The rest of us must deal with the problem of winterizing roses. Winter hardiness of roses is subject to many variables, mostly the micro-climate of your garden and the fluctuations of the weather.
Some varieties can withstand the winter better than others.
Be assured there is no one right way to protect roses from fluctuating temperatures and icy winds. If you have never protected your roses bushes and have lost few or none, then there is no need to start now, except for new bushes planted last spring. How much protection your bushes need will depend on their particular spot in your garden. Bushes planted near the house are already protected to some degree. Spots in the garden that are sheltered by shrubs or walls from icy winds will also require little protection.
