Rose rosette disease

Asked June 9, 2018, 10:43 AM EDT

I am pretty sure a couple of my hybrid teas and shrub roses (not knockouts) have rose rosette disease (canes with excessive thorns, red shriveled leaves; non-impacted canes look weakened, blooms turn brown before opening).. Writing to report it and get advice on replacement roses. Anything other than knockouts that are disease resistant for Prince George's County?

Any type of rose that you like would be fine to plant in the same location. Rose rosette disease does not persist in the soil. The mites that spread the disease to not stay around when a rose bush is removed. That said, there are not many roses that are resistant to rose rosette disease. One cultivar, 'Top Gun' is a shrub rose that is scheduled to be released this year.
Rose rosette can be transmitted by mites coming in from wild roses. Some things you could do: leave space between your rose plantings or interplant with other types of plants and/or plant a windbreak (such as an ornamental grass) to try to prevent the movement of mites. https://extension.umd.edu/hgic/rose-rosette-shrub
