When to take the rose collars off to "de-winterize"

In Milwaukee, WI, we have had a relatively mild winter in terms of cold & snow. Temps this week have been in the 50s & low 60s for a few days. I don't want to take the collars off too soon in the event we get a freeze yet. In Wisconsin, it is so difficult to know with our crazy up and down weather. Can anyone recommend when to remove the collers & start pruning? Thanks. Need help please!
