Replacing Roses Affected by Rosette Disease
Time after time designers, landscapers, municipalities and homeowners overuse certain plants to the point of making them a monoculture and then an insect or disease comes along and wreaks havoc. We’ve seen it with elm trees, ash trees and now we are seeing it with landscape roses. Rose Rosette Disease (RRD) is now knocking out landscape roses particularly in the South. The virus is spread by a tiny eriophyid mite that has an association with multiflora rose, so the disease is likely to intensify throughout the Midwest in states where multiflora rose has naturalized. At the moment there is no cure for Rose Rosette Disease, so infected roses need to be destroyed and replaced with something other than roses.
