With the drought, I am a bit apprehensive.
Last winter I lost, at this point at least 5 roses; in over 40 years I have been working with them, including years with -40 below, I never lost more than two and it was usually due to uncovering them too early in the spring.
Cold dry winters are horrible for perennials, and usually when I uncover the roses, the bottom 3 inches of leaves are a sloppy mess.
This year they were damp and that is about all.
When I roto-tilled my South garden last week , I had dust blowing from the tilled dirt.
I found a couple of years back, continual watering with a hose is not the same as rain.
