What's the best nursery free of Rose Mosaic virus?
I was checking on Rose Mosaic Virus and found an old thread where aimeekitty posted a picture of her "Queen of Sweden" bought from Roses Unlimited in July. The leaves looked just like Christopher Marlowe that I got from RU in July. I chopped all his infected leaves off, and he was robust in the summer.
We have a mild winter this year, but Christopher Marlowe shriveled up early by frost, while other Austins remained green. Henry_Kusha of Ohio warned that RMV infected roses don't survive the winter well.
I'm used to roses dying in my 5a zone - like the hybrid teas that I planted in full-sun in my last house. But for a zone 5b hardy shrub like Christopher Marlowe to shrivel up is rare. I winter-protected him by mounding soil in a bucket like others, and he's right next to the house.
What's the best nursery free of Rose Mosaic Virus? Many thanks.
