaves best) and holwayi. Help!
