Private Garden Tour and Reception at the Smithsonian Katherine Dulin Folger Rose Garden
On September 9, 2018 a group of rose enthusiasts braved the rain for a tour of the recently renovated Katherine Dulin Folger Rose Garden. Smithsonian horticulturist Shelley Gaskins conducted this tour as a follow-up to her standing-room only presentation in November 2016 on the renovation of the garden and the decision to include disease resistant rose varieties along with companion plantings to attract beneficial insects. Many of the new plantings are now in their second year, so this was an excellent opportunity to view a wide selection of healthy varieties and get new ideas to incorporate into your own gardens. The Katherine Dulin Folger Rose Garden is located on the National Mall at 900 Jefferson Drive, SW, Washington, DC, in front of the Arts & Industries Building and East of the Smithsonian Castle.
Making Beautiful Container Plantings with Roses
You can grow beautiful roses even if you don’t have a big garden and perfect soil! Roses are ideal for growing in containers, creating a fragrant, floral spectacle on decks and balconies or alongside paths and entrances. The Potomac Rose Society welcomed Eva Monheim - Horticultural and Environmental Consultant and Educator, who helped us learn all about Growing Roses in Containers. Eva Monheim has studied horticulture at Penn State University and at The University of Reading in England and is former Assistant Professor of Horticulture at Temple University. She has taught at the Philadelphia Flower Show, New York Botanical Garden, The Barnes Foundation, and the Morris Arboretum.

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.
