Angie,
Are you excited that you may have a white Christmas?
We had a warm spell today. It finally made it up to around the freezing mark and it was sunny so I'm pretty sure we had a little bit of snow melt which will surely be of benefit to those new roses.
I'm not so sure I'd know when peonies need dividing. I'm not much of a peony person, though I do enjoy them for the few days they look good. Our blooms tend to be prematurely destroyed by heavy rains.
It was impossible to plant anything here this summer as well - just way too dry.
