Winter mulching isn't used to keep the ground warm, it's meant to keep the ground frozen. Frozen ground won't kill hardy plants, but repeated freezing and thawing will. The expanding and contracting of the soil can push plants right out of the ground.
A layer of snow is excellent winter mulch for plants. But if there is no snow, here are some other ideas for insulating your plants.
