Zuzu - if you look at the 2nd picture, you can see yellowing on the leaves.. iron deficiency? They look fine to me as far as height & width if she had major winterkill. Look at my own roses... most of them should be 2-5' tall at their age in ground but I'm lucky to see 18inch to 2' most years because they get killed to the ground EVERY year. And I get huge leaves every year.. cold has nothing to do with leaf size IMO & IME. The NE part of the country has been hit with a long cold season this year and it's probably just going to be a bad growth year this year.
Meredith - Provided that your climate is similar to mine (extreme cold in the winter for a while), but you have snow-cover, your roses look just fine. But the scratches on the canes.. bunnies? I know the
@chelle had bunny damage to her roses before.. (
The thread "Rabbit damage" in
Roses forum). Everything loves to eat roses.
