Rose rosette disease is caused by a virus or viruslike organism. It can be spread by mites and insects that feed first on infected plants then move on to other, healthy ones. The virus does not persist in the soil, so as long as you got rid of all the root systems of the infected plants, you should be able to replant in the same area. However, keep in mind that your previous plants became infected in this location, so you may need to track down the source of the disease. It's likely that there may be wild multiflora roses growing nearby that are infected. Try to find and eradicate them so that your new plantings will be less likely to become infected.
