sick roses
My roses are sick. The first sign is a slight variation in color that lightens and spreads until holes develop in the leaf. I am removing the diseased leaves and throwing them away to try to prevent any spreading. The blooms appear healthy at this point. What else can I do? It is in direct sunlight and in its own bed with some lilies and groundcover.

Thanks for writing. Without being able to see your rose in person, I can't say exactly what's going on...this free service rally isn't meant for diagnosing plant problems like this where an exmination of the plant is necessary.


That said, pale rose leaves may develop from virus diseases (to which there's no cure and the plant should be removed and thrown in the trash to prevent the virus from spreading), poor soil nutrition, powdery mildew (which starts as a grey or silvery powder on leaf surfaces and eventually turns them yellow), and black spot (which turns leaves yellow with black spots).
