I have only rekindled this hobby since last June. I had mine sit on a windowsill from June until mid- Novemeber, so it experienced a natural decreased photoperiod, while the temp decrease was not as pronounced, getting into the 50's. I then it themhome from work and placed them in between the inner and outer kitchen windows, so it would experience more coolness but be buffered by the kitchen. It still wasn't cold enough. So I put them in the screned in porch. It got colder for them; so much so that the media froze one night. I know they can take light frosts, but we were in the midst of a cold snap, here in Reading, PA. Then I moved them to the butter keeper, where it was cold but stable for most of the rest of its dormancy. Then back to the lab fridge for another couple weeks, followed by the cool window sill, before sending them outside. All stopped discernible growth and 3 o 4 plants flowered. What I am getting at is that my area is just a little too cold to leave ouside for 12 months, without significant mulching. Should I clean them off and put them in wet paper towels when they have already fallen asleep or just before then?
