I winter over some of my container roses, and I sink some of them in the ground--in a raised bed. So far, the putting in the ground has won, although some of the others survived. I put several of mine along the south side of my house-under a rather wide eave, and piled leaves around them. Some died--some lived. I wonder if I put them in dark bags filled with leaves and straw and then left the top open but folded over--would this help. I also read somewhere that you can wrap them with bubble wrap. I will be doing this during the latter part of November. I inserted the five container roses yesterday, but will not be covering up until the end of November. Any comments? Thanks in advance - Barb
