Container gardening is very popular but container plants are extremely vulnerable in winter, even if they are hardy when planted in the ground. One option, of course, is to bring them inside but that is often not convenient or possible. I have adopted a successful method of protection for my roses in containers; it can also be used for other plants. In December, Garden Centers and such will be selling evergreen conifer branches for inside holiday decoration. White pine branches work well for outdoor protection. Cover the plants top to bottom with the branches and tie them in. Move the pots together in a group, and that’s it. Unlike other methods (as for example, the use of synthetic cones), conifer branches allow for air circulation, and they look good and smell good. (Check out the photo for the looking part). And, most important, this works.
