Rose rosette disease #864565

Asked April 15, 2024, 10:46 AM EDT

Last year I had to dig out my favorite climbing rose because of rose rosette disease. I dug out all the roots I couild reach, down about 12 inches. Lo and behold, this spring new shoots of this rose are coming up. No visible signs of disease on these shoots. Is there any chance at all that these new shoots could be disease-free? I know I probably will have to dig deeper and get everything out, but wanted to ask first. Many thanks. (This is in Frederick County, rural location)

Hi, 

Unfortunately they are probably not disease free. Rose rosette goes through all of the DNA on the plant and fairly quickly. Also, what is growing up from the roots is most likely a different type of rose since most are graphed on different parent root stock. 

Since the former rose got rose rosette which is carried by mites, any new rose could as well since they travel on the wind. There could be a nearby host they are coming from.
