Keeping your roses healthy throughout the summer and fall will give them a better chance of surviving winter weather. After the first frost of the season you can cut back the longest canes partway so they are less likely to whip about in the wind. (Additional pruning is typically done in the spring.) Then pile a cone of garden soil over the base of each plant, making it about a foot tall. Also mulch over the surrounding root zone with about six inches of organic mulch. Do this in late fall -- November or December when the plants have stopped growing and the ground is frozen. In the early spring, begin gradually removing the soil from the base of each plant. This will allow it to wake up naturally with the season. When new growth begins, trim off any winter damaged canes, cutting back to live wood, and then pruning for shape or to thin out the oldest canes.
