I just got in 2 roses from John's Miniature Roses and they both have this white powdery stuff on them. I don't have my camera with me today (need to charge the battery), so I can't take a picture. If it's powdery mildew, how do I treat it? It is contagious with other plants/roses? I got in Ernie & Bees Knees, the other two are on back order all the way to June.
I will NEVER order from Heirloom/John's Miniatures again.
