Rose Rosette Disease: An Update

We have all seen the unsightly stands of Knockout Roses planted in median strips and occasionally, our home gardens, that have strange, deformed stem and leaf configurations.  This anomaly, known as Rose Rosette Disease, attacks our hybrid teas, climbers, shrubs and all other types of roses.  Dr. Mark Windham spoke at the U.S. National Arboretum. He is a leading researcher on Rose Rosette and provided an update on this disease that is a threat to the gardens of all rose lovers.

DR. MARK WINDHAM discussed current research being conducted on Rose Rosette Disease (RRD), as well as the latest research identifying disease resistant varieties. The American Rose Society Research Endowment Trust identifies Rose Rosette Disease as the greatest threat to the future of commercial and recreational growth, and the enjoyment of roses. In 2012, ARS selected Dr. Windham to head a three-year study about the management of RRD. The objectives were to determine how rosarians manage RRD in their gardens and identify best practices
for RRD, besides eliminating plants with symptoms. Dr. Windham also believes that roses have lost popularity due to growing public aversion to the regular use of pesticides in home gardens and has therefore been developing a list of roses that homeowners can successfully grow without reliance on chemical control tactics. Rose Rosette will continue to be a threat to our home gardens for years to come. In a grant fully funded by the USDA National Institute of Food and Agriculture’s Specialty Crop Research Initiative, Dr. Windham is included in a group of 18 scientists concerned with Rose Rosette research (housed at Texas A & M), that continues to lead research on Rose Rosette Disease.

Please Show Us Your Garden

Using visuals, Tina Hochberg, Joe Covey, and Reed Abrahamson, all  members of the Potomac Rose Society, discussed the evolution of their home gardens, featuring their experiences in adding and maintaining roses. Presenters included examples of personal successes and challenges, as well as plans for the future. In this popular annual presentation, participants picked up tips for successfully beautifying their DMV area garden.
