This crazy weather has me worried

50 degrees, 30 degrees, 40 degrees now predicted10 degrees. This is a recipe for disaster when it comes to long term survival of the tender roses in my garden. It's times like this when I wonder why I try to grow tender roses in a climate where roses do not want to survive. I do all the heroic things to increase their chances for survival, then nature throws in wild swings of temperature that you try to plan for. Time will tell the effects of such variations.
