Here in zone 5 I don't really have to do anything to put them to bed. We've had several hard frosts over the last 3 weeks, but in a heat wave of sorts at the moment. [OT] I've been working my Rhipsalis collection into the house, moving them just ahead of the frosts. This takes a lot of work, as they are in hanging pots and I only have a bit of window space for them. So lots of careful thought of what to hang where and on what. My collection has been growing well the past couple of years, so space has become critical. I will have to come up with something better for them for next year.[end OT]
I do try to give the semps a final weeding after the cold knocks down the weeds. That way they are ready for the spring. I also shift the ones I know are water sensitive to a more sheltered location.
