I have a tree rose in a planter. I am wondering how to care for it for the winter. Is it safe in my garage or will it be too cold, given the severity of Minnesota winters? Should I wrap it somehow? Should I prune it back? When should I move it? Thank you for your assistance

Some varieties of roses can survive outside over the winter. This would be true for roses rated for growing zones 4 or lower. However when roses, or really most plants, are in pots, their survival outside over a Minnesota winter is rather bleak. So it would best to bring your potted rose inside for the winter.
Here are some sites that will provide you further information and guidelines for doing this:
As you read through the above, two primary steps are obvious. First, it is important that you trim your roses back to encourage the plants to enter into a state of dormancy. Secondly, although inside, the roses should be stored in a cool, dry area. This is important as it will prevent your roses from breaking dormancy too early.
