The following was received via email: I'm hoping you can help me, or point me in the direction of someone who can help me, identify the nature of the malady that has affected two of our Rhodos. We recently moved into a house whose garden had been neglected for many years, so we're trying to spruce it up and revive the ill plants. I've attached a couple photos that clearly illustrate the symptoms, which include yellowing of the leaves, leaf spots that look amazingly like severe rust on a car fender, and occasional flower buds that have turned brown and became covered with short black powdery hair. I don't know whether this is caused by disease, bugs, fungi, poor growing conditions, or a symbiotic combination thereof. We appreciate any assistance you can offer. Thank you very much in advance.
