EarthKind Rose Trials
Evaluate 26 shrub rose cultivars to determine which cultivars have the best landscape qualities in our region. Roses will be evaluated for winter hardiness, disease and insect tolerance, percent bloom, bloom diameter, plant architecture, and fragrance. Roses were watered during the year of establishment only, no synthetic fertilizer, fungicide, or insecticide was applied to roses. No winter cover or supplemental water was applied to roses.

Cultivars of shrub roses were established at Centennial Dog Park in Moorhead during the 2008 growing season. Due to poor establishment many cultivars were replanted in 2009. Data was collected starting in 2009 and concluded in 2012, beginning in May each year to determine winter survival and monthly thereafter to determine disease and insect tolerance, percent bloom, bloom diameter, plant architecture, and fragrance.
A plot tour was held in 2011 and 2012 to showcase the trial to the public. In 2011, the trial had airtime with Mick Kjar on AgNews 890 AM. In 2012 the rose tour was covered by The Fargo Forum and WDAY News. In 2012, three presentations were given on the Northern Earth-Kind® Rose Trial. Presentations were given at Green Thumb Gardening Expo, Fargo; High Tunnel Workshop for the Home Gardener and Commercial Grower, Moorhead; and 11th District Horticulture Society Meeting, Georgetown.Last updated 10-15-2009
