Why does my rose plant have a white film substance on it’s leaves and flowers?
February 82010
My rose plant has a white (looks like mold almost) on it’s leaves and flowers. It is spreading around the plant. It was just on one section of leaves, now it’s on almost the whole plant. flowers and all. Any suggestions on what it is and how to treat it?
Spt is correct, Powdery Mildew, brilliant as usual S! Spectracide 3 in 1 available at Lowz, HomeyD, Wallyworld
Do Not rinse it off. Powdery mildew is caused by too much humidity and not enough air flow.
