It moves slowly through the soil and, thus, gives the roots something to keep them strong during the sometimes long and hard winter and will help the rose bush survive the cold weather .
A rose bush’s inherent hardiness contributes to its ability to withstand subfreezing temperatures. For example, old garden rose varieties can tolerate extremely cold winters, whereas more modern hybrid tea roses need considerable winter protection to survive the cold undamaged. Roses in the Oso Easy® series have been bred for cold hardiness.
If you live in a place where temperatures drop below 10 °F (−12 °C), your roses will need some protection to survive the frost. Once the roses freeze, it’s best to keep them frozen to protect them from temperature fluctuation.
Many of your roses could still be alive under the snow. You don’t want to prune anything off until they are clear of snow and growth buds have started to fatten. That’s when you’ll be able to tell what is dead and what is viable cane.
