Consulting Rosarian Tip of the Month



The average first frost is around mid-month for much of the Front Range. Below are a few easy tasks to assist your roses as they bid farewell with their last blooms of the season.


  • Continue Integrated Pest Management (IPM) monitoring through early freezes.
  • Deep water prior to predicted hard freezes to lessen damage to dry roots.
  • Remove any blooms just below the flower.
  • Continue to remove basal breaks – these new growths cannot mature before winter, and will only drain energy the plants need to survive until next May.
  • Keep beds clean by removing old leaves infected with black spot or rust; trim off mildew or spray with a product like GreenCure®.
  • A 2 – 3 inch layer of mulch will maintain soil temperatures. Keep mulch an inch or two from the base of the cane.
  • Growing Roses in Colorado (GRIC) has a wealth of information on care of roses, find the book at area garden centers, gift stores or order from this website.
