I think I killed it. (and I have a camera!)
I just know I've killed it! But I'm not about to give up on it... Is this how it's supposed to look as it goes dormant? It looks quite dead to me, but I'm used to trees changing colors as they go dormant, so I don't know for sure.
Since I thought it might not be cold enough in the basement, I moved it into a much colder area, and last I checked (near 10:00) it was at 31 degrees... I can only imagine how cold it might have gotten over night, I've never checked the temp in there early morning. The leaves are all wilted but not crispy, none have fallen off and only one has a brown tip on it (has had the brown since before it's winter, but it got a tiny bit bigger) they don't seem to have changed colors aside from that. I'm not sure if pomegranates do that, but I thought it better to be safe than sorry. I've moved it back to the basement window for the night which is currently 50 degrees, and likely a good bit warmer than 31 even at night.
Should I move it between window and cold room daily so it doesn't get too cold at night? (that is, of course, if it's not dead yet...)
