"If you grow roses, stories about Rose Rosette Disease can seem like a horror movie. Does it scare you so badly that you refuse to plant roses and want to burn or rip out every rosebush in the neighborhood as if it was a photosynthetic Frankenstein?!? Okay, that�s an exaggerated scenario, but plant diseases can make gardeners reconsider whether susceptible plants are worth the risk. As plant professionals, it is our job to make sure our customers not only have the facts, but clean plants."
