Finally after years of having them, I have about a dozen that I've been moving in and out of the house each winter. This year I still have them on my front porch and some are Finally! sending up spikes. My temperature can get to the low 30's occasionally then go up to 80+. Should I just keep them on the porch and cover with frost cloths and if so at what temperature should I cover them. Tonight may be upper 30's. Or should I put them in a cooler room with an easterly window? I would really like to enjoy the blooms but don't want to shock them and have the flowers drop.
