So sorry to hear this. If it truly is rose rosette disease, there is not much one can do. If you dig out the soils in the area of each rosebush about 30 inches in diameter by at least 18 inches deep, sort out all the root matter you can, then mix with a good bagged garden soil with mulch in it. You should be able to replant whenever you are ready to. I will provide you a link on some rose rosette information as well. Link: https://roserosette.org/
