One of the ways to protect roses for the winter is to be sure they go completely dormant. To accomplish this, stop fertilizing early enough so growth slows down. No fertilizer should be applied after August 15. To further encourage dormancy, stop dead-heading or cutting flowers after October 1 and allow the plant to form hips.
How to keep roses from breaking dormancy?
Second, cones need to be well ventilated to prevent heat build-up on the inside during sunny winter days. Cut four to five 1-inch holes around the top and bottom of the cone. These holes will aid in ventilation and keep the air inside the cone from heating up, causing the rose to break dormancy.
