Winter care varies with the different climates so local gardeners advice is invaluable. However there are some general guidelines to follow. Rose bushes die or die back over the winter from cold drying winds, changes in freezing and thawing and from cold temperatures to the bud union. To protect the bud union mound up soil or a mulch to about one foot high after the first hard frost. Do not cut canes in the fall or give nitrogen fertilizers as both stimulate soft new growth which will be killed. Long canes on bushes or climbers can be tied to prevent wind rock. Container plants can be moved inside to an unheated space when their leaves fall off and a little water should be given monthly to prevent drying out.
