Okaay! The sun porch sounds like just the place for overwintering your brugs, Brian! You don't have to break the bank keeping it at tropical temperatures, just keep it about 55 or 60 at night and they will be happy and grow slowly.
Too bad about all that snow, I know this was a nasty storm up your way. Yesterday when I looked at the weather map it stretched all the way from Cuba up to Nova Scotia!
We had temps in the low 40's last night so my brugs will be dormant now for a month or two. They were all in full bloom, too!
We usually don't get temps that low until January. Saddest of all is that it will now be warm and lovely for the next week. But once they get chilled, it takes a while for them to bloom again. They keep growing, slowly though.
