Consulting Rosarian Tips for November:

by Ellen Nielsen

Every winter I fret over the proper time to winter protect my raised bed of hybrid teas, floribunda, and grandiflora roses. I know if the winter is mild and nighttime temperatures have not been 20 degrees or below for three consecutive nights, I will do the winter protection at the Stock Show time, no later.

November 2014 was a different situation. Weather during the fall had been beautiful and many of our roses were still blooming. Weather forecasters had a cold front coming, but really missed on how long it would last and how cold it would be. Unfortunately, beginning November 10th, temperatures plummeted and the cold continued through year-end, frequently sub-zero at night. The damage was done. The roses were frozen before dormancy.

In early January there was 6 inches of snow on the ground and the forecast was for warmer weather. I wanted to KEEP THE COLD IN THE GROUND to help the roses stay in dormancy. The rabbits had been eating the leaves and pruning the canes to 3-4 inches above the snow. I stripped the remaining leaves from the plants, and pruned the canes to fit inside our rose cages. I put sulfur down for general sanitation, piled on compost, and shoveled in snow from the lawn to keep the compost from blowing.

In late April I removed the roofing felt and compost. Only three of the twelve roses looked healthy. The canes had large splits caused by being full of moisture and subjected to very low temperatures before they were dormant. There were a lot of black and sad looking canes, I pruned the dead ones. The remaining nine roses were very weak, with minimal growth if any. Then there was a freeze on Motherís Day, and another the last week of May. We ended up losing Julia Child, Fame, Peace, Liviní Easy, Miss All American Beauty, Sparkle and Shine, and Sevillana. One surviving rose that surprised me was Mister Lincoln. I did not realize it was on its own root but it successfully recovered from its rootstock.

This fall is setting up similar to last year. We are going into November with no significant freezes and roses still in bloom. In hindsight, slowing down rose growth earlier in the fall might be beneficial. Thought should be given to doing the second major feeding of alfalfa and kelp in July rather than August. This would fit most show schedules and promote growth earlier rather than later. Water curtailment could begin earlier in the fall as well, to keep the soil moist into winter but not stimulating growth with excessive water. Deadheading just below the blossoms should perhaps begin earlier as well. There is little that can be done to force roses into dormancy against their will, so letís just hope and pray that we donít have a November like last year.

2015 Roses in Review

Every year, the American Rose Society conducts a survey of roses and how they grow in gardens around the nation.  The national results will be published in a future edition of the American Rose Society magazine.  The results for the Rocky Mountain District (Colorado, Idaho, Montana, Utah and Wyoming) are available now!  The first file contains the results sorted by variety, classification, garden rating and exhibition rating.  The second file contains the comments provided by the reviewers.   



The book, Growing Roses in Colorado, published by the Denver Rose Society is a "must have" for those who want to grow beautiful roses successfully.  Get a glimpse inside the newly revised Growing Roses in Colorado.  Available at area garden retailers and gift shops. For wholesale inquiries please contact Betty Cahill at
