Esperanza has rust!

Zone Zone 9 | readncoffee added on April 14, 2016 | Answered

My Esperanza again is blooming well, but almost all of its leaves as well as the base of blooms are covered with rust! This is the second year it has had this problem. Could over-watering cause consecutive years of rust? And what should I do?

You are likely seeing the rust fungus due to the growing environment.
Rust Fungus will grow in a damp environment.
Good air circulation will help.
I have luck using Neem Oil as almost a preventative product in an area of my garden that my Hollyhocks always seem to get Rust on them.
Here are some articles with more information.
