No, you can redesign your rose garden by removing plants that are not doing well and transplanting others to new locations.
It will take some research and planning. Start considering the changes you want to make in the late fall or winter so that by early spring, you are ready to start.
The best time to transplant existing rose bushes is in the early spring, while they are still dormant.
It’s also the best time to plant new ones. So don’t try to tackle this project when your plants are actively growing.
