Woke up to about an inch of snow this morning, and the low tonight is supposed to hit 23. This will be my first winter in this climate with these plants, previously they spent a couple years outside year round in Houston. But it gets too cold here to keep 'em outside in the winter, so my plan was to keep them out for a few frosts to kick them into a hard dormancy.
Thing is, the low temps previously had been in the 50's and upper 40's. Suddenly we have a few days in the 20's and 30's. I don't want to kill them by keeping them too cold, but I don't want to pull them in too early before they go completely dormant - I'm going to have to keep them in a dark garage, thus the need for a deep dormancy.
