Rose Rosette Disease

I had ordered 4 roses from you guys. While the 3 appear to be doing ok, other than the limited number of flowers compared to our neighbors roses (our roses have lower number of flowers and petals shed faster giving less time to appreciate the flower). However, one rose plant is not doing well and has not turned into my spiky and thorny and smaller (please see picture). How do we remedy this? Anything supplemental we can add to soil?

Customer lives in Virginia planted 4 At Last Roses in April 2021. I was not able to find any information on the reason it is spiky and looks this way. Please advise?

They are likely to think it’s strange that only this one plant has it, but that’s not all that unusual for this particular disease. Whether it will spread to the other roses is hard to say – it is vectored through super tiny mites that just blow in on the wind, so it’s likely, though I don’t think they necessarily need to preemptively remove them if they appear healthy. Rather, they should just monitor them for signs. Here’s more info to share with them:
