Protecting Shrub Roses for a Minnesota Winter

Although our Flower Carpet Ground Cover Roses from Monrovia should overwinter well, I protect them in the fall.  After cutting back the roses to 6 to 8 inches, I cover the roses with a mound of oak leaves held in place with some sections of chicken wire and a few pavers or small logs.  Oak leaves are the best because they do not rot and they are easily raked away in the spring.
