Is this save-able? Or if all the leaves fall off with it regrow?? I’ve only had it for about a month and recently it’s been very cold here (-16 degrees) the leaves started falling off and now it’s droopy. It was in my living room with a south facing window but it was so much colder in there that I brought it upstairs to my room which is bright indirect sunlight. I have humidifiers and a light but I don’t know if either of those is helping at all. Please help!!
